The Challenge

An existing mechanical housing assembly required dimensional correction and structural reinforcement.

The original part suffered from tolerance inconsistencies, stress concentration around mounting points, and material fatigue under repeated use.

The goal was not aesthetic improvement — but functional reliability, manufacturability, and long-term durability.

Scope of Work

  • Dimensional analysis & part measurement
  • Reverse CAD reconstruction
  • Tolerance evaluation
  • Structural redesign
  • Rapid prototyping
  • Mechanical testing
  • Production-ready output files

Phase 1 — Analysis & Measurement

The existing part was disassembled and measured using calipers and reference tools.

Key findings:

  • Inconsistent wall thickness
  • Weak rib structure
  • Mounting holes misaligned relative to assembly datum
  • Stress points concentrated near fastener zones

The geometry was reconstructed in CAD from scratch rather than modified directly to ensure dimensional clarity.

Phase 2 — Engineering Redesign

The updated design focused on:

  • Corrected tolerances for fit and assembly
  • Reinforced rib geometry
  • Improved wall thickness distribution
  • Filleted internal corners to reduce stress concentration
  • Optimized material usage

Design decisions were informed by real fabrication constraints — not theoretical modeling alone.

Phase 3 — Prototype & Validation

The redesigned component was prototyped using additive manufacturing to validate:

  • Fit with existing assembly
  • Fastener alignment
  • Structural integrity under manual stress
  • Installation workflow

Multiple iterations were tested to refine:

  • Hole tolerance
  • Interference fit
  • Material thickness

Phase 4 — Production Preparation

Once validated, the component was finalized for scalable manufacturing.

Deliverables included:

  • Clean production CAD files
  • Tolerance documentation
  • Material recommendations
  • Assembly references
  • Fabrication-ready outputs

The final design reduced structural failure risk and improved assembly consistency.

Final Output

  • Reinforced mechanical housing
  • Corrected geometry
  • Improved manufacturability
  • Production-ready design package
