On 3 person team that investigated new technologies and platforms. Evaluated feasibility, developed POC protos, and delivered detailed designs to product development for implementation. Extensive use of first principles/physics based math model creation to describe problems and solutions.

Tualatin, Oregon

-Owned design/development of multiple mechanical and electro-mechanical sub-systems-Leveraged first principles based hand calcs/math models/simulation to characterize statics, dynamics, and vibrations-Hands on prototyping with mill, lathe, 3D print, welding, etc.-Designed and executed tests to verify system function-Designed for injection molding, compression molding, over/insert molding, powder metallurgy, MIM, sheet metal, weldments, extrusion, machined, wood, laminates-Presentation of status/design/testing/models/etc. to cross-functional teams and leadership-Collaboration with EE/SW team-DFM with Asian suppliers-FPI process ownership

Portland, Oregon Area

Part of 3 person team that designed a cost-reduced automated gelatin-shot making machine. -Designed for plastic injection molding, sheet metal, silicone rubber, machining, electrical harnesses, water/gelatin tubing networks-DFM discussions with Chinese manufacturers-Designed pulley-driven gelatin dispense arm system-Designed power/electrical enclosure-Created and verified model for water flow rate at outlets as a function of water input pressure-Created and verified model for water heater tank temperature as a function of time

Orange County, California Area

Ownership of product design/development for new atraumatic grasping device from concept to tooling release. Product highlights include:-Device limits max end effector force below trauma inducing level regardless of user actuation force, rather than relying on user limiting their actuation force-Cost savings over previously released atraumatic grasper-Eliminated failure modes of concern for previously released atraumatic grasper

Orange County, California Area

-Qualified new production processes, equipment, fixtures, product design changes-Designed fixtures and gauges to improve assembly efficiency-Evaluated customer returned product failures for root cause-Updated product designs to improve product performance, cost, production efficiency-Resolved non-conformances at raw material, part, assembly levels with dispositions and corrective/preventative action measures-Troubleshooting team lead for several high visibility production product issues-Met with surgeons to discuss their device issues, observe their device usage, and determine root cause of issues-Supervised Engineering Technicians
