2 Dr. Sara Greenberg 2 What is systematic innovation ? A set of knowledge tools methods which can enable systematic development of innovative problem solving.

3 Dr. Sara Greenberg 3 TRIZ was founded in 1946 by a Russian engineer and scientist, Genrich S. Altshuller (Oct Sept. 24,1998) " Теория решения изобретательских задач" או בעברית: "תֵּיאוֹרִיָה רֶשֶנִיָה אִיזוֹבְּרֵטַאטֵלְסְקִיךְ זַאדַאץ"

4 Dr. Sara Greenberg 4 Genrich S. Altshuller " תאוריה היא מרשימה יותר ככל שהנחותיה פשוטות יותר, ככל שהיא מקשרת בין יותר סוגי דברים שונים וככל שתחום הישימות שלה רחב יותר " אלברט איינשטיין

6 Dr. Sara Greenberg 6 Laws of Technological Systems Evolution Evolution in stages. Evolution towards increased ideality. Non-Uniform development of system elements. Evolution towards increased dynamism and controllability. Increased complexity and then simplification. Evolution with matching and mismatching components. Evolution towards Micro-level and increased use of fields. Evolution towards decreased human involvement.

11 Dr. Sara Greenberg 11 What is a Contradiction? P P An improvement in one characteristic of a system results in the degradation of another characteristic. Traditionally addressed by compromise, sacrifice or trade-off Y X Y= -f(X) Y=C Y= f(X) No compromise! Contradiction = Barrier Prevent from Achievement of the Most Desirable Result

12 Dr. Sara Greenberg 12 Evolution in stages Horns Trumpets Development of hearing aids Carbon aids Transistor Aids Digital Aids

13 Dr. Sara Greenberg 13 Evolution Towards Increased Ideality The main driving force for system evolution is increasing main system useful functions by elevating value and decreasing the harmful effects: Σ Useful Functions ` Σ Costs + Σ Harm. Functions Value = Ideality = Σ Functionality Σ Costs + Σ Harm

35 Dr. Sara Greenberg 35 Technical contradictions Step 1. Create list of parameters of the given system. Truck: Speed, Stability, Fuel consumption, Air drag friction, Weight of cargo, Power of engine, Safety Step 2. Select your favorite parameter and change its value. Truck: Speed -> increase Step 3. Analyze interactions between changed favorite parameter and other parameters of the list. Select conflicting pairs. Each conflicting pair means Technical Contradiction (TC) Speed Stability => conflict – TC Speed Fuel consumption => conflict – TC Speed Air drag friction => conflict – TC Speed Weight of cargo => not a conflict Speed Power of engine => conflict – TC Speed Safety => conflict – TC

36 Dr. Sara Greenberg 36 Problem solving example How to miniaturize the size of the printer? Restriction of reduction in the printer size is the standard width of the most widespread А4 paper which makes 210 mm. Contradiction: Contradiction: The printer should be the size of an А4 paper dimensions and should be less then the dimensions of an A4 paper in order to be portable. The contradiction was resolved by separation in space by using a geometrical effect. The sheet of a paper can be rolled up in a tube using less space.

37 Dr. Sara Greenberg 37 Portable Printer Solution The printer head in formed in a circle. Printer-ring stretches out the sheet of a paper roll up in a tube. The new printer is almost three times less, than its portable competitors working under the old circuit.

46 Dr. Sara Greenberg 46 Engineering Contradictions and Altshullers Matrix Description of the Inventive Principles NumberNameDescription of Inventive Principles 2Taking out Separate an interfering part or property from an object, or single out the only necessary part (or property) of an object 17 Another dimension To move an object in two- or three-dimensional space Use a multi-story arrangement of objects instead of a single-story arrangement Tilt or re-orient the object, lay it on its side Use 'another side' of a given area 29 Pneumatics and hydraulics Use gas and liquid parts of an object instead of solid parts (e.g. inflatable, filled with liquids, air cushion, hydrostatic, hydro-reactive) 4Asymmetry Change the shape of an object from symmetrical to asymmetrical If an object is asymmetrical, increase its degree of asymmetry AC EC sEC IFR Matrix S

47 Dr. Sara Greenberg 47 Engineering Contradictions and Altshullers Matrix Pneumatics and hydraulics The Exhaust gasses are released in such a way that they are a functional extension of the wing. They contribute to generating lift and do not add weight to the airplane. (from US Patent N )

48 Dr. Sara Greenberg 48 Separation Principles Solving Physical Contradictions Separation upon condition Separation in space Separation in time In Space In Demands

49 Dr. Sara Greenberg 49 Inventive principles

50 Dr. Sara Greenberg 50 Principle 3. Local quality Change an object's structure from uniform to non-uniform, change an external environment (or external influence) from uniform to non-uniform. Make each part of an object work in the conditions that are most suitable for its operation. Make each part of an object fulfill a different and useful function. Example: Non-uniform winding for uniform heating An infrared lamp heats a semiconductor wafer. The wafer edge cools more quickly making the temperature higher in the center. Can a uniform heating be achieved? The heater spiral is wound with more windings at its edges. This gives more heat at the edges than in the center, provides a uniform temperature over the entire surface of the wafer
