    1. 1. WHAT IS “TRIZ” ? <ul><li>A Russian acronym for </li></ul><ul><li>T eoria R esheneya I sobretatelskih Z adach </li></ul><ul><li>( Theory of Inventive Problem Solving) </li></ul>
    2. 2. THE HISTORY OF TRIZ <ul><li>A discovery of a talented patent examiner for the Russian navy, Genrich Altshuller, 1950’s </li></ul><ul><li>Originated from the study of several hundred thousands of the world’s most inventive patents--now in millions </li></ul><ul><li>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 </li></ul><ul><li>Altshuller recognized that problem solving principles are predictable and repeatable-- anyone can invent! </li></ul><ul><li>Altshuller established schools to teach after a Stalin 7 yr. prison term— </li></ul><ul><li>Altshuller deceased in 1998 at 71 years. </li></ul>
    3. 3. Origin of TRIZ Genrich Altshuller <ul><li>Problems & solutions were repeated across industries & sciences  Principles for solving Problems </li></ul>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
    4. 4. BASIC CONCEPTS <ul><li>Systems evolve toward IDEALITY irreversibly </li></ul><ul><li>Resolving CONTRADICTIONS as they evolve </li></ul><ul><li>PATTERNS OF INVENTIONS/OPERATORS are constantly recognized and used </li></ul>
    5. 5. THINKING OUTSIDE YOUR PARADIGM SPACE TIME POSSIBLE IMPOSSIBLE EVENTS AND EXPERIENCES SHAPE OUR BELIEF SYSTEM!!!

    7. 7. 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
    8. 8. PARALLEL UNIVERSES <ul><li>Many industries or technologies face the same generic type of design problems. </li></ul><ul><li>It’s almost impossible to cope with all areas of technology, read all literature,…. </li></ul><ul><li>Accidents or alerts sometimes change this </li></ul><ul><li>It is helpful to be aware of problem solving principles used by everyone </li></ul>
    9. 9. TRIZ Philosophy <ul><li>Systems evolves through elimination of contradictions </li></ul><ul><ul><li>Problems are be represented in terms of contradictions that must be eliminated to come up with breakthrough solutions. </li></ul></ul><ul><li>Evolution of systems is a systematic process </li></ul><ul><ul><li>A number of regularities exist which govern the technology evolution. The regularities are generic over various domains. </li></ul></ul><ul><li>Previous experience can be studied and re-used </li></ul><ul><ul><li>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. </li></ul></ul><ul><li>New inventive problems are hard to formulate correctly </li></ul><ul><ul><li>A task is to build the most correct problem formulation . </li></ul></ul><ul><li>Successful problem solving requires a blend of generic thinking and specific knowledge </li></ul>
    10. 10. Modern TRIZ is complex - It involves many tools <ul><li>40 Inventive principles </li></ul><ul><li>Function Analysis (FA) </li></ul><ul><li>Inventive Standards </li></ul><ul><li>ARIZ (Algorithm of Inventive Pr. Solving) </li></ul><ul><li>Su-Field Modeling (SFM) </li></ul><ul><li>Root-Conflict Analysis (RCA+) </li></ul><ul><li>Reverse TRIZ </li></ul><ul><li>Catalogue of Effects </li></ul>
    11. 11. OPERATORS <ul><li>Abstract problem Abstract solution </li></ul><ul><li>Specific problem Specific solution </li></ul>
    12. 12. AN OPERATOR <ul><li> Operator Example </li></ul><ul><li>Specific problem Specific solution </li></ul><ul><li>3x 2 +5x+2 = 0 x = ???? </li></ul>
    13. 13. AN OPERATOR <ul><li> Operator Example </li></ul><ul><li>Specific problem Specific solution </li></ul><ul><li>3x 2 +5x+2 = 0 x= -1, -2/3 </li></ul><ul><li>Trial and Error!! </li></ul>
    14. 14. AN OPERATOR--THE BASIC PRINCIPLE OF TRIZ <ul><li>Operator Example </li></ul><ul><li>Abstract problem Abstract solution </li></ul><ul><li>ax 2 +bx+c = 0 x=(-b+/-  b 2 -4ac )/2a </li></ul><ul><li>Specific problem Specific solution </li></ul><ul><li>3x 2 +5x+2 = 0 x= -1, -2/3 </li></ul><ul><li>TRIZ DOES FOR PROBLEM SOLVING AND FORECASTING WHAT ALGEBRA DOES FOR EQUATION PROBLEM SOLVING </li></ul>
