Pathogen Detection System Dynamic Mode Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current pathogen detection systems are inefficient as they continuously monitor for pathogens throughout the year, wasting resources and failing to accurately track infectious disease spread outside peak seasons, and consume excessive reagents due to frequent detections.
Innovation Solution
A pathogen detection system with multiple detectors and a controller that adjusts detection modes based on real-time pathogen concentration data, reducing detection frequency when concentrations are low and increasing it when necessary, thereby optimizing resource usage and reagent consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If pathogen detectors continuously monitor for pathogens throughout the year, then detection coverage is maintained, but resource consumption and reagent usage increase excessively
Solution Approach 1:
The system dynamically adjusts the detection mode of pathogen detectors based on real-time detection results from other detectors. When a pathogen is detected at one location, the system activates detectors in surrounding areas; when no pathogen is detected, detectors remain inactive or operate at reduced frequency, optimizing resource usage while maintaining detection coverage.
Solution Approach 2:
The controller receives detection results from pathogen detectors and uses this feedback to adjust the operating mode of other detectors. This feedback mechanism ensures that detection resources are allocated efficiently based on actual pathogen presence, reducing unnecessary reagent consumption while maintaining reliable detection coverage in areas where pathogens are likely to spread.
2Measurement precision
If pathogen detectors operate at high frequency, then detection accuracy improves, but reagent consumption increases
Solution Approach 1:
Instead of operating all detectors at high frequency continuously, the system applies partial action by activating detectors at high frequency only in areas where pathogens are detected or suspected. Other detectors operate at lower frequency or remain inactive, reducing overall reagent consumption while maintaining detection accuracy where needed.
Solution Approach 2:
The system changes the operational parameters of detectors dynamically based on detection results. Detection frequency, sampling volume, and reagent usage are adjusted as parameters according to the current epidemiological situation, allowing high detection accuracy when necessary while minimizing reagent consumption during low-risk periods.
3Reliability
If all pathogen detectors operate continuously, then comprehensive monitoring is achieved, but system efficiency decreases
Solution Approach 1:
The monitoring system is segmented into active and inactive detector groups based on real-time pathogen detection results. Instead of operating all detectors continuously, the system segments detector operations to match actual pathogen distribution patterns, improving overall system efficiency while maintaining comprehensive monitoring coverage through coordinated detector activation.

AI summary
A pathogen detection system includes pathogen detectors disposed in different locations, and a controller. The pathogen detectors include a first pathogen detector and a second pathogen detector. The first pathogen detector transmits a first detection result obtained as a result of pathogen detection to the controller, and the second pathogen detector transmits a second detection result obtained as a result of pathogen detection to the controller. In a case where the first detection result satisfies a predetermined condition, the controller causes the second pathogen detector to change a mode related to the pathogen detection from a first mode to a second mode.
