Antimicrobial Substrate Composite with Water-Repellent Layer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional substrates lack effective antimicrobial and antiviral protective characteristics, leading to the transfer of microbial agents from person to person and from substrate to substrate.
Innovation Solution
An antimicrobial system comprising an outermost layer with an antimicrobial compound and a water-repellent layer, where the antimicrobial compound includes a solution of 47% ammonium sulfate, 42% water, and 11% other components, such as surfactants and metallic sulfates, with a resultant pH of 5-6.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional substrates are used, then manufacturing simplicity is maintained, but antimicrobial and antiviral protective characteristics are lacking
Solution Approach 1:
The patent applies composite materials by combining a substrate with multiple functional layers including a water-repellent layer containing hydrophobic substances and an antimicrobial layer containing antimicrobial compounds. This composite structure provides both antimicrobial protection and water-repellent properties while maintaining substrate functionality, resolving the contradiction between protective characteristics and structural complexity.
Solution Approach 2:
The patent segments the protective system into distinct functional layers: a water-repellent layer and an antimicrobial layer, each performing specific functions. This segmentation allows optimization of each layer's properties independently while maintaining overall system effectiveness, addressing the contradiction between achieving multiple protective functions and maintaining simplicity.
2Object-affected harmful factors
If no water-repellent layer is applied, then manufacturing process remains simple, but liquid phase transfer between substrates occurs
Solution Approach 1:
The patent extracts the water-repellent function into a separate functional layer containing hydrophobic substances, distinct from the substrate and antimicrobial layers. This extraction allows the water-repellent property to be added without fundamentally changing the substrate manufacturing process, addressing the contradiction between preventing liquid transfer and maintaining ease of manufacture.
3Object-affected harmful factors
If antimicrobial compounds are not incorporated, then manufacturing cost and complexity remain low, but microbial agent transfer occurs
Solution Approach 1:
The patent incorporates antimicrobial compounds into the substrate structure in advance, creating a pre-protected substrate that actively prevents microbial agent transfer. This preliminary incorporation of protective functionality resolves the contradiction between eliminating microbial transfer and maintaining simple substrate composition.
