Bare Floor Vacuum Agitator and Chamber for Low-Energy Debris Pickup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vacuum cleaners often require continuous suction power to effectively ingest debris, which can be inefficient and inconvenient for quick clean-ups or navigating tight spaces, and may not efficiently manage debris outside the suction path.
Innovation Solution
The vacuum cleaner incorporates counter-rotating agitators on a foot assembly with a focused suction aperture and an intermediate collection chamber, allowing for manual operation without suction to collect debris, which can then be ingested by activating the suction source, and features a compact design with a reduced suction inlet diameter for improved energy efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If continuous suction power is used to ingest debris, then debris ingestion effectiveness is improved, but energy consumption increases
Solution Approach 1:
The agitators perform preliminary action by dislodging and transporting debris to the suction aperture before suction is activated. This mechanical pre-positioning of debris reduces the power needed for actual ingestion, as the suction source only needs to collect already-positioned debris rather than pull it from across the surface.
Solution Approach 2:
The cleaning function is segmented into two distinct phases: mechanical agitation/transport phase (low energy) and suction ingestion phase (higher energy). The agitators handle the bulk of debris movement manually or with minimal power, while the suction source is activated only when needed for final collection, separating the continuous high-energy operation from the cleaning task.
2Productivity
If suction power is activated for quick clean-ups, then debris removal speed is improved, but energy efficiency deteriorates
Solution Approach 1:
For quick clean-ups, the agitators can rapidly transport debris to the suction aperture using manual propulsion or brief agitation, preparing the debris for immediate ingestion. This allows the suction source to be activated only for the brief moment needed to collect the pre-positioned debris, maintaining high removal speed while minimizing energy consumption during the quick clean-up task.
3Quantity of substance
If a wide suction aperture is used to collect debris, then debris collection capacity is improved, but power consumption increases
Solution Approach 1:
The agitators perform preliminary action by collecting and transporting debris to the suction aperture before suction is activated. This mechanical pre-concentration of debris at the aperture means the suction source only needs to handle a focused stream of already-collected material, allowing for a narrower, more energy-efficient aperture while maintaining high debris collection capacity through the combined action of agitation and targeted suction.
4Productivity
If the vacuum cleaner is designed for powered operation, then cleaning effectiveness is improved, but adaptability to environments without electricity deteriorates
Solution Approach 1:
The vacuum cleaner is designed with dual functionality: the agitators can operate manually through user propulsion to perform sweeping and debris transport without electricity, while the same device can be activated with power for enhanced suction and cleaning effectiveness. This multi-functionality allows the device to adapt to both powered and unpowered environments, making it versatile for different usage scenarios.

Implementation Method 1
a suction source to produce a working airflow... when the suction source is active, the suction source draws debris through the suction inlet, along the working conduit for collection into the dirt container
Implementation Method 2
manual movement of the housing over the surface being cleaned rotates the at least one agitator and transports debris removed from the surface being cleaned by the agitator into the suction inlet

AI summary
A vacuum cleaner for removing dirt from a surface includes a housing mounted to a handle assembly or wand assembly includes a dirt container positioned in at least one of the handle assembly, wand assembly, or housing. A working air conduit extends from a suction inlet of the vacuum cleaner and the dirt container, wherein, when the suction source is active, the suction source draws debris through the suction inlet, along the working conduit for collection into the dirt container, wherein a portion of the working air conduit forms an intermediate collection chamber, the intermediate collection chamber being removable from a stored position in the housing.
