Dustpan Frame and Filter Layout for Mobile Debris Collection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dustpan designs lack a wheeled garbage bag supporting frame that allows the bag to expand fully, attach to the rear of a dustpan, and include interchangeable filters for efficient debris collection and filtration, while also enabling easy mobilization.
Innovation Solution
A dustpan with a hollow construction and a wheeled garbage bag supporting frame that attaches to the rear of the dustpan, featuring interchangeable filters, a nylon strap for secure attachment, and a roller assembly for upright support, allowing the bag to be used in either vertical or horizontal orientations and enabling easy movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a garbage bag supporting frame is attached to a dustpan, then the bag can be supported in an open position for debris collection, but the device becomes more complex and harder to maneuver
Solution Approach 1:
The patent combines the garbage bag supporting frame with the dustpan by attaching the frame to the rear opening of the dustpan. The frame and dustpan work together as an integrated system where the frame supports the bag and the dustpan collects debris, merging two separate functions into one unified device that simplifies operation.
Solution Approach 2:
The supporting frame serves multiple functions: it holds the garbage bag open for debris collection, provides structural support, and can be attached to or detached from the dustpan. This multi-functionality reduces the need for separate tools and simplifies the overall operation of the debris collection system.
2Ease of operation
If a wheeled running board is added to enable mobilization, then the dustpan becomes easier to move, but the device complexity increases
Solution Approach 1:
The running board with wheels is attached to the bottom of the dustpan, enabling the entire assembly (dustpan, frame, and bag) to be moved easily by a single user. The wheeled design allows the device to roll along the ground, reducing the physical effort required for mobilization and making the system self-sufficient in terms of mobility.
3Productivity
If interchangeable filters are added for debris filtration, then debris collection efficiency is improved, but the device complexity increases
Solution Approach 1:
The filter system is designed as interchangeable components that can be attached to or removed from the dustpan. Multiple filter types can be segmented and swapped based on the specific debris collection needs, allowing efficient filtration while maintaining modularity that reduces overall system complexity.
Solution Approach 2:
The interchangeable filter design allows the system to adapt dynamically to different debris types. Users can change filters based on the collection task, making the system flexible and efficient while keeping the base structure simple and unchanged.
4Quantity of substance
If a hollow construction is used to enable full bag expansion, then the bag capacity is maximized, but the manufacturing complexity increases
Solution Approach 1:
The hollow construction of the dustpan and supporting frame creates nested spaces that allow the garbage bag to expand fully within the frame structure. The frame is positioned inside the hollow dustpan body, creating a nested arrangement that maximizes bag capacity while using a straightforward manufacturing approach for each component.

AI summary
The dustpan with garbage bag supporting frame, filter, and running boards includes a dustpan of hollowed construction from which the garbage bag supporting frame attaches to a rear of said dustpan. The dustpan includes a plurality of interchangeable filters that can attach to a front opening and/or rear opening in order to sift or filter out debris swept into and through said dustpan. The garbage bag supporting frame attaches onto opposing exterior surfaces of said dustpan. Both the garbage bag supporting frame and the dustpan include running boards that attach there under, and which enable mobilization there to. The running board for use with the garbage bag supporting frame may further include an according-styled cover that extends to cover the garbage bag supporting frame as well as a trash bag contained therein.
