Front-Accessible UPS Module Connection Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional uninterruptible power supplies require a large work area for installation due to input-side and output-side connection wiring being placed on the back side of modules, making it difficult to install them near walls and increasing the space needed for installation.
Innovation Solution
The uninterruptible power supply design includes connection members that connect input-side and output-side switches of multiple modules at the front side, eliminating the need for a work area between modules and the wall, allowing for easier installation and reduced space requirements, with adjustable current capacity through parallel second connection members.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If connection wiring is provided on the back side of modules, then electrical connectivity is achieved, but installation work area increases
Solution Approach 1:
The patent inverts the conventional arrangement by moving connection terminals from the back side to the front side of the modules. This allows connection wiring to be accessed from the front, eliminating the need for additional work area between modules and walls, while maintaining reliable electrical connectivity through the same terminal connection mechanism
2Volume of moving object
If modules are disposed near wall surface, then space utilization is improved, but connection wiring installation becomes difficult
Solution Approach 1:
By inverting the connection terminal location from back-side to front-side, the patent enables modules to be installed close to walls while maintaining ease of connection wiring installation. The front-side accessible terminals allow wiring to be connected without requiring space between the module back and the wall
3Area of stationary object
If connection members are disposed at front side positions, then installation work area is reduced, but internal module structure becomes more complex
Solution Approach 1:
The patent resolves the structural complexity issue by utilizing the front-side dimension of the module housing for terminal placement. This spatial reorganization allows connection terminals to be accessible from the front without interfering with internal power conversion components, achieving compact design through dimensional optimization rather than increasing internal complexity
