Razor Redesign Statement of Purpose: The scooter in todays society is thought of as a toy for kids. We believe that it can be more than that and be used as a valid form of transportation around college campuses with a few modifications. Product Function: Scooters are made for short term transportation as well as for fun. It can be used on the streets as well as in skateparks. Most commonly, scooters are used by kids to ride on the streets with their friends. Picture from Razor.com Figure 1: Razor Scooter Reverse Engineering: We took apart the scooter from the top to the bottom unscrewing all of the allen screws and pulling apart all of the major pieces. It turned out to be about 4 major pieces which were the inner shaft, the outer shaft, the central pivot, and the base. ! ! Materials Used: • Metals: Steel and aluminum • Plastics: acrylonitrile butadiene styrene, polyurethane ! Manufacturing Processes Employed: • Metals: Extrusion, stamping, forging, MIM, diecasting • Plastic Processes: injection molding Made by Glen Foster on Google SketchUp Figure 2: Exploded View of scooter Customer Analysis: Our customer is a college student between 5’4” and 6’3”. The requirements are taller handlebars, bigger and more sturdy wheels, longer and wider base, and a hand brake. ! Engineering Specifications: We made these engineering specifications to set the standards for our redesiegned scooter. • Handlebars that can reach the bellybutton of a person that is 5’4” as well as a person who is 6’3” and all of the heights in between. • Stable wheels that dont get caught on small rocks or cracks in the road at 196 mm • Scooter that can hold up to 350 lbs. • wide handlebars at 18 in. to be able to balance Final Sketch of Refined Redesign Concept (10” x 14”) ! Conceptual Design: we wanted to make a scooter that all college kids felt that they could ride. we used Glen as our consumer to make sure he was able to ride the scooter. Knowing that he could ride the scooter, everyone else smaller than him would then be able to ride it as well. ! Cost Analysis: If we were to redesign this, we estimate that production would be about $32.23. $4 for the aluminum pipes, $17.23 for the base, $6 for the wheels, and $5 for the others like the brake, foam padding, plastic covers, and the hardware.
