SYMMETRY

1. 1 1 Symmetrical system Matched asymmetry Partial asymmetry Property 17 SYMMETRY SYMMETRY 1. introduction | 2. value | 3. resources | 4. nine windows | 5. analogy | 6. patents | 7. properties | 8.conflicts | 9. product dna | 10. appendix

2. 2 Property 17 SYMMETRY Asymmetric scissors to cut Asymmetrical thermometer to fit Fingered glove to grip Angled whisk to mix Shaped coffee cup lid to hold SIMcard to fit Easy closing button to grip Asymmetric saucer to hold

3. 3 Property 17 SYMMETRY Shaped nail polish bottle to grip Indent on a stapler to join Puzzle chairs to connect Joint free brick to appear Symetrical thermomter to measure Nested kithcen knives to store

4. 4 BENEFITS of SYMMETRY improve aesthetic appearance increase user convenience Symmetry add a new function or integrate another function increase grip improve ergonomics improve manoeuvrability increase grip increase grip create a more modular or stackable component assembly have a broader operating range improve user safety change object shape make it easier to operate increase user involvement improve strength reduce control system complexity create a Lego-like component assembly

5. 5 Property 17 SYMMETRY Symmetry Product • Oval and complex shaped O-rings • Coated glass or paper • Eccentric drive • Spectacles • Human-shaped seating, etc Process • Introduce a geometric feature whichprevents incorrect usage/assemblyof a component (e.g. earth pin on electric plug) • Asymmetrical funnel allows higherflow-rate than normal funnel • Put a flat spot on a cylindrical shaft to attach a locking feature • Introduction of angled or scarfed geometry features on component edges • Cutaway on a guitar improves access to high notes • Take account of differences between left and right handed users • Spout of a jug • Car steering system compensates for camber in road • Wing design compensated for asymmetric flow produced by propeller • Use of variable control surfaces to alter lift properties of an aircraft wing • Special connectors with complex shape/pin configurations to ensure correct assembly • Introduction of several different measurement scales on a ruler Aerofoil - asymmetry generates lift.
