  • Before we goes into TRIZWhy innovate?What is the differences between innovation and invention?
  • Invention is difficultWhy re-invent the wheel?
  • Guidelines here refer as tools, approach, etc
  • – TRIZ Cartoon
  • Brainstorming and other techniques randomly help you unlock the knowledge in the roomBUTTRIZ helps you systematically unlock your own knowledge and unlocks the world’s knowledge.
  • During problem solving sessions, you may uncover some great solutions without using TRIZBUT 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. You will always come out of a problem solving session with several workable solutions.
  • there is less risk involved in using an existing technology or technique in a new field than developing your own custom-made solutionEveryone finds tools that they prefer, and then stick to the tools that work best for them: you don’t have to bend your way of thinking and working around an inflexible toolkit.Like any new skill you have to practice, and at first you may go slow. However, once you’ve become familiar with the tools, you will start using them automatically and problem solving will become quicker and more effective.Having one or two TRIZ trained people in a large group can facilitate incredibly effective, structured brainstorming sessions, because they can focus the group’s attention on a few key areas that they know will lead to good solutions.The 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.TRIZ 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. Everyone's creativity is improved.
  • DeBono – 6 Thinking Hats Buzan – MindMappingFunction Analysis - Functional analysis is the branch of mathematics, and specifically of analysis, concerned with the study of vector spaces and operators acting upon them.QFD - Quality function deployment (QFD) is a “method to transform user demands into design quality, to deploy the functions forming quality, and to deploy methods for achieving the design quality into subsystems and component parts, and ultimately to specific elements of the manufacturing processQuantitative / Qualitative6 Sigma - is a business management strategy originally developed by Motorola- seeks to improve the quality of process outputs by identifying and removing the causes of defects (errors) and variability in manufacturing and business processes. It uses a set of quality management methods, including statistical methods, and creates a special infrastructure of people within the organizationDFMEA - Design Failure Mode Effects Analysis (DFMEA) is the application of the Failure Mode and Effects Analysis method specifically to product design- by the Automotive Industry Action Group (AIAG).
  • Creativity – generation of new ideas or new associations between existing ideasInvention – Making a product out of an idea, Idea Realization, dream come true – GET PATENTInnovation – Transfer of creative ideas into SALEABLE goods, processes and services. IDEA + IMPLEMENTATION + CUSTOMER VALUE

  • First 5 is the most tool used
  • Class-1: Building and Destruction of S-Fields-, is dedicated to solving the problems for which it is necessary to construct or to transform s-field models. This class includes 2 subclasses and 13 Standards with specific rules for synthesis (first subclass) and destruction (second subclass) of s-fields. The selection of the necessary Standard depends on the starting conditions and restrictions, which are specified by the problem. Class-II: Development of S-Fields-, is related to solving problems through evolution of s-field models. This class contains the generalized models for improving the efficiency of the initial technical system by introducing a relatively small modification of the system. In this class, there are 23 Standards, distributed into 4 subclasses: transition to composite s-fields, improvement of s-fields, coordination of a rhythm, and complex s-fields. Class-III: Transition to Supersystem and Microlevel- is used for problem solving with the development of a solution on the level of the supersystem or subsystem. This class includes two subclasses, "Bi-systems and Poly-systems" and "Transition to a Microlevel", with 6 Standards. Class-IV: Standards for Detection and Measuring- is dedicated to solving "measuring" problems or problems that have the specific purpose of detecting something. In this class there are 5 subclasses with 17 Standards. Class-V: Standards on Application of Standards- is intended for development of the solution that will meet the demands of the ideal system. For the development of a high level invention, it is necessary to remove a conflict: the substance should be entered and should not be entered into the system. This class contains 5 subclasses with 17 Standards with rules for resolution of such conflicts.

  • Static Laws: 1. Completeness of parts of the engineering system. Every technical system consists of engine, transmission, limbs and controls. Evolution will take place to all these parts. 2. Enery Conductivity of the system- The better the transfer of energy inside the system, the better the system.3. Harmony of the parts of the system- Better harmony in timing, frequency etc. improves performance of the system.Dynamic Laws: 4. Transition from Microlevel to Macrolevel which improves miniaturization.5. Dynamicsation - that moves the evolution from a rigid structure to a flexible one.Cinematic Laws6. Moving towards increasing ideality. Every stage of evolution will move closer to the ideal system.7. Moving from complecated system to simplified system.8. Elemination of redundant stages and Transition towards the super-system. Transition from single to double to multipleMonolithic items are split into multiple components for efficiency and convenience. Single purpose products are made multi-purpose products. For example, pen with single color ink to pen with different color ink. The transition from rigid to flexible to wave technologies. According to this trend the products are moving from rigidity to flexibility. The future stages of the product will be more and more flexible. For example, fixed gates to collapsible gates, fixed tables to openable and ajustable tables etc. The transition from mechanical to thermal to electronic energy application. Machines are becoming more automated. Human operated machines are converted to petrol operated to battery operated machines. Many are converted to solar and atomic energy operated. For example, bi-cycle to motor-cycle, mechanical watch to battery operated watch, electric lights to solar lights, steam engine trains to diessel engine to electric engine etc. Transition from large to small Products are moving from large size to small size. For example, Old generation computers were large, which were replaced by small personal computers. Current age laptops and palmtops are still smaller. This shows a trend towards future computers of even smaller size. Another example, Large clocks to small wrist watches to macro clocks. Strait lines to curves Flat surfaces are made curved surfaces for convenience of use. For example, reclangulartv-remotes are made curved to fit better with the shape of human palms. Flat rests are made curved rests to give better support to the back. Manual to automatic, or moving towards decreasing human involvementProducts move towards reduced human involvements. As human time is precious products intend to work automatically without being operated by human beings. For example, thermostats in car engine fans, tv-timer to switch of tv automatically ater some time. Transition towards controllabilityProducts become more and more controllable. Better products have higher controllability. For example, electronic equipments, space shuttles.
