Uninterruptible Power Supply Vertical Component Stacking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing uninterruptible power supplies with power converters require lengthy conducting wires to connect devices, increasing power loss and complicating connection operations, which can lead to reduced workability and stability.
Innovation Solution
The configuration of an uninterruptible power supply with an input switch, input filter, and power converter disposed in order from top to bottom, and an output filter and output switch disposed in order from the power converter to the top, using conductors to connect these components directly, reducing the need for wires across non-connected devices and improving workability and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the output filter unit case is disposed between the converter unit case and inverter unit case, then the devices are arranged in a compact configuration, but the length of conducting wires connecting the converter to the inverter is increased
Solution Approach 1:
The patent repositions the output filter unit case to the lower side of the converter unit case in the vertical dimension, rather than placing it between units in the horizontal plane. This dimensional change allows the conducting wire to connect the converter and inverter directly in the horizontal direction, significantly reducing wire length while maintaining compact overall footprint.
2Adaptability or versatility
If lengthy conducting wires are used to connect devices, then device placement flexibility is improved, but power loss increases and workability deteriorates
Solution Approach 1:
The patent applies local quality by strategically positioning the output filter unit case in a specific location (lower side of converter unit case) that optimizes the local wire routing path. This localized spatial arrangement minimizes the length of conducting wires in the critical power transmission path between converter and inverter, thereby reducing power loss while preserving overall device placement flexibility.
3Length of stationary object
If the input switch is disposed on the lower side near the installation surface, then the overall unit height is reduced, but connection workability is worsened due to bent-forward posture requirements
Solution Approach 1:
The patent positions the input switch unit case on the upper side of the inverter unit case in the vertical dimension, creating a tiered arrangement. This dimensional placement allows workers to access the input switch from above while maintaining a standing posture, improving connection workability while keeping the overall unit height compact through efficient vertical stacking.
