Reducing Component Count andd Assembly Steps

One of thee primary goals of DFA is to consolidate functions into a single part. Internal factures like molded-in snaple-fits, living hinges, and self-aligning posts can revete entire fastener assemblies (śruby, washers, orzechy). For example, instead of designing a housing that exempls a separate metal insert and screw to hold a incirít board, an engineer can model an internal plastic boss with a slot and an interference nib. This transforms a twostep assemble (plass incit, drive screv) a single (intl) a single pressf.

Enhancing Part Alignment and Self- Locating Geometric

Internal factures such as datum targes, pilot holes, and register pins are essential for controling how parts come together.
