Solution Overview

Problem

Existing slide rail assemblies are inadequate in supporting chassis with specifications other than 1U, such as 2U, due to insufficient supporting capability.

Innovation Solution

A slide rail assembly with a guide rail featuring a first rail section, a second rail section, and a third rail section, where the first rail section is bent relative to the second, and a path defined between the second and third sections to accommodate fixing members of varying chassis specifications, allowing for secure mounting and support of both 1U and 2U chassis.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a traditional slide rail assembly with a single rail configuration is used, then the structure is simple and easy to manufacture, but it cannot support chassis with specifications other than 1U

Engineering Contradiction:
Improvecompatibility with different chassis specificationsVSAvoidguide rail structure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The guide rail is divided into multiple rail sections (first rail section, second rail section, third rail section) with different configurations. Each section serves a specific function: the first rail section supports 1U chassis, the second rail section supports 2U chassis, and the third rail section provides additional support. This segmentation allows the single guide rail to accommodate multiple chassis specifications without requiring separate rail assemblies for each type.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If the guide rail is designed with multiple rail sections to support different chassis, then compatibility with various chassis specifications is achieved, but the manufacturing complexity increases

Engineering Contradiction:
Improvesupport for 1U and 2U chassisVSAvoidguide rail fabrication complexity
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

Multiple functional rail sections that would traditionally require separate manufacturing processes and assemblies are merged into a single integrated guide rail structure. The first, second, and third rail sections are combined in one continuous component, simplifying the overall manufacturing process while maintaining the ability to support different chassis specifications through the different sections.

Inventive Principle:
Principle #5Merging (Combining)

3Ease of operation

If a fixed rail configuration is used, then the manufacturing process is simple, but the mounting flexibility for different chassis dimensions is limited

Engineering Contradiction:
Improvemounting flexibilityVSAvoidrail section configuration
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

Different sections of the guide rail are designed with locally optimized characteristics tailored to specific chassis types. The first rail section has features optimized for 1U chassis mounting, the second rail section has features optimized for 2U chassis, and the third rail section provides additional localized support. This local quality approach allows each section to perform its specific function effectively while maintaining overall system simplicity.

Inventive Principle:
Principle #3Local quality
