  News:   TRIZCON2016 to be held on Mar. 3-5, 2016 at New Orleans, LA  (Jan. 9, 2016)

Altshuller Institute (USA) is making much efforts for rebuilding its activities, especially TRIZCON.  The host is Tulane University.  Call for Participation and detailed advance Agenda of the 3-day conference  are announced in their Web site.  Many keynote lectures, many tutorials, and many presentations are scheduled.  Nakagawa will give a presentation: "CrePS (General Methodology of Creative Problem Solving) beyond TRIZ: What, Why, and How?".

 From the Editor:  Message for the New Year 2016 (Toru Nakagawa)  (Jan. 9, 2016)

Greetings from Japan for a Happy New Year 2016!!  Wish the year be healthy, happy, and successful for you all and peaceful in the World.

Posted is my New Year Card (in Japanese and in English translation) which I sent to about 200 friends in Japan whom I met before my TRIZ days.  So it is just a yearly report of my activities.

 

  Forum:   Visual Thinking with 'Fuda-Yose' (12) -- Thinking over the poverty in the Japanese Society: [A] Increasing poverty among the elderly (7) Proposals of policy (Toru Nakagawa) (Jan. 9, 2016) 

Source reference: "Karyuu Roujin" ("The low-living elderly") by Takanori Fujita (Jun. 2015). Chapter 7:  For avoiding the decay of peaceful elder lives for all the 100 millions in Japan

In the last chapter of the book, the Author writes his personal proposals of policy. In the Fuda-Yose diagram, I arranged the labels in a two-dimensional way: From left to right: recognition of the problem situations and of basic principles --> consideration and reasoning --> proposal. From top to bottom: along the stages and logics of the components of the proposal.   Detailed version of the diagram (3 pages) was made first, then it was concentrated into the abstract version (1 page) , and finally the proposals are stated in sentences. Please refer to the parent page and also the abstract version diagrams of the whole book .

The Author proposes as follows in this chapter:
(1) First of all, the government should realize that the poverty exists widely and growing further in the people and should address the issue of correcting the income disparity and take measures to fight against poverty.
(2) Under the principles of fundamental human rights, Fundamental Law of Fighting against Poverty should be enacted, and the measures for preventing people from getting poor and for saving people from the poverty should be made as the important strategy of Japan.
(3) The government and all the municipal governments should inform that the poor and needy people (including the low-living elderly) can be saved by the social welfare and should guide them to apply for the welfare.
(4) The current system of social welfare should be decomposed into their support categories, so that the supports can be received more smoothly. By supporting the people for some partial categories in the current welfare, the people can make their own living before entirely losing their properties.
(5) Support the people for their housing rent (partially). This releases the low-living people (including the elderly and the young) from the rather heavy burden of rent and builds a better condition for the young to have their home, thus becomes effective as the measures for increasing children.
(6) The current reduction measures of the national pension premium should be informed, so that the low-living young people apply for the reduction instead of no payment in silence.
(7) In place of the current national pension system, a new system should be built in order to guarantee all the people for their living in their elderly days at the minimum level of healthy and cultural living which is guaranteed in the Constitution.
(8) After all, it corresponds to the living support in the social welfare system. Then the current national pension system should rather be quitted and integrated as the living support in the new social welfare system, as described in (4).
(9) For building a society where people can live happily, all the people in Japan should consider and choose proper systems including the taxation system for redistributing the wealth, and should proceed for its realization.
-- I personally agree with these proposals by the Author, Mr. Takanori Fujita.

