Trend of TRIZ Application in Industries in the World

Isak Bukhman（President of Altshuller Institute for TRIZ Studies, USA)It is very difficult (maybe even not possible) to create a clear trend of TRIZ (TRIZ Technology for
Innovation) application in industries around the World. We do not have an exact number ofprojects where TRIZ was used. We do not have information about these projects' importanceand how good they were created in hundreds of big and small industrial companies in theWorld. We do not have access to these projects' details; it is very secure and secret informationin most cases.
I prepared my presentation based on my personal experience of working with many leading andfamous industrial companies. I also have used precious information received from many of mypartners and colleagues around the World.
In the presentation will be highlighted the following moments:
1. Which kinds of projects were successfully created by using TRIZ for different
companies around the World?
2. Strategy and tendency of using TRIZ in industrial companies.
3. Integration of TRIZ into different companies
4. Positive and negative lessons we learned on the way of using TRIZ in different
companies.
5. Recommendations for integration and using TRIZ for industrial companies.

Open innovation by academia-industry cooperation
Koichi Sumikura, Professor, National Graduate Institute for Policy
Studies
Private companies in R&D oriented industries are moving toward open innovation, not only depending on
knowledge inside but using outsider knowledge for creation of new products and services andintroduction of new processes. Universities are expected as a provider of knowledge for innovation andvarious forms of academia-industry cooperation are going on. In this presentation I argue how to
overcome misunderstanding or mismatch between academia and industry to implement innovation
sustainably by their cooperation.

Koichi Akagi（Mitsubishi Power, Ltd.）

Proposal of how to use TRIZ for work improvement
Verification with a large gas turbine
Koichi Akagi（Mitsubishi Power, Ltd.）、Manabu Sawaguchi（Ritsumeikan

University）
Improvements to conventional on-site work have been carried out by small groupteams that are mainly on-site, and IE and QC have been mainly used as methods tobe utilized. And this activity has definitely been successful. However, due to thedecrease in the number of field workers due to the declining birthrate in recent
years and the rapid progress of ICT, it is necessary to change the method of
improving field work. The authors are promoting the improvement of field work
according to the concept of the SECI model of organizational knowledge creation.
This converts field work information into explicit knowledge information to build a
database, and uses that information to implement organizational improvements.
Next, it is an activity to provide improved information to the site and share theinformation throughout the organization including the site. The authors devised a
procedure to combine FAST and TRIZ as one method to utilize this information to
implement organizational improvement. First, the problems of field work arevisualized by the FAST diagram. And as a method of continuous improvement,
TRIZ's "Technical Contradiction and Invention Principle" will be utilized. On the other
hand, TRIZ's "Trend of technological evolution" will be utilized as a method ofdestructive improvement. In this practical paper, we discuss this method and reporta practical example of using this method to create an improvement plan for theprocessing of parts of an actual large gas turbine.

Survey of application of solution tools to manufacturing
improvement ideas
Koichi Akagi（Mitsubishi Power, Ltd.）
Based on the results of the 10-year manufacturing VE that has been carried out by3

Mitsubishi Heavy Industries, we will extract specific examples of brainstorming ideas
from functions. As a concrete example, we investigate which of the TRIZ solution
tools was applied to come up with the same idea. Using the results of this survey,
we will be able to actively apply TRIZ solution tools as well as brainstorming.

Therefore, extending the life of infrastructure is an issue, andinnovative technologies for maintenance and repair are required. There is. This
paper focuses on the development of road structure maintenance and repair
technology, and designs an innovative and concrete ideal form by combining thedialectic aufheben process and TRIZ's physical contradiction resolution method (lawof separation). We propose an approach for this.

TRIZ's 9-screen method is powerful, but usage opportunities ≒ improvement
opportunities were limited. Therefore, we adopted labels such as "environment /element" and "user / invention element" on the vertical system axis. In addition, we
tried multiple usages with the horizontal axis as the "right column for ideas andhypotheses" such as "conventional → new → guessing". This makes it a thinking
support tool that can consistently "organize-> think-> transmit" information in awide range of daily life.

～All New Graduators Experience TRIZ with Fun and Interest～

Motoharu Miki (OLYMPUS Corporation)

Olympus has promoted “7 solutions” based on QFD, TRIZ, and Taguchi Method to meet theneeds of R&D engineers with focusing on upstream of the development process since 2012.
By our activities, R&D engineers have begun to recognize the above 3 Scientific Approaches.
However, only engineers in some departments were utilizing them and the situation did notreach the company-wide expansion that should be aimed at. Therefore, in order to broaden thebase of utilization of scientific approaches, we held a seminar (*) where the new graduators
could experience TRIZ as a part of company-wide group training for them in collaboration with
the Human Resources Education Department. As the result, we were able to promote theattendance of in-house training on the scientific approach and we were able to get a chance forthe company-wide expansion.

