Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods are inadequate in protecting surfaces and polymeric materials from viral contamination, as they lack effective antiviral properties against a wide range of viruses.
Innovation Solution
Development of antiviral surfaces and compositions by modifying polymeric molecules with specific compounds, such as those represented by formulas (I) and (II), which are covalently bonded or embedded in materials to provide antiviral activity, including the use of diazabicyclo[2.2.2]octane derivatives and modified polyols, ensuring charge balance and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional surfaces and polymeric materials are used, then they maintain simplicity and ease of manufacture, but they lack effective antiviral properties against a wide range of viruses
Solution Approach 1:
The patent modifies surfaces by changing chemical parameters - specifically by introducing quaternary ammonium groups and other cationic moieties onto polymeric surfaces. This chemical parameter change provides broad-spectrum antiviral activity while maintaining the base polymer structure, thus improving reliability without excessive complexity
Solution Approach 2:
The invention creates composite surfaces by combining polymeric materials with antiviral agents (quaternary ammonium compounds, diazabicyclo[2.2.2]octane derivatives). These composite structures integrate the mechanical properties of the polymer with the antiviral functionality of the embedded compounds, achieving both durability and antiviral efficacy
2Reliability
If antiviral compounds are covalently bonded or embedded in polymeric materials, then antiviral activity is provided, but the manufacturing process becomes more complex
Solution Approach 1:
The patent employs preliminary action by pre-synthesizing antiviral compounds with specific functional groups (quaternary ammonium, diazabicyclo[2.2.2]octane derivatives) that are designed to bond with polymeric materials. These pre-prepared compounds are then easily incorporated into the polymer matrix through straightforward processes like coating, embedding, or covalent bonding, reducing manufacturing complexity
Solution Approach 2:
The invention uses small-molecule antiviral compounds that can be applied as coatings or embedded in polymers. These compounds provide antiviral protection without requiring complex structural changes to the base material, allowing for relatively simple manufacturing processes while maintaining effective antiviral activity
