-- TRIZ Books (Announcement of Publication): Japanese Edition of Darrell Mann: "Matrix 2010" -- Publication Announcement (Plan) (Jan. 22, 2012)

Translated by Toru Nakagawa (OGU), (to be) Published by Sozo Kaihatsu Initiative (SKI), Feb. 2012 (plan)
In 2000, Darrell Mann and Simon Dewulf (CREAX) initiated a big research project of analyzing all the US patents granted since 1985 for revising TRIZ knowledge bases.  One of their results was "Matrix 2003" which was an entire update of the Altshuller's Contradiction Matrix.  Darrell Mann (Systematic Innovation) has kept the project's activities and recently published an up-to-date edition "Matrix 2010", for maintaining higher-than-90% appropriateness of the Inventive Principles suggested by the Matrix.  He says they have analyzed more than 3 million patents so far.  The number of parameters has increased from 39 to 48 to 50, and the number of suggested principles in each cell is now up to 9 in comparison to max 4 in the original Matrix.  Once you understand the great vision of Contradiction Matrix by Altshuller, why don't you utilize its up-to-date edition "Matrix 2010".  

-- TRIZ Forum: Contributed article: From Encountering TRIZ to Deeper Understanding (My TRIZ Learning History): Towards a Unified Methodology of Problem Solving for Resolving Various Contradictions (Youichi Hasegawa) (Dec. 5, 2011)

Nowadays, especially after the disaster of earthquake, tsunami, and nuclear plant accident, we have many and complex contradictions in Japan in its social, economical, and political aspects.  For solving such contradictions, methodologies for problem solving should be penetrated and applied widely in some unified and simple-to-learn forms of techniques, Youichi Hasegawa says.  For a step toward such a unified methodology, Hasegawa has contributed to this Web site an article which introduces his personal history of learning TRIZ.  He encountered TRIZ and USIT in 2006 through his colleagues in his company and learned various TRIZ references, especially the ones posted and introduced in "TRIZ Home Page in Japan", for himself step by step.  Reading such references, he tried to understand them with digesting and examining and to incorporate them in his understanding of problem-solving methodologies.  He now has a hope of unifying currently-different methodologies, e.g., QFD, TRIZ/USIT, TOC, Hatamura's method, Breakthrough Thinking, etc., into a much simpler and universal one.  This article is an excellent case study of learning TRIZ/USIT step by step and obtaining a much wider vision of problem-solving methdology.  We thank Youichi Hasegawa for his contribution.  In Japanese, only.

-- TRIZ Forum: Interview: First-time Experience of Participating and Presenting in English at International Conference, ETRIA TFC 2011, Ireland (Ayano Sato (Shibaura Inst. Tech.); Interviewer: Toru Nakagawa) (Dec. 5, 2011)

Ms. Ayano Sato, 2nd year Graduate Student, attended at ETRIA TFC 2011 and gave a very nice presentation.  So Nakagawa interviewed her just after her presentation and also communicated with her via emails later.  She says:  She wanted (without being pushed) to give the presentation.  She used to be very shy and did not like studying English language, but at her 2nd year of high school her parents arranged her to go and study at an English language school in USA for 2 weeks.  During the stay she realized the necessity of communicating in English, and started to learn English for herself.  She met much difficulty to pass the review process of TFC.  The keyword 'Kando' in Japanese was especially difficult for her to present to the reviewer and to the audience.  ('Kando' is a very deep and strong impression which moves the person later even for years.)  When a number of audience said 'Nice talk!' to her, she felt much relieved and delighted.  She found people at TFC talked about TRIZ much positively and widely than she learned so far in Japan, and she was impressed by aggressive TRIZ activities in Korea. -- I wish that Ayano's young and fresh heart/mind gives 'Kando' to readers of this TRIZ site in Japan.  (Only in Japanese.)

-- TRIZ Cae Study: Problem Solving in Everyday Life: On Methods and Tools for Weeding (or Removing Weeds) (Takahisa Miyake, Toru Nakagawa (Osaka Gakuin Univ.)) (Nov. 18, 2011)

Presented at 7th TRIZ Symposium in Japan (Sept. 8-10, 2011, Yokohama), and also at ETRIA TRIZ Future Conference (Nov. 2-4, 2011, Dublin, Ireland).  Extended Abstract: , Presentation slides
'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.

A brief but valuable report from mainland China:  'TRIZ was inroduced into China about 1998, but was known to only limited number of academic people for next 9 years.  In 2007, the TRIZ situation has greatly changed when the Ministry of Science and Technolgy recognized TRIZ as the Innovation Method and started its promotion actively.  Two provinces, Heilongjiang and Sichuan, became the 'Pilot Provinces' of innovation methods, and Innovation Method Society (IMS) was established under the Ministry for the purpose of research, development, and penetration of Innovation Method (i.e., TRIZ).  At least three conferences/seminars in China are operated for high level communications on TRIZ, though not yet international.'  PDF in English , in Chinese , and in Japanese translation .

Among the presentations at the 6th Japan TRIZ Symposium last year, 24 presentations have been selected and posted pubicly in this Web site both in English and in Japanese.  Links to such pages are inserted in the tables of presentations in my "Personal Reports". 

