Solution Overview
Problem
Current antimicrobial and deodorizing technologies are insufficient in effectively inactivating microorganisms and reducing odors on environmental surfaces, leading to the transmission of infectious diseases, particularly in healthcare settings, due to the persistence of pathogens on surfaces and the limited durability and effectiveness of existing antimicrobial coatings.
Innovation Solution
Development of multifunctional compositions with halogen-stabilizing agents and novel binding systems to immobilize N-halamine compounds on various surfaces, providing potent antimicrobial, deodorizing, and enzyme-inhibiting functions, reducing chlorine odor and gas phase corrosiveness, and enhancing the stability and durability of antimicrobial coatings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If N-halamine compounds are applied to surfaces for antimicrobial function, then microorganism inactivation effectiveness is improved, but chlorine odor and gas phase corrosiveness increase
Solution Approach 1:
The patent uses polymeric binders as intermediary substances to immobilize N-halamine compounds on surfaces. These polymers act as carriers that hold the active antimicrobial agents in place, reducing their volatility and gas phase release while maintaining their biocidal effectiveness against microorganisms.
Solution Approach 2:
The invention creates composite material systems combining N-halamine compounds with polymeric binders and stabilizing agents. This composite approach allows the beneficial antimicrobial properties of N-halamines to be retained while the polymer matrix suppresses chlorine odor and gas phase corrosiveness through physical containment and chemical stabilization.
2Reliability
If existing antimicrobial coatings are applied to surfaces, then some level of microbial protection is provided, but durability and persistence of the coating are insufficient
Solution Approach 1:
The patent applies preliminary stabilization measures by incorporating stabilizing agents and using polymeric binders before the N-halamine compounds are deployed for antimicrobial action. This preliminary bonding and stabilization ensures the coating persists longer on surfaces while maintaining its microbial protection capabilities.
Solution Approach 2:
The polymeric binder system provides continuous attachment of N-halamine compounds to surfaces, ensuring sustained release and prolonged antimicrobial activity. The coating maintains its protective function over extended periods through the continuous presence of the polymer matrix that holds the active ingredients in place.
3Ease of operation
If conventional binding methods are used to apply antimicrobial agents, then application simplicity is maintained, but the stability and durability of the coating are limited
Solution Approach 1:
The patent changes the binding parameters by using polymeric binders with specific molecular weights, functional groups, and adhesive properties. These parameter optimizations in the binder system enhance coating stability and durability while maintaining relatively simple application procedures through dip-coating, spray-coating, or roll-coating methods.
