Solution Overview

Problem

Existing tire chain systems are cumbersome to install and remove, require specific tire sizes, are expensive, and often result in damage if not properly secured or removed, with limited adaptability for different road conditions.

Innovation Solution

A device permanently secured to the vehicle wheel assembly with independently moving friction grips that transition from an inactive to active position over the tire, allowing easy installation and removal, adaptability to various tire sizes, and reduced maintenance costs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Force

If conventional tire chains are used to increase friction on slippery roads, then traction is improved, but the device becomes heavy and difficult to install and remove

Engineering Contradiction:
ImprovefrictionVSAvoiddevice weight
Core Design Contradiction:
ForceVSWeight of moving object

Solution Approach 1:

The device divides the tire circumference into multiple independent segments, each with its own friction element. These segments can be independently installed and removed, reducing the overall weight that must be handled during installation while providing distributed friction enhancement across the tire surface.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The friction elements are designed to be dynamically deployable, transitioning from a stored configuration to an active friction-providing configuration. This allows the device to provide full friction capability only when needed, reducing the effective weight during normal operation while maintaining high friction availability when deployed.

Inventive Principle:
Principle #15Dynamics

2Force

If conventional tire chains are tightly secured to the tire, then friction is improved, but the installation process becomes complicated and time-consuming

Engineering Contradiction:
ImprovefrictionVSAvoidinstallation time
Core Design Contradiction:
ForceVSLoss of time

Solution Approach 1:

By segmenting the tire chain into independent units that can be installed separately, the overall installation process is broken down into simpler, faster steps. Each segment can be quickly attached without requiring the entire system to be installed sequentially, significantly reducing total installation time while maintaining secure attachment of each friction element.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The friction elements are pre-configured and pre-positioned in a manner that allows for rapid deployment. The segments are designed with pre-attached connection mechanisms that align with corresponding mounting points on the tire, eliminating the need for complex adjustment and securing operations during installation.

Inventive Principle:
Principle #10Preliminary action

3Force

If conventional tire chains are designed for specific tire sizes, then friction performance is optimized, but the device loses adaptability to different tires

Engineering Contradiction:
ImprovefrictionVSAvoidtire size compatibility
Core Design Contradiction:
ForceVSAdaptability or versatility

Solution Approach 1:

The device employs universal mounting mechanisms and standardized connection interfaces that can accommodate multiple tire sizes and types. The segmented design allows the same friction element to be installed on various tire configurations, providing optimized friction performance across different tire dimensions without requiring size-specific chain designs.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The device incorporates adjustable parameters such as segment spacing, friction element length, and mounting position that can be modified to match different tire sizes and conditions. This allows the same basic device to be optimized for various tire configurations while maintaining consistent friction enhancement performance.

Inventive Principle:
Principle #35Parameter changes

4Loss of time

If conventional tire chains are left on the road after use, then the driver avoids stopping to retrieve them, but this creates harmful effects on the road surface and environment

Engineering Contradiction:
Improveretrieval timeVSAvoidroad damage
Core Design Contradiction:
Loss of timeVSObject-generated harmful factors

Solution Approach 1:

The device is designed to be self-contained and permanently mounted on the vehicle, eliminating the need for drivers to retrieve chains from the road surface. The segments are securely attached to the tire and remain in place during normal operation, automatically returning to the vehicle when not in use without requiring driver intervention or creating road hazards.

Inventive Principle:
Principle #25Self-service
