Self-Propelled Pathogen Detection Using Traffic Line Targeting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air purifiers, both stationary and self-propelled, are inefficient in deactivating infectious viruses like influenza in crowded facilities such as care facilities, hospitals, and cram schools, as they do not consider human behavior patterns or traffic lines, leading to potential mass infections if the virus is not deactivated promptly.
Innovation Solution
A self-propelled pathogen detection device that uses traffic line information to identify high-probability pathogen presence regions, equipped with a detection part, movement mechanism, position acquisition part, and control part to move and detect pathogens, and a cleaning part to deactivate them using a hypochlorous acid aqueous solution, adjusting treatment based on pathogen concentration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional air purifiers are used in crowded facilities, then they can provide general air purification, but they are inefficient in deactivating infectious viruses because they do not consider human behavior patterns or traffic lines
Solution Approach 1:
The system performs preliminary actions by acquiring traffic line information in advance and pre-determining target regions where pathogens are likely to exist before actual pathogen detection begins. This allows the air purifier to proactively position itself in high-risk areas rather than reactively responding to detected pathogens, thereby improving deactivation efficiency while maintaining manageable system complexity through structured data collection.
Solution Approach 2:
The system dynamically adjusts the target region based on acquired traffic line information, allowing the air purifier to adapt its detection and deactivation focus to changing human movement patterns. This dynamic adaptation enables the system to continuously optimize pathogen deactivation efficiency in response to varying facility usage patterns without requiring complete system redesign.
2Loss of time
If the air purifier targets all regions equally, then comprehensive coverage is achieved, but early detection in high-risk areas is delayed
Solution Approach 1:
The system applies local quality by determining specific target regions within the facility based on traffic line information, concentrating detection resources in areas where pathogens are most likely to exist. Instead of uniform detection across all spaces, the air purifier focuses on high-traffic or high-risk zones, achieving earlier detection in critical areas while maintaining overall system effectiveness.
3Productivity
If the air purifier moves to follow traffic lines, then it can detect pathogens early in high-probability regions, but it requires self-propulsion and autonomous navigation capabilities
Solution Approach 1:
The air purifier implements self-service by autonomously navigating to determined target regions using its self-propulsion capability. The device independently acquires traffic line information, determines optimal detection locations, and moves itself to those positions without external intervention, thereby achieving early pathogen detection in high-risk areas while managing automation through self-directed operation.
