Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing floor cleaning attachments face issues with incorrect alignment of cleaning cloths, manual handling, and perceived unhygiene due to manual replacement, as well as potential suction opening obstruction and imbalance.
Innovation Solution
The device employs magnetic and/or snap connections for detachable coupling of cleaning units to the housing, featuring actuating elements for easy detachment and a design with separate suction openings to prevent misalignment and improve durability and hygiene.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a detachable hook-and-loop fastener is used to attach the cleaning cloth, then easy removal and reattachment is achieved, but precise alignment of the cleaning cloth cannot be guaranteed
Solution Approach 1:
The patent replaces the mechanical hook-and-loop fastener system with a magnetic field-based connection system. The magnetic connection automatically guides the cleaning unit into precise alignment with the housing during attachment, eliminating positioning errors while maintaining easy attach/detach operation. The magnetic force provides both the attachment mechanism and the alignment guidance simultaneously.
2Ease of operation
If the cleaning cloth is manually held for removal, then the attachment can be detached, but user convenience is reduced and hygiene concerns arise
Solution Approach 1:
The patent implements a self-service mechanism where the cleaning unit automatically ejects itself from the housing when the drive unit rotates in reverse. The magnetic connection is designed to be overcome by the centrifugal force generated during reverse rotation, causing the cleaning unit to be automatically thrown off without requiring manual intervention. This eliminates the need for users to manually handle and remove the cleaning unit.
3Ease of repair
If the receiving element is detachably connected to the housing, then easy maintenance is achieved, but misalignment and imbalance problems can occur
Solution Approach 1:
The patent replaces traditional mechanical alignment features (such as guide rails or positioning pins) with a magnetic field-based alignment system. The magnetic attraction force automatically centers the cleaning unit relative to the housing during attachment, ensuring precise alignment without requiring complex mechanical guidance structures. This maintains reliability while preserving ease of maintenance.
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
Ensures precise alignment, simplifies attachment and detachment, reduces manual handling, and minimizes suction obstruction, enhancing cleaning efficiency and user convenience.
Implementation Method 1
the first and second connecting elements can be connected to one another by means of a magnetic connection. When the connecting elements are coupled, they move into a predefined position, thus assuming a centering function. As the connecting elements approach each other, the attractive forces of the magnets cause them to move 'by themselves' into the predefined position
