The Cycle Caddy was improved upon Mid-March 2020. It's a bicycle carriage rack that also works as a mudguard and a lockable storage space. Taking into account information learned from observation, interviews, market research, and user research, the Cycle Caddy is a permanent solution for bike accessory theft, rear tire splash, safety, and away from home repairs.
During the 2020 spring break, I improved on the design's features with a key fob locking mechanism and solar-powered battery storage. This addresses two issues identified in the previous prototype:
The old mechanical lock would get in the way on the carriage surface
The LED light would need replacement batteries.
For these components, I sourced a key fob cabinet lock and portable solar-powered USB battery bank from and wired them as necessary to work in the functional prototype. One feature I included in the wiring is conductive strips on the underside of the carrier surface, enabling the solar-powered battery to continue charging while the drawer is open or closed. This 'wireless' configuration enables removal of the drawer entirely from the cycle caddy housing. Lastly, if the portable battery dies, the user may manually recharge it.
Here the solar panel charges the battery while the drawer is open.
I've recently found an interest in additive manufacturing, so I invested in my own 3D printer to accelerate my prototyping process and force myself to more frequently use 3D modeling software in my design process. The exterior body of this prototype was printed in PLA.
