Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If residue coverage is estimated based on crop yield alone, then the estimation process is simple, but the accuracy of residue coverage determination deteriorates due to uneven residue distribution
Solution Approach 1:
The patent combines yield data from yield sensors with actual residue measurements from residue sensors to create a comprehensive residue coverage map. This merging of multiple data sources resolves the contradiction by maintaining measurement accuracy while providing a more robust estimation process that accounts for uneven residue distribution
Solution Approach 2:
The system uses residue sensors to provide feedback on actual residue distribution, which then corrects and refines the initial yield-based estimates. This feedback mechanism ensures accurate residue coverage determination while maintaining a relatively simple operational process
2Device complexity
If uniform residue distribution is assumed across the field, then the mapping process is simplified, but the accuracy of residue coverage data deteriorates
Solution Approach 1:
The patent implements local quality by allowing residue coverage to vary spatially across different locations in the field. The residue coverage map stores location-specific residue data rather than assuming uniform distribution, enabling accurate representation of uneven residue patterns while maintaining practical mapping operations
Solution Approach 2:
The field is divided into multiple discrete locations or zones, each with its own measured residue coverage data. This segmentation allows the system to capture local variations in residue distribution without requiring overly complex continuous mapping procedures

AI summary
A method for determining residue coverage within a field after a harvesting operation may include receiving yield data associated with an estimated crop yield across a field and generating an estimated residue coverage map for the field based at least in part on the yield data. The method may further include receiving residue data associated with residue coverage across a surface of the field following the performance of a harvesting operation within the field. Additionally, the method may include generating an updated residue coverage map for the field based at least in part on the estimated residue coverage map and the residue data.
