Hand Hygiene Notification Apparatus with Actuation Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In high-infection-risk environments, such as hospitals and public transport, individuals often forget to use hand cleansing devices, posing a risk of germ transmission due to lack of reminders and monitoring systems for effective hand hygiene.
Innovation Solution
A notification apparatus that detects hand cleansing device actuation and exit events, providing alerts and notifications to individuals and others if hands are not properly cleansed, using sensors and a controller to ensure a minimum safe cleansing time is met, with visible, audible, or haptic feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If hand cleansing devices are provided in high-infection-risk environments, then hygiene standards should be maintained, but individuals often forget to use them, posing a risk of germ transmission
Solution Approach 1:
The system provides real-time feedback to individuals through notifications when they approach a hand cleansing device, when they exit without using it, or when they fail to complete the required cleansing duration. This feedback mechanism directly addresses the problem of individuals forgetting to use the device by providing timely reminders and alerts.
Solution Approach 2:
The system performs preliminary actions by detecting when an individual approaches the hand cleansing device and sending a notification beforehand to remind them to use it. This prevents the forgetting issue by initiating the reminder action before the individual actually needs to cleanse their hands.
2Reliability
If monitoring systems are implemented to track hand cleansing usage, then infection risk is reduced, but system complexity and cost increase
Solution Approach 1:
The hand cleansing device monitors its own usage through integrated sensors that detect when the device is activated and automatically track the cleansing duration. The system self-evaluates whether the required minimum cleansing time was met and autonomously generates appropriate notifications without requiring complex external monitoring infrastructure.
Solution Approach 2:
The notification system serves multiple functions: it reminds users to cleanse hands, alerts them when they exit without using the device, notifies them when they fail to meet the minimum cleansing duration, and can alert others in the environment. This multi-functionality achieves comprehensive infection prevention with a single integrated system.
3Productivity
If notifications are provided to remind individuals to cleanse hands, then hand hygiene effectiveness is improved, but energy consumption increases
Solution Approach 1:
The notification system operates periodically by triggering notifications only at specific events such as when an individual approaches the device, when they exit the monitored area, or when the cleansing duration is insufficient. This periodic activation pattern maintains high hand hygiene effectiveness while minimizing continuous energy consumption compared to constant monitoring and notification systems.

AI summary
A notification apparatus is provided for monitoring actuation of a hand cleansing device. The apparatus comprises: a hand cleansing device actuation sensor arranged to detect an actuation of a hand cleansing device by an individual, and further arranged to output an actuation signal following said actuation; a controller arranged to receive the actuation signal and output a control signal according to the actuation signal; and a notification member arranged to receive the control signal and output a notification to the individual based on the control signal. The apparatus of the present invention aims to provide a simple and cost- effective solution to ensuring hygiene requirements are upheld while minimising form factor and skill required for installation.
