Drawer Frame Front Panel Clamping Lock to Prevent Tilting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drawer frames with spring-loaded catching parts for front panels experience undesirable tilting movements during use, especially with heavily loaded drawers, leading to delayed drawer movement and insufficient movement behavior.
Innovation Solution
A clamping locking device is introduced, featuring a movable wedge element and guide track, which automatically locks the catching part in a stable position, preventing relative movement and allowing for adjustable positioning of the front panel without manual actuation, using a spring to maintain the wedge element in a wedged position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a spring-loaded catching part is used to attach the front panel to the drawer frame, then the front panel can be detachably and automatically latched, but unwanted tilting movements occur during drawer actuation
Solution Approach 1:
The wedge element is pre-positioned in the locking device to automatically engage with the catching part when the front panel is inserted. This preliminary positioning ensures that as soon as the spring-loaded catching part latches the front panel, the wedge element simultaneously prevents tilting movements by engaging with the catching part, eliminating the need for separate locking actions.
Solution Approach 2:
The wedge element acts as an intermediary component between the catching part and the drawer frame. It mediates the connection by converting the spring force into a clamping action that secures the catching part in a fixed position, thereby preventing unwanted tilting movements while maintaining the automatic latching function.
2Stability of the object's composition
If the front panel is securely locked to prevent tilting movements, then stability is improved, but adjustment options for the front panel position are reduced
Solution Approach 1:
The locking device incorporates a movable wedge element that can dynamically switch between locked and unlocked states. When adjustment is needed, the wedge element can be disengaged from the catching part, allowing the front panel to be repositioned. Once positioned, the wedge element automatically re-engages to lock the panel in place, providing both stability and adjustability.
Solution Approach 2:
The locking device is designed to automatically lock the catching part in the correct position without requiring manual intervention. The spring-loaded mechanism and wedge element work together to self-secure the front panel once it is inserted, eliminating the need for separate locking actions while maintaining adjustment capability during the insertion process.
3Stability of the object's composition
If a locking device is added to prevent tilting movements, then stability is improved, but device complexity increases
Solution Approach 1:
The locking function is merged with the existing spring-loaded catching part mechanism. The wedge element is integrated into the fastening device structure and works in conjunction with the catching part, rather than being a separate, independent locking mechanism. This merging approach prevents tilting movements while minimizing the increase in device complexity.
Solution Approach 2:
The wedge element serves as a simple intermediary component that bridges the catching part and the drawer frame. Its geometry is designed to automatically engage with the catching part and prevent tilting movements through its wedge shape, which converts spring force into a clamping action. This simple intermediary element provides the needed stability without significantly complicating the overall device 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
The solution ensures a secure, rigid attachment of the front panel to the drawer frame, minimizing unwanted tilting and allowing for targeted adjustment of the front panel's position, enhancing the movement behavior and stability of the drawer.
Implementation Method 1
an arrangement of a spring (either by the spring of the catching part or optionally also by a separate spring) is favorable, which automatically presses the wedge element in the direction of the wedge position
