Bracket device and slide rail assembly comprising the same
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing slide rail mounting systems require continuous external force to maintain the post locking mechanism in an unlocking state, which is impractical when multiple server devices are stacked on a rack, leaving no space for users to apply the necessary force for installing slide rails to both front and rear posts.
Innovation Solution
A slide rail assembly with a bracket device that includes a supporting frame, a second bracket, an elastic member, and a fastening member, where the elastic member accumulates force to switch the fastening member from a locking to an unlocking state, allowing one-man operation for mounting and locking the slide rail to the rack posts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a back locking mechanism with a post locking plate is used, then the slide rail can be securely locked to the rack post, but continuous external force is required to maintain the unlocking state for installation
Solution Approach 1:
The elastic piece serves as a self-service mechanism that automatically maintains the post locking plate in the locked state without requiring continuous external force. The elastic force inherently provides the necessary holding force, eliminating the need for manual intervention to maintain the locking state.
Solution Approach 2:
The installation process utilizes periodic action where the user applies force intermittently - first to unlock, then to lock - rather than requiring continuous force application. The elastic piece maintains the locked state automatically after the initial locking action, allowing the user to move on to installing the other end of the slide rail.
2Quantity of substance
If multiple server devices are stacked on the rack, then the rack capacity is maximized, but no extra space remains for users to apply external force for mounting slide rails
Solution Approach 1:
The elastic piece provides self-service by automatically maintaining the locking state through its elastic force, eliminating the need for additional space where users could apply continuous external force. The mechanism works within the confined space created by densely stacked servers.
Solution Approach 2:
The elastic piece is pre-loaded during manufacturing to provide the necessary elastic force. This preliminary action ensures that the locking mechanism can operate reliably in the limited space available when multiple servers are stacked on the rack.
3Ease of operation
If a user continuously applies external force to keep the back locking mechanism open, then the slide rail can be mounted to the front post, but the user cannot simultaneously mount the rear post
Solution Approach 1:
The elastic piece maintains the locking state automatically, allowing the user to quickly switch between mounting the front and rear posts without losing time continuously holding the mechanism open. This self-maintaining feature enables efficient one-man operation for mounting both ends of the slide rail.
Solution Approach 2:
The installation process uses periodic actions where the user mounts the front post, releases the mechanism, then mounts the rear post - rather than continuously holding the mechanism open. This allows efficient sequential installation of both posts by a single user.
Applied Scientific Principles

Function Achieved in This Case
Enables convenient and quick mounting and locking of slide rails to rack posts without the need for continuous external force, facilitating one-man operation and improving installation efficiency.
Implementation Method 1
an elastic member having a first portion movably mounted to the supporting frame, and a second portion bent relative to the first portion and connected to the fastening member for providing an elastic force

AI summary
A bracket device includes a supporting frame, a bracket, an elastic member and a fastening member. The bracket is movably connected to the supporting frame. The elastic member is mounted to the supporting frame. The fastening member is connected to the elastic member. When the bracket is located at a first position relative to the supporting frame, the fastening member is in a locking state. When the bracket is located at a second position relative to the supporting frame, the fastening member is in an unlocking state.
