Triz Basics -Product Design & Development

WHAT IS “TRIZ? ”

A Russian acronym for

Teoria Resheneya Isobretatelskih Zadach

(Theory of Inventive Problem Solving)

THE HISTORY OF TRIZ• A discovery of a talented patent examiner for the Russian navy,

Genrich Altshuller, 1950’s• Originated from the study of several hundred thousands of the

world’s most inventive patents--now in millions• Altshuller recognized that the development of technological

systems follows predictable patterns that cut across all areas of technology--the speed of technical evolution can be accelerated

• Altshuller recognized that problem solving principles are predictable and repeatable--anyone can invent!

• Altshuller established schools to teach after a Stalin 7 yr. prison term—

• Altshuller deceased in 1998 at 71 years.

Origin of TRIZOrigin of TRIZGenrich Altshuller

* Today, the followers of Altshuller have analyzed / investigated over 2,800,000 patents

200,000+

Analysis of Patents*

40,000

Synthesized down to just Innovative Patents

1. Problems & solutions were repeated across industries & sciences Principles for solving Problems

2. Patterns of technical evolution were repeated across industries & sciences Technology Trends to evolve a technical system to the next generation

3. Innovations used scientific effects outside the field from where the original problem was found Scientific Effects can be used to solve problems in unique ways

BASIC CONCEPTS

• Systems evolve toward IDEALITY irreversibly

• Resolving CONTRADICTIONS as they evolve

• PATTERNS OF INVENTIONS/OPERATORS are constantly recognized and used

PARALLEL UNIVERSES

• Many industries or technologies face the same generic type of design problems.

• It’s almost impossible to cope with all areas of technology, read all literature,….

• Accidents or alerts sometimes change this

• It is helpful to be aware of problem solving principles used by everyone

TRIZ Philosophy

• Systems evolves through elimination of contradictions– Problems are be represented in terms of contradictions that must

be eliminated to come up with breakthrough solutions.• Evolution of systems is a systematic process

– A number of regularities exist which govern the technology evolution. The regularities are generic over various domains.

• Previous experience can be studied and re-used – By studying previous experience of creative work it is possible to

learn how to use this experience in a systematic way to solve new problems.

• New inventive problems are hard to formulate correctly– A task is to build the most correct problem formulation.

• Successful problem solving requires a blend of generic thinking and specific knowledge

Modern TRIZ is complex - It involves many tools

Triz is both a mental process and a science, as well as a selection

of tools in a tool kit

The ideal system performs a required function without actually existing. The function is often performed using existing resources. ALL systems evolve in this direction over time by resolving contradictions.

Problem 1

• How to protect orange plants from monkeys?

Solution

Lemon = modification of monkeys.

Problem 2

• How to protect the hydraulic foil from being damaged by cavitations?

Solution

• Ice = modification of water.
