Rubbermaid Shotgun Butterfly Mop 

This unique mop designed in-house for Rubbermaid combined shotgun-style actuation with a butterfly-style compression mechanism. During informal comparisons to other units, the ID model for this design (assembled, vacuum-formed polypropylene parts) yielded superior sponge compression with less user effort. Molded-in hooks for loop-style sponge pads not only simplified removal and clean-up, but also reinforced Rubbermaid's sponge replacement business. To lower assembly costs parts were designed with living hinges and molded-in snap fasteners. The design was delivered as a near "tooling-ready" Pro/E file; including 7-degree shutoff angles and an equation of motion written as a relation within the file to confirm operation and conduct virtual interference checks. Development program: concept ideation, Pro/E geometry for model/rendering/tooling, Alias renderings, significant liaison with in-house manufacturing group
