Product Design
Ergonomic Medical Device Housing Prototype
Created the industrial design and mechanical enclosure for a handheld clinical blood analyzer. The housing balances medical-grade chemical resistance (isopropyl wipe-down), tactile grip ergonomics, and strict IP67 water ingress protection.

Engineering Challenge
The device needed to survive a 2-meter fall onto concrete while remaining completely sealed against liquid sterilizers.
Applied CAD & DFM Solution
Designed an internal elastomeric floating chassis skeleton surrounded by a rigid PC/ABS shell with molded-in elastomeric ribs and ultrasonic weld joint beads.
Key Modeling & Surfacing Highlights
Complex Curvature-continuous Class-A surfacing for ergonomic thumb grips
SolidWorks Plastics mold fill simulation to prevent sink marks and knit lines
Tolerance stack-up analysis across 14 plastic component interfaces
