Rotating Riser Tray Layout for Double-Layer Server Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing server designs with a double-layer structure require users to remove the expansion module from the upper layer before replacing electronic components on the lower layer, leading to complicated assembly and disassembly processes and inadequate cable management.
Innovation Solution
A server device featuring a movable tray and a riser module that allows the tray to rotate relative to the chassis, enabling the motherboard and riser module to be accessed without removal, simplifying assembly and disassembly and improving cable management through electrical connections and airflow guidance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the server uses a double-layer structure with expansion module on upper layer and motherboard on lower layer, then space utilization is improved, but the complexity of assembling and disassembling components increases
Solution Approach 1:
The movable tray is designed to be rotatable relative to the chassis, transforming the static double-layer structure into a dynamic one. This allows the expansion module to be rotated away from the motherboard area, enabling access to lower layer components without complete disassembly, thus resolving the contradiction between space utilization and assembly complexity
Solution Approach 2:
The server structure is segmented into movable tray (holding expansion module) and fixed chassis (holding motherboard). This segmentation allows independent movement of the expansion module via the rotatable tray, enabling access to motherboard components without removing the entire expansion module, thereby reducing assembly complexity while maintaining space utilization
2Volume of moving object
If the expansion module is fixed on the upper layer, then space utilization is improved, but the ease of operation for cable management and component access deteriorates
Solution Approach 1:
The movable tray enables dynamic repositioning of the expansion module by rotating away from the motherboard area when access is needed. This dynamic capability allows cable management and component access operations without sacrificing the space-efficient double-layer configuration, resolving the contradiction between space utilization and ease of operation
Solution Approach 2:
The movable tray is positioned and locked in place during normal operation to maintain the compact double-layer structure. When access is needed, the tray is rotated to a preliminary access position that clears the workspace, allowing cable management and component access before being returned to the operational position, thus maintaining both space utilization and ease of operation
