Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lockable ejector devices for furniture parts face issues with additional space requirements and inclined positioning of the front panel due to torsion bar coupling, which complicates maintenance and adjustment.
Innovation Solution
The use of a synchronization mechanism with movably coupled coupling elements and a stationarily arranged base element, featuring a synchronization unit that prevents inclined positioning and allows for easy adjustment of the front gap between the front panel and the furniture carcass, incorporating displacement devices and overload safety mechanisms for enhanced stability and user-friendly operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If two locking units are coupled together by a torsion bar, then the locking units are connected and can be operated simultaneously, but additional space is required in the depth of the article of furniture and the front panel tends to assume an inclined position
Solution Approach 1:
The coupling mechanism is divided into separate functional elements: a first coupling element connected to the first locking unit, a second coupling element connected to the second locking unit, and a synchronization unit that movably couples these two coupling elements. This segmentation allows each component to be optimized independently and reduces the overall space requirement compared to a single torsion bar coupling.
Solution Approach 2:
The synchronization unit acts as an intermediary mechanism between the two coupling elements. It movably couples the first and second coupling elements, enabling synchronized operation of the locking units while requiring less depth space than a direct torsion bar connection. The intermediary structure allows for compact arrangement within the furniture part.
2Stability of the object's composition
If two locking units are coupled together by a torsion bar, then the locking units are connected, but the front panel tends to assume an inclined position
Solution Approach 1:
The coupling system is segmented into distinct functional components that can be independently positioned and adjusted. The synchronization unit with its movable coupling elements allows for precise geometric arrangement that maintains the front panel in a substantially perpendicular position to the rear panel, avoiding the inclination problem caused by torsion bar coupling.
3Reliability
If the immobilization device and synchronization mechanism are arranged on the movable furniture part, then the device functions properly, but maintenance and adjustment become more difficult
Solution Approach 1:
The ejector device is divided into functionally independent modules: the immobilization device with locking units, the synchronization mechanism with coupling elements, and the force storage means. This segmentation allows each module to be independently accessed, maintained, and adjusted, improving serviceability while maintaining reliable functionality.
