UAV Docking Platform Reconfiguration for Charging Hub Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing base stations for UAVs face challenges in efficiently aligning and docking UAVs with charging hubs while preventing damage during closure, leading to potential damage to both the UAV and the base station.
Innovation Solution
A reconfigurable landing platform with alignment members that can be repositioned between extended and retracted positions, facilitated by a drive mechanism with pulley assemblies and slide assemblies, to align the UAV with the charging hub and prevent contact with the roof during closure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the landing platform is kept fixed during docking, then the structure is simple, but the UAV cannot be properly aligned with the charging hub and may contact the roof during closure
Solution Approach 1:
The landing platform transitions from a fixed structure to a dynamic, reconfigurable structure that can change its configuration. The platform includes movable components such as the charging hub that can extend and retract, and the platform surface that can tilt or shift position, allowing it to adapt during the docking process to achieve precise alignment while maintaining structural simplicity.
Solution Approach 2:
The landing platform is divided into separate functional segments including the main platform surface, the charging hub assembly, and alignment mechanisms. This segmentation allows each component to move independently and be positioned precisely during docking, achieving high alignment precision without requiring the entire platform structure to be complex.
2Ease of operation
If the alignment members are kept in extended position, then the UAV is constrained during landing, but the UAV cannot be repositioned for proper alignment with the charging hub
Solution Approach 1:
The alignment members are designed as dynamic elements that can transition between extended and retracted positions. During landing, they extend to provide constraints and stability. After the UAV is secured, they retract to allow the platform to reposition the UAV for alignment with the charging hub, thus providing both landing stability and repositioning capability.
Solution Approach 2:
The alignment members extend in advance during the landing phase to establish proper constraints before the UAV needs to be repositioned. This preliminary action ensures stable landing occurs first, then allows subsequent repositioning operations to proceed without compromising the initial landing stability.
3Adaptability or versatility
If the charging hub is stationary, then the structure is simple, but it cannot accommodate UAVs with varying positions during docking
Solution Approach 1:
The charging hub is designed as a movable component that can extend and retract along the platform. This dynamic capability allows the charging hub to accommodate UAVs landing at various positions on the platform, providing adaptability without requiring the entire charging system to be complex or oversized.
4Productivity
If the platform closes quickly, then the docking process is fast, but the UAV may contact the roof causing damage
Solution Approach 1:
The alignment members extend in advance during the closing process to establish proper positioning and constraints on the UAV before the platform fully closes. This preliminary action ensures that even during quick docking operations, the UAV is properly secured and positioned, preventing contact with the roof and eliminating damage risk while maintaining high docking speed.

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 and reconfiguring the landing platform from a first configuration into a second configuration to thereby reposition the UAV on the landing platform.