  • The substance resources are all substances used in the analyzed system and in an external environment. The energy resources are all kinds of energies and fields such as electrical, electromagnetic, thermal fields etc. These resources are already present in the improved system or in the external environment where the system resides. The time resources include the time before the production, time gaps during production and time running of the system etc. The functional resources are the functions of the system and the resources of the system. We may be knowing only a few functions of the system, but when we discover the other functions of the system those functions can work as great resources. For example, we know the function of a pencil is to write. When we know that the pencil lead can be used as a lubricant to remove the noise in the door hinges, the lead is a good electro conductant and can be used in the touch points of a remote control etc. the same pencil gives us more resources. The information resources are data on parameters of substance, fields, change of properties or of object. They are used used in solving problems on measuring, detection and separation.The combined resources are the combination of the above prime resources. Sometimes we get new resources by a specific combination of the above resources. Sometimes we change the property of the resource (making liquid to solid and vice versa) by using temperature or other resources and produce new resources.
  • For example, if the system being analyzed is a lawnmower, the Function Statement and Analysis columns look like this: Blade cuts grass (useful) Motor turns blade (useful) Gasoline powers motor (useful) Gasoline pollutes air (harmful) Blade hits rocks (harmful) Grass & rocks dull blade (harmful) Et cetera

    26. 26. The Matrix 26
    27. 27. How to use?• Desired changes versus undesired changes• What we want versus What we don’t want• Ideal End Result versus Affected Parameters• Improve Versus Worsening Parameters• Eg: To increase speed of vehicles and at the same time increase safety – Speed versus Safety – Safety versus Speed • Parameter No. 9 Vs No. 27 • Parameter No. 27 Vs No. 9 – Result: • Principles No. 11, 35, 27, 28 • Principles No. 21, 35, 11, 28 27
    28. 28. IFR• A description of the best possible solution for the problem situation (or contradiction) regardless of the resources or constraints of the original problem• To overcome psychological inertia and reach breakthrough solutions by thinking about the solution in terms of functions, not the intervening problems or needed resources.• It focuses on functions needed, not the current process or equipment• The goal of formulating the IFR is to eliminate rework by addressing the root cause of the problem or customer need.• A basic principle of TRIZ is that systems evolve towards increased ideality, where ideality is defined as • Ideality = S Benefits / (S Costs + S Harm) – Evolution is in the direction of » Increasing benefits » Decreasing costs » Decreasing harm 28
    29. 29. IFR • 4 characteristics of IFR • Eliminates the deficiencies of the original system 1. • Preserves the advantages of the original system 2. • Does not make the system more complicated (uses free or available resources.) 3. • Does not introduce new disadvantages 4.• TRIZ Approach Current IFR Intermediate Solution Starts Here 29
    30. 30. IFR• IFR solutions is pure FUNCTION Zero Product Cost Zero Weight Zero Size/Volume Zero Quality Defects Zero Development Cost Zero Time To Market 30
    31. 31. IFR • Eg: – Self Cleaning Clothes – Self Cleaning Glass – Self Cleaning Wall Paint – Self Monitoring Car – Self-timing egg Intermediate Solution SpaceCurrentSolutionSpace IFR TIME 31
    32. 32. Inventive Standard• To solve complex industrial problem• A Structured rules for synthesis and reconstruction of technical system• Divided into 5 classes – Class-1: Building and Destruction of S-Fields – Class-II: Development of S-Fields – Class-III: Transition to Supersystem and Microlevel – Class-IV: Standards for Detection and Measuring – Class-V: Standards on Application of Standards 32
    33. 33. Inventive Standard• Steps in applying the standard 1. Define the type of problem in the beginning. 2. Build an initial s-field model of the problem. 3. Apply the Standards for development of the s-field model of a generic solution 4. Refine developed s-field model 5. Generate the specific solution conceptsExample at TRIZ Journal 33
    34. 34. Trends of Evolution (S-curves) to predict the future characteristics of the products in the process of product evolution based on the fact that all products, process or technical systems evolve over time There are certain patterns of evolution which repeats in every product or system According to TRIZ, if this trend or patterns is apply properly, then we can predict the future of the product 34
    35. 35. S-Curves• Laws governing the Trends of Evolution – Static Law – Dynamic law – Cinematic Law• Trends in Technology Evolution – Transition from single to double to multiple – The transition from rigid to flexible to wave technologies – The transition from mechanical to thermal to electronic energy application – Transition from large to small – Strait lines to curves – Manual to automatic, or moving towards decreasing human involvement – Transition towards controllability 35
