Solution Overview

Problem

Existing slide rail mechanisms face limitations in adjustability and structural strength, particularly when carrying overweight objects, leading to tilting issues due to inadequate supporting frames and fixed reinforcing members.

Innovation Solution

The slide rail mechanism incorporates an auxiliary supporting frame, an extension supporting frame, and a reinforcing member, allowing for adjustable mounting and improved structural strength through movable components and supporting protrusions, enabling easy one-man operation and secure attachment to rack posts.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If a fixed reinforcing member is used to support the rail member, then the structural strength is improved, but the adjustability and ease of operation are reduced

Engineering Contradiction:
Improvestructural strengthVSAvoidadjustability
Core Design Contradiction:
StrengthVSEase of operation

Solution Approach 1:

The reinforcing member is designed to be movable relative to the rail member, transitioning between a first position for supporting the rail member and a second position for disengagement. This dynamic configuration allows the system to switch between providing structural strength and enabling ease of operation, resolving the contradiction between fixed strength and adjustability.

Inventive Principle:
Principle #15Dynamics

2Reliability

If the outer rail is made long enough to lock/release the rear slide rail mounting frame, then the locking reliability is improved, but the device complexity and space requirement increase

Engineering Contradiction:
Improvelocking reliabilityVSAvoidouter rail length
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The bracket device is nested within the supporting frame, which itself is movable within the slide rail mechanism. This nested configuration allows the locking function to be achieved through the coordinated movement of multiple compact components rather than requiring a single long outer rail, thereby maintaining locking reliability while reducing overall device complexity and space requirements.

Inventive Principle:
Principle #7Nested doll (Nesting)

3Weight of moving object

If the supporting frames are pulled down to accommodate overweight objects, then the load capacity is improved, but the tilting stability deteriorates

Engineering Contradiction:
Improveload capacityVSAvoidtilting stability
Core Design Contradiction:
Weight of moving objectVSStability of the object's composition

Solution Approach 1:

The bracket device is pre-configured with the reinforcing member positioned to support the rail member before the overweight object is placed. This preliminary positioning ensures that the structural strength is already in place to handle the load, preventing the supporting frames from being pulled down and maintaining tilting stability even when carrying heavy weights.

Inventive Principle:
Principle #10Preliminary action
