Backup : TRiZ methods and tools Is it possible to learn to be an inventor? • Soviet engineer and researcher Genrich Saulovich Altshuller began to develop TRiZ theory while working in USSR patent office at the time of Stalin Description from Wikipedia, the free encyclopedia He and his colleagues reviewed over 200,000 patent abstracts in order to find out in what way the innovation had taken place Even incarcerated under political charges, he continued his work on TRiZ while in the Gulag labor camps • Altshuller eventually developed an extensive work represents a unique contribution to the development of creativity and inventive problem-solving 40 Principles of Invention several Laws of Technical Systems Evolution, the concepts of technical and physical contradictions that creative inventions resolve the concept of Ideality of a system 47 and numerous other theoretical and practical approaches 2007 © Pascal Sire
  48. 48. Backup : TRiZ methods and tools Is it possible to learn to be an inventor (cont’d) • While Altshuller was still alive, he repeatedly stated, • "TRiZ, as a science, must belong to all" Description from Wikipedia, the free encyclopedia TRiZ should have no limitations to whom and where it can be used. The different schools for TRiZ and individual practitioners have continued to improve and add to the methodology. • The tools developed under Altshuller's leadership were 40 Principles 1946-1971, ARiZ 1959-1985, Separation Principles 1946-1985, Substance-Field Analysis (Su-Field Analysis) 1973-1981, Standard Solutions 1977-1985, Natural Effects (Scientific Effects) 1970-1980, Patterns of Evolution 1975-1980... 48 2007 © Pascal Sire
  49. 49. Backup : TRiZ methods and tools TRiZ – The Theory of inventive problems solving • TRiZ, (pronounced [triz]), is a Russian acronym for "Teoriya Resheniya Izobretatelskikh Zadatch" (Теория решения Description from Wikipedia, the free encyclopedia изобретательских задач), a Theory of solving inventive problems or Theory of inventive problems solving, developed by Genrich Altshuller and his colleagues since 1946. • TRiZ is a methodology, tool set, knowledge base, and model- based technology for generating innovative ideas and solutions for problem solving. TRiZ provides tools and methods for use in problem formulation, system analysis, failure analysis, and patterns of system evolution (both 'as-is' and 'could be'). • TRiZ, in contrast to techniques such as brainstorming (which is based on random idea generation), aims to create an algorithmic approach to the invention of new systems, and the refinement of old systems. 49 2007 © Pascal Sire
  50. 50. Backup : TRiZ methods and tools TRiZ – Level of Invention • Level of Invention is a relative • It should be noted that these degree of changes to the previous Levels of Invention are applied to system (or solution) in the result of solutions rather than problems requiring a system of solution. solution of inventive problem (one Description from Wikipedia, the free encyclopedia containing a contradiction). • Term was defined and • Also level of invention and the introduced by TRiZ author potential for innovation in any G.

  55. 55. Backup : TRiZ methods and tools TRiZ – Identifying a problem: no compromise! • Altshuller believed that inventive problems stem from contradictions (one of the basic TRiZ concepts) or trade-offs between two or more elements. Description from Wikipedia, the free encyclopedia • There are Technical Contradictions, such as "If we want more acceleration, we need a larger engine - but that will increase the cost of the car", that is, more of something desirable also brings more of something else undesirable, or less of something else also desirable. • He also defined so-called Physical contradictions: we may need at the same time more and less of something. For instance, we may need higher temperature in order to melt a compound more rapidly, but lower temperature in order to achieve a homogeneous mixture. • An inventive situation might involve several such contradictions. The inventor typically does not resolve a contradiction by stepping in the middle of the trade-off - for that, no special inventiveness is needed. Rather, the inventor develops some creative approach for dissolving the contradiction: for instance, inventing an engine that does produce more acceleration without increasing the cost of the engine. 55 2007 © Pascal Sire
  56. 56. Backup : TRiZ methods and tools TRiZ typologies of Contradictions © Copyright “Advanced Master in Innovative Design“ INSA Strasbourg • On a social level Problem description contains social expectations. We can find conflict between human being and technology. Desired result is expressed but answers to typical questions are absent. • On an administrative level Problem description contains expectations towards organizations and management. We are facing with a conflict between human being an technical system. The answers are only partials and belongs to the super system. • On a technical level Conflict appear within existing technical systems. The answers to typical questions are uncompleted but lies within the system. • On a physical level Problem description contains concrete physical phenomena. A conflict appear between physical properties of a specific element of the system. Answers to typical questions are formulated at the level of sub-systems. 56 2007 © Pascal Sire

  60. 60. Backup : TRiZ methods and tools TRiZ – Substance-field analysis © Copyright “Advanced Master in Innovative Design“ INSA Strasbourg • One more technique that is frequently used by inventors involves the analysis of substances, fields and other resources that are currently not being used and that can be found within the system or nearby. • Note that TRiZ uses non-standard definition for substances and fields. Altshuller developed methods to analyse resources; several of his invention principles involve the use of different substances and fields that help resolve contradictions and increase ideality of a technical system. • For instance, video text systems utilized television signals to transfer data, by taking advantage of the small time segments between TV frames in the signals. 60 2007 © Pascal Sire

Backup : TRiZ methods and tools Method for overcoming mental inertia (Multi-screen) • This method allows you to represent a developed system mentally with application of at least 9 screens. • System itself, super system and subsystem are each represented in the past, present and future. • This approach leads to developing new concepts of Definition from triz.org solution and overcoming failures. • With the help of this method, it is possible to consider a problem from diversified and unexpected points of view. 61 2007 © Pascal Sire

  64. 64. Backup : TRiZ methods and tools ARiZ – Algorithm of Inventive Problems Solving • ARiZ (russ. acronym of Алгоритм решения изобретательских задач) - Algorithm of Inventive Problems Solving is problem solving technique in form of list of (about 85) step-by-step procedures that incrementally evolves a complex problem to a Description from Wikipedia, the free encyclopedia point where it is simple to solve. Cf. Genrich Altshuller. • Complex problems cannot be solved in just two steps. For those problems which are so complex, that they cannot be solved with any other tools, TRiZ includes the algorithm to follow which will facilitate the problem-solving process. ARiZ is not an equation, but rather a multi-step process asking you a series of questions that integrates different pieces of TRiZ. • ARiZ is a very "solution neutral" (i.e. neutral to industry where problem emerged) process: i.e., it takes preconceived solutions out of the problem statement. It starts you at a position that assumes the nature of your problem is unknown. ARiZ reacquaints you with your problem by allowing you to see your problem with a fresh pair of eyes. 64 2007 © Pascal Sire
