Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If radar sensors are used to scan the sub-surface detection zone before and after seed deposition, then seed placement accuracy is improved, but device complexity increases
Solution Approach 1:
The detection zone is segmented into multiple cells arranged in a matrix pattern, with radar data points organized into corresponding cells before and after seed deposition. This segmentation enables precise localization of seed placement by comparing radar reflections across discrete spatial units, improving measurement precision while maintaining manageable system complexity through structured data organization.
Solution Approach 2:
The first radar sensor scans the sub-surface detection zone before seed deposition to establish a baseline radar reflection profile. This preliminary scanning creates reference data that is later compared with post-deposition radar scans to detect seed placement location and depth, enabling accurate measurement without requiring complex real-time processing during the actual planting operation.
2Measurement precision
If multiple radar sensors scan the sub-surface detection zone before and after seed deposition, then seed placement accuracy is improved, but loss of time increases
Solution Approach 1:
The radar sensors perform scanning operations in periodic cycles: first scanning before seed deposition, then scanning after seed deposition. This periodic scanning approach allows the system to capture radar reflection changes caused by seed placement without requiring continuous scanning, reducing time loss while maintaining accurate detection through the before-after comparison method.
Solution Approach 2:
The baseline radar scan is performed beforehand to establish reference data, allowing the actual seed placement detection to be performed more efficiently by only processing changes from the pre-established baseline rather than processing all radar data in real-time during the planting operation.
3Measurement precision
If radar data matrices are generated and processed to determine seed location, then seed placement accuracy is improved, but use of energy increases
Solution Approach 1:
The radar data is segmented and organized into matrices corresponding to discrete detection cells in the sub-surface detection zone. This segmentation allows the system to process only the relevant radar data points within each cell rather than processing the entire radar dataset, reducing energy consumption while maintaining precise seed location determination through focused analysis of critical data regions.
