Detachable Slide Rail Assembly With Ball Retainer Blocking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing slide rail assemblies are not detachable, making them inconvenient to use and lacking in versatility for different operating methods.
Innovation Solution
A slide rail assembly with a ball retainer that includes a blocking base and a blocking member, allowing the second rail to be detached from the first rail by moving the blocking member from a first state to a second state, which enables the ball retainer to be moved along a direction, facilitating smooth movement and detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the ball retainer is mounted between the first rail and the second rail to assist smooth movement, then the movement smoothness is improved, but the rail assembly becomes non-detachable and inconvenient to use
Solution Approach 1:
The blocking member is designed to be movable between a blocking position (where it blocks the limiting part) and a non-blocking position (where it allows detachment). This dynamic element enables the rail assembly to switch between locked and detachable states, resolving the contradiction between maintaining smooth movement through the ball retainer and enabling ease of operation through detachability.
Solution Approach 2:
The blocking member acts as an intermediary element between the ball retainer and the limiting part. When positioned to block the limiting part, it prevents detachment while allowing the ball retainer to maintain smooth movement. When moved to the non-blocking position, it allows detachment. This intermediary mechanism reconciles the conflicting requirements of smooth movement and detachability.
2Stability of the object's composition
If the blocking member is configured to abut against the limiting part to prevent detachment, then the structural stability is improved, but the versatility for different operating methods is reduced
Solution Approach 1:
The blocking member's ability to change position between blocking and non-blocking states provides structural stability when needed while enabling operational versatility when required. This dynamic characteristic allows the same mechanism to serve multiple operating methods, resolving the contradiction between stability and adaptability.
Solution Approach 2:
The blocking member serves multiple functions: it provides structural stability by blocking the limiting part during normal operation, allows detachment when moved to the non-blocking position, and enables different operating methods. This multi-functionality resolves the contradiction between structural stability and operational versatility.
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
The solution allows for the smooth movement and detachment of the second rail from the first rail, enhancing usability and versatility by enabling the ball retainer to be driven to the front end of the first rail, thus providing better support and functionality.
Implementation Method 1
The ball retainer (60) is mounted between the outer slide member (24) and the inner slide member (26)... the ball retainer comprises a plurality of rolling members

AI summary
A slide rail assembly includes a first rail (20), a second rail (22), a blocking base (34), a ball retainer (24) and a blocking member (42). The blocking base (34) is arranged on the first rail (20) and has a limiting part (35). The ball retainer (24) is configured to assist the second rail (22) in moving relative to the first rail (20). The ball retainer (24) has a contact part (72). When the blocking member (42) is in a first state, the blocking member (42) is configured to push the contact part (72) to move the ball retainer (24) in response to a movement of the second rail (22) until the blocking member (42) abuts against the limiting part (35). When the blocking member (42) is in a second state, the blocking member (42) no longer abuts against the limiting part (35) of the blocking base (34).
