Solution Overview

Problem

Existing drawer systems are not versatile enough to accommodate different types of drawer systems on a pull-out guide, limiting their adaptability and functionality.

Innovation Solution

A thrust system with first and second fastening means on the pull-out guide, allowing for the attachment of different drawer systems by providing multiple attachment options, including clip-on assemblies, sliding connections, and underfloor configurations, enabling various drawer systems to be mounted on the same rail.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a single type of connecting means is provided on the pull-out guide, then the structure is simple and easy to manufacture, but only a single drawer system can be mounted on the pull-out guide

Engineering Contradiction:
Improveability to mount different drawer systemsVSAvoidnumber of fastening means on pull-out guide
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The pull-out guide is designed with multiple fastening means (first fastening means and second fastening means) that can accommodate different types of drawer systems. The first fastening means is designed for drawers with clip-on assemblies, while the second fastening means is designed for drawers with connecting means arranged on the frame. This multi-functional design allows a single pull-out guide to support various drawer configurations, thereby resolving the contradiction between versatility and structural simplicity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If connecting means are precisely matched to the coupling outer part, then the attachment is reliable and secure, but it is not possible to fix different drawer systems on the pull-out runner

Engineering Contradiction:
Improvecompatibility with different drawer typesVSAvoidsecure attachment of drawer
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

Different regions of the pull-out guide are equipped with different fastening means tailored to specific drawer types. The first fastening means (such as an adapter with a hollow body section) is optimized for clip-on assemblies, while the second fastening means (such as a coupling unit) is optimized for connecting means on the frame. Each fastening means provides reliable attachment for its intended drawer type, while the overall system achieves versatility through this localized differentiation.

Inventive Principle:
Principle #3Local quality

3Adaptability or versatility

If an open longitudinal slot is provided at the front end of the running rail, then the drawer can be easily fixed and dismantled, but only a single drawer system can be mounted on the pull-out guide

Engineering Contradiction:
Improvenumber of drawer systems that can be mountedVSAvoidsimplicity of attachment and dismantling
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The pull-out guide is segmented into multiple functional zones with different fastening means. The first fastening means accommodates drawers with clip-on assemblies, while the second fastening means accommodates drawers with connecting means on the frame. This segmentation allows multiple different drawer systems to be mounted on the same pull-out guide, resolving the limitation of single-drawer configurations while maintaining ease of operation through standardized attachment mechanisms.

Inventive Principle:
Principle #1Segmentation

AI summary

The invention relates to a pull-out guide (8) comprising at least two rails that can be moved in relation to each other, wherein a first attaching means for attaching a pushing element of a first drawer system (3) is provided on a movable rail (10). A second attaching means at a distance from the first attaching means is provided on the movable rail (10) for attaching a pushing element of a second drawer system (52), and either a pushing element of a first or a second drawer system (3, 52) can be attached to the movable rail (10). By providing first and second attaching means on the movable rail (10), the pull-out guide (8) can be used in many ways and different drawer systems can be mounted on the movable rails (10).
