3 Genrich Saulovich Altshuller October 15, 1926 to September 24, 1998 The History of TRIZ TRIZ is the Russian acronym for Theory of Inventive Problem Solving. This theory was first developed in 1946 by Genrich Altshuller. At the time, Altshuller was a patent agent in the Soviet Navy. He wrote a letter to Stalin telling him he had found a way to make the Russian people more innovative. As a reward for his patriotism, Stalin sent Altshuller to the Gulag. He continued his research into TRIZ for over 40 years. In 1992, the leading TRIZ scientists trained by Altshuller emigrated to the United States to establish Ideation International. 3

10 Synergistic Benefits of Value Management and I-TRIZ Value Management relies on various brainstorming techniques to generate problem solutions The economic value of the project depends upon identifying an innovative solution Most brainstorming techniques used are psychological in nature and plagued by psychological inertia I-TRIZ is a scientifically based problem solving methodology I-TRIZ is driven by a knowledge base of over 3 million world wide patents and other technical resources I-TRIZ can generate a near exhaustive set of potential solutions The combination of Value Management with I-TRIZ offers an opportunity to identify higher value solutions more quickly than either technique alone 10

11 Example Problem: Staple Remover Objective: Improve the utility and reduce the cost of manufacture without reducing quality 11

12 Example: Staple remover Source: J. J. Kaufman Associates, Inc., The Principles and Applications of FAST 12

13 Staple Remover Basic FAST Diagram Source: J. J. Kaufman Associates, Inc., The Principles and Applications of FAST 13

14 FAST Model as a Problem Formulator Diagram Go to Ideation Innovation WorkBench Software 14

15 Transition to the Next Generation Building Bi- and Poly- Systems The opposite of a staple remover is a stapler. Can we combine a staple remover with a stapler? 15

16 Transitioning to the Next Generation (Hybridization) Combination Staple Remover / Stapler 16

17 Universal Operators Inversion The fingers on the staple remover close. Can we make a staple remover where the fingers open? Yes. 17

18 Universal Operators - Inversion Reverse Action Staple Remover 18

19 Readily Available Substance Resources The stapled paper lies on a table or desk. This surface is a resource. Can we use this resource to eliminate having fingers that close? Yes, we can use a knife shaped object to wedge between the table and the staple. 19

20 Use of Resources Sliding Knife Staple Remover 20

21 Conclusion 1 FAST models are easy to convert into I-TRIZ Problem Formulation diagrams. No specific rules are necessary. The I-TRIZ Problem Formulator effectively supports brainstorming sessions with Directions for Innovation and Refined Formulations 21

22 Adding Design Elements to the FAST Model 22

23 Extending the FAST Model The purpose of the FAST Diagram is to relate How, Why and When functions happen in a system The I-TRIZ Problem Formulator relates the useful and harmful effects of functions as well as objects, actions, parameters, and conditions. Therefore, the results of the I-TRIZ system will be improved by adding objects, actions, parameters, and conditions which are not normally included in a FAST diagram 23

24 Design Elements: Small rivets (upper) Finger grip (upper) Large finger Spring Large rivet Small finger Finger grip (lower) Small rivets (lower) 24

25 Problem Formulator with FAST Diagram Plus Design Elements Go to Ideation Innovation WorkBench Software 25

26 Idealization Consolidation of Subsystems Can the lower small rivet s function be combined with any other element in the staple remover? Yes, the rivets can be molded into the finger grips. 26

27 Increasing Idealization Elimination of Small Rivets Metal rivet replaced with plastic rivet molded into Finger Grip Metal rivet replaced with plastic latch molded into Finger Grip and fastened through slot in side of Finger 27

28 Conclusion II Adding physical elements to the Problem Formulator increases the opportunities for product improvement Some opportunities for cost reduction are identified Ideality can be increased (total ideality would perform the function without any physical manifestation of the system) 28

29 Adding Harmful Functions to the FAST Diagram 29

30 Why Do We Need Harmful Functions on the Diagram? Harmful functions counteract useful functions thus reducing ideality Harmful functions can be neutralized by secondary useful functions thus increasing system complexity Harmful functions on the diagram help to reveal and better understand the real and hidden problems 30

32 Focus on Harmful Performance Go to Ideation Innovation WorkBench Software 32

33 40 Innovation Principles Replacement of Mechanical System Can a magnetic field be used to prevent the staple dropping? Yes, steel fingers can be magnetized. 33

34 40 Innovation Principles Replacement of Mechanical System Can an asymmetrical design be used to prevent the staple dropping? Yes, the fingers can be made wider at the point to hold the deformed staple. 34

35 40 Innovation Principles Ideas: Fingers magnetizing for capturing removed staples 2 o Open big finger s sides for 2-3 o to hold removed staples 35

36 Focus on Cost Elements as Harmful Functions Go to Ideation Innovation WorkBench Software 36

37 Insufficient Useful Characteristic Transform the Shape Can we reduce the cost by changing the shape of the metal fingers? Yes, they can be made thinner. 37

38 Insufficient Useful Characteristic Transform the Shape If we make the fingers thinner, can we introduce a strengthening element? Yes, we can add ribs for strength. 38

39 Some cost reduction ideas Reducing excessive thickness of metal fingers Reducing metal thickness by providing ribs for rigidity 39

40 Conclusion III Addition of harmful functions permits I-TRIZ to focus on both elements of Ideality (Useful Functions and Harmful Functions) Cost elements from classical Value Management can be introduced as I-TRIZ Harmful Functions Starting with the FAST Diagram and adding the design elements and Harmful Functions offers the most robust brainstorming. Integration of Value Management with I-TRIZ provides significantly greater economic value 40
