Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing slide rail assemblies for furniture, such as drawer systems, lack a mechanism for synchronous movement of sliding auxiliary devices, leading to inefficient operation and stability issues during drawer opening and closing.
Innovation Solution
A slide rail assembly comprising a first rail, a second rail, a third rail, and synchronizing, driving, and locking mechanisms that allow for synchronous movement of sliding auxiliary devices through rolling members and meshing features, enabling coordinated movement and secure positioning of furniture parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional slide rail assemblies are used without a synchronizing mechanism, then the structure is simpler, but the sliding auxiliary devices do not move synchronously leading to instability and inefficiency
Solution Approach 1:
A synchronizing member is introduced as an intermediary element that meshes with both sliding auxiliary devices, coordinating their movement. This mediator ensures synchronous operation and stability without requiring complex control systems, resolving the contradiction between reliability and device complexity.
2Ease of operation
If a synchronizing member with meshing features is added to coordinate movement, then synchronous movement is achieved, but the device complexity increases
Solution Approach 1:
The synchronizing member combines multiple functions into a single component: it provides meshing engagement with both sliding auxiliary devices, acts as a structural connector between rails, and ensures synchronous movement. This merging approach improves ease of operation while minimizing the increase in device complexity.
3Ease of operation
If rolling members are used to facilitate movement between rails, then the movement is smoother, but the manufacturing precision requirements increase
Solution Approach 1:
The rolling members are designed as separate, modular components that can be precisely manufactured and then assembled into the slide rail assembly. This segmentation allows for specialized precision manufacturing of the rolling members independently from other components, achieving smooth movement while managing manufacturing precision requirements through focused production processes.

Implementation Method 3
The first sliding auxiliary device comprises at least one first rolling member and a first meshing feature. The second sliding auxiliary device comprises at least one second rolling member and a second meshing feature. The synchronizing member is meshed between the first meshing feature and the second meshing feature.
Implementation Method 4
The synchronizing member is meshed between the first meshing feature and the second meshing feature, allowing two sliding auxiliary devices between rails to move synchronously relative to each other.
Implementation Method 5
The first elastic member of the first driving device is configured to accumulate a first driving force in response to the swing member abutting against the locking part of the locking device, and the first driving force is configured to drive the second furniture part to move from a retrieve position to an open position relative to the first furniture part.
