TRIZ/USIT Paper: Creative Problem-Solving Methodologies TRIZ/USIT: Overview of My 14 Years in Research, Education, and Promotion (Mar. 13, 2012), (Mar. 23, 2012) 
Toru Nakagawa (Osaka Gakuin Unversity), Jan. 6, 2012, To be published in "The Bulletin of the Cultural and Natural Sciences in Osaka Gakuin University", No. 64, March 2012; Posted in "TRIZ Home Page in Japan" in Japanese, on Mar. 13, 2012; English translation: March 22, 2012.
This article is an overview of my activities for the 14 years (from Apr. 1998 to Mar. 2012) while I have been working for Osaka Gakuin University. On retiring the University by the end of March at the preset age (70) (+ 1 extra), I wrote it for a Bulletin of OGU, and under the permission of the Bulletin I am posting it here in my Web site in Japanese and in English translation. PDF(32 pages, 795 KB). Its Absract is:
"The core of my working activities has been the research on TRIZ ('Theory of Inventive Problem Solving') and USIT ('Unified Structured Inventive Thinking'). I have attended and presented at international conferences on TRIZ every year, and extended USIT (i.e. a unified and simplified TRIZ) further to find a new paradigm called 'Six-Box Scheme' for creative problem solving. In the field of education, besides several other classes on ordinary information science, I have been teaching on this theme in a lecture class and also in 3rd and 4th year seminars, where my students and I have made several successful case studies of solving familiar problems.
On the basis of these research and education, I have been working for the promotion of penetration of TRIZ and USIT. I established a public Web site "TRIZ Home Page in Japan" and have been operating it for these 13 years. Founding and joining the Japan TRIZ Society, we have held 'TRIZ Symposium in Japan' annually. With further development and wider penetration, the methodologies of creative problem solving will support the movement of technological innovation and will cultivate human resources having the capability of creative thinking, I hope."I would like to express my sincere thanks to all the people who have been supporting me for these years.
Even after my formal retirement, Osaka Gakuin University will kindly contiue to support me operating this "TRIZ Home Page in Japan" and using my email address at OGU just as before. I wish to keep my activities going on as long as my health allows me.

Introduction by Toru Nakagawa (Osaka Gakuin Univ.), An excerpt from 'Personal Report of Japan TRIZ Symposium 2009', posted on Nov. 23, 2009
This Keynote starts with the questions 'why more than 90 % of projects fail to deliver their products to the market' and 'why more than 90 % of products fail in the market'. The Author's main postulates are 'Innovation happens when the Voice of the customer matches with the Voice of the system', and 'Understanding the Voice of the customer is crucial for the innovation, but TRIZ lacks in such a method'. Thus he proposes a new general scheme for revealing the real Voice of the customer, on the basis of his team's 8 years of research. It has 3 steps: (1) To identify the desired functionality. (2) Combination of (a) to understand the change in population, (b) to understand the characteristics of the generation of customers, and (c) to consider the characteristic behaviors of customers. (3) To understand many relevant trends of the market and the enforcing and conflicting relationships among such trends, and finally to consider the desires of solving the contradictions between trends as the Voice of the customers. The Author tries to make this scheme general by adopting some 'Theories of Everything'; particularly Generation Cycles in (2b) and Spiral Dynamics in (2c) and by considering 1000 trends in (3). The Author's endeavor to distill the essences from numerous methods and business books is amazing, and has resulted an interesting presentation of all insights at one place in the form borrowed from the Periodical Table of Atoms. An excellent lecture from which we can learn a lot.

Introduction by Toru Nakagawa (Osaka Gakuin Univ.), An excerpt from 'Personal Report of Japan TRIZ Symposium 2008', posted on Oct. 26, 2008.
Paper printed in the Proceedings both in English and in Japanese, but not presented because of the author's absence. This paper poses a question: "TRIZ certainly helps us solve difficult problems containing contradictions. Such inventive solutions, however, can smoothly pass the prosecution process of patent application? TRIZ guides us to use various models, especially Inventive Principles and various examples in other fields. Does this mean we are relying on prior arts? Is there any risks that IPO examiners regard our inventive solutions obvious with respect to prior arts?" -- The Author demonstrates a case study of an inventive patent application in the field of functional textile design and examines its patentablity with respect to the prior arts. His conclusion is: "Which methodology (e.g. TRIZ) is used during the problem solving is not a matter in the patent prosecution process. Novelty or unobviousness matters wih respect to the prior arts. Thus (inventive) solutions obtained with TRIZ have to be examined in this viewpoint before the patent application. You have to search prior arts and limit your claims carefully to obtain patent protection." Nakagawa has translated this fine paper into Japanese.

