Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional tillage operations are performed without real-time residue length monitoring, then the operation speed and simplicity are maintained, but the residue piece lengths cannot be controlled to the desired specification, affecting soil productivity
Solution Approach 1:
The imaging device captures images of residue pieces before the tillage operation processes them. The computing system analyzes these images to determine residue length parameters in advance, allowing the system to pre-determine the optimal travel direction adjustments needed to achieve desired residue lengths, rather than reacting after the fact
Solution Approach 2:
The system continuously monitors residue piece lengths using the imaging device and computing system, then feeds this information back by automatically adjusting the travel direction of the agricultural implement. This closed-loop feedback ensures residue lengths are controlled to specification while the system handles the complexity of measurement and adjustment automatically
2Manufacturing precision
If the agricultural implement operates at constant speed without adaptive control, then the operational simplicity is maintained, but the residue length uniformity cannot be optimized across different field conditions
Solution Approach 1:
The system performs self-service by automatically detecting residue lengths, analyzing the data, and adjusting the implement's travel direction without operator intervention. The imaging device and computing system work autonomously to maintain residue length uniformity, freeing the operator from manual adjustments while ensuring consistent results across varying field conditions
3Measurement precision
If real-time imaging and analysis systems are implemented, then residue length measurement precision is improved, but the system complexity and cost increase
Solution Approach 1:
The system replaces manual mechanical measurement methods with optical imaging and computational analysis. The imaging device captures visual data of residue pieces, and the computing system automatically analyzes this data to determine lengths, providing precise measurements without the complexity of manual measurement tools and human operation
Solution Approach 2:
The imaging device creates optical copies (images) of the residue pieces, which the computing system then analyzes to determine length parameters. This copying approach allows for non-contact, rapid measurement of multiple residue pieces simultaneously, achieving high measurement precision while keeping the physical measurement system simple
