Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing slide rail assemblies are not adaptable to varying user needs, particularly in narrow spaces, as they lack the ability to adjust length effectively to accommodate different environments and applications.
Innovation Solution
A slide rail assembly comprising a first rail, a second rail, and a working member, where the second rail can be longitudinally displaced to reach a predetermined position, with stops and elastic structures preventing displacement in both opening and retracting directions, allowing the assembly to change length based on user requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the slide rail assembly uses a fixed length design, then the structure is simple and easy to manufacture, but it cannot adapt to different environments and user needs
Solution Approach 1:
The slide rail assembly incorporates a movable second rail that can be positioned at different locations along the first rail, transforming a static fixed-length structure into a dynamic adjustable-length structure. This allows the assembly to adapt to different environmental requirements while maintaining a relatively simple overall design
Solution Approach 2:
The slide rail assembly is divided into multiple segments (first rail, second rail, working member) that can move independently relative to each other. The second rail can be positioned at different segments along the first rail, enabling length adjustment without requiring complete redesign of the entire structure
2Ease of operation
If the second rail is allowed to move freely along the first rail, then the assembly is easy to operate, but unintended displacement occurs preventing stable positioning
Solution Approach 1:
The working member automatically engages with the first stop when the second rail reaches the predetermined position, without requiring external intervention. The elastic structure provides automatic resetting functionality, creating a self-service positioning and resetting mechanism that maintains both ease of operation and position stability
Solution Approach 2:
The first stop is pre-positioned on the first rail to prevent the second rail from moving beyond the predetermined position. This preliminary blocking action counteracts any force that might cause unintended displacement, ensuring position stability while allowing free movement within the permitted range
3Adaptability or versatility
If the slide rail assembly is designed for extended position only, then the structure is simplified, but it cannot accommodate narrow spaces
Solution Approach 1:
The second rail is designed to be movable along the first rail, enabling the assembly to dynamically change its effective length. This allows the same assembly to accommodate both extended positions for large spaces and retracted positions for narrow spaces, providing versatility without requiring multiple different assembly designs
Solution Approach 2:
The effective length parameter of the slide rail assembly can be changed by positioning the second rail at different locations along the first rail. This parameter adjustment capability allows the assembly to adapt to different space requirements, from narrow spaces to extended configurations

AI summary
A slide rail assembly includes a first rail, a second rail, a stop, and a working member. The second rail can be displaced with respect to the first rail. The stop is disposed on the first rail. The working member is movably mounted on the second rail. When reaching a predetermined position after being displaced with respect to the first rail from an extended position in a retracting direction, the second rail is blocked by the stop via the working member and is thus prevented from being displaced from the predetermined position in an opening direction. The slide rail assembly has a shorter length when the second rail is at the predetermined position than when the second rail is at the extended position.
