Ongoing refinement
Boogie Bikes LLC
Design a low-profile, easy-to-manufacture U-lock holder that can be attached to the existing rack.
A thin clamp that zip-ties to the frame and tightens the clamp to the rack while also tightening the U-lock.
Driving Constraint
The most important constraint given to this project was speed and manufacturability. At the project's start, the plan was to cast the lock clamp in aluminum. By the end of the project, the manufacturing was changed to 3D printing, which impacted the design.
Iteration
After I determined the initial design to be a thin clamping mechanism that fixes to the bike rack, I 3D printed and tested a total of 11 different iterations. Here are three snapshots of the more major changes that developed through testing.
