Bicycle Bottom Bracket With Integrated Compressed Air Bottle Mount
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional inflators for bicycles are cumbersome and slow, and while compressed air bottles offer a solution for rapid tire inflation, they are small and lightweight, making them easy to lose or difficult to locate during a ride.
Innovation Solution
A bicycle frame design with a bottom bracket that incorporates joint holes to securely attach a compressed air bottle, using threaded connections and a blocking lever for stability and safety, allowing easy assembly and carrying of the bottle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional inflator is carried, then tire repair capability is provided, but the device is bulky and inconvenient to carry
Solution Approach 1:
The invention extracts the compressed air bottle from the conventional inflator assembly, separating the air storage function from the inflating mechanism. This allows the air bottle to be miniaturized and carried independently while attached to the bicycle frame, eliminating the need to carry a bulky conventional inflator.
Solution Approach 2:
The compressed air is pre-filled into the bottle before the tire repair is needed. The bottle is attached to the bicycle frame in advance, so when a puncture occurs, the rider can immediately use the pre-prepared air source without needing to carry or assemble a large inflator device.
2Volume of moving object
If a compressed air bottle is used, then the size and weight are reduced, but the bottle is easy to lose or misplace
Solution Approach 1:
The invention merges the compressed air bottle with the bicycle frame by providing a dedicated mounting structure. The bottle is integrated into the frame geometry, combining two separate objects (bottle and frame) into a unified system where the bottle becomes a fixed component of the bicycle.
Solution Approach 2:
The invention introduces a mounting bracket or holder as an intermediary component between the compressed air bottle and the bicycle frame. This mediator securely attaches the bottle to the frame, preventing it from being lost while still allowing for easy removal when needed.
3Weight of moving object
If the compressed air bottle is carried separately, then it is lightweight, but time is spent looking for it during tire repair
Solution Approach 1:
The compressed air bottle is pre-positioned and attached to a fixed location on the bicycle frame before the tire repair is needed. This preliminary positioning eliminates the need to search for the bottle during the repair process, as it is already in its designated spot.
Solution Approach 2:
The mounting structure on the bicycle frame serves multiple functions: it secures the compressed air bottle during normal riding, positions it for easy access during tire repair, and integrates it into the overall bicycle system. This multi-functional design ensures the bottle remains accessible and visible at all times.
