Monitoring System Using Radio Transmitter Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current monitoring systems for older adults in their homes lack reliable methods to evaluate movement data from motion detectors and cannot clearly distinguish between the monitored person's movements and those of others, leading to difficulties in detecting emergencies and privacy concerns due to the use of cameras.
Innovation Solution
A monitoring system utilizing passive infrared sensors and radio transmitters/receivers, where passive infrared sensors detect movements and transmit data to a monitoring center, and radio transmitters carried by the person emit signals to identify them, allowing for clear identification of the monitored person's movements and reducing privacy concerns by not capturing images.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cameras are used to monitor the entire apartment, then the ability to detect emergencies and behavior patterns is improved, but privacy is compromised and user acceptance decreases
Solution Approach 1:
The patent extracts the essential monitoring function from camera-based visual surveillance and implements it through motion detectors that sense physical movement without capturing images. This removes the privacy-invasive element (visual recording) while preserving the core functionality (detecting movement patterns and emergencies).
Solution Approach 2:
The patent replaces the optical/mechanical camera system with an electronic sensing system using motion detectors. Instead of capturing visual information through lenses and sensors, the system uses motion detection technology to sense changes in the environment, substituting a less intrusive technological approach for the same monitoring purpose.
2Object-affected harmful factors
If motion detectors are used instead of cameras, then privacy is preserved, but the ability to reliably evaluate movements and identify the monitored person is reduced
Solution Approach 1:
The patent implements feedback mechanisms where motion detector data is continuously collected, analyzed, and used to refine the monitoring system's ability to distinguish between different persons and evaluate movement patterns. The system learns from accumulated data to improve its reliability over time, compensating for the initial limitations of motion detector technology.
Solution Approach 2:
The patent makes the motion detectors multi-functional by enabling them to perform both basic motion detection and person-specific pattern recognition. The same device that detects movement also collects data about movement patterns, duration, and location, which can be analyzed to identify the monitored person and evaluate their behavior, thus serving multiple purposes with a single technology.
3Device complexity
If motion detectors are used without person identification, then system complexity is reduced, but the ability to distinguish between the monitored person and others is lost
Solution Approach 1:
The patent applies preliminary action by pre-configuring the monitoring system with the specific movement patterns and characteristics of the person to be monitored before actual monitoring begins. This allows the system to establish a baseline for comparison, enabling it to distinguish the monitored person from others without requiring complex real-time identification technology.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system provides a reliable method for detecting emergencies and accurately attributing movement patterns to the monitored individual, minimizing false alarms and respecting privacy by not recording images, thus enabling effective monitoring without surveillance cameras.
Implementation Method 1
a motion detector provided in the apartment for detecting movement of the person in the apartment
Implementation Method 2
a radio transmitter carried by the person and a monitoring center, the geometric detection area of the motion detector being assigned to a predetermined geometric area of the apartment, the radio transmitter emitting a radio signal for identifying the person
