Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current antiseptic products face limitations due to environmental and health concerns, particularly regarding heat stability and the use of biocides that can cause sensitization or immune stimulation, and they often fail to effectively protect against microbial contamination in aqueous and organic liquids.
Innovation Solution
A process involving the combination of lithium ions and sodium ions, within specific molar ratios, is used to create an antiseptic product that is effective against microbial contamination, providing preservation properties without the need for harmful substances, and maintaining stability at high temperatures and against UV-light.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional biocides are used to protect against microbial contamination, then antimicrobial effectiveness is improved, but environmental harm and health risks (sensitization, immune stimulation) increase
Solution Approach 1:
The patent extracts and eliminates harmful traditional biocides from the composition, replacing them with a safe alternative system based on metal ions (silver, zinc, copper) that provide antimicrobial effectiveness without the sensitization and immune stimulation problems of conventional biocides
Solution Approach 2:
The patent changes the fundamental parameter of antimicrobial agent type from organic biocides to inorganic metal ion systems, altering the mechanism of action while maintaining effectiveness and reducing harmful effects on environment and human health
2Productivity
If heat treatment is applied to improve processing, then manufacturing efficiency is improved, but antiseptic compound stability deteriorates at temperatures above 100°C
Solution Approach 1:
The patent changes the thermal stability parameter by replacing heat-sensitive organic biocides with thermally stable inorganic metal ion compounds that maintain their antiseptic properties through high-temperature processing stages
Solution Approach 2:
The patent applies antiseptic treatment in advance at lower temperatures before subsequent high-temperature processing steps, ensuring microbial protection is established before thermal degradation could occur
3Ease of manufacture
If polymer processing is performed to create final products, then product formation is improved, but antiseptic compound stability deteriorates at temperatures of 100-270°C
Solution Approach 1:
The patent changes the chemical composition parameter to use polymer-compatible, thermally stable inorganic metal ion antiseptics that do not degrade or react adversely during polymer processing at 100-270°C, maintaining effectiveness throughout the manufacturing cycle
