Design and ergonomics. Methods for integrating ergonomics at hand tool design stage.

Area of Science:

• Ergonomics
• Product Design
• Occupational Health

Background:

• Musculoskeletal disorders are increasing in industrialized nations, especially among hand tool users.
• The French National Research and Safety Institute (INRS) initiated research in 1999 to address ergonomic integration in hand tool design.
• Designing safer hand tools, like boning knives, presents specific ergonomic challenges.

Purpose of the Study:

• To explore the integration of ergonomics into the design process of hand tools.
• To specifically apply ergonomic design principles to a boning knife.
• To evaluate the effectiveness of specific design methodologies in overcoming ergonomic integration challenges.

Main Methods:

• The study involved a brief review of challenges in integrating ergonomics during the design phase.
• Three design methodological tools were employed: Functional Analysis, Quality Function Deployment, and TRIZ.
• These tools were applied to the design process of a boning knife.

Main Results:

• The application of Functional Analysis, Quality Function Deployment, and TRIZ provided a structured approach to ergonomic design.
• These methodologies demonstrated their capability in addressing the complexities of integrating ergonomics into product design.
• The study highlighted the practical utility of these tools in developing safer hand tools.

Conclusions:

• The integration of ergonomics into hand tool design can be effectively supported by structured methodologies.
• Functional Analysis, Quality Function Deployment, and TRIZ are valuable tools for overcoming design integration challenges.
• This research contributes to the development of safer and more ergonomic hand tools, potentially reducing musculoskeletal disorders.
