Anti-skid Chain Link with Oval Cross-section
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional anti-skid chains face issues such as shear action leading to tire damage, reduced grip due to skewing of chain links, and increased wear, particularly in square and round link chains, which compromise traction and longevity.
Innovation Solution
A chain link design featuring a half-round outer cross-sectional area and an angular inner cross-sectional area, with optional chamfered or flat sides, and wear elements like pins or spikes, ensures optimal contact with the roadway, reducing shear and enhancing traction and longevity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If round link chains are used, then tire damage is reduced, but chain link stability and gripping action deteriorate due to skewing under load
Solution Approach 1:
The chain link employs different cross-sectional shapes at different locations: a round outer cross-section at the contact points with the tire to prevent damage, and a square inner cross-section in the body of the link to provide stability and prevent skewing under load. This local differentiation allows each region to optimize its properties for its specific function.
2Stability of the object's composition
If square link chains are used, then chain link stability improves, but tire damage increases due to shear action
Solution Approach 1:
The chain link employs different cross-sectional shapes at different locations: a round outer cross-section at the contact points with the tire to prevent damage, and a square inner cross-section in the body of the link to provide stability and prevent skewing under load. This local differentiation allows each region to optimize its properties for its specific function.
3Force
If special square chains with angular outer profile and round inner profile are used, then gripping action improves, but chain link flexibility increases causing skewing and tire damage
Solution Approach 1:
The chain link employs different cross-sectional shapes at different locations: a round outer cross-section at the contact points with the tire to prevent damage, and a square inner cross-section in the body of the link to provide stability and prevent skewing under load. This local differentiation allows each region to optimize its properties for its specific function.
4Stability of the object's composition
If square chains with angular inner profile are used, then chain link stability improves, but high forces occur between chain links causing tire damage
Solution Approach 1:
The chain link employs different cross-sectional shapes at different locations: a round outer cross-section at the contact points with the tire to prevent damage, and a square inner cross-section in the body of the link to provide stability and prevent skewing under load. This local differentiation allows each region to optimize its properties for its specific function.
