Dispenser with contaminant sensor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for detecting contaminants in facilities, such as hospitals and healthcare premises, are inadequate and fail to provide timely warnings of dangerous contaminant levels, often resulting in negative impacts on patients after symptoms appear.
Innovation Solution
A contaminant sensing dispenser system that includes sensors capable of detecting contaminants in dispensers for hand cleaning fluids or paper towels, generating signals, and comparing these signals to thresholds to provide early warnings, with a network of dispensers communicating data to a central processor for monitoring and alerting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional contaminant detection methods are used, then detection capability is provided, but timely warning of dangerous contaminant levels is not achieved
Solution Approach 1:
The sensor is positioned to detect contaminants before they reach dangerous levels that would affect patients. The system performs preliminary detection and provides advance warning, allowing preventive action to be taken before contamination becomes harmful.
Solution Approach 2:
The system continuously monitors contaminant levels and provides real-time feedback through alerts and notifications. This feedback mechanism enables timely response to changing contaminant conditions, ensuring dangerous situations are detected and addressed immediately.
2Reliability
If a network of dispensers with sensors is deployed, then monitoring coverage is improved, but device complexity increases
Solution Approach 1:
The dispenser units serve multiple functions: they dispense cleaning fluids to users and simultaneously function as sensor nodes in the monitoring network. This multi-functionality reduces the need for separate dedicated sensor devices, simplifying the overall system architecture while maintaining comprehensive coverage.
Solution Approach 2:
The contaminant sensing capability is merged with the existing dispenser infrastructure. By integrating sensors into dispensers that are already distributed throughout the facility, the system achieves wide monitoring coverage without requiring a separate network of dedicated detection devices.