Introduction by Toru Nakagawa (Osaka Gakuin Univ.), An excerpt from 'Personal Report of Japan TRIZ Symposium 2008', posted on Oct. 26, 2008.
"Differences" is the gap between the desire and the reality. We want to resolve the differences in all the activities of goal setting, problem recognition, designing, problem solving, etc. The author has been constructing his own theoretical framework to handling the difference resolution and has developed his way of diagrammatic representation of such systems and activities. His 14 papers written since 2003 were posted last year in this Web site
Japan TRIZ Symp. 2008 Presentation: "A Comparison of the Problem Solving and Creativity Potential Shown in Engineers using TRIZ or Lean/ 6 Sigma"
Paul Filmore (University of Plymouth, UK), Oral Presentation at The Fourth TRIZ Symposium in Japan, Held by Japan TRIZ Society on Sept. 10-12, 2008 at Laforet Biwako, Moriyama, Shiga, Japan,
Introduction by Toru Nakagawa (Osaka Gakuin Univ.), Originally written in 'Personal Report of Japan TRIZ Symposium 2008', posted on Oct. 26, 2008.
The presentation is related to the concepts of 'Highly effective people/engineers'. 'Highly effective engineers' DOES NOT MEAN at all the skillful engineers who can work on a given job with high efficiency without thinking on the problem, on the contrary they mean the people (or engineers) who can break their own mindsets (or Psychological Inertia, in TRIZ terms) flexibly and can creatively solve their problems. The Author leraned the concept of 'Highly effective people' from a large number of references, and applied it to obtain the concept of 'Highly effective engineers'. In order to be 'highly effective', what kind of attributes are necessary, what kind of tools and methods are useful to cultivate such attributes and to apply to the real probelm situations, the Author is discussing. Many tools in TRIZ can serve to do that, this is one of the main conclusions by the Author. The Author also sent inquiries to several practitioners of Lean Engineering and Six Sigma. And he found that these two methodologies have much room to enhance the methods in this sense.
Japan TRIZ Symp.2008 Keynote: "Directions for Future TRIZ Development and Applications"
Sergei Ikovenko (GEN3 Partners / MIT, USA), Keynote Lecture presented at The Fourth TRIZ Symposium in Japan, Held by Japan TRIZ Society on Sept. 10-12, 2008 at Laforet Biwako, Moriyama, Shiga, Japan,
Introduction by Toru Nakagawa (Osaka Gakuin Univ.), Originally written in 'Personal Report of Japan TRIZ Symposium 2008', posted on Oct. 26, 2008.
A page of Introduction to Ikovenko's Keynote is posted both in English and in Japanese. Dr. Ikovenko talks about the overview of TRIZ. In the global scale, TRIZ is still in the Infancy stage in its S-curve. Any product/service in the Infancy stage should find its proper niche for supporting its growth. For TRIZ, the proper niche is the problem solving in technologies, without doubt. Thus we must make TRIZ strong and successful in such an area. For this purpose we need to have the eyes of business managers in technology. The concept of Main Strategic Parameters of Value (MSPV) is useful. There are some more research directions in TRIZ. All together, TRIZ is proceeding towards 'the Science of Innovation'. -- This Keynote gives a clear view of the future of TRIZ.
TRIZ/USIT Paper: "Extension of USIT in Japan: A New Paradigm for Creative Problem Solving" (Sept. 18, 2008)
Toru Nakagawa (Osaka Gakuin Univ.), Presented at The Fourth TRIZ Symposium in Japan, Held by Japan TRIZ Society on Sept. 10-12, 2008 at Laforet Biwako, Moriyama, Shiga, Japan
I have reviewed how USIT was introduced in Japan and has been extended in Japan for these 10 years. (1) I introduced USIT into Japan as an easy-to-learn TRIZ. It forms a basis of my 'Slow-but-Steady Strategy' of introducing TRIZ into Japan. (2) We reorganized all the solution generation methods in TRIZ into the framewok of USIT and constructed a system of USIT Operators, having 5 principal methods and 32 sub-methods. This makes USIT a next-generation TRIZ, forming a basis of 'Steady Strategy' of penetrating TRIZ in Japan. (3) Data-flow repesentation of USIT gave the concept of 'Six Box Scheme', which has been realized as a New Paradigm for Creative Problem Solving. (4) Teaching to university students and training of industrial engineers have been estabished, and applications to real industrial projects have been carried out in companies. With all these activities, USIT has been contributing to promote TRIZ in a way easy to learn and apply, i.e. a unique feature of the TRIZ community in Japan in comparison to other countries.

TRIZ Paper: "A Method of Resolving Differences Based on the Concepts of Functions and Process Objects: Part 2" (Dec. 9, 2007)
Toshio Takahara ( ), Presented at the Third TRIZ Symposium in Japan Held by 'Japan TRIZ CB' at TOSHIBA Kenshu Center, Yokohama, Japan, on Aug. 30 - Sept. 1, 2007
[This is a highly theoretical paper. Though the paper was presented in a Poster session, full papers were published in the Proceedings and posted here both in English and in Japanese. The Author's way of representing 'Cause-Effect Diagrams' is clear and informative (Nakagawa's 'Personal Report of the TRIZ Symposium' explains this portion of the paper). With the term of 'Resolving differences', the Author is trying to make a new integrated framework of problem solving, making new function, and idealization. The paper is difficult to understand, but I now feel a new integral theory is emerging here. The page contains Nakagawa's introduction, Extended Abstract, and the full paper in PDF

TRIZ Symposium paper and slides: "Technology Forecast by the 9-Window Method and the FDMS Cycle" (Jan. 7, 2007)
Kunio Fukatsu （TOSHIBA Social Automation Systems), Presented at The Second TRIZ Symposium in Japan Held by the Collaborative Board of TRIZ Promoters and Users in Japan, on Aug. 31 - Sept. 2, 2006, at Pana-Hills Osaka, Suita, Osaka.
[The Author has been working for developing social automation systems especially with paper and card handling functions. In the present study, he characterizes the 4 stages of the S-curve evolution as the 'FDMS Cycle' composed of Function realization, Discrimination, Multifunction, and Standardization stages. Then he demonstrated the FDMS Cycles of the banks' ATM system in relation with those of its subsystems, i.e. passbook printer and page turning element, and concluded that the Function realization of a subsystem urges the system to proceed a step further in the FDMS Cycle.

