Creative Problem Solving TRIZ

Problem Solving Methods DMAIC – Define, Measure, Analyze, Improve, Control DFSS – Design for Six Sigma PDCA – Plan, Do, Check, Act PDSA – Plan, Do, Study, Act TQM, PR, Kaizen, Pugh, WB, . . . . TRIZ – Theory of Inventive Problem Solving

TRIZ Principles Somebody, someplace, has already solved your problem or one similar to it. Creativity means finding that solution and adapting it to the current problem. Don't accept compromises. Eliminate them.

Somebody has Solved Your Problem California Dairy Farmers needed a way to dry manure Heat became too expensive Solution – hydrophilic gas which carries water away Orange Juice Concentrate

Somebody has Solved Your Problem Pharmaceutical industry needed a way to deal with excess foam from a pharmaceutical process Solution came from the beer industry Paint manufacturers needed a way to deal with sludge accumulation in equipment Solution came from nuclear waste disposal industry

Traditional Tradeoffs Technical Contradictions Stronger at cost of additional weight Greater bandwidth requires more power Faster airbag deployment requires greater force Physical Contradictions Coffee hot enough to enjoy but not so hot as to burn Software powerful features but easy to use Surveillance quick to target but slow to collect data

TRIZ Tries to eliminate problems rather than accept compromise Airbag material that can’t grab skin as it is deployed Car supersystem to avoid crashes Social system that prevents small persons from front seat Match book problem – dissolving Compromise when necessary

TRIZ Dissolution Technical Constraints Technical contradictions solved through 40 problem solving principles Physical contradictions solved through 4 basic principles to look at supersystems, subsystems, separation of time, space, etc.

Self-heating Beverage Container Contradictions Fast heating can cause steam pressure to rupture capsule Thin material allows heat transfer but isn’t strong enough Multiple thin layers strong enough but too expensive Metal top will allow traditional pop top but can burn lips

Self-heating Beverage Container Principle 1 – segmentation, instead of blow molding container, satisfy layer requirement through die stamping operation
