Assembly formed by a drawer side wall and a connection device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drawer connection systems, such as those described in WO 2013/149272 A1, face challenges in assembly and adjustment due to limited positional flexibility of the front panel relative to the drawer side wall, leading to potential tilting and adverse effects on furniture joint patterns, especially with manufacturing and assembly tolerances.
Innovation Solution
Incorporating a height adjustment device in the drawer side wall, which allows for transverse adjustment of the mounting device relative to the retaining bar, featuring a curved or circular retaining bar and guide with corresponding contours, a spring element for reliable latch release, and a locking mechanism with a pivoting lever and actuation shaft for precise positioning and easy adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the front panel is connected directly to the drawer side panel using a fixed retaining bar, then the assembly structure is simple, but the front panel cannot be adjusted in position, leading to misalignment due to manufacturing and assembly tolerances
Solution Approach 1:
The retaining bar is designed to be movable along the drawer side panel rather than fixed, allowing dynamic adjustment of the front panel position. The retaining bar can be positioned at different locations on the drawer side panel and locked in place, enabling adaptation to manufacturing tolerances and misalignment issues while maintaining a relatively simple overall structure.
2Manufacturing precision
If the retaining bar is made movable to allow position adjustment, then the front panel alignment is improved, but the assembly process becomes more complex and time-consuming
Solution Approach 1:
The retaining bar is pre-equipped with multiple positioning locations or adjustment mechanisms that allow for quick selection and locking. The drawer side panel includes pre-formed guides or slots that facilitate the rapid positioning and securing of the retaining bar, reducing the time required for alignment adjustments during assembly.
3Ease of operation
If the retaining bolt is directly mounted in the drawer side panel, then the structure is compact, but the retaining bolt cannot be reliably released, leading to assembly difficulties
Solution Approach 1:
A release mechanism or intermediary component is introduced between the retaining bolt and the drawer side panel. This intermediary allows the retaining bolt to be reliably held in the locked position during assembly while providing a simple release action (such as pressing a button or moving a lever) to disengage the bolt when needed, improving ease of operation without significantly increasing overall structural complexity.
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
This solution enhances the ease of assembly and adjustment by allowing for precise positioning of the front panel relative to the drawer side wall, reducing the risk of tilting and improving the joint pattern consistency across furniture pieces, while maintaining a compact structure without increasing the drawer side wall thickness.
Implementation Method 1
a spring element, in particular a torsion spring, with which the at least one retaining bolt can be acted upon with a force in the direction of the release position
