WHAT IS “TRIZ” ? A Russian acronym for T eoria R esheneya I sobretatelskih Z adach ( Theory of Inventive Problem Solving)

A Russian acronym for

T eoria R esheneya I sobretatelskih Z adach

( 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.

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 TRIZ Genrich Altshuller 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 Key Discoveries Are Mined for… * Today, the followers of Altshuller have analyzed / investigated over 2,800,000 patents 200,000+ Analysis of Patents* 40,000 Innovative Patents Synthesized down to just Innovative Patents

Problems & solutions were repeated across industries & sciences  Principles for solving Problems

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

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

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. Ideality = All Useful Functions All Harmful Functions WHAT IS IDEALITY? ®Ideation International--used by permission