** TRIZ papers:  Selected 7 Japanese Papers presented at The 6th Japan TRIZ Symposium 2010   (Sept. 25, 2011)

Among the papers presented last year at the 6th Japan TRIZ Symposium 2010, the following 7 papers by Japanese authors are selected and posted here, for the purpose of wider circulation. Each page contains (Extended) Abstract, PDF file of the presentation slides, and Nakagawa's introduction excerpt from his "Personal Report" of the Symposium. 

-- Application of USIT to Useful Paper Fastener (MPUF USIT/TRIZ Study Group: Kouichi Nakamura et al.)   (Sept. 25, 2011)

A study group of engineers voluntary coming from different industries worked to develop various concepts for improving simple paper fasteners. They used their 'USIT Workbook' step by step for proving its effectiveness. Processes of analyses and idea generation are recorded fully with a large number of illustrations.  PDF of presentation slides .

-- Guiding Noise and Vibration Design along General TRIZ Process by Misunderstanding Case List (Masao Ishihama (Kanagawa Inst. of Tech.))   (Sept. 25, 2011)

The Author previously developed a TRIZ-based standard process for guiding engineers to work on the Noise and Vibration Design, especially for vehicles. However, in addition to such a normal guidance, he has found the importance of showing them negative lessons, i.e., cases of misunderstanding. So he built up a knowledgebase of misunderstanding cases of Noise and Vibration design.  PDF of presentation slides

-- Concept Design of a Child-Seat by TRIZ Style Problem Identification (2) (Minami Hamada (Kanagawa Inst. of Tech.))   (Sept. 25, 2011)

The Author's previous idea of 'swing child seat on a spherical swivel' had a problem of no control and no damping of motion. Using TRIZ tools she found solutions of introducing an oval swivel to suppress yaw motion and a magnet for damping with the Eddy current. PDF of Poster Introduction slides , Poster slides , Nakagawa's Introduction .

-- Japan-oriented Creative Monozukuri (manufacturing and production) with TRIZ (Takuo Maeda (Takumi System Architects, Ltd.))   (Sept. 25, 2011)

This is an intensive and bird-view presentation on the future directions of Japanese industry, especially software industry, with a keen sense of crisis. The Author proposes a basic framework of monozukuri and has strived to integrated the TRIZ/USIT thinking into the whole process of business and technology innovation. He recently made "Workbook to Innovate Business and Technology". Onto the workbook, users write down their specific thoughts/ideas step by step under the guidance of the Workbook.  PDF of presentation slides .

-- An Application of TRIZ Way of Thinking and Its Tools to Develop a New Business Model (Japan TRIZ Society Business & Management TRIZ Application Sub-Team: Ikuo Yoshizawa et al.)   (Sept. 25, 2011)

This is the third report of the Study Group.  Selecting a specific case of 'Large-Screen Television System' as an example, the Authors developed and discussed how to develop a new business model.  They focus on the phase of 'drawing the scheme' (or building the viewpoints for defining/differentiating) of the new business model. PDF of Poster Introduction slides , Poster slides ; Nakagawa's Inroduction.

-- A Practical-type Approach Applying TRIZ to the Mind Field - Toward the Establishment of a TRIZ Mind Training - (Hideto Sanjou (DOCOMO Systems), Yukie Hanaoka (Wisdom, Inc.))   (Sept. 25, 2011)

The Authors working for 'Mind Training', e.g., employee training in companies, eliminating individual’s worries, etc., have met TRIZ and incorporated it well. They have rephrased TRIZ 40 Inventive Principles into Mind Principles, and applied them to the training of people to overcome their psychological inertia.  PDF of presentation slides ; Nakagawa's Introduction .

-- The Ideal of TRIZ: TRIZ as the Way of Life? Part 2 (Toshio Takahara)   (Sept. 25, 2011)

This is a philosophical and sophisticated paper. The Author wants to explain/describe everything not only in technology, but also in human and society world, in a systematic manner. He expanded the concept of 'Objects' to be 'Everything we can recognize', thus containing not only substances, systems, ideas, etc. but also movements, changes, processes, etc. With these widened concepts, he tries to describe the 'Ideal of TRIZ' in a formal way as the transformation from the problem situations to the solutions. He suggests the importance of Radical Thinking for Enumeration as the basis for theoretical thinking. A much elaborated paper, I believe.

Japan TRIZ Society has posted the presentation slides of the four papers publicly in its Official Web site since last December.  For the purpose of wider circulation, I have prepared individual pages of these papers both in English and in Japanese under the permissions of the authors.  Each page contains (Extended) Abstract, PDF file of the presentation slides, and Nakagawa's introduction excerpt from his "Personal Report" of the Symposium. 

-- Approach of Reverse TRIZ Using Industry System Newspaper Articles (Hisataka Izawa, Narumi Nagase, Shusei Kunitomo (SONY))   (Sept. 25, 2011)

For promoting TRIZ in the company, the Authors found the up-to-date technological/business articles in industry-oriented newspapers are useful. They reviewed and analyzed such articles from the TRIZ viewpoint and introduced/distributed them regularly with the intranet Web site and in training seminars. PDF of presentation slides ; Nakagawa's Introducton .

