Triz Basics -Product Design & Development 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!!!
  • Mechanical Effects & Technology Electrical & Magnetic Effects & Technology Chemical Effects & Technology Thermo-Dynamics P roblem S olution THE SOLUTION SPACE ®Ideation International, used by permission
  • 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
    • 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
  • OPERATORS
    • Abstract problem Abstract solution
    • Specific problem Specific solution
  • AN OPERATOR
    • Operator Example
    • Specific problem Specific solution
    • 3x 2 +5x+2 = 0 x = ????
  • AN OPERATOR
    • Operator Example
    • Specific problem Specific solution
    • 3x 2 +5x+2 = 0 x= -1, -2/3
    • Trial and Error!!
  • 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
  • Problem: Remove cores from a million of sweet peppers…. INNOVATION-TRIZ,INC.
  • Processing Sweet Peppers PATTERNS OF INVENTION ®Ideation International, used by permission
  • 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
    • Removing shells from sunflower seeds
    • Cleaning filters
    • Unpacking parts wrapped in protective paper
    • Splitting diamonds along micro-cracks
    • Producing sugar powder from sugar crystals
    PATTERNS OF INVENTION
  • 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
  • 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

    • Lemon = modification of monkeys.
  • Problem 2
