  • Transcript

    • 1. WHAT IS “TRIZ” ?
      • A Russian acronym for
      • T eoria R esheneya I sobretatelskih Z adach
      • ( Theory of Inventive Problem Solving)
    • 2. 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.
    • 3. 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
    • 4. BASIC CONCEPTS
      • Systems evolve toward IDEALITY irreversibly
      • Resolving CONTRADICTIONS as they evolve
      • PATTERNS OF INVENTIONS/OPERATORS are constantly recognized and used
    • 5. THINKING OUTSIDE YOUR PARADIGM SPACE TIME POSSIBLE IMPOSSIBLE EVENTS AND EXPERIENCES SHAPE OUR BELIEF SYSTEM!!!
    • 6. Mechanical Effects & Technology Electrical & Magnetic Effects & Technology Chemical Effects & Technology Thermo-Dynamics P roblem S olution THE SOLUTION SPACE ®Ideation International, used by permission
    • 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. 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
    • 9. 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
    • 10. Modern TRIZ is complex - It involves many tools
      • 40 Inventive principles
      • Function Analysis (FA)
      • Inventive Standards
      • ARIZ (Algorithm of Inventive Pr. Solving)
      • Su-Field Modeling (SFM)
      • Root-Conflict Analysis (RCA+)
      • Reverse TRIZ
      • Catalogue of Effects
    • 11. OPERATORS
      • Abstract problem Abstract solution
      • Specific problem Specific solution
    • 12. AN OPERATOR
      • Operator Example
      • Specific problem Specific solution
      • 3x 2 +5x+2 = 0 x = ????
    • 13. AN OPERATOR
      • Operator Example
      • Specific problem Specific solution
      • 3x 2 +5x+2 = 0 x= -1, -2/3
      • Trial and Error!!
    • 14. AN OPERATOR--THE BASIC PRINCIPLE OF TRIZ
      • Operator Example
      • Abstract problem Abstract solution
      • ax 2 +bx+c = 0 x=(-b+/-  b 2 -4ac )/2a
      • Specific problem Specific solution
      • 3x 2 +5x+2 = 0 x= -1, -2/3
      • TRIZ DOES FOR PROBLEM SOLVING AND FORECASTING WHAT ALGEBRA DOES FOR EQUATION PROBLEM SOLVING
    • 15. Problem: Remove cores from a million of sweet peppers…. INNOVATION-TRIZ,INC.
    • 16. Processing Sweet Peppers PATTERNS OF INVENTION ®Ideation International, used by permission
    • 17. WHAT IS THE OPERATOR?
      • “ Slowly raise pressure and suddenly reduce it”
      • OR
      • “ accumulate energy and suddenly release it”
      • A path to a solution
      • A solving approach
      • A direction towards an answer

    • 19. 1 2 3 4 5 6 7 8 9 n My Solution To Corresponding Solutions Many Typical Problems Many Typical Recommendations for Solutions (Knowledge base) A large number of typical problems are available for consideration TRIZ help to marrow the search to a manageable range of typical problems For each typical problem, there are one or more potential solutions Prism of TRIZ - Analytical tools ®Ideation International, used by permission 1 2 3 5 6 7 8 9 n 4 My Problem
    • 20. Triz is both a mental process and a science, as well as a selection of tools in a tool kit
    • 21. 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
