Rack Server Position Identification Using Clip-Spring Contacts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In current server systems, identifying the position of a malfunctioning or replaceable server within a rack is difficult due to the lack of clear identification methods, leading to inefficient maintenance and repair processes.
Innovation Solution
A structure comprising a busbar and clip system is implemented, where each server is connected to a unique busbar via a clip with springs and a shell that defines specific connecting positions with varying hole configurations, allowing for easy identification of server locations through electrical signal generation or insulation based on spring contact with the shell.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If servers are installed densely in racks to increase capacity, then the quantity of servers increases, but the difficulty of identifying specific server positions increases
Solution Approach 1:
The busbar is divided into multiple segments, each corresponding to a specific server position. Each segment can be independently identified through the clip-spring-hole configuration, allowing individual server location identification even when multiple servers are densely installed in the rack
Solution Approach 2:
Each connecting position on the busbar has unique local characteristics defined by the specific combination of holes in the shell. This local quality differentiation allows identification of specific server positions through the electrical connection pattern, enabling position identification in dense server installations
2Device complexity
If traditional uniform connection structures are used, then the device complexity is low, but the ability to identify specific server positions is lost
Solution Approach 1:
The shell is designed with asymmetric hole distributions at different connecting positions. This asymmetry creates unique electrical connection patterns for each position, enabling position identification while maintaining a relatively simple overall structure
Solution Approach 2:
The clip and spring act as intermediaries between the server and the busbar. The spring's contact or non-contact with holes in the shell creates an intermediate electrical signal state that encodes position information, allowing position identification without complex direct connections
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables quick and accurate identification of server positions, facilitating efficient maintenance and repair by ensuring each server has a unique connection position, thereby simplifying the process of locating and removing servers from the rack.
Implementation Method 1
The springs are located outside the slot and are located on the side of the clip facing away from the busbar. The combination of the quantity and the location of the holes in the shell corresponds to a specific connecting position, so the position of the server can be identified.

AI summary
A structure for identifying the position of a server in a rack, the structure includes a busbar, a shell, and a clip. The busbar and the shell mounted in the rack. The shell defines some connecting positions, each connecting positions defines some hole-points, the shell can define a hole at each hole-point, and the quantity and the locations of the holes in each connecting position is different. The clip is connected on the server, the clip includes some springs, when the server is positioned on one of the connecting positions, the spring conductively contacts the shell through the corresponded hole-point without the hole or does not contact the shell through the corresponded hole-point with the hole, the springs are configured for identifying the combination of the connecting position where the server locates to identify the position of the server. A server system using the structure is also disclosed.
