Slide rail mechanism and bracket device thereof
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing slide rail mounting frames for servers are limited by the length of the outer rail and adjustable degree of the bracket, restricting their usage as they require a long outer rail to lock or release the slide rail rear mounting frame effectively.
Innovation Solution
A slide rail mechanism comprising a rail member, first and second supporting frames, and a bracket, where the second supporting frame drives the mounting member to move relative to the side wall of the first bracket, allowing for adjustable positioning and mounting through a supporting passage with limiting features and elastic members for secure locking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a long outer rail is used to lock or release the slide rail rear mounting frame, then the locking reliability is improved, but the device complexity and installation space requirements increase
Solution Approach 1:
The mounting frame is divided into a front mounting frame and a rear mounting frame that can move relative to each other along the rail member. The rear mounting frame includes a mounting member that can be independently positioned and locked, allowing the locking function to be separated from the entire rail assembly. This segmentation enables reliable locking without requiring the entire outer rail to be long and complex.
Solution Approach 2:
The rear mounting frame is designed to be movable relative to the front mounting frame along the rail member, transitioning between a first position (for locking) and a second position (for release). This dynamic design allows the mounting member to be positioned at different locations along the rail, enabling reliable locking at various points without requiring a fixed long rail structure.
2Manufacturing precision
If the slide rail mechanism uses a fixed mounting structure, then the manufacturing precision is improved, but the adaptability to different rack configurations decreases
Solution Approach 1:
The rear mounting frame is designed to slide along the rail member between a first position and a second position, allowing the mounting member to be positioned at different locations. This dynamic positioning capability enables the same mounting structure to adapt to different rack configurations and post positions while maintaining manufacturing precision through guided movement and limiting features.
Solution Approach 2:
The rail member with supporting passage and limiting features serves multiple functions: it guides the movement of the rear mounting frame, limits the positioning range to ensure precision, and allows the mounting member to engage with posts at different positions. This universal design enables the same structure to work with various rack configurations without requiring custom-made components.
3Stability of the object's composition
If the mounting member is fixed relative to the bracket, then the structural stability is improved, but the ease of operation for installation and removal decreases
Solution Approach 1:
The mounting member is designed to move relative to the first bracket between different positions. During installation, the mounting member can be positioned to engage with the post; during removal, it can be retracted. This dynamic design maintains structural stability when engaged while enabling easy operation for installation and removal.
Solution Approach 2:
The second supporting frame acts as an intermediary mechanism that drives the mounting member to move relative to the first bracket. By operating the second supporting frame, the mounting member is indirectly controlled to achieve engagement or disengagement from the post, maintaining structural stability during operation while enabling easy installation and removal.

AI summary
A slide rail mechanism includes a rail member, a supporting frame and a bracket. The supporting frame is movable relative to the rail member and the bracket. The bracket includes a side wall and at least one mounting member adjacent to the side wall. The at least one mounting member configured to pass through a mounting hole of a post. When the supporting frame is moved relative to the bracket from a first position to a second position, the supporting frame is configured to drive the at least one mounting member to move relative to the side wall.
