Solution Overview

Problem

Existing pull-out guides for displaceable arrangements are cumbersome to install due to the separate arrangement of functional devices, which increases installation effort and complexity.

Innovation Solution

The pull-out guide incorporates receiving elements on the guide rails, allowing functional devices to be integrated directly onto the guide rails before assembly, thereby simplifying installation and achieving a compact design.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If functional devices are arranged separately from the pull-out guide on the body or pull-out, then the pull-out guide structure remains simple, but the installation effort and complexity increase

Engineering Contradiction:
Improveinstallation effortVSAvoidpull-out guide structure
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The patent combines the functional device (damping device or self-closing device) with the pull-out guide by providing a receiving element on the guide rail that accommodates the functional device. This integration allows both components to be installed together as a single unit, eliminating the need for separate installation of the functional device on the body or pull-out, thereby reducing installation effort and complexity while maintaining a unified structural design.

Inventive Principle:
Principle #5Merging (Combining)

2Ease of manufacture

If functional devices are integrated onto the guide rails, then installation effort is reduced, but the space requirements and compactness are affected

Engineering Contradiction:
Improveinstallation effortVSAvoidspace requirements
Core Design Contradiction:
Ease of manufactureVSVolume of moving object

Solution Approach 1:

The functional device is nested within a receiving element that is formed as an integral part of the guide rail structure. The receiving element creates a recess or cavity in the guide rail that accommodates the functional device, allowing the functional device to be housed within the existing structural envelope of the pull-out guide rather than adding external bulk, thus maintaining compactness while enabling integrated installation.

Inventive Principle:
Principle #7Nested doll (Nesting)

3Stability of the object's composition

If multiple C-shaped guide rails are arranged with backs facing away from one another, then the structural stability is improved, but the arrangement complexity increases

Engineering Contradiction:
Improveguide rail arrangement stabilityVSAvoidguide rail arrangement
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The pull-out guide is segmented into multiple independent C-shaped guide rails with their backs facing away from one another, allowing each guide rail to be manufactured and assembled separately. This segmentation provides structural stability through the distributed C-shaped configuration while simplifying the overall arrangement by enabling modular assembly of the guide rails with rolling elements, reducing the complexity of creating a monolithic structure.

Inventive Principle:
Principle #1Segmentation
