UAV Dock Battery Replacement Device Using 3D Linear Motion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional unmanned aerial vehicle (UAV) docks have a complex and voluminous carousel battery compartment that can only store a small number of batteries, increasing the vertical height and overall size, which is not suitable for fully automated flight operations.
Innovation Solution
A battery replacement device with three linear motion mechanisms that create a three-dimensional Cartesian coordinate system, allowing the clamp mechanism to adjust the battery's position without a rotary compartment, enabling compact structure and smaller volume, and facilitating direct battery insertion and removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a carousel battery compartment is used for battery storage, then batteries can be stored in the dock, but the structure becomes complicated and the volume increases
Solution Approach 1:
The battery storage system is divided into multiple independent battery slots arranged in a matrix pattern, with each slot capable of holding a battery independently. This segmentation allows for efficient space utilization while maintaining a simple overall structure, eliminating the need for a complex carousel mechanism.
2Quantity of substance
If a carousel battery compartment is used, then batteries can be stored, but the vertical height and overall size of the dock increase
Solution Approach 1:
The battery slots are arranged in a two-dimensional matrix pattern on the base plate, utilizing horizontal space efficiently rather than requiring vertical stacking. This dimensional arrangement maximizes battery storage capacity while keeping the dock's overall volume compact and minimizing vertical height.
3Productivity
If a rotary battery compartment is used, then battery replacement can be achieved, but the device occupies a larger volume
Solution Approach 1:
The clamp mechanism automatically grasps the battery from the designated slot and performs the replacement operation without requiring a rotary motion or complex positioning system. This self-service approach enables efficient battery replacement while maintaining a compact battery compartment structure.
4Ease of operation
If additional driving means are added to adjust battery orientation, then battery insertion can be facilitated, but the structure becomes more complex and cost increases
Solution Approach 1:
The clamp mechanism is designed to perform multiple functions: it grasps the battery, positions it correctly, and facilitates insertion into the slot. This multi-functional design eliminates the need for separate driving means to adjust battery orientation, thereby reducing structural complexity and cost while maintaining ease of operation.

AI summary
A battery replacement device including a first linear motion mechanism, a second linear motion mechanism mounted on the first linear motion mechanism, a third linear motion mechanism mounted on the second linear motion mechanism, and a clamp mechanism mounted on one of the first, second, and third linear motion mechanisms. Each of the first, second, and third linear motion mechanisms includes a carrying member and a driving member configured to drive the carrying member to move translationally in one of a first axis direction, a second axis direction, and a third axis direction that build a three-dimensional Cartesian coordinate system. A coordinate position of the clamp mechanism in the three-dimensional Cartesian coordinate system is adjusted by the first driving member, the second driving member, and the third driving member.
