Appearance and structure are not sequential but parallel calibrations. The earlier the involvement of interfaces, wall thickness, assembly, and process constraints, the less rework will be needed.

Why is rework common

Common reason: appearance is "fixed" first, with structural constraints added later, leading to major changes before mold-making.

Another type focuses only on "being able to assemble," ignoring ergonomics, gaps, visual continuity, and mass production consistency.

Minimum Closed Loop for Parallel Collaboration

Synchronize Critical Dimensions, Battery/Mainboard Boundaries, Button Travel, and Waterproof Rating During the Concept Stage.

Each Design Review Includes a Structural Risk Checklist: Mold Release, Shrinkage, Assembly Tolerance, Screw Concealment, and Process Feasibility.

Youtai Intelligent's Suggestions

Replace Single-Point Approval with "Appearance-Structure Joint Review"; Synchronize Changes Across Both Deliverables Instead of Verbal Patches.

For Complex Assembled Products, Prioritize Partial Prototype Verification Of Interfaces Before Full-Scale Molding.
