Engineering Contradiction Analysis
1Productivity
If automated control systems use worksite maps or imagery to guide agricultural machines, then operational efficiency is improved, but work quality consistency deteriorates due to coverage gaps and incomplete field coverage
Solution Approach 1:
The system captures image data during agricultural operations, processes this data to identify coverage gaps and unharvested areas, and uses this feedback information to adjust machine settings and guidance for subsequent passes. This closed-loop feedback mechanism enables the system to maintain high productivity while improving work quality consistency by correcting coverage issues in real-time or near-real-time.
Solution Approach 2:
The system dynamically adjusts machine operating parameters such as header positioning, travel speed, and pass spacing based on actual field conditions observed in image data. This dynamic adaptation allows the system to maintain optimal productivity while ensuring consistent work quality across varying field conditions, soil types, and crop densities.
2Manufacturing precision
If machine settings are adjusted based on performance metrics from previous passes, then coverage gaps are reduced, but system complexity increases due to image processing and adaptive control requirements
Solution Approach 1:
The system performs self-diagnosis and self-adjustment by automatically processing its own operational data and image captures to identify coverage gaps. The machine autonomously determines optimal settings for subsequent passes without requiring external intervention, thereby reducing coverage gaps while managing complexity through automated decision-making algorithms.
Solution Approach 2:
The system replaces manual monitoring and adjustment mechanisms with automated image processing and electronic control systems. By substituting mechanical observation and manual adjustment with optical sensing and computational analysis, the system achieves improved coverage completeness while the complexity is managed through software-based solutions rather than additional mechanical components.
3Manufacturing precision
If in situ image data is captured and analyzed during operations, then work quality is enhanced through real-time feedback, but energy consumption increases due to imaging and processing requirements
Solution Approach 1:
The system captures image data at periodic intervals rather than continuously, processing images at strategic points during operational passes. This periodic sampling approach provides sufficient feedback for quality enhancement while significantly reducing energy consumption compared to continuous imaging and processing, maintaining an optimal balance between work quality and energy usage.

AI summary
A method of controlling a mobile agricultural machine that includes performing an agricultural operation during a given pass in a field using a first set of machine settings, obtaining in situ data representing the agricultural operation during the given pass, generating a performance metric based on the in situ data, identifying a second set of machine settings based on the performance metric, and outputting a control instruction that controls the mobile agricultural machine during a subsequent pass in the field based on the second set of machine settings.
