Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If stacked or free-floating rollers are used to follow terrain variations, then adaptability to terrain is improved, but ground coverage completeness deteriorates due to bridging and friction
Solution Approach 1:
The roller assembly is made dynamically adjustable through a mechanism that allows the roller axis position to be varied relative to the shaft. This enables the roller to adapt to terrain variations while maintaining consistent ground contact, resolving the contradiction between terrain adaptability and ground coverage completeness.
Solution Approach 2:
The invention changes the geometric parameters of the roller assembly, specifically the distance between the roller axis and shaft, to optimize both terrain following capability and ground contact. By adjusting this parameter, the system achieves reliable ground coverage across varying terrains without bridging.
2Adaptability or versatility
If friction between adjacent rollers is reduced to improve terrain following, then adaptability is improved, but power consumption increases due to increased friction with shaft and ground
Solution Approach 1:
The dynamic adjustment mechanism allows the roller assembly to optimize its configuration for terrain following while minimizing frictional losses. By enabling controlled movement and positioning, the system reduces unnecessary friction with the shaft and ground, thereby lowering power consumption while maintaining adaptability.
3Device complexity
If fixed weight rollers are used to simplify the system, then device complexity is reduced, but adaptability to different mine types deteriorates due to inability to vary pressure
Solution Approach 1:
The roller assembly incorporates a dynamic pressure adjustment mechanism that allows the force applied to the ground to be varied. This enables the same roller assembly to effectively detonate different types of land mines by adjusting the contact pressure, maintaining versatility without requiring multiple fixed-weight roller sets.
Solution Approach 2:
The roller assembly is designed as a universal component that can perform multiple functions by adjusting its pressure application. The same assembly can handle various mine types (anti-personnel, anti-tank, etc.) by modifying the force exerted on the ground, eliminating the need for specialized rollers for each mine category.
4Adaptability or versatility
If larger central opening diameter is used to accommodate terrain variation, then terrain adaptability is improved, but roller structural strength deteriorates
Solution Approach 1:
The invention uses a dynamic adjustment mechanism that allows the roller assembly to achieve the necessary terrain accommodation without requiring an excessively large central opening. By adjusting the roller axis position relative to the shaft, the system maintains both structural integrity and adaptability to terrain variations.
