 Innovation Paper:  Rethinking Innovation (The Blue LED case and Paradigm Disruptive Innovation) (Eiichi Yamaguchi (Doshisha Univ.; currently: Kyoto Univ.)  (Dec. 10, 2014)

Professor Yamaguchi is the author of "FUKUSHIMA Report', posted here in Sept. 2013 .   In October this year, I met him for the first time at ICSTI2014 and impressed with his presentation on innovation.  So I read his book "Innovation -- Paradigm Disruptions and Fields of Resonance" (NTT Press, 2006) (in Japanese).  He investigated the cases of innovation of transistors and blue LEDs and discussed about the structure of innovations.  He argues that the case of LED innovation (and many others) is not the type of Christensen's Disruptive Innovation (of decreasing the performance for some other needs/purposes) but the type of Paradigm-Disruptive Innovation (by disrupting/changing the basic/physical paradigm).  He discusses how such paradigm change can be achieved, and why big excellent companies often fail in front of such a paradigm change. On my request he kindly sent me his two papers, which are summaries of his book and were published in Japanese (2004) and in English (2006), and permits me to repost them here publicly. 
Tonight (Dec. 10, 2014), three Japanese researchers, Professor Isamu Akasaki, Professor Hiroshi Amano, and Professor Shuji Nakamura are to be jointly awarded the Nobel Prize in Physics 2014 "for the invention of efficient blue light-emitting diodes which has enabled bright and energy-saving white light sources".  Congratulations!  -- I am very happy to repost Professor Yamaguchi's paper here now, with which we can learn how the Nobel Prize awarded LED innovation was achieved and how we would be able to contribute to future innovations. 

 TRIZ Forum: Conference Report (30) Personal Report of The 10th TRIZ Symposium in Japan, 2014 (Sept. 11-12, 2014, Tokyo)(Toru Nakagawa (OGU)) (2014.11.27) 

The 10th Japan TRIZ Symposium 2014 was held last September by Japan TRIZ Society. The Symposium for 2 days had 135 participants in total (mostly from industries, and some from academia; 36% participated for the first time; from overseas: 2 invited speakers + about 3(?) participants). Invited talks: Keynote lecture by Anatoly Guin, Special Invited lecture by Shin Taguchi, and Tutorial 1. 27 Contributed presentation (including 22 oral + 5 poster presentations (including 1 from overseas)). The Symposium was organized well, obtained high-level presentations, and had increased number of participants, all showing its big success. The aspect that the contributions from overseas to presentations and participations are quite small need to be improved.
For all the presentations, slides are projected in Japanese and in English in parallel.   Japan TRIZ Society has recently posted the invited talks and 5 award-winning contributed presentations openly in their Official Web site, while all other contributed presntations in the Members-only pages.
For applying TRIZ, a number of industries have suuccessfully adapted TRIZ tools and processes so as to correspond the differences in purposes, characteristics, and fields of the problems and to match with the levels, orientations, available time, etc. of users.   They also request external consultants to guide them using TRIZ tools suitable for and effective in their needs and situations.  Similarly for the integral use of other methods (e.g., QFD, Taguchi method, Kepner-Tregoe method, etc.), they start using them by smoothly linking the essential parts of them.   Apparently TRIZ people in Japan are increasingly interested in applying TRIZ to the problems in software, non-technology, and social fields.   There are also many trials to make the TRIZ tools easy to understand and effective to use.   In these many aspects, we can say that Japanese industries are advancing TRIZ usage and achieving results in the real jobs.
A vivid report was givien by a national college of technology, but almost no report on TRIZ educaion in unversities.
Even though "innovation" is the top-level fashonable keyword in Japan and in the world, we still have not succeeded in introducing TRIZ into national policy and projects, industrial top managements, universities and academia, etc.   This is the most important problem for us TRIZ community. We should think and work harder.