  Forum:   Visual Thinking with 'Fuda-Yose' (11) -- Thinking over the poverty in the Japanese Society: [A] Increasing poverty among the elderly (6) How to protect yourself -- Measures before and in a low-living elderly situation (Toru Nakagawa) (Jan. 9, 2016) 

Source reference: "Karyuu Roujin" ("The low-living elderly") by Takanori Fujita (Jun. 2015).  Chapter 6. How to protect yourself -- For having a peaceful elder life

In Chapter 6, the Author advises first to the low-living elderly what they should learn and what they should do. Firstly, he explains the current social welfare system, e.g., how to apply for the social welfare, what are the requirements for receiving the welfare, and items and amounts of the welfare.  He also explains how to receive the medical care free of charge or at low cost, and advises about the recognition and attitudes.
Secondly he advises how to prevent from falling into the situation of the low-living elderly. "Savings are important", he says first of course, but he adds that human relationships in the elderly days are more important than money. Some people can be helped smoothly but some others can not be, he says. People who come early for asking assistance and who are of positive thinking can be helped smoothly. Holding good and rich human relationships and occasions/places of mutual assistance is helpful.  His concluding remarks is impressive:  "There are many elderly people who live happily even in their poverty. They commonly have rich communications and connections with other people."

Toru Nakagawa (Osaka Gakuin Univ.), Dec. 17, 2015
Source reference: "Karyuu Roujin" ("The low-living elderly") by Takanori Fujita (Jun. 2015).  Chapter 5. Old-built system and non-responsive policy produced the low-living elderly -- Government depending on individuals

In Chapter 5, the author examines the present system and policy related to the social welfare. He discusses in the following 8 aspects: (1) Income, (2) Saving, (3) Medical care, (4) Elderly care insurance, (5) Housing, (6) Human relationships, (7) Welfare, (8) Working conditions, (x)  The 'free/cheap lodging houses

He remarks the conclusion of this chapter very clearly, saying:
(a) The low-living elderly are produced by the present social system, and not by the lack of ability or idleness of the individuals.   (b) The present social system and policy of 'excessive priority in business and discarding the social weak' should be corrected; otherwise the problems of the low-living elderly and the poverty in the Japanese society will not be solved.   (c)   Furthermore, we should correct our own recognition and feelings that have been tamed by alienation of humans and neglect of human rights.

  Forum:   Visual Thinking with 'Fuda-Yose' (9) -- Thinking over the poverty in the Japanese Society: [A] Increasing poverty among the elderly (4) Issues of recognition and understanding (Toru Nakagawa) (Nov. 27, 2015) 

Source reference: "Karyuu Roujin" ("The low-living elderly") by Takanori Fujita (Jun. 2015). Chapter 4. The day when your arguments of 'Make more efforts' and 'Selfresponsibility' will kill yourself
In Chapter 4, the Author raises a question: "Despite the present situation of increasing number of the low-living elderly, why no serious measures have been implemented so far in Japan?".  He finds that the principal factors are poor awareness and ill-understanding by the general public.  Such factors push the low-living elderly to the margins of society, and the government's attitude of "providing no support without explicit request in person" makes the situation worse.
The Author is actively working with an NPO to support the low-living people.  He has received encouraging messages but much more negative and opposing ones from various people.  So he is discussing here in response to such messages.  The Author discusses logically, but the text seems somewhat complicated in the structure because of the involvement of multiple stakeholders.  Visualizing the discussion in the present work has made myself understood this issue much more clearly.
Visualized diagrams (in Japanese) are posted here:  Abstract version: in HTML and in PDF ; Detailed version in PDF An English page  is posted newly to show the outline of this series ([A] Increasing poverty among the elderly) with brief introductions in English.

