The 6th Japan TRIZ Symposium 2010
Held by Japan TRIZ Society on Sept. 9-11, 2010
at Kanagawa Institute of Technology, Atsugi, Kanagawa, Japan

Abstract

The problem solving that uses the TRIZ method is effective for the improvement of the product and the technology. In addition, it is effective for the problem solving in the research and development stage without the experience enough.

However, it starts solving it only by experiencing his/her specialized field for the person who doesn't know knowledge and the use method of TRIZ. Cases and the explanations of TRIZ that offers them easiness to understand and sympathy are requested.

However, it is not easy. In the research and development, the specialized field of anyone is narrow. On the other hand, the entire section takes up various topics widely.

An approach which offered them an attractive explanation has begun. An industry system newspaper that is familiar with latest information is used. Development articles on the corresponding technology are extracted. Next, it arranges it adding the analysis with TRIZ. Case and explanations of TRIZ are made.

Those who research and develop it learn cases and explanations of their own specialized fields.

It introduces understanding by a current content of execution and a continuous approach.

Hisataka Izawa, Narumi Nagase, and Shusei Kunitomo (Sony Corp.) [J12, O-15] gave an Oral presentation with the title of "Approach of Reverse TRIZ Using Industry Newspaper Articles".  I missed attending at this presentation.  The presentation won (one of the four) 'Best presentation for me' Award by the voting of the Symposium participants.  The PDF files of the presentation slides are posted publicly in the Official Web site of Japan TRIZ Society.  I will quote the Authors' Abstract first:

The problem solving that uses the TRIZ method is effective for the improvement of the product and the technology. In addition, it is effective for the problem solving in the research and development stage without the experience enough.
However, it starts solving it only by experiencing his/her specialized field for the person who doesn't know knowledge and the use method of TRIZ. Cases and the explanations of TRIZ that offers them easiness to understand and sympathy are requested.
However, it is not easy. In the research and development, the specialized field of anyone is narrow. On the other hand, the entire section takes up various topics widely.

An approach which offered them an attractive explanation has begun. An industry system newspaper that is familiar with latest information is used. Development articles on the corresponding technology are extracted. Next, it arranges it adding the analysis with TRIZ. Case and explanations of TRIZ are made.
Those who research and develop it learn cases and explanations of their own specialized fields.
It introduces understanding by a current content of execution and a continuous approach.

The Authors have been working for many years for promoting TRIZ in their company.  As usual for such in-company promoters, they gave training seminars and coached projects with TRIZ.  However, they felt much difficulty in penetrating TRIZ into their R&D people.  The slide (right) shows their trials for making TRIZ easier to understand. Trying to explain TRIZ in a general and consistent manner is possible in some fields like mechanical engineering, but difficult in other fields like materials, systems, software, etc. Trying to explain TRIZ more specifically by using published case studies and patents is nice, but such information source is rather limited.  Thus, in the present work, the Authors introduced the way of explaining TRIZ by use of the reverse analyses of new products/services reported in industry newspapers.   [*** Some parts of the slides in English may not be clear enough for you at first, I am afraid.  But please understand the Authors' intentions from the overall contexts of the presentation.]

The following slides (below-left and below-right) demonstrate how the newspaper articles are analyzed in the eyes of TRIZ.  The Authors explain their analysis method in the framework of the Four-Box Scheme.  Reading each article, they first try to understand the specific problem of the case and to understand what difficulty/trade-off problem/contradiction the inventors identified in their process of new product development.  Then the Authors try to understand the essence of the inventor's new solutions in terms of the 40 Inventive Principles in TRIZ.  Such a process of reverse analysis of inventions is well known and, so to speak, traditional in TRIZ since Altshuller's original work.

 

Such analyses of newspaper articles can be accumulated to build up the examples of applying TRIZ Inventive Principles.  In the slide (below-right), number of articles related to each Inventive Principle is demonstrated. 

  

As shown in the slide (below-left), the fields of the newspaper articles the Authors have analyzed are distributed widely.  Thus the Authors have developed a rich knowledge base of nice application examples of the Inventive Principles in these various fields of industry (slide (below-right)). 

  

The third process of problem solving in the TRIZ Four-Box Scheme (slide (right)) is the Realization of Generic Solution (i.e. the Principle's suggestion) into Specific Solution (i.e. the new product/service).  Since the newspaper articles describe new products/services of much interest in detail, we can have a nice collection of examples of results of this Realization step, the Authors say.   The slide (right) mentions the benefits of the reverse analysis with TRIZ.  We can understand many real success cases from the eyes of TRIZ. 

Case studies of such reverse TRIZ analyses have been regularly posted in their intranet Web site for promoting TRIZ.  Such case studies have been used also in the seminars for training idea generation capabilities.  The scheme is shown in the slide (right).  On the basis of the TRIZ reverse analysis of a newspaper article, a problem is set up as a training case study.  Groups of trainee engineers solve the problem by using TRIZ, typically with the Contradiction Matrix and Inventive Problems, to generate multiple of solutions.  The trainees' ideas are checked with the  inventor's solution.  It is also interesting to think further proactively about the problem to generate more ideas using unused TRIZ Principles. 

The Authors also applied another TRIZ way of understanding the essence of the invention reported in the newspaper article.  They used the Trends of Evolution of Technical Systems (slide (below-left)).  Reading the articles, they try to understand the essence of the inventions in terms of the Trends of Evolution, which may be referred in textbooks (e.g., Darrell Mann's HOSI) or in software tools (e.g., GFIN) (slide (below-left)).

  

The Authors mentioned that they also analyzed a number of patent journals (slide (below-left)).  The analysis work has been done in collaboration in the Intellectual Property Creation Study Group of Japan TRIZ Society, and was reported by K. Hasegawa et al.  in the Symposium. The present Authors, however, have concluded that articles in industry newspapers are superior to the patent journals as the documents to be reversely analyzed with TRIZ.  The slide (below-right) describes their reasoning.  Among these points, most important is the familiarity of or even sensational interest in the new products for both common engineers and TRIZ promoters, I feel.  Furthermore, such new products are publicly described in detail in various information sources, other than the newspaper article, and are already proved to be success in technology. 

 

In the slide (below-left), the Authors have reported the good effects of reverse TRIZ study of newspaper articles on the skill of engineers and promoters.  As you see in these items, the reverse TRIZ study has given (and has the possibilities to give more widely) good influences on the persons who make the analysis and on many more persons who read and learn the results.  The slide (below-right) is the summary of presentation by the Authors.  As written at the bottom of this slide, the Authors demonstrated several real examples of their reverse TRIZ analysis during the presentation.  [They are not included in the presentation file of the Proceedings. ]

  

[*** This is a nice way of studying, training, penetrating, and promoting TRIZ, I realized.  I recall the Keynote Lecture by Mahmoud Karimi; every week in a newspaper he wrote a column of introducing interesting products/services/ideas from the eyes of TRIZ.  Mr. Karimi published his work in newspapers/magazines, while the present Authors posted and showed their work in their company.  However, the contents of work may not be so much different in these two activities, I suppose.  We can also carry out similar activities in our own place, e.g., in our companies, in our schools, in our joint working teams, in our Web sites, etc. ]
