Cleaning wet wipe
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cleaning wet wipes struggle to effectively remove oil and liquid stains from surfaces, particularly in kitchen areas, due to inadequate wiping performance.
Innovation Solution
A cleaning wet wipe is developed by impregnating a base paper sheet with a chemical agent having a pH of 8.0 to 9.0, containing 0.05% to 0.15% polyoxyethylene alkyl ether and 5.0% to 15.0% ethanol, and featuring embossment patterns with convex and concave shapes arranged in diamond configurations, along with a non-embossment area proportion of 25% to 50%, to enhance dirt scraping and chemical agent discharge properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a special chemical agent is impregnated into the sheet to improve wiping performance, then general cleaning ability is improved, but wiping performance against oil stains and liquid stains remains insufficient
Solution Approach 1:
The patent changes the chemical parameters of the cleaning agent by specifying a pH range of 8.0-9.0 and particular concentrations of polyoxyethylene alkyl ether (0.05-0.15% by mass) and ethanol (5.00-15.00% by mass). These parameter optimizations enable effective removal of oil and liquid stains while maintaining composition simplicity
Solution Approach 2:
The patent creates a composite chemical formulation combining polyoxyethylene alkyl ether (surfactant) with ethanol (organic solvent) in specific proportions. This composite approach leverages the synergistic effects of both components to tackle stubborn stains that neither substance could remove alone
2Reliability
If embossments are added to enhance dirt scraping, then wiping performance is improved, but the structure becomes more complex
Solution Approach 1:
The patent segments the embossment structure into distinct functional zones: embossment blocks containing convex embossments for scraping dirt, concave embossments for trapping particles, and non-embossment parts for chemical agent discharge. This segmentation allows each zone to perform its specific function optimally
Solution Approach 2:
The patent applies local quality by creating regions with different surface properties - raised convex areas for mechanical scraping, depressed concave areas for particle collection, and flat non-embossment areas for chemical action. Each local region is optimized for its specific cleaning function
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 significantly improves the wiping performance against oil and liquid stains by reducing wiping streaks, enhancing dirt scraping, and suppressing surface deterioration, while maintaining effective chemical agent distribution and dust capturing properties.
Implementation Method 1
the chemical agent has a hydrogen ion exponent of 8.0 to 9.0 and contains 0.05% by mass to 0.15% by mass of polyoxyethylene alkyl ether and 5.00% by mass to 15.00% by mass of ethanol
Implementation Method 2
contains 0.05% by mass to 0.15% by mass of polyoxyethylene alkyl ether and 5.00% by mass to 15.00% by mass of ethanol
Implementation Method 3
Embossment blocks in each of which a plurality of convex embossments that are embossments having convexity in a first surface of the cleaning wet wipe are gathered
Implementation Method 4
the embossment blocks which are a plurality of embossment blocks are continuously arranged and form embossment block rows from a first side to a second side opposite to the first side
