Unmanned Flight Device Contact Detection and Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing unmanned flight equipment using linear members for cargo delivery often experiences attitude destabilization due to external forces, such as wind or manual interference, when the cargo is suspended from the aerial vehicle.
Innovation Solution
Incorporating a contact detection unit with a carbon microcoil-based linear member contact detection sensor and a separation unit that can sever the linear member or cargo from the aerial vehicle upon detection of contact or tension, preventing destabilization by separating the delivery target before a strong external force is applied.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a linear member is suspended from the aerial vehicle to hold the delivery target, then the cargo can be delivered while the aerial vehicle stays in midair without landing, but external forces such as wind or manual interference may act on the delivery target or linear member to destabilize the flight state of the aerial vehicle
Solution Approach 1:
The contact detection sensor detects contact forces before they can significantly destabilize the aerial vehicle. By detecting contact early and triggering separation before the full impact occurs, the system performs the protective action in advance, preventing the destabilizing effect from fully manifesting
Solution Approach 2:
The system converts the potentially harmful contact force into a useful detection signal. The contact detection sensor uses the applied force itself as the trigger mechanism for separation, transforming the destabilizing influence into the activation condition for the protective response
2Stability of the object's composition
If an adjustment means is provided to adjust the fixing of the linear member according to the aerial vehicle's attitude, then the load of the cargo can constantly act on the center of gravity enabling stable flight, but the device complexity increases
Solution Approach 1:
The patent extracts the complex adjustment means from the fixing device and replaces it with a simpler separation mechanism. Instead of continuously adjusting the linear member's position to maintain stability, the system simply separates the delivery target when contact is detected, removing the need for complex real-time adjustment mechanisms
Solution Approach 2:
Rather than trying to prevent destabilization through continuous adjustment, the system inverts the approach by preparing for and enabling quick separation when destabilization occurs. The focus shifts from maintaining the connection under varying conditions to breaking the connection when necessary, simplifying the overall system
3Reliability
If the linear member is pulled by external forces, then the delivery target may be detached, but the aerial vehicle's attitude cannot be maintained and flight is destabilized
Solution Approach 1:
The contact detection sensor provides real-time feedback on forces applied to the linear member or delivery target. This feedback loop allows the control system to monitor the tension and trigger separation when predetermined contact thresholds are exceeded, creating a closed-loop control system that responds to actual conditions
Solution Approach 2:
The system applies preliminary anti-action by detecting contact forces and triggering separation before the full destabilizing effect can occur. The separation action is initiated in response to the contact detection, counteracting the potential harm before it fully manifests in the flight stability
