Triz Basics -Product Design & Development - Presentation Transcript
WHAT IS “TRIZ” ?
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.
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
BASIC CONCEPTS
Systems evolve toward IDEALITY irreversibly
Resolving CONTRADICTIONS as they evolve
PATTERNS OF INVENTIONS/OPERATORS are constantly recognized and used
THINKING OUTSIDE YOUR PARADIGM SPACE TIME POSSIBLE IMPOSSIBLE EVENTS AND EXPERIENCES SHAPE OUR BELIEF SYSTEM!!!

TAPPING OUR KNOWLEDGE All Science INDUSTRY COMPANY PERSONAL 1 2 3 4 5 All That Is Knowable NOTE: BRAINSTORMING, ETC. FOCUS ONLY ON USING THE INNER AREA MORE EFFECTIVELY
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 DOES FOR PROBLEM SOLVING AND FORECASTING WHAT ALGEBRA DOES FOR EQUATION PROBLEM SOLVING

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
