Coupling device for a drawer guide
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coupling devices for drawers and pull-out runners require separate designs for left and right-hand attachments, complicating assembly and manufacturing, and increasing handling effort.
Innovation Solution
A one-piece coupling part with a symmetrical design and actuating element that can pivot both longitudinal struts, allowing for easy manual operation and reduced force component requirements for latching and unlocking, along with an integrated height adjustment device for versatile attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate coupling devices are used for left and right-hand attachments, then the latching function is reliable, but the device complexity and manufacturing effort increase
Solution Approach 1:
The coupling device is designed with a symmetrical structure where the actuating element can pivot both longitudinal struts simultaneously, allowing the same device to function for both left-hand and right-hand attachments. This universal design eliminates the need for separate coupling devices for each side, reducing device complexity while maintaining reliable latching functionality.
2Reliability
If separate coupling devices are used for left and right-hand attachments, then the latching function is reliable, but the manufacturing effort increases
Solution Approach 1:
By designing a single universal coupling device with symmetrical structure and dual actuation capability, the manufacturing process is simplified. Instead of producing and inventorying separate left and right-hand coupling devices, only one type needs to be manufactured, significantly reducing manufacturing effort and complexity while ensuring consistent latching reliability.
3Reliability
If separate coupling devices are used for left and right-hand attachments, then the latching function is reliable, but the assembly effort increases
Solution Approach 1:
The universal coupling device can be installed on both left and right sides using the same orientation and procedure, eliminating the need for fitters to handle different device variants. This simplifies the assembly process, reduces training requirements, and increases productivity while maintaining the reliable latching function through the symmetrical design.
4Ease of operation
If the actuating element pivots both longitudinal struts, then the handling effort is reduced, but the structural complexity increases
Solution Approach 1:
The actuating element is designed as an integrated component that combines the function of pivoting both longitudinal struts into a single motion. This merging of functions into one actuating mechanism reduces handling effort, as the user operates a single element rather than two separate controls, while the symmetrical structure keeps the overall device complexity manageable.

AI summary
The invention relates to a device for coupling a drawer to a guide rail of a drawer slide, comprising a fastening means for attaching the device to the drawer, a locking element for locking the device to the guide rail, an actuating element for moving the locking element into a coupling position in which the locking element is locked to the guide rail, and into a non-coupling position in which the locking element is not connected to the guide rail, wherein the fastening means, the locking element and the actuating element are integrally connected to one another to form a single coupling part, the coupling part having two parallel longitudinal struts on the outside of each of which the locking element is integrally formed.that the longitudinal struts are integrally formed with a first end on a base element of the coupling part which includes the fastening means, and that the actuating element projects from the same on a side of the two longitudinal struts facing each other.
