Lateral Fixation Traction Device for Snowy Tire Grip
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing traction assistance devices for vehicles are cumbersome to assemble and disassemble, offer limited traction efficiency, and are not adaptable to all types of tires, especially on snowy ground, and recent vehicles with limited wheel well space.
Innovation Solution
A traction assistance device featuring a traction strip with polyurethane chain support blocks and lateral fixing modules, including sculpted grooves and saw teeth for enhanced traction and stability, allowing easy installation and removal by lateral attachment to the rim, which simplifies assembly and disassembly and improves traction performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional snow chains are used to improve traction efficiency, then traction performance is improved, but assembly and disassembly operations become tedious and time-consuming
Solution Approach 1:
The traction device is divided into modular components: a flexible support element that can wrap around the tire and separate chain sections that can be independently positioned and attached. This segmentation allows for easier assembly and disassembly while maintaining effective traction coverage.
Solution Approach 2:
The support element is designed to be flexible and adaptable, allowing it to dynamically conform to different tire sizes and shapes. This dynamic characteristic simplifies the assembly process by eliminating the need for precise fitting adjustments, thereby improving ease of operation while maintaining reliable traction.
2Ease of operation
If reinforced elastic fabric or textile wiring devices are used to simplify assembly and disassembly operations, then ease of operation is improved, but traction efficiency remains limited
Solution Approach 1:
The device combines a flexible support element (providing ease of operation) with rigid chain sections (providing high traction efficiency). This composite structure integrates the advantages of both materials: the flexibility and ease of installation from the fabric-like support and the superior grip from the metal chains, thereby resolving the contradiction between ease of operation and traction efficiency.
3Ease of operation
If lateral attachment to the rim is implemented to improve ease of operation, then assembly and disassembly become easier, but device complexity increases
Solution Approach 1:
The lateral attachment mechanism is extracted as a separate, simple component that attaches to the rim independently from the main chain structure. This extraction simplifies the overall device complexity by creating a distinct, easy-to-install attachment system that does not complicate the chain assembly itself, thereby maintaining ease of operation without excessive complexity.
