INTRODUCTION

It is a way of accessing existing excellence in problem

solving.

Uncover the generic problem that lies behind the

specific problem

Providing a generic solution to generic problem

Interpreted in terms of the original specific problem

HISTORY

Genrich S. Altshuller born in 1926.

Serving in the Soviet Navy as a patent

expert in the 1940s

Over 90% of the problems faced by

inventors had been solved in

various technical fields

He categorized the patent solutions

into five levels

Level 1: Routine design problems (32%)

Level 2: Minor corrections (45%)

Level 3: Fundamental improvements (18%)

Level 4: New generations (4%)

Level 5: New system(less than 1%)

THEORY OF INVENTIVE PROBLEM SOLVING

This method consists of Three major principles

The Resolution of Technical and Physical Contradictions The Evolution of Systems The Ideal System and Ideal Solution

Triz example: Umbrella

• Step 1. Identifying the Problem• Step 2: Formulate the problem• Step 3: Formulate an ideal solution• Step 4: Look for Analogous Solutions

ADVANTAGES

Objective, domain- independent laws of evolution of technical systems have been disclosed and guide the design process.

Triz provides systematic access to the previous experience of many generations of inventors.

Triz proposes a structured and ergonomic shape of scientific phenomena and effects.

Triz does not replace human creativity but restructures the thinking process of a designer.

DISADVANTAGES

Long term education. Inventive principles and Inventive standards are

sometimes far from a technical solution to a given problem.

Necessity to reformulate the initial problem in terms of generalized parameters (contraction model).

CONCLUSION

TRIZ has been used for creative solving not only in technological fields but also in nontechnical fields, like services and business. It also has rich experience (in Russia) in the field of creativity education. TRIZ is expected to give great impact on innovation in all these fields in Japan and in the world.