-- Let's think in Little People’s and Person's Worlds! : A Summer Homework by Son and Father with TRIZ (2nd Time) (Kai Miyanishi (Kenroku Junior High School /Son), Katsuya Miyanishi ( /Father))   (Sept. 25, 2011)

This presentation is Miyanishi Family's 2nd report, done by Kai (13 years old) with the guidance by his Father. They try to understand how a screw nail is magnetized with a magnet, in the words familiar for the son; thus they used the personalization, or animation. Human relationships, such as getting good friends with or giving an influence on other, are considered as the hints for designing physical experiments.  PDF of presentation slides ; Nakagawa's Introducton .

-- Practice of Creative Thinking through TRIZ Mind Cards - Everywhere with Essence of TRIZ - (Yukie Hanaoka (Wisdom, Inc.), Hideto Sanjou (DOCOMO Systems))   (Sept. 25, 2011)

This is an extension of the Oral presentation by H. Sanjou and Y. Hanaoka .  Combining 40 Mind Principles (coming from TRIZ, as shown in the oral presentation) and 12 patterns of mental conflict, the Authors made a set of 'Mind Cards'.  Using them just like playing cards, the Authors have built a new model of Mind Training for the trainees to help themselves overcome their mental conflicts.

This paper is an excellent result of discussions by six coauthors having quite different specialties besides TRIZ. Their main framework adopted here is the 'Expansion of Thoughts Diagram' well-known in the field of design engineering. They have placed the role of the TRIZ Contradiction methods in this framework. They have proposed to divide the Contradiction-Matrix parameters into two groups; one group to be considered in relation to mechanism, and the other structure. Thus, they have derived two Revised Contradiction Matrices, neglecting the cross terms between the parameter groups.  PDF of presentation slides ; PDF of full paper ; Nakagawa's Introduction

-- TRIZ Case Study: Concept Development of a Variable Compression Ratio Engine Using TRIZ (Hong-Wook Lee, Won Gyu Kim, Myung Rae Cho, Jin Woo Cho, Sang Hee Lee (Hyundai-Kia Motor Company, Korea)) (Sept. 19, 2011)

An excellent record of TRIZ thinking for developing improved solution concepts further and further.  The Authors learned the merits of Variable Compression Ratio (VCR) Engines, which are of course patent protected. Thus they circumvented the patents by use of Trimming, strengthen the resultant idea with 'Antidote', solved a secondary problem with ARIZ, and extended the concept further with the use of Function oriented search.  PDF of presentation slides ,  

-- TRIZ Case Study: Real-Time and Realistic 3D Facial Expression Cloning (Jung-Bae Kim, Youngkyoo Hwang, Won-Chul Bang and James D.K. Kim (Samsung Electronics, Korea))   (Sept. 19, 2011)

The Authors wanted to develop a software method for cloning the user's facial expression vividly onto his/her avatar in the virtual world. Two methods were known: precise Motion-capture method uses many markers and is expensive; while vision-based method is convenient without markers but in precise. The Authors' solution is to separate various feature parameters by their nature. Parameters different for each user are measured by vision and fixed beforehand, while the parameters dependent on time for a user are traced real time by the vision method. This solution is cheap, convenient, and precise.  PDF of presentation slides ,

-- TRIZ paper (Keynote): TRIZ Activities in Iran: Transfer to a new nationwide paradigm by TRIZ application and promotion (Mahmoud Karimi and Sara Salimi (Iranian Institute of Innovation & Technological Studies (IIITS), Iran)) (Sept. 19, 2011)

Mahmoud Karimi got interested in TRIZ around 1999.  In 2004 he started publishing a column on TRIZ and creativity every week in a newspaper and also in a weekly magazine.  IIITS made a TV lecture series of 5 volumes (35 min. each) and broadcast them several times.  Furthermore, since 2007, he has broadcast live TV Talk Shows more than 160 times (30 min. each) on a few TV channels.  It is really amazing that TRIZ is now widely known among intellectual people in Iran!! Thus he talks about 'transfer to a new nationwide paradigm by TRIZ application and promotion'.  Presentation slides in PDF

-- TRIZ paper (Keynote): General Theory on Powerful Thinking (OTSM): Digest of Evolution, Theoretical Background, Tools for Practice and Some Domain of Application (Nikolai Khomenko (Insight Technologies Lab, Canada)) (Sept. 19, 2011)

OTSM was originally envisioned by Altshuller in mid 1970s and has been developed by Nikolai Khomenko since mid 1980s for extending TRIZ out of technology area into a general, area-free theory for developing tools of solving non-typical problems creatively. Khomenko's lecture summarizing his 25 years of research is introduced here with a clear framework of OTSM: (a) Key problems for OTSM, (b) Axioms in OTSM, (c) Main models of OTSM, and (d) OTSM tools.  In the current stage of OTSM, complex and large-scale problems can be handled with OTSM-TRIZ Problem Flow Network (PFN) approach, Khomenko says. He also discussed about the education of creativity.  Presentation slides in PDF