From Japanese readers: The publication of "TRIZ practices and Benefits" book series are appreciated by several readers. Many readers highly evaluated the four Entrance Pages, in their reader-friendly and easy-access nature to many articles strored in the present site.   Mr. T. Maekawa introduced 'What is TRIZ?' to about 300 people in the Tokyo-Yokohama region of Japan QC Association in his News Letter. Several readers communicated me to have started learning TRIZ with the articles in this site.
From readers abroad: I received an inquirely about the situations and possibiities of publishing Japanese Editions of TRIZ books. Mr. A. Shmonov have sent me several times so far on his work of "Computers can invent independently".  The four "Entrance pages" are evaluated highly.  On the 16th Anniversary of "TRIZ Home Page in Japan", many people sent me messages of congratulations and encouragements.  Thanks so much.

-- CrePS/TRIZ/USIT Paper:  General Methodology of Creative Problem Solving & Task Achieving (CrePS): Reorganizing Various Application Cases and Their Methods in the ‘Six-Box Scheme’ (Toru Nakagawa)  (Nov. 7, 2014)

Three papers of the same title but with some adjustments were presented at three conferences: i.e.,  (A) Japan TRIZ Society, 10th TRIZ Symposium in Japan (Sept. 11-12, 2014, at Waseda Univ., Tokyo); (B) Japan Creativity Society, 36th Annual Conference (Oct. 25-26, 2014, SANNO Institute of Management, Tokyo); (C) European TRIZ Association (ETRIA), 14th World TRIZ Future Conference 2014 (Oct. 29-31, 2014, EPFL, Lausanne, Switzerland).  My main message is: "We can establish the General methodology CrePS on the basis of TRIZ/USIT research by reorganizing a wide variety of problem solving methods in the 'Six-Box Scheme'".  The on-going research activities for developing CrePS are: (1) To make course materials of CrePS case studies. (We should just use case studies already published.) (2) To understand different methods (including TRIZ) and to describe them in the framework of CrePS. (3) To relate CrePS to various activities in the 'Real world'. (4) To categorize various purposes of CrePS application, and to recommend concise CrePS processes for each category.  (5) To proliferate the vision of CrePS. -- I wish you to share this vision and collaborate together!
In the English page, the slides presented at ETRIA TFC are posted but not the paper yet until ETRIA's public posting in Elsevier Procedia.  In the Japanese page, the slides (for ETRIA TFC in Japanese translation ) and the paper (for JCS ) are posted.  In addition, the following PDF files are also posted: Paper (for JCS ), Slides (for Japan TRIZ Sympo   , for JCS  , for ETRIA TFC  ).

  -- Editorial:  On the 16th Anniversary of  "TRIZ Home Page in Japan":  (Toru Nakagawa) (Nov.  7, 2014)

This Web site "TRIZ Home Page in Japan" celebrates its 16th Anniversary on Nov. 1 together with readers in Japan and over the world.  This site is to promote the understanding and real usage of TRIZ by openly publishing information and communications related to TRIZ on a not-for-profit basis.  Though I have been operating this site as a volunteer, this site is not a personal site but a public forum to be composed of the contributions by readers, as you see already.  Most pages are published in Japanese and in English in parallel for the purpose of mutual understanding and collaboration between Japanese and overseas TRIZ learners/practitioners.  I envisage that Pubic Web Sites built in different TRIZ Communities will form A Global TRIZ Community with much reduced language barriers .  Since two years ago I have been proposing to establish a General methodology for creative problem solving & task achieving by integrating various creativity methods including TRIZ/USIT .  I am going to widen the scope of this Web site gradually in future.   The number of visits since November 2005 is (on Nov. 4) 212,212 (increasing by about 14,000 for the last 1 year) to the top page in Japanese and 36,711 (increasing by about 3,300) to that in English.  Four Entrance Pages have recently been installed for your easy access to articles.  Readers' contributions either in English or in Japanese are heartily welcome.

Editorial:  'General Index' page has been reorganized and divided into 4 pages (Toru Nakagawa)   (Sept. 25, 2014)  (Oct. 17, 2014)

The General Index provides a large number of categorization tables which contain all the articles posted in the present site for these 16 years since its start.  Each article is shown by the title, the authors, and the date of posting/update, and has links accessible with one clik to its English page as well as its Japanee page.  With the accumulation of articles, the General Index page has become so heavy that I have divided it into four pages.  They are:

