Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current respiratory viral pathogen testing is inefficient and costly, particularly for asymptomatic individuals, and during pandemics, due to time delays and limitations in detection agent development, leading to potential disease spread from undetected asymptomatic carriers.
Innovation Solution
A rapid testing mechanism using a filter material impregnated with a pathogen binding adsorptive reagent that captures exhaled breath particles, providing a quick and qualitative assessment by reacting to viral pathogens, indicated by color changes, allowing for immediate detection without the need for advanced technology or labor-intensive processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional viral testing methods are used to identify specific viruses, then epidemiological data can be collected and targeted treatment can be provided, but testing causes unnecessary cost and burden on the healthcare system for the vast majority of respiratory viruses where specific identification provides little benefit
Solution Approach 1:
The patent extracts the essential detection function from complex conventional testing methods by using a filter material impregnated with pathogen-binding adsorptive reagent that directly captures viral particles from breath condensate, eliminating the need for elaborate sample processing and specific virus identification procedures while maintaining detection capability
Solution Approach 2:
The filter material serves multiple functions simultaneously: it captures viral particles from breath condensate, provides a surface for pathogen-binding reagent interaction, and enables visual detection through color change, creating a universal testing platform that works for various respiratory viruses without requiring virus-specific procedures
2Measurement precision
If conventional testing methods are used during a pandemic, then specific virus identification can be attempted, but there is typically a lapse in development, production, and distribution of novel viral detection agents that allows for viral spread without epidemiologic data
Solution Approach 1:
The filter material is pre-impregnated with pathogen-binding adsorptive reagent before use, so that when breath condensate is collected, the binding reaction occurs immediately without requiring subsequent processing steps, reagent addition, or incubation periods that delay results in conventional methods
Solution Approach 2:
The patent skips the time-consuming intermediate steps of conventional testing including sample transport to laboratories, complex sample preparation, and sequential processing steps by performing the entire detection process in a single immediate step at the point of care
3Measurement precision
If conventional testing methods are used, then specific virus identification can be achieved, but asymptomatic carriers remain undetected and contribute to disease spread due to testing limitations including availability, cost, resource utilization, and time delay until test result
Solution Approach 1:
The filter material performs self-detection through an inherent color change mechanism when pathogen-binding reagent reacts with viral particles, eliminating the need for laboratory equipment, trained personnel, or complex analysis procedures, making the test accessible for widespread self-screening
Solution Approach 2:
The filter material is designed as a disposable, low-cost single-use component that can be mass-produced and distributed widely for asymptomatic screening programs, replacing expensive, resource-intensive conventional testing methods that cannot be scaled for population-level screening
4Ease of operation
If cursory screening is deployed such as screening questionnaires and fever testing, then some detection can be achieved, but this screening is low yield especially when considering asymptomatic carriers
Solution Approach 1:
The filter material incorporates a visual detection mechanism where pathogen-binding adsorptive reagent changes color when reacting with viral particles in breath condensate, providing an immediate visual result that is far more accurate than subjective fever assessment or questionnaire responses while remaining as simple to perform

AI summary
A rapid testing mechanism for respiratory viral pathogens includes a filter material positioned to capture exhaled breath particles from a respiratory tract. A portion of the filter material is impregnated with a pathogen binding adsorptive reagent. When the exhaled breath particles pass through the filter material the following occurs: when the binding adsorptive reagent reacts, a positive test for respiratory viral pathogens is indicated by the filter material; and when pathogen binding adsorptive reagent does not react, a negative test for respiratory viral pathogens is indicated by the filter material.
