To enhance the lifetime of mechanical system, parametric Accelerated Life Testing (ALT) as new systematic reliability method suggests evaluating the design of mechanical systems subjected to repeated stresses, based on failure mechanism and design. This newly developed parametric ALT helps an engineer uncover the missing design parameters (or design flaws) of the mechanical system having an effect on reliability during the product developing process. As a result, companies can circumvent product recalls due to the design flaws from the marketplace. As an experiment instance, the redesign of hinge kit system (HKS) in a domestic refrigerator was investigated.
