Outline• The promotion activity of TRIZ was started in 2005.
– Hitachi Ltd. was already started the activity as HiSPEED21
in 1999.
• http://techon.nikkeibp.co.jp/article/NEWS/20050224/102048/
HiSpeed21:Hitachi Innovation Program toward Super Process with Excellent Engineering & Digital Technologies for the 21st Century• The object people are engineers of the R & D and theproduct development.
• Promotion and spread activity through in-houseseminar– As for beginners, the seminar is executed centering on theusage of the contradiction matrix.
• There is a hurdle at the stage where the technological parameter of_/_/_/
the product development ties to the parameter of the contradiction_/_/
matrix.

Point of case

"Clarification of problem by KT method and Idea creation
for problem solving by TRIZ"– On every new 3.5"HDD, the data destruction rate by the scratch isgetting higher and higher. The scratch problem was analyzed by the KTmethod (PA : Problem Analysis) as the first step.
• It was found that the air spoiler (mechanical parts) caused the particle
generation which made scratches.
KT-PA : Kepner Tregoe Problem Analysis
KT method: Registered trademark of United States Kepner Tregoe Co. Japanese branch– The particle injection test with HDD was executed based on assumptionof not accumulating contamination easily because Karman vortex did notoccur easily by changing shape of the air spoiler.
• The effect was confirmed.

– To become larger, and to obtain higher reliability, next generation's airspoiler’s design was worked out by TRIZ.
• The psychological inertia was broken down by using TRIZ.

Outline• Air pressure equipment comprehensive manufacturer that
handles it from development and production to sales– 750 employees– 300,000 products– The engineers should work for not only product development but also acting in cooperation
with the marketing, sales, production and the procurement sections.

• Introduction at beginning in October, 2006
– Promotion and the introduction are aimed at in order of QFD→TRIZ→TM.
– http://techon.nikkeibp.co.jp/article/FEATURE/20101122/187539/
QFD: Quality function deployment (Quality Function Deployment)
TM: Taguchi method/quality engineering (Taguchi Methods/Quality Engineering)• The seminar schedule and the development schedule are madesynchronous.
– A new product was out as the result (= profit) in three years, and confirmed validity.
– Two high-speed port valve as a new product was released in July, 2009.

Point of case

"Introduction of TRIZ that aims at establishment ofabsolute strong point and the background"– Decision of introducing TRIZ was based on analysis ofproblems concerning the introduction to the company andcountermeasures against the problems.
– Introduction and use of tool, technique and software that canbe worked in conjunction with TRIZ
• Mind Map, TOC, and the Kano model, etc. was used.
TOC: Constraint theory (Theory of Constraints)
Mind Map is registered trademarks of The Buzan Organisation– The process until it achieves the results was requested toone consultant.
• Customer request and development target setting by QFD• Breakthrough of existing technology by TRIZ
• Optimum design and design verification by TM

Outline• The promotion activity was started in 2006.
– The propeller attended outside seminar related to TRIZ, andthe essence was fed back in in-house seminar.

• The object people are engineers in R & D section.
– The activity of creating ideas for solving the problem in theirtopics.

• It was promoted such as a half a day workshops andthe TRIZ patent excavation meetings.
– An original tool that explained principle with the case was
made, and it can be used in intranet.
– The activity that specialized in the problem definition_/_/_/and the idea creation.

Point of case

"Point of TRIZ promotion activity in research"– Details of promotion activity– Content of activity of promotion• It was introduced by three steps.
• An original tool can be used in intranet.

– Promotion program• ARIZ and USIT were combined and modified for engineers to use.

Summary of introduction cases•

There are propellers in the companies, and they promote TRIZ.
– They realize the advantage of TRIZ, and they promote to apply TRIZ positively.

•The propeller is supporting the problem analysis, modeling andmultipronged approaches.
– Creating ideas are not only to solve current problems but also to anticipate
further problems which will be occurred when the idea is realized.

•The propellers combine TRIZ with other techniques.
– They improve each technique for engineers to use it easily.

Case of Hyundai-Kia Motors in South Korea:• Title– Concept Development of a Variable Compression Ratio
Engine Using TRIZ
• by Mr. Hong-Wook Lee in 2010

– Point of case• Obtaining the concept of the variable compression ratio engine of themultilink type for patent circumvention– The development object was decided by the benchmarking.
– A lot of tools of TRIZ were applied and the idea was created for patentcircumvention.

Case in South Korea• There is a sign of change in applying TRIZ
with leading by consultants.
– People are learning TRIZ and applying TRIZ
by themselves.
– POSCO established TRIZ university and they
are spreading TRIZ systematically.
