Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a pressing need for accurate and rapid detection of Avian Flu to provide early warning of a pandemic and contain the spread of the disease, as existing methods are inadequate for rapid identification and surveillance.
Innovation Solution
A system comprising a fluidic device with a sample collection unit and an assay assembly that detects analytes indicative of influenza viral infections, such as surface glycoproteins like hemagglutinin and neuraminidase, in bodily fluids from humans, poultry, and wild birds, using immunoassay reagents and a communication assembly for real-time signal transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If traditional influenza detection methods are used, then detection accuracy can be maintained, but detection speed is too slow for rapid pandemic response
Solution Approach 1:
The system divides the detection process into separate functional modules: a fluidic device for sample processing and immunoassay, a reader assembly for signal detection, and a communication assembly for data transmission. This segmentation allows each module to be optimized independently, enabling rapid detection while maintaining accuracy through specialized components.
Solution Approach 2:
The patent replaces traditional mechanical and manual detection methods with an automated immunoassay system that uses chemical reactions (antigen-antibody binding) and optical/electronic signal detection. This substitution eliminates manual intervention, accelerates the detection process, and maintains precision through standardized assay protocols and automated reading.
2Adaptability or versatility
If comprehensive surveillance of multiple influenza strains is implemented, then detection coverage is improved, but system complexity increases
Solution Approach 1:
The fluidic device and immunoassay system are designed with universal components that can detect multiple influenza strains (A, B, and C) and various hemagglutinin types (H1-H16) and neuraminidase types (N1-N5). The same basic device architecture and detection methodology are used across all assays, allowing the system to handle multiple targets without proportionally increasing complexity.
Solution Approach 2:
The system achieves versatility by changing the biochemical parameters of the assay (different antibodies, antigens, and reaction conditions) rather than changing the physical structure of the device. This allows a single device platform to detect multiple influenza strains by simply changing the immunoassay reagents and detection parameters.
3Loss of time
If real-time data transmission and warning systems are implemented, then pandemic response time is reduced, but infrastructure requirements increase
Solution Approach 1:
The communication assembly acts as an intermediary between the detection system and external surveillance networks. It receives detected signals from the reader assembly and automatically transmits them to external devices or databases, enabling real-time warning systems without requiring complex manual reporting infrastructure. This intermediary component simplifies the connection to broader surveillance systems.
4Productivity
If automated immunoassay systems are used, then detection speed and accuracy are improved, but device complexity increases
Solution Approach 1:
The patent combines multiple functions (sample processing, immunoassay reaction, signal detection, and data communication) into an integrated system where components work together seamlessly. The fluidic device merges sample preparation and assay execution, while the reader assembly combines signal detection and data processing. This merging improves productivity by eliminating manual transfer steps between separate devices while managing complexity through functional integration.
