Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-generated harmful factors
If rubber or elastomeric track assemblies are used, then vibration absorption and quiet operation are improved, but mechanical strength and resistance to damage are reduced
Solution Approach 1:
The track assembly uses a composite structure combining a rigid steel C-shaped member providing mechanical strength with an elastomeric coating providing vibration absorption and noise reduction. This composite material approach resolves the contradiction by integrating both strong and damping materials in a single functional component.
2Reliability
If metallic tyre chains are used, then traction and flotation are improved, but noise levels and damage to paved roads increase
Solution Approach 1:
The invention combines rigid steel structural members for traction with elastomeric coating material that reduces noise and prevents road damage. The elastomeric outer surface contacts the ground while the steel C-shaped member provides structural integrity and engagement forces, resolving the contradiction between effective traction and harmful noise/road damage.
3Area of stationary object
If conventional tyre chains are used, then contact area and flotation are improved, but maintenance complexity and manufacturing cost increase
Solution Approach 1:
The invention merges the structural C-shaped member and the elastomeric coating into a single integrated track element, eliminating the need for separate components that require complex assembly and maintenance. The elastomeric coating is applied directly to the steel member, creating a unified structure that simplifies both manufacturing and maintenance while maintaining large contact area for flotation.
4Ease of operation
If rubber track assemblies are used, then ease of operation is improved, but mechanical strength and durability are reduced
Solution Approach 1:
The track element combines elastomeric material providing ease of operation with steel C-shaped members providing mechanical strength. The elastomeric coating absorbs vibrations and provides quiet operation while the rigid steel structure maintains durability and resistance to mechanical failure, resolving the contradiction between ease of operation and mechanical strength.
