Personal Trash Bag Holder with Stripping Membrane
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing trash bag holders are cumbersome and fail to provide both self-supported and carried modes of utilization, and they do not protect the trash bag when using refuse picking tools, making it difficult and hazardous to collect trash over large areas.
Innovation Solution
A personal trash bag holding apparatus with a base assembly, insert assembly, and opening ring assembly that allows for quick and easy collection of trash, featuring a wearable strap and waist belt for hands-free operation, a stripping membrane for safe insertion of refuse, and secure fastening mechanisms to maintain the trash bag open.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a trash can with a liner is carried, then trash collection is possible, but the combination becomes heavy and bulky
Solution Approach 1:
The patent extracts the essential function of holding a trash bag from the traditional trash can, keeping only the lightweight plastic bag while using a separate holder to support it. This separates the containment function (bag) from the support function (holder), eliminating the need for a heavy can while maintaining trash collection capability
Solution Approach 2:
The device is divided into separate functional components: a holder for support, a plastic bag for containment, and optional protective components. This segmentation allows each component to be optimized independently, resulting in a lighter overall system compared to a monolithic trash can
2Weight of moving object
If just the liner is carried, then weight is reduced, but it becomes difficult to keep the bag open when placing refuse inside
Solution Approach 1:
The holder acts as an intermediary device between the user and the trash bag, providing structural support to keep the bag open and upright. This mediator enables the lightweight bag to function effectively without requiring the user to manually maintain its shape, solving the problem of keeping the bag open while carrying only the lightweight liner
3Ease of operation
If long tongs or a sharp stick are used as collection aid, then refuse can be picked up, but the user must touch the refuse when removing it from the collection aid, exposing the worker to extra hazards
Solution Approach 1:
The stripping membrane is designed to automatically strip refuse from the collection aid as it passes through the opening. The membrane's flexible, self-cleaning surface causes refuse to detach and fall into the bag without requiring the user to manually remove it, thereby eliminating direct contact with hazardous materials
Solution Approach 2:
The stripping membrane serves as an intermediary between the collection aid and the trash bag, facilitating the transfer of refuse while preventing direct contact between the user and the refuse. The membrane captures and transports refuse automatically, reducing exposure to hazards
4Ease of operation
If conventional trash bag holders are used, then the bag can be held open, but they do not provide protection for the trash bag when being filled with a refuse picking tool
Solution Approach 1:
The holder includes a protective component positioned to cushion or protect the opening of the trash bag before refuse picking tools can damage it. This preventive measure is built into the holder structure, providing beforehand protection against punctures or tears during the trash collection process

AI summary
An apparatus for holding trash bags and facilitating trash pick up includes a bag holding base ring and interchangeable insert ring and opening ring which selectably attach to the base ring. The trash bag is secured between the opposing pairs of rings, which are each attachable to a waist belt worn by the user or can be carried individually by an attachable handle. The insert ring also includes a stripping membrane along a top surface to remove the refuse from a trash picker and retain it inside the bag.
