Editor's Note (Toru Nakagawa, Jan. 27, 2008)

The paper posted here was originally presented last August at The Third TRIZ Symposium in Japan held at TOSHIBA Kenshu Center, Yokohama.  The paper was presented in the poster session on the second day afternoon, and attracted a lot of visitors.  The "Wisdom Cards" are charmingly designed 40 cards of TRIZ Inventive Principles, to be PLAYED with either personally or in a group for generating ideas.

This page in English contains the followings:

[1] Abstract

Challenge to Increase TRIZ Users:
Original Tool Development at Miyagi TRIZ Society  "Wisdom Cards"

Rikie Ishii (Dunamis Co., Ltd. / NEDO) and
Toshinori Ito (Industrial Technology Institute, Miyagi Prefectural Government)

After a TRIZ seminar, we have found that the seminar participants have met difficulties in explaining their fellows how TRIZ promote the idea creation work.  Thus, we started to develop a tool which can be used to generate creative ideas in an easy and pleasant manner, just like playing a card game.  We will report the contents of the tool and its effects.


[2] Introduction & Review of the Presentation (Toru Nakagawa (OGU), Nov. 14, 2007)

Excerpt from Nakagawa's 'Personal Report of Japan TRIZ Symposium 2007' (posted on Nov. 18, 2007). 

Rikie Ishii (Dunamis Co., Ltd./ NEDO), Toshinori Ito (Industrial Technology Institute, Miyagi Prefectural Government) [37] gave an interesting poster presentation with the title of "Challenge to TRIZ User Increase: Original Tool Development of Miyagi TRIZ Society".  This presentation was done as the report of the activities of 'Miyagi TRIZ Society'. Miyagi Prefecture is one of the 47 prefectural units in Japan, located in the northern part of Honshu with its prefectural capital Sendai City. The two young authors are collaborating actively to promote innovations in the area.  Rikie Ishii has spun off a company and is now working as a NEDO fellow (i.e., persons receiving a fellowship from the governmental organization NEDO (= New Energy and Industrial Technology Development Organization)  and working for promoting innovative activities) in a small venture company, Dunamis Co.  He and Toshinori Ito, an official of the prefectural institute, established a study group 'Miyagi TRIZ Society' for penetrating innovation methods especially TRIZ into local industries.  They call their group 'Mi-TRIZ' in short, which sounds like a Japanese word 'MITORIZU' meaning a design plan or a map.  I will cite their Abstract slide first:

The Authors tried to make the TRIZ 40 Inventive Principles into 40 small cards easy to understand and stimulative to generate new ideas for ordinary engineers.  They have made the 40 cards as follows, with the name of 'Wisdom Cards'.  The cards are not translated into English yet.  So I will show you my translation at the right column in order to convey the flavor of these cards to you.  [Note (Feb. 5, 2008, T. Nakagawa):  Last November I showed only 20 cards in English.  Now, all the 40 'Wisdom Cards' are posted here in English translation by Toru Nakagawa under the Authors' approval.]

1. Divide it.

17. Use the direction perpendicular to the plane.
18. Make it vibrated.
19. Do it repeatedly.
20. Continue the good work.

 

21. Finish it in a very short time.
22. Extract something good from the bad situation.
23. Feed back the information.
24. Use something strong at the contact place.
25. Arrange things to do good for themselves.

26. Use copies of it.
27. Use many of cheap short-living things.
28. Move it without touching.
29. Use pressure effects of water or air.
30. Use a flexible cover.

31. Introduce something adhesive.
32. Change the color.
33. Match the qualities.
34. Stop getting out or put it back.
35. Change the temperature, flexibility, etc.

36. Change a solid into a gas or a liquid.
37. Expand it with heat.
38. Use more concentrated one.
39.  Fill the space with a non-reactive thing.
40.  Use something combined.

The Authors suggests three ways of using the Wisdom Cards:

(a) Using the Wisdom Cards personally:  With a problem to solve in mind, turn to see the Card one by one (maybe for 10 seconds per Card) and try to find a solution(s) inspired with the Card. 

(b) Using in a Group for solving a problem: Distribute all the Wisdom Cards to the group members (2 to 8 members).  Members think of ideas seeing the Cards for 3 minutes, and write them down in Post-it Notes.  Then the members explain his/her ideas (up to 3) for 1 minute by turn, showing the stimulating Wisdom Card. Other members, if inspired, should write down the ideas in the Post-it Notes.  Such derivative ideas should be explained at an early timing, not necessarily keeping the turn. 

(c) Use in a Group as a game for solving a practice problem:  Set a theme of problem first.  Put all the Wisdom Cards with face down at the center of the table.  One of the members takes the top Card, reads it aloud, and tries to think of a solution idea inspired with the Card.  If he/she can tell an idea in 30 seconds, the Card is put in his/her stack; if not, the Card has to be put back at the center. Then the next member takes the next Card, by turn.  In 20 minutes the game ends.  The member who has obtained the largest number of Cards wins the game.    

The Authors have used the Wisdom Cards in various opportunities and have got nice and encouraging results.  People often say that generating ideas in this manner was hard but very interesting, the Authors write.

*** This tool of Wisdom Cards is simple and cheap but very interesting.  The trials made by the Mi-TRIZ are encouraging much new trials in companies, schools, and voluntary groups.
