Adapted Recumbent Bike, Kurtis Mundell, Dane Tiemeier, Laura Yakuma, Darius Yu Dec 2010

Adapted Recumbent Bike, Kurtis Mundell, Dane Tiemeier, Laura Yakuma, Darius Yu

Mechanical Engineering

The adapted recumbent project was to redesign a disabled veteran’s recumbent bicycle. The main areas of concern were the crank pedal, chain tension, braking and steering system, and ergonomics. Since the customer is an avid biker, this bike will be used often, so the design is based on the ease of repair and replacement. The crank system was redesigned to a lightweight, adjustable part with chain clearance and high strength. The chain tension was improved by replacing the existing single idler wheel/chain tube system with a dual idler wheel system. The dual idler has a titanium sprocket in one of …


Design Of A Low Cost Powered R/C Combat Airplane And Manufacturing Plan, Jonathan N. Bailey Jan 2010

Design Of A Low Cost Powered R/C Combat Airplane And Manufacturing Plan, Jonathan N. Bailey

Industrial and Manufacturing Engineering

The goals of this project are to design a low cost powered remote control combat airplane capable of outdoor flight, named the Aero EX and to develop a manufacturing plan to produce each unit at a selling price of $200, while operating at a 25 vehicle batch rate inside a 1,000 square foot facility. These goals are achieved using: Aerospace fundamentals to design the vehicle, Design for Manufacturability to optimize the design for minimal use of labor, Design for Assembly to give consumers the ability to build the vehicle without fixtures, Pull production to eliminate scheduling and match customer demand. …


Design For Manufacturing Of Sports Equipment, Cedrick Bit, Christopher L. Head Jan 2010

Design For Manufacturing Of Sports Equipment, Cedrick Bit, Christopher L. Head

Industrial and Manufacturing Engineering

The purpose of this project was to validate industrial designs for a product in its conceptual stage and suggest/implement design changes that suit the contracting company’s needs while assuring the product maintains its basic functional requirements. Techniques and methods used to validate the design include 3‐D solid modeling, physical product application using rapid prototyping to produce the product. Methods of design for manufacturing were analyzed in the design. Processes used in the validation and verification of the design include solid modeling design, methods of measurements, fixture design and manufacturing processes. Full design specifications and solid model files were finalized and …
