Engineering Contradiction Analysis
1Ease of operation
If a plant identification model is configured by operator input, then the system is easy to operate, but the reliability of correct identification decreases due to human error
Solution Approach 1:
The system performs self-verification by automatically checking whether the plant identification model's configuration matches the actual field conditions. The farming machine independently detects plant types in the field and compares them with the model's expected targets, eliminating reliance on operator accuracy while maintaining ease of operation.
Solution Approach 2:
The system establishes a feedback loop where the plant identification model's performance is continuously monitored against actual field observations. When discrepancies are detected (e.g., model expects crop type A but field contains crop type B), the system generates feedback signals to alert operators and enable corrective action, thereby improving reliability without complicating the configuration process.
2Measurement precision
If multiple plant identification models are applied to verify plant class, then the measurement precision improves, but the device complexity increases
Solution Approach 1:
The verification process is segmented into distinct functional modules: (1) primary plant identification using the configured model, (2) field reality detection using image capture, (3) comparison logic that matches detected plants with model targets, and (4) discrepancy reporting. This segmentation manages complexity by organizing the multi-model verification into discrete, manageable steps rather than a monolithic complex system.
3Productivity
If real-time monitoring and automatic adjustment is implemented, then the productivity of farming operations improves, but the use of energy increases due to continuous processing
Solution Approach 1:
Instead of continuous real-time monitoring, the system implements periodic verification at strategically chosen intervals during field traversal. The plant identification model is applied to representative sample images captured at regular intervals or at transition points between field zones, maintaining productivity benefits while significantly reducing computational energy consumption compared to continuous processing of every image frame.

AI summary
A farming machine configured for identifying incorrectly configured plant identification models in farming machines is disclosed. The farming machine includes a control system configured to monitor the performance of a plant identification model to determine if it is appropriately configured for detecting plants in the field. To do so, the control system accesses images of plants in the field and applies a first plant identification model to the images to identify a probability that plants in the images are a first class of plants. The control system applies a verification model to determine if plants in the field are the second class of plants (rather than the first) based on the determined probability. The farming machine applies a second plant identification model to the images to identify a second class of plants and treats plants in the field identified as the second class of plant.
