Engineering Contradiction Analysis
1Object-affected harmful factors
If temperature inversion detection system is added to the sprayer, then substance drift prevention capability is improved, but device complexity increases
Solution Approach 1:
The detection system is divided into multiple temperature sensors positioned at different heights (first sensor at higher elevation, second sensor at lower elevation) that independently measure temperature at their respective locations. This segmentation allows the system to detect temperature inversion conditions through comparison of discrete sensor readings rather than requiring a single complex sensor.
Solution Approach 2:
The control system acts as an intermediary that receives temperature data from multiple sensors, compares the readings to determine if a temperature inversion is present, and generates appropriate output signals. This intermediary processing layer simplifies the overall system architecture by centralizing the detection logic rather than requiring complex integrated sensors.
2Reliability
If real-time temperature inversion detection is implemented, then spraying operation safety is improved, but loss of time in monitoring and processing increases
Solution Approach 1:
The system continuously monitors temperature conditions before spraying operations begin and maintains readiness to detect inversion conditions. By having sensors already in place and the control system pre-configured to analyze temperature data, the system eliminates delays that would occur if monitoring were initiated only when spraying started.
Solution Approach 2:
The control system continuously receives temperature data from sensors, compares readings to determine inversion conditions, and provides immediate output signals to the user interface. This closed-loop feedback mechanism ensures real-time detection and response without requiring manual intervention or delayed processing.
3Measurement precision
If multiple sensors at different elevations are used to detect temperature inversion, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The temperature monitoring function is segmented across multiple sensors positioned at different elevations (first sensor at higher elevation, second sensor at lower elevation). Each sensor independently measures temperature at its specific location, and the control system compares these segmented measurements to detect inversion conditions, improving measurement precision through spatial distribution.
Solution Approach 2:
The control system performs multiple functions using the same sensor inputs: it monitors temperature readings, compares elevational differences, detects inversion conditions, and generates output signals. This multi-functionality reduces the need for separate specialized components for each task, thereby reducing overall device complexity despite using multiple sensors.
