Single-Arm Furniture Drive With Adjustable Opening Stop
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing furniture drives require multiple levers to adjust the maximum opening angle of the actuating arm, leading to increased component count and material consumption, and are not suitable for drives with a single actuating arm.
Innovation Solution
A pivoting member is used to adjust the spacing of the actuating arm relative to an abutment on the carrier, allowing for intuitive adjustment of the maximum opening position without the need for additional supporting elements, reducing the number of components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple levers are used to adjust the maximum opening angle of the actuating arm, then the adjustment function is achieved, but the component count and material consumption increase
Solution Approach 1:
The patent combines the adjustment device with the actuating arm itself by integrating a pivoting member that can be moved relative to the actuating arm. This integration eliminates the need for separate supporting elements and reduces the overall component count while maintaining the maximum opening angle adjustment function.
Solution Approach 2:
The pivoting member serves multiple functions: it acts as both the adjustment mechanism and part of the actuating arm structure. By making the actuating arm itself adjustable through the pivoting member, the design achieves multi-functionality without adding extra components.
2Adaptability or versatility
If multiple levers are used to adjust the maximum opening angle, then the adjustment function is achieved, but material consumption increases
Solution Approach 1:
By merging the adjustment device with the actuating arm structure through the pivoting member, the patent eliminates redundant components that would consume additional materials. The integration reduces material consumption while preserving the full adjustment functionality.
3Device complexity
If the furniture drive is designed for a single actuating arm, then the structure is simplified, but existing adjustment devices cannot be applied
Solution Approach 1:
The patent introduces a dynamic pivoting member that can be moved to different positions relative to the actuating arm. This dynamic element enables the single actuating arm structure to achieve adjustable maximum opening angles, making it compatible with adjustment device requirements while maintaining structural simplicity.
Solution Approach 2:
The adjustment functionality is merged directly into the single actuating arm through the pivoting member, eliminating the need for separate supporting elements. This integration allows the simplified single-arm structure to be compatible with adjustment device requirements.

AI summary
A furniture drive for moving a furniture part movably supported relative to a furniture carcass. The furniture drive includes a carrier to be fixed to the furniture carcass, an actuating arm pivotally supported relative to the carrier about a pivoting axis between a closed position and a maximum opening position, and an adjustment device configured to adjust a position of the maximum opening position of the at least one actuating arm. The adjustment device includes a pivoting member configured to be moved in at least two pivoting positions relative to the actuating arm, and the pivoting member is configured to distance the actuating arm in the at least two pivoting positions to a different extent from an abutment arranged on the carrier when the actuating arm is arranged in the maximum opening position.
