Battery Charger User Testing (3D prototypes)

Problem

R&D needed a new hospital battery charger enclosure that could hold multiple batteries, fit a small footprint, and give clear tactile feedback when batteries were correctly seated.

Solution

I designed 11 candidate enclosures in Rhino 3D for both countertop and wall-mount use, then had each one 3D printed, weighted, and painted to spec. Testing with battery packs revealed that users strongly preferred models with additional USB charging ports.

Tools

Rhino 3D, Keyshot, Solidworks