Keynote Lecture: "A Simple Theory Underlying Structured Problem-Solving Methodologies －ASIT, TRIZ, USIT (and others)" (Oct. 2, 2006)
Ed Sickafus (Ntelleck, USA, Orignator of USIT), Keynote Lecture presented at The Second TRIZ Symposium in Japan, Held by Japan TRIZ CB, on Aug. 31 - Sept. 2, 2006, at Pana-Hills Osaka, Suita City, Osaka, Japan.
[Sickafus is the originator of USIT. Any structured problem solving methodology, such as TRIZ, USIT, etc., teaches us to solve problems following clear structure. However, Sickafus argues, the human brains work more freely, not only at the conscious level but also at the subconscious level. Thus he advises us to utilize such a power of our brains. While the consious uses logic, the subconsious can be activated with metaphores, such as images and words. Thus he advises us to solve problems without being constrained with the structured logic. In Japanese traditional art students are trained to "Enter the Form first, and then get out of it". Slides (PDF, 344 KB)
Paper in Japanese translation: "How to Deal with Cost-Related Issues in TRIZ" (Jul 18, 2006)
Ellen Domb (PQR Group and the TRIZ Journal, USA), Presented at the ETRIA World Conference "TRIZ Future 2005" held at Graz, Austria on Nov. 16-18, 2005. Japanese translation by Toru Nakagawa (OGU) on Jul. 12, 2006
[Paper presented last November, and has been waiting in the 'To Do List for TRIZ'. Many of TRIZ beginners try to deal with cost-related issues, meet difficulties, and decide that TRIZ is of no use. Since the cost problem covers a very wide range of issues, we need careful analyses, the author says. Besides, we TRIZ experts should construct/re-arrange TRIZ methods in such a way that TRIZ beginners can tackle cost-related problems with TRIZ, the author says and actually suggests a version of such an approach.

'Removing weeds' has been a much labor work since ancient days. It appears to be a simple problem at first sight, but actually is a complex problem containing a diversity of requirements. Thus in the present study we have considered to reveal the problem in various aspects, such as purposes, goals of finishing, problem situations (e.g., ground, sorts of weeds, distributions of crops and weeds, etc.) and have thought of a variety of methods in the aspects of their intentions, tools, mechanisms, etc. and have evaluated the methods. The paper stress that before trying to solve a specific problem, we need to understand the structure of the problem from such a variety of aspects, regardless of using TRIZ or not.

Introduction (in English) by Toru Nakagawa (Osaka Gakuin Univ.), An excerpt from 'Personal Report of Japan TRIZ Symposium 2009' posted on Dec. 24, 2009
This paper aims at analyzing a number of new technologies familiar to us with the eyes of USIT and accumulating them in a collection of case studies. The analysis puts much emphasis on the close observation of mechanism/process of the problem system and on the understanding of the root causes. The Authors classify the problems into 4 classes, i.e., A: Excess of function, B. Insufficiency of function, C: Instability of function, and D: Harmful effects, and further into 16 sub-classes in accordance with the generalized categories of root causes. In the analysis of case studies, the Authors try to assign the essence of inventors' ideas in terms of the USIT Operators (i.e. a set of 32 sub-operators derived from all the idea generation methods in TRIZ). In this manner, the Authors are developing an Index Matrix where appropriate frequently-used USIT Operators can be obtained for each type of problems. In comparison to the Altshuller's Contradiction Matrix, the USIT Index Matrix is much more generalized (i.e. only 16 problem types in place of 39x39) and straightforward.

The paper overviews the history of introducing TRIZ in Korea, and states that TRIZ in Korea is now at the stage of rapid growth of the S-curve. The most important trigger of the growth was the successful technical case studies achieved in Samsung group companies by the Russian TRIZ experts around (or just before) 2004 and the fact that the managements of the big companies recognized them and promoted TRIZ actively. Then the needs of training engineers in the companies led to the effective use of on-line training courses. According to the Author, many books on TRIZ were published in the Korean language, and several universities have started the regular classes on the subject of creative engineering design on the basis of TRIZ. The Author summarizes 9 main success factors of TRIZ promotion in Korea.
In Nakagawa's Personal Report, I briefly discussed on the current situations of TRIZ activities in Japan from K.W. Lee's 9 viewpoints plus 6 more different ones

Introduction by Toru Nakagawa (Osaka Gakuin Univ.), An excerpt from 'Personal Report of Japan TRIZ Symposium 2009', posted on Dec. 24, 2009
As the goal of a regional (i.e. sub-national) integrated energy planning, the project states that the plan must be "environmentally friendly, technically reliable, institutionally sound, socially acceptable, cost-effective, and supporting long-term regional sustainable development". The project must manage a complex and large-scale task which involves not only technical issues but also social, economic, and many other issues. The present paper has introduced the OTSM-TRIZ methodology as the framework of planning. OTSM-TRIZ is a further extension of TRIZ, started by Altshuller and later developed mostly by Nikolai Khomenko. The present paper serves as an nice introduction to the OTSM-TRIZ.
The methodology aims at understanding the complex, large-scale problem in the framework of Altshuller's powerful thinking, representing the routes from the reality to most desirable solutions with a network flow diagram for revealing the barriers or contradictions, and solving those contradictions with TRIZ. They also have a practical overall process model for preparing, analyzing, prioritizing & decision-making, and implementing & monitoring, in the cooperation with other groups of people including decision makers.
This paper may be useful for you to learn about OTSM-TRIZ before the coming lectures by Nikolai Khomenko: Keynote Lecture at Japan TRIZ Symposium 2010 (on Sept. 9-11) and one-day lecture in "OTSM-TRIZ Introduction Seminar" (on Sept. 8, 2010).

