Jeongho Shin, ‘How to learn TRIZ with ease and fun’, The 8th TRIZ Symposium in Japan1

Abstract
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, mostof 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 theTRIZ 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 ContradictionModeling) has been developed for easy modeling of contradictions using a diagram thatconsists of 5 components. A user can easily describe contradictions and explain to otherswith 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 togenerate ideas like playing. It is illustrated that easy and funny approaches can be utilized
as good instruments for training TRIZ beginners.

* The SCM diagram and the Invention song have been firstly introduced in TRIZ Future conference 2011 withthe title of ‘Development and Application of the Simple Contradiction Modeling and the Invention Song’.

Contradiction

It is too difficult to understand and model itas a beginner

40 Invention
Principles

I learned all 40 invention principles, but
forgot all except ‘Segmentation’.

Components of SCM diagram
Element(its property)•••

Located at the center of the diagram
Indicate a tool or its property that can be in two states.
Directly interacts with the result to achieve

State A••

Located at the top of the diagram
Indicate one of two opposite states of Element

State non-A••

Located at the bottom of the diagram
Indicate the other of two opposite states of Element

Positive Result 1••

Located at the left side of the diagram
Indicate the result or product that can be achieved, if the Element is in State
A

Positive Result 2••

Located at the right side of the diagram
Indicate the result or product that can be achieved, if the Element is in Statenon-A•

The ‘+’ mark in the diagram means improving and the ‘-’ mark meansworsening
The arrow denotes the flow of problem modeling.

Deriving Contradictions
 TC : Technical Contradiction
 PC : Physical Contradiction

TC 1

Ideal Question 1If (Element or its property) is in (State A),Then (Positive Result 1) is improved,But (Positive Result 2) is worsened.

TC 2

Although (Element or its property) isin (State A),(Positive Result 2) can be improved. How ?

Ideal Question 2

If (element or its property) is in (State non-A),
Then (Positive Result 2) is improved,
But (Positive Result 1) is worsened.

Although (Element or its property) isIn (State non-A),(Positive Result 1) can be improved. How?

PC(Element or its property) has to be in (State A) for (Positive Result 1)
and has to be in (State non-A) for (Positive Result 2).
