Arrangement for connecting a drawer side wall to another drawer wall
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drawer connection arrangements have complex designs and large overall heights, making it difficult to achieve thin, space-saving drawer side walls that meet the demand for elegant and space-efficient furniture designs.
Innovation Solution
A connecting device using a flat sheet metal bolt movably guided within the non-metallic drawer side wall, allowing for thin drawer side walls and a hidden, aesthetically pleasing design, with the bolt being linearly displaceable and accessible for detachable holding device release.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If conventional connecting devices are used in drawer side walls, then the connection function is achieved, but the drawer side wall thickness must be large to accommodate the connecting device
Solution Approach 1:
The invention extracts the connecting device from the traditional complex multi-component design and reduces it to a single flat sheet metal bolt. This extracted simplified connecting device can be linearly displaced within the drawer side wall to achieve connection, eliminating the need for thick drawer side walls while maintaining the connection function.
Solution Approach 2:
The connecting device is designed as a flat sheet metal bolt with thickness between 1-5mm, which is a thin film structure. This thin film connecting device can be linearly displaced within the drawer side wall and still provide adequate connection strength, enabling thin drawer side wall designs.
2Shape
If the connecting device is placed inside the drawer side wall for aesthetic reasons, then the appearance is improved, but the detachability function may be compromised
Solution Approach 1:
The invention introduces an intermediary actuating area on the underside of the flat sheet metal bolt that is accessible from outside the drawer side wall. This actuating area serves as a mediator that allows users to operate the connecting device for detachment without exposing the connecting device itself, thus maintaining both aesthetics and functionality.
3Device complexity
If a single flat sheet metal bolt is used for connection, then the design is simplified and cost-effective, but the ability to compensate for assembly tolerances is reduced
Solution Approach 1:
The invention makes the flat sheet metal bolt dynamically displaceable within the drawer side wall along a linear path. This dynamic capability allows the single connecting device to adapt to assembly tolerances and variations in drawer side wall dimensions, particularly in wooden drawers that may expand or contract with humidity changes, thereby maintaining connection reliability despite the simplified design.
