Slide rail assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing slide assemblies fail to synchronize movement between rails due to installation tolerance gaps, leading to unsynchronized movement issues.
Innovation Solution
A slide rail assembly with a synchronization mechanism involving a blocking feature on the first rail, an auxiliary member, and an elastic structure to ensure synchronized movement between the third and second rails, which transitions to unsynchronized movement when a predetermined position is reached.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional slide assembly is used without additional synchronization mechanisms, then the structure is simple, but installation tolerance gaps cause unsynchronized movement between rails
Solution Approach 1:
The patent introduces a synchronization member as an intermediary component between the first and second rails. This member includes a blocking portion that interacts with a protrusion on the first rail and a corresponding blocking portion on the second rail, ensuring both rails move synchronously despite installation tolerance gaps. The intermediary component transfers the blocking action from one rail to the other, maintaining synchronization reliability without requiring complex direct coupling mechanisms.
2Reliability
If the synchronization mechanism blocks the auxiliary member using the blocking feature, then synchronized movement is ensured, but the device complexity increases
Solution Approach 1:
The patent merges the synchronization function with the existing auxiliary member structure. The blocking feature integrates the blocking portion and the interaction mechanism into a single component that combines the synchronization member and auxiliary member. This merging reduces the number of separate components and simplifies the overall mechanism while maintaining synchronization reliability through the integrated blocking action.

Function Achieved in This Case
Ensures reliable synchronization and unsynchronization of rail movements, maintaining functionality despite installation tolerance gaps, and preventing unintended retraction.
Implementation Method 1
The elastic member is configured to provide an elastic force to hold against the release end of the linking member and the fixation end of the locating member

AI summary
A slide rail assembly (20) includes a first rail (22), a second rail (24), a synchronization member (50) movably mounted on the second rail (24), an auxiliary member (54) and a third rail (26) arranged with a working feature (45) . During a process of the third rail (26) being moved along an opening direction, the third rail (26) drives the second rail (24) to synchronously move by the working feature (45) abutting against the synchronization member (50) . During a process of the third rail (26) and the second rail (24) being synchronously moved along the opening direction, the blocking feature (30) abuts against the auxiliary member (54) to move the auxiliary member (54), in order to drive the synchronization member (50) to move to no longer abut against the working feature (45), so as to unsynchronize movement between the third rail (26) and the second rail (24).
