Rotatable Adjusting Element for Drawer Closing Position Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for adjusting the closing position of drawers on furniture carcasses are complex and non-intuitive, leading to uneven front images when multiple drawers are stacked, as they often require precise alignment and cannot create a uniform flush or gap between the drawer fronts and the furniture body.
Innovation Solution
A device with a rotatable adjusting element and a linearly adjustable sliding element that can be attached to the carcass rail, allowing for intuitive depth adjustment of the drawer by turning the adjusting element, which limits the drawer's movement and creates a mechanically fixed stop for uniform alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If existing adjusting devices are used to set drawer closing positions, then the drawer depth can be adjusted, but the structure becomes complex and operation becomes non-intuitive
Solution Approach 1:
The adjusting device is segmented into distinct functional components: a stop element with a free end, a drawer rail with a counterstop, and an attachment mechanism. This segmentation allows each component to perform its specific function independently, simplifying the overall structure while maintaining adjustability. The stop element can be independently positioned along the carcass rail without requiring complex mechanical linkages.
Solution Approach 2:
The device enables self-service adjustment through the intuitive interaction between the stop's free end and the counterstop on the drawer rail. The user can directly manipulate the stop position without requiring additional tools or complex mechanisms. The mechanical stop-counterstop interaction provides automatic positioning and locking, eliminating the need for sophisticated adjustment mechanisms.
2Manufacturing precision
If existing adjusting devices are used, then drawer depth adjustment is possible, but the front image alignment becomes uneven across multiple drawers
Solution Approach 1:
The device creates equipotential alignment conditions by providing a standardized stop mechanism that can be uniformly attached to the carcass rail at different vertical positions. Each drawer equipped with this device achieves the same alignment reference point, ensuring that all drawer fronts align evenly with the furniture facade regardless of their vertical position. The simple stop-counterstop mechanism ensures consistent positioning across multiple drawers.
Solution Approach 2:
The adjusting device is designed as a universal component that can be applied to multiple drawers at different heights on the same carcass rail. The stop element with its free end and the counterstop mechanism work together in a standardized manner, allowing uniform adjustment and alignment across all drawers. This multi-drawer applicability ensures consistent front image alignment throughout the furniture piece.
3Ease of manufacture
If a simple attachment mechanism is used, then the device can be easily installed, but the closing position cannot be precisely controlled
Solution Approach 1:
The device enables precise control of the closing position parameter by allowing the stop's free end to be positioned at different locations along the carcass rail. The precision is achieved not through complex mechanisms but through the ability to vary the position parameter directly. The stop can be attached at any desired location, and the corresponding drawer closing position is precisely determined by the distance between the stop and the counterstop, providing accurate control without complicating the attachment mechanism.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables easy, intuitive depth adjustment of drawers, ensuring a uniform flush front image or predefined gap between drawer fronts and the furniture carcass, improving design aesthetics and functionality.
Implementation Method 1
the adjusting element of the device and a sliding element of the device coupled to the adjusting element are configured in such a manner that the sliding element is linearly adjustable by a turning movement of the adjusting element
Implementation Method 2
the stop or an outer side of the stop acts as a mechanically fixed stop for the counterstop in the closing position and blocks any further movement of the drawer rail in the closing direction

AI summary
A device is provided for adjusting a closing position of a drawer. The device is configured to be attached to a carcass rail such that the closing position of the drawer can be set with respect to a direction of movement of the drawer provided with the rail guide. The device includes a rotatable adjusting element and a stop. When the device is mounted on the furniture, the stop can be brought into different adjustment positions on the device by turning the adjusting element, and the stop predefines the closing position of the drawer. The adjusting element and a sliding element of the device, coupled to the adjusting element, are configured that the sliding element is linearly adjustable by a turning movement of the adjusting element, and the stop is provided on the sliding element.
