Unitary Cleaning Sheet and Air Filter for Clog-Free Airflow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning devices with disposable cloths face inefficiencies in debris collection and sanitation, as the process of emptying dirt bins and disposing of soiled cloths can be unsanitary and inconvenient, especially when filters become clogged, reducing airflow and cleaning effectiveness.
Innovation Solution
A cleaning implement with a unitary cleaning sheet and air filter, where the sheet serves both as a cleaning surface and a filter, attached to the head, allowing for easy disposal of soiled components in a single operation, enhancing sanitation and convenience by integrating the filter with the cleaning cloth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate air filter is used in the airflow path, then debris removal from air flow is improved, but device complexity and maintenance difficulty increase due to separate filter replacement
Solution Approach 1:
The patent combines the air filter with the cleaning sheet into a single integrated component. The filter is positioned at the rear portion of the sheet and is removed together with the sheet after use, eliminating the need for separate filter maintenance and reducing device complexity while maintaining effective debris removal from the airflow path
2Object-affected harmful factors
If the cleaning sheet is disposable and removed after each use, then sanitation is improved, but loss of time increases due to repeated removal and disposal operations
Solution Approach 1:
By integrating the filter with the cleaning sheet, the patent enables both components to be removed and disposed of in a single operation. This combination maintains the sanitation benefits of disposable sheets while eliminating the time loss associated with separate filter replacement, as users discard both the soiled sheet and accumulated filter debris together
3Ease of repair
If the air filter is disposed of separately from the cleaning sheet, then filter maintenance is improved, but ease of operation deteriorates due to multiple disposal trips
Solution Approach 1:
The integrated design allows the filter to be positioned on the cleaning sheet such that both are removed together from the housing. This merging maintains proper filter maintenance while dramatically improving ease of operation, as users make only one disposal trip instead of multiple trips to discard the sheet and filter separately
4Reliability
If a porous filter media is used to remove debris from airflow, then air flow filtration is improved, but airflow resistance increases reducing cleaning effectiveness
Solution Approach 1:
The patent segments the sheet into functional zones: a cleaning surface area for contact with the target surface and a separate porous filter portion positioned in the airflow path. This segmentation allows the filter to be optimized for debris capture while the main sheet body maintains cleaning effectiveness, and the integrated design ensures both are replaced together when the filter becomes clogged
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design ensures that the air filter is changed along with the cleaning cloth after each use, maintaining airflow efficiency and simplifying the disposal process, using inexpensive materials without compromising performance, and providing a more sanitary and ergonomic solution for debris and filter disposal.
Implementation Method 1
a source of vacuum for moving debris from the surface to the dirt bin via an airflow path
Implementation Method 2
an air filter disposed in said airflow path for removing debris therefrom
Data Source
AI summary
A cleaning implement having a dirt bin for collecting debris from a floor, a cleaning sheet and an air filter. The cleaning sheet and air filter comprise a unitary assembly. When the user discards a soiled sheet, the soiled air filter is likewise discarded. This process prevents the air filter from becoming unduly clogged, and diminishing the performance of the cleaning implement.