General Index  (A) Parent page and Editorial: Guide to the preent site, Index of 'From the Editor' pages 
General Index  (B) References:  References, Links, News and activities, Software tools:  
General Index  (C) Papers:  Papers, Case studies, Technical reports, Introductory articles, Lecture materials, Documents of methodologies:  
General Index  (D) Forum:  Reports of conferences; Book reviews; Communications, discussions, questions, opinions, feedbacks, etc.; Collabo pages:  

Editorial:   Four 'Entrance Pages' to the present site have been built to make this site friendly to different types of readers (Toru Nakagawa)  (Sept. 7; Sept. 25; Oct. 17, 2014)

The top page of this site has been renewed and four 'Entrance Pages' have been introduced. The table cells of 4 different colors are the icons to guide you to the Entrance Page suitable for you depending on your current situations and interests.

In each Entrance Page, I am planning to write some introduction at the top which may stay for some years, and I show a list of selected recommended articles among the articles so far posted in the present site.  Every such article is introduced briefly and is accessible with one click of hyperlink icons.   I believe the present site has become much more friendly for you with these Entrance Pages, which guide you to the real treasury of interesting and useful articles.

*** Editorial (Toru Nakagawa): The General Index page of this site provides the one-click access links of all the articles posted for these 16 years.  Since it becomes so large, I have divided it into the following 4 pages:  (A) Main and Editorial, (B) References (books, links, news, software tools, etc.), (C) Papers (papers, case studies, introductory articles, course materials, etc.), and (D) Forum (conference reports, communications, etc.).  Posted in Japanese, but not ready in English. (Sept. 25, 2014)

*** Editorial (Toru Nakagawa):  For making this Web site familiar & friendly for readers, 4 Entrance Pages have been introduced.  They are accessible from the top page and list selected, many articles with brief introduction and links for one-click access:  Entrance pages (1) for children and highschool students, (2) for students and the general public, (3) for engineers and researchers (new to TRIZ), (4) for practitioners.  Already posted in Japanese , but will be by the end of Septmber in English. (Sept. 7, 2014)  Brief introduction notes are attached to all the articles listed in the 4 Entrance pages.  I am working hard to make the 4 Entrance pages in English before I come to ETRIA TFC 2014 on Oct. 29-31. (Sept. 25, 2014)

Announcement: Publication Announcement of the Japanese Edition: Umakant Mishra's "Treasury of Inventive Ideas for Information Technology & Software - Classified with TRIZ Inventive Principles" (Toru Nakagawa (CrePS Institute)) (Aug. 29, 2014)

Authored by Umakant Mishra (India), Japanese translation by Toru Nakagawa (Supervising translator), Yoshihisa Konishi, Toru Shonai, Masatoshi Hotta, and Takuo Maeda, Published by the CrePS Institute, on Aug. 25, 2014.  Printed Edition: Soft cover, B5 size, 340 pages, 4000 yen + tax, Print-on-Demand at DLmarket site. Downloading Edition: PDF, 2500 yen + tax.
Please see the page of the Series , flyer of the series, and flyer of this volume

This book is principally dedicated to people involved in IT and software, as engineers, researchers, PC users, etc. The author collected about 3000 cases of IT/SW solutions from US patents and other technical sources, and interpreted the essence of their solution ideas, and classified the cases with the viewpoints of the essence of ideas by use of TRIZ 40 Principles.  In each of 40 chapters, meaning of a Principle, benefits and application situations, and various application cases of IT/SW technology/techniques are described to clarify how the solution ideas may be generated from the Principle.  Though the 40 Principles in TRIZ were established in the era of 1960s when the computers and software were not yet developed well, they have been found to very well explain or support the ideas of many inventive cases in the field of IT and software.  Mishra's book is a wonderful demonstration of turning a huge complex accumulation of technical knowledge into a treasury of essence of ideas.

