Solution Overview

Problem

Existing tire chains are heavy, difficult to handle, and lack sufficient traction force, especially on dry surfaces, posing safety risks and requiring frequent mounting and dismounting based on weather conditions.

Innovation Solution

A lightweight tire device with thin line structures encircling the tire's sidewalls, connected by cross members with straps and traction components featuring raised structures and studs, designed for easy installation and use on various surfaces, including snow, ice, and bare roads, with adjustable patterns and materials like nylon and polyester for enhanced traction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Force

If metal tire chains are used, then sufficient traction force is achieved, but the device becomes heavy and difficult to handle

Engineering Contradiction:
Improvetraction forceVSAvoidweight
Core Design Contradiction:
ForceVSWeight of moving object

Solution Approach 1:

The patent combines metal studs embedded in rubber traction components, creating a composite structure that provides the traction force of metal with the lightweight and flexible properties of rubber. This resolves the contradiction by integrating materials with complementary properties to simultaneously achieve both high force and low weight.

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

The patent applies metal studs only at specific contact points where traction is needed, rather than making the entire chain from metal. The rubber portions provide structural support and flexibility while the localized metal studs provide the necessary gripping force, optimizing the weight-to-traction ratio.

Inventive Principle:
Principle #3Local quality

2Force

If metal tire chains are used, then sufficient traction force is achieved, but the device complexity and difficulty of mounting increases

Engineering Contradiction:
Improvetraction forceVSAvoidmounting complexity
Core Design Contradiction:
ForceVSDevice complexity

Solution Approach 1:

The patent uses flexible rubber straps instead of rigid metal links, allowing the traction device to conform to the tire contour and be more easily mounted. The flexibility of the rubber material simplifies the mounting process while the embedded metal studs maintain the necessary traction force.

Inventive Principle:
Principle #30Flexible shells and thin films

3Weight of moving object

If textile belt is used, then light-weight and ease of handling is achieved, but insufficient traction force is provided

Engineering Contradiction:
ImproveweightVSAvoidtraction force
Core Design Contradiction:
Weight of moving objectVSForce

Solution Approach 1:

The patent combines rubber material with embedded metal studs, creating a composite traction component that provides both the lightweight property of non-metal materials and the high traction force of metal. This resolves the contradiction by integrating materials with complementary properties.

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

The patent concentrates metal studs at the contact surfaces where traction is generated, while the bulk of the structure uses lighter rubber material. This localized application of metal provides sufficient traction force while maintaining overall light weight.

Inventive Principle:
Principle #3Local quality

4Adaptability or versatility

If tire chains are mounted and dismounted frequently, then adaptability to weather conditions is improved, but loss of time and ease of operation deteriorates

Engineering Contradiction:
Improveadaptability to weather conditionsVSAvoidmounting and dismounting time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The flexible rubber construction allows the traction device to be quickly adjusted and mounted without the complex fastening procedures required by rigid metal chains. The elasticity and conformability of rubber enable faster installation while maintaining adaptability to different tire sizes and weather conditions.

Inventive Principle:
Principle #30Flexible shells and thin films
