Asymmetry is the opposite. Design for symmetry Create a design that will work no matter how we install the symmetrical part. (A shim, a pin, or a piece of paper, for example.) Design for asymmetry If a part isn’t functionally symmetrical, it shouldn’t look symmetrical. The part should obviously only go in one way. 页眉 * 页眉 * 页眉 * 页眉 * 页眉 * 页眉 * 页眉 * Pins: Prevent something from being installed backwards (Symmetry issues) Templates: Anything that can be placed over a product to indicate a wrong condition such as a sheet with cutouts for each component on a PC board Can also be an assembly tool as in the wiring switch Checklists: Used where a number of steps must be performed, as in pilot’s pre-flight checklist Parts kit with shadowboxing: Used on assemblies where there is a danger of forgetting a component Limit switches: frequently used to prevent the powering up of a machine unless the workpiece is properly installed (As in a microwave oven door). Can also be used to stop operation if some characteristic is not right. Counters: Used whenever there are a large number of a similar task to be performed (Such as torquing hardware).
