Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Difficulty of detecting and measuring
If a detection antenna array is used to detect drone control signals, then drone detection capability is improved, but the system complexity increases
Solution Approach 1:
The system divides the detection task into multiple antenna elements arranged in an array, where each antenna contributes to the overall detection capability. The array processes signals from multiple directions simultaneously, improving detection coverage and accuracy while distributing the complexity across modular components.
Solution Approach 2:
The detection antenna array is designed to detect multiple types of electromagnetic signals in addition to drone control signals, including GPS signals and other radio frequency transmissions. This multi-functionality improves the system's versatility without requiring separate dedicated systems for each detection task.
2Object-affected harmful factors
If an override signal is transmitted to neutralize a drone, then drone safety is improved, but the risk of collateral interference increases
Solution Approach 1:
The system transmits the override signal with directional focus toward the detected drone, concentrating the neutralizing effect on the target while minimizing spread to surrounding areas. The antenna array enables spatial filtering to direct energy precisely where needed, reducing collateral interference with other electronic systems.
Solution Approach 2:
The system continuously monitors the electromagnetic environment for signs of malicious drone activity before transmitting override signals. By detecting precursor behaviors such as unauthorized control signal patterns or suspicious flight paths, the system can prepare neutralization measures in advance, responding more effectively while maintaining safety thresholds to avoid premature or erroneous interference.
