  11. 11. Not Exactly ! TRIZ AK Dhamija people reject good solutions and invest in bad ones because because they do not know the difference between them. Introduction Evolving People can take one of two positions Pattern Why new • It is not possible to know whether the idea is good or bad when it is first proposed. theory ? • Because the same patterns are repeated, we can learn from the past to get better solutions today. Good Solutions TRIZ - new paradigm TRIZ There is growing evidence supporting position 2, using TRIZ to provide the general theory of the evolution of Methodology good ideas. TRIZ concepts Contradiction Common Features of Good Solutions Resources Ideal final result Patterns of • Resolves contradictions evolution • Increases the ”ideality” of the system Innovative Principles • Uses idle, easily available resources Contradiction Matrix References AK Dhamija, DIPR, DRDO TRIZ, An Introduction 11/57

  25. 25. Contradiction TRIZ AK Dhamija Difficult Problems Contain Contradictions Introduction Evolving Pattern A contradiction is a conflict in the system. A system consists of two Why new components: tool (T) and object (O) theory ? Good Solutions Ax blade to cut wood TRIZ - new paradigm • The edge of the ax blade,is a tool that splits the object, a chunk of wood TRIZ Methodology • If you make the blade heavier, the ax can strike a more effective blow, but it becomes more awkward to handle TRIZ concepts Contradiction A company wants to improve customer service by increasing staff training Resources Ideal final result Patterns of • Training is the T that is used to improve a certain O: the professional quality of employees evolution Innovative • For better service, more training time is needed but the time loss might be intolerable Principles Contradiction Matrix References AK Dhamija, DIPR, DRDO TRIZ, An Introduction 25/57
  26. 26. The seesaw analogy of the problem situation TRIZ AK Dhamija Introduction Evolving Pattern Why new theory ? Good Solutions TRIZ - new paradigm TRIZ Methodology TRIZ concepts Contradiction Resources Ideal final result Patterns of evolution Innovative Principles TRIZ advises us NOT to avoid contradictions Contradiction Matrix • It reverses the logic - find the contradiction, intensify it References and resolve it without compromise • Contradictions between tools and objects are the moving AK Dhamija, DIPR, DRDO TRIZ, An Introduction 26/57
  27. 27. Resources TRIZ Using resources, one can remove the contradiction and get the ideal AK Dhamija final result Introduction Evolving Resources are things (including waste), information, energy, or Pattern properties of the materials that are already in or near the Why new theory ? environment of the problem Good Solutions TRIZ - new paradigm Resource has the functional and technological ability to jointly TRIZ perform additional functions Methodology TRIZ Ax blade to cut wood concepts Blade, its edge, form, material, and other properties; the handle and its properties; the chunk of wood and its Contradiction properties; the surrounding air; the person; etc. Resources Ideal final result Patterns of evolution A company wants to improve customer service by increasing staff training Innovative Principles The curriculum, its structure and properties, skills of teachers, textbooks, the motivation, and existing Contradiction knowledge and skills of the students are all resources, as well as the culture of the company and the physical Matrix environment of the training References AK Dhamija, DIPR, DRDO TRIZ, An Introduction 27/57
  28. 28. Resources to resolve contradiction TRIZ Resources AK Dhamija Introduction Evolving Pattern Resources are often invisible at Why new first because we are accustomed theory ? to not seeing them Good Solutions TRIZ - new paradigm TRIZ Methodology TRIZ Sea saw as ideality concepts Contradiction Resources Ideal final result Patterns of If resources included some rope, a evolution Innovative tree, and a strong parent, both Principles Contradiction ends of the plank could go up at Matrix the same time References AK Dhamija, DIPR, DRDO TRIZ, An Introduction 28/57

  30. 30. Ideal final result TRIZ If the child’s resources included some rope, a tree, and a strong AK Dhamija parent, both ends of the plank could go up at the same time Introduction Evolving Pattern Ax blade to cut wood Why new theory ? • Something changes the ax in some way so that it is both heavy and light, for the double purpose of Good Solutions making the blow stronger without decreasing the ease of use TRIZ - new paradigm • Hollow Handle : Air is used as the resource that solves the problem TRIZ Methodology • The center of gravity moves nearer to the blade. The blow is more powerful, which could be thought of as heavy, although the tool is lighter. TRIZ concepts Contradiction A company wants to improve customer service by increasing staff training Resources Ideal final result Patterns of • Changing the training so that part of it is done on the job, not in the classroom evolution Innovative • Better learning as well as shorter classes, because the students can see the results immediately and Principles are in a better position to apply them Contradiction Matrix • Improves both motivation and feedback References AK Dhamija, DIPR, DRDO TRIZ, An Introduction 30/57
  31. 31. Resources to resolve contradiction and achieve Ideality TRIZ AK Dhamija Introduction Evolving Pattern Why new theory ? Good Solutions TRIZ - new paradigm TRIZ Methodology TRIZ concepts Contradiction Resources Ideal final result Patterns of evolution Innovative Principles Contradiction Matrix • Ideality is the measure of how close the system is to the ideal final result References • If the useful feature improves, the ideality improves • If the harmful feature lessens, the ideality improves AK Dhamija, DIPR, DRDO TRIZ, An Introduction 31/57
  32. 32. Ideality TRIZ AK Dhamija Introduction Evolving Pattern Why new theory ? Good Solutions TRIZ - new paradigm Ideality Approach TRIZ Methodology • The ideal system performs a required function without TRIZ concepts actually existing Contradiction Resources • The function is often performed using existing resources Ideal final result Patterns of evolution • ALL systems evolve in this direction over time by resolving Innovative Principles contradictions Contradiction Matrix • Defining Ideality breaks psychological inertia References AK Dhamija, DIPR, DRDO TRIZ, An Introduction 32/57
