STATUSTooling & Production Ready
01 / CLIENT SPECIFICATION
A commercial client required the development and production readiness of a specialized manual drywall scoring and cutting instrument. Starting from rough physical mockups, the objective was to re-engineer the geometry for improved operator ergonomics, rigorous blade stability, and cost-effective CNC and injection molding fabrication.
02 / CAD MODELING & ERGONOMIC OPTIMIZATION
- ■Reverse Engineering: Digitized physical reference components into parametric 3D CAD assemblies.
- ■Iterative Ergonomics: Refined grip profiles and hand-clearance geometry to minimize repetitive wrist strain during continuous sheet scoring.
- ■Virtual Prototyping: Conducted digital interference checks and tolerance stackup simulations to ensure zero blade play under load.
03 / PRODUCTION DOCUMENTATION
Transitioned the approved assembly into a comprehensive manufacturing handoff package:
- ■Detailed Engineering Drawings: Created complete 2D blueprints detailing geometric dimensions, datum references, and surface roughness specifications.
- ■Tolerance Specifications: Defined critical fit tolerances to ensure interchangeable parts across multi-cavity production runs.
- ■Material Callouts: Selected alloy compositions and hardening heat treatments suited to drywall gypsum dust exposure.
