Illuminated Power Supply Handle With Shortened Flexible PCB Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The use of flexible circuit boards in illuminated handles for power supply devices is costly due to the need for additional insulation components, increasing overall costs and complexity.
Innovation Solution
The integration of a light source set with a fan assembly and handle, where the flexible printed circuit board is positioned on the handle's end surface, reduces the length of the circuit board and eliminates the need for additional insulation, thereby lowering costs and meeting safety regulations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If flexible circuit board is connected to rear control board through transformers, then illuminated handle function is achieved, but additional insulation components are required increasing cost
Solution Approach 1:
The flexible circuit board is extracted from the traditional routing path that passes through transformers and is repositioned to be disposed on the end surface of the handle. This extraction eliminates the need for additional insulation components while maintaining electrical connectivity through a direct wire connection to the control board.
2Reliability
If flexible circuit board is routed through transformers, then illuminated handle is powered, but overall cost increases due to insulation components
Solution Approach 1:
The flexible circuit board is extracted from the costly routing path through transformers and repositioned on the handle's end surface, eliminating the need for expensive insulation components like double-layer high-temperature adhesive tape while maintaining the power supply function.
Solution Approach 2:
The flexible circuit board is moved from a three-dimensional routing path through the device interior (passing through transformers) to a two-dimensional surface placement on the handle's end surface, simplifying the overall structure and reducing costs.
3Reliability
If flexible circuit board is used in traditional configuration, then illuminated handle function is achieved, but flexible circuit board length is excessive
Solution Approach 1:
The flexible circuit board is extracted from the lengthy traditional routing path and repositioned close to the light source on the handle's end surface, dramatically shortening its length while maintaining electrical connectivity through direct wire connection to the control board.

AI summary
A power supply device including a device body, a fan assembly, and a light source set and a handle. The device body includes a case and a control board, and the control board is disposed in the case. The fan assembly is disposed in the case. The light source set is disposed on the side of the fan assembly and includes a flexible printed circuit board and a wire. The wire is electrically connected to the flexible printed circuit board and connected to the control board. The handle is combined with the fan assembly, and at least a part of the flexible printed circuit board is disposed on an end surface of the handle facing the fan assembly. As a result, users may extract the power supply device under environments with insufficient light by exerting a force on the handle.
