Name: th – 45 pts 1. Calculate the assembly time assuming: 1) dimensions are mm, 2) springs tangle and are flexible (but not force fitted), 3) piston spindle is sharp and goes into a small hole, 4) everything is within 0.5m, 5) steel cover has lettering on only one side, and 6) snap fits are not force fits. Initial Design: Part α - Symmetry β - Symmetry Handling Difficulites Handling & Alignment Time (s) Insertion Difficulties Insert & Secure Time (s) Total Time (seconds) Place main block 360 X X Piston Piston Stop Spring Cover Screw (just one) Total (x2 screws) Improved Design: Part α - Symmetry β - Symmetry Handling Difficulites H & A Time (s) Insertion Difficulties I & S Time (s) Total Time (seconds) Place main block 360 X X Piston Spring Cover Total
