Furniture Guide Rail Attachment With Adjustable Bearing Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for attaching guide units to furniture parts often lack precise positioning capabilities and stability, leading to lateral clearance issues and inefficient assembly processes.
Innovation Solution
A device with adjustable bearing portions on a lower edge, allowing for alignment and secure attachment of a furniture part to a motion rail, which can be readjusted to accommodate various positions and widths of the rail, ensuring stable and precise positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If fixed bearing portions are used on the attachment device, then the structure is simple and easy to manufacture, but lateral clearance occurs and positioning precision deteriorates
Solution Approach 1:
The bearing portions are made adjustable rather than fixed, allowing the attachment device to adapt to different motion rail positions. The bearing portions can be repositioned along the attachment device to eliminate lateral clearance and achieve precise positioning, while maintaining a relatively simple overall structure.
2Manufacturing precision
If adjustable bearing portions are added to eliminate lateral clearance, then positioning precision is improved, but device complexity increases
Solution Approach 1:
The attachment device is divided into modular components, with bearing portions that can be independently adjusted. This segmentation allows the bearing portions to be positioned separately to eliminate lateral clearance without requiring complete redesign of the entire device structure.
3Manufacturing precision
If the attachment device is designed for precise positioning, then lateral clearance is reduced, but the assembly process becomes more time-consuming
Solution Approach 1:
The bearing portions are pre-configured to be adjustable, allowing for quick positioning during assembly. The adjustment mechanism is designed to enable rapid alignment and elimination of lateral clearance without requiring complex assembly procedures or excessive time investment.

AI summary
A device for attaching a guide unit to a first furniture part which is movably guided relative to a second furniture part, wherein the guide unit includes a basic unit rail disposed on the second furniture part and a motion rail disposed on the first furniture part. Two bearing portions are disposed spaced apart on a lower edge of the device, which is provided for disposal on the motion rail. Each of the bearing portions is configured on a side which faces the respective other bearing portion, such that the motion rail can be disposed between the bearing portions. At least one of the bearing portions is mounted on the device so as to be readjustable so that a position of the bearing portion is modifiable to align the first furniture part in the assembled state in a horizontal direction in relation to the motion rail.
