Server Cabinet Slide Rail Support for Stable Chassis Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current server cabinet holding structures face challenges in providing sufficient support strength while minimizing space occupancy, leading to increased chances of hard disk damage due to instability and reduced stacking capacity.
Innovation Solution
The proposed solution involves a cabinet holding structure with a pair of slide rails and supporting components, including a positioning plate, screw nut, supporting plate, stud, and screw bolt, which are assembled on the slide rails to securely position the chassis, allowing for adjustable support and stable combination within the cabinet.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a three-stage slide rail structure is used, then the support strength is improved, but the space occupied inside the chassis increases
Solution Approach 1:
The slide rail structure is divided into multiple segments: outer slide rail, first sliding bushing, middle slide rail, second sliding bushing, and inner slide. Each segment performs a specific function, allowing the system to achieve high support strength while optimizing space utilization through modular arrangement.
Solution Approach 2:
The slide rail components are nested within each other in a concentric arrangement, with the inner slide contained within the middle slide rail, which is contained within the outer slide rail. This nesting approach minimizes the overall space occupied while maintaining the multi-stage support structure.
2Volume of moving object
If the rail structure is simplified, then the space occupied is reduced, but the support strength is lowered
Solution Approach 1:
The slide rail system combines multiple materials with different properties: metallic components for structural strength (outer slide rail, middle slide rail, inner slide) and polymeric or composite materials for the sliding bushings. This composite approach achieves high support strength while optimizing the space efficiency of each component.
Solution Approach 2:
The sliding bushings provide dynamic movement capability between the nested rail components, allowing the structure to adapt to operational forces while maintaining compact dimensions. The dynamic interface enables the simplified compact structure to achieve the support strength of more complex designs.
3Stability of the object's composition
If the slide rail support strength is insufficient, then the cabinet sways, but the hard drives are more likely to be damaged
Solution Approach 1:
The multi-stage slide rail structure with buffering bushings provides beforehand cushioning by absorbing and distributing operational forces before they can cause cabinet sway or hard drive damage. The nested structure with multiple contact points creates inherent shock absorption capability.
Solution Approach 2:
The sliding bushings act as intermediary elements between the nested rail components, providing a cushioning interface that reduces direct metal-to-metal contact and dampens vibrations. This intermediary layer prevents force transmission that could cause cabinet sway and protects hard drives from shock.

AI summary
A cabinet holding structure, the slide rails are disposed on the frames and have troughs. Supporting components are assembled on ends of the slide rails. Each supporting component includes a positioning plate, a screw nut, a supporting plate, a stud and a screw bolt. The positioning plate has a through hole and is placed on the slide rail, and the supporting plate is plated on another side of the slide rail. The stud protrudes through the trough. The screw bolt passes through the trough and the through hole to be fixed by the screw nut. The chassis includes a shell and notches. The shell is positioned on the slide rails by buckling the notches and the stud together.
