Abstract

Perforator is widely used to punch hole on papers. However, there are problems with the existing perforator corresponding to its size and weight. Size of the existing perforator is quite large which leads to setback to store it in the pencil case. Furthermore, the weight of existing perforator is quite substantial and inconvenience to carry it everywhere. To solve the issues, a new perforator which is lightweight and appropriate size was designed and fabricated. Information from users and anthropometry of palm and fingers were determined through a questionnaire survey and ergonomics assessment respectively. The users’ requirements were analyzed using Quality Function Deployment (QFD) and a prototype of redesigned perforator was fabricated based on the essential users’ requirement. Redesigned perforator was evaluated through a questionnaire survey and statistical analysis between existing perforator and redesigned perforator. The findings of this study show that “lightweight”, “easy to hold”, “safe to environment”, “appropriate size” and “multipurpose” were the most essential features in the redesigned perforator. Evaluation of the redesigned perforator proved that it was successfully accommodated users’ requirement. As a conclusion, integration of ergonomics approach and QFD was proved to be an appropriate and scientific tool to redesign the perforator.
