Solution Overview

Problem

Existing slide rail structures lack sufficient strength to support overweight objects and may deform under external forces or collisions, necessitating an enhancement in structural integrity.

Innovation Solution

A reinforced slide rail assembly featuring a first rail with a passage and a second rail that is movable, along with a reinforcing structure comprising bent sections and an engaging mechanism, which includes a bracket device with a mounting feature and connecting features to improve stability and structural strength.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If a conventional slide rail structure is used, then the structure is simple and easy to manufacture, but the structural strength is insufficient to support overweight objects

Engineering Contradiction:
Improvestructural strengthVSAvoidstructure complexity
Core Design Contradiction:
StrengthVSDevice complexity

Solution Approach 1:

The second rail is divided into a first section and a second section connected through a bending section. This segmentation allows the rail to be optimized for different functions: the first section for mounting into the passage and the second section for providing engagement surfaces, thereby increasing structural strength without excessive complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The reinforcing structure extends from the first section through the bending section to the second section, adding a dimensional element that reinforces the rail structure. This additional structural dimension provides extra support points and increases overall strength to handle overweight objects.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Reliability

If the slide rail structure is simplified, then the manufacturing is easier, but the slide rail may deform under external forces or collisions

Engineering Contradiction:
Improveresistance to deformationVSAvoidmanufacturing complexity
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The bending section is strategically positioned at a critical location where reinforcement is most needed to prevent deformation under external forces or collisions. This localized quality enhancement provides resistance to deformation without requiring the entire structure to be overly complex.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The reinforcing structure with its bending section is pre-configured in the second rail before assembly, providing built-in resistance to deformation. This preliminary structural preparation ensures the rail can withstand external forces and collisions without requiring complex post-assembly reinforcement.

Inventive Principle:
Principle #10Preliminary action

3Strength

If a reinforced structure is added to the second rail, then the structural strength is improved, but the device complexity increases

Engineering Contradiction:
Improvestructural strengthVSAvoidcomponent quantity
Core Design Contradiction:
StrengthVSDevice complexity

Solution Approach 1:

The reinforcing structure is merged with the second rail as an integrated component rather than a separate attachment. The first section, bending section, and second section form a unified structure that provides reinforcement while minimizing the number of discrete parts, thus reducing overall device complexity.

Inventive Principle:
Principle #5Merging (Combining)
