My key contributions
Full mechanical design (from prototype to manufacturing) of hand piece including internal mechanisms and integration into outside shape from industrial designers
Fully custom XYZ stage
Integration of PCBs and collaboration with EE team for optimal design
Shell topology: clamshell split, IP22 sealing, EMI shielding, press fit screw caps, LED illumination, cabling strain relief, industrial design tweaks for assembly feasibility
DFM of outer shell (injection molding) and disposable parts
Led development of disposables technology (needle hub and vacuum frame)
Vacuum flow analysis
Disposable usability and efficacy
Alpha Build Production Hand Piece
Clip on, 3 piece, patient contacting disposable
