Slide rail assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing slide rail assemblies struggle to synchronize movement between rails due to installation tolerance gaps, leading to unsynchronized movement failures.
Innovation Solution
A slide rail assembly with an auxiliary member that unsynchronizes movement between rails by using a synchronization member, engaging member, and auxiliary member, where the blocking feature on one rail interacts with the auxiliary member to switch the synchronization member's state, preventing further movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a synchronization member is used to synchronize movement between rails, then movement synchronization is improved, but installation tolerance gaps cause the synchronization to fail
Solution Approach 1:
The patent introduces an auxiliary member as an intermediary component between the blocking feature and the synchronization member. This auxiliary member acts as a mediator that can be selectively engaged or disengaged to control the interaction between the blocking feature and synchronization member, allowing the system to accommodate installation tolerance gaps while maintaining reliable synchronization when needed.
Solution Approach 2:
The patent makes the synchronization system dynamic by allowing the auxiliary member to switch between different positions (first position where it blocks the blocking feature, and second position where it allows engagement). This dynamic capability enables the system to adapt to varying installation conditions, transitioning between synchronized and unsynchronized states as needed.
2Stability of the object's composition
If the synchronization member continuously synchronizes rail movement, then movement coordination is improved, but the ability to unsynchronize for different market requirements is lost
Solution Approach 1:
The auxiliary member provides dynamic control over the synchronization mechanism, allowing the system to switch between synchronized and unsynchronized states. This enables the rail assembly to adapt to different market requirements by selectively engaging or disengaging the synchronization function while maintaining stable coordinated movement when synchronization is needed.
Solution Approach 2:
The patent changes the operational parameter of the synchronization system by introducing the auxiliary member that can alter the engagement state between the blocking feature and synchronization member. This parameter change allows the system to transition between different operational modes (synchronized vs. unsynchronized) to meet varying market requirements.

AI summary
A slide rail assembly includes a first rail, a second rail, a synchronization member, an auxiliary member and a third rail. The synchronization member is movably mounted on the second rail. The third rail is arranged with a working feature. During a process of the third rail being moved along an opening direction, the third rail is configured to drive the second rail to synchronously move by the working feature abutting against the synchronization member. During a process of the third rail and the second rail being synchronously moved along the opening direction, the blocking feature is configured to abut against the auxiliary member to move the auxiliary member relative to the second rail, in order to drive the synchronization member to move to no longer abut against the working feature, so as to unsynchronize movement between the third rail and the second rail.
