Keynote Lecture:  EI01- Cavallucci (France)

How TRIZ can contribute to a paradigm change in R&D practices?
Denis Cavallucci (INSA Strasbourg, France)

Tools and methods developed during the era of quality and optimization have shown their limitations and become inappropriate in the context of the requirements of innovation. Nowadays the need to rebuild design practices in enterprises is strongly felt both in terms of human skills and methodological expertise. In part, a way to face the innovation era’s difficulties has been provided through the theory of inventive problem solving. But as TRIZ becomes more popular both in academia and industry, difficulties to obtain the best out of it is strongly felt whether we use its simplified versions or its computerized one. This keynote addresses this difficulty in presenting an original and complete framework, using industrial examples, that integrate most of TRIZ fundamentals in a methodology namely Inventive Design Method (IDM).

Special Invited Lecture:  JI04- Yumino (Japan Creativity Society)

Educating Creativity: Making the foundation for disseminating creation techniques
Kenichi YUMINO
(President of Japan Creativity Society; Emeritus Professor of Shizuoka University)

The question of “What”, “Why” and “How” are closely related to the emergence and progress of the study, science and technology. For these questions, Japanese schools and society that put value on “Manabi: Learning” give priority to the "How" question. However, there is “Tsukuri: Creation” together with Manabi, in the education of the "West European countries" which has firstly initiated the study, science and technology. Tsukuri includes something original for the person, not others' imitation, and involves what and why question.

When we think Tsukuri as making the foundation for disseminating creation techniques, it will be necessary to set up the special "view points" which are not included in the traditional culture or education in Japan. These are: a)not only conjecturing the opinion of a author but also requiring a learner's logic and opinion, b)praising a challenge, c) praising creative behaviors, d)praising "originality” and "uniqueness", e) evaluating not only correct answer but also the process of thinking, and f)encouraging debate and discussion based on data and the fact, etc.

If a child grows up with a custom to consider an ambiguous problem by praising from above view points, and mastered creation techniques, such as TRIZ, it might be expected that the higher quality of ideas will be obtained. In this small lecture, I'd like to introduce examples about "Manabi" and "Tsukuri", "Intelligence" and "Creativity", "Western education" and "Japan's education", "the way of praising that develops Intelligence and Creativity", and add comments about these.

Special Invited Talk:  EI03- Shin (Korea)

How to learn TRIZ with ease and fun
Jeongho Shin (eTRIZ, Korea)

As TRIZ is undoubtedly one of the most popular methodologies for systematic problem solving, it is now widely used to improve products, services, and systems. However, most of the people who learn TRIZ for the first time think that TRIZ is very difficult and assume that it takes much time to go to the level of applying TRIZ. In order to invite them to the TRIZ world, there should be a measure to help them. This paper introduces three approaches that help learn TRIZ with ease and fun. Firstly, the SCM (Simple Contradiction Modeling) has been developed for easy modeling of contradictions using a diagram that consists of 5 components. A user can easily describe contradictions and explain to others with the help of the visual diagram. Secondly, the Invention Song helps memorize invention principles. Each line of the song stands for one of 8 invention principles selected from 40. Lastly, the Invention Card can be used for playing as well as brainstorming. Using this card, a user can easily check all the invention principles and those typical examples and apply to generate ideas like playing. It is illustrated that easy and funny approaches can be utilized as good instruments for training TRIZ beginners.

  Seminar (A) in Japanese on the First Day (Sept. 6, 2012 (Thu.)): Abstracts by the Authors

Tutorial: JI05-Kasai (IDEA)

Basics and Usage of TRIZ
Hajime Kasai (IDEA Co.)



Special Interest Lecture (a):  JI06-Kurosawa

“Physical Contradiction” - A study
KUROSAWA, Shinsuke

“Physical Contradiction” is one of the key concepts of TRIZ, the problem solving method. It is a good idea to review this important concept together with the audience of the Japan TRIZ Symposium. Following issues are planned to be discussed:
Placing of the Physical Contradiction in the system of Theory of Inventive Problem Solving
      How was the concept born?
      How is the concept treated in the contemporary world TRIZ community?
      How to use Physical Contradiction as a TRIZ tool

Special Interest Lecture (b):  JI07-Kikuchi

Introduction of cases using TRIZ in corporations
Fumiko Kikuchi (Pioneer Corporation), Coordinator: Setsuo Arita (Hitachi, Ltd.)

On the whole, staffs in a corporation who are employing TRIZ (regardless of the way of applying) for solving problems belong to R&D section, developing/designing section or HRD (Human Resource Development) section. On the contrary, a person who would like to introduce TRIZ into his (her) company points out the existence of obstacles even though he (she) considers that TRIZ is powerful and useful. This presentation has some actual cases which were already released in past symposiums and some consideration from some points of view. It is helpful for people who would like to introduce TRIZ into their companies or would like to know TRIZ more.

Special Interest Lecture (c1):  JI08-Nakagawa

How Can We Proliferate TRIZ among Younger People? -- Education and Training Experiences of Problem Solving with TRIZ
Coordinator: Toru Nakagawa (Osaka Gakuin University)

We, Japan TRIZ Society, recognize the importance of proliferating TRIZ to younger people much better and wider. There can be several different approaches: (a) to challenge the atmosphere of the current era for younger people, (b) to present TRIZ in the form acceptable to the background of the younger people, (c) to make TRIZ easier to understand/accept, (d) to let them practice rather than to let them learn the knowledge, (e) to expand the applicable areas of TRIZ, etc. In the present Symposium, various authors are presenting and discussing their own works in these different approaches. In the present session of Special Interest Talks, we are going to have a few short presentations of case studies of TRIZ education/training at universities, graduate schools, and industries (especially for fresh employees). We would like to put stress on the approaches with exercises and practices of real problem solving rather than those of teaching/lecturing the knowledge of TRIZ methods.

