Slide Rail Assembly with Movable Stopper for Easy Unlocking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing slide rail assemblies in servers face issues where the stopper on the second rail blocks the first rail when the third rail is removed during maintenance, preventing the second rail from being received into the first rail.
Innovation Solution
A slide rail assembly design where the operating member is movably connected to the second rail and pushes the first stopper along its concave surface, eliminating the need for a linkage structure between the operating member and the stopper, thereby allowing easy unlocking and reducing manufacturing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the stopper is fixed on the second rail to form a temporary lock with the first rail, then the locking reliability is improved, but the ease of operation deteriorates when the third rail is removed during maintenance
Solution Approach 1:
The stopper is changed from a fixed structure to a movable structure that can be dynamically repositioned. The stopper includes a moving portion that can be pushed by the operating member to change its position relative to the first rail, enabling it to block or unblock the positioning means as needed for locking or unlocking operations
Solution Approach 2:
An operating member is introduced as an intermediary component between the user and the stopper. This operating member pushes the moving portion of the stopper to achieve unlocking, providing a convenient interface for users to operate the locking mechanism without directly manipulating the stopper itself
2Ease of operation
If a linkage structure is used to connect the operating member and the first stopper, then the ease of operation is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The complex linkage structure is extracted and removed from the design. Instead of using linkages to connect the operating member and stopper, the invention directly pushes the moving portion of the stopper through the concave surface, eliminating unnecessary intermediate mechanical connections while maintaining operational ease
Solution Approach 2:
The operating member and the stopper's moving portion are merged into a direct push-action relationship. The operating member directly contacts and pushes the moving portion of the stopper through the concave surface, combining what would have been separate linkage components into a simplified direct-action mechanism
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Facilitates easy unlocking of the second and first rails, reduces manufacturing costs, and prevents linkage failures, contributing to the thinning of the slide rail assembly.
Implementation Method 1
an elastic element located in the second hole to undergo displacement, and the elastic element having one end thereof connected to the first stopper and an opposite end thereof connected to the second stopper so that the elastic element provides elasticity to the first stopper and the second stopper

AI summary
A slide rail assembly includes a first rail with a positioning structure, a second rail displaceable relative to the first rail and providing a concave surface on the back to face the positioning structure, a first stopper pivotally connected to the concave surface corresponding to the first side of the positioning structure, and an operating member movably connected to the second rail and placed on the concave surface so that the operating member is on the side of the first stopper. The slide rail assembly can be installed on the side of the carrier, which can be a server case or drawer, or can be used on servers or furniture.
