Modular Power Supply Bracket Layout for Reconfigurable Server Chassis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current power supply brackets for servers require replacement when the number of power supplies changes, leading to waste and increased assembly costs due to the need for customized brackets.
Innovation Solution
The design incorporates power supply brackets with engagement structures that allow modular assembly, enabling flexible installation based on the required number of power supplies without needing new brackets, thus reducing assembly costs and space usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If dedicated power supply brackets with fixed configurations are used, then the structure is simple and easy to manufacture, but the adaptability to different numbers of power supplies is poor and assembly costs increase
Solution Approach 1:
The power supply bracket is divided into multiple detachable sections, each capable of independently accommodating power supplies. The bracket consists of a first bracket section and a second bracket section that can be separated and reconfigured. This segmentation allows the bracket to adapt to different numbers of power supplies by assembling or disassembling the sections, thereby improving versatility without significantly increasing manufacturing complexity.
Solution Approach 2:
The bracket design incorporates dynamic reconfigurability through detachable connections between bracket sections. The first and second bracket sections can be connected or separated based on the required number of power supplies, transforming a static fixed-configuration bracket into a dynamic adaptable structure. This enables the same bracket components to serve multiple configurations, reducing the need for multiple dedicated brackets.
2Adaptability or versatility
If new power supply brackets are assembled when the number of power supplies changes, then the adaptability is improved, but the assembly cost increases due to waste of original brackets
Solution Approach 1:
The bracket design enables recovery and reuse of original bracket components when the number of power supplies changes. Instead of discarding the entire bracket, the detachable sections can be separated, with some sections retained and reused for the new configuration. This reduces material waste and assembly costs by recovering usable portions of the original bracket structure.
Solution Approach 2:
By segmenting the bracket into detachable sections, the design allows selective retention and reuse of specific bracket portions when reconfiguring for a different number of power supplies. This segmentation enables partial recovery of original components, reducing waste and the need to assemble entirely new brackets when adjustments are needed.
3Ease of manufacture
If fixed-configuration power supply brackets are used, then the manufacturing cost is low, but the assembly cost increases when reconfiguration is needed
Solution Approach 1:
The bracket is manufactured as segmented detachable sections rather than a single fixed structure. While this slightly increases manufacturing complexity compared to a simple fixed bracket, it enables efficient reconfiguration by allowing sections to be easily assembled or disassembled without requiring complete bracket replacement, thereby improving long-term assembly efficiency.
Solution Approach 2:
The dynamic detachable design allows the bracket to be reconfigured by simply connecting or separating sections, which is more efficient than manufacturing new fixed-configuration brackets each time the power supply number changes. This dynamic approach improves assembly productivity while maintaining reasonable manufacturing simplicity.

AI summary
An electronic device includes a chassis and a plurality of power supplies. The chassis includes a supporting tray and a plurality of power supply brackets. The power supply brackets are disposed on the supporting tray. Each of the power supply brackets includes a bracket top plate, a first bracket side plate, and a second bracket side plate. The first bracket side plate and the second bracket side plate are connected to the bracket top plate. The bracket top plate, the first bracket side plate, and the second bracket side plate together define an accommodating space. The first bracket side plate of one of the power supply brackets and the second bracket side plate of an adjacent one of the power supply brackets are held in position. The power supplies are located in the accommodating spaces.
