Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the pump motor and nozzle motor maintain constant rotational speed, then the device operation is simple and stable, but the pesticide spraying uniformity deteriorates due to flight speed variations and external disturbances
Solution Approach 1:
The patent implements dynamic speed adjustment of the pump motor and nozzle motor based on real-time flight speed detection. The control system continuously monitors flight speed and adjusts motor rotational speeds accordingly, transitioning from static constant-speed operation to dynamic variable-speed operation to maintain spraying uniformity under varying flight conditions
Solution Approach 2:
The patent employs a feedback control mechanism where the microcontroller receives flight speed information from sensors, processes this data, and adjusts the pump motor and nozzle motor speeds accordingly. This closed-loop feedback system ensures that spraying parameters are continuously optimized based on actual flight conditions, resolving the contradiction between operational simplicity and spraying uniformity
2Adaptability or versatility
If the aircraft accelerates or decelerates during spraying, then the flight adaptability is improved, but the pesticide spraying uniformity deteriorates due to speed changes
Solution Approach 1:
The system dynamically adjusts the rotational speeds of the pump motor and nozzle motor in real-time based on detected flight speed changes. When the aircraft accelerates or decelerates, the control system modifies motor speeds to compensate, maintaining consistent pesticide delivery rates despite flight speed variations, thus preserving spraying precision while enabling flight adaptability
Solution Approach 2:
The patent changes the operational parameters (rotational speeds) of the pump motor and nozzle motor based on flight conditions. By adjusting these parameters in response to flight speed changes, the system maintains optimal spraying performance across varying flight speeds, resolving the conflict between flight adaptability and spraying precision
