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

Product Oval and complex shaped O-rings Coated glass or paper Eccentric drive Spectacles Human-shaped seating, etc Process Introduce a geometric feature which prevents incorrect usage/assembly of a component (e.g. earth pin on electric plug) Asymmetrical funnel allows higher flow-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. 5 Property 17 SYMMETRY Symmetry
