Bicycle Frame Accessory Tube for Integrated Locking and Clamping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bicycle frames face issues with wear and damage due to separate accessories, which can be cumbersome and reduce durability and convenience, particularly in the clamping mechanism, steering lock, and lock chain usage.
Innovation Solution
Incorporating an accessory tube that houses a clamping mechanism, steering lock mechanism, lock chain guide, and chain lock mechanism, allowing for a compact, modular design that simplifies operation and enhances security, with integrated lighting and power supply options.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate accessories (clamping mechanism, steering lock, lock chain) are used, then the frame provides basic functionality, but the accessories are subject to wear and damage reducing durability and reliability
Solution Approach 1:
The patent combines the clamping mechanism, steering lock mechanism, and lock chain guide into a single integrated accessory tube assembly. This merging of previously separate accessories into one unified component reduces the number of individual parts that can wear or damage, thereby improving reliability while simplifying the overall device structure.
Solution Approach 2:
The accessory tube serves multiple functions simultaneously: it houses the clamping mechanism for the saddle pin, contains the steering lock mechanism, and provides a guide for the lock chain. This multi-functional design eliminates the need for separate dedicated components for each function, reducing complexity and improving reliability through consolidation.
2Ease of operation
If a clamping mechanism is arranged on the upper end of the saddle tube, then the saddle pin can be clamped, but the seat tube must protrude above the upper tube which is aesthetically undesirable
Solution Approach 1:
The clamping mechanism is nested within the accessory tube, which itself is integrated into the frame structure. This nesting allows the clamping mechanism to be hidden inside the tube rather than protruding externally, maintaining the frame's aesthetic appearance while preserving the saddle positioning functionality.
Solution Approach 2:
The clamping mechanism is extracted from its traditional external position on the upper tube and relocated inside the accessory tube. This extraction allows the mechanism to remain functional while being concealed within the frame structure, eliminating the unsightly protrusion.
3Ease of operation
If steering lock and lock chain are used as separate accessories, then basic security is provided, but the threshold for locking the cycle is reduced and convenience is improved when integrated
Solution Approach 1:
The steering lock mechanism and lock chain guide are merged into the same accessory tube assembly, allowing both security functions to be operated from a single location. This integration improves convenience by reducing the threshold for locking operations, as users can access both functions through one unified interface rather than managing separate accessories.
