Integrated Product Development - Material Science - Cost Management - Project Management - Prototype Fabrication - Product Testing - Project Reporting: Successfully Co-Led Team to Develop, Design & Manufacture a Prototype Dog Toy on Time & Within Budget, Texas Tech Whitacre School of Mechanical Engineering, Capstone Project:

Performance Standards: Must roll farther than most balls that are currently marketed or commonly used for this purpose when thrown by persons with range-of-motion limitations.

Design Standards & Technical Specification: Pet-safe, non-toxic, low-cost, highly-durable, floats in water, puncture & tear resistant but also soft on the dog's mouth.

Product Development: Research health & safety requirements and consumer priorities to help develop design specifications & performance objectives.

Material Science: Evaluate alternative materials & designs to ensure safety, design, cost & performance criteria could be achieved.

Cost & Project Management: Develop a project plan, Bill of Materials, timeline & milestones, then track progress & budget vs. plan.

Prototype Fabrication: Oblate spheroid composed of durable, non-toxic Dragonskin silicone rubber outer shell; lightweight, non-toxic Speedy Foam solid core; dimensions comfortable for small dogs & unlikely to be swallowed by large dogs. Designed and produced cast in a 3D printed mold.

Product Testing: Develop field tests & measurements to evaluate performance vs. criteria.

Project Reporting & Technical Documentation: Written status reports & presentations throughout project. Final technical report.

Results: Heavier shell increased the moment of inertia, allowing the toy to roll almost 2x farther than a tennis ball given the same input force. Solid, more compressible & less dense core allowed toy to float as if hollow while much more resistant to puncture. Field testing produced zero punctures, tears or visible wear. Elastic materials provided significant bounce, reducing the time the toy was in contact with the ground & increasing the distance traveled. Elasticity and oblate shape allowed it to move over

& past obstacles and maintain its momentum.

PRACTICAL ENGINEERING EXPERIENCE

Successfully Co-Led Team to Design - Plan - Fabricate a Product to Specification Texas Tech Whitacre School of Mechanical Engineering, Manufacturing Processes Project:

Design Standards & Technical Specification: From multiple scraps of steel & aluminum, construct a frame that would hold a 4-part assembly in place at specified positions & angles while the assembly's unattached pieces are welded together by hand.

Design & Plan: Visualize assembly in 3D, design pieces, verify that design would permit a welder & their equipment to access external locations of assembly, determine how to hold assembly together in proper position during the welding process, prepare plans for the assembly, set steps of fabrication once pieces constructed.

Fabricate: Use manual lathe & router to fabricate pieces to team-set specifications, utilize plan for each step of putting the assembly together so that the ring would remain in position.

Results: Team fabricated a 2-part frame. The first part allowed the 2 L-shaped legs of the assembly to be welded to the horizontal base of the assembly. The legs and base of the assembly slotted into the frame on their sides, holding the assembly firmly together before welding. An aluminum peg was turned to center and hold a steel ring in place while it was spot welded to the top of the assembly. The assembly pieces were held firmly throughout welding, and were able to be removed from the frame with ease once connected.