Development and results of business model idea idea
tool that applies TRIZ invention principle and evolution
pattern
Yasunori Nakao

TRIZ and I-TRIZ can be applied to various things and can be used as problem /problem solving, but it seems that it is difficult for new human resources to come in.
Therefore, people who aim to become entrepreneurs in the accelerator program(entrepreneur support program) that they were doing to start a business areinterested in TRIZ based on the idea idea, and think that they should enter theworld of TRIZ. Developed the tool. The idea idea tool (name: TOITOKU tool) also
applies the knowledge of TRIZ's invention principle and evolution pattern, andintroduces the development process and results of the tool.

Subcommittee）

Examination of TRIZ that is close to beginners and beginners－ With the fusion thinking of QFD and TRIZ operator－
Narumi Nagase（Japan TRIZ Society,Intellectual Property Creation Research Subcommittee）
At the Intellectual Property Creation Research Subcommittee, the recent slump in
the spread of TRIZ practice is regarded as a problem, and people in various
positions can be personalized by anthropomorphic thinking, or the opinions ofpeople they have met in the past can be reflected. Then, I looked at TRIZ negatively
and clarified the reason and cause of saying "I don't like TRIZ". Starting from theinformation of "I don't like TRIZ", I will utilize the thinking method of VOC generationof QFD (Quality Function Development) and the operator of I-TRIZ in a fusion
manner, especially targeting beginners and beginners of TRIZ. I examined
improvement measures such as spreading and promoting understanding of TRIZ.
The summarized policy proposal was disclosed to the members of the Intellectual
Property Creation Research Subcommittee, and although it was partial, preliminary
evaluations were also conducted before implementation, such as receiving opinionsin favor of the policy content. In this presentation, along with the introduction of themeasures, we will also disclose this thinking process, and in particular, introduce8the effectiveness of efforts by integrating methods for social issues.

It started in December 2017 on a volunteer basis, and constructed and publicized thePreliminary Edition of World WTSP Catalogs in October 2019.

The Beta Edition was pub

licized last year.
World WTSP Catalogs of TRIZ Sites were compiled with the manuscripts from 4 countries (i.e., Japan, Malaysia, China, and Russian Language Region) and from two internet
surveys (i.e., of the sites in the world and in USA).

And for supporti

ng these bottom-up activities, (3) we are working to do internet surveys of sites in9

individual countries.

The World WTSP Catalogs will certainly grow into a valuable and useful information source, for beginners, users, and experts all over the world (ofcourse including Japan).

Subcommittee）

About the process of TRIZ beginners becoming familiar with
TRIZ
Hiroki Ikegaya（Japan TRIZ Society,Intellectual Property Creation Research Subcommittee）

I hear that the boom of TRIZ in Japan has been about five years since it was
introduced in the Nikkei Mechanical magazine in 1997 as "super-invention" until
about 2002. Many companies abandoned the use of TRIZ and withdrew because it
was not as effective as expected. Why was TRIZ not fully utilized in Japan? (1) TRIZ
proficiency rate for beginners tends to remain low due to the difficulty of TRIZ itself.
(2) Organizational efforts are required, and there is difficulty in continuing. Isn't itpossible to think of the above? It is difficult and difficult to continue because TRIZ
requires an unhabitual thinking process. How can beginners establish TRIZ's nonhabitual thinking? In other words, how can engineers self-teach and self-teach TRIZ
thinking without relying on the organizational efforts of companies? I would like tointroduce my own learning efforts as a beginner and propose effective learning
methods for TRIZ.

Sachio Matsubara (Former professor at Kyushu University)

Transitions of Japanese manufacturing methods from theviewpoint of constructing and utilizing explicit and tacitknowledge:
the second report〜The win-win relationship between tacit knowledge and TRIZ〜

10

Sachio Matsubara (Former professor at Kyushu University)

The author presented a paper with the same title (the first report) at this symposium in
2009; this is the second report. The first report considered societal transition, comparing the twoeras of Japan’s Meiji Restoration and the period that began after the end of the Second World
War. The author hypothesized that tacit knowledge of the previous era disappears in 50 years
and that society will prosper when this tacit knowledge coexists with new explicit knowledge.
The first cycle, which began with the Meiji Restoration, shifted to the second cycle after
75 years. If the same logic is applied to the second cycle, which began at the end of the Second
World War, a transition to the third cycle should occur in 2020. Consistent with this premise,
major global cataclysmic events began in 2020. To make this imminent new era rich and fruitfuland so that it exists in harmony with the environment, it is necessary to be even more proactive
than before in incorporating the process of fostering tacit knowledge into education andproduction.
To achieve this aim, the current study leverages TRIZ as a tool for cultivating in-depth
tacit knowledge, examines tacit knowledge as an environment that maximizes the functions of
TRIZ, and considers the conditions for building a win-win relationship between the two.

