Drawer Front Fitting for Pivoted Top-Element Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drawer assembly methods require significant space for attaching top elements, especially when multiple drawers are stacked, leading to complexity and interference issues during assembly.
Innovation Solution
The attachment element is introduced into a recess of the fitting body and pivoted about a vertical axis, allowing lateral movement without increasing vertical space, enabling modular attachment and easy disassembly independent of drawer side walls or railing struts, using a two-part fitting body with a snap connection for secure installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If plate-shaped attachments are used to increase drawer height, then the effective capacity of the drawer is increased, but a large amount of space is required for introducing the attachments
Solution Approach 1:
The attachment element is inserted into a recess of the fitting body, nesting one component inside another. This allows the attachment element to be introduced without requiring additional external space, as it fits within the existing structural envelope of the drawer assembly.
Solution Approach 2:
The attachment element is pivoted about a vertical axis during installation, transitioning from a horizontal insertion path to a vertical pivoting motion. This dimensional change in the installation trajectory eliminates the need for increased vertical clearance space during assembly.
2Ease of operation
If tool-free attachment methods are used, then ease of assembly is improved, but reliable fixation of the attachment element may be compromised
Solution Approach 1:
The manual tool-based fastening system is replaced with an elastic retention mechanism where the elastic element automatically engages with the recess through elastic deformation and recovery. This self-actuating mechanical system provides reliable fixation without requiring external tools.
Solution Approach 2:
The elastic element automatically secures the attachment element to the fitting body through its own elastic properties. The system is self-securing, where the deformation and recovery of the elastic element itself provides the fixation force, eliminating the need for separate fastening operations.
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 method simplifies the assembly of top elements on drawers by reducing space requirements, allowing for tool-free installation and disassembly, and enabling independent mounting of top elements without disassembling the drawer, facilitating easier stacking and assembly of multiple drawers.
Implementation Method 1
an elastic element can be arranged in the recess, which is deformed during insertion of the attachment element into the recess and which restores its force after the attachment element has been inserted
