Rotating U-Lock Bracket for Compact Secure Bicycle Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing U-lock brackets for bicycles are either too bulky to be convenient for transport or lack flexibility in accommodating different U-lock designs, and they often fail to securely attach the lock without risking accidental detachment during use.
Innovation Solution
A bracket with a rotatable insert part that allows for easy attachment and secure clamping of U-lock shackles by rotating the insert from an insertion position to a locking position, ensuring the U-lock is held firmly in place without rattling, and accommodating various U-lock shapes and sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the bracket is designed to be compact for convenient transport, then the bracket size is reduced, but the reliability of U-lock attachment may deteriorate
Solution Approach 1:
The insert part is designed to be rotatable relative to the housing, transitioning between an insertion position (where the receiving space is open for easy insertion) and a locking position (where the receiving space is closed for secure attachment). This dynamic mechanism allows the bracket to provide both compact storage and reliable attachment without requiring a large overall structure.
2Adaptability or versatility
If the bracket is designed to accommodate various U-lock designs, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The receiving space is designed with a universal geometry that can accommodate different shackle cross-sections (circular, rectangular, square) and sizes. The rotatable insert part maintains a consistent clamping mechanism that works with various U-lock designs without requiring multiple specialized components, thus achieving versatility without proportionally increasing complexity.
3Ease of operation
If the bracket uses a simple insertion mechanism, then the ease of operation is improved, but the security against accidental detachment deteriorates
Solution Approach 1:
The simple rotary insertion mechanism transforms an initially open receiving space into a closed clamping position through rotation. The ease of operation is maintained through the simple rotational motion, while the security against accidental detachment is achieved by the closed position of the insert part that positively engages and clamps the shackle, preventing unintended removal.

AI summary
The invention relates to a mounting for fastening an allocated D-lock, having a lock body and a loop, to a two-wheeler, more particularly to a bicycle, comprising a housing extending along a longitudinal axis and an insert part which is arranged at least partially within the housing and can be rotated relative to the housing about an axis of rotation between an insertion rotation position and a locked rotation position. The mounting has a receiving space for one leg of the loop into which receiving space the leg can be inserted in the insertion rotation position, wherein the leg inserted in the receiving space can be clamped in the receiving space by rotating the insertion part out of the insertion rotation position into the locked rotation position.
