Define the Problem
Problem StatementAccording to the US Department of Transportation’s National Highway Traffic Safety Administration (NHTSA), approximately 57 million people in the United States rode a bicycle in the year 2002. The first bicycle that used a chain was invented in 1885. This resulted in the problem of bicycle chains falling off the gears. In a class of 27 students, 20 agree that bicycle chains falling is a problem that occurs very often and should be solved.

Brainstorming
Determined what specifically causes chains to fall off
Create possible designsNo restraintsAll ideas welcome
Build off team members’ ideas for best preliminary designs
![Page 12: Hang Tight TEAM REMAKE Kelsey Barrera Mitch Reid Rishi Savaliya](https://reader035.vdocument.in/reader035/viewer/2022062805/5697c0101a28abf838ccb0df/html5/thumbnails/12.jpg)
Research
Why do bike chains fall off?Decreased tension makes the chain
looseMisalignment of the chain and sprockets
Does not mean a bike cannot be used