Introduction by Toru Nakagawa (Osaka Gakuin Univ.), An excerpt from 'Personal Report of Japan TRIZ Symposium 2009', posted on Dec. 6, 2009
Panasonic Communications Company (PCC) introduced TRIZ since 2001 and has been actively used the integrated set of scientific techniques including QFD-TRIZ-Taguchi Method (as well as CAD/CAE) in a company-wide scale. It is perhaps the company where TRIZ has been applied most actively and widely in Japan. Nevertheless, engineers in development projects are apt not to use such TRIZ-based scientific techniques because of being too busy to apply them in their orthodox forms. Thus the Authors made the methods 'scalable' corresponding to the demands of the projects and easier to apply. The new method has a process of 3 main phases: (1) First, to generate many fundamental (or preliminary, existing) ideas of functions and to make a tree-style Function Map. (2) Then, to select the areas for addressing the solution efforts and to force the members to create new/inventive ideas in managed brainstorming sessions. (3) Finally, to evaluate various ideas generated so far and to enhance the highly-evaluated ideas by combining subsidiary ideas, thinking deeply, and looking from competitors' eyes, etc. and to make them the solutions for possible implementation and patent filing. This method, though not appearing like a TRIZ any more t first sight, is firmly underlaid by TRIZ. The industrial TRIZ practitioners have really digested TRIZ into a new form for real applications. This paper won the Award of 'Best Presentation For Me' as the results of Japanese participants voting at the Symposium.

Introduction by Toru Nakagawa (Osaka Gakuin Univ.), An excerpt from 'Personal Report of Japan TRIZ Symposium 2009', posted on Dec. 24, 2009
The Authors introduced TRIZ together wth QFD and TM and applied them to the real project of developing a new product, i.e. a high-speed response pneumatic air valve. They have tried to capture real voices of customers with QFD. The technical problems thus assigned were challenged by the Authors with TRIZ. Some of the new solution concepts obtained with TRIZ were beyond their experiences and expertise. Thus for minimizing the risks in the new product development, they applied TM (Taguchi Method) in designing the test parameters and used CAD/CAE software for the simulation testing of various design choices. The report describes details of the newly developed product, in its performance, inner structure, cases of applications, etc.
The three methods were all new at first to the Authors and to the company, they report. They requested only one Japanese consultant to instruct all the three methods and to coach the project throughout the course. This presentation obtained "The best presentation for me" Award by the voting of Japanese participants during the Symposim. Congratulations!

Hiroshi Kanno (Tohoku RICOH Co., Ltd.), Presented at The Fourth TRIZ Symposium in Japan, Held by Japan TRIZ Society on Sept. 10-12, 2008 at Laforet Biwako, Moriyama, Shiga, Japan,
Introduction by Toru Nakagawa (Osaka Gakuin Univ.), An excerpt from 'Personal Report of Japan TRIZ Symposium 2008', posted on Oct. 26, 2008.
This is an excellent case study paper which reports on the development of a duplex printing machine 'RICOH Satelio Duo 8' with the help of TRIZ and USIT. The digital duplicator uses the mimeography, which uses the pseudo drying of printer ink due to penetraton into the paper fibers. Thus the paper having printed fresh on a side can not be printed on the other side without making the printer roler dirty. This problem has long made a dual printer impossible. On learning basic TRIZ, the Author got the idea of using only one printer drum for printing the both sides and challenged the development of the dual printer. After various trials, the SLP modeling helped to solve the dirty-ink problem by developing a beads-roler. Author also learned USIT later and used it for solving many subsequent problems. The new dual printing machine thus developed with relatively simple modifications has doubled the throughput. -- This presenration has won the Award by the prticipants voting. The Japan TRIZ Society is requesting the company for the permission to post the full set of presentation slides publicly in its Web site, but has not obtained it yet. Nakagawa has translated his introduction to this paper into Japanese and is posting here.

Introduction by Toru Nakagawa (Osaka Gakuin Univ.), An excerpt from 'Personal Report of Japan TRIZ Symposium 2008', posted on Oct. 26, 2008.
The Author writes in the Abstract: "Conventional textbooks on noise and vibration (NV) control almost always describe analysis methods only and don’t provide methods of solving problems. On the other hand, handbooks contain solutions of “specific” problems, but they don’t necessary give readers solutions to general problems. In this study, the author tries to connect NV theory with TRIZ idea of solving problems for giving engineers rules of thumb of NV technology. This method converts specific concrete problems into abstract general problems by sorting symptoms by frequency, time dependency, etc. Then these general problems are placed in suitable categories classified by equation of motion in NV theory. Then rules of thumb described with problem solving manner is given." The paper of this work has been accepted for publication in International Journal of Vehicle Noise and Vibration (IJVNV).

Toru Nakagawa, Tomoyuki Itoh, and Masanobu Tsukamoto (Osaka Gakuin University), Presented at Fifth TRIZ Symposium in Japan, Held on Sept. 10-12, 2009 at National Women's Education Center (NWEC), Saitama, Japan; and also presented at ETRIA "TRIZ Future 2009" Conference, Held on November 4-6, 2009 at The Polytechnic University of Timisoara, Romania.
This paper is an extension of my students' thesis works. Cords and cables often cause troubles by getting complex and entangled. Instead of trying to find some specific solutions to this common widely-spread problem, we thought it worthwhile to collect many known solutions and to systematize them. We collected various solution examples and then tried to classify them in terms of their functions. A system of solutions achieved by a bottom-up classification, however, was not found convincing, so we needed a more systematic approach. Introduction and extension of the scope of system was found useful. The scopes of (A) a single cord/cable, (B) multiple cords/cables, (C) connecting parts between cords/cables and devices, and (D) the whole system with cords/cables and devices were considered step by step. This approach has provided a consistent system of known solutions, and has given us some clews to think further ahead. The English page holds the full paper in HTML

