Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a UAV is used to cover large fishing areas, then the coverage area increases, but the precision of locating fish concentrations and deploying fishhooks deteriorates
Solution Approach 1:
The system segments the large fishing area into multiple zones by dividing it into a grid of latitude and longitude coordinates. The sonar unit systematically scans each zone sequentially, transforming one large area problem into multiple manageable small area detections, thereby maintaining detection precision across extensive coverage areas
Solution Approach 2:
The sonar unit acts as an intermediary between the UAV and the fish concentrations. It emits acoustic signals that reflect off fish schools and returns echolocation data to the processor, enabling indirect but precise detection of fish locations without direct visual observation, thus maintaining precision over large distances and areas
2Device complexity
If manual deployment of fishhooks is used, then the device complexity is low, but the deployment efficiency and accuracy deteriorate
Solution Approach 1:
The system performs self-service through automated operations: the processor automatically processes sonar data to identify fish concentrations, calculates optimal fishhook deployment coordinates, and controls the releasing mechanism without human intervention. This automation dramatically improves deployment efficiency while the modular design keeps complexity manageable
Solution Approach 2:
The manual mechanical deployment process is replaced with an automated electromechanical system. The processor sends electronic control signals to the releasing mechanism, which uses a solenoid or motor-driven latch to release the fishhook at the precise moment and location, substituting human manual operation with automated control for higher efficiency and accuracy
3Device complexity
If the sonar unit is fixed to the housing, then the device complexity is low, but the positioning precision and adaptability deteriorate
Solution Approach 1:
The sonar unit transitions from a fixed static position to a dynamic adjustable position. The positioning unit with motorized winch allows the sonar to be deployed to various depths and repositioned as needed, enabling adaptive optimization of detection precision for different fishing conditions while maintaining manageable system complexity through modular design
