Cleaning device system and method for use
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning devices require high setup times and maintenance when handling mixed media debris, and the process of attaching and detaching replacement heads is cumbersome and messy, often requiring users to get their hands wet or dirty.
Innovation Solution
A cleaning device system with a selectively attachable replacement head featuring a plastic tray with a dust bin and filter, where the device is removably attached by lowering it vertically onto the head, utilizing angled interior walls and connector lips for easy alignment and connection with minimal effort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a non-rigid cleaning sheet is manually wrapped around the mop handle, then the cleaning device can be assembled, but the process requires both hands and is awkward
Solution Approach 1:
The cleaning system is divided into separate modular components: a reusable cleaning device body and disposable replacement heads. This segmentation allows the complex wrapping operation to be replaced by a simple snap-in attachment of pre-assembled replacement heads, eliminating the need for manual sheet wrapping while maintaining functional integrity.
Solution Approach 2:
The patent employs disposable replacement heads that are pre-assembled with cleaning sheets and attachment members. Instead of requiring users to repeatedly assemble and disassemble reusable components, the disposable nature of replacement heads simplifies the attachment process to a single snap-in operation, significantly improving ease of operation.
2Adaptability or versatility
If the cleaning device is designed to handle both dry and wet media, then cleaning versatility is improved, but setup time and maintenance effort increase
Solution Approach 1:
The cleaning device body is designed with universal functionality to handle both dry and wet cleaning tasks. The reusable body contains integrated vacuum and spray capabilities that work with different replacement heads, allowing a single device to perform multiple cleaning functions without requiring separate specialized tools for different media types.
Solution Approach 2:
Replacement heads are pre-assembled at the factory with cleaning sheets, attachment members, and necessary components. This preliminary assembly eliminates the need for users to perform setup operations at home, reducing setup time while maintaining the versatility to handle different cleaning media through appropriately pre-configured replacement heads.
3Adaptability or versatility
If the cleaning device is designed to handle both dry and wet media, then cleaning versatility is improved, but after-use maintenance becomes especially high
Solution Approach 1:
The cleaning system separates maintenance-intensive components (replacement heads with cleaning sheets) from maintenance-free components (reusable device body). This segmentation allows users to simply discard and replace soiled replacement heads rather than cleaning and maintaining the entire device, dramatically reducing maintenance effort while preserving cleaning versatility.
Solution Approach 2:
The patent implements a discard-and-replace strategy for replacement heads that become soiled during use. Instead of requiring users to clean and maintain these components, the disposable nature allows for simple disposal and replacement with fresh heads, eliminating complex maintenance procedures while maintaining the ability to handle various cleaning media.
4Ease of operation
If the replacement head is attached by lowering the cleaning device vertically onto it, then single-handed operation is enabled, but proper alignment must be ensured
Solution Approach 1:
The attachment member and cavity are designed with asymmetric features including angled interior walls and specific connector geometries. These asymmetric design elements create a self-aligning mechanism where the replacement head naturally orients itself correctly during the vertical lowering process, ensuring proper alignment without requiring user skill or two-handed operation.
Solution Approach 2:
The replacement head is pre-positioned on the floor with the attachment member facing upward before the cleaning device is lowered onto it. This preliminary positioning, combined with the self-aligning cavity design, ensures that the vertical lowering motion automatically results in proper alignment and engagement, enabling simple single-handed operation while maintaining alignment precision.

AI summary
A cleaning device is removably attachable to a replacement head. The replacement head includes pad that is attached to the lower side of an attachment member and is in contact with the floor during cleaning. The cleaning device is removably attached to the attachment member of the replacement head by lowering the cleaning device body downward vertically onto the replacement head until a mechanical connection is achieved.
