Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If automated optimization process is used for work parameters and quality parameters, then productivity and efficiency are improved, but the system fails to achieve satisfactory results when material properties deviate from expectations or terrain conditions are challenging
Solution Approach 1:
The system continuously monitors actual harvesting results and material properties, comparing them against target values. When deviations are detected (such as when material properties differ from expectations), the system provides feedback to the optimization process, enabling dynamic adjustment of work parameters to maintain reliable results under varying conditions
Solution Approach 2:
The optimization process transitions from static pre-defined performance maps to dynamic real-time optimization. The system continuously adapts work parameters based on current material properties and terrain conditions detected by sensors, allowing the optimization to remain reliable even when conditions deviate from normal expectations
2Ease of operation
If automated optimization runs without operator interaction, then ease of operation is improved, but the system cannot resolve conflicts when objectives are contradictory under unusual conditions
Solution Approach 1:
The system introduces an intermediary layer between automated optimization and operator control. The conflict detection and resolution module acts as a mediator that automatically handles routine conflicts but can escalate to operator intervention when complex judgment is needed, combining automated ease of operation with human adaptability for unusual conditions
Solution Approach 2:
The system performs preliminary automated conflict detection and resolution before operator intervention is needed. By continuously monitoring for objective conflicts and attempting automatic resolution through performance map adjustments, the system maintains ease of operation while preparing for potential operator involvement when automatic resolution fails
