UAV Power Supply Assembly with Segmented Circuit Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The miniaturization of remote control mobile apparatuses, such as UAVs, makes it inconvenient to assemble, disassemble, or repair the main structural frame due to the integration of functional circuits on a single circuit board, which hinders maintenance and debugging.
Innovation Solution
A power supply assembly is designed with a polyhedron mounting bracket that separates functional circuits on different outer surfaces, allowing for easier installation, debugging, and disassembly, while maintaining a compact structure by utilizing the inner cavity space effectively and facilitating airflow and heat dissipation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If all functional circuits are integrated on a single circuit board inside the housing, then the device achieves miniaturization, but assembly, disassembly, and repair become inconvenient
Solution Approach 1:
The patent divides the integrated circuit board into multiple separate functional circuits that are arranged on different outer surfaces of the mounting bracket. This segmentation allows individual circuits to be accessed, assembled, disassembled, and repaired independently while maintaining the compact overall structure of the device.
2Volume of moving object
If functional circuits are integrated on a single circuit board, then device size is reduced, but debugging and maintenance become difficult
Solution Approach 1:
By segmenting the functional circuits and placing them on different outer surfaces of the mounting bracket, the patent enables technicians to access and debug specific circuits without disassembling the entire device. Each circuit can be independently tested and maintained while preserving the compact form factor.
3Ease of repair
If functional circuits are arranged on different outer surfaces of the mounting bracket, then assembly and maintenance become easier, but device volume increases
Solution Approach 1:
The patent utilizes the three-dimensional space of the mounting bracket by arranging functional circuits on different outer surfaces rather than spreading them out in a single plane. This dimensional arrangement allows multiple circuits to be positioned on the exterior surfaces of the bracket, providing easy access for maintenance while minimizing the overall device volume through effective use of available space.
