Solution Overview

Problem

Existing slide rail assemblies with four or more rails are not compatible with blocking mechanisms designed for limited environments, as they fail to efficiently manage rail movement and detachment in such spaces.

Innovation Solution

A slide rail assembly with a supporting frame, multiple rails, and working members featuring a blocking and positioning structure that allows for controlled movement and detachment of rails by switching states, enabling the assembly to adapt to different positions and facilitate detachment in limited environments.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If a blocking mechanism is used to prevent rail movement in limited environments, then space utilization is improved, but the mechanism becomes incompatible with slide rail assemblies having four or more rails

Engineering Contradiction:

Improvespace utilizationVSAvoidcompatibility with four or more rails

Core Design Contradiction:

Volume of moving objectVSAdaptability or versatility

Solution Approach 1:

The blocking function is segmented into multiple independent blocking members (first blocking member, second blocking member, third blocking member) that can independently control different rails. Each blocking member can be selectively activated or deactivated based on the number of rails in the assembly, allowing the mechanism to adapt from three-rail to four-or-more-rail configurations while maintaining space utilization benefits.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The blocking members are designed to be dynamically controllable through working members that can switch between blocked and unblocked states. This dynamic capability allows the system to adapt its blocking behavior based on the specific rail configuration, enabling compatibility with four or more rails while preserving the space-saving advantages in limited environments.

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If multiple working members are added to control rail movement in four-or-more-rail assemblies, then adaptability is improved, but device complexity increases

Engineering Contradiction:

Improvecompatibility with four or more railsVSAvoidnumber of working members

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Each working member is designed with multi-functionality to control multiple blocking members simultaneously. For example, the first working member can control both the first blocking member and the second blocking member, reducing the total number of working members needed while maintaining full adaptability across different rail configurations.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The control functions of multiple blocking members are merged into fewer working members. Instead of having separate working members for each blocking member, the patent combines control capabilities so that one working member can manage multiple blocking members, thereby reducing overall device complexity while preserving adaptability.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

A slide rail assembly includes a supporting frame, a first rail, a second rail and a third rail. The first rail is movable relative to the supporting frame. The second rail is movable relative to the first rail. The third rail is movable relative to the second rail, and the second rail is movably mounted between the first rail and the third rail. The first rail can be moved to a second predetermined position from a first predetermined position in a retracting direction relative the supporting frame. The first rail can be retained at the second predetermined position so as to shorten a length of the slide rail assembly such that the third rail can be detached from the second rail easily in a limited environment.
