Solution Overview

Problem

Existing slide rail assemblies lack flexibility in accommodating different user demands for drawer positioning and noise reduction, as they either require fixed positioning or fail to adjust for tolerance issues between the drawer and the cabinet.

Innovation Solution

A slide rail assembly with a fitting member, comprising a first rail, a second rail, a blocking structure, a base, and an adjusting device, where the adjusting device includes a mounting member and an adjusting member connected in an adjustable manner, allowing the second rail to be positioned at a single or multiple predetermined longitudinal positions by adjusting the length of the device, and the fitting member can be either a blocking member for noise reduction or an adjusting device for depth adjustment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If a fixed positioning structure is used in the slide rail assembly, then the drawer can be located at a same position when retracted, but the assembly cannot accommodate tolerance variations or adjust to different positioning requirements

Engineering Contradiction:
Improvedrawer positioning precisionVSAvoidposition adjustment capability
Core Design Contradiction:
Manufacturing precisionVSAdaptability or versatility

Solution Approach 1:

The patent applies the dynamics principle by implementing an adjustable positioning mechanism that allows the drawer to be located at different longitudinal positions. The adjusting member can be positioned at multiple locations along the adjusting device, enabling dynamic repositioning of the drawer relative to the cabinet to accommodate both precision requirements and tolerance variations.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent applies parameter changes by providing an adjusting device with multiple predetermined positions that can change the longitudinal position of the drawer. By selecting different positions of the adjusting member, the system can adjust key dimensional parameters such as the depth between drawer and cabinet, thereby adapting to different positioning requirements and tolerance conditions.

Inventive Principle:
Principle #35Parameter changes

2Adaptability or versatility

If an adjusting mechanism with multiple positions is provided, then the drawer can be located at different positions to accommodate tolerance issues, but the structure becomes more complex

Engineering Contradiction:
Improveposition adjustment capabilityVSAvoidadjusting mechanism complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies segmentation by dividing the adjusting device into distinct modular components: a mounting member fixed to the slide rail assembly, an adjusting member with multiple positioning locations, and connection elements. This segmented design allows for easier manufacturing, assembly, and maintenance while providing multiple adjustable positions through the modular structure.

Inventive Principle:
Principle #1Segmentation

3Object-affected harmful factors

If a blocking structure is added to prevent noise during retraction, then noise is reduced, but the positioning flexibility is compromised

Engineering Contradiction:
Improvenoise during drawer retractionVSAvoidposition adjustment capability
Core Design Contradiction:
Object-affected harmful factorsVSAdaptability or versatility

Solution Approach 1:

The patent applies the intermediary principle by introducing a fitting member as a mediator between the blocking structure and the adjusting mechanism. This fitting member can be selectively positioned or configured to provide noise reduction through the blocking structure while allowing the adjusting member to maintain its position adjustment capability, thus mediating between noise control and positioning flexibility requirements.

Inventive Principle:
Principle #24Intermediary (Mediator)

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 enables the second rail to be precisely positioned at desired locations relative to the first rail, either maintaining a fixed position for noise reduction or adjusting to accommodate different depths, effectively addressing user demands for flexibility and tolerance issues.

Implementation Method 1

The mounting member comprises a first threaded feature. The mounting member and the adjusting member are connected to each other in an adjustable manner, so that the position of the adjusting member may be adjusted relative to the mounting member such that the longitudinal length of the adjusting device is adjustable

AI summary

A slide rail assembly (20) is disclosed and includes a first rail (22), a second rail (24) and a fitting member. The second rail (24) and the first rail (22) are movable relative to each other. The fitting member is detachably mounted to one of the first rail (22) and the second rail (24). The fitting member is configured to block the second rail (24) as a blocking member (30), such that the second rail (24) is located at a same position when retracted relative to the first rail (22). Alternatively, the fitting member is configured to adjust the position of the second rail (24) as an adjusting device (44), such that the second rail (24) can be located at different positions in response to the adjustment of the adjusting device (44) when retracted relative to the first rail (22).
