ABSTRACT
Success Every Time always involves a number of error-proofing devices that monitor the work, but the design of parts also plays a big role in helping operators succeed. When selecting and positioning, operators need to be able to know which is the right part and which way that part should be oriented. These key identifying features are extremely valuable for the entire processing at that workstation because the characteristics serve as reference points that battery replacement operator tooling operators can look for. In product design, the entire effort is tremendously simplified when parts have features that are easily detectable. The design of each unique characteristic needs to use identifying holes with different sizes, shapes, and locations placed in a flat area of the part. Wherever possible, also use two holes of different sizes and place them in a nonsymmetric pattern. Tabs on parts are extremely easy to sense by interference-type devices like pins, switches, and bars.
