Coupling mechanism and slide rail assembly for furniture part
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing furniture slide rail systems lack efficient mechanisms for lateral and height adjustment of drawers within a cabinet, limiting user flexibility and precision in positioning furniture parts.
Innovation Solution
A coupling mechanism comprising a first base, a second base, a lateral adjustment member, and a transmission structure, along with a height adjustment member, which allows for lateral displacement and height adjustment of the second rail with respect to the first rail, enabling precise positioning of furniture parts through a spiral guide groove and threaded structures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional fixed slide rail system is used, then the structure is simple and reliable, but the drawer cannot be laterally adjusted or height-adjusted, limiting positioning flexibility
Solution Approach 1:
The coupling mechanism employs a nested structure where the second base is movably mounted on the first base, and the lateral adjustment member is rotatably mounted on one of the bases. The transmission structure converts rotary movement into lateral displacement within this nested arrangement, allowing multiple adjustment functions without requiring separate mechanisms.
Solution Approach 2:
The system transitions from a fixed rigid connection to a dynamic adjustable connection. The second base can be laterally displaced with respect to the first base through the transmission structure, and the supporting member can be height-adjusted with respect to the coupling base, enabling the drawer to adapt to different positioning requirements.
2Measurement precision
If manual lateral adjustment is implemented, then positioning flexibility is improved, but the adjustment precision and ease of operation are reduced
Solution Approach 1:
The patent replaces direct manual lateral adjustment with a transmission structure that converts rotary movement into precise lateral displacement. This mechanical substitution allows for more precise control and easier operation compared to direct manual positioning, as rotational movement can be more precisely controlled than linear positioning.
Solution Approach 2:
The system changes the adjustment parameter from direct linear displacement to rotational movement. By rotating the lateral adjustment member, the transmission structure converts this rotational parameter change into precise lateral displacement of the second base, improving both precision and ease of operation.
3Adaptability or versatility
If the slide rail assembly is mounted as an undermount hidden design, then aesthetics are improved, but access for adjustment and maintenance becomes more difficult
Solution Approach 1:
The coupling mechanism is designed as a segmented, modular assembly with distinct components (first base, second base, lateral adjustment member, transmission structure, supporting member, height adjustment member) that can be independently accessed and adjusted. This segmentation allows for easier maintenance and adjustment even in the undermount configuration.
Solution Approach 2:
The coupling mechanism acts as an intermediary between the fixed first base and the movable second base carrying the drawer. This intermediary structure provides accessible adjustment points while maintaining the hidden undermount aesthetic, as the adjustment members can be operated from the drawer side without exposing the mounting structure.
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
Enables easy lateral and height adjustment of furniture parts, improving user flexibility and precision in positioning, while maintaining a hidden undermount design, and compensating for potential gaps between the rail and drawer.
Implementation Method 1
The adjusting portion is a substantially spiral guide groove, and the transmission structure is a projection located in the guide groove
Implementation Method 2
The height adjustment member is rotatably mountable on the coupling base, and the height adjustment member and the supporting member include corresponding threaded structures

AI summary
A coupling mechanism adapted for a slide rail includes a first base, a second base, and an adjustment member. The slide rail includes a coupling base engaged with the first base. The second base is movably mounted on the first base. The adjustment member is configured for laterally displacing and thereby adjusting the second base with respect to the slide rail. More specifically, the adjustment member includes an adjusting portion, and one of the first base and the second base includes a transmission structure configured to work with the adjusting portion in order to convert a rotary movement of the adjustment member into a lateral displacement of the second base with respect to the slide rail.
