  4. 4. The Benefit of DFSS Innovation • The time advantage of innovation Improvements / Value Companies using Continuous Improvement & Continuous Innovation Competition using only Time Continuous Improvement Advantage Time @QAI
  5. 5. Develop Design Concepts Left Brain Right Brain •Functionality (FMEA) •Brainstorming •TRIZ •Brain writing •Trend Analysis •Assumption Busting •Statistical Analysis •How lucky are you? @QAI
  6. 6. Idea Generation Techniques • Modified Brainstorming • Brainwriting • Assumption Busting • TRIZ @QAI
  7. 7. TRIZ Projects frequently reach a point where the analysis is completed and the team is at a point where it is unclear where they need to go for resolution. This applies not only to projects but to problem solving, root cause analysis, or even Six Sigma (upon completion of the analysis phase). The project team must be creative in order to determine what to do next. TRIZ minimizes the chance of unpredictable and unrepeatable results that are associated with brainstorming or brainwriting. @QAI
  8. 8. TRIZ • TRIZ is based on the idea that many of the underlying “root” problems that engineers face today contain elements that have already been solved (approximately 90%), often in a completely different industry, for a totally unrelated situation, that uses an entirely different technology. @QAI
  9. 9. TRIZ • The most important recognition is that “technical systems evolve” – Which evolves towards the increase in ideality • By overcoming Contradictions –Achieved primarily with the minimal introduction of resources @QAI
  10. 10. T.R.I.Z. (Trez or trees) Theoria Resheneyva Isobretatelskehuh Zadach Theory of Inventive Problem Solving – Developed after WWII (1946) by Genrich Atschuller (1926-1998), a Russian inventor and naval officer. He was sent to the Siberian Gulag camp by Stalin for thinking too much. He was released from prison after Stalin’s death. – Based on a theory that there are universal principles of inventive and creativity. – TRIZ is structured method that can be used to rapidly generate plausible concepts that solve problems in technical and non-technical domains. @QAI
  11. 11. Altschuller / T.R.I.Z. • Started with 400,000 patients, today it includes the study of more than 2.5 million patients. • Altschuller discovery: – Each innovative patient solves a technical problem, but across domains, there are common solutions. These solutions were boiled down to 40 principles. – Inventive problems often carry with them inherent contradictions. (e.g. stronger, but heavier) – Anyone can use this knowledge and methodology to solve problems. @QAI – Resources are often idle during problem solving.

  13. 13. TRIZ Method Understand the problem as a system Locate conflicts Identify Resources Systematically explore solution @QAI
  14. 14. TRIZ Thus; @QAI
  15. 15. The Three Premises of TRIZ • Ideality (ideal solution) • Resolve Contradictions • System Approach TRIZ Approach/Tools • Innovation Situation Questionnaire (ISQ) • Problem formulator • Substance-Field Analysis (Su-Field) @QAI
  16. 16. Why TRIZ ? • Simply stated, we need to create innovative products and services to remain competitive ! – We need to significantly improve the engineers ability to quickly solve difficult and seemingly impossible engineering problems which often lead to next generation “innovative” products. Creative Problem Solving! Provides a Dialectic Way of Thinking! @QAI
  17. 17. The Innovation Lever TRIZ Knowledge Industry Knowledge Company Knowledge Your Knowledge Innovative Solutions @QAI
  18. 18. Example • Generic problem solving, think in broad terms: – Principle #3 Local Conditions / Quality – Airport with smoking areas – Yard light with a photocell – Pen with an eraser • Combine several techniques and tools to enhance problem solving @QAI
  19. 19. Altschuller Contradiction to solve • The 40 Inventive Principles can be utilized Matrix problems but unfortunately, fixing one problem often results in creating another problem. Examples: – Companies buy other companies to grow and strengthen themselves. This often results in a company disorganized and less stable. – Coffee should be hot for enjoyable drinking but cool enough to prevent burning the drinker. – Bandwidth increases (Good) but requires more power (bad) – Training increases competence (Good) but requires employees to be away from their job responsibilities (bad). • These contradictions can be resolved by applying the Contradiction Principles in a Contradiction Matrix. @QAI
  20. 20. Altschuller Contradiction Matrix As you can see from the examples on the previous slide there are two categories of contradictions. 1. Technical contradictions are based on classical engineering of “trade-offs.” The desired state can not be obtain because there is a barrier in the system. 2. Physical contradictions (Inherent) are situations in which one object or system contradicts the requirements of the other. @QAI
  21. 21. Contradiction Principles 1. Weight (of object in motion) 21. Shape 2. Weight (of stationary object) 22. Stability 3. Length (of object in motion) 23. Strength 4. Length (of stationary object) 24. Power 5. Area (of object in motion) 25. Losses of energy 6. Area (of stationary object) 26. Losses of substance 7. Volume (of object in motion) 27. Losses of Information 8. Volume (of Stationary motion) 28. Losses of Time 9. Speed 29. Quantity of Substance 10. Force or Intensity 30. Reliability 11. Stress or Pressure 31. Measurement Accuracy 12. Use of Energy (of object in motion 32. Manufacturing Precision 13. Use of Energy (of stationary object) 33. Harmful external effects 14. Duration of Action (of object of motion) 34. Ease of manufacturing 15. Duration of Action (of stationary object) 35. Ease of operation 16. Temperature 36. Ease of repair 17. Illumination intensity 37. Adaptability or versatility 18. Difficulty in monitoring or measuring 38. Device complexity 19. Productivity 39. Extent of automation 20. Object generated harmful effects @QAI
  22. 22. Contradictions Contradictions appear first as a gap between demands and supplies. They are overcome by break-through inventions. These inventions form the micro-steps of evolution in technical systems. Since the solutions are not known, creative problem solving is the method utilized to overcome contradictions. @QAI
  23. 23. Contradiction Matrix • Are a result of Altschuller’s patent research • The principles are technical characteristics • Can be applied throughout the Six Sigma DMADV process whenever conflicts or contradictions arise. • It is a large table that link pairs of the engineering principles (39 X 39 matrix). @QAI
  24. 24. Contradiction Matrix W orsening Feature W eight of W eight of Length of Length of moving stationary moving stationary object object object object Improving Feature W eight of moving object 32, 21 12, 5 – W eight of stationary object 32, 21 – 6,9, 23,31 Length of moving object 12, 5, 34 – 1, 5 Length of stationary object – 6,9, 23,31 1, 5 Inventive Principle that can be utilized to identify a solution @QAI
  25. 25. Contradiction Matrix The core process is to drive a physical contradiction (using the matrix) and solve it with the Separation Principle. Once the physical contradiction is determined this solution technique is powerful enough to identify break-through (innovative) solutions. @QAI
  26. 26. TRIZ TRIZ works and is used by large as well as small organizations on several levels to solve real, practical everyday problems. TRIZ is utilized at companies such as Ford, Motorola, Proctor & Gamble, Eli Lilly, 3M, LG and … @QAI
  27. 27. Summary Innovative concepts are critical and a necessity to drive the optimization efforts to design new products or redesign exsisting processes or products. @QAI
