Pivoted Server Units for High-Density Rack Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge is to construct a high-density and efficient server within limited space, as traditional rack server designs occupy interior space with slide rail mechanisms, hindering functional density and scalability.
Innovation Solution
A server system featuring a swivel design with a first server unit, a second server unit, a hinge, and a connecting element, allowing the second server unit to pivot and unfold, thereby preventing interior space occupation and enhancing scalability and operational reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a slide rail mechanism is disposed in a casing to enable drawer design, then the server can be installed and removed easily, but the interior space of the casing is occupied, causing the functional density to decrease
Solution Approach 1:
The server is divided into two separate server units that can be independently installed and removed. Each server unit has its own mounting structure, eliminating the need for a shared slide rail mechanism that occupies interior space. This segmentation allows each unit to be handled separately while maintaining ease of installation and removal.
Solution Approach 2:
The mounting structure extends outward from the casing along the rack's length, utilizing the longitudinal dimension rather than occupying interior space. The mounting structure includes a mounting plate disposed at an outer surface of the casing and a mounting arm extending from the mounting plate, effectively using external space for installation functionality.
2Volume of moving object
If server units are closely packed to increase density, then space utilization improves, but accessibility for maintenance and operational reliability decrease
Solution Approach 1:
The mounting arm is designed to be movable between a retracted position (when the server unit is installed) and an extended position (when removed). This dynamic structure allows the mounting arm to extend outward to provide access to the server unit during maintenance, then retract to minimize space occupation when the unit is installed, enabling easy maintenance while maintaining high density.
Solution Approach 2:
The mounting arm acts as an intermediary mechanism that provides access to server units without requiring large gaps between them. When extended, it bridges the space between the operator and the server unit, enabling maintenance access while keeping the server units closely packed in the rack.
3Productivity
If more server units are installed in limited space, then computing capacity increases, but operational reliability may decrease due to space constraints
Solution Approach 1:
Dividing the server into separate units with independent mounting structures allows for better air flow channels between units, improved heat dissipation, and easier replacement of individual units without affecting others, thereby maintaining operational reliability while increasing computing capacity through higher density installation.
Solution Approach 2:
By utilizing the longitudinal dimension of the rack with mounting structures that extend outward, multiple server units can be installed in a compact arrangement without compromising access or cooling, enabling high computing capacity while maintaining operational reliability through proper spacing and accessibility.

AI summary
A server includes a first server unit, a second server unit, a hinge and a connecting element. The second server unit is disposed on the first server unit and is electrically connected to the first server unit. The second server unit is pivoted to the first server unit through the hinge. The connecting element is disposed between the first server unit and the second server unit. The connecting element has a first connection end and a second connection end, wherein the first connection end is connected to the first server unit, and the second connection end is connected to the second server unit. A server system including a rack and at least one server is also provided.
