Rear Wall Attachment Device for Tool-Free Drawer Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drawer assembly kits require precise matching of components, making it difficult to achieve a flexible combination of drawer frames and rear panels, and often necessitate tool use for assembly.
Innovation Solution
A device for attaching a rear wall to a movable furniture part, featuring engagement means that allow for tool-free assembly, with pre-assembly capabilities and adjustable holding mechanisms to secure the rear wall in place, utilizing a cuboid base body with spring means for noise reduction and a latching connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional drawer assembly kits are used to connect rear wall to drawer frame, then the connection is secure and stable, but the assembly process requires tools and precise component matching, reducing ease of assembly and flexibility
Solution Approach 1:
The connection system is divided into separate functional components: the device with engagement means attaches to the rear wall, while the rear wall holder with opening remains on the drawer frame. This segmentation allows independent assembly of each component and eliminates the need for precise pre-matching between frame and rear wall components.
Solution Approach 2:
The device acts as an intermediary element between the rear wall and the drawer frame. It features engagement means that connect to the rear wall holder's opening, providing a standardized interface that simplifies assembly and enables flexibility in component combinations without requiring tool use.
2Reliability
If traditional drawer assembly kits are used, then structural stability is achieved, but tool-free assembly and on-site pre-assembly capabilities are lost
Solution Approach 1:
The device can be pre-assembled to the rear wall at the factory or on-site before final installation. The engagement means are pre-positioned on the rear wall, allowing the rear wall to be prepared in advance and then simply connected to the drawer frame later without requiring tools during final assembly.
Solution Approach 2:
The engagement means and rear wall holder are designed to self-align and self-connect without requiring external tools or complex alignment procedures. The opening in the rear wall holder receives the engagement means through a simple insertion motion, providing tool-free assembly while maintaining reliable connection stability.
