Antimicrobial Porous Matrix Composite Without Chemical Leaching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cleaning products, such as sponges and mops, often become incubators for microbes due to moisture and food residues, leading to contamination and the spread of harmful bacteria, with existing antimicrobial solutions being toxic and non-effective in the long term.
Innovation Solution
A method for manufacturing non-leaching antimicrobial porous composites by mixing a solidifiable matrix with a non-leachable antimicrobial and a removable pore-forming substance, then removing the substance to create pores and physically incorporating the antimicrobial within the matrix, ensuring the antimicrobial remains effective and non-toxic.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If spray-on microbiostatic agents (quaternary amines) are used to slow microbe growth, then antimicrobial protection is provided, but the chemicals are toxic and leach out over time, losing effectiveness
Solution Approach 1:
The patent extracts the harmful chemical component (quaternary amines) from the system and replaces it with a physical structure (porous matrix with embedded antimicrobial particles) that provides antimicrobial action without chemical leaching. The antimicrobial particles are physically incorporated into the porous structure, allowing them to remain in place while providing continuous protection.
Solution Approach 2:
The patent uses a porous matrix structure that physically incorporates antimicrobial particles within its pores. This porous structure allows the antimicrobial particles to be retained in place rather than leaching out, while still providing antimicrobial protection through physical contact with microbes that enter the pores during normal use.
2Productivity
If porous absorbent materials are used for cleaning, then absorption and cleaning effectiveness is improved, but the material becomes a microbe incubator due to moisture and food residues
Solution Approach 1:
The patent merges the absorbent porous matrix function with the antimicrobial particle function into a single composite material. The porous structure provides absorption and cleaning effectiveness, while the embedded antimicrobial particles simultaneously prevent microbe growth, eliminating the need for separate antimicrobial treatment.
Solution Approach 2:
The composite material provides self-service by incorporating antimicrobial particles that automatically prevent microbe growth as microbes come into contact with the material during normal cleaning use. No additional chemicals or treatments are needed—the structure itself provides continuous antimicrobial protection.
3Duration of action of stationary object
If antimicrobial particles are physically incorporated into the porous matrix, then the antimicrobial properties are maintained over time without leaching, but the manufacturing process becomes more complex
Solution Approach 1:
The patent applies preliminary action by incorporating the antimicrobial particles into the porous matrix during the manufacturing process, before the product is put into service. This ensures the antimicrobial particles are permanently embedded in the structure, providing long-lasting protection without requiring subsequent treatments or applications.

Function Achieved in This Case
The solution creates a durable, effective antimicrobial surface that prevents microbial growth and contamination, maintaining its properties over time without leaching harmful chemicals, thus providing health and environmental safety.
Implementation Method 1
removing the pore-forming substance from the solid matrix by subjecting the solidified matrix to physical conditions that remove the solid pore-forming substance such as by melting or dissolution
Implementation Method 2
removing the pore-forming substance from the solid matrix by subjecting the solidified matrix to physical conditions that remove the solid pore-forming substance such as by melting or dissolution
Implementation Method 3
a non-leachable antimicrobial physically incorporated and thus composited within this matrix through physical anchoring
