Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the puller wheels are fixed in position, then the structure is simple and stable, but the gap cannot be adjusted for different beet sizes
Solution Approach 1:
The patent applies the dynamics principle by making the previously fixed wheel positioning adjustable. The wheel gap can now be dynamically changed to adapt to different beet sizes, transforming a static structure into a dynamic one that responds to varying operational requirements.
Solution Approach 2:
The patent implements parameter changes by modifying the gap distance between puller wheels from a fixed parameter to an adjustable one. This allows the operational parameter (gap size) to be changed based on the specific requirements of different crop sizes, improving adaptability without fundamentally redesigning the entire system.
2Ease of operation
If the gap adjustment method involves unbolting wheels and inserting spacers, then the structure remains simple, but the adjustment process becomes time-consuming and complicated
Solution Approach 1:
The adjustment mechanism is made dynamic and movable, allowing the wheels to be repositioned along the axle without complete disassembly. This transforms a static, time-consuming manual adjustment process into a more flexible and quicker operation.
Solution Approach 2:
The adjustment system is segmented into movable components that can be independently repositioned. By dividing the wheel-axle connection into separable yet quickly reconnectable segments, the system enables rapid adjustment without requiring complete unbolting and reassembly of the entire wheel assembly.
3Adaptability or versatility
If the puller wheels are too far apart, then larger beets can be harvested, but smaller beets may not be effectively pulled from the ground
Solution Approach 1:
The gap parameter between puller wheels is made variable to match the size parameter of different beets. This allows the system to optimize the gap distance according to the specific crop size, ensuring effective harvesting across varying beet dimensions without sacrificing productivity for any size category.
Solution Approach 2:
The wheel positioning system becomes dynamic, allowing operators to adjust the gap in real-time based on the beet size being harvested. This dynamic adaptation ensures that the harvesting mechanism remains effective regardless of variations in crop size, maintaining high productivity across different harvesting conditions.
4Productivity
If the puller wheels are too close together, then smaller beets can be effectively harvested, but the wheels will damage the crop and reduce yield
Solution Approach 1:
The gap parameter is made adjustable to prevent harmful effects. By increasing the gap distance when harvesting smaller beets, the system avoids the damaging effect of wheels being too close together, thus eliminating crop damage while maintaining harvesting effectiveness for small beets.