The Author points out that the main reasons why no serious measures have been taken for supporting the low-living elderly increasing in number recently are the unawareness and ill-understanding by the general public in Japan.
We Japanese generally have the sound moral of 'to live without depending on others' help'. As a result, when we see or hear about the people who become unable to live self-dependently, we often think   "Their efforts are insufficient.  They themselves are responsible for their failure.  They should not dare to depend on the public support without further efforts and persistence." Such thoughts evaluate poorly the low-living elderly and push them towards the margins of society. 
However, viewing the issue in the whole scale of our society, we realize that it is inevitable to have the poor people besides the rich in the competitive society of capitalism. In the history of the humankind, the world has found 'Basic human rights' as a fundamental moral.  Constitution of Japan guarantees the people the right to maintain the minimum standards of healthy and cultural living.  Therefore, it is not 'overreliance' but 'rights' for the poor and needy people get a support from the country.  Recognition, or rather change in thoughts, in this direction is necessary for us all, i.e., the general public, the poor and needy people themselves, and the public administration. 
Under the limited national financial situations, how can we support the poor and needy people, not only the elderly but of all other generations, and in various situations?  We have to think over the big and complex problem with all our efforts.     (The discussion continues to the next Chapter.)

  Papers: The Third Collection of Papers Written by Toshio Takahara (2013-2015): "Theory of Resolving Differences (3) Dialectic Logic and the Way of Life" (Toshio Takahara)  (Nov. 16, 2015) 

The Third Collection contains 9 papers published from 2013 to 2015.  See the First Collection (2003-2007, 14 papers) and the Second Collection (2008-2012, 13 papers) . 'Resolving Differences' is a term coined by Takahara. Recognizing the differences between the wanted/desirable states and the real situations and then solving the gaps are the fundamental motives of human activities, which may take various forms and stages such as setting targets, problem recognition, designing, problem solving, etc.
The papers discuss over the Theory of Resolving Differences, in its wider sense, ranging from the basic concepts, to detailed logic of the methodology, and to the application of concepts. Its core part is the methods of Resolving Differences based on the Radical Enumerative Thinking. By pursuing the thinking methodology, he extended the Dialectic Logic as wider and deeper ways of Resolving Differences. Since he understands that the motivative force of Resolving Differences comes from individual humans, he discusses about the sense of values, world views, attitudes, and ways of recognition, etc. in individual humans, and he regards the whole as the Way of Life of individual humans. In the unified framework of his theory, he discusses about the basic nature of technologies and institutions, detailed logic of the methods of Resolving Differences, and the Way of Life of individual humans, etc. Toshio Takahara has been developing a philosophy with surprisingly large scope.
Nine papers in the present Collection are listed with links to HTML pages and PDF files (mostly written in Japanese). Takahara writes an Annotated Bibliography in Japanese. 
The 3-part Research Notes (newly posted now in Japanese) are the highlights of the Third Collection.   "There are much more unknown things than known ones. It is important to write what are not known yet", he says.  Thus he dared to write the paper of 55 pages in the form of Research Notes. We can read and trace Takahara's ever-developing thoughts up to date.

  On the 17th Anniversary of  "TRIZ Home Page in Japan":  Toru Nakagawa (Nov. 11, 2015)

This Web site "TRIZ Home Page in Japan" celebrates its 17th 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 2012, I have been proposing to establish a General methodology for creative problem solving & task achieving (CrePS) by integrating various creativity methods including TRIZ/USIT .  With the intention of widening the scope and application areas of TRIZ/CrePS, I have started to address social problems (especially, to visualize the problem of poverty in the Japanese society).  The number of visits since November 2005 is (on Nov. 11) 225,296 (increasing by about 13,000 for the last 1 year) to the top page in Japanese and 39,243 (increasing by about 2,500) to that in English.  Four Entrance Pages have been installed for your easy access to articles.  Readers' contributions either in English or in Japanese are heartily welcome.

  Forum:   Visual Thinking with 'Fuda-Yose' (8) -- Thinking over the poverty in the Japanese Society: [A] Increasing poverty among the elderly (3) Anybody has the risk of falling down to the low-living (Toru Nakagawa (OGU))  (Oct. 18, 2015)  (Nov. 27, 2015)

In Chapter 3, the Author, Takanori Fujita, points out five typical patterns of an elderly person falling down to the low-living: (1) Because of high medical expenses due to diseases or accidents; (2) Because of being not accepted by care houses due to the shortage in their capacity. (3) Because of their children being dependent to the elderly due to low income (working-but-poor, with less than 2million yen/year) or social withdrawal. (4) Due to increasing number of divorce of middle-aged or elderly couples. (5) Having become demented but no near-by family support.
The Author writes that the current working generation have much higher risks of falling down to the low-living in their elderly years:  (snip.  See some more in the New Information page in English)
-- I agree with these Author's views. It can be dangerous that most Japanese people still have the mentality of 'all Japanese are of middle class'. We should think and work hard to solve the problem of increasing poverty in the Japanese society.

