Drawer Guide Adjustment Mechanism for Vertical and Inclination Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing furniture designs face challenges in achieving flexible and simple adjustments of movable furniture parts relative to the movement rail, particularly in terms of vertical and inclination adjustments, often due to component and installation tolerances.
Innovation Solution
The introduction of an adjustment device with a contact section that can be supported on the movement rail, allowing for stepless vertical and inclination adjustments, which can be operated from either side and integrated into the existing transverse wall sections without significant additional space or material changes, using mechanisms like eccentric, threaded, or sliding arrangements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If an adjustment device is provided for vertical adjustment of the first furniture part, then the mounting precision is improved, but the device complexity increases
Solution Approach 1:
The contact section acts as an intermediary element between the adjustment device and the movement rail. It transfers the adjustment movement from the adjustment device to the first furniture part, enabling precise vertical and inclination adjustments without requiring the adjustment device to directly interact with both the furniture part and the rail, thus simplifying the overall device complexity while maintaining mounting precision.
Solution Approach 2:
The adjustment device is segmented into distinct functional components: an adjustment mechanism portion and a contact section. This segmentation allows the adjustment device to be integrated into the transverse wall section while maintaining independent adjustment functionality, resolving the contradiction between precision and complexity by separating the adjustment function from the structural function.
2Ease of operation
If the adjustment device is integrated into the transverse wall section, then the ease of operation is improved, but the ease of manufacture worsens
Solution Approach 1:
The adjustment device incorporates dynamic adjustment mechanisms (such as threaded arrangements, sliding arrangements, or eccentric arrangements) that allow the first furniture part to be easily adjusted vertically and in inclination after mounting. These dynamic elements are integrated into the transverse wall section, providing ease of operation while the modular design allows for relatively straightforward manufacturing and assembly.
Solution Approach 2:
The adjustment device is nested within the transverse wall section, with the contact section extending to interact with the movement rail. This nesting approach integrates the adjustment functionality into the existing structural element without requiring separate external components, improving ease of operation while maintaining manufacturability through efficient use of space.
3Measurement precision
If a contact section is provided on the adjustment device to contact the movement rail, then the measurement precision is improved, but the device complexity increases
Solution Approach 1:
The contact section serves as a precise intermediary contact point between the adjustment device and the movement rail. It provides a well-defined geometric interface that enables accurate measurement and control of the inclination adjustment, achieving high measurement precision while adding minimal complexity through its simple contact geometry.
Solution Approach 2:
The contact section replaces complex mechanical coupling mechanisms with a simple contact interface. Instead of using elaborate mechanical linkages to achieve precise inclination adjustment, the patent uses a direct contact section that interacts with the movement rail, substituting complex mechanics with a simpler contact-based system that achieves equivalent or superior precision.

AI summary
The furniture has a drawer (27) movably guided opposite to a furniture part i.e. furniture body, over a guide unit (24) i.e. sub lift. The guide unit includes a body rail (26) and a movement rail (25) arranged at the respective drawer and the furniture part. An adjusting device (11) adjusts the drawer in a vertical direction relative to the movement rail in a mounted condition. A contact section is provided at the adjusting device and supported at the movement rail so that an inclined adjustment of the drawer is carried out by an adjusting movement of the contact section.
