Refuse Receptacle Bag Support with Slit Flaps for Vacuum Elimination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing refuse receptacle accessories do not effectively address the vacuum created when removing disposable bags, nor can they be easily retrofitted into different shaped and sized receptacles, leading to difficulties in bag removal and maintaining cleanliness and odor control.
Innovation Solution
A refuse receptacle accessory featuring a bag support with folds or slits and flaps that enhance airflow, allowing secure fitting into various receptacle shapes and sizes, and a cover assembly to absorb spills and reduce odors, facilitating easy bag removal and improving sanitation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a bag support is designed to fit securely in a refuse receptacle, then the bag support adheres well to the receptacle walls, but a vacuum seal is created that makes bag removal difficult
Solution Approach 1:
The bag support is divided into multiple flaps (first flap, second flap, third flap, fourth flap) that can move independently. This segmentation allows the flaps to separate and break the vacuum seal during bag removal, while still providing secure adherence when the flaps are in their closed position against the receptacle walls.
Solution Approach 2:
The flaps are designed to be movable rather than fixed, allowing them to dynamically adjust between a closed position for secure bag fitting and an open position for vacuum release during removal. The folds and flaps create a dynamic structure that responds to the forces applied during bag insertion and removal.
2Manufacturing precision
If a bag support is designed for a specific receptacle shape and size, then it fits that receptacle well, but it cannot be used in other shaped or sized receptacles
Solution Approach 1:
The bag support is designed with multiple flaps and folds that can adapt to different receptacle shapes and sizes. The flaps can be positioned and shaped to conform to various geometries, making a single bag support design compatible with multiple receptacle types rather than requiring custom designs for each receptacle.
Solution Approach 2:
The bag support structure allows for changes in the configuration and positioning of flaps and folds to accommodate different receptacle parameters (shape, size, curvature). This flexibility enables the same basic design to be adapted to various receptacle specifications without requiring complete redesign.
3Strength
If the bag support structure is made complex to achieve secure fitting and vacuum control, then bag adherence is improved, but the device becomes more complicated and expensive
Solution Approach 1:
The bag support utilizes flexible material with integrated folds and flaps that provide the necessary structural complexity for secure fitting and vacuum control without requiring multiple separate components. The flexibility of the material allows a relatively simple monolithic structure to achieve complex functional behavior through its geometric features.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution eliminates the vacuum seal during bag removal, making it easier to handle bags, reduces odors, and maintains cleanliness, while being adaptable to various receptacle shapes and sizes at an economical cost.
Implementation Method 1
the folds enhance airflow and prevent suction during removal and fitting of a bag within a refuse receptacle
Implementation Method 2
a cover assembly to absorb spills and reduce odors
Implementation Method 3
the flaps further allow fitting and adherence of the bag support within a variety shaped sizes and shaped refuse receptacles

AI summary
A refuse receptacle accessory including a bag support assembly, a cover assembly and a receptacle assembly. A bag support is placed inside of a receptacle. The bag support includes flaps and slits that extend outwardly and away from the bag support along a perimeter thereof. The flaps and slits allow for enhanced airflow to occur within the receptacle to eliminate the vacuum that is created between the receptacle and the bag within. Further, a cover is mounted to a top side of the bag support. The cover is absorbent and scented to increase cleanliness and sanitation within the receptacle. The eliminated vacuum facilitates the removal of the bag from the receptacle in a manner that is efficient and easy to accomplish.
