Adjustable Claw Brake Disc Lock for Secure Multi-Disc Fit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional brake disc locks require complex operation and may have excessive play, leading to an insecure fit on different brake discs, making them prone to unauthorized removal and tampering.
Innovation Solution
A brake disc lock with an adjustable claw that securely fits various brake discs by allowing one-handed operation and featuring an adjustment mechanism to set a predetermined clear width, ensuring a snug fit and preventing unauthorized removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the receiving slot depth is fixed, then the brake disc lock structure is simple, but the play between the brake disc lock and brake disc becomes excessively large
Solution Approach 1:
The receiving slot is designed with a movable bottom that can be adjusted axially relative to the claw. This dynamic structure allows the receiving slot to adapt its depth to match different brake disc thicknesses, eliminating excessive play while maintaining structural simplicity. The movable bottom is actuated by a spring mechanism that automatically positions the receiving slot at the optimal depth.
2Ease of operation
If the brake disc lock uses a conventional alignment procedure, then the operation process is straightforward, but two-handed operation is required which reduces ease of use
Solution Approach 1:
The brake disc lock incorporates a hook structure that automatically engages with the brake disc opening during insertion. This self-aligning mechanism eliminates the need for manual alignment procedures, allowing the lock to position itself correctly on the brake disc. The spring-loaded receiving slot bottom further assists by automatically adjusting to the correct position, enabling secure one-handed operation.
3Adaptability or versatility
If the claw clear width is not adjustable, then the brake disc lock structure is simple, but it cannot securely fit various brake discs of different sizes
Solution Approach 1:
The claw is designed with an adjustable clear width through a movable side wall that can be positioned at different locations. This dynamic adjustment capability allows the brake disc lock to accommodate various brake disc sizes and thicknesses. The adjustment is facilitated by the spring mechanism that moves the receiving slot bottom, which is coupled with the claw positioning system.

AI summary
A disc brake lock comprises a claw having a first claw section and a second claw section that are movable relative to each other between an open and a closed position, the claw having a predetermined opening in the closed position to engage a section of a two-wheeled brake disc. The disc brake lock further comprises a locking mechanism designed to lock the claw in the closed position and an adjustment device designed to adapt the predetermined opening of the claw to different brake discs.