-- TRIZ Forum: From Readers : Discussions on "TRIZ and Lean (and others)" (Toru Nakagawa (OGU), Yoichi Hasegawa, Osamu Kumasaka, Toshihiro Hayashi, Masao Ishihama (Kanagawa Inst. of Tech.), Tomomi Murata (Kita-Kyushu City Univ.), Naohiko Takayama (Shimadzu)) (Jul. 13, 2014)
Inspired by the paper "Lean-TRIZ instead of TRIZ-Lean" by C.M. Thurnes et al (Germany), we in Japan recently have some active discussions among the readers of this site.  In the Japanese page, email discussions among the seven persons are posted, while in the English page Nakagawa's messages and Takayama's Mind Map are shown.
On reading the paper, Nakagawa has found a lot for us to learn, think, and act, and wrote Editor's Note (PS) in the Japanese page, which is now translated into English.  Hasegawa responded to it intensively especially with a survey of the historical relationships in the development of Ford mass production system => Toyota production system (or Lean engineering) => TOC (Theory of Constraints).  Hayashi discusses the differences in the purposes of Toyota production system and TRIZ problem solving methodology and argues not to discuss them like alternatives.  Takayama shows the complementary relationships between TRIZ and Six sigma and suggests to clarify such relationships between TRIZ and Lean.  Nakagawa briefly reported about an open lecture by Toyota CEO Chairman Mr. Takeshi Uchiyamada on "Development of PRIUS".  He was the chief engineer of the PRIUS development project.  The ways of developing PRIUS were utterly different from the ordinary Toyota ways of developing new cars, and almost entirely opposite of Lean engineering, he says.   

-- Announcement: Publication Announcement of the Japanese Edition: Larry Ball's "Hierarchical TRIZ Algorithms -- Illustrated Course Material from Novices to Experts" (T. Nakagawa (CrePS Institute)) (Jun. 30, 2014)
Authored by Larry Ball, Japanese translation by Toshio Takahara and Toru Nakagawa, Published by the CrePS Institute, on Jun. 30, 2014.  Printed Edition: Soft cover, B5 size, 208 pages, full color, 4200 yen + tax, Print-on-Demand at DLmarket site.  Downloading Edition: PDF, A4 size, 208 pages, 2400 yen + tax, Digital downloading at DLmarket site.
The main body is the 160-page course materials posted in the "TRIZ Home Page in Japan" in 2006-2007 in Japanese translation .  In front of it, the book contains the introduction and the slides with annotation of the Keynote Lecture presented at Japan TRIZ Symposium 2007, as well as the new Preface by the author .  For making the most of so many illustrations, all pages are printed in color.
This is an excellent textbook of modernized TRIZ.  The author advocates that the decisions in the product development process should follow the logical pre-post relationships. The principal stages should be: Business and market needs => What system does => Identify pivotal functions => Idealize functional components => Idealize attributes of functional components.  These stages form the hierarchy of decisions, and hence a consistent flow of procedures.  During the processes of idealizing the functions and attributes, there appear various problems and contradictions, for which TRIZ tools can be used effectively.  Especially, the author demonstrates a large number of viewpoints of separation of Physical Contradictions, beyond classical TRIZ tools.  There are full of illustrations of small cases for explaining the concepts/processes.  The textbook is easy to understand and enjoyable for beginners, and yet is challenging for experts. 
For purchasing, please refer to the publication announcement page of the Series and access to the product page of CrePS Institute in the internet DLmarket site.  See the Flyer:

-- TRIZ Introduction Paper:  "Hierarchical TRIZ Algorithms" and Its Further Development (Larry Ball (USA), Japanese translation: T. Nakagawa)  (Jun. 30, 2014)
Preface for the Japanese Edition of Larry Ball's "Hierarchical TRIZ Algorithms", published by the CrePS Institute.
A 7-page Preface newly written down by the author for the Japanese Edition.  "Hierarchical TRIZ Algorithms" was originally posted in the TRIZ Journal in 2005-2006 and was presented in his Keynote Lecture at Japan TRIZ Symposium 2007.  The present article describes its essence reflecting his further development.  He has decomposed all the TRIZ tools together with various other methods related to product development and market development, and has reorganized them into an integrated process.  The guideline for the reconstruction is to clarify the input/output information of processes and to follow the logical pre/post relationships among the processes; he calls it a hierarchy of decision and finds a hierarchical algorithms for product development.  There are cases when an engineer comes up with an idea of a product, draws a prototype design, and requests for the funding.  Such cases fail very often, as statistics show, because he has started the project at a down stream after arbitrarily assuming the information to be decided at upper streams, the author says. The Hierarchical TRIZ Algorithms advises the transfer from 'selling what we can make' to 'making what we can sell'.
