Pathogen Detection Apparatus Dynamic Re-testing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pathogen detection methods often result in false negatives due to sampling errors, particularly when collecting pathogens from a subject's breath.
Innovation Solution
A pathogen detection apparatus that includes a body temperature measurement device, a collector for pathogens, a detector for pathogen analysis, and a controller that initiates additional detection if the body temperature is elevated and the initial detection is negative.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If pathogen detection is performed only once regardless of subject condition, then the detection process is simple and quick, but false negatives occur due to sampling errors
Solution Approach 1:
The detection system dynamically adjusts the number of detection operations based on the subject's body temperature. When body temperature is elevated (indicating possible infection), the system performs multiple detection operations. When body temperature is normal, only a single detection is performed. This dynamic adaptation resolves the contradiction by making detection reliability conditional rather than fixed.
Solution Approach 2:
The system changes the detection parameter (number of detection operations) based on the body temperature parameter. By using body temperature as a conditional parameter, the system determines whether to perform one or multiple detections, thereby adjusting detection reliability according to the subject's physiological state without permanently increasing detection time for all subjects.
2Reliability
If multiple pathogen detection operations are performed for all subjects, then false negatives are reduced, but the detection process becomes more complex and time-consuming
Solution Approach 1:
The system performs a preliminary assessment of the subject's body temperature before determining the detection strategy. This preliminary action allows the system to prepare the appropriate number of detection operations in advance, reducing the perceived complexity during actual detection by having the protocol predetermined based on physiological indicators.
Solution Approach 2:
The detection process complexity is made dynamic rather than static. The system adapts the number of detection operations based on real-time body temperature measurements, performing multiple operations only when necessary (elevated temperature) and single operations when sufficient (normal temperature).
3Reliability
If additional detection is performed only when body temperature is elevated, then false negatives are reduced for high-risk subjects, but the system requires additional measurement capabilities
Solution Approach 1:
The detection system is designed with multi-functionality, combining both body temperature measurement and pathogen detection capabilities in a single integrated system. This universal design allows the system to perform multiple functions (temperature monitoring and pathogen detection) without requiring completely separate devices, thereby reducing overall system complexity while improving reliability for high-risk subjects.

AI summary
A pathogen detection apparatus includes an obtainer that measures a body temperature of a subject and outputs information indicating the body temperature, a collector that performs a pathogen collection operation for collecting a pathogen carried by the subject or a pathogen in air around the subject, a detector that performs a pathogen detection operation for detecting the pathogen collected by the collector, a notifier that provides a notification indicating a detection result obtained by the detector, and a controller. In a case where the body temperature output by the obtainer is higher than a predetermined threshold value and the detection result obtained by the detector is negative, the controller controls the detector to perform another pathogen detection operation for detecting a pathogen.
