  22. 22. Apply solution principles to situationPrinciple 1. SegmentationDivide an object into independent parts. TRIZ general • Replace mainframe computer by personal computers. solution • Replace a large truck by a truck and trailer. • Use a work breakdown structure for a large project. 3Make an object easy to disassemble. • Modular furniture • Quick disconnect joints in plumbing Your specific solutionIncrease the degree of fragmentation or segmentation. • Replace solid shades with Venetian blinds. • Use powdered welding metal instead of foil or rod to get better penetration of the joint.22 Material compiled for course 42629 – Innovation and Product Development Department of 2012 Mechanical Engineering, The Technical University of Denmark
  23. 23. Apply solution principles to situationPrinciple 35. Parameter changesChange an objects physical state (e.g. to a gas, liquid, or solid) TRIZ general • Freeze the liquid centres of filled candies, then dip in melted solution chocolate, instead of handling the messy, gooey, hot liquid. • Transport oxygen or nitrogen or petroleum gas as a liquid, instead of a gas, to reduce volume.Change the concentration or consistency. 3 • Liquid hand soap is concentrated and more viscous than bar soap at the point of use, making it easier to dispense in the correct amount and more sanitary when shared by several people. Your specificChange the degree of flexibility. solution • Use adjustable dampers to reduce the noise of parts falling into a container by restricting the motion of the walls of the container. • Vulcanize rubber to change its flexibility and durability.23 Material compiled for course 42629 – Innovation and Product Development Department of 2012 Mechanical Engineering, The Technical University of Denmark

General Creativity Methods 3 methods that help you to remove cognitive inertia and produce solutions: – SCAMPER – Smart Little People – 6 thinking hats28 Material compiled for course 42629 – Innovation and Product Development Department of 2012 Mechanical Engineering, The Technical University of Denmark
  29. 29. SCAMPER checklistSubstitute - components, materials, peopleCombine - mix, combine with other assemblies or services, integrateAdapt - alter, change function, use part of another elementModify - increase or reduce scale, change shape, modify attributes (eg colour)Put - to another useEliminate - remove elements, simplify, reduce to core functionalityReverse - turn inside out or upside down, also use of reversal 29 Material compiled for course 42629 – Innovation and Product Development Department of 2012 Mechanical Engineering, The Technical University of Denmark
