Pull-Out Rotating Bag Frame for Easier Waste Bag Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing waste receptacles require inconvenient and time-consuming processes to remove full trash or waste bags, involving lifting off covers or opening the entire top, which leads to strain and inefficiency.
Innovation Solution
A waste receptacle design featuring a stationary outer housing with a moveable trash or waste bag support frame that can be slid outward and rotated, allowing for easy access and removal of full bags without lifting, utilizing a foot actuator to open a cover and a damping mechanism for smooth operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the entire top of the container is opened to remove full bags, then access to the bag is provided, but the operation becomes time-consuming and requires lifting the full bag
Solution Approach 1:
The container is divided into a stationary outer housing and a moveable inner bag support frame. The bag support frame can be independently extended outward from the housing, allowing the bag to be accessed and removed without opening the entire container top, thus saving time and effort.
Solution Approach 2:
The bag support frame is extracted as a separate moveable component from the stationary housing. This allows the support frame with the bag to be pulled outward for easy access and removal, eliminating the need to lift the full bag over the container top.
2Ease of operation
If the bag support frame is made moveable for easy access, then bag removal is simplified, but the device complexity increases
Solution Approach 1:
Only the bag support frame is made moveable while the outer housing remains stationary. This localized movability provides the necessary functionality for easy bag removal without requiring the entire container to be complex or movable, thus minimizing device complexity.
Solution Approach 2:
The container structure is designed with asymmetric functionality: the stationary outer housing provides structural simplicity, while the moveable inner bag support frame provides operational ease. This asymmetric design balances complexity and functionality.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables efficient and ergonomic removal and replacement of trash bags without the need for lifting, reducing strain and improving usability with a compact and reliable design.
Implementation Method 1
The cover hinge utilizes a pivot support that will provide damping as the cover is opened or closed.

AI summary
A waste receptacle has an outer cabinet housing and a waste or trash bag support frame that can be moved from a position where it is at least partially within the cabinet, to a position where the support frame is extended sufficiently so it can be rotated about an upright axis to provide access to a bag held on the support frame. The support frame has an open ring on which a waste bag can be placed. The ring is spaced upwardly from the bottom of the bag support frame so that when the waste bag is full, it can be detached from the ring and dropped down for removal, rather than being lifted up through a container opening or support. The waste receptacle can have a cover that can be actuated to move from a closed position overlying the bag support frame to an open position.
