MECHANICAL ENGINEER
Product Design CAD Design Product Development Mechanical Design Adept mechanical engineer with 10+ years experience and a strong background in product development. Have brought new revenue to past companies by helping to introduce new products and expand existing product lines, as well as making modifications to existing product to improve design and reduce cost. Good team player that is easy to get along with and a good resource for design evaluation. Some key skills that will help you get your products to market are:
Familiar with common tasks and logistics required to plan project schedules from concept to production.
Experience designing plastic and metal parts and assemblies (e.g., brackets, enclosures, wire harnesses, heat spreaders, stamped & formed metal parts).
Experience conducting stress and thermal analyses to optimize designs (e.g., extreme pipe pressure, heat-sink dissipation, solar panel in wind, g-forces).
Experience using CAD software to conceptualize, create mechanical drawings, simulate behavior. Most familiar with SolidWorks (9000+ hours).
Experience conducting tolerance analyses to verify fit between mating parts.
Experience applying engineering principles to predict physical behavior.
Experience formulating environmental test plans per MIL-STD-810G and IEC.
Experience applying method of GD & T per ANSI Y14.5 to dimension parts. PROFESSIONAL EXPERIENCE
SABBATICAL Feb 2015- Present
Took a leave of absence to travel for six months but was downsized in meantime due to economic reasons. Using free time to improve skills. FREEWAVE TECHNOLOGIES, Boulder CO (radios) Aug 2008-Feb 2015 Mechanical Engineer
Helped design and introduce three new radio products to increase company revenue: I/O Expansion, Wave Contact, and Spartan (see website).
Designed several plastic and metal parts and assemblies:
2-piece plastic enclosure with interlocking snaps, sliding DIN rail mechanism, acrylic light pipes, heat spreader.
RF cables and wire harnesses (e.g., potted explosion-proof wire harness).
Mechanical layouts for printed circuit boards (e.g., shapes, connector selection, board fastening and stacking, panel layouts).
Conducted stress and thermal analyses to evaluate effects of g-forces, vibration, insolation, heat dissipation on several mechanical parts (e.g., pcb bracket, plastic cover for battery pack, heat spreader).
Conducted tolerance stack-up analyses to check fit of mating parts (e.g., fit between heat spreader, thermal pad, and microprocessor). Patrick Johnston
