Slide Rail Interlock Device to Prevent Rack System Overbalancing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Rack systems with slide rail assemblies face instability when multiple objects are pulled out simultaneously, risking overbalancing due to shifted center of gravity, and existing interlock devices may not effectively manage this issue for diverse equipment configurations.
Innovation Solution
A rack system incorporating a slide rail assembly with an interlock device that includes a linking member, a first locking member, and an engaging member, where the second rail of the slide rail assembly displaces the linking member from a retracted to a predetermined position, triggering the interlock device to prevent excessive movement and maintain balance by blocking the second rail of the slide rail assembly.

Engineering Contradiction Analysis
1Productivity
If multiple objects are pulled out simultaneously from the cabinet, then the accessibility and operational efficiency are improved, but the cabinet becomes unstable and may topple due to shifted center of gravity
Solution Approach 1:
The interlock device applies preliminary anti-action by preventing the second object from being pulled out when the first object is already extracted. The interlock mechanism detects the position of the first slide rail assembly and blocks the second slide rail assembly accordingly, counteracting the potential instability before it occurs. This ensures that only one object can be pulled out at a time, maintaining cabinet stability while still allowing sequential access.
2Stability of the object's composition
If an interlock device is implemented to prevent overbalancing, then the cabinet stability is improved, but the device complexity increases due to additional interlocking mechanisms
Solution Approach 1:
The interlock device merges the stability control function with the existing slide rail assembly structure. The interlock mechanism is integrated into the slide rail assemblies themselves, using the moving rails and fixed rails as part of the interlocking system. This combining approach reduces overall device complexity by eliminating separate, standalone interlock mechanisms while still achieving the stability control objective.
3Manufacturing precision
If a specific interlocking mechanism is designed for rack-mounted equipment of specific shapes or configurations, then the manufacturing precision and fit are improved, but the adaptability to different equipment configurations decreases
Solution Approach 1:
The slide rail assembly with interlock device is designed with universal applicability to accommodate different equipment configurations. The interlock mechanism works with the general structure of slide rail assemblies regardless of the specific equipment mounted. The system can adapt to various equipment shapes and configurations while maintaining precise fit and stability control, achieving both manufacturing precision and versatility through its universal design approach.

AI summary
A slide rail assembly includes a supporting rail (106), a first rail (48), a second rail (50), and an interlock device (72). The second rail (50) can be displaced with respect to the first rail (48). The interlock device (72) is movably disposed between the first rail (48) and the supporting rail (106). The second rail (50) displaces the interlock device (72) while being displaced from a retracted position (L1) with respect to the first rail (48) to a predetermined position (L2) in an opening direction.
