Bicycle Headset Tool Storage via Nested Top Cap
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bicycle tool storage solutions are inadequate as they often compromise the structural integrity of the steerer tube, are cumbersome, and expose tools to dirt and debris, leading to accessibility and safety issues during rides.
Innovation Solution
A portable top cap and bicycle pump design that incorporates a tool storage device with a flange and O-ring system for secure, sealed storage within the headset assembly or pump, maintaining structural integrity and protecting tools from damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If tools are mounted to the bike frame, then tools are easily accessible during rides, but the bike aesthetics are compromised and tools are exposed to dirt and debris
Solution Approach 1:
The tool storage device is nested inside the headset assembly, specifically within the top cap structure. The tools are stored in a recessed cavity formed by the top cap and spacer, effectively hiding them within the existing bike components rather than mounting them externally on the frame.
2Ease of operation
If tools are mounted to the bike frame, then tools are easily accessible during rides, but tools are susceptible to falling off and being lost
Solution Approach 1:
The tools are nested within the enclosed cavity of the headset assembly, surrounded by the top cap and spacer structure. This nested configuration provides inherent retention, preventing tools from falling off during rides while maintaining easy access when needed.
Solution Approach 2:
The tool storage function is merged with the existing headset assembly structure. The top cap and spacer components serve dual purposes: maintaining headset functionality and providing a secure storage cavity for tools, combining two functions into one integrated system.
3Volume of moving object
If a top cap and spacer are used to optimize axial length, then headset assembly is compact, but no internal space is available for tool storage
Solution Approach 1:
The tool storage cavity is created in a specific local region within the headset assembly, utilizing the space between the top cap and spacer. This localized cavity formation allows tool storage without increasing the overall axial length of the headset assembly, maintaining compactness while adding functionality.
Solution Approach 2:
The top cap and spacer components perform multiple functions: maintaining proper axial length for headset assembly, providing structural support, and creating an enclosed storage cavity for tools. This multi-functionality allows the same components to serve both dimensional and storage purposes.
4Reliability
If the steerer tube is extensively threaded to mount devices, then device mounting is secure, but the structural integrity of the steerer tube is compromised
Solution Approach 1:
The device mounting function is extracted from the steerer tube and relocated to the top cap assembly. The top cap provides the mounting interface for tools and accessories, eliminating the need to thread the steerer tube extensively and preserving its structural integrity while maintaining secure mounting capability.

AI summary
The present invention provides a bicycle tool storage device mountable in a bicycle headset assembly and/or a bicycle pump. A top cap for loading a headset assembly and mounting the device is also provided. The top cap includes an annular body and a device receiving aperture extending through the body. The top cap includes a flange extending radially outwardly from a first end of the body and a ridge defined in an inner surface of the body adjacent to the flange. The ridge is concentrically aligned with the aperture for retaining the device. Further still, a bicycle pump for mounting the device is provided. The pump includes a pump body, a handle, a pump head, and a flange. The pump body houses a plunger and a piston. The plunger and handle define a cavity for receiving the device. The handle further defines a flange for retaining the device.
