   Visual Thinking with 'Fuda-Yose' (1) - Example of Burning Suicide in Shinkansen Case

   Akihiro Katahira, Toru Nakagawa

   Jul. 7, 2015; Jul. 8; Jul. 19, 2015 -- No English page

   Visual Thinking method and its tool 'Fuda-Yose' were developed by Akihoro Katahira and introduced in this site on Jan. 18, 2015.

   For showing its usefulness, I asked him to show examples of usage on various themes.

   The shocking case that a 71 yrs-old man committed suicide by burning himself on a Shinkansen train on Jun. 30, 2015

   was used as an example.

   The old man's mental and social situations are described with the hope of reflecting the problems in the society in Japan.

[2] Visual Thinking with 'Fuda-Yose' (2) - Converting a (short) document into labels and make 'Fuda-Yose' diagrams for Visual Thinking

   Toru Nakagawa, Akihiro Katahira  Jul. 29, 2015       -- No English page yet.

   As a basis of using Visual Thinking, Nakagawa asked Katahira to show the method of converting a (short)

   document into labels automatically and making 'Fuda-Yose' diagrams.

   Katahira demonstrated the method by using Nakagawa's request message.

   He has made a detailed record of the conversion and drawing, in the 'Fuda-Yose' Excel sheets.

   The final 'Fuda-Yose' diagram (click the figure at right on the top page) clearly shows the intentions

   of Nakagawa's request and corresponding answers by Katahira.

   Dr. Ed Sickafus (the original developer of USIT) gave this keynote lecture at ICSI 2014 (5th International

   Conference of Systematic Innovation) at San Jose, CA, on Jul. 16-18, 2014.

   We have translated it into Japanese and posted it in this site.

On Jun. 15-17, I paricipated at ICSI2015 held at Hong Kong, and gave a Tutorial and a Keynote on USIT and Six-Box Scheme.

The ICSI2015 was successful, and it was fruitful for me. I will post my presentations some time later.


Best wishes,

"TRIZ Home Page in Japan" has been updated tonight

   (dated Jun. 27. 2015) in the English and Japanese pages.

A full set of documents of USIT originally posted here in Japanese on May 25, 2015 is now posted in English.

   USIT: A Concise Process of Creative Problem Solving in the 'Six-Box Scheme'


   Toru Nakagawa (OGU), (in Japanese: May 25, 2015), (in English:   Jun. 26, 2015)

   USIT ('Unified Structured Inventive Thinking') was originally developed by Dr. Ed Sickafus (1995) as a concise and consistent problem solving process.

   It has been extended further in Japan by integrating and unifying various TRIZ methods into USIT. By recognizing the Six-Box Scheme (of USIT) as a new paradigm of creative problem solving, USIT is now established as a concise overall process for the real practice of the General Methodology of Creative Problem Solving (CrePS).

   CrePS can include/unify TRIZ, USIT, and many other creative problem solving methods.


[1] USIT Process Documents (Index page)

   This page has the indexes of the following 4 items:.

   (A) USIT Manual  

   (B) USIT Case Studies

   (C) USIT Operators

   (D) USIT References

[2] USIT Manual

   Manual of the USIT process has been described in the form of 31 slides along its steps.

   The USIT process is now fully described by use of the consistent demonstration of a case study and instructions

   and remarks on the USIT concepts and its thinking process.

   The Manual is posted both in HTML (with images) and in PDF.

[3] A Collection of USIT Case Studies:

   A number of case studies published so far in different places are collected here.

   Individual case studies are described in full extent in a consistent format according to the USIT Manual .  

   Pleae note that several case studies originally carried out with some other methods than USIT (e.g., TRIZ and

   others) are also described in the 'Six-Box Scheme' and are shown here as 'USIT case studies'.

   In the Index page, the case studies are listed in a table.

     -- Symbol figures of USIT Case Strudies are shown in the attached gif file.

   Each case study is shown individually in an HTML page containing 4 slides (3 introduction slides and 1 overview

   summary slide in the 'Six-Box Scheme') and in a PDF file of the whole set of slides.

(1) USIT Case Study 1.

       How to fix a string shorter than the needle

   This Case Study is originally based on Tsubasa Shimoda's Thesis at OGU (2006) and revised further by Nakagawa.

   For a familiar, everyday-life problem, the USIT thinking process from the problem definition to the solution

   construction is explained well.

   Even children can understand how to think for this problem.


(2) USIT Case Study 2.

       How to prevent a staple from being crashed

   This Case Study is originally based on Kazuaki Kamiya's Thesis at OGU (2004) and is further revised by Nakagawa.

   In binding sheets of papers with a stapler, the staple may be crashed in case of 30 or more sheets.

   We wanted to improve the stapler so as to be able to bind some more sheets.

   Initially we suspected that the looseness around the axle was the cause of weakness.

   In the middle of some experiment, we met an unexpected phenomenon and found the root cause of the problem.

   For solving the problem we used Altshuller's Smart Little People's Modeling (SLP).

   Even children can understand and enjoy this case study.


(3) USIT Case Study 3.

       Saving Water for a Toilet System

   Source Ref. Hong Suk Lee and Kyeong-Won Lee (Korea), The TRIZ Journal (Nov. 2003)

   This Case Study has solved a familiar, widely known problem 'how to save the water consumption for flushing in a toilet system'.

   The authors applied the concept of Physical Contradiction of TRIZ to this problem and solved it excellently.

   Once they show how to define the problem and how to handle it, even school children would start suggesting

   ideas just like the ones in this Case Study.

   By describing this Case Study in the 'Six-Box Scheme' of USIT, we can easily follow its thinking process.


(4) USIT Case Study 4.

       Picture Hanging Kit Problem

   This case was originally described by Dr. Ed Sickafus in his USIT Textbook (1995).

   It has been used, revised, and extended by Toru Nakagawa as a standard USIT case study along with the development of USIT itself.

   A standard USIT Case Study on a familiar problem, easy to understand for everybody and yet deep in thoughts.


(5) USIT Case Study 5.

       Increase the Foam Ratio of Porous Polymer Sheet

   This Case Study was originally made by Toru Nakagawa

   at the 3-day USIT Training Seminar conducted by Dr. Ed Sickafus in Mar. 1999.

   It used the Particles Method, an extension of Altshuller's Smart Little People's Modeling (SLP), effectively in solving the problem.

   In the description of the present Case Study, I inserted the Atttribute and Functional Analyses, which were

   skipped in the original case study, for the purpose to illustrate the USIT process fullly.

   A real problem in the field of chemical engineering was solved with the Particles Method.


[4] USIT Operators:     (in [1])

   The System of 'USIT Operators' were obtained in 2002 by reorganizing and unifying all the solution generation

   methods of TRIZ and USIT (by Toru Nakagawa, Hideaki Kosha, and Yuji Mihara).  

   Details of them and the relationships between USIT Operators and TRIZ methods in the dual directions were already posted in the present site.

   In the Index page [1], indexes of such postings are summarized for easier reference:

   Links to the pages of simple/full/extended versions of USIT Operators,

   Cross Indexes to USIT Operators => TRIZ tools and TRIZ tools => USIT Operators.


[5] USIT References:   (in [1])

   Theoretical/methodological USIT references are listed.

     (1 by Ed Sickafus, 21 by Toru Nakagawa, and 3 by Nakagawa, Kosha, and Mihara)

   References in the aspects of application may be referred in the Case Study articles.


I am going to give a Tutorial Lecture on USIT at ICSI2015

to be held at Hong Kong on Jul. 15-17, 2015.


Best wishes,

Toru Nakagawa

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.
