Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional RADAR or transponder technology is used for collision warning systems, then the system can detect traditional aircraft, but it cannot detect drones
Solution Approach 1:
The system employs multiple sensor types (RADAR, LIDAR, acoustic sensors, optical sensors) that can detect both traditional aircraft and drones, making the collision warning system universal. Each sensor type operates on different detection principles, allowing the system to adapt to various target characteristics and maintain reliable detection across different object types.
Solution Approach 2:
The system changes detection parameters by using multiple sensor types with different operating frequencies and detection methods. RADAR uses radio waves, LIDAR uses light pulses, acoustic sensors use sound waves, and optical sensors use visible light. This multi-parameter approach enables detection of drones that may be invisible to conventional single-parameter RADAR systems.
2Adaptability or versatility
If the system uses multiple sensor types (RADAR, LIDAR, acoustic, optical), then drone detection capability is improved, but system complexity increases
Solution Approach 1:
The patent combines multiple sensor types (RADAR, LIDAR, acoustic sensors, optical sensors) into a single integrated sensor array system. This merging approach allows the system to detect drones using multiple detection methods simultaneously while managing complexity through unified system architecture and centralized processing.
Solution Approach 2:
The system segments the detection function into multiple specialized sensor types, each optimized for specific detection tasks. RADAR handles long-range detection, LIDAR provides precise ranging, acoustic sensors detect drone sounds, and optical sensors visualize drones. This segmentation allows each component to be simpler while the overall system achieves high detection capability.
3Reliability
If the system provides early warning and maneuvering time, then collision avoidance is improved, but response time requirements increase
Solution Approach 1:
The system performs preliminary detection and warning actions well before a potential collision occurs. By continuously monitoring the environment with multiple sensors and providing early warnings when drones are detected, the system gives pilots sufficient time to maneuver and avoid collisions, transforming a reactive system into a proactive safety mechanism.
