Slide Rail Locking Assembly With Manual Release Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing slide rail assemblies often require a third rail or accessory to release the locking relationship between the second and first rails, which may not be suitable for all application environments or market requirements.
Innovation Solution
A slide rail assembly with a locking mechanism and an operating member that allows the second rail to be moved relative to the first rail without using the third rail, featuring a locking member, elastic member, and an operating member that manually switches the locking mechanism from a locking to a non-locking state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a third rail or accessory is used to release the locking relationship between the first and second rails, then the locking mechanism can be released, but the device complexity increases and it becomes unsuitable for environments with limited space
Solution Approach 1:
The patent extracts the release function from the third rail accessory and integrates it directly into the operating member. The operating member is movably connected to the second rail and directly actuates the locking member, eliminating the need for the third rail or accessory while maintaining the release functionality.
Solution Approach 2:
The operating member serves multiple functions: it controls the extension and retraction of the second rail relative to the first rail, and it directly releases the locking mechanism by actuating the locking member. This multi-functional design eliminates the need for separate third rail components.
2Ease of operation
If a third rail or accessory is used to release the locking relationship, then the locking can be released, but the device becomes unsuitable for environments with limited space
Solution Approach 1:
The patent removes the third rail accessory from the system and integrates its release function into the operating member, which is directly connected to the second rail. This reduction in components makes the device more adaptable to environments with limited space.
Solution Approach 2:
The operating member is designed to be movable relative to the second rail, allowing it to dynamically switch between locked and unlocked states. This dynamic design provides greater adaptability to different operational environments and space constraints.
3Device complexity
If the locking mechanism uses a locking member connected to the second rail, then the structure is simplified, but the ease of operation decreases without an accessible operating member
Solution Approach 1:
The operating member serves as an intermediary between the user and the locking member. It is movably connected to the second rail and transmits the user's manual operation to the locking member, making the locking mechanism both simple in structure and easy to operate.

Function Achieved in This Case
Enables the second rail to be retracted relative to the first rail without the third rail, providing flexibility and ease of use in various environments, including those with limited space.
Implementation Method 1
an elastic member configured to provide an elastic force to the locking member

AI summary
A slide rail assembly includes a first rail, a second rail, a third rail, a locking member and an operating member. The second rail is movable relative to the first rail between a first position and a second position. The third rail is movable relative to the second rail. The locking member is mounted to the second rail. When the second rail is located at the second position, the locking member is configured to lock a portion of the first rail, such that the second rail is not movable relative to the first rail from the second position toward the first position. The operating member is configured to be operated by a user to unlock the portion of the first rail from the locking member.
