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.

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.

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.
