Slide rail assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing slide rail assemblies for furniture systems lack flexibility to accommodate user demands for consistent or adjustable drawer positioning, as they do not effectively address length tolerances and noise reduction between the drawer and cabinet.
Innovation Solution
A slide rail assembly comprising a first rail, a second rail, a blocking structure, and a fitting member, where the fitting member is detachably mounted to allow the second rail to be positioned at a single or multiple predetermined positions relative to the first rail, using a blocking member or an adjustable device to abut against the blocking structure, enabling consistent or adjustable depth settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed mounting structure is used for the slide rail assembly, then the manufacturing and installation process is simple, but the drawer position cannot be adjusted to accommodate tolerance variations and different user demands
Solution Approach 1:
The mounting structure is designed to be dynamically adjustable rather than fixed. The base includes multiple through-holes arranged in different positions, allowing the fitting member to be mounted at various locations. This enables the drawer position to be adjusted according to tolerance variations and user demands, while maintaining a relatively simple overall structure.
Solution Approach 2:
The base is segmented with multiple through-holes at different positions, allowing selective mounting of the fitting member. This segmentation provides adjustability without requiring a completely complex reconfigurable structure, as each hole represents a discrete adjustment option.
2Manufacturing precision
If the second rail is allowed to move freely relative to the first rail, then the ease of operation is improved, but the positioning precision and noise control deteriorate due to tolerance accumulation
Solution Approach 1:
The fitting member with blocking structure is pre-installed on the base before final assembly. This preliminary action establishes the positioning constraint in advance, ensuring that when the second rail is moved into its retracted position, it will be precisely stopped at the predetermined location by the blocking member, eliminating tolerance accumulation while maintaining smooth operation.
Solution Approach 2:
The blocking structure on the fitting member acts as an intermediary element between the first and second rails. It provides a controlled stopping point that mediates the movement between the two rails, ensuring precise positioning without requiring complex mechanical constraints that would hinder operation.
3Reliability
If the blocking structure is fixed on the rail, then the positioning stability is improved, but the ability to accommodate different user demands for different positions is reduced
Solution Approach 1:
The blocking structure's position is made dynamically configurable rather than fixed. The fitting member can be detached and re-mounted at different through-holes on the base, allowing the blocking position to be changed according to user demands. This maintains positioning stability during use while providing flexibility for reconfiguration.
Solution Approach 2:
The fitting member with blocking structure can be discarded from its current position and recovered at a different position on the base. This allows the blocking structure to be relocated to accommodate different user demands while maintaining its stabilizing function at each position.

AI summary
A slide rail assembly is disclosed and includes a first rail, a second rail and a fitting member. The second rail and the first rails are movable relative to each other. The fitting member is detachably mounted to one of the first rail and the second rail. The fitting member is configured to block the second rail as a blocking member, such that the second rail is located at a same position when retracted relative to the first rail. Alternatively, the fitting member is configured to adjust the position of the second rail as an adjusting device, such that the second rail can be located at different positions in response to the adjustment of the adjusting device when retracted relative to the first rail.