For promoting the up-to-date TRIZ Contradiction Matrix, Matrix 2010 developed by Darrell Mann, we are happy to announce of a sales of his books together with the A2-size sheets of Matrix 2010 in their Japanese Editors.  The two sheets (of 3 pages) contain List of Parameters & List of Principles and the Matrix.  Thus, the modern Matrix 2010 are now purchasable inexpensively (additional price of 2500 yen for 5 sets of data sheets) for using in TRIZ application projects, company divisions, university seminar classes, etc. (Sorry but only for Japanese domestic delivery.)  Darrell Mann's message is posted.

     

 

  Forum:   Visual Thinking with 'Fuda-Yose' (7) -- Thinking over the poverty in the Japanese Society: (1) Increasing poverty among the elderly (2) Actual living of 'the low-living elderly': Cases and backgrounds (Toru Nakagawa)  (Sept. 30, 2015) (Nov. 27, 2015)
In Chapter 2 of Fujita's book, the Author describes 4 actual cases where ordinary people have 'unexpectedly' fallen into the status of 'the low-living elderly'.  Case (A) (Man of 76 years old, without marriage) Near the age of 40 while working regularly in a restaurant, his father was found ill of cancer.  So he quitted his job to go back to his parents' home and took care of his father for 1 year and then his mother for 10 more years.  Because no jobs were found in his home town, he moved to Tokyo area and worked in welfare facilities as an assistant-helper until 65.  He had the savings of 5 million yen at his retirement, and the pension of 90,000 yen/month.  The cost of apartment (50,000 yen) and treatment of low back pain and diabetes reduced the savings quickly.  With no savings any more, he had to fill his hunger with native grass.  [snip for cases (B)(C)(D)] -- Reading the description, I have drawn a graph of 'Personal history of Quality of life (especially stability)' sa shown in the right for Case (A).
The Author summarizes the background:  For the elderly, the income becomes much lower than before retirement.  Their desire of 'working some longer to get income for filling the shortage of pension' is often impracticable  The outgo, however, usually does not reduce as supposed, because of higher risks of 'unexpected' needs of much amount of money.  Many elderly people do not have enough savings.  Thus the poverty of the elderly is proceeding in Japan and a significant ratio of the elderly have already become at the low-living status.  Not only taking care of individual cases but also, more importantly, systematic social solutions to the widespread serious problems are necessary.

  Forum:   Visual Thinking with 'Fuda-Yose' (6) -- Thinking over the poverty in the Japanese Society: (1) Increasing poverty among the elderly (1) What is 'the low-living elderly' (Toru Nakagawa)  (Sept. 17, 2015) (Nov. 27, 2015)

