Dumpster Bag With Removable Rim And Integrated Loops
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dumpster bags lack efficient methods for lifting and dumping processes, particularly in handling large volumes, as they often require complex hoisting and securing mechanisms that can be cumbersome and prone to damage.
Innovation Solution
A method utilizing a flexible bag with multiple loops for lifting and dumping, where a hoist is engaged with upper loops for lifting and then released to lift using lower loops for dumping, allowing for remote control of the lifting process and using polyethylene/polypropylene fiber bags with removable rim and corner stays for increased flexibility and compact storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If traditional dumpster bags use PVC pipe rim stays and sewn-in corner stay panels to hold open form, then the bag maintains structural stability, but the bag becomes cumbersome and prone to damage during lifting and dumping operations
Solution Approach 1:
The patent removes the rigid PVC pipe rim stays and sewn-in corner stay panels from the bag structure. Instead, it uses a flexible rim made of woven material with integrated loops that can be easily engaged and disengaged from hoisting equipment, eliminating the cumbersome rigid stays while maintaining bag stability during use.
Solution Approach 2:
The patent employs a flexible rim constructed from woven material that can adapt its shape during lifting and dumping operations. This flexible structure replaces rigid stays, allowing the bag to be easily maneuvered while maintaining structural integrity when needed.
2Adaptability or versatility
If dumpster bags use multiple loops for lifting and dumping operations, then the bag provides versatile hoisting options, but the bag requires complex securing mechanisms that increase device complexity
Solution Approach 1:
The patent integrates multiple loops (four corner loops and two mid-side loops) into a single flexible rim structure. These loops serve multiple functions: corner loops for lifting, mid-side loops for dumping and securing, all within one unified rim design that reduces overall system complexity while maintaining operational versatility.
Solution Approach 2:
The patent combines multiple stay functions into a single flexible rim structure with integrated loops. Instead of separate rim stays and corner panels, the flexible rim unifies these elements, providing both structural support and multiple attachment points in one component.
3Strength
If dumpster bags use rigid stay structures to maintain shape, then the bag provides structural support, but the bag reduces flexibility and increases storage space requirements
Solution Approach 1:
The patent uses a flexible rim that can dynamically change its configuration - maintaining an extended circular shape during use for structural support, and collapsing to a compact form for storage and transport. This dynamic adaptability replaces rigid structures that cannot change shape.
Solution Approach 2:
The flexible rim constructed from woven material provides the necessary structural support when extended while allowing the bag to be collapsed and stored compactly. The flexible nature of the rim enables both structural integrity during operation and compactness during storage.

AI summary
In a method for using a dumpster bag, the bag comprises: a flexible bag member including a bottom and a sidewall structure extending upward from the bottom to a rim; and a plurality of loops. The method comprises: engaging a hoist to a group of the loops; using the hoist to lift the bag containing contents; releasing the hoist from one or more of the loops; and using the hoist to again lift the bag to discharge the contents from the bag.
