Solution Overview
Problem
Existing anti-skid devices for vehicle wheels require additional components and longer assembly times, which increases costs and complexity without adequately addressing stress and fatigue resistance.
Innovation Solution
An anti-skid device featuring a spider chain system with flexible connecting elements and a simplified support structure that integrates the connecting elements within the support, allowing for rapid assembly and enhanced resistance to fatigue through optimized component usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If brackets are used to constrain chain portions to supports, then the chain portions are retained in position and stresses are absorbed, but the number of components increases and assembly time increases
Solution Approach 1:
The patent merges the bracket function into the support structure itself. The support is designed with integration zones where chain portions are directly constrained without requiring separate bracket components. This combining of functions reduces the total number of components while maintaining the stress absorption capability through the unified support-bridge structure.
Solution Approach 2:
The support structure is designed to perform multiple functions: it provides structural support, constrains chain portions through integrated zones, and absorbs stresses. This multi-functional design eliminates the need for separate brackets, as the support itself becomes a universal component that handles both positioning and stress management.
2Reliability
If brackets are used to constrain chain portions to supports, then the chain portions are retained in position and stresses are absorbed, but the assembly time increases
Solution Approach 1:
By integrating the constraint function into the support structure, the assembly process is simplified. Instead of installing separate brackets onto supports and then attaching chain portions, the unified support with integrated constraint zones allows for direct installation, reducing assembly steps and time while maintaining reliable stress absorption.
Solution Approach 2:
The constraint zones are pre-integrated into the support structure during manufacturing. This preliminary action of incorporating the constraint mechanism into the support itself eliminates the need for additional assembly steps involving separate brackets, thereby reducing assembly time while ensuring proper stress absorption from the outset.
3Reliability
If additional components are added to the anti-skid device, then stress absorption is improved, but the cost increases
Solution Approach 1:
The patent combines multiple functions into the support structure, eliminating the need for separate bracket components. This reduction in component count directly lowers manufacturing costs through fewer parts to produce, inventory to manage, and assembly operations to perform, while the integrated constraint zones maintain effective stress absorption capability.
Solution Approach 2:
The multi-functional support structure that constrains chain portions and absorbs stresses eliminates the need for additional specialized components. This universality reduces the bill of materials and manufacturing complexity, leading to cost reduction while maintaining or improving stress absorption through the optimized unified structure.
