Pull-Out Hard Disk Bracket With Angle-Opening Sliding Rails
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hard disk brackets are complex and cumbersome to assemble, with sliding rails prone to loss and difficult to install and detach, requiring the hard disk and sliding rail to be assembled into a module before installation, and the sliding rails cannot be opened at an angle for easy access.
Innovation Solution
A pull-out hard disk bracket with two mirror-symmetrical partition plate modules that allow the hard disk to be detachably clamped and fixed, featuring sliding rails with elastic walls and guiding slopes that enable the rails to rotate at angles for easy installation and detachment, using a flexible resilient material for enhanced flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the sliding rails are arranged in parallel at two sides, then the hard disk can be fixed stably, but the sliding rails cannot be opened at a certain angle making it difficult to install and detach the hard disk
Solution Approach 1:
The sliding rails are designed to be rotatable relative to the partition plate through a rotating assembly comprising a rotating plate and connecting components. This allows the rails to transition from a fixed parallel arrangement to an opened configuration at specific angles, enabling easy insertion and removal of hard disks while maintaining stable fixing during operation
Solution Approach 2:
The bracket is divided into modular components including partition plates, sliding rails, and rotating assemblies that can independently move. This segmentation allows the sliding rails to be opened at angles for disk removal while the partition plates remain fixed, resolving the contradiction between stability and ease of operation
2Ease of operation
If the hard disk and sliding rail are assembled into a module before installation, then the installation process is simplified, but the sliding rail is easy to be lost when shipped as an accessory package
Solution Approach 1:
The sliding rail is integrated directly with the partition plate through the rotating assembly mechanism, forming a unified structure. This eliminates the need for separate accessory packages and prevents component loss while maintaining the simplified installation process, as the rail cannot be separated or lost during shipping
3Reliability
If a complex hard disk bracket is used, then the hard disk can be securely fixed, but the bracket is costly and complicated to assemble
Solution Approach 1:
The rotating assembly incorporates elastic components and guiding slopes that enable automatic engagement and locking when the sliding rail is rotated. This self-service mechanism eliminates the need for complex manual assembly steps while maintaining secure hard disk fixation, reducing both assembly complexity and cost
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
Facilitates quick and stable mounting and removal of hard disks by allowing the sliding rails to open at adjustable angles, simplifying assembly and reducing the risk of rail loss, while maintaining structural stability and ease of use.
Implementation Method 1
an elastic wall is provided on one side of the inner end of the sliding rail body, and the elastic wall can be slidingly clamped in the elastic wall sliding slot
Implementation Method 2
an end of the sliding wall adjacent to one side of the elastic wall is provided with a guiding slope; the sliding wall can drive the sliding rail body to rotate towards one side of the partition plate body by the abutment of the guiding slope with the sliding rail guide slot by a first angle

AI summary
A pull-out hard disk bracket for server chassis is disclosed, comprising two partition plate modules arranged in mirror symmetry to fix a hard disk therebetween. The partition plate module each includes a partition plate and a sliding rail, wherein the sliding rails of the two partition plate modules may open to a certain angle to install/remove the hard disk between the two partition plate modules.
