  1. Creative Problem Solving TRIZ

  2. Problem Solving Methods • DMAIC – Define, Measure, Analyze, Improve, Control • DFSS – Design for Six Sigma • PDCA – Plan, Do, Check, Act • PDSA – Plan, Do, Study, Act • TQM, PR, Kaizen, Pugh, WB, . . . . • TRIZ – Theory of Inventive Problem Solving

  3. TRIZ Principles • Somebody, someplace, has already solved your problem or one similar to it. Creativity means finding that solution and adapting it to the current problem. • Don't accept compromises. Eliminate them.

  4. Somebody has Solved Your Problem • California Dairy Farmers needed a way to dry manure • Heat became too expensive • Solution – hydrophilic gas which carries water away • Orange Juice Concentrate

  5. Somebody has Solved Your Problem • Pharmaceutical industry needed a way to deal with excess foam from a pharmaceutical process • Solution came from the beer industry • Paint manufacturers needed a way to deal with sludge accumulation in equipment • Solution came from nuclear waste disposal industry

  6. Traditional Tradeoffs • Technical Contradictions • Stronger at cost of additional weight • Greater bandwidth requires more power • Faster airbag deployment requires greater force • Physical Contradictions • Coffee hot enough to enjoy but not so hot as to burn • Software powerful features but easy to use • Surveillance quick to target but slow to collect data

  7. TRIZ • Tries to eliminate problems rather than accept compromise • Airbag material that can’t grab skin as it is deployed • Car supersystem to avoid crashes • Social system that prevents small persons from front seat • Match book problem – dissolving • Compromise when necessary

  8. TRIZ Dissolution Technical Constraints • Technical contradictions solved through 40 problem solving principles • Physical contradictions solved through 4 basic principles to look at supersystems, subsystems, separation of time, space, etc.

  9. Self-heating Beverage Container • Contradictions • Fast heating can cause steam pressure to rupture capsule • Thin material allows heat transfer but isn’t strong enough • Multiple thin layers strong enough but too expensive • Metal top will allow traditional pop top but can burn lips

  10. Self-heating Beverage Container Principle 1 – segmentation, instead of blow molding container, satisfy layer requirement through die stamping operation

  11. Self-heating Beverage Container

  12. Improve Direct Mail Advertising • Customer wants knowledge of product, but doesn’t want to read • Advertiser wants response to ads, but only from customers who are serious • TRIZ led to techniques used in diet food industry and applied to patio building

  13. Resources • http://www.triz-journal.com/ • http://triz40.com/ • 40 Principles

  14. TRIZ Matrix - Example • want to increase length but not add to the weight
