Slide Rail Assembly With Extension Limiting for Heavy Chassis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing slide rail assemblies for heavier chassis systems are prone to deformation during operation and maintenance, posing safety risks due to the inability to handle the weight effectively.
Innovation Solution
A slide rail assembly with a blocking feature, a movable second rail, a first releasing member, and a limiting member that allows safe operation and maintenance by preventing excessive extension and ensuring secure engagement and disengagement mechanisms to manage weight distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the slide assembly is totally pulled out to carry heavier chassis, then the chassis system can be fully extended for maintenance, but the slide assembly is at risk of deformation causing safety issues
Solution Approach 1:
The patent applies preliminary action by providing a blocking feature on the first rail that prevents the second rail from being fully pulled out. This blocking feature is positioned to limit the extension distance before the chassis reaches a safe position, thereby preventing deformation of the slide assembly while still allowing sufficient extension for maintenance operations.
2Weight of moving object
If the slide assembly is designed to support heavier chassis, then the load capacity is increased, but the risk of deformation and safety issues increases
Solution Approach 1:
The blocking feature is pre-positioned on the first rail to limit the extension distance. This preliminary action ensures that even when heavier chassis are mounted, the slide assembly cannot be pulled out beyond a safe distance, preventing deformation and maintaining safety while supporting increased load capacity.
3Reliability
If the second rail is restricted from full extension to prevent deformation, then safety is improved, but the ease of operation for maintenance is reduced
Solution Approach 1:
The blocking feature allows the second rail to extend partially - sufficient for maintenance operations but not excessively far to cause deformation. This partial action provides a compromise that maintains safety while still enabling adequate accessibility for maintenance tasks.

AI summary
A slide rail assembly includes a first rail, a second rail, a releasing member and a limiting member. The second rail is movable relative to the first rail. The releasing member is mounted on the second rail. The limiting member is arranged to be corresponding to the releasing member. The limiting member is configured to be in a free status and a limiting status. When the limiting member is in the free status, the releasing member is configured to be operatively moved from a first position to a second position. When the limiting member is in the limiting status, the releasing member is not able to be operatively moved from the first position to the second position.
