Abstract

Many commercial hand tools have been designed without ergonomic principles in mind which can result in the occurrence of upper extremity trauma. In this study, therefore, a clamping hand tool, Quick-Grip® bar clamp, was selected, ergonomically evaluated, a new version of the clamp focused on the handle was developed, and the original and ergonomically designed versions were compared using survey questionnaire. Design processes of the development of a new version were evaluation of the original clamp regarding ergonomic guidelines and anthropometric data, an idea sketch, prototype development, drafts and rendering of new design, development of final model, and objective and subjective comparisons to the original handle. Eleven male and eleven female students participated in the subjective testing portion which entailed questions after finishing simulated work. The results revealed that subjects were satisfied with the new version that was comfortable to hold and use in any position due to the rounded shape, the handle dimensions were appropriate, and no subjects reported pain in the hand. This study shows that application of ergonomics principles to the design of hand tools could increase usability and value of products and should be considered by manufacturers and designers.
