Emphasize asymmetry if symmetry not possible/helpful 2. Guidelines for eliminating overlapping and tangling. 1. Eliminate protrusion 2. Close coil spring ends 3. Provide thicker contact surfaces to avoid shingling 4. Reduce opening size in snap rings, etc. 5. Increase angle s on elements that might overlap 6. Use gravity to help 7. Use ribs to stop nesting 3. Guidelines for using asymmetry. 1. Exaggerate small features of asymmetric geometry 2. Deliberately add asymmetric features 3. Remove material to produce asymmetric external features 4. True False. Symmetry about the insertion axis is the best. T_X_ F Asymmetry is important as an internal feature T F_X_ Open coil springs are not difficult to feed. T F_X_ Orientation is facilitated by symmetry.
