Dear TRIZ Colleagues,

"TRIZ Home Page in Japan" has been renewed !!!

   in the Japanese pages in September and

   in the English pages today in October.


Tonight, three Japanese researchers, Prof. Isamu Akasaki,    Prof. Hiroshi Amano, and Prof. Shuji Nakamura are

   jointly awarded the Nobel Prize in Physics 2014 for the invention of blue LEDs. Congratulations!!

   Here I am posting a paper which investigates the Blue LED Innovation in the depth of science and also technology management:  

[1] Rethinking Innovation

   (The Blue LED case and Paradigm Disruptive Innovation) by Eiichi Yamaguchi (Doshisha Univ.) (2006)


[1] Innovation Paper:

   Rethinking Innovation - (The Blue LED case and Paradigm Disruptive Innovation) Eiichi Yamaguchi (Doshisha Univ.; currently: Kyoto Univ.)

   in "Recovering from Success: Innovation And Technology Management in Japan", edited by R. Cole and D. Hugh Whittaker, Oxford University Press (May 2006).

   In the Japanese page:

   Structure of Innovation - What is Paradigm-Disruptive Innovation? (Analysis of the Blue LED Innovation), by Eiichi Yamaguchi, Doshisha Univ. ITEC Research Paper

   Series, Vol.4 No.13, pp.1 - 15 2004 Professor Eiichi 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".


   -- 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.

[2] TRIZ Forum: Conference Report (30) Personal Report of The 10th TRIZ Symposium in Japan, 2014 Sept. 11-12, 2014, Tokyo) 

   Toru Nakagawa (Osaka Gakuinn University), Nov. 24, 2014.

   The 10th Japan TRIZ Symposium 2014 was held last September by Japan TRIZ Society.

   Being late to my regret, I am writing here my Personal Report for introducing you the event and all the presentations briefly.

   I think it important for us Japanese TRIZ community to inform you, TRIZ people in the world, about the activities and advancements of TRIZ in Japan.


   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. (The Program Committee supported the translation of most

   presentations into English by using machine translation software. However, the English versions need to be brushhed up further.)  

   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 successfully 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 given by a national college of technology (i.e., a school for year 15-20-22 students), 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. I am planning to post several selected presentations of the Symposium publicly in this Web site under the

   permissions by the authors.

What Makes Samsung Such An Innovative Company?

By Haydn Shaughnessy, Contributor,

“I write about enterprise innovation”

Tech 3/07/2013 @ 6:32AM |50,392 views Forbes Magazine

Full article at:

Samsung is a global leader in screen technology, TVs, batteries, and chip design. So in terms of innovation it is doing a lot right. But we know very little about how.

Two developments convinced the company in the late 1990s and early 2000s that they could adopt a systematic approach to innovation and that is what seems to underpin their current success.

The first development provides a broader explanation for Samsung’s innovation capacity. In the late 1990s they were able to tap into a source of cheap scientific expertise in the former Soviet Union.

In 2009 BusinessWeek reported that Samsung relied on its relationships with Russian experts for its smartphone software development, adding: “Russian brains helped Samsung develop the image-processing chips in its digital TVs and refine its frequency-filtering technology that significantly reduced noise on its now-ubiquitous handsets.”

But a second effect of the relationship with Russian science was the introduction of TRIZ, an innovation method that Samsung adopted from 2000 onwards but which only reached American companies from the mid-2000s onwards (Intel is a user).

TRIZ is a methodology for systematic problem solving. Typical of its origins in Russia, it asks users to seek the contradictions in current technological conditions and customer needs and to imagine an ideal state that innovation should drive towards.

Samsung had early successes with TRIZ, saving over $100 million in its first few projects. It was also adopting Six Sigma at the time.

But it was TRIZ that became the bedrock of innovation at Samsung. And it was introduced at Samsung by Russian engineers whom Samsung had hired into its Seoul Labs in the early 2000s.

In 2003 TRIZ led to 50 new patents for Samsung and in 2004 one project alone, a DVD pick-up innovation, saved Samsung over $100 million. TRIZ is now an obligatory skill set if you want to advance within Samsung.

At the Samsung Advanced Institute for Technology, Hyo June Kim, who wrote The Theory of Inventive Problem Solving, a foundation text on TRIZ published in Korean, trained over 1,000 engineers across Samsung companies in 2004 alone.                  

What we know from this is how Samsung approaches innovation. Rather it is based on developing a creative elite. This explains how Samsung used TRIZ to get to its Super AMOLED displays.

Samsung Electronics has a sense of crisis that we have been a fast follower and we can not survive anymore in this position. Instead of leading the industry by developing innovative products, we have followed fast what the leading companies had developed. Top management pointed out this and asked employee not to be a fast follower, but to be an innovative leader.

At Samsung even the subsidiary CEO has to take TRIZ training. From looking at the various presentations I estimate that engineers get about 15 days of training plus 7 days specific project work. That’s quite an investment in method and people.

So the answer to why Samsung is so innovative – with at least two major product announcements this month – is that it is heavily invested in its people, it goes in search of special talent wherever it can find it, but specifically made astute moves into Russia early on; it targets its innovations towards specific competitors and patents that it wants to overhaul (as Apple did under Jobs); and it has an innovation culture based on extensive training, repeatable methodology and creative elite formation, backed by the highest levels of management.
