Drive device for a moveable furniture part
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drive devices for moveable furniture parts, such as drawers, are relatively wide due to the placement of synchronization teeth and ejection force storage means laterally beside the guide track, making them inefficient in terms of space usage and component count.
Innovation Solution
The drive device is designed to have the synchronization coupling element and ejection force storage means arranged within the maximum guide track width, ensuring they do not project beyond it, allowing for a narrower structure with these components positioned either above, below, or behind the guide track, and the transmission element is preferably linearly moveable within the guide track.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the synchronization teeth and ejection force storage means are arranged laterally beside the guide track, then the drive device achieves proper synchronization and ejection functions, but the drive device becomes relatively wide and occupies more space
Solution Approach 1:
The patent applies dimensionality change by moving the synchronization coupling element and ejection force storage means from a lateral arrangement (beside the guide track) to a longitudinal arrangement (within the guide track width). This repositioning transforms the spatial configuration from a side-by-side layout to an integrated layout where components are arranged along the length of the guide track rather than extending its width, thereby resolving the contradiction between functional reliability and compact dimensions
2Area of stationary object
If the synchronization coupling element and ejection force storage means are arranged within the maximum guide track width, then the drive device becomes narrower and more compact, but the structural complexity increases
Solution Approach 1:
The patent applies merging by integrating the synchronization coupling element and ejection force storage means within the same spatial envelope defined by the guide track width. Instead of treating these as separate lateral components, the invention combines them into a unified arrangement where both elements share the longitudinal space along the guide track, reducing overall device width while managing complexity through functional integration
3Area of stationary object
If the transmission element is linearly moveable within the guide track, then the drive device achieves compact dimensions, but the manufacturing precision requirements increase
Solution Approach 1:
The patent applies the intermediary principle by using the guide track itself as a precision-guided intermediary structure. The guide track serves as a predefined pathway that constrains and guides the linear movement of the transmission element, thereby providing the necessary manufacturing precision through the track's geometric definition rather than requiring high-precision machining of the transmission element's movement surfaces

Function Achieved in This Case
This configuration results in a more compact and simplified drive device that takes up less space, with the option to be used individually or synchronized with another drive device, facilitating production and storage by maintaining a narrow design.
Implementation Method 1
an ejection force storage means (42) fixed on the one hand to the carrier (3) and on the other hand to the ejection slide (41)

AI summary
A drive device includes a carrier extending in the closing direction of a moveable furniture part, an ejection device for ejecting the moveable furniture part into an open position, and a locking device for locking the ejection device in a locked position. The locking device has a locking pin connected to the ejection device and a guide track for the locking pin formed in or on the carrier, and a synchronization device for synchronizing the movement of the drive device with a second drive device. The synchronization device has a transmission element moveably mounted on the carrier to be moved by the locking pin, and a synchronization coupling element connected to the transmission element. The guide track has a maximum guide track width measured perpendicular to the closing direction, and the synchronization coupling element and the ejection force store are arranged within this guide track width in the closing direction.
