Solution Overview

Problem

Existing slide rail assemblies face limitations in mounting and detaching due to length restrictions of the outer rail and lack of a stable locking mechanism that allows rotation of the hook when moving the slide rail assembly towards or away from the post.

Innovation Solution

A slide rail assembly with a rail element, a first bracket, a bracket device, and an extension element, where the bracket device includes a hook with a locking element that rotates when the assembly is moved, allowing easy detachment and mounting by disengaging the locking element from the second bracket, enabling the hook to pivot away from the close position.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a traditional locking mechanism with a floating pin is used, then the slide rail back mounting frame can be locked or released, but the design is limited by the length of the outer rail and the adjustment amount of the bracket

Engineering Contradiction:
Improvelocking mechanism stabilityVSAvoidadjustment range
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The locking element is designed to rotate between a locked position and an unlocked position, transforming a static locking mechanism into a dynamic one. This rotation allows the locking element to engage or disengage from the bracket's locking groove, providing reliable locking while enabling full adjustment range without being constrained by outer rail length

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The locking mechanism is divided into separate functional components: the locking element on the bracket, the corresponding locking groove, and the extension element on the slide rail. This segmentation allows independent optimization of each component, enabling the locking mechanism to provide stable locking while the extension element ensures sufficient adjustment range

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If the outer rail is made longer to enable full adjustment range, then the bracket can be adjusted freely, but the device complexity and material usage increase

Engineering Contradiction:
Improveadjustment rangeVSAvoidstructure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The adjustment function is segmented between the bracket with the locking mechanism and the extension element on the slide rail. The extension element provides the necessary travel distance for full adjustment, while the bracket with the rotating locking element provides the locking function. This segmentation eliminates the need for an excessively long outer rail, reducing overall device complexity

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The extension element acts as an intermediary between the slide rail and the bracket, providing the necessary extension for full adjustment range. This intermediary component allows the main slide rail to remain compact while still enabling the bracket to be adjusted across the full range of motion

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of manufacture

If a deformable latch member is used, then the bracket can be mounted to the post, but the latch member cannot stably mount the bracket

Engineering Contradiction:
Improvemounting simplicityVSAvoidmounting stability
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The locking element rotates from an unlocked position to a locked position, transitioning from a movable state to a fixed state. This dynamic locking mechanism provides both ease of mounting (simple rotation action) and high stability (positive engagement in the locking groove), resolving the contradiction between deformable latch simplicity and mounting stability

Inventive Principle:
Principle #15Dynamics

AI summary

A slide rail assembly (30) is configured to be detachably mounted to a first post (36) and a second post (38, 216) by a first bracket (32) and a bracket device (34, 200). The bracket device (34, 200) includes a second bracket (58, 206), a hook (62, 218), and a locking element (60, 202). The hook (62, 218) is connected to the second bracket (58, 206). The locking element (60, 202) is operatively engaged with the second bracket (58, 206) for abutting against the hook (62, 218) in order to hold the hook (62, 218) at a close position relative to the second post (38, 216). When the first bracket (32) is detached from the first post (36), and the locking element (60, 202) is operatively disengaged from the second bracket (58, 206), the locking element (60, 202) no longer abuts against the hook (62, 218).
