Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing base stations for UAVs require precise docking, which can be challenging due to limited landing envelopes, leading to unsuccessful landings and inefficient charging processes.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the charging hub is fixed in an extended position to facilitate electrical connection, then the docking precision is improved, but the landing envelope is reduced
Solution Approach 1:
The charging hub is made dynamically repositionable between retracted and extended positions. During landing, the hub remains retracted to maximize landing envelope. After the UAV lands and is positioned on the landing platform, the hub extends to establish electrical connection, thus achieving both large landing envelope and precise docking.
Solution Approach 2:
The system performs preliminary alignment of the UAV on the landing platform before extending the charging hub. This preliminary positioning ensures that when the hub extends, the electrical contacts are already approximately aligned, reducing the precision requirement during the extension action itself.
2Reliability
If the charging hub is retracted to increase landing envelope, then the landing success rate is improved, but the electrical connection capability is reduced
Solution Approach 1:
The charging hub transitions from a static to a dynamic component, automatically extending after landing to establish electrical connection. This dynamic behavior allows the system to prioritize landing success during approach while ensuring charging capability is maintained through post-landing extension.
Solution Approach 2:
The system performs preliminary alignment of the UAV on the landing platform before extending the charging hub. This ensures that even when the hub is retracted during landing, the UAV is positioned correctly, and the subsequent extension will successfully establish electrical connection.
3Device complexity
If a fixed charging hub configuration is used, then the device complexity is reduced, but the adaptability to different docking scenarios is limited
Solution Approach 1:
The charging hub incorporates linear actuators that enable it to extend and retract along the vertical axis. This dynamic capability allows the same simple structural design to adapt to different scenarios: retracted during landing for large envelope, extended during charging for precise connection, thus maintaining low complexity while achieving high adaptability.

AI summary
A method of docking an unmanned aerial vehicle (UAV) with a base station. The method includes: landing the UAV on a landing platform of the base station; generally aligning the UAV with a charging hub of the base station; extending the charging hub; and repositioning a locking mechanism on the charging hub from an unlocked position into a locked position to thereby secure the charging hub to the UAV.
