Solution Overview

Problem

Existing reinforcement devices for slide assemblies increase the width of the rail assembly, making them unsuitable for installation in racks with limited space.

Innovation Solution

A reinforcement device with a rail featuring a recessed reinforcement path and a movable reinforcement member connected via an extension support, which narrows the width by integrating reinforcement without expanding the assembly's dimensions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If a reinforcing element is connected to the outer surface of the stationary rail and fixed to it, then the strength and stability of the slide assembly are improved, but the width of the assembly increases making it unsuitable for racks with limited space

Engineering Contradiction:
Improvestrength of slide assemblyVSAvoidwidth of slide assembly
Core Design Contradiction:
StrengthVSLength of stationary object

Solution Approach 1:

The reinforcement member is nested within a recessed reinforcement path formed in the sidewall of the rail. The recessed path has a depth that accommodates the thickness of the reinforcement member, allowing the reinforcement to be embedded within the existing width of the rail rather than adding to it. This nesting approach provides structural reinforcement while maintaining a compact width suitable for limited rack spaces.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

Instead of adding reinforcement in the horizontal dimension (which would increase width), the design transitions to the vertical dimension by creating a recessed path with depth. The reinforcement member is positioned within this depth, utilizing the third dimension (depth/thickness) to provide strengthening without affecting the critical width parameter.

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

2Strength

If the reinforcement path has sufficient depth to accommodate the reinforcement member, then the reinforcement effectiveness is improved, but the manufacturing complexity increases

Engineering Contradiction:
Improvereinforcement effectivenessVSAvoidmanufacturing complexity
Core Design Contradiction:
StrengthVSEase of manufacture

Solution Approach 1:

The reinforcement path is segmented into discrete sections along the rail, with each section having a defined depth and cross-sectional shape. The path includes a connection wall that divides the recessed area, creating separate compartments that can be manufactured using standard forming techniques. This segmentation allows the complex three-dimensional recessed structure to be produced through conventional manufacturing processes rather than requiring complex multi-step operations.

Inventive Principle:
Principle #1Segmentation

AI summary

A reinforcement device includes a rail (10), a reinforcement member (30) and an extension support (32) which is connected to the reinforcement member (30). The rail (10) has a top wall (12a), a bottom wall (12b) and a sidewall (14) connected between the top and bottom walls (12a, 12b). The sidewall (14) has a first face (16a) and a second face (16b) which is located opposite to the first face (16a). A space between the top wall (12a), the bottom wall (12b) and the first face (16a) of the sidewall (14) defines a slide path (18). The reinforcement member (30) is connected to the reinforcement path (20) of the rail (10). The extension support (32) is engaged with the rail (10). The rail (10) is reinforced by the reinforcement member (30) and the extension support (32).
