Part 1. Design & Material Foundation (DFM)

Connecting point A to B is simple. Making it survive the real world is engineering. This chapter breaks down the foundation needed to turn a concept into a reliable product.

We cover the critical pillars of a robust design:

• Environmental Requirements: Defining voltage, current, and exposure limits upfront so the harness lasts years, not just days.
• Documentation: Structuring BOMs and drawings to eliminate production ambiguity.
• Component Selection: Navigating trade-offs in conductors, insulation, and connector families.
• Design for Assembly (DFA): Ensuring your CAD models are actually buildable on the factory floor.

Read on to stop guessing and start designing harnesses that last.
