Slide rail assembly and bracket device thereof
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bracket devices for slide rail assemblies lack an effective foolproof mechanism that prevents incorrect mounting to posts, particularly without requiring a locking member and ensuring the sliding block is not configured for mounting holes.
Innovation Solution
A bracket device with a movable mounting member along a height direction, switching between positions when rotated, incorporating an extension wall with an elongated hole and features to prevent mounting at specific angles, providing a foolproof function by interfering with the mounting process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a foolproof device with a sliding block is added to prevent incorrect mounting, then mounting reliability is improved, but the device complexity increases
Solution Approach 1:
The patent combines the mounting member and foolproofing member into a single integrated component. The mounting member has a body with a mounting hole and protrusions that serve both mounting functions and foolproofing functions, eliminating the need for separate sliding blocks and positioning members, thus reducing device complexity while maintaining mounting reliability
Solution Approach 2:
The mounting member is designed to perform multiple functions: it provides mounting holes for attachment, protrusions for positioning, and integrated foolproofing features that prevent incorrect mounting. This multi-functional design eliminates the need for separate components, reducing overall device complexity while ensuring reliable mounting
2Reliability
If a locking member is used to achieve foolproof function, then mounting reliability is improved, but the device complexity increases
Solution Approach 1:
The patent eliminates the need for separate locking members by integrating the foolproofing function directly into the mounting member. The mounting member includes protrusions that engage with corresponding features on the bracket, providing automatic positioning and prevention of incorrect mounting without requiring additional locking components
Solution Approach 2:
The mounting member is designed to automatically provide foolproofing functionality through its own structural features (protrusions and mounting holes) without requiring separate locking mechanisms. The design enables self-positioning and self-protection against incorrect mounting, reducing device complexity
3Ease of operation
If the sliding block is configured to be mounted to mounting holes, then ease of operation is improved, but the foolproof function becomes ineffective
Solution Approach 1:
The patent segments the foolproofing function into separate protrusions that are part of the mounting member body, distinct from the mounting holes. The mounting holes are positioned and sized specifically for mounting purposes, while the protrusions provide foolproofing by engaging with corresponding features on the bracket, preventing incorrect mounting while maintaining ease of operation

AI summary
A bracket device of a slide rail assembly includes a longitudinal wall and a mounting member. The mounting member is movable relative to the longitudinal wall along a height direction of the longitudinal wall. When the bracket device is rotated to be switched from a first state to a second state, the mounting member is configured to be moved from a first position to a second position. When the mounting member is located at the first position, the mounting member is operable to be mounted to a rack. When the mounting member is located at the second position, the mounting member is prevented from being mounted to the rack.