I visualized Chapter 1 of Fujita's book with two Fuda-Yose diagrams, one showing 3 characteristics while the other 4 effects.
Characteristics: (1)  The income is remarkably low.  The national welfare minimum (composed of living and housing supports) is about 130,000 yen/month (or about 1.5 million yen/year) for a single elder person living in the metropolitan area.  The concept of 'Relative poverty' is used internationally; In the community (e.g.,a country or region), the persons whose income is lower than the half of the median of the income of the population.  This criterion gives 1.22 million yen for single persons, essentially equivalent to the national minimum welfare.  At this level of living, the basic needs of housing, food, medical care, etc. are often not fulfilled.  (2) Insufficient or no savings.  Low income requires to spend down one's savings, and insufficient savings will result in the crash in living due to any troubles.  (3)  No person to ask for a help (i.e., social isolation).  Due to the trend towards nuclear families, people often have no family members/relatives around. These characteristics mean the low-living elderly have lost all the safety nets and are in the situation where they can not live the healthy and cultural life which is ensured by the Constitution.  It is estimated that there exist about 6 to 7 millions of the low-living elderly at present in Japan. 
The second diagram illustrates 4 effects caused by the increase in the low-living elderly: (a) The elder and their child generations fall into poverty together.  (b) The culture of evaluating long happy life and elderly people will be lost.  (c) Decrease in the consumption by the young and middle-aged, thus resulting in stagnation of economy.  (d) Further reduction in the number of birth of children.

Source reference: "Karyuu Roujin - Ichi-oku sou rougo houkai-no shougeki" (The low-living elderly - Coming impacts by the decay of peaceful elder lives for all the 100 millions in Japan), by Takanori Fujita, Asahi Pocket Book 520, Asahi Shimbun Press, Jun. 30, 2015, pp. 222 (Note: The book title in English is Nakagawa's temporary translation)
I am trying in this page to understand the problem of poverty in the elderly by using the recently published book written by a young social worker, Mr. Takanori Fujita, and by visualizing the texts. I wrote down excerpts/abstracts of the original texts, made them into labels, and visualized the logic of the texts by using Katahira's Fuda-Yose tool in accordance with my understanding.  Thus the resultant diagrams are a sort of my rather-detailed notes of the book.  At the start of the series, I post the records of the intermediate stages of visualization for illustrating the process.
The author says:  "Today in Japan the low-living elderly are produced in a large number and we have a serious risk of facing with a situation where peaceful elder lives are lost for almost all the 100 millions of Japanese population.  In this book, 'Karyuu roujin' (or 'the low-living elderly') are defined as the elderly people living at/below the national minimum welfare level or facing with such a risk in living.  The real situations and their backgrounds are surprisingly unknown.  Describing the real problem situations in the full perspectives, we wish to think over solutions together with you, many readers."

  Forum:   Visual Thinking with 'Fuda-Yose' (4) -- Thinking over the poverty in the Japanese Society: Elderly, Middle aged, Young, and Child Generations (Toru Nakagawa)  (Sept. 17, 2015) (Nov. 27, 2015) 

I am going to start a series of pages on the theme, which is very big, complex, and important, as shown above, and wish to contribute to the society even little by little.   My intentions are:
(1) TRIZ/USIT is an approach of focusing and analyzing problems mostly in technical fields, but CrePS is demanded by the society to be applicable to big and complex problems in wider, different fields. So we should try to extend the usage of our methodology.
(2) For handling big and complex problems, we should better visualize the problems from full perspectives. The Fuda-Yose tool is expected to be useful for this purpose.
(3) Among a large variety of problems in the Real World, I chose this social problem because of its importance.
(4) The increasing poverty in the elderly generation, coupled with the low income for the young, tight living for the middle aged, and poverty effected on children, is going to give serious effects on the Japanese society in future.
(5) The politics in Japan is in a miserable state. Especially, Shinzo Abe's government is full of untruth and proceeds against the majority of Japanese people. We ourselves need to think over various problems logically and to speak out and act for making the future of Japan much better.
Having these intentions in mind, I am going to select some good references for visualizing the problems and wish to build up a methodology applicable to solving such complex problems.

