Segmented Anti-Theft Jaw Locking Mechanism for Motorcycle Wheel Immobilization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing anti-theft devices for vehicles are bulky, difficult to store, and vulnerable to break-ins, as they cannot be positioned close to the vehicle's frame or wheels, and often require additional locking components that can be easily split.
Innovation Solution
A removable anti-theft device comprising two distinct parts that assemble around the vehicle's wheel, with a J-shaped and C-shaped locking jaw integrated with a locking block for secure positioning and compact storage, featuring a locking mechanism with a movable locking member and interlocking zones for enhanced security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional rigid U-shaped locks or chain locks are used, then the vehicle can be immobilized, but the device becomes bulky and difficult to store in the vehicle
Solution Approach 1:
The anti-theft device is divided into two separate parts: a first part with a first locking jaw and a second part with a second locking jaw. These parts can be stored separately in the vehicle and assembled when needed, reducing storage volume while maintaining immobilization effectiveness
Solution Approach 2:
The two locking jaws are designed to nest together when assembled, with the first locking jaw fitting within or alongside the second locking jaw, creating a compact integrated structure that minimizes storage space when not in use
2Ease of operation
If traditional anti-theft devices are positioned away from the wheel, then they are easier to install, but they become vulnerable to break-in attempts with shear clips
Solution Approach 1:
The locking jaws are pre-configured with receiving zones and interlocking profiles that are designed to engage with the wheel rim and each other in a specific sequence, allowing the device to be positioned intimately around the wheel for maximum security while maintaining straightforward installation through predetermined engagement points
Solution Approach 2:
The locking jaws feature specific localized features such as profiled interlocking zones and complementary receiving zones at critical positions, concentrating security features where they are most needed to prevent break-in while keeping the overall design simple
3Reliability
If additional separate locking blocks are used to secure the anti-theft device, then the wheel can be immobilized, but the device complexity increases and the locking block can be easily split
Solution Approach 1:
The locking function is integrated directly into the assembly end pieces of the locking jaws themselves, rather than requiring a separate locking block. The first assembly end piece and second assembly end piece incorporate locking mechanisms that engage with each other, reducing component count and eliminating the vulnerability of separate padlocks
Solution Approach 2:
The assembly end pieces serve multiple functions: they connect the two locking jaws together, provide the locking mechanism, and interface with the wheel rim. This multi-functionality reduces the need for separate components while maintaining secure immobilization

AI summary
The present invention relates to a removable anti-theft device (1) for blocking at least one wheel of a vehicle. It comprises two separate parts: a blocking jaw (2) and a locking jaw (3) equipped with a locking block (4). Each of the two jaws (2, 3) has a free, hook-shaped end (20, 30) arranged to hook onto a part or into an opening in the vehicle located on either side of the wheel. They are then joined by their connecting end (22, 32) through the wheel rim and subsequently locked by the locking block (4), rendering this anti-theft device tamper-proof as it is located as close as possible to the wheel.
