  • Dizer que é o acronimo em russo de Theory of Inventive Problem Solving
  • Referir que o autor começou poranalizar 40 000 patentes e que actualmente foram analisadas 2,5 milhoes
  • ideality is one of the basic premises of the TRIZ methodology, and is the Refusing the idea that innovation is a prerogative of a higherintellect or the result of a random process, Altshuller started hisresearchwith the following assumption: there are some universalprinciples to innovate and to solve all the problems.driving force behind everything it tries to achieve.
  • N – artigo do design acelaration
  • When a new problem solving is faced, methods like brain-storming, trials and errors randomly explore the solution space,resulting in an important resolution time. TRIZ avoids thisrandom exploration with a convergent process that delimitatesthe research space. This process is included in TRIZ tools,and channels the efforts to an ideal solution. This time reduc-tion for the research of solution is interesting to acceleratedesign. The principle of problem resolution is illustrated inFig. 3:• Modelisation of the real initial problem in a generic problem(TRIZ tools are dedicated to this step).• Use of some TRIZ resolution tools to give a generic solutionto the generic problem (proposition of research directions forthe solution).• Transformation of the theoretical generic solution to a realsolution adapted to the real problem
  • TRIZ uses the world’s knowledgeBrainstorming and other techniques randomly help unlock that knowledgeTRIZ is systematic and repeatable Using TRIZ will not only uncover all the solutions you would have found anyway, but many more, and will ensure that no solutions are missed.  TRIZ is based on proven successful patentsThis way there is less risk involved in using an existing technology or technique in a new field than developing your own solution.You can build your own toolkit from the TRIZ toolsDuring problem solving you don’t have to use all the tools, you don’t have to bend your way of thinking and working around an inflexible toolkit.It’s quickAfter becoming familiar with the tools, you will start using them automatically and problem solving will become quicker and more effective. It can be used in groupsHaving one or two TRIZ trained people in a large group can facilitate brainstorming sessions, because they can focus the group’s attention on a few key areasIt’s not just for engineersThe principles of TRIZ apply to any problems, or situations that need more innovation and creativity, and have been used to great success to solve management problems.  It makes everybody creativeTRIZ helps naturally creative people come up with more ideas, but it works even more dramatically on people who don't regard themselves as naturally creative.
  • Chromatographic separations are unit operation techniques tocontinuously separate a multi component mixture. This technique has recently received a new interest from researcherbecause of its new applications in areas such as: biotechnology, pharmaceutical, fine chemistry ...One of the possible technological starting points of this unitseparation is the true moving bed (TMB), for which a simplifiedversion is illustrated in Fig. For the TMB separation technique,the component mixture is sent in a column where the liquid andsolid phases flow in counter current directions.The main disadvantage of this technique is theflow of the solid phase, which is a complex task.
  • N -design acellaration
  • N -design acellaration
  • With this possibility, a solution is proposed and has to beimplemented and tested before to be retained in the case base.
  • Since its emergence in the West, the method has begun to be integrated with a number of established and emerging problem definition and problem solving tools and strategies. Most notable among these are illustrated in FigureA combined systematic innovation and creativity methodology featuring TRIZ and other tools needs to be constructed on the basis of deployable benefit rather than collection of features. In other words, a combined methodology needs to be arranged on the basis that users arrive at the method with a certain type of problem to solve rather than with a pre-determined knowledge that they wish to use a certain problem definition or problem solving tool.

  • 1. Product Engineering TRIZ Theory of Inventive Problem Solving Grup 6: Carlos Teixeira Daniel Domingues José Oliveira Tiago SoaresDEQ /MIEQ November 2011
  • 2. HistoryProduct Engineering TRIZ Author: Genrich Altshuller (1926-1998), a russian inventor and naval officer. He was sent to the Siberian Gulag camp by Stalin for “thinking too much” and he was released after Stalin’s death.[1] When: 1946 (after World War II and during Cold War) Where: Former U.S.S.R. [1] www.en.wikipedia.org/wiki/TRIZNovember 2011 2
  • 3. What is TRIZ?Product Engineering TRIZ TRIZ is a problem solving toolkit derived from the study of patterns of invention in the global patent literature that can be used to rapidly generate plausible concepts that solve problems in technical and non-technical domains. [1] [2] [2] http://www.triz.co.uk/pwpcontrol.php?pwpID=165November 2011 3
  • 4. What is TRIZ?Product Engineering TRIZNovember 2011 4
  • 5. What is TRIZ?Product Engineering TRIZ 2. An inventive solution involves wholly or partially eliminating a contradiction. Through this work he discovered that inventive solutions centred on eliminating contradictions. Where contradictions are performance trade-offs. Examples of technical contradictions: strength vs. weight, speed vs. efficiency, etc. Technical contradictions are solved with the contradiction matrix.November 2011 5
  • 6. What is TRIZ?Product Engineering TRIZ The matrix tells you among the 40 principles which ones have been used most frequently to solve a problem that involves a particular technical contradiction. [4]November 2011 6
  • 7. What is TRIZ?Product Engineering TRIZ 3. The inventive process can be structured. [4] As knowledge grows in any particular field the development of the knowledge base can be viewed as going through three stages. [4] Robles, G. C., Negny, S., & Le Lann, J. (2008).

