Furniture Drawer Retracting Slide With Adjustable Closing Path
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drive devices for movable furniture parts face challenges in combining retracting and ejecting movements without hindering each other, particularly in adjusting the retracting path to accommodate different drawer sizes and weights, and in allowing for easy retrofitting of ejection devices without exchanging the entire retracting device.
Innovation Solution
The drive device allows for adjustable end positions along the guide path by using a movable slide part and a blocking device, enabling the retracting path to be changed mechanically, allowing for longer or shorter travel depending on the configuration, and enabling seamless integration with ejection devices for smooth operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the retracting path is shortened to accommodate small drawers, then the device fits smaller furniture parts, but drawers with larger weight may stop before reaching the closed position
Solution Approach 1:
The guide path is made adjustable between different length configurations, allowing the retracting path to be dynamically adapted to match the specific drawer size and weight requirements. This resolves the contradiction by enabling the system to switch between short and long retracting paths rather than being fixed at one length.
Solution Approach 2:
The physical parameter of guide path length is changed to accommodate different operating conditions. By providing multiple discrete length options, the system can optimize the retracting path length for each specific application, ensuring reliable closing for both small and large drawers.
2Adaptability or versatility
If the guide path length is fixed, then the device structure is simple, but it cannot adapt to different drawer sizes and weights
Solution Approach 1:
The guide path is divided into multiple discrete length configurations that can be selectively engaged. This segmentation allows the system to offer adaptability through multiple options while keeping each individual configuration relatively simple in structure.
Solution Approach 2:
The adjustable guide path mechanism serves multiple functions: it provides different retracting path lengths for different drawer sizes, maintains structural simplicity through a standardized adjustment mechanism, and enables universal application across various furniture types.
3Adaptability or versatility
If an ejection device is added to an existing retracting device, then the furniture part can be ejected automatically, but the entire retracting device must be exchanged
Solution Approach 1:
The retracting device is designed as a modular system where the guide path can be independently adjusted or replaced without affecting the entire device. This segmentation enables the ejection device to be added as a separate component while maintaining compatibility with the existing retracting mechanism.
Solution Approach 2:
The adjustable guide path provides the flexibility needed to accommodate the additional ejection device. By dynamically reconfiguring the guide path length and position, the system can integrate the ejection function without requiring complete device replacement.

AI summary
A driving device for a movable furniture part includes a retracting device for retracting the movable furniture part out of an open position into a close position, and the retracting device has a housing; a guide path formed in the housing and which comprises a retaining section; a retracting slide which can be moved in the guide path relative to the housing and can be locked in the retaining section; and a retracting force accumulator which urges the retracting slide. The retracting slide can be moved along the guide path between a first end position, which corresponds to the retaining section, and a second end position, which corresponds to the closed position, wherein the distance between the end positions along the guide path can be changed.
