Bicycle Lock Holder With Transverse Support Element
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mounting arrangements for folding bicycle locks face challenges such as difficulty in universal use across different lock sizes, limited length accommodation, and undesirable shaking noises due to manufacturing tolerances and play.
Innovation Solution
A mounting arrangement featuring a support element that protrudes along a transverse axis, engaging in a recess of the lock, and a pivotable fixing element with elastic properties, allowing for secure fixation and easy handling of bicycle locks of varying lengths without play, thereby preventing unauthorized removal and reducing vibrations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a movable fixing element is used to secure the bicycle lock, then the lock can be firmly fixed in the receiving area, but the handling becomes more complex and requires additional steps
Solution Approach 1:
The fixing element is designed as a movable component that can transition between open and closed positions, allowing dynamic adjustment for both easy insertion and secure fixation of the bicycle lock
Solution Approach 2:
The mounting arrangement is designed to guide the fixing element into the correct position automatically during insertion, reducing the need for precise manual alignment and simplifying the operation for the user
2Reliability
If a pocket or bearing shell is used to support the bicycle lock, then the lock can be held in place, but the length accommodation is limited and universal use is restricted
Solution Approach 1:
The mounting arrangement is designed with a standardized interface that can accommodate different types and sizes of bicycle locks, making it universally applicable across various lock models while maintaining stable positioning
Solution Approach 2:
Instead of limiting support to a single point or narrow shell, the support element extends along the longitudinal axis of the carrier, providing distributed support that adapts to locks of varying lengths without compromising stability
3Device complexity
If the bicycle lock is accommodated in a fixed pocket or bearing shell, then the structure is simple, but manufacturing tolerances cause play and shaking noises
Solution Approach 1:
The support element is designed with specific geometric parameters including extension length and cross-sectional shape that optimize the fit between the support element and the bicycle lock, minimizing play while maintaining structural simplicity
Solution Approach 2:
The support element features an asymmetric cross-section that provides optimal contact surfaces for different lock geometries, reducing play and vibrations while keeping the overall structure simple

AI summary
A bracket for a folding-type bicycle lock comprises a support (21) that defines a receiving area (29) for receiving the bicycle lock, and a fixing element (33) mounted on the support (21) and movable between an open and a closed position for securing the bicycle lock in the receiving area (29). A support element (31) is provided on the support (21), which projects from the support (21) along a transverse axis oriented perpendicular to the longitudinal axis and is designed to engage in a recess of the bicycle lock.The support element (31) is the only element of the holder which, in the open position of the fixing element (33), supports the two-wheel lock received in the receiving area (29) against movement along the longitudinal axis of the carrier (21), wherein, in the closed position, the fixing element (33) blocks the two-wheel lock against removal from the support element (31) along the transverse axis.
