Design-in of reliability through axiomatic design

To completely meet the requirements of reliability design in the product designing, an axiom-based designing-in reliability approach was proposed. In light of the axiomatic design principles, products were designed preliminarily to establish their functional requirements, so that according to these the preservation requirements were augmented (the functions preserving requirements constitute a functional requirement preserving domain that is included in functional domain), which derived the parameterized solution for reliability design systematically. Subsequently, the design parameters were augmented and optimized to achieve the functions preserving requirements. Mapping model of the augmented functional domain, the physical domain was established. And a solutions evaluation approach based on independence axiom was proposed. Being exemplified by the design of a temperature sensor, the present study demonstrates that all approaches are feasible, efficient, and could be applied in real engineering scenarios.
