Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple sensors are deployed to detect and identify UAVs, then measurement precision and reliability improve, but device complexity increases
Solution Approach 1:
The system segments the detection task across multiple independent sensor types (video sensors for visual identification, audio sensors for noise detection, RF sensors for communication signals, Wi-Fi sensors for network signals). Each sensor type processes specific aspects of UAV detection independently, improving measurement precision while allowing modular complexity management.
Solution Approach 2:
The sensor system is designed with multi-functionality where each sensor type serves multiple purposes: video sensors identify UAV presence and track movement, audio sensors detect rotor noise patterns, RF sensors capture communication signals, and Wi-Fi sensors detect network transmissions. This universal approach allows comprehensive UAV identification through diverse data sources.
2Reliability
If real-time UAV detection and tracking is implemented, then airspace safety improves, but processing time and computational resources increase
Solution Approach 1:
The system performs preliminary actions by continuously monitoring and pre-processing sensor data even when no UAV is currently detected. Video sensors maintain ready-to-analyze frames, audio sensors pre-process noise patterns, and RF sensors continuously scan frequencies. This preliminary preparation reduces processing time when a UAV appears, enabling faster real-time response while maintaining airspace safety.
3Measurement precision
If comprehensive sensor data collection is performed to distinguish malicious from benign UAVs, then measurement precision improves, but loss of information increases due to the volume of data to be processed
Solution Approach 1:
The system extracts only the most relevant features from comprehensive sensor data for analysis. Video sensors extract motion patterns and visual characteristics, audio sensors extract noise frequency patterns, RF sensors extract communication signal characteristics, and Wi-Fi sensors extract network protocol information. By extracting only essential features rather than processing all raw data, the system maintains high classification accuracy while reducing data management burden.