Special Interest Lecture (c2):  JI09-Ikeda

Report of Lecture Series on Invention at a Graduate School: Aimed for Revival of Japan as a Nation of Outstanding Technology
Akihiko Ikeda (Kanagawa Institute of Technology and Sony) and Masao Ishihama (Kanagawa Institute of Technology)

How can we improve our inventive mind and skill? When is the best time to start learning invention? The author has been continuously asking these questions to himself since he came across TRIZ for the first time. If we can answer to these questions, then revival of Japan as a nation of outstanding technological power will follow. Further, contribution to the world wide social development will be made by solving problems across country borders through invention. As the first step to answer to the questions above, a lecture series titled “Creative Problem Solving” was conducted at a graduate school of Kanagawa Institute of Technology in the year of 2010.

How can we educate students who don’t have any work experience in industry? To meet this challenge, an in-company training program that the author had created was implemented with some modification. In this modification, the author exploited his own experiences of consulting research and development in industry. The author’s first and most important idea for effective teaching was to let the students enjoy invention. This naturally led the students realizing the importance of creativity. In this report, such items as activities to encourage students move from learning theory to applying it, the students’ impression on this lectures and the teacher’s impression are described.

  Seminar (B) in English on the First Day (Sept. 6, 2012 (Thu.)): Abstract by the Author

Advanced Seminar: EI02- Cavallucci (France)

From TRIZ to Inventive Design Method (IDM): towards a formalization of Inventive Practices in R&D Departments
Denis Cavallucci (INSA Strasbourg, France)

In today’s methodological world, TRIZ has undoubtedly its place in the myriad of methods and tools useful for engineers in companies. Mostly dedicated for solving inventive problems, TRIZ is appreciated for its capacity to widen the scope of possible domains in which the solution is sought after. In that regards, it is often perceived by companies as a potential replacer of creativity techniques such as Brainstorming. We disagree with this statement in presenting TRIZ as, firstly, a theoretical framework for inventive thinking, second, as any theory, it aims to serve as a framework for developing new methods and tools useful in a certain context. Inventive Design Method (IDM) has been developed to re-structure and complete TRIZ body of knowledge with other theories like graph theory or Pugh’s theory. The objective is to integrate companies’ set of methods to pragmatically serve an innovation strategy with engineering tools open to invention. This advanced seminar is provided to describe, with concrete exercises, the main stages of IDM.

Extended Abstract

Our industry is currently undergoing a transformation that is guiding it from the quality era to that of innovation. This transformation necessarily involves changing design practices, the foundations of which currently rest on an optimization mentality. An innovation oriented approach would require that the bases of the design action contain other rules of invention where creativity and problem solving would have priority.

The methodology we discuss in this advanced tutorial (namely Inventive Design Method) is the result of 10 years of research at INSA Strasbourg (from [1] to [8]). It concerns the mapping of known information and the transformation of these pieces of information into a model that will facilitate a later problem solving stage.

IDM framework proposes four main phases to evolve from a fuzzy and multidisciplinary initial situation to a set of ranked inventive solution concepts. Here is a short description of theses phases:

Phase 1: Initial Situation Analysis: As stated in the introduction, this phase aims at investigating all the knowledge related to the study. This knowledge (tacit or explicit, coming from text documents of from experts’ minds) is translated into a graphical model, mathematically exploitable, to facilitate decision-making.

Phase 2: Problems Mapping: Once the complete initial situation has been stated, a reduced set of problems must then be detailed by a set of contradictions. These contradictions represent bottlenecks in the evolution of the studied system. In this phase, we find sub-steps such as, poly-contradictions formulation, contradictions extraction and classification of the importance of contradictions in accordance with a specific scenario.

Phase 3: Solutions Concepts Synthesis: Each contradiction declared as a priority for the solving phase becomes an input point for the use of the different TRIZ techniques and tools. Each contradiction must be engaged in a solving process to be resolved without compromises. At the end of multiple solving stages, which can be successive or iterative, we can include the use of Altshuller’s matrix associated with inventive principles, Substance-Field modelling associated with the system of Inventive Standards or even ARIZ-85C. Expectations regarding this phase are the generation of a limited number of solution concepts and the possibility of tracking their origin for the follow-up of the study.

Phase 4: Feedback between Solution Concepts and the Initial Situation: in this phase, we measure the impact of each solution concept with the problem graph elaborated in phase 1. This stage is built to estimate the hypothetical impact of each Solution Concept and choose that will be the subject of future developments.

A macro-representation of this process so as the information flow along the four phases is given figure 1.

Coordinators:  Mamoru Zenko, Shusei Kunitomo, Takeshi Ogata.
Free discussion in Japanese on the topic.

Group 3: "How to Proliferate and Teach TRIZ to Younger People",
(first 60 minutes in English during, and later 30 minutes in two separape groups one in English the other in Japanese.)
Coordinators: Toru Nakagawa, Maso Ishihama, Akihioko Ikeda; (Prof. SeungHyun Yoo)
"What should we do to convey TRIZ (or more widely the 'Creative thinking for problem solving') to younger people (such as businessmen/engineers of up to 2-3 years of experiences, university students, high- and middle school people, and children). This theme is one of the main pillars of topics in the present Symposium.
First we wouldlike to learn Dr. Shin' approach and try to sing the Invention Song together as a rehearsal.  Some relevant presentations from overseas (e.g. Prof. Yoo) and from Japan will be introduced briefly, to clirify ther intentions.  During the last 30 minutes, free discussions are expected."
