Abstract

In a previous IRSST study in the Electrical Products Fabrication sector, ergonomists identified several problems related to wire-stripping tools used very repetitively. Needs analysis clearly demonstrated the necessity of developing a new tool, and a tool which satisfies the needs and expectations of users, and meets the specifications of users and ergonomists was therefore developed, using a method derived from simultaneous engineering.

The first prototype confirmed the functional validity of the design: preliminary factory trials demonstrated that the new wire-stripper significantly reduced the effort required to strip wire and cut wire and insulation, despite its light weight. However, certain components proved insufficiently robust for industrial use, and a second prototype which was comfortable, robust and adaptable was produced. This development stage was performed primarily by the Centre de recherche industrielle du Québec (Quebec industrial research centre), using data from preliminary trials and comments from users and ergonomists. A limited number of tools will be produced to meet companies’ needs.
