TOWARD DESIGN FOR SAFETY PART 2: FUNCTIONAL RE-ENGINEERING USING AXIOMATIC DESIGN AND FMEA

The design process of product development is the earliest opportunity to integrate safety into the product. The term ‘design for safety’ captures this effort to integrate the safety knowledge in the design process. In this context, this research suggests to do ‘design for safety’ through two sequential methods in two parts. In the first part a method for functional reverse engineering (FRE) driven by Axiomatic Design (AD) was proposed. The second part, discussed in this paper, proposes a functional re-engineering (FR2E) using AD and failure mode and effect analysis (FMEA) to define a system with high mechanical safety as well as reliability and robustness. This method is validated through a case study that examines a power take-off (PTO) system.