    36. 36. Resources• One of TRIZ fundamental in solving problem• Evaluate the resources around us – Smell, Touch, and See – Negative or positive resources – Big or small resources – Mechanical, human, electrical, water, air, etc• Divided into – Substances – Energy – Space – Time – Functions – Information – Combine Resources 36
    37. 37. Resources• How to use? – Prioritize • First consider free of charge resource which are already there in the system • resources outside the system but easily available and at very low cost • resources available at a cost – Analyze • Formulate a list of resources • prioritize them in their order, internal and free at the top, external and paid at the bottom. • Define what kind of resources are needed for solving the problem • Evaluate and estimate each of the existing resources • Prioritize in the order of their effects/ usefulness to the given problem 37
    38. 38. Function Attribute Analysis (FAA)• to understand the elements of the system, their interactions, and the problems with those interactions• Why? Solutions change over time BUT functions remain – Functions: Move from A to B • Walk, Horse, Motorbike, Car – Functions: Cleaned clothes • Soap, Water, Detergent, etc – Functions: Remove water from tank • Break, pump, foam, boiling, etc• Defined – Process mapping – Steps in a time sequence – Relationships between system elements at each process step 38
    39. 39. FAA Main Function MUseful functions 1. Identified the componentsHarmful functionsInsufficient functions 2. Identified the functions • Main FunctionsExcessive functions • Sub-functionsMissing functions • Etc 3. Characterize functions • Useful functions • Negative functions 4. Define problem 5. Look for solutions idea 39
    40. 40. FAA • Can I eliminate this part? • Do I need the functions offered by the part?TRIMMING • Can something else in or around the system perform the functions? RULES • Can an existing part perform the function? • Can a low cost alternative perform the functions 40
    41. 41. Su-FieldWhat is S-Field Model1. An s-field consists of at least two substances ("S1" and "S2") and a field ("F")2. In an s-field model, "S1" is a product that will be processed, "S2" is a tool that processes and "F" is a field (or energy or force) used by the tool "S2" to act on the product "S1".3. The fields in a s-field can be:  Mechanical (pressure, force, gravity)  Electrical (electric field, current, electric waves)  Magnetic (magnetic fields)  Thermal (application of heat or cold)  Audible (acoustic sound, waves of all frequencies)  Chemical (chemical reactions that change a substance)  Biological (biological interactions between elements). S1 is a "product" that will be machined, processed, developed, measured, changed, etc. S2 is a "tool," an element that provides (or produces) these changes, actions or operations. Typically, only a tool can be modified and improved. F is a "field" (or energy, force) used by the tool, S2, to act upon the product, S1. Lines between elements show interaction between elements. Interactions can be useful, harmful, unregulated, poor or absent. 41
    42. 42. Space-Time Interface• Also know as 9-windows / System Operator• Take into account not just the system or problem but also the main problem or main system and/or the sub- system• Shows the trend of the solutions• Will help to find/identified problem correctly• It can be 12-windows• Start with present than move front and back (past & future) and move up and down (sub and super) 42

    44. 44. ARIZ• Russian Acronym for "Algorithm of Inventive Problem Solving".• The analytical tool of TRIZ used for defining a problem through problem defining algorithm• ARIZ (ARIZ85C) contains nine steps as below. – Restructuring of the Original Problem • Analysis of the system, which helps to define the basic function of the system and the root conflict that is worth solving. • Analysis of the resources of the system includes analysis of the zone where the selected conflict happens, periods when it happens and objects and energy that system has. • Define the Ideal Final Result and Formulate the Physical Contradiction – II. Removing the Physical Contradiction • Separate the Physical Contradiction-which includes application of one of six rules to separate conflicting requirements. • Apply the Knowledge Base: Effects, Standards, and Principles • Change or reformulate the problem – III. Analyzing the Solution • Review the Solution and Analyze the Removal of the Physical Contradiction, • Develop Maximum Usage of the Solution, • Review all the Stages in ARIZ in "Real Time" Application. 44
    45. 45. Quick Test for a good solution 45
    46. 46. Conclusion• Someone, somewhere, had solve the problem• Innovation (part of MIMOS tag) is putting the idea into saleable item• 90% of ideas are not saleable (• TRIZ is NOT a SOLUTION to a problem BUT a tool to generate better and useable idea to solve the problem.• TRIZ is not to find root cause of a problem BUT a tool to solve founded root cause of a problem 46
