Solution Overview
Problem
Existing slide rail assemblies are not suitable for cabinet-type racks and have limited supporting capabilities due to their fixed design, which restricts their application and stability in mounting chassis.
Innovation Solution
A slide rail assembly comprising a first rail, a second rail movable along a longitudinal direction, and a guiding base with specific transverse widths and features, including an elastic member, guiding sections, and a blocking member, allowing for secure and rapid mounting and detachment of a chassis to a rack.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a fixed rail design is used, then the mounting speed is fast, but the supporting capability is limited
Solution Approach 1:
The patent applies the dynamics principle by making the second rail movable relative to the first rail along the longitudinal direction. This dynamic structure allows the slide rail assembly to adapt to different chassis sizes and weights, improving supporting capability while maintaining fast mounting speed. The movable second rail can extend or retract to provide appropriate support for different loading conditions.
2Device complexity
If a fixed rail design is used, then the structure is simple, but the adaptability to different rack types is poor
Solution Approach 1:
The movable second rail enables the slide rail assembly to adapt to different rack types including cabinet-type racks, while maintaining relatively simple structure. The mobility of the second rail allows adjustment to accommodate various installation environments and rack configurations.
Solution Approach 2:
The slide rail assembly is divided into multiple independent components: first rail, second rail, guiding base, connecting members, and elastic members. This segmentation allows each component to perform its specific function and enables flexible combination for different application scenarios, improving adaptability without significantly increasing overall structural complexity.
3Reliability
If the second rail is made movable, then the supporting capability is improved, but the device complexity increases
Solution Approach 1:
The assembly is segmented into modular components (first rail, second rail, guiding base, connecting members, elastic members) that can be independently manufactured and assembled. This modularity simplifies the manufacturing process and maintenance while achieving improved supporting capability through the movable second rail.
Solution Approach 2:
Connecting members and elastic members serve as intermediaries between the first rail and second rail, enabling the movable connection in a simple and reliable manner. These intermediary components facilitate the relative movement while maintaining structural integrity, improving supporting capability without excessive complexity.
4Manufacturing precision
If guiding sections with different widths are used, then the guiding precision is improved, but the manufacturing complexity increases
Solution Approach 1:
The guiding base features local quality variation with different sections having different transverse widths. The first guiding section has a first transverse width while the second guiding section has a second transverse width, allowing optimized guiding precision for different stages of chassis insertion without requiring complex manufacturing processes throughout the entire structure.

AI summary
A slide rail assembly is configured to mount a chassis to a rack. A plurality of mounting members are arranged at one side of the chassis. The slide rail assembly includes a first rail, a second rail and a guiding base. The second rail includes a side wall and a bottom wall. The guiding base is disposed at a front end of the second rail. The guiding base defines an entry, an exit and a passage located between the entry and the exit. The second rail is moved out of the rack relative to the first rail. The bottom wall of the second rail abuts against a bottom part of the chassis for pushing the chassis into the rack. The chassis is mounted to the second rail through guiding the plurality of mounting members by the entry to pass through the passage and the exit.
