Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If snow chains or auxiliary chains are installed on tracked vehicles, then traction and stability on slippery surfaces are improved, but device complexity increases

Engineering Contradiction:

Improvetraction and stabilityVSAvoiddevice complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The snow chain is divided into multiple individual links that can be independently attached to the track. Each link is a separate component that connects to adjacent links through coupling mechanisms, allowing the chain to be segmented into manageable sections while maintaining overall structural integrity and functionality.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Multiple snow chain links are combined to form a continuous chain structure that wraps around the track. The individual links are merged through coupling mechanisms to create a unified system that provides comprehensive traction coverage around the entire track perimeter.

Inventive Principle:

Principle #5Merging (Combining)

2Reliability

If a continuous snow chain is used around the track, then traction effectiveness is improved, but ease of installation deteriorates

Engineering Contradiction:

Improvetraction effectivenessVSAvoidease of installation

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The snow chain links are pre-assembled into continuous sections or pre-configured modules before installation on the track. This preliminary assembly allows for easier installation by reducing the number of separate components that need to be individually mounted, while still maintaining the continuous traction effect.

Inventive Principle:

Principle #10Preliminary action

3Reliability

If traditional snow chains are used, then traction is improved, but adaptability to different track types deteriorates

Engineering Contradiction:

ImprovetractionVSAvoidadaptability to different track types

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The snow chain links are designed with universal coupling mechanisms that can accommodate different track types and configurations. The links can be attached to various track materials and designs through standardized connection methods, making the snow chain system adaptable to different vehicle types and track configurations.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The snow chain links can be selectively designed or configured to match specific local requirements of different track sections. Different link designs can be used on different parts of the track where different traction characteristics are needed, allowing optimization for specific local conditions while maintaining overall system functionality.

Inventive Principle:

Principle #3Local quality