  • 8. Why use TRIZ?Product Engineering TRIZ • TRIZ uses the world’s knowledge; • TRIZ is systematic and repeatable; • TRIZ is based on proven successful patents; • You can build your own toolkit from the TRIZ tools; • It’s quick; • It can be used in groups; • It’s not just for engineers; • It makes everybody creative.[2] [2]: http://www.triz.co.ukNovember 2011 8
  • 9. TRIZ ToolsProduct Engineering TRIZ 1. Thinking in Time and Space This powerful tool works on all problem types of both technical and management nature. An example is the 9 boxes tool also known as 9 windows. The 9 boxes solution map is used when we’re sorting possible places to solve the selected problem. We use 9 boxes to set the system context, define its environment (super-system) and all the details (subsystems).[2] Table 1: Example of the 9 boxes tool.[5] Past Present Future Before ‘writing’ begins Person writing After writing has finished Super pen display in shop, user, paper desk, chair, light, storage location, wear effects System user preparing to write environment of environment System assemble pack/deliver, store, pen being used to write storing effect refilling wear the pen prepare factors, disposal Subsystem manufacture of individual component parts, ink flowing re-usability, recyclability of components through nib component parts [2]: http://www.triz.co.uk; [5]: http://www.innovation-triz.comNovember 2011 9
  • 10. TRIZ ToolsProduct Engineering TRIZ 2. Eight Trends of Technical Evolution The Trends of Technical Evolution show us how to predict new markets and new products, they map the general directions of system development TRIZ Trends help you: • Predict future technologies, new products and improvement of current systems • Define what you want – Ideality • Understand where you are - using S-Curves and seeing the next steps and future possibilities using simple patterns of the 8 TRIZ trends • See the most promising directions of your products and those of your competitors • Choose / evaluate the most promising ideas being developed and help you develop those products [2]: http://www.triz.co.ukNovember 2011 10
  • 11. TRIZ ToolsProduct Engineering TRIZ 3. TRIZ Tools for Uncovering and Solving Contradictions • The concept of contradiction is central to the TRIZ tool-kit, this gives immediate confidence in finding successful and powerful solutions. • Once we understand the conflict in our requirements we can use TRIZ processes for uncovering contradictions and find what tools we need to solve them. • Understanding all the benefits we want, getting those in the right order of priority, and seeing where these benefits conflict is the first stage in solving contradictions. This needs structure and practice for successful problem solving.[2] [2]: http://www.triz.co.ukNovember 2011 11
  • 12. TRIZ ToolsProduct Engineering TRIZ 4. Using the 40 Inventive Principles Familiarity with all 40 Principles is essential for future effective problem solving. The 40 Principles are accessed for problem solutions by defining Physical and Technical Contradictions, using: • The Separation principles to solve Physical Contradictions (you have opposite requirements for the same thing e.g. I want an umbrella big enough to protect me from the rain, but small to carry around). • The TRIZ Contradiction Matrix to solve Technical Contradictions (something improves but something different gets worse e.g. as I make something stronger, it gets heavier.[2] [2]: http://www.triz.co.ukNovember 2011 12

  • 14. TRIZ ToolsProduct Engineering TRIZ 5. Standard Solutions for Problem Solving Standard Solutions are general lists of all the ways to solve problems recorded by science and technology, particularly in patents. We use the Standard Solutions once we have identified the problem type – such as if we have something harmful. We can then step through all the ways to stop harm... • Prevent that harm from happening at all, • Transforming it so it is no longer harmful (perhaps even useful), • Block, or prevent the harm so it no longer causes a problem.[2] [2]: http://www.triz.co.ukNovember 2011 14
  • 15. TRIZ ToolsProduct Engineering TRIZ 6. Smart management of resources to overcome constraints Identification of available resources around any problem is essential for finding good, cost effective, environmentally friendly solutions. Unlike any other problem solving technique the TRIZ definition of a resource is all- encompassing and focuses even on apparently negative or harmful resources. Thinking about symmetry, smell, colour or surface finish as resources rather than just things that exist in the system helps you learn how to identify, transform and then use all the resources to focus on cost reduction and produce elegant, clever solutions.[2] [2]: http://www.triz.co.ukNovember 2011 15
  • 16. TRIZ ToolsProduct Engineering TRIZ 7. Understanding Our Requirements  The purpose, the main function we are seeking  All functionality / benefits • Everything we want (must haves / nice to haves) • Everything we don’t want Where & when we want our functionality. Identify conflicts in Time and Space  Ideal Outcome  Everyone’s Ideal Outcome[2] [2]: http://www.triz.co.ukNovember 2011 16
