Spring Tire Tread Structure for Sand Intrusion Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Tires with coil springs suffer from performance deterioration due to sand entering gaps between the springs, causing abnormalities in the drive mechanism, especially on sandy ground, leading to reduced driving force.
Innovation Solution
A tire design featuring a skeleton portion with rim members, body springs, and interlink springs that are interlaced and securely latched, along with a tread member on the outer periphery to prevent foreign matter from entering and maintain performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If coil springs are used to form the tire structure, then the tire achieves flexibility and cushioning performance, but sand enters the gaps between springs causing drive mechanism abnormalities and performance deterioration
Solution Approach 1:
A tread member is introduced as an intermediary component between the external environment (sand) and the coil spring structure. This tread member acts as a protective barrier that prevents sand from entering the gaps between springs, thereby maintaining drive mechanism reliability while preserving the structural flexibility provided by the coil springs.
2Duration of action of moving object
If coil springs are interlaced to form the tire body, then the tire achieves elastic deformation capability, but gaps between springs allow sand entry leading to reduced driving force
Solution Approach 1:
The tread member serves as a protective intermediary that maintains the elastic deformation capability of the coil springs by preventing sand contamination. By blocking sand from entering the spring gaps, the tread member ensures that the springs can continue to deform elastically without the power loss caused by sand interference.
3Reliability
If a tread member is added to cover the outer periphery of the skeleton portion, then protection against foreign matter entry is improved, but device complexity increases
Solution Approach 1:
The tread member is implemented as a flexible covering layer that conforms to the outer periphery of the skeleton portion. This thin film-like structure provides effective protection against foreign matter entry while adding minimal structural complexity, as it simply covers the existing spring structure without requiring complex mechanical components.
