Problem
Existing cable adjusting devices for vehicles, such as bicycles, have complex structures leading to high costs and complicated assembly processes, which result in increased manufacturing costs and operational complexity.
Innovation Solution
A cable adjusting device comprising a first sleeve with a first opening and a second sleeve with a stop portion and through hole, allowing for easy adjustment of tension between the outer tube and wire through relative rotation, utilizing a simple structure with thermoplastic materials for lightweight, low-cost, and low-friction operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a complicated structure with multiple parts is used, then the structural strength is improved, but the manufacturing cost and assembly complexity increase
Solution Approach 1:
The patent integrates multiple functional components into a unified cable adjusting device structure. The housing contains both the cable guide and adjustment mechanism, while the clamp assembly combines clamping and positioning functions in a single integrated component. This merging reduces the number of separate parts that need to be manufactured and assembled, directly addressing the contradiction between structural strength and assembly complexity.
Solution Approach 2:
The device is segmented into distinct functional modules: a housing containing the cable guide, a separate clamp assembly with adjustment mechanism, and integrated stop portions. This segmentation allows each component to be optimized for its specific function while maintaining overall structural integrity, reducing assembly complexity compared to a monolithic design.
2Adaptability or versatility
If multiple parts are manufactured and assembled, then the functional requirements are met, but the manufacturing cost increases
Solution Approach 1:
Multiple functions are merged into fewer components. The housing simultaneously provides structural support, guides the cable, and contains the adjustment mechanism. The clamp assembly integrates clamping, positioning via stop portions, and adjustment capabilities. This functional merging reduces the number of parts that need to be manufactured and assembled, lowering manufacturing costs while maintaining all necessary functions.
3Ease of manufacture
If a simple structure is used, then the manufacturing cost is reduced, but the frictional resistance increases
Solution Approach 1:
The patent applies local quality optimization by providing smooth, finished surfaces specifically at the cable guide interface and contact surfaces within the clamp assembly. These localized smooth surfaces reduce frictional resistance where the cable passes through and where moving components contact each other, while the overall structure remains simple and cost-effective.
4Stability of the object's composition
If a complicated assembly process is used, then the structural integrity is ensured, but the installation time increases
Solution Approach 1:
The integration of the cable guide within the housing and the clamp assembly with built-in stop portions creates a unified structure that maintains structural integrity while reducing the number of assembly steps. The stop portions are pre-integrated into the clamp assembly, eliminating separate positioning operations during installation.
