Drawer Support Web and Drive Holder Assembly for Flush Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drive mechanisms for furniture drawers require significant space and complex installation, especially when mounted on the drawer bottom, which limits design flexibility and efficiency.
Innovation Solution
A compact fastening method using a support rib and holding device with integrated fastening elements that form a flush drawer bottom surface, allowing for a narrower mounting area and secure attachment without additional components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the drive mechanism is mounted on the drawer bottom, then the space requirement is reduced, but the mounting area becomes wider and more complex
Solution Approach 1:
The patent merges the support rib (which provides structural support) with the mounting function for the drive mechanism. The support rib integrates the bearing area for the drawer bottom and the receptacle for the fastening element into a single component, eliminating the need for separate mounting brackets and reducing the overall mounting area width.
Solution Approach 2:
The patent transitions from a two-dimensional mounting approach (mounting plate on drawer bottom) to a three-dimensional approach using the support rib's vertical structure. The receptacle extends in the direction away from the drawer bottom, allowing the fastening element to engage vertically rather than requiring a wide horizontal mounting area.
2Volume of moving object
If the drive mechanism is mounted on the drawer bottom, then the space requirement is reduced, but the installation becomes more complex
Solution Approach 1:
The support rib combines multiple functions into one component: it provides structural support for the drawer bottom, contains the receptacle for fastening, and eliminates the need for separate mounting brackets. This integration simplifies the installation process by reducing the number of parts that need to be assembled.
Solution Approach 2:
The support rib is designed to be part of the drawer side panel assembly, meaning the structural support element and the mounting element are self-integrated. The receptacle is formed as part of the support rib structure, eliminating the need for separate mounting operations and reducing installation complexity.
3Ease of manufacture
If a separate mounting bracket is used, then the mounting is simplified, but the space requirement increases
Solution Approach 1:
The patent eliminates the separate mounting bracket by merging its function into the support rib. The receptacle formed as part of the support rib performs the mounting function, while the support rib itself provides the structural support, reducing the overall space requirement.
Solution Approach 2:
The support rib serves multiple functions: it provides structural support for the drawer bottom, acts as the mounting structure for the drive mechanism, and eliminates the need for separate mounting brackets. This multi-functionality reduces the overall component count and space requirement.
