Disposable Vacuum Cleaning Head With Sealed Wet-Dry Dirt Chamber
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning devices often require multiple tools and processes to handle both wet and dry debris, leading to inefficiencies, mess, and high maintenance, as they are typically suited for either wet or dry media, and may not capture all types of debris effectively.
Innovation Solution
A cleaning device with a removably attachable cleaning head featuring a permanently attached dirt collection chamber that can absorb and contain both wet and dry debris, eliminating the need for users to handle the dirty head and allowing for easy disposal without opening the chamber, which is made of absorptive but impermeable material and includes air filtration for effective debris management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional cleaning device with separate wet and dry cleaning components is used, then both wet and dry debris can be cleaned, but the device complexity increases and requires multiple tools
Solution Approach 1:
The cleaning system is segmented into a reusable vacuum body and disposable cleaning heads. Each cleaning head is a separate, self-contained unit that can be easily attached and detached, allowing the user to switch between different cleaning head types (wet vs. dry) without changing the main device structure.
Solution Approach 2:
The vacuum body is designed as a universal platform that can accommodate multiple types of cleaning heads through a standardized attachment mechanism. This allows a single vacuum body to perform both wet and dry cleaning functions by simply changing the cleaning head accessory.
2Duration of action of stationary object
If a reusable dirt collection chamber is used, then the device can be used multiple times, but maintenance and cleaning of the chamber becomes complicated and time-consuming
Solution Approach 1:
The cleaning head including the dirt collection chamber is designed as a disposable component. After use, the entire cleaning head with accumulated dirt is discarded and replaced with a fresh one, eliminating the need for users to manually empty, clean, or maintain the dirt collection chamber.
Solution Approach 2:
The dirt collection chamber is extracted as part of the disposable cleaning head assembly rather than being a separate permanent component of the vacuum. This allows the dirt chamber to be removed along with the cleaning head in a single action, simplifying disposal.
3Loss of substance
If the dirt collection chamber is made openable for disposal, then dirt can be removed and reused, but the structure becomes more complex and may compromise sealing
Solution Approach 1:
The dirt collection chamber is designed as a sealed, non-openable container within the disposable cleaning head. Since the entire cleaning head is discarded after use, there is no need for openings or complex mechanisms to remove dirt - the simplest sealed structure is used, reducing complexity while achieving the disposal function through replacement rather than emptying.
4Device complexity
If a single cleaning head is used for both wet and dry debris, then the device is simpler, but it may not effectively capture all types of debris
Solution Approach 1:
Different cleaning heads are segmented into specialized designs optimized for specific debris types (wet vs. dry). Each cleaning head has tailored features such as appropriate filtration, suction nozzle design, and structural characteristics for its intended purpose, ensuring effective performance for each debris type.
Solution Approach 2:
Each cleaning head is designed with local quality - specific features and materials optimized for its intended function. For example, dry cleaning heads may have different filtration and airflow characteristics compared to wet cleaning heads, allowing each to perform its specific function effectively while maintaining overall system simplicity through standardized mounting.
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
The solution allows for efficient cleaning of both wet and dry debris with a single device, reducing the need for multiple tools, minimizing user contact with dirty components, and maintaining the cleanliness of the device throughout operation by containing debris within the disposable cleaning head.

AI summary
Methods and apparatus for cleaning a surface with a cleaning device having a body with a handle, a connector, and one or more cleaning heads that are removably attached to the cleaning device. Each cleaning head include a lower surface arranged to contact a surface to be cleaned and a dirt collection chamber permanently attached to the cleaning head. The cleaning head may include a support structure to support the dirt collection chamber and a cleaning sheet. The cleaning head also may include a suction nozzle. At least a portion of the dirt collection chamber may be made of a filter material.
