Multi-Sensor Indoor Risk Detection for Elderly Home Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Elderly individuals living alone face challenges in receiving timely assistance during risk situations due to difficulties in continuous monitoring, and existing sensor-based systems are inadequate for quick response to emergencies.
Innovation Solution
A management system using multiple sensors (passive infrared human body detection, temperature, humidity, fine dust, carbon dioxide, and smoke sensors) to continuously monitor indoor conditions, generating scores for discomfort, pollution, fire risk, and motion abnormalities, and transmitting alerts to guardians when thresholds are exceeded.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a home CCTV is installed for continuous monitoring of elderly persons living alone, then the guardian can monitor the situation continuously, but it is difficult for the guardian to continuously check the situation through CCTV, resulting in delayed response when risk situations occur
Solution Approach 1:
The monitoring system automatically detects risk situations and sends notifications to guardians without requiring continuous manual monitoring. The system serves itself by autonomously analyzing sensor data, determining risk levels, and triggering alerts, thereby resolving the contradiction between reliable detection and ease of operation.
Solution Approach 2:
The patent replaces the mechanical system of continuous human monitoring through CCTV with an automated sensor-based detection system. Multiple sensors (temperature, humidity, motion, smoke) automatically monitor the environment and substitute for the need for continuous human observation, improving both reliability and ease of operation.
2Measurement precision
If multiple sensors are used to comprehensively determine risk situations, then the detection accuracy and response speed improve, but the device complexity increases
Solution Approach 1:
The patent segments the monitoring system into multiple independent sensor modules (temperature sensor, humidity sensor, motion detection sensor, smoke sensor) that each perform specific detection functions. This segmentation allows for high measurement precision through specialized sensors while managing device complexity through modular design and clear functional separation.
Solution Approach 2:
The management system apparatus integrates multiple sensor types into a single unified system that performs comprehensive risk assessment. The system universally processes data from various sensors through a common determination algorithm, achieving high measurement precision across multiple parameters while avoiding the complexity of separate independent systems.
