Microbe Scanning Device for Hand Hygiene Enforcement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current solutions for enforcing hand hygiene in public areas, such as hand sanitizers, are ineffective in regulating and monitoring individuals to ensure proper hand sanitation, leading to potential increases in germ and bacteria transmission in high-interaction environments like medical facilities and food service industries.
Innovation Solution
A microbe scanning device that scans users' hands for microbial presence, generates notifications, and communicates wirelessly to enforce hand hygiene by restricting access to certain areas or resources based on sanitation status, using a network-connected system with sensors and output devices for real-time feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If hand sanitizers are provided in public areas, then hand hygiene is promoted, but monitoring and enforcement capability is lacking
Solution Approach 1:
The system implements real-time feedback by scanning hands with sensors, detecting microbial presence, and providing immediate notifications to users and authorities. This closed-loop feedback mechanism transforms the open-hand sanitizer approach into a monitored enforcement system that tracks sanitation status and communicates results through multiple channels including visual displays and wireless communications.
Solution Approach 2:
The patent introduces an intermediary monitoring system between hand sanitizer usage and public health safety. This intermediary layer includes sensors, processors, and notification devices that mediate the connection between individual hand hygiene actions and overall public health monitoring, enabling enforcement capabilities without directly interfering with the hand sanitizer function.
2Measurement precision
If microbial scanning is implemented, then sanitation monitoring is improved, but device complexity increases
Solution Approach 1:
The system achieves multi-functionality by integrating multiple capabilities into a single device: hand scanning, microbial detection, user identification, real-time notification, and data logging. This universal approach consolidates what would otherwise require separate systems into one integrated platform, managing complexity through functional integration rather than proliferation of separate components.
Solution Approach 2:
The scanning system performs self-service functions by automatically detecting microbes, processing scan data, generating notifications, and communicating results without requiring manual intervention. The system autonomously executes the entire monitoring workflow from scanning to enforcement notification, reducing operational complexity despite the advanced detection capabilities.
3Reliability
If real-time feedback is provided, then hand hygiene enforcement is improved, but time for user interaction increases
Solution Approach 1:
The system performs preliminary actions by pre-positioning sensors and notification devices in strategic locations before users arrive. Hand sanitizers are pre-placed, scanning zones are pre-configured, and notification systems are pre-activated, enabling immediate enforcement upon user arrival without setup or preparation time, thus minimizing interaction delay while maintaining reliable enforcement.
Data Source
AI summary
A microbe scanning device and methods are disclosed. The device includes a housing that includes a sensor(s), output device(s) that conveys text/audio/images, and control circuit(s) coupled to the sensor(s) and output device(s). the sensor captures first ASD and second ASD. The first and second ASD each includes an image of an appendage captured using one or more of radio waves, visible light (“VL”), and infrared light (“IR”). The control circuit is configured to determine, using ASD, whether a user is present; determine, using ASD, whether hands are present when the user is present; determine, using ASD, whether microbiol material is present on the hands; generate a notification when the microbial material is present on the hands; transmit, via the output device, the notification; generate a notification when the microbial material is not present on the hands; and transmit the second notification when generated.
