Secure Locking Hub System Retrofit Axle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle wheel hub locking systems require modification of the vehicle axle, making them impractical for retrofitting on existing vehicles and unable to secure non-motorized vehicles, while existing hitch coupler locks are vulnerable to theft due to exposed locks and lack of compatibility with various vehicle types.
Innovation Solution
A secure locking hub system that can be retrofitted to existing vehicle axles without modification, featuring a fastener with splines for rotational locking, a locking ring that moves axially between locked and unlocked configurations, and a mechanical actuator with a dial and lock to prevent unauthorized unlocking, ensuring the wheel hub remains locked in place.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a wheel hub locking system is designed to require axle modification, then the locking mechanism can be securely integrated, but the system becomes impractical for retrofitting on existing vehicles and requires costly manufacturing changes
Solution Approach 1:
The locking system is divided into separate modular components: a locking ring that interfaces with the existing axle, a hub assembly with integrated locking features, and a control mechanism. This segmentation allows the system to be installed on existing axles without modification while maintaining secure locking capability through the interface between the locking ring and axle splines or keyways.
Solution Approach 2:
The locking system is designed to be universally compatible with various existing axle types through standardized interface features. The locking ring can accommodate different axle configurations (spline patterns, keyway arrangements) without requiring axle modification, enabling retrofit installation on diverse vehicle platforms while providing the same secure locking function.
2Ease of manufacture
If an exposed padlock is used in a coupler lock system, then the locking function is simple and cost-effective, but the lock can be easily cut by lock cutters or otherwise compromised
Solution Approach 1:
A locking ring serves as an intermediary component between the coupler and the secure locking mechanism. This locking ring features a non-exposed, concealed locking interface that cannot be easily accessed or compromised by external tools like lock cutters, while still providing the necessary locking function through its engagement with the coupler and secure anchor points.
Solution Approach 2:
The system replaces traditional exposed mechanical padlocks with an integrated locking mechanism that uses internal mechanical interlocking features (splines, keyways, cam locks) concealed within the locking ring structure. This substitution eliminates the vulnerability of exposed external locks while maintaining mechanical reliability.
3Ease of manufacture
If a coupler lock system is designed for trailers only, then the locking mechanism can be optimized for trailer couplers, but it cannot be used to prevent theft of motorized vehicles
Solution Approach 1:
The locking hub system incorporates universal interface features that allow it to be adapted to both trailer axles and motorized vehicle axles. The locking ring design can accommodate different axle types (trailer ball hitches, motorized vehicle wheel hubs) through standardized mounting interfaces, enabling the same basic system to prevent theft across multiple vehicle categories.
Solution Approach 2:
The locking system includes adjustable and reconfigurable components that can adapt to different vehicle types. The locking ring can be positioned and configured to work with various axle configurations, and the system can be easily installed or removed depending on whether it's being used on a trailer or a motorized vehicle, providing dynamic versatility.

AI summary
A secure locking hub system for locking a wheel hub of a vehicle in a rotationally fixed position relative to an axle is provided. The system has a locking ring that may be moved between locked and unlocked configurations. When in the locked configuration, the wheel hub will not rotate and the vehicle thus cannot be moved. The system additionally has a security lock that prevents any unauthorized individual from unlocking the wheel hub, thereby preventing theft of the vehicle. The system includes a fastener designed to allow the system to be retrofitted to an existing vehicle axle without requiring replacement or mechanical modification of the axle.
