DfR of the Grill Oven Relay

Abstract

Translate Article

This paper presents the application of the Design for Reliability (DfR) approach to the relay controlling the oven's grill heating element. The conventional stress-versus-strength reliability methodology is enhanced through data from connected devices and localized load measurements, enabling the derivation of a detailed load spectrum for the relay. This approach increases the accuracy of reliability predictions, eliminating the need for success-run tests typical of the test-to-pass approach.
