Drawer Rear Wall Assembly Using Adapter-Fixed Latching Connector
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drawer designs face challenges in achieving stable and easy assembly of a rear wall to a side frame, with limitations in stability and ease of assembly due to tolerances in existing connection methods.
Innovation Solution
A drawer design featuring a connecting element with latching means on the side frame, which is fixed via an adapter, and a securing element that can be clamped to provide non-positive fixation, allowing for repeated assembly and accommodating different types of rear walls through optional screw fastening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a connector with receptacle is used to fix wall elements, then assembly is simplified, but connection stability is limited by tolerances
Solution Approach 1:
The connection system is divided into multiple functional components: a connector fixed to the side frame, a connecting element with latching means that engages with the rear wall, and a securing element that locks the connecting element in place. This segmentation allows each component to perform its specific function optimally while maintaining overall connection stability.
Solution Approach 2:
The connector is pre-fixed to the side frame before the rear wall is installed. The connecting element is designed with latching means that can engage with the rear wall in a predetermined manner. This preliminary preparation ensures that when assembly occurs, the components are already positioned to achieve stable connection, reducing the impact of tolerances.
2Ease of operation
If a corner connector with two parts is used to fix rear wall to side frame, then assembly is enabled, but device complexity increases
Solution Approach 1:
The connector, connecting element, and securing element are designed to work together as an integrated system. The securing element combines the functions of locking and fixation, while the connecting element integrates the latching mechanism with the engagement features. This merging reduces the number of separate components needed compared to traditional two-part corner connectors.
3Adaptability or versatility
If the same connecting element is used for different rear walls, then versatility is improved, but manufacturing precision requirements increase
Solution Approach 1:
The connecting element is designed with universal latching means that can engage with different types of rear walls (metal sheet, wooden panel, plastic) through standardized engagement features. The latching mechanism incorporates tolerance compensation features that allow the same connecting element to accommodate variations in rear wall dimensions and positions while maintaining secure connection.
