Design-in of reliability through axiomatic design

In this paper, to completely meet the requirements of reliability design in the product designing, an axiom-based reliability design approach is proposed. In light of the axiomatic design principles, products are designed preliminarily to establish their functional requirements, so that according to these, functions preserving requirements are augmented, which constitute a functional requirement preserving domain that is included in functional domain, and derives the parameterized solution for reliability design systematically. Subsequently, the design parameters are augmented and optimized to achieve the functions preserving requirements. Mapping model of the augmented functional domain and the physical domain is established. And a solutions evaluation approach based on independence axiom is proposed. Ultimately, via identifying the potential failure modes from the perspective of the disappearance or reduction of functions preserving capability, a control process is elaborated to mitigate the failure modes based on independence axiom and logic decision in order to satisfy the reliability requirements. Taking the design of a temperature sensor as an example, the present study demonstrates that all approaches are feasible, efficient, and can be applied in real engineering scenarios.
