Drawer Front Fixing Spacer for Mis-Trigger-Free Catching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fixing devices for attaching a front panel to a drawer often experience erroneous triggering of the catch device due to the pin of the furniture fitting not being correctly positioned, leading to improper assembly or disassembly.
Innovation Solution
Incorporating deflection elements, such as laterally projecting projections or knobs, on the guide plate to prevent the furniture fitting's leg from triggering the spring-loaded catch element, ensuring accurate alignment and secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the catch device is designed to be easily triggered for quick assembly, then the assembly speed is improved, but erroneous triggering occurs when the pin is not yet correctly positioned
Solution Approach 1:
The guide plate with deflection elements performs a preliminary action by guiding the furniture fitting into the correct position before the pin can trigger the catch element. The deflection elements prevent the pin from triggering the catch element until the fitting is properly aligned, ensuring correct positioning precedes the triggering action.
Solution Approach 2:
The guide plate acts as an intermediary component between the furniture fitting and the catch device. It mediates the interaction by using deflection elements to control when and how the pin can engage the catch element, preventing erroneous triggering while maintaining smooth assembly operation.
2Reliability
If the guide plate is made wider to accommodate multiple deflection elements, then the prevention of erroneous triggering is improved, but the device complexity increases
Solution Approach 1:
The guide plate is segmented into multiple functional zones with individual deflection elements positioned at specific locations. Each deflection element serves a specific purpose in guiding different parts of the furniture fitting, allowing the wide guide plate to manage complex guidance tasks through modular segmentation rather than a single complex structure.
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
Prevents erroneous triggering and ensures correct assembly by ensuring the furniture fitting's leg cannot accidentally engage the catch element, providing a secure and reliable fixing mechanism with adjustable features for precise alignment and release.
Implementation Method 1
a movable spring-loaded catch element which can be triggered by the pin and holds the pin

AI summary
A fixing device for fixing a front panel on a drawer includes a furniture fitting which is preassembled on the front panel. The furniture fitting has at least one connecting piece which projects from the front panel and a pin which runs transverse to the connecting piece. A catching device is associated with the drawer. The catching device automatically retains the furniture fitting when the furniture fitting is inserted, and the catching device has a movable spring-loaded catching element which is triggered by the pin and which retains the pin. The catching element is moved along a guiding plate. A deflecting element is provided on a guiding plate face near the front panel for deflecting the furniture fitting which is preassembled in the front panel. The deflecting element is formed as a projection which projects laterally.
