Inset Drawer Stop Adjustment With Resilient Wedge Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Furniture with inset drawers faces challenges in defining the end point of the closing movement due to manufacturing tolerances and assembly deviations, leading to inconsistent front images and lack of a suitable stop point on the front side or body.
Innovation Solution
A device with a resiliently deflectable stop part and a wedge gear arrangement allows for precise adjustment of the stop position, enabling easy and precise setting of the stop position during closure, even in space-constrained areas, using a compact and reliable mechanism that can be connected to either the furniture part or the body.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If an adjustable stop is provided to define the end point of the closing movement, then the stop position can be determined, but the device becomes more complex and requires additional components
Solution Approach 1:
The patent combines the stop part and the adjustment unit into a single integrated component. The stop part is formed as one piece with the adjustment unit, eliminating the need for separate stop components and reducing overall device complexity while maintaining precise stop position determination capability
Solution Approach 2:
The stop part is designed to be resiliently deflectable, allowing it to dynamically adapt during the closing movement. The stop part can be pressed against the furniture part during closure and then resiliently returns to its original position, providing automatic adjustment without complex mechanical mechanisms
2Ease of operation
If the stop part is made resiliently deflectable to enable easy adjustment, then the adjustment ease is improved, but the reliability of the stop position may be compromised
Solution Approach 1:
The adjustment unit is pre-configured with a wedge gear arrangement that automatically locks the stop part in its adjusted position. When the stop part is deflected during adjustment, the wedge gear mechanism engages to prevent backward movement, ensuring the adjusted position is maintained reliably without requiring additional locking components
Solution Approach 2:
The wedge gear arrangement acts as an intermediary between the resilient stop part and the adjustment unit body. It translates the linear deflection movement of the stop part into a rotational movement of the adjustment element, providing both ease of adjustment and reliable position maintenance through its self-locking geometric mechanism
3Device complexity
If a wedge gear arrangement is used to convert rotational movement to adjustment movement, then the device becomes more compact and reliable, but the manufacturing complexity increases
Solution Approach 1:
The wedge gear arrangement is integrated directly into the one-piece adjustment unit structure. The wedge gear features are formed as integral parts of the molded plastic component, eliminating the need for separate gear components and simplifying manufacturing through single-shot molding or similar processes
Solution Approach 2:
The wedge gear arrangement utilizes the elastic deformation characteristics of the resilient stop part to enable adjustment. By changing the material parameters of the stop part to be resilient, the system achieves compactness and reliability without requiring complex mechanical gear assemblies
