Thermoplastic Wheel Chock Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wheel chock supporting and locking systems for vehicles are cumbersome, prone to component loss during disassembly, and suffer from rotational instability and corrosion, requiring multiple elements and time-consuming assembly/disassembly processes.
Innovation Solution
A single-piece thermoplastic wheel chock system with an elongated element and integrated locking mechanism, featuring a rotatable locking member and longitudinal projection, allows for secure attachment and easy removal without disassembly, enhancing stability and corrosion resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple elements (rings, pins, cotter pins) are used to fix the wheel chock to the chassis, then the locking function is achieved, but the assembly and disassembly process becomes time-consuming and complex
Solution Approach 1:
The patent combines multiple separate fixing elements (rings, pins, cotter pins) into a single integrated support structure. The support comprises a body with a receiving cavity and an integrated locking mechanism that includes a piston and spring assembly, eliminating the need for multiple discrete components and simplifying the assembly/disassembly process to a single operation.
2Reliability
If multiple separate elements are used for fixing, then the locking function is achieved, but the risk of losing elements increases during disassembly
Solution Approach 1:
The patent integrates all locking功能的 components within a single support structure. The piston, spring, and locking features are all contained within the support body, eliminating loose elements that could be lost during handling and disassembly.
Solution Approach 2:
The spring-loaded piston automatically returns to its original position after locking, and the support elements remain contained within the support structure throughout the operation, eliminating the need for manual storage and reducing the risk of loss.
3Ease of operation
If a circular metal support is used, then the wheel chock can be attached, but the wheel chock rotates and oscillates during vehicle motion
Solution Approach 1:
The support body features an asymmetric T-shaped cross-section with a vertical web and horizontal flanges, creating a non-circular geometry that prevents rotation. The locking mechanism uses asymmetric positioning of the piston and locking surfaces to maintain a fixed orientation of the wheel chock relative to the support.
