Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a single-stage bearing unit is used to support the tool element, then the device complexity is reduced, but the measurement precision deteriorates due to potential falsified measurement results under varying soil conditions
Solution Approach 1:
The bearing unit is divided into multiple stages, with each stage comprising bearing elements that support the tool element at different positions. This segmentation allows for more accurate force distribution measurement while maintaining manageable device complexity through modular construction
Solution Approach 2:
The multi-stage bearing unit acts as an intermediary structure between the tool element and the support unit, providing intermediate support points that enable more precise measurement of forces acting on the tool element during operation
2Adaptability or versatility
If the agricultural machine operates under varying soil conditions, then the adaptability is improved, but the measurement precision deteriorates due to changes in soil properties affecting force measurements
Solution Approach 1:
The bearing unit is designed with multiple stages that can dynamically respond to varying soil conditions, allowing the support structure to adapt to changing forces while maintaining measurement accuracy through distributed sensing points
Solution Approach 2:
The system measures changes in operating parameters (forces, positions) at multiple bearing stages to detect and adapt to varying soil conditions, using these parameter changes to maintain measurement precision despite external condition variations
