Securing device for securing a panel of a drawer to a frame
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fastening devices for drawer panels are either complex, require a stable metallic side frame, or involve multiple components, making them difficult to install and remove within narrow hollow chamber frames.
Innovation Solution
A fastening device with a panel support and adapter featuring spring-loaded wedge slides that can be easily locked and unlocked using a single unlocking device, allowing for secure positioning and simple installation within narrow frames.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a multi-part panel support with wedges is used to secure the panel, then the panel can be firmly fixed to the frame, but the device structure becomes complex and requires a stable metallic side frame with large wall thickness
Solution Approach 1:
The fastening device is divided into separate functional components: an adapter with catching devices that attaches to the frame, and a panel support with connecting elements that attaches to the panel. This segmentation allows each component to be optimized independently and simplifies the overall structure compared to a monolithic multi-part wedge system.
Solution Approach 2:
The connecting elements of the panel support are received within the catching devices of the adapter, creating a nested arrangement where the panel support fits into the adapter structure. This nesting eliminates the need for separate wedge components and reduces structural complexity while maintaining secure fixation.
2Ease of operation
If a rotatable catch hook system with transmission guide rod is used, then the panel can be secured and released, but the device structure becomes complex and difficult to install within narrow hollow chamber frames
Solution Approach 1:
The complex transmission guide rod mechanism is completely removed from the design. Instead, the catching devices use a simple spring-loaded wedge slide mechanism that can be actuated directly, extracting the unnecessary intermediate transmission components while preserving the attachment and detachment functionality.
Solution Approach 2:
The catching devices utilize spring-loaded wedge slides that can change their engagement state through simple linear displacement rather than rotational movement. This parameter change from rotational to linear actuation simplifies the mechanism and enables installation in narrow hollow chamber frames where rotational space is limited.
3Ease of operation
If spring-loaded wedge slides are used in catching devices, then the panel support can be securely positioned and easily removed, but the frame must accommodate the additional components
Solution Approach 1:
The spring-loaded wedge slides are integrated directly into the catching devices of the adapter, which is itself attached to the frame. This merging of functions eliminates the need for separate additional components and minimizes the space required in the frame structure.
Solution Approach 2:
The adapter serves multiple functions: it attaches to the frame, houses the catching devices with wedge slides, and provides the structural interface for panel support attachment. This multi-functionality reduces the need for additional dedicated components and minimizes overall space requirements.
