Reliability analysis for the design of an inflator

Abstract

Product reliability is determined at its design stage and must be identified to adequately evaluate the feasibility of the current design. Reliability prediction provides the means to design verification and optimum modification. A design team must detect any potential reliability problems before the completion of the product design. This paper presents an approach to include the use of a reliability block diagram for reliability prediction, a fault tree analysis for detecting possible failures, and the axiomatic design procedure in the product design evaluation process. The discussion includes the reliability analysis of a passenger side airbag inflator design. The modification of the current inflator design is also discussed.

“…(2) frequency of occurrence (O), and ( 3) detectability (D) of their occurrence. [87][88][89][90] One example of where technical failure mode could occur is when an institution has an MR Safe or Conditional RT immobilization device or accessory that appears visually similar to one that is MR Unsafe, which could lead to patient injury or damage the MR equipment. Another possible technical failure mode is that an MR Conditional RT immobilization device or accessory could be used outside of the conditions that it has been tested for.…”
