Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If tire pressure is adjusted manually for different operational states, then tire pressure can be optimized for specific conditions, but the process is time-consuming and increases downtime
Solution Approach 1:
The system dynamically adjusts tire pressure automatically based on real-time operational state detection. The processor monitors operational parameters and triggers the gas system to modify tire pressure without manual intervention, enabling the system to adapt to changing conditions while minimizing downtime between operational states.
Solution Approach 2:
The agricultural vehicle performs self-adjustment of tire pressure through an automated system. The processor detects operational state changes and automatically controls the gas system to inflate or deflate tires as needed, eliminating the need for manual pressure adjustment and reducing operator involvement.
2Strength
If tire pressure is increased for high-load conditions, then load-bearing capacity improves, but mobility and traction decrease on soft surfaces
Solution Approach 1:
The system dynamically adjusts tire pressure based on the detected operational state and loading conditions. When transitioning from high-load to low-load operations, or when mobility is prioritized, the gas system reduces tire pressure to improve contact with the ground and reduce rolling resistance, thereby enhancing mobility without compromising load-bearing capacity when needed.
Solution Approach 2:
The system changes the physical parameter of tire pressure to optimize performance for different operational conditions. By adjusting pressure levels according to detected operational states, the system achieves optimal balance between load-bearing capacity and mobility for each specific working condition.
3Ease of operation
If tire pressure is decreased for low-load conditions, then mobility improves, but tire wear increases due to excessive flexing
Solution Approach 1:
The system dynamically monitors operational state and automatically adjusts tire pressure to maintain optimal levels. When the vehicle transitions from low-load to high-load operations, or when stability is required, the gas system increases tire pressure to reduce excessive flexing and minimize tire wear, while maintaining mobility benefits when appropriate.
Solution Approach 2:
The processor continuously monitors operational state and provides feedback control for tire pressure adjustment. This closed-loop system ensures tire pressure is maintained within optimal ranges by detecting operational conditions and triggering appropriate pressure adjustments, thereby preventing excessive tire flexing and wear while preserving mobility advantages.
4Productivity
If manual tire pressure adjustment is performed, then operational efficiency can be optimized, but labor requirements and operational complexity increase
Solution Approach 1:
The agricultural vehicle automatically manages tire pressure adjustment through an integrated system comprising load sensors, a processor, and a gas system. The processor detects operational state changes and autonomously controls pressure adjustment without requiring operator intervention, thereby maintaining productivity benefits while eliminating the complexity of manual adjustment procedures.
Solution Approach 2:
The system replaces manual mechanical adjustment with an automated electromechanical system. The processor electronically detects operational states and controls the gas system to automatically adjust tire pressure, substituting manual labor and simplifying the operational process while maintaining or improving productivity.
