Pull-Out Waste Bin Frame for Standard Drawer Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing furniture fittings for pull-out waste collection devices are not adaptable to standard drawers, requiring specific modifications and being expensive due to complex constructions and variability in drawer depths, which complicates installation and reduces rigidity.
Innovation Solution
A furniture fitting with a receiving frame and stabilizing frame that supports the mounting frame on the front wall and rear cross brace of a standard drawer, allowing for a free distance above the frames, enabling compatibility with various drawer designs without additional support on the frames or rear wall, thus simplifying installation and maintaining rigidity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the mounting frame is supported on the frames and rear wall of a conventional drawer, then the structure provides adequate support, but the fitting cannot be adapted to standard drawers and requires specific modifications
Solution Approach 1:
The furniture fitting is divided into separate functional components: a stabilizing frame that attaches to the drawer bottom and sides, and a mounting frame that supports the waste container. This segmentation allows each component to be independently designed and adapted to standard drawer configurations without requiring complex integrated modifications.
Solution Approach 2:
The stabilizing frame is designed with universal attachment features that can be adapted to various standard drawer configurations. The support devices are positioned to work with common drawer structures, making the fitting compatible across different manufacturers and models without requiring custom modifications.
2Device complexity
If the mounting frame is supported exclusively on the front wall and rear cross brace, then the construction is simplified and rigidity is maintained, but additional support on frames is eliminated
Solution Approach 1:
The stabilizing frame is installed first to provide preliminary structural support and positioning. This preliminary action creates a stable base that allows the mounting frame to be securely attached to the front wall and rear cross brace without requiring additional support on the side frames, maintaining rigidity through proper installation sequence.
3Volume of moving object
If the receiving frame is positioned close to the frames, then space is optimized, but collisions may occur during drawer extension
Solution Approach 1:
The stabilizing frame acts as an intermediary structure between the drawer frames and the mounting frame. It provides a stable attachment base that positions the mounting frame at an optimal distance, preventing collisions during drawer extension while maintaining efficient space utilization through controlled positioning.

AI summary
A furniture fitting (1) for forming a pull-out waste collection device comprises a mounting frame (2) which has at least one opening (3) for hanging in a waste collection container (4, 5), supporting devices for supporting the mounting frame (2) on a drawer (41), has lateral frames (14) encompassing the base edge receptacles (15) with a maximum height above the base edge receptacles (15) and a front wall connecting the frames (14) at the front, and a stabilizing frame (10) for the drawer (41 ), which has two longitudinal struts (18) and a front cross strut (17) and a rear cross strut (9). The support devices are designed to exclusively support the mounting frame (2) on the front wall and on the rear cross member (9), with the mounting frame (2) running at a distance above the stabilizing frame (10), the distance being greater than the maximum height of the frames (14).