TRIZ Paper & Case Study: "The Super Stream Augmented Approach for TRIZ and its Application to Aviation Safety." (Posted: Jun. 16, 2009)
Shahid Saleem A. Arshad, Ph.D.(Applied Innovations, Sydney, Australia), May 15, 2009.
This paper deals with the problems of the speed sensoring system of airplanes. The Author explains the weak points of the current "pitot + static system", whose defects caused several big airplane crash accidents in the history. He suggests 25 concepts for impoving and resolving the problem, as a case study for demonstrating his own problem solving method. Two weeks ago, on June 1, an Airbus A330 of Air France plunged into the Atlantic Ocean off Brazil, causing 228 victims. The trouble in the speed sensor 'pitot + static' system is most suspected.as the possible cause of the accident. Just after such an unfortunate accident, the present paper is timely for you to learn.

Tomohiko Katagiri, Toshiaki Tsuchizawa, and Takeshi Yamanouchi (Koganei Co., Ltd.), Oral Presentation at The Fourth TRIZ Symposium in Japan, Held by Japan TRIZ Society on Sept. 10-12, 2008 at Laforet Biwako, Moriyama, Shiga, Japan,
Introduction by Toru Nakagawa (Osaka Gakuin Univ.), Originally written in 'Personal Report of Japan TRIZ Symposium 2008', posted on Oct. 26, 2008. (Apr. 21, 2009)
A page of Introduction is written by Nakagawa to the case study of promoting TRIZ in an SME. Koganei Co. is a manufacturer of aero pneumatic equipments, having about 800 employees. Under the severe competitive situations, the Authors were convinced 2 years ago with the needs of innovating their product development process. Thus the Authors started to introduce and apply the set of QFD, TRIZ and TM (Taguchi Method) to their three pilot projects. It is interesting that the company requested only one consultant to guide the team in all the three methods. The users, not the consultant, reported their current activities and achievements vividly. This presentation has won the Second Place of the Presentation Awards according to the votes by Japanese participants. Congratulations!! It is a pity that only 4 slides are translated into English from the 28 slides in Japanese (English translation was supported by J. Shigeta (Hitachi)).
Japan TRIZ Symp. 2008 Presentation: "Why Water Striders can stand and slide on the Water?: A Summer Homework by Son and Father with TRIZ"
Taichiro Miyanishi (2nd Grader, Kenroku Junior High School, Kanazawa /Son), Katsuya Miyanishi ( /Father), Oral Presentation at The Fourth TRIZ Symposium in Japan, Held by Japan TRIZ Society on Sept. 10-12, 2008 at Laforet Biwako, Moriyama, Shiga, Japan,
Introduction by Toru Nakagawa (Osaka Gakuin Univ.), Originally written in 'Personal Report of Japan TRIZ Symposium 2008', posted on Oct. 26, 2008. (Apr. 21, 2009)
A page of Introduction written by Nakagawa to Miyanishi family's wonderful presentation is posted here in English and in Japanese. The story presented at the Symposium started when a 12 year boy, Taichiro, talked to his father: 'As a summer homework, I want to learn why water striders can stand and slide on the water surface'. Father, Katsuya, thought it could be an interesting work by use of TRIZ thinking, which he learned only half a year ago. With the promice of 'Never to scold', the boy worked on this problem under the Father's guidance. They tried to think of various ideas for standing on the water surface, with reference to various phenomena and effects. Then they checked their ideas at the library, and further built toy models of water striders with the materials available at home. Thus their work is neither a book/internet survey of knowledge, nor observation of the facts, but rather idea generation and verification on the basis of TRIZ thinking. At the end of the Symposium presentation, the boy made a video talk and said 'I enjoyed the work very much and found the TRIZ thinking process interesting'. This presentation won the First Place of the Presentation Award according to the votes by the participants. Congratulations!! This is a monumental work where TRIZ was actively used by a 12 year boy in Japan.
Japan TRIZ Symp.2008 Invited Talk: "TRIZ activity in Corporate R&D Division －Application to system, method, and software technology －"
Yojiro Fukushima (Matsushita Electric Industrial Co., Ltd.), Invited Talk presented at The Fourth TRIZ Symposium in Japan, Held by Japan TRIZ Society on Sept. 10-12, 2008 at Laforet Biwako, Moriyama, Shiga, Japan,
Introduction by Toru Nakagawa (Osaka Gakuin Univ.), Originally written in 'Personal Report of Japan TRIZ Symposium 2008', posted on Oct. 26, 2008.
A page of Introduction to Fukishima's Invited Talk is posted both in English and in Japanese. Fukshima has reported his 5-years experiences of applying TRIZ to 150 real projects in the field of IT and software. The TRIZ team gives TRIZ trainings to engineers and also guides/supports engineers in real job projects. In the early stages of planning, problem definition, problem analysis and solution generation, the TRIZ team guides the engineers with TRIZ and some other tools. Such projects have to pass the interim review and final review by the managers and staff of the division; this scheme makes the TRIZ application serious and practical so as to fit with the organization's policies. They have applied TRIZ in a flexible manner adopting it into IT/software fields. The TRIZ team is the first eager readers of Japanese draft version of Umakant Mishra's book "TRIZ Principles for Information Technology". -- Fukushima's presentation is amazing in the new field of TRIZ application, i.e. IT/software.
Japan TRIZ Symp.2008 Keynote: "TRIZ Development at Intel Corporation"
Amir Roggel (Intel, Israel), Keynote Lecture presented at The Fourth TRIZ Symposium in Japan, Held by Japan TRIZ Society on Sept. 10-12, 2008 at Laforet Biwako, Moriyama, Shiga, Japan,
Introduction by Toru Nakagawa (Osaka Gakuin Univ.), Originally written in 'Personal Report of Japan TRIZ Symposium 2008', posted on Oct. 26, 2008.
A page of Introduction to Roggel's Keynote is posted both in English and in Japanese. Amir Roggel presented on the promotion of TRIZ in the manufacturing divisions in Intel since around 2002. In the field of manufcturing they have 4 main areas of problem: Ramping new products into high volume manufacturing, Yields, Tool productivity, and Cost and agility. For each area they use proper TRIZ tools. By training engineers and applying TRIZ in real projects, they have made a lot of accomplishments. 3 case studies were reported by colleagues in Intel Malaysia. TRIZ is now the indispensible tool for innovation in Intel, Amir Roggel says.
TRIZ/USIT Case Study: "Applying TRIZ/USIT to A Social & Technical Problem: Auto-locking Door System of Apartment Building" (Mar. 2, 2009)
Toru Nakagawa and Arata Fujita (Osaka Gakuin University), Presented at ETRIA "TRIZ Future 2008" Conference, held on November 5-7, 2008 at The University of Twente, Enschede, The Netherlands.
It is a well-known security problem that unauthorized persons can enter the auto-locking entrance door of apartment buildings just by following the preceding residents. Students' discussions were facilitated with TRIZ/USIT to tackle this problem. We found three root causes: the door is closed slowly for safety reasons, residents allow unauthorized persons to enter, and there is no effective social rule to follow when two parties happen to meet at the entrance door. Solution ideas were generated step by step by discussions. A concept of an IT-based logical door system was built to monitor the number of persons who were authorized and also the number who entered. Any group leader has to authenticate himself and to declare the number of accompanied persons whenever the door is open or not. With the new design choice in technology, all the associated psycological and social problems have been solved, hopefully. Paper
Research Note: "Benefits of Drawing Diagrams (1) Experiences from the USIT Case Study: A Mom’s Bicycle for Safely Carrying Two Children" (Feb. 22, 2009)
Toru Nakagawa (Osaka Gakuin Univ.), Feb. 22, 2009
Here I have written down my recent experiences that by drawing a diagram we realized some important findings. In relation to the USIT case study of "A Mom's Bicycle for Safely Carrying Two Children", I have written the followig topics: (1) Effect of the height of children's seats: front view figure at the critical timing of falling over. (2) Image of an Ideal system: a figure where no concrete things are drawn. (3) Functional diagram of a mom's bicycle carrying two children: strength of simpler and clearer diagrams. (4) Solution concepts coming from the Functional diagrams. (5) Separating the parent far from the front wheel: Separation of the handlebar shaft and the front fork shaft, carrying two children in front of the parent. These cases are described with the patterns of: Problem situations, Guideline of the method, Former/conventional drawings, New drawings, New findings from the new drawings, and Lessons learnt. These articles also serve to record know-hows of USIT.

