Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for coupling drawers with extendable rails of pull-out guides face challenges in lateral adjustment due to component tilting and difficulty in accessing adjustment options, leading to inaccuracies in drawer alignment and assembly.
Innovation Solution
A device with a fastening part and a coupling part that can be adjusted linearly relative to each other using an adjusting wheel, which converts rotary movement into linear movement through axially spaced devices, ensuring even force transmission and preventing tilting, along with a self-locking mechanism for maintaining adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the adjusting wheel is used to move the fastening part and coupling part linearly relative to each other, then lateral adjustment precision is improved, but component tilting occurs making further adjustment more difficult
Solution Approach 1:
The device is divided into a fastening part and a coupling part that can move independently relative to each other. The adjusting wheel is integrated into one of these parts, allowing linear movement without tilting the entire assembly. This segmentation enables precise lateral adjustment while maintaining component stability.
2Volume of moving object
If the device is made compact to be mounted on the underside of the drawer base, then space utilization is improved, but adjustment options become difficult to access
Solution Approach 1:
The adjusting wheel is integrated into the coupling part, which itself is part of the compact assembly mounted on the drawer base. The adjusting mechanism is nested within the existing structure rather than adding external bulk, maintaining compactness while providing accessible adjustment through the integrated wheel.
3Manufacturing precision
If the fastening part and coupling part are moved linearly relative to each other, then lateral alignment accuracy is improved, but the device complexity increases
Solution Approach 1:
The adjusting wheel acts as an intermediary mechanism between the fastening part and coupling part. By using the wheel to convert rotational movement into linear displacement, the design achieves precise lateral alignment without requiring complex adjustment mechanisms or multiple components.