  Forum:   Visual Thinking with 'Fuda-Yose' (3) - Visualizing the logic of Sickafus' Paper 'Subconscious Problem Solving Using Hazy Heuristics', (Akihiro Katahira, Toru Nakagawa)  (Aug. 25; Sept. 17, 2015)  (Sept. 17, 2015)

(A) Katahira has demonstrated to visualize the logic of Ed Sickafus' recent paper (in the Japanese version) with his Fuda-Yose (or Visual Thinking) method.  All the sentences of the paper are made into labels (or Fuda) and their logical relationships are shown in 'Fuda-Yose' diagrams section by section.  The diagrams are shown in PDF for the whole paper, and in HTML especially for the Abstract. 
(B) Nakagawa, reviewing them, thought that for clarifying the logic of a compact document like the Abstract we should decompose some sentences further into their logical units.  So I applied the Fuda-Yose method to the Abstract.  The visualization was actually done in 4 steps; the diagrams are posted in HTML, in PDF, and in the original Excel file.  This example has demonstrated the merit and easiness of Visual Thinking. 
(C) Using the original English texts, the Fuda-Yose diagrams were made in parallel to (B). Then the final diagram was further revised for clarifying the logic by suppressing some details.  The diagrams, including those in the intermediate steps, are posted in HTML , PDF , and Excel .  (Sept. 17, 2015)

  USIT Paper Q&A:   Q&A on USIT and the OAF diagram (in relation to "Subconscious Problem Solving Using Hazy Heuristics" by Ed Sickafus) (Q: Toru Nakagawa, A: Ed. Sickafus (Aug. 25; Sept. 17, 2015) 

This page records the fifteen email communications carried out last July in relation to Ed Sickafus' paper .  In particular, on my request, Dr. Sickafus kindly wrote a 4-page introductory article on the OAF diagram in USIT: 
    "Unification of USIT to One Graphic (OAF) Heuristics", Ed Sickafus, Jul. 2, 2015   PDF
He explains the definition and usage of the OAF diagram concisely and describes his research motivation towards fundamental principles in problem solving thinking. 
BTW, the start of SIT (Structured Inventive Thinking, later renamed as USIT) in Ford was revealed to be 1985 instead of 1995; the year shown in his USIT Textbook (1997) and in his USIT paper (1999) was found to be a typo.  USIT actually started earlier by 10 yeras.  

Further discussions, by Ed Sickafus, Toru Nakagawa, and Shahid Saleem Arshad, Aug. 14 to Sept. 15, 2015.   15 more email communications are added. (Sept. 17, 2015)

  USIT/CrePS paper:   Subconscious Problem Solving Using Hazy Heuristics (Ed Sickafus (Ntelleck, USA) (Aug. 25, 2015) ; Japanese translation: Toshio Takahara, Hideaki Kosha, Toru Nakagawa)  (Jul. 29, 2015);

This is a Keynote lecture given by Dr. Ed Sickafus (the original developer of USIT) at ICSI 2014, on Jul. 16-18, 2014.  He has shifted his focus to the research of the activities of our brains to get creative solutions and utilizing them effectively. In 2006 he discussed about the relationships between the logical thinking in the left brain and the image handling in the right brain and how to use them in collaboration.  In the present paper (2014), his study has extended further: "The 'Ah-ha!' ideas always come out of the subconscious. Invention is not done by the conscious, but done by the subconscious", Sickafus says. Thus he recognizes the importance of handing on the information appropriately to the subconscious.  He recommends to consider at the conscious level in the purposely-vague (or generalized) terms and images so as to enrich the subconscious ideation.  The author called the method "Hazy Heuristics". 
We have been developing the problem solving methods in the direction of making them structured and logical, i.e. 'Structured Problem Solving' methods.  Its purpose is to communicate about the methods among people and to build and educate the culture.   Once we have mastered such a method thoroughly, we as an individual may (and should better) use subconscious thinking more actively as the shortcuts in the problem solving process, he recommends. -- This may be the position of super-experts, as in the old saying "Enter the Form, and Leave the Form".

  Forum: From Readers:   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 usig 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) clearly shows the intentions of Nakagawa's request and corresponding answers by Katahira.

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 commited 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.