  • 17. TRIZ ToolsProduct Engineering TRIZ 8. System Modelling and Analysis - Function Analysis The TRIZ describes the system containing the problems in all its detail by listing all the components and all their interactions. TRIZ Function Analysis is different from other forms in that it includes all the negative, ineffective and excessive interactions in the system. All interactions are expressed as Subject-action-Object and it is important to use simple, clear language in order to be able to structure the problem correctly. TRIZ Function Analysis is powerful and links with other popular problem solving toolkits like Value Engineering, Six Sigma and Lean Sigma all of which have their roots in the middle of the last century.[2] [2]: http://www.triz.co.ukNovember 2011 17
  • 18. TRIZ ToolsProduct Engineering TRIZ 8. System Modelling and Analysis - Function Analysis Trimming Once the problems have been identified from the Function Analysis diagram we try to simplify the system using the Trimming Rules. Often this step will eliminate problems but it will also reduce the cost of the system and increase its ideality. Solution map After trimming we select one of the remaining problems to solve and identify where we can solve it (in time and space). The range of possibilities constitutes your solution map, and you choose which type of solution to try, according to what constraints you have.[2] [2]: http://www.triz.co.ukNovember 2011 18
  • 19. TRIZ ToolsProduct Engineering TRIZ 9. Using the world’s knowledge / Accessing the Patent database Knowing out how to access and use the world’s patent databases is also an important tool. Patents are a free resource available to everyone Understanding how to match what’s out there with what you are looking for and find relevant knowledge quickly and efficiently.[2] [2]: http://www.triz.co.ukNovember 2011 19
  • 20. TRIZ ToolsProduct Engineering TRIZ 10. Getting to Solutions and Minimising Risks  Understanding context and environment Seeing the whole picture is essential for good problem solving. TRIZ offers simple and quick routes to getting the context and environment understood.  Creativity Tools for breaking psychological inertia These TRIZ methods complement most normal company problem solving tools. They include Size- Time-Cost, Smart Little People and Thinking in Time and Space. They are simple to use in directed brainstorming and effective in producing creative breakthroughs.  Resolving conflicts in time and space It is necessary to think about all stages, knowing how to design everything in the system for optimum use and knowing what functionality do we need and how do they vary in time.[2] [2]: http://www.triz.co.ukNovember 2011 20
  • 21. TRIZ ToolsProduct Engineering TRIZ For more complex problems, where the ten tools of TRIZ alone are not sufficient we should use ARIZ (algorithm of inventive problems solving), a list of about 85 step-by-step procedures to solve complicated invention problems. There are various softwares based on ARIZ. [6] [6] http://www.mazur.net/triz/November 2011 21
  • 22. ExampleProduct Engineering TRIZ - Component mixture is sent in a columm. - Liquid and solid phases flow in counter current directions. - Disadvantage: Flow of the solid phase. (Complex task) True Moving Bed [4]November 2011 22
  • 23. ExampleProduct Engineering TRIZ 1st Step - Identify and formulate the drawback by the way of a technical contradiction. Contradiction: “eliminate the solid flow without reduce the separation effectiveness and increase the operating cost” 2nd Step – Identification of the two parameters (among 39) in conflict. Improved parameter: the flow of the solid phase implies a difficulty of use, consequently the parameter 33, ‘Convenience of use’ is chosen. Damaged parameter: it is the parameter 19, ‘Energy spent by a moving object’.November 2011 23
  • 24. ExampleProduct Engineering TRIZ - Crossing line 33 with column 19, isolates a matrix cell with the following principles: - 1 “Segmentation” - 13 “Inversion” - 24 “Intermediary”November 2011 24

  • 27. ExampleProduct Engineering TRIZ - The TMB is composed of one column; the application of principle 1 implies the division of the column in different zones delimited by the inlets and outlets. - The goal of the future solution is to eliminate the solid circulation, in this way the application of one of the sub principles of 13 imposes to fix the solid phase. True Moving Bed [4]November 2011 27
  • 28. ExampleProduct Engineering TRIZ Solution: The proposed solution consists in the simulation of liquid and solid counter flows by permutations (rotation) of inlets and outlets (toward the liquid flow direction). This improvement of the TMB arises in the Simulated Moving Bed (SMB), illustrated in the Fig. Simulated Moving Bed [4]November 2011 28
  • 29. TRIZ and other MethodologiesProduct Engineering TRIZ While undoubtedly powerful, TRIZ is not yet comprehensive enough to tackle all types of problems. [n] [8] Mann, D. (2000). The Four Pillars of TRIZ. Systematic Innovation.November 2011 29
  • 30. ConclusionsProduct Engineering TRIZ - TRIZ is not a miracle theory that gives in all cases innovative ideas. Its goal is to direct the solution research to a good direction thanks to analogies between technical domains. - Altshuller had built TRIZ tools with a scientific analyze of the whole technical domains, eliminating the barriers between these different domains. - Using TRIZ, you can beneficiate of solutions or ways of solution that had proved their effectiveness and consequently accelerate the design and also propose more innovative solutions.November 2011 30
