Design and Ergonomics : Methods for Integrating Ergonomics at Hand Tool Design Stage

Marsot J., Claudon L.

International Journal of Occupational Safety and Ergonomics

2004

Vol. 10, No. 1

13--23

As a marked increase in the number of musculoskeletal disorders was noted in many industrialized countries and more specifically in companies that require the use of hand tools, the French National Research and Safety Institute (INRS) launched in 1999 a research project on the topic of integrating ergonomics into hand tool design, and more particularly to a design of a boning knife. After a brief recall of the difficulties of integrating ergonomics at the design stage, the present paper shows how 3 design methodological tools. Functional Analysis, Quality Function Deployment and TRIZ.have been applied to the design of a boning knife. Implementation of these tools enabled us to demonstrate the extent to which they are capable of responding to the difficulties of integrating ergonomics into product design.

Integration of Ergonomics Into Hand Tool Design: Principle and Presentation of an Example

Aptel M., Claudon L., Marsot J.

International Journal of Occupational Safety and Ergonomics

2002

Vol. 8, No. 1

107--115

The development of ergonomic tools responds to health protection needs on the part of workers, especially the work related musculoskeletal disorders of the upper limbs and to the development of ergonomic tools to take into account the needs of the factories. Only an ergonomic design process can enable tool manufacturers to meet these requirements. Three factors are involved: integration of ergonomics into the design process, definition of the different ergonomic stages involved, and finally knowledge of the different factors involved in hand tool design. This document examines these 3 elements in more detail and presents briefly a project of research whose main purpose is to integrate ergonomic criteria into a design process.