tools (management-related contradiction matrix and invention principle,
evolution trend and evolution level, etc.) have been roughly prepared. We
selected several "models" from all aspects and analyzed (reverse) the
success factors in the TRIZ style. Then, at the 12th TRIZ Symposium(2016), the business model was specified as "LCC (Low Cost Carrier)
Model", and the framework of TRIZ style business model creation wasapplied to explore the evolutionary business model. At the 13th and 14th
TRIZ symposiums, we focused on specific tools and examined how to apply
the "evolutionary trends" proposed by Darrell L. Mann. This time, we will
explore the future trends of specific businesses centering on "evolution
trends" and present a method for identifying new functions (successfactors & competition factors) that should be satisfied in the future.
1． As an application method of "evolution trend", it is sublimated frompersonal application to a tool with some versatility.
2． We will analyze the factors that transform specific businesses in the
new corona disaster, explore business environment trends, andconduct case studies to build evolutionary business models.

Takuya Fujii（Japan TRIZ Society, Intellectual Property Creation Research Subcommittee）

Proposal of ideas for improving TRIZ symposium using
creative techniques
Takuya Fujii（Japan TRIZ Society,Intellectual Property Creation Research Subcommittee）

The TRIZ Symposium has a history of 17 times from the first in 2005 to this year,
and has been responsible for the spread and development of TRIZ and theexchange of TRIZ related parties as Japan's largest TRIZ event. However, in recent
years, while other thinking technologies such as design thinking and art thinking

12

have been whispered by the media and companies in Japan, it can be seen from thetendency of Google search results that the degree of attention to TRIZ is decreasing
year by year1). In line with this, the number of participants and presentations of the
TRIZ symposium is also declining, and it must be said that the spread of TRIZ in
Japan

is

currently

stagnant.

The

Intellectual

Property

Creation

Research

Subcommittee regards this as a "crisis of systematic TRIZ activities", and eachmember examines solutions to the problem of "TRIZ does not spread" using various
creative techniques such as TRIZ. I went to. In this presentation, we will focus on
the TRIZ symposium, which is the front line of the spread, development andexchange of TRIZ, and report the results of examining improvement ideas using
various creative techniques.

Kimihiko Hasegawa（Japan TRIZ Society, Intellectual Property Creation Research

Due to the influence of the new coronavirus infection, the symposium sponsoredby the Japan TRIZ Association last year was canceled, and it is expected that thisyear's symposium will be held on a small scale. Meanwhile, the Intellectual Property
Creation Research Subcommittee has no direct relationship with the newcoronavirus infection, but in view of the recent slump in the number of participantsin events hosted by the Japan TRIZ Association. , It was decided to consider
measurestopopularize

activities

inJapanesecompanies

and

other

organizations. However, even in the IP Creation Research Subcommittee, it wasdifficult to have lively discussions on such a big theme in the environment of Web
conferencing, and it was difficult to combine research activities for a specificpurpose into one result. It was decided that each person would consider andannounce the measures to be considered in their respective fields of specialization.

13

Therefore, from the standpoint of working as a consultant for the TOC thinking
process in addition to the TRIZ consultant, I analyzed the current situation of TRIZ's
organizational activities, and based on the results, I learned anew about how topromote TRIZ's organizational activities. I decided to propose a new method (ideatool for innovation).

In 2016, we established a special club "Intellectual Property TKY (Terakoya)" with theaim of fostering value-creating future industrial human resources who will be
responsible for Society 5.0. Taking advantage of regional characteristics, through thechallenge of the real thing with TRIZ as a weapon, we will discover problems, create
ideas, and challenge solutions. In particular, we are practicing Education-TRIZ's "Tongs
model", which states that we will nurture solutions to technical problems by
understanding ideals and reality and clarifying the differences. The main activities are
as follows. (1) Challenge the F1 course at Suzuka Circuit with the KV-BIKE, a battery
bicycle with 40 rechargeable AA batteries. (2) Deep sea survey of Suruga Bay utilizing
the regional characteristics of Suruga Bay (2500m deep sea), which is the deepest inJapan (3) Program robot classroom using 3D blocks with the theme of regional
characteristics In 2020, it was a corona wreck, but in order to express the charm of
the deep sea, a life-sized model of coelacanth, which is said to be a "fish that calls forhappiness," was realized with 11,000 blocks for teaching materials. I wanted to freely
shape what I thought, but I challenged the technical contradiction that strength isrequired with the invention principle of TRIZ, and also experienced practically that"value" is created in the work.
