TRIZ Home Page in Japan-13 July

Updated: 13 July 2014


Dear TRIZ Colleagues,

From : Toru Nakagawa, Professor Emeritus, Osaka Gakuin University 


"TRIZ Home Page in Japan" has been updated on 30 April in English and in Japanese pages:


[1] From Readers: Discussions on "TRIZ and Lean (and others)"

   T. Nakagawa, Y. Hasegawa, O. Kumasaka, T. Hayashi, M. Ishihama, T. Murata, N. Takayama


[1] 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)


   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.

[2] TRIZ Introduction Paper:"Hierarchical TRIZ Algorithms" and Its Further Development Larry Ball (Honeywell, USA), Jun. 15, 2014

   (Japanese translation: Toru Nakagawa (OGU)), Preface for the Japanese Edition of Larry Ball's "Hierarchical TRIZ Algorithms"

   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




[3] Announcement:

   Publication Announcement of the Japanese Edition: Larry Ball's "Hierarchical TRIZ Algorithms -- Illustrated Course Material from Novices to Experts" Authored by Larry Ball, Japanese translation by Toshio Takahara and Toru Nakagawa,  Published by the CrePS Institute, Kashiwa, Chiba, Japan, 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.

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.
