An interesting case study that I authored on Bresslergroup's ergonomic redesign of a hand tool - the The Thomas & Betts Sta-Kon® ERG-4001 (Pressmaster-K67). It's a crimper used by electricians and other to crimp wires, a manual task that is physically demanding and repetitive.
The case study provides a background into the ergonomic issues addressed, and the Strength/Reach/Posture/Clearance framework that we used to structure our analysis and redesign efforts. The resulting tool had significant, measurable improvements in ergonomics, most notably the diminished manual force curve compared to competitor products (charted above).
