Bicycle Headset Cable Routing Assembly for Sealed Two-Piece Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cable routing bases on bicycles are difficult to assemble and prone to ingress of foreign objects like moisture and dust due to non-parallel cable holes and exposed routing, affecting appearance and safety.
Innovation Solution
A two-piece cable routing assembly with non-parallel axial and channel directions, featuring annular bases with grooves and plugs to guide and seal cables, preventing foreign object ingress and facilitating assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional cable routing base with cable holes is used, then the cable can pass through and be positioned, but the cable direction cannot be easily determined and assembly is difficult
Solution Approach 1:
The cable routing base is divided into a first base and a second base that can be separately assembled. The cable is first positioned in the cable groove of the first base, then the second base is engaged with the first base to complete assembly. This segmentation makes the assembly process easier and the cable direction more determinable.
2Ease of operation
If cable holes are provided in the cable routing base, then the cable can pass through, but foreign objects like moisture or dust can easily enter and cannot be easily removed
Solution Approach 1:
The cable is pre-positioned in the cable groove of the first base before the second base is engaged. This preliminary positioning ensures the cable is correctly placed before sealing, and the subsequent engagement of the two bases creates a sealed structure that prevents foreign object ingress.
Solution Approach 2:
The cable is nested within the cable groove formed by the first and second bases. The cable groove is positioned within the internal space formed by the two bases, creating a protected pathway that prevents foreign objects from reaching the cable while allowing it to pass through.
3Device complexity
If the cable is disposed outside the frame, then the cable routing is simple, but the appearance is affected and the cable is easily contacted or tangled with external objects
Solution Approach 1:
The cable is nested within the cable groove that is formed by the first and second bases. This groove is positioned within the internal space of the cable routing base, effectively hiding the cable from external contact while maintaining a simple routing structure. The cable passes through the base internally rather than being exposed externally.

AI summary
A cable routing assembly, disposed on a headset of a bicycle and having a through hole fitting around a steerer tube of the bicycle, includes a top annular base having a first through hole and a first cable groove and a bottom annular base having a second through hole and a second cable groove. When the top annular base is engaged with the bottom annular base, the top annular base and the bottom annular base jointly form an internal space, and the first cable groove and the second cable groove jointly surround to form a cable channel communicating between an external space and the internal space. The first through hole communicates with the second through hole to form the through hole. An axial direction and a channel direction that are not parallel are defined. The through hole extends along the axial direction. The cable channel extends along the channel direction.
