Rack Server Power Supply Stacking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Rack server systems are bulky due to the space occupied by electronic devices and cables, leading to inefficient use of space and increased size.
Innovation Solution
The server system design includes a rack with a power supply and network switch device stacked vertically, with power cables entering from the front to connect to the power supply, reducing the overall size by eliminating the need for side-by-side arrangement and internal power supplies within servers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If power supplies are installed in each server individually, then each server has independent power capability, but the overall system size increases and space is wasted
Solution Approach 1:
The patent consolidates power supplies from individual servers into a shared power supply unit located in the rack. Multiple servers share common power supply resources, reducing redundant components and overall system volume while maintaining power delivery capability to each server through power distribution units.
Solution Approach 2:
The shared power supply unit serves multiple servers simultaneously, providing universal power distribution capability. The power supply system is designed to accommodate multiple servers with different power requirements through modular power distribution, eliminating the need for dedicated power supplies in each server.
2Ease of operation
If electronic devices and cables are installed inside the rack, then all components are accommodated in one space, but the rack becomes bulky and space utilization decreases
Solution Approach 1:
The patent utilizes vertical stacking arrangements and three-dimensional space optimization within the rack. Power supplies, network switches, and servers are arranged in vertical layers, efficiently utilizing the rack's height dimension. Cables are routed through dedicated channels and bundles, organizing them in a compact manner that minimizes horizontal space occupation.
Solution Approach 2:
The design implements nested arrangements where smaller components are positioned within or between larger structural elements. Power distribution units are integrated into rack mounting structures, and cable management systems are embedded within rack frameworks, maximizing space utilization without increasing external dimensions.
3Ease of manufacture
If power cables penetrate through the rack structure, then power can be delivered to internal components, but the cable routing becomes complex and assembly difficult
Solution Approach 1:
The patent extracts power cable entry points to the front panel of the rack, where cables can be connected externally without penetrating through the rack structure. Power cables connect to power distribution units through accessible front-panel interfaces, simplifying cable routing and assembly while maintaining power delivery capability to internal components.
Solution Approach 2:
Power distribution units serve as intermediary components between external power sources and internal servers. These units provide standardized power interfaces and cable management, simplifying the connection between power cables and multiple servers. The intermediaries organize cable connections and reduce routing complexity through modular design.

Function Achieved in This Case
This configuration reduces the server system's size, saves costs by eliminating the need for internal power supplies in each server, and enhances assembly convenience while maintaining efficient power and network connectivity.
Implementation Method 1
The power cable is used for transmitting an external alternating current. The power supply is used for converting the alternating current into a direct current.

AI summary
A server system includes a rack, at least one server, a power supply, a network switch device and a power cable and. The rack has a front side and a rear side disposed oppositely. The rack defines an upper area, a middle area and a lower area. The middle area is disposed between the upper and the lower area. The servers are detachably disposed in the upper or the lower area. Each server having a power input port. The power supply is disposed in the middle area and adjacent to the front side. The network switch device is disposed in the middle area and stacked with the power supply. A gap is disposed between the network switch device and the power supply. The power cable penetrates through the gap to the front side. The power supply converts an external alternating current from the power cable to the server.
