Drawer Front Panel Alignment Using Rotary Eccentric Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drawer adjustment devices are either complex and costly to manufacture, require a stable attachment frame, or are unsuitable for drawers with high front panels and low side frames, and lack user-friendly accessibility.
Innovation Solution
A drawer adjustment device with a holding part fixed to the front panel and a supporting part fixed to the side frame, featuring a rotary part for adjustment, allowing for flexible mounting and easy accessibility, using few components and no fastening means, with the rotary part designed as an eccentric or worm wheel for quick adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a frame attachment with adjustment means is provided to adjust the inclination of the front panel, then the front panel alignment is improved, but the device complexity and manufacturing cost increase due to numerous components and stable attachment requirements
Solution Approach 1:
The adjustment device is divided into two separate parts: a holding part that attaches to the front panel and a supporting part that attaches to the side frame. This segmentation allows each part to be simple in structure while working together to achieve the alignment function, reducing overall device complexity.
Solution Approach 2:
The holding part and supporting part act as intermediaries between the front panel and side frame, providing a simple connection mechanism that enables adjustment without requiring complex attachment frames or multiple adjustment components.
2Ease of manufacture
If a slide fixed to the side frame is used for front adjustment, then the structure is simplified, but the device becomes less suitable for drawers with high front panel and low side frame due to fixed attachment requirements
Solution Approach 1:
The holding part and supporting part design allows the adjustment device to be universally applied to different drawer types, including those with high front panels and low side frames. The parts can be attached at different positions and orientations to accommodate various drawer configurations.
Solution Approach 2:
The holding part and supporting part are designed to be linearly displaceable relative to one another, providing dynamic adjustment capability that adapts to different drawer geometries and panel heights, unlike fixed attachment solutions.
3Device complexity
If the rotary part is arranged directly on the front panel or side frame, then the adjustment mechanism is compact, but the accessibility for user operation is reduced
Solution Approach 1:
The rotary part is positioned at a distance from both the front panel and side frame, creating spatial separation that improves accessibility. The holding part and supporting part extend to bridge the gap between the rotary part and the attachment points, allowing easy user operation while maintaining a compact overall structure.
4Reliability
If multiple fastening means are used to secure the adjustment device, then the attachment stability is improved, but the assembly effort and manufacturing complexity increase
Solution Approach 1:
The holding part and supporting part are designed to work together as an integrated adjustment mechanism, reducing the number of separate fastening means required. The linear displacement capability allows the parts to self-align and secure with minimal fastening, reducing assembly effort while maintaining stability.
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 simple and cost-effective production and assembly of the adjustment device, allowing for easy alignment of front panels relative to side frames, even with significant height differences, and provides user-friendly and secure adjustment without the need for additional fastening means.
Implementation Method 1
The rotary part is preferably designed as an eccentric, which has an axis of rotation and an eccentric disc, so that an adjustment process can be carried out quickly and effectively.

AI summary
An adjusting device (10, 30) for aligning a front panel (4) on a drawer (1) comprises a holding part (11, 33) that can be fixed on the front panel (4) and a holding part (11, 33) that can be fixed on a side frame (3) of the drawer (1). Supporting part (13, 31), wherein the holding part (11, 33) and the supporting part (12, 31) are linearly displaceable relative to each other and a rotating part (13, 35) is provided to rotate the holding part (11, 33) on the supporting part (12, 31) to be adjusted and fixed in the desired position. This enables a stable adjustment even with high front panels (4).