Kunio Fukatsu (Toshiba Social Automation Systems), Presented at the Third TRIZ Symposium in Japan 2007 Held by 'Japan TRIZ CB' at TOSHIBA Kenshu Center, Yokohama, Japan, on Aug. 30 - Sept. 1, 2007
[Technical knowledge transfer is a current big issue in Japan because many active people in the after-war baby-boom generation are going to retire around the age of 60. The Author has built an intensive intranet Web site of professional knowledge, but has realized its negative effect because such knowledge get obsolete rapidly. Learning TRIZ/USIT recently, he has realized the need to transfer the capability of creative problem solving. He describes a case study carried out in a 2-day USIT Training Seminar.

[In the process of printing the adhesive on a PDB, the adhesive lifted up with the mask sometimes generates bubbles, breading-out, and clogging and they later cause various defects. This problem was analyzed and solved by using various TRIZ tools in a standard way. With the help of Effects knowlede base, the adhesive was improved in its properties on the basis of its microstructure. This paper is useful because of its detailed description of the problem solving process. English page contains Abstract, Nakagawa's introduction

[This case study paper is, as far as I know, the first publication in the world on the application of TRIZ to a real problem in the IT field. The Authors worked on TRIZ for IT around 1999-2000 in the Central Resaerch Lab of Hitachi, to adapt the Matrix parameters and Inventive Principles to the field of computer architecture and to make a reduced Contradiction Matrix for IT of size 14x14. They also applied the Matrix to real problems such as the IT systems for Internet Data Center and succeeded to obtain paptents and to implement the ideas in their company's products.

