Bidirectional Quick-Release Buckle for Balanced Length Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional buckle-type quick releases have limited adjustability, allowing length adjustment only at one end, which restricts their adaptability to various bicycle frames of different widths, leading to potential unbalance and reduced usability.
Innovation Solution
A buckle-type quick release design with bidirectional length adjustability, featuring an adjusting bolt and screwing rod that can be rotated to adjust the length at both ends, utilizing a ringlike spring and eccentric screwing component for enhanced adjustability and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If length adjustment is provided at only one end of the quick release, then the structure is simple, but the adjustment range is limited and adaptability to various bicycle frames is reduced
Solution Approach 1:
The quick release mechanism is divided into two independent adjustment systems: one at each end of the shaft. Each end has its own adjusting bolt (first adjusting bolt at one end, second adjusting bolt at the other end) that can independently adjust the length. This segmentation allows bidirectional adjustment capability while maintaining relatively simple individual components, resolving the contradiction between adaptability and structural complexity.
2Length of moving object
If the adjusting bolt is rotated to change the length at one end, then length adjustability is achieved, but the shaft becomes excessively remote from one side and overall adjustment range is limited
Solution Approach 1:
The patent employs asymmetric adjustment by allowing different adjustment amounts at each end of the shaft. The first adjusting bolt and second adjusting bolt can be rotated independently to different extents, enabling the shaft to be positioned correctly on asymmetric bicycle frames. This resolves the limitation of unidirectional adjustment while maintaining shaft position stability through balanced counter-adjustment.
3Ease of operation
If a conventional single-end adjustment system is used, then the device is easy to operate, but the usability is reduced due to limited adjustment capacity
Solution Approach 1:
The quick release mechanism allows users to independently adjust each end of the shaft according to the specific width requirements of the bicycle frame. The first and second adjusting bolts can be operated separately without requiring complex coordinated adjustments, enabling users to self-adjust the length to achieve optimal fit and usability for different frame widths while maintaining operational simplicity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The bidirectional adjustability allows for improved usability and adaptability to different bicycle frame widths, ensuring even length adjustment and preventing unbalance, thus enhancing structural stability and reducing maintenance costs.
Implementation Method 1
a ringlike spring, wherein, during fabrication, the ringlike spring is placed into the channel, and then the movable sleeve is mounted around the end of the shaft away from the adjusting bolt through the opening, such that the ringlike spring has one end abutting against the shaft and an opposite end abutting against the movable sleeve
Implementation Method 2
an adjusting bolt, having an external threaded segment and being provided at one end with a plug head, wherein the external threaded segment of the adjusting bolt is made to be screwedly engaged with the first-end internally threaded segment of the axial hole

AI summary
A buckle-type quick release with bidirectional length adjustability includes a shaft, defining an axial hole that has a wall formed with a first-end internally threaded segment and a second-end internally threaded segment; an adjusting bolt, having an external threaded segment that is made to be screwedly engaged with the first-end internally threaded segment of the axial hole; a movable sleeve, defining therein a channel made to receive a ringlike spring and is made to be mounted around the shaft; and an eccentric screwing component, having an eccentrically rotatable quick-release lever and a screwing rod formed with an external threaded segment, so that the external threaded segment of the screwing rod after passing through the movable sleeve and the ringlike spring can be screwedly engaged with the second-end internally threaded segment of the axial hole. The quick release has its length adjustable in two opposite directions and has improved usability.
