Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fiber materials used in antibacterial and antiviral filters and mouth/nose protectors face issues with reactive oxygen species (ROS) generated by metallic silver and manganese(IV) oxide, which can be harmful if inhaled in large quantities, as they are not effectively neutralized within the materials.
Innovation Solution
A fiber material composite with a first region comprising metallic silver and manganese(IV) oxide to produce ROS and a second region configured to neutralize these species, using electrically conducting materials like stainless steel to facilitate electron exchange and minimize ROS exposure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If metallic silver and manganese(IV) oxide are applied to fibers to produce reactive oxygen species for antibacterial and antiviral effects, then the antibacterial and antiviral performance is improved, but harmful reactive oxygen species are generated that can be inhaled and cause damage
Solution Approach 1:
The filter material is divided into two distinct functional regions: a first region containing metallic silver and manganese(IV) oxide for ROS production, and a second region containing electrically conducting material for ROS neutralization. This spatial segmentation allows each region to perform its specific function independently, maintaining antibacterial/viral efficacy while protecting against harmful ROS inhalation.
Solution Approach 2:
The second region with electrically conducting material acts as an intermediary between the ROS-producing first region and the wearer's respiratory system. This intermediate layer neutralizes harmful ROS through electron exchange before they can reach the wearer, while still allowing beneficial antimicrobial ROS to function in the first region.
2Object-affected harmful factors
If a second region with electrically conducting material is added to neutralize reactive oxygen species, then the safety and compatibility are improved, but the device complexity increases
Solution Approach 1:
The patent combines multiple functions into a single integrated filter material composite: filtration, ROS production for antimicrobial action, and ROS neutralization for safety. By merging these functions into one composite structure with two regions, the design avoids the complexity of multiple separate components while achieving all necessary functions.
Solution Approach 2:
The first region with metallic silver and manganese(IV) oxide serves multiple purposes: it provides structural support as part of the filter material, generates ROS for antibacterial and antiviral effects, and works in conjunction with the second region to create a safe, effective filtration system. The electrically conducting material in the second region similarly serves both as a structural component and as the active neutralization agent.
