Editor's Note (Toru Nakagawa, Jul. 8, 2009)
This paper was presented at the Fourth TRIZ Symposium in Japan, 2008
, which was held last September by 'Japan TRIZ Society, NPO'.
Japan TRIZ Society has posted the presentation files (in Japanese) of all the Contributed Presentations in the 'Members-Only' area of its Official Web site (http://www.triz-japan.org/ ) in PDF on July 1, 2009. Files in English are going to be posted in a similar way.
The present site, "TRIZ Home Page in Japan", on the other hand, is going to post several selected Contributed Presentations publicly, under the desire & permisson by the Authors. Presentation slides of them will be posted in PDF, with the policy of updating prohibited, copying and printing permitted.
Authors' Abtract is posted in this page, and the presentation slides (4 slides only in this case) are also posted in English in PDF
. I also post my introduction to this presentation, in the form of an excerpt of my "Personal Report of Japan TRIZ Symposium 2008"
.

Creative Problem Solving Process Where We Use Only 12 TRIZ Principles: Generating Ideas and Combining Ideas
Creativity Study Group
Hiroto Hayashi (IWEL Co. / Iteq International Co.),
Nobuhide Matsuda (Matsushita Electric Industrial Co., Ltd.),
Hiroshi Kamijyo (Iteq International Co. / IWEL Co.), et al.The idea creation can be performed by utilizing effectively the "Invention Principles" of TRIZ which is one of the creative techniques in the thinking process of invention. By choosing "The 12 Principles" from "The 40 Principles" of TRIZ, it is not for a radical improvement which needs the large-scale idea but can realize idea creation which is excellent for a short time by narrowing down to "improvement and an improvement" of the existing system currently faced on daily business. The thinking process of the 12 Principles consists of "problem setup", "goal setting", "investigation of the cause", "creation of ideas" and "combination of ideas, evaluation and selection". Work in each stage is shown using problem solving of "People are not injured even if they are inserted by an automatic pivoted door" as an example.

Personal Report of The Fourth TRIZ Symposium in Japan, 2008

Creativity Study Group: Hiroto Hayashi (IWEL Co. / Iteq International Co.), Nobuhide Matsuda (Matsushita Electric Industrial Co., Ltd.), Hiroshi Kamijyo (Iteq International Co. / IWEL Co.) [O-15 #36] gave an oral presentation with the title of "Idea Process using only 12 Principles". The same Group made two more Poster presentations. They are: H. Kamijyo, N. Matsuda, and H. Hayashi [P-B5 #37] on "Idea Process using only 12 Principles: Function Components Deployment and Find Primary Cause"; and N. Matsuda, H. Kamijyo, H. Hayashi [P-C5 #33] on "Creative Problem Solving Process Where We Use Only 12 TRIZ Principles: Generating Ideas and Combining Ideas".
This Study Group has also about 25 voluntary members coming from different industries. The Group was formed spontaneously in 2006 by the users (or clients) of consultants, Mr. Hiroto Hayashi and Mr. Hiroshi Kamijo. They had meetings once a month, from 10:00 to 17:00 on Saturdays, and made group practices of TRIZ together. Most of the members are located near Osaka, but some come from Tokyo, Nagoya, Hiroshima, and Fukuoka (with their private money). Several active members in this Group are also the members of the TRIZ Study Group in the Japan VE Association mentioned above. I did not know about this group until recently when I was asked to review the drafts of their new TRIZ textbook (published in May 2008). Their motive is to make TRIZ easy and yet effective to apply real problems.
The problem solving process they have established and published in the textbook is outlined in the slide (see right). The process consists of two parts, i.e. Problem analysis and Problem solving. The Authors presented these steps in detail by using the whole process of a case study.
Their case study is the safety problem of a revolving door. About a year ago we heard sad news that a child was caught between a revolving door and the external wall, and was killed.
The first step is to set up the problem. After setting the problem they discuss the problem in various angles. They draw sketches of the problem situations, to understand the space and time relationships, to understand the functions of components of the system, and (particularly in this problem) degrees of injuries in various cases.
On these bases, they go ahead to set up the Goal of this case study.
Next step is to reveal the underlying causes. Their method here is called "Naze Naze Tenkai" in Japanese ("Why, Why Deployment", or "Root Cause Analysis"). Here shows its detailed process, i.e., executing Brain Storming of the causes, extracting causes further from the view point of problem, and from the view point of wishes, then finally selecting the most significant one.
In the step of Idea generation, the logic of ARIZ is used to select TRIZ Principles to be used as suggestions. The Study Group selected only 12 Inventive Principles which are most often used. They use a picture book containing a lot of illustrated examples of applying these 12 Principles. Thus they generate a large number of ideas and draw their sketches.
In the next step they further try to combine ideas and then to evaluate the ideas from several view points of Quality, Cost, and Delivery.
This Study Group has already established the whole process of problem solving as described here, and is trying to apply it to different problems in order to refine the method.
