Solution Overview
Problem
Existing uninterruptible power supply devices face challenges in compactly allowing wire entry from both the upper and lower surfaces, leading to increased size and complexity due to the need for additional components or enlarged wiring spaces.
Innovation Solution
A compact uninterruptible power supply device design featuring a housing with openings on both the upper and lower surfaces, allowing wire entry without the need for additional components or enlarged spaces, and incorporating a fan unit for heat dissipation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a wire entry board is provided separately from the board body to lead wire from the bottom plate, then wire entry from both upper and lower surfaces is enabled, but the device becomes complicated and increased in size
Solution Approach 1:
The board body is designed with universal wire entry capability through integrated openings in both the upper and lower plates, eliminating the need for a separate wire entry board. The board body itself performs the wire guiding function that would otherwise require an additional component, thereby reducing device complexity while maintaining adaptability for wire entry from both surfaces.
Solution Approach 2:
The wire entry function is merged into the board body structure by forming openings directly in the upper and lower plates. This integration combines the housing structure and wire entry functionality into a single unified component, removing the need for a separate wire entry board and reducing overall device complexity.
2Adaptability or versatility
If a terminal is provided on the rear surface of the board body to respond to wire entry from both surfaces, then wire entry flexibility is improved, but the installation area increases due to required wiring space on the rear surface
Solution Approach 1:
Instead of providing wiring space on the rear surface (two-dimensional expansion), the invention utilizes the thickness dimension of the board body by forming openings in the upper and lower plates. Wires pass through these openings from opposite directions, enabling flexible wire entry without increasing the installation footprint on any single surface.
Solution Approach 2:
The wire entry function is segmented into two separate openings located in different plates (upper and lower plates) rather than concentrating all wiring space on the rear surface. This segmentation allows wires to enter from both surfaces independently without requiring additional area on the rear surface, maintaining compact installation footprint.
3Adaptability or versatility
If a wiring space is increased to accommodate more wires and larger wire diameters, then wire entry capability is improved, but the size of the device increases
Solution Approach 1:
Instead of uniformly increasing the wiring space throughout the device, the invention provides localized openings in the upper and lower plates where wires need to enter. The wiring paths are confined to specific localized regions along the wire routing paths, allowing accommodation of various wire sizes without increasing the overall device volume.
