Mop Head Abrasive Strip Layout for Larger Floor Contact
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mop heads with abrasive bodies either have limited contact with the floor due to being covered by cleaning strips or protrude radially, resulting in a small contact area, making it difficult to effectively clean firmly adhering dirt.
Innovation Solution
An abrasive body is cemented onto the cleaning strips, designed to hang down from the mop head, allowing for a larger contact area and improved ergonomic cleaning by being positioned between the mop head and cleaning strips, which can be made of various materials like polyacrylate fibers or polyurethane foam, secured with an adhesive agent like low-melting polyethylene.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the abrasive body is located below the cleaning strips, then it is protected from damage, but it is difficult to bring into contact with the floor to be cleaned since it is mostly covered by cleaning strips
Solution Approach 1:
The abrasive body is segmented into multiple sections arranged along the cleaning strips, with each section capable of contacting the floor independently. This segmentation allows the abrasive body to maintain protection while enabling multiple contact points with the floor surface.
Solution Approach 2:
The abrasive body is arranged to extend in the longitudinal direction of the cleaning strips, transitioning from a single radial contact point to multiple contact points distributed along the length of the strips. This dimensional arrangement allows the abrasive body to contact the floor at multiple locations simultaneously.
2Device complexity
If the abrasive body is located between the mop head and the cleaning strips, then it sticks out mostly radially from the mop head, but in this way it also can be difficult to bring into contact with the floor to be cleaned and only provides a small contact area
Solution Approach 1:
The abrasive body is divided into multiple sections distributed along the cleaning strips, creating multiple contact zones with the floor. This segmentation transforms a single small contact area into multiple distributed contact areas, significantly increasing the total contact surface.
Solution Approach 2:
The abrasive body extends in the longitudinal direction of the cleaning strips rather than only radially outward. This dimensional extension along the length of the strips increases the contact area by utilizing the longitudinal dimension in addition to the radial dimension.
3Ease of operation
If the abrasive body is designed to hang down with the cleaning strip, then it can be brought into contact simply and with a large contact area with the floor to be cleaned, but the abrasive body needs to be securely affixed to the cleaning strip
Solution Approach 1:
The abrasive body is pre-formed with attachment features or surface characteristics that facilitate secure bonding to the cleaning strips. This preliminary preparation simplifies the affixing process during assembly while ensuring reliable attachment.
Solution Approach 2:
The abrasive body utilizes composite material construction combining abrasive particles with a binding matrix that also provides attachment capability to the cleaning strips. This composite structure integrates the abrasive function with the attachment function, simplifying the affixing process.
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 configuration enables efficient removal of firmly adhering dirt with a larger contact area and improved ergonomic handling, suitable for both hard and sensitive surfaces.
Implementation Method 1
The abrasive body can be secured on the at least one cleaning strip with an adhesive agent. The adhesive agent produces a firm and material-locking connection of the abrasive body and the cleaning strips.
Implementation Method 2
If the abrasive body consists of polyacrylate fibers, then they are preferably applied using a solution-containing polyacrylate, for example, sprayed on and fixed there.
