Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing power supply devices for pull-out elements, such as drawers or trays, are not compatible with drive devices that influence the movement of the pull-out guide due to the placement of the cable guide preventing the attachment of a drive device.

Innovation Solution

A power supply device that integrates a detachable cable guide and driver as a common structural unit, allowing the cable guide to be offset from the drive device, with the interface of the pull-out guide serving dual functions for attachment and cable routing, enabling a space-saving and cost-effective design compatible with drive devices.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If the cable guide is integrated into the pull-out guide structure, then cable routing is enabled, but the attachment of drive devices is prevented

Engineering Contradiction:

Improvecable routing integrationVSAvoiddrive device attachment

Core Design Contradiction:

Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The driver is separated from the cable guide, allowing the driver to be detachably fastened to the pull-out guide while the cable guide remains integrated. This segmentation enables both cable routing and drive device attachment without interference.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The interface of the pull-out guide is designed to serve dual functions: attaching the driver and routing the cable guide. This multi-functionality eliminates the need for separate attachment points while maintaining both cable routing and drive device compatibility.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Ease of manufacture

If a separate interface for cable routing is added to the pull-out guide, then cable routing is enabled, but the device complexity increases

Engineering Contradiction:

Improvecable routing capabilityVSAvoidinterface quantity

Core Design Contradiction:

Ease of manufactureVSDevice complexity

Solution Approach 1:

The existing interface of the pull-out guide is made multi-functional to serve both as an attachment point for the driver and as a routing path for the cable guide. This eliminates the need for additional separate interfaces, maintaining device simplicity while enabling cable routing.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The cable guide attachment and driver attachment functions are merged into a single interface structure of the pull-out guide, reducing the total number of components and interfaces while achieving both functions simultaneously.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

A power supply device includes a pull-out guide for movably mounting the pull-out element on a furniture body. The pull-out guide has a body rail mounted on the furniture body, and a drawer rail to be connected to the pull-out element and movable relative to the body rail. A power outlet device is to be connected to the pull-out element, and a cable guide is to be connected to the pull-out guide. The pull-out guide or the pull-out element is connected to a drive device to drive the drawer rail or the pull-out element. A driver detachably fastened to the pull-out guide by an interface to cooperate with the drive device to transmit a force from the drive device to the pull-out guide or the pull-out element. The cable guide and the driver form a common structural unit to be detachably fastened to the interface of the pull-out guide.
