Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If destructive interference methods are used to deal with unidentified UAVs, then the UAV can be neutralized, but people and property are at risk
Solution Approach 1:
The patent converts the harmful kinetic energy of the intercepted UAV into a beneficial capture mechanism. The net assembly, initially passive, becomes an effective capture tool by utilizing the target UAV's own motion and momentum to wrap the net around it, neutralizing the threat without creating additional harm to people or property.
Solution Approach 2:
The net assembly serves as an intermediary between the intercepting UAV and the target UAV. Instead of direct collision or destructive engagement, the net acts as a mediating element that gradually entangles and secures the target UAV, reducing the harmful effects of direct confrontation.
2Object-affected harmful factors
If non-destructive capture methods are used, then people and property are protected, but the capture effectiveness may be reduced
Solution Approach 1:
The net assembly transitions from a static configuration during launch to a dynamic entangling state during capture. The net's ability to deform, expand, and adapt its shape during the interception process enhances capture effectiveness while maintaining non-destructive characteristics. The system evolves from rigid deployment to flexible entanglement.
Solution Approach 2:
The net assembly is divided into multiple strands and sections that can independently move and entangle around the target UAV. This segmentation allows the net to conform to the target's shape and motion, improving capture reliability without requiring excessive force or destruction.
3Adaptability or versatility
If a net assembly is added to the UAV, then capture capability is enhanced, but the UAV's maneuverability and speed may be affected
Solution Approach 1:
The net assembly is designed with dynamic deployment characteristics, remaining compact during flight to minimize aerodynamic drag and only expanding when capture is initiated. This dynamic behavior reduces the impact on UAV speed and maneuverability during the critical interception phase while maintaining capture capability when needed.
Solution Approach 2:
The net assembly is stored in a nested or compact configuration during flight, similar to a nested doll structure. This minimizes the space occupied and reduces aerodynamic interference during high-speed maneuvering, allowing the UAV to maintain optimal performance until capture is required.
