Identify high-stress regions and recommend fillet radii, reinforcement strategies, and geometry refinement
Suggest material substitutions and topology changes to reduce weight while maintaining performance
Flag design features that may cause machining issues, casting defects, or assembly problems
Compare design alternatives on performance, manufacturability, cost, and lead time
Generate prioritized design change recommendations based on impact and implementation effort
Example Output
Design Review Summary
Model: Housing Assembly v2.3
Key Findings:
- ✅ Wall thickness (2.2mm) adequate for injection molding
- ⚠️ Stress concentration at corner radius R=0.5mm (peak: 285 MPa)
- ⚠️ Ribs support edges but interior cavity spans 80mm unsupported
Optimization Recommendations:
- Increase fillet radius to R=1.5mm → reduces peak stress to 165 MPa (42% reduction)
- Add center rib (1.0mm tall) → improves modal frequency from 127 Hz to 312 Hz
- Switch to PA66 GF30 → 18% weight savings vs. current ABS (95g → 78g)
Manufacturing Impact: +$0.08/unit tooling, -15 seconds cycle time
Revised Estimate: Performance ↑22% | Cost ↑3% | Lead time -2 weeks