  CrePS/TRIZ/USIT Documents:   A Collection of USIT Case Studies: USIT: A Concise Process of Creative Problem Solving in the 'Six-Box Scheme' (Toru Nakagawa (OGU))   (May 25, 2015) (Jun. 26, 2015)

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 this Index page, the case studies are listed in a table.  Each case study is shown individually in an HTML page containing four 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. 

   USIT Case Study 1. How to fix a string shorter than the needle (Toru Nakagawa (OGU)), (May 25, 2015) (Jun. 26, 2015)

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.

 

    USIT Case Study 2. How to prevent a staple from being crashed (Toru Nakagawa (OGU)), (May 25, 2015) (Jun. 26, 2015)

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.  Initailly 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.  

 

   USIT Case Study 3. Saving Water for a Toilet System (Toru Nakagawa (OGU)), (May 25, 2015) (Jun. 26, 2015)

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

 

   USIT Case Study 4. Picture Hanging Kit Problem (Toru Nakagawa (OGU))(May 25, 2015) (Jun. 26, 2015)

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.

 

   USIT Case Study 5. Increase the Foam Ratio of Porous Polymer Sheet (Toru Nakagawa (OGU)) (May 25, 2015) (Jun. 26, 2015)

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 is solved with the Particles Method.

 

  CrePS/TRIZ/USIT Documents:   USIT Manual: USIT: A Concise Process of Creative Problem Solving in the 'Six-Box Scheme' (Toru Nakagawa (OGU))  (May 25, 2015) (Jun. 26, 2015)

USIT ('Unified Structured Inventive Thinking') was originally developed by Dr. Ed Sickafus (1995) as a concise and consistent problem solving process and 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), which can include/unify TRIZ, USIT, and many other creative problem solving methods. 
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.  Examples of USIT usage in the 'Collection of USIT Case Studies' are described along the steps of the 'USIT Manual so that you can understand USIT fully in its variety of usage.  The Manual is posted both in HTML (with images) and in PDF .

 TRIZ News:  The TRIZ Journal has been restarted on Jun. 11, 2015 by BMGI.    (Jun. 19, 2015)

  TRIZ Paper: Fundamental Theory:  A Note on a Method and Granularity in the Structure of the World (Toshio Takahara)  (Apr. 12, 2015)

An 8-page paper presented at FIT2013 on Sept. 4, 2013.  Mr. Takahara's life-work theme is "To understand the world in a consistent manner, to realize the real basis of our human ways of living, and to establish a general and logical methodology for such a study."  As the basis of his logic, he builds the concepts of 'existing things' and their relationships, and also the ways of describing the whole world, which contains technologies, institutions, and persons.  For such a description, he finds the necessity of 'radical enumerative thinking' (i.e., a clearer extension of 'systematic thinking') and expressions of contradictions (i.e., a clear extension of 'problems'). He also extends the logics of dialectics in a much wider meaning.  Then he considers the basis of person's recognitions and actions and derives how the person decides them, with a range of consideration (i.e. granularity) and with a logic for solution (i.e., a thinking method). He discusses further basis of the person, i.e., the person's attitudes.  The width and depth, and clarity, of the author's consideration is indeed astonishing.

 TRIZ/USIT/CrePS Talk:  Methodology of Creative Problem Solving: TRIZ and Its Extension ~ Scientific Methods for Innovation ~ (Toru Nakagawa)  (Apr. 12, 2015)

The 57 slides were given in a lecture for 90 minutes at Graduate School of Medical Science, Tottori University, on Jan. 20, 2015.   I first describe that the basic Four-Box Scheme of Abstraction which is generally assumed in the current science and technology has a limitation and that many conventional 'Creativity methods' address with different partial aspects without having a sound overall view.  As new scientific approaches to inventive thinking, I explain TRIZ first and then USIT.  On the basis of them, the Six-Box Scheme was newly formulated as the paradigm for 'General Methodology of Creative Problem Solving' (CrePS).  These four stages of development of the methodology of creative problem solving reflect my own understanding for these 18 years.  Slides in Japanese  and also in English translation  .
