Floor cleaning pad
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning pads are inadequate for modern wood and laminate floors due to their unique hydrophobic surface wettability, leading to streaks and residue issues, as they tend to de-wet quickly and leave behind dirt and cleaning solution, which are visually noticeable due to their dark and shiny nature.
Innovation Solution
A cleaning pad with a floor sheet comprising multiple regions of absorbent materials, including a relatively medium absorbency material and one or both of relatively low and high absorbency materials, strategically arranged to balance absorbency and sliding resistance, preventing wet collapse and enhancing debris trapping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a cleaning pad with high absorbency is used on modern wood and laminate floors, then the pad can absorb cleaning solution, but the pad de-wets quickly and leaves streaks and residue due to the hydrophobic surface
Solution Approach 1:
The cleaning pad incorporates regions with different absorbency characteristics (high, medium, and low absorbency materials) to match different functional requirements. High absorbency regions capture cleaning solution and soil, while low absorbency regions maintain contact with the hydrophobic floor surface without de-wetting, preventing streaks and residue formation.
Solution Approach 2:
The cleaning pad uses a composite structure combining multiple absorbent materials with different properties (e.g., highly absorbent materials like rayon or cotton with less absorbent materials like polyester or polypropylene). This composite approach allows the pad to simultaneously achieve high solution absorption and maintain stable contact with hydrophobic surfaces.
2Quantity of substance
If a cleaning pad with high absorbency material is used, then the pad can lift spent detergent solution from the floor, but the pad becomes overly saturated and loses sliding ability
Solution Approach 1:
Different regions of the cleaning pad have different absorbency levels optimized for specific functions. High absorbency regions are positioned where solution pickup is needed, while low absorbency regions are positioned to maintain sliding capability and prevent the entire pad from becoming overly saturated and stuck.
Solution Approach 2:
The cleaning pad is divided into multiple regions with different material compositions and absorbency characteristics. This segmentation allows the pad to perform multiple functions simultaneously: high absorbency zones capture and hold cleaning solution, while low absorbency zones maintain friction characteristics necessary for easy sliding across the floor surface.
3Device complexity
If a cleaning pad with uniform absorbency is used, then the pad structure is simple, but it cannot effectively address the unique hydrophobic surface wettability of modern wood and laminate floors
Solution Approach 1:
The cleaning pad features non-uniform absorbency distribution with distinct regions of high, medium, and low absorbency materials. This local differentiation allows the pad to adapt to the hydrophobic surface characteristics of modern wood and laminate floors, with low absorbency regions maintaining stable contact and high absorbency regions capturing cleaning solution and soil effectively.
Solution Approach 2:
The cleaning pad varies the absorbency parameter across different regions by using materials with different fiber compositions and structures. High absorbency materials (e.g., rayon, cotton) are used in regions where solution uptake is needed, while low absorbency materials (e.g., polyester, polypropylene) are used in regions requiring stable surface contact, creating a gradient that optimizes performance on hydrophobic surfaces.
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 cleaning pad effectively lifts spent detergent solution and soil from the floor without leaving residue, maintaining maneuverability and reducing streaks and film formation, thus providing better cleaning performance on hydrophobic surfaces.
Implementation Method 1
The liquids may be absorbed from hard surfaces, such as floor and countertops
Implementation Method 2
The absorbent cleaning pad can have an absorbent capacity that is large enough to treat an appreciable surface area
Implementation Method 3
Modern wood and laminates are up to three times more hydrophobic compared to a ceramic floor
Implementation Method 4
Contact angle is the angle, conventionally measured through the liquid, where a liquid/vapor interface meets a solid surface. It quantifies the wettability of a solid surface by a liquid

AI summary
A cleaning pad including a floor sheet, wherein said floor sheet has at least two regions of absorbent materials including a first region having a relatively medium absorbency material and a second region, wherein the second region includes one or both of a relatively low absorbency material and a relatively high absorbency material. The first region and said second region together have a combined planar area. The first region constitutes from more than 30% to 65% of the combined planar area. The second region constitutes from 30% to less than 60% of the combined planar area. The first region and the second region form a substantially coplanar floor engaging surface.
