Vacuum Duster Fiber Assembly for Directed Dust Pickup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning and dusting devices with integrated vacuums are often complex, expensive, and cumbersome for extended use, lacking a compact and efficient solution for single-handed operation with enhanced dust removal capabilities.
Innovation Solution
A handheld dust removal device with a small, lightweight handle housing an electric motor and battery, featuring elongate fiber strands with voids that direct and influence vacuum airflow to dislodge and collect dust and debris, including an auxiliary vacuum inlet for larger particles, allowing for extended use without user fatigue.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If vacuum features are integrated into cleaning tools, then dust removal capability is improved, but device complexity increases
Solution Approach 1:
The patent combines the vacuum motor, dust collection chamber, and cleaning tool functions into a single integrated device. The motor housing serves as both the structural enclosure and the dust collection chamber, eliminating the need for separate vacuum cleaner and dustpan components. This merging approach maintains enhanced dust removal capability while reducing overall device complexity.
Solution Approach 2:
The handle assembly serves multiple functions: it provides structural support, houses the motor and battery, collects dust, and enables handheld operation. The hollow handle acts as both a grip and a dust collection chamber, allowing the device to perform cleaning and dust collection simultaneously with a single unified structure.
2Productivity
If vacuum assembly is integrated into handle, then dust collection is improved, but weight increases
Solution Approach 1:
The vacuum motor and dust collection chamber are nested within the handle assembly structure. The motor housing is positioned inside the hollow handle, and the dust collection chamber is formed within the same structural envelope. This nesting approach allows dust collection functionality to be incorporated without adding external components that would increase overall device weight.
3Ease of operation
If elongate fiber strands with voids are used, then vacuum airflow direction is improved, but manufacturing complexity increases
Solution Approach 1:
The fiber strands are designed with elongate voids running through them, creating a porous structure that allows vacuum airflow to pass through and be directed along the fibers. This porous configuration enables the fibers to both mechanically contact surfaces and pneumatically direct airflow, improving dust dislodging and collection efficiency while using a relatively simple extrusion or molding process to create the voided structure.

AI summary
Handheld dust removal devices that selectively utilize vacuum pressure are disclosed. Preferably, each device includes a small lightweight handle that houses a vacuum assembly having an electric motor and a battery. The device further includes a duster assembly with elongate fiber strands that have elongate voids extending therethrough or thereinto. The vacuum source can be fluidly connected to and draw a vacuum airflow through the duster assembly, for example, through and/or around the fiber strands. In such configuration, the elongate voids of the fiber strands can at least partially direct or influence the travel path of dust, debris, and/or other particulates that are entrained in a vacuum airflow. Some implementations further include an auxiliary vacuum inlet that is adapted and configured for drawing large particles such as crumbs, hair, and others thereinto. The auxiliary vacuum port can be displaced from the duster assembly, e.g., mounted to the handle or elsewhere.
