Rotary-to-Linear Drawer Stop Adjuster for Uniform Front Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for adjusting the depth position of drawers on furniture lack simplicity and intuitive operation, leading to uneven alignment of drawer fronts when vertically offset rail guides are used, resulting in an unattractive and non-continuously level front image.
Innovation Solution
A device with a rotatably mounted adjusting element that allows for linear adjustment of the stop position, enabling intuitive depth adjustment of drawers by converting rotary movement into linear displacement, which can be fixed in various positions to limit the drawer's sliding movement, ensuring uniform alignment of drawer fronts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If existing adjusting devices are used for drawer depth adjustment, then the drawer depth can be adjusted, but the operation is not intuitive and the design is complex
Solution Approach 1:
The adjusting element is designed as a wheel with a curved rotating perimeter that engages with a helical engagement profile on the sliding element. This curved mechanical interface converts simple rotational motion into linear displacement of the stop, providing intuitive operation without complex mechanisms. The user simply rotates the wheel to adjust the stop position along the drawer rail.
2Adaptability or versatility
If vertically offset rail guides are used for multiple drawers, then space is optimized, but the drawer fronts become unevenly aligned
Solution Approach 1:
The adjusting device with the rotatable wheel and sliding stop is designed as a universal adjustment mechanism that can be applied to any drawer with a rail guide, regardless of the rail's vertical position. Each drawer can independently adjust its stop position to compensate for vertical offsets in the rail guides, ensuring that all drawer fronts align uniformly with the furniture facade even when the rail guides are at different heights.
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
The device allows for easy and intuitive adjustment of drawer depth, ensuring a uniformly flush front image on furniture by allowing the stop to be set in different positions, addressing the issue of uneven drawer fronts when rail guides are vertically offset.
Implementation Method 1
The adjusting element and a sliding element of the device coupled to the adjusting element are designed in such a way that the sliding element can be linearly adjusted by a rotary movement of the adjusting element
