Solution Overview

Problem

Conventional cleaning tools like abrasive blankets and sponges lack effective antimicrobial properties to combat the growth and proliferation of viruses and bacteria, particularly in the context of increased surface contamination during epidemics like COVID-19.

Innovation Solution

Development of antiviral and antibacterial abrasive blankets and sponges comprising non-abrasive non-woven fabrics treated with polymeric emulsions containing antiviral and antibacterial agents, along with abrasive grains, which are processed to enhance durability and efficacy in neutralizing or eliminating pathogens.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional cleaning tools are used, then cleaning function is provided, but antimicrobial protection is lacking

Engineering Contradiction:

Improveantimicrobial protectionVSAvoidmicroorganism growth

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent applies preliminary action by incorporating antiviral and antibacterial agents into the cleaning tool materials before use. The non-woven fabric is treated with polymeric emulsions containing antimicrobial agents during manufacturing, creating pre-protected surfaces that actively combat microorganisms from the first contact, rather than requiring subsequent treatment or replacement

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent uses composite materials by combining non-woven fabric, polymeric emulsions, abrasive grains, and antiviral/antibacterial agents into an integrated cleaning tool. This composite structure provides both cleaning functionality and sustained antimicrobial protection, with the polymeric emulsion serving as a binding matrix that holds abrasive and antimicrobial components in place on the fabric substrate

Inventive Principle:

Principle #40Composite materials

2Reliability

If antimicrobial agents are added to cleaning tools, then microbial resistance is reduced, but manufacturing complexity increases

Engineering Contradiction:

Improvemicrobial resistanceVSAvoidmanufacturing process

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent merges multiple functions into a single integrated manufacturing process. The polymeric emulsion application step simultaneously imparts antimicrobial properties, abrasive cleaning capability, and surface binding in one treatment stage. This consolidation reduces manufacturing complexity compared to separate treatment steps for each function

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent applies parameter changes by modifying the chemical composition and physical state of the cleaning tool surface through polymeric emulsion treatment. The emulsion transforms from a liquid application form to a cured polymeric matrix, changing properties such as hardness, adhesion, and antimicrobial activity. This parameter transformation enables multi-functionality without requiring complex assembly processes

Inventive Principle:

Principle #35Parameter changes
