Electronic Notification System for Passive Status Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing personal emergency response systems are inflexible, difficult to use, and prone to malfunctions, as they rely on specific sensors or pushbutton transmitters that require careful installation and constant carrying, limiting their effectiveness in monitoring individuals living alone.
Innovation Solution
A method that categorizes and weights information from various sources, such as consumption, sensor data, and interaction with devices, to provide a reliable and flexible electronic notification system, allowing for continuous evaluation of a person's status without the need for continuous data handling, using a score system to indicate potential health issues or emergencies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a specific sensor or pushbutton transmitter is used for emergency monitoring, then the system can detect emergencies, but the system becomes inflexible and difficult to use
Solution Approach 1:
The system automatically monitors multiple parameters (movement, consumption, interactions) without requiring the user to actively engage with the device. The monitoring occurs passively through existing sensors and data sources, eliminating the need for users to carry or operate specialized equipment while maintaining reliable emergency detection
Solution Approach 2:
The system uses a multi-functional approach by integrating various existing sensors and data sources (movement sensors, consumption data from smart meters, interaction data from devices) into a single monitoring framework. This allows the system to detect multiple types of emergencies through different parameters without requiring separate specialized devices
2Reliability
If a specific sensor system is installed for monitoring, then emergency detection is possible, but the installation and maintenance become complex
Solution Approach 1:
The system merges multiple existing data sources and sensors into a single integrated monitoring system. Instead of installing separate specialized sensors, the system combines data from movement sensors, consumption data from existing smart meters, and interaction data from various devices, reducing installation complexity while maintaining detection capability
Solution Approach 2:
The system introduces a central evaluation unit that acts as an intermediary, collecting and processing data from multiple existing sources. This mediator approach allows the system to utilize existing infrastructure without requiring complex direct connections between all components, simplifying installation and maintenance
3Measurement precision
If multiple information sources are integrated for status assessment, then the accuracy and reliability of status determination improves, but the system complexity increases
Solution Approach 1:
The system uses feedback mechanisms by continuously evaluating multiple parameters (movement, consumption, interactions) and comparing them against expected patterns. The evaluation unit processes feedback from all sources to dynamically adjust the status assessment, improving accuracy through multi-parameter correlation while managing complexity through systematic feedback processing

AI summary
The invention relates to a Method for sending an electronic notification to a recipient, the notification relating to an assumed status of a person living in a household, wherein the method comprises generating and/or selecting the notification based on actual information referring to a plurality of different categories relating to at least a predetermined time interval, wherein, within the time interval an actual value of the information is compared with a nominal value of the information, the difference between the actual value of the information and the nominal value of the information is weighted to obtain weighted actual information, and the weighted information of the actual information of the plurality of different categories is put into relation to obtain the assumed status of the person or the household, wherein the categories are selected from the following group: information about consumption of at least power, water and/or gas in the household, a value of at least one sensor located in the household and/or carried by the person, information about health data of the person, information obtained by at least a smart device located in the household and information about interaction of the person with regard to an interactive device.
