snap-fit, mechanical fuse, failure indication, non-destructive evaluation, modular assembly, high-reliability design 1. Introduction Fixing tabs—cantilevered, U-shaped, or torsional springs molded into plastic or metal components—are the workhorses of modern assembly. Their simplicity belies a critical vulnerability: they fail without warning. A tab that has lost 80% of its retention force looks identical to a new tab. This latent failure mode forces conservative design (over-dimensioning) or frequent manual inspection.
