Solution Overview

Problem

Existing slide rail systems are limited to vertical installations and do not accommodate diverse operation demands, such as preventing adjacent drawers from being pulled out simultaneously.

Innovation Solution

A slide rail system with a working member and driving members that allow for longitudinal shifting, enabling the system to switch modes and prevent adjacent drawers from being pulled out by blocking the movement of corresponding rails.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a linkage mechanism is designed for vertical cabinet installation, then the anti-tilt function is achieved, but the system cannot accommodate diverse operation demands such as preventing adjacent drawers from being pulled out simultaneously

Engineering Contradiction:
Improveoperation demandsVSAvoidlinkage mechanism
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The working member is designed to perform multiple functions: it acts as a blocking member to prevent adjacent drawers from being pulled out simultaneously, and also serves as a driving member to drive the fourth rail when the second rail is pulled. This multi-functionality resolves the contradiction by enabling diverse operation demands without proportionally increasing device complexity

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The working member acts as an intermediary between the first slide rail assembly and the second slide rail assembly. It receives the pulling force from the second rail and transmits it to block the fourth rail, enabling the linkage function between adjacent drawers while maintaining a relatively simple mechanical structure

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If the second rail is pulled out from the first rail, then the drawer can be accessed, but the adjacent drawer on the second side cannot be pulled out due to the blocking mechanism

Engineering Contradiction:
Improvedrawer accessVSAvoidsimultaneous operation
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The working member is positioned in advance to block the fourth rail when the second rail is pulled out. This preliminary blocking action prevents the adjacent drawer from being pulled out simultaneously, ensuring that only one drawer can be accessed at a time while maintaining ease of operation for individual drawer access

Inventive Principle:
Principle #9Preliminary anti-action

AI summary

A slide rail mechanism is configured to a cabinet (22). The cabinet (22) includes a wall (38) with a first side (S 1) and a second side (S2) opposite to the first side (S 1). The slide rail mechanism includes a first slide rail assembly (26), a second slide rail assembly (28) and a working member (40). When a second rail (56) of the first slide rail assembly (26) is opened with respect to a first rail (54), the second rail (56) is able to drive the working member (40) for preventing a fourth rail (60) of the second slide rail assembly (28) to be opened with respect to a third rail (58).