[Excellent paper presented at the Japan TRIZ Symposium 2007. This case study is most impressive in many points: achieving to solve a big problem in a short time by generating many solution ideas, deriving effective measures, executing many measures at once, etc. In the photos of the slides we can see that people seriously got involved in this project and had experienced the change in their mind. This is also an excellent case study for stepping up the TQC style activities into much elaborated one with the philosophy of TRIZ. The page contains Abstract, Nakagawa's introduction
TRIZ/USIT Case Study Paper: "Education and Training of Creative Problem Solving Thinking with TRIZ/USIT" (Nov. 18, 2007)
Toru Nakagawa (Osaka Gakuin Univ.), Presented at ETRIA 'TRIZ Future Conference 2007' held on Nov. 6 - 8, 2007 at Frankfurt on Main, Germany
[This paper reports my expereiences of training industry engineers and educating undergraduate students on how to think creatively with TRIZ/USIT in problem solving. The focus is what to teach them. I gradually shifted my emphasis from TRIZ to USIT. For training engineers, 2-Day USIT Training with group practices of real problem solving is found effective. For educating students, giving motivations and basic knowledge is necessary for the education of TRIZ/USIT concepts. Case studies of technical and everyday-life problems are useful for bose targets of people. English HTML page
TRIZ/USIT Case Study Paper: "How to Prevent Unauthorized Persons from Entering the Auto-locking Door of Apartment Building: Applying TRIZ/USIT to A Social & Technical Problem" (Sept. 13, 2007)
Toru Nakagawa and Arata Fujita (Osaka Gakuin Univ.), Presented at the Third TRIZ Symposium in Japan Held by 'Japan TRIZ CB' at TOSHIBA Kenshu Center, Yokohama, Japan, on Aug. 30 - Sept. 1, 2007
This paper is an extension of Fujita's Thesis work supervised by Nakagawa. A concise case study of solving everyday-life problem. Residencial apratment building equips auto-locking door system at the entrance. However unauthorized persons can enter the door easily simply by following a resident, during about 10 seconds of the oen door. This is not a pure technical problem, but rather the problem in the psychology of residents who allow and in the lack of social consensus what to do when two groups happen to meet at the door. With the discussion in the Thesis Class, the root causes of the problem were revealed to find solutions. Rules are now displayed clearly that inside the door is a private zone, that every group must get authenticated, that the authentication should be done regardless the door is open or closed, and that the group should input the current number of memebers, etc. At the same time, a new control system with real-time image recognition capability is installed in order to monitor the number of people who entered the door, and to alarm when any person enters the door exceeding the nuber of authenticated persons. The door is mechanically and physically operated slowly as before for the sake of safety, but an invisible logical door based on information processing is working instantaneously to show signs, notices, and alarms. In this manner the problem of human psychology and social rule is solved and the new rule is ensured by a new technical system. An expert in the security problem commented me 'a cool solution!' in the Symposium. Extended Abstract
TRIZ Case Study Paper: "Super Effects: The Synergistic Effects of TRIZ (The Theory of Inventive Problem Solving): Significance of the Insulated Wirebonding Technology X-Wire" (Sept. 13, 2007)
Gunter Ladewig (PRIMA Performance Ltd., Canada) and Robert Lyn (Microbonds Inc., Canada), Presented at TRIZCON2007: The 9th Annual Altshuller Institute for TRIZ Studies Conference, Held at Louisvile, Kentucky, USA, on Apr. 23-25, 2007.
Japanese translation by Katsunori Ishikawa (Shindengen Electric Manufacturing) and Toru Nakagawa (OGU), Sept. 6, 2007
[This is an excellent case study presented at TRIZCON2007. In semiconductor devices, the perfomance of the chip is limited by the interconnection between chips and between chip and substrate. The current wirebonding technology with non-insulated wires uses only the peripherals of chips for the connection. More advanced technology is currently the Area Array Flip Chip. With reference to the TRIZ Trends of Evolution (especially the Geometrical Evolution of Lines), the phase of 2D lines/curves has not been fully deployed and skipped without solving contradictions, the Author says. They have developed the insulated wires, developed a kit to use the insulated wires on the ordinary widely-spread wirebonding equipments. Their new technology ('X-Wire') can make wirebonding densely and freely without worrying about shortening. The new technology would make a lot of chain reactions of benefits (socalled 'Super Effects') in the semiconductor industries, the Authors expect. It is remarkable that TRIZ has given a clear guideline in the technology development. Nakagawa evaluated this paper highly in his Personal Report of TRIZCON.

Japanese translation by Masahiro Saitoh (Yanmar Co.) and Toru Nakagawa (OGU), Aug. 4, 2007
[This is a paper on an amazing invention and its evaluation with TRIZ. The invention is a new type of Motor (in its basic meaning of 'generating motion') which does not use electricity. The invention is 'A new type of Motor having two (or multiple) rotors of nonlinear spiral teeth'. Though ordinary combustion engines generate reciprocal motions of a piston, the new motor generates rotational motions of shafts directly. By applying a part of this invention concept, pumps and screws (or marine propeller) can be realized. In fact, the authors built a new type of marine propeller and demonstrated it successfully in a public experiment. The area of application of this invention is suposed to cover combustion engines, Diesel engines, rotary engines, turbines, electric motors, pumps, compressors, vaccuum pumps, propellers, marine propellers, etc. Reading this brief introduction, you must feel confusing, puzzled, and unbelievable; then why don't you read the original paper three times closely. As a matter of fact the new marine propeller was demonstrated successfully in May 2004. I reported this paper in my 'Personal Report of ETRIA TFC2007'

[In using IT, we currently buy hardwares, buy software, and run our own IT centers ('On Premise' IT); in future suppliers will operate the IT centers to run sotware on the servers while business users use them through browsers bysending their data to the centers ('On Demand' IT). Google for searching is the example of On Demand IT. The Author finds that many TRIZ Principles and Trends of Evolution support this shift, thus possibly turning into a major shift in IT. -- This is a valuable paper for viewing IT with TRIZ and for obtaining guiding principles in IT from TRIZ.

[Due to getting smaller and smaller, semiconductor devices face with the increasing risk of being damaged by Electrostatic discharge (ESD). ESD control need to be installed in the devices themselves and also in the manufacturing and handling processes. The present paper reviews the existing techniques of both the device ESD control and the manufacturing ESD control with the eyes of TRIZ, and explains them in terms of TRIZ 40 Inventive Principles. The paper is a nice case study to understand a specific field of (empirical) technology on the basis of TRIZ. This approach seems to be effectively applicable to various fields, e.g., engineering, agriculture, health care, software development, business and management, etc. Nakagawa's introduction is taken from his 'Personal Report of TRIZCON2006'
Case Study: Problem Solving with VE: "Development of a Movable Office of Ticket Vending Machines for the Construction Works of Remodeling JR Osaka Station" (Apr. 5, 2007)
Kouji Katayama (Western Japan Railroad), Presented at The 38th Kansai Value Engineering Conference, Held by Japan Value Engineering Society, on Feb. 16, 2007, at Osaka International Communication Center, Tennoji-ku, Osaka.
[For the construction works for remodeling JR Osaka Station, an office of ticket vending machines was found necessary to move and reinstall several times. Conventional way of moving the office takes 40 days with temporary enclosures at the new or old location, causing much inconvenience with narrowed pathways. The author developed a method of moving it just one overnight and performed it successfully. The keypoint in the problem solving method in this report seems to be the processes of clarifying the problem in a hierarchical scheme, converting the expressions of problems into those of tasks/targets, and then generating a hierachical system of target solutions. This is one of VE methods, the author says, but it should certainly be useful in problem solving with TRIZ/USIT. An excellent case study! The paper is posted in PDF
TRIZ Symposium slides: "Introducing USIT in Matsushita Electric Works" (Mar. 1, 2007)
Kouji Tsuji and Jiro Hashizume (Matsushita Electric Works), Presented at The Second TRIZ Symposium in Japan Held by the Collaborative Board of TRIZ Promoters and Users in Japan, on Aug. 31 - Sept. 2, 2006, at Pana-Hills Osaka, Suita, Osaka.
[After holding in-house 2-day USIT training seminars conducted by Toru Nakagawa three times, the two authors have been conducting 2-day USIT workshops in their company. The paper reported the results of 14 such workshops performed on the projects in the fields of mechanical (6 cases), electrical and IT (5 cases), and chemical and biological (3 cases). In each workshop, five-or-so engineers were guided along the USIT procedure by the authors and generated 27 ideas in average during the 2-day group practice. 92 % of the participants of the workshops evaluated the USIT method worthy of recommending to other engineers. Thus the authors have established a good scheme of actual practice of applying/penetrating USIT. Nakagawa's introduction written in the Personal Report of TRIZ Symposium in Japan, 2006

TRIZ Papers: "Theory of Resolving Differences: A Collection of Papers Written by Toshio Takahara (2003-2007) with Annotated Bibliography" (Mar. 30, 2008)
Toshio Takahara, Dec. 27, 2007
[This page contains all the 14 papers published by Toshio Takahara for these five years and a brief guide to these papers. The 'Difference' stands for the gap between the reality and what we want or what should be. Recognition of such Differences and trials of resolving them are the fundamentals in human activities, the Author understands. Such human activities take various forms and phases, including goal setting, problem recognition, designing, problem solving, etc. The Author is trying to present a unified method of understanding and representing the whole process of Resolving Differences. Behind the Author's unique and hence not-easy-to-adopt terminologies, I realized the clarity in the representations and the significance of the theory last October when I was reviewing his paper

Keynote (2) of First TRIZ Symposium in Japan: "TRIZ Critical SWOT: Systematic Innovation Today and Tomorrow" (Sept. 20, 2005)
Darrell Mann (Systematic Innovation Ltd. UK), Keynote Speech (2) presented at the First TRIZ Symposium in Japan, held by 'Japan TRIZ CB' on Sept. 1-3, 2005, at Laforet Shuzenji, Izu.
[TRIZ is approaching a critical point in its history, either becoming widely adapted in the world or shrinking into cult-like obscurity. Thus, in this presentation, the strengths, weaknesses, oportunities, and threats of TRIZ are examined. The biggest threats for TRIZ is that the people who follow the tradition of TRIZ would not help make TRIZ adaptable to the world. The isolation of TRIZ from academia and from policy making must be overcome. On the other hand, many big (technical) problems for the human kind are waiting to be solved; these are the big opportunities for TRIZ.]
Keynote (1) of First TRIZ Symposium in Japan: "A New Generation of TRIZ" (Sept. 20, 2005)
Toru Nakagawa (Osaka Gakuin Univ.), Keynote Speech (1) presented at the First TRIZ Symposium in Japan, held by 'Japan TRIZ CB' on Sept. 1-3, 2005, at Laforet Shuzenji, Izu.
[Along the progress in penetration and understanding of TRIZ, it has become clear that the confuzing situation of TRIZ overall procedure and the missing in establishing the overall structure of TRIZ are the root causes for the obscurity in TRIZ for novices. It is necessary to extract the essences of TRIZ, unify and integrate them, and re-structure them in a way easy to understand and effective to apply. This is the process for creating a new generation of TRIZ. The present author believes that USIT has been developed towards this goal. In particular, the Six-Box Scheme in USIT provides a new paradigm for creative problem solving.]
Introductory/Series : "TRIZ Up-to-Date (Part 5) Overall Process of Problem Solving in TRIZ/USIT" (Aug. 28, 2005)
Toru Nakagawa (Osaka Gakuin Univ.), "Nikkei Monozukuri" (Nikkei BP), Jul. 2005, pp. 100-103.
[Part 5 of the series of introductory articles published in the monthly Journal, "Manufacturing" published by Nikkei BP. The reason for rather slow penetration of TRIZ is attributable to the fact that TRIZ, having so many individual tools, has not well established the overall process of problem solving and more deeply to the fact that it has not established the overall structure (representable in data flow diagrams) of problem solving. USIT established a clear oveall structure and a clear overall procedure. The Six-Box Scheme in USIT provides a new paradigm for creative problem solving. ]
