Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing monitoring systems require significant labor and cost to implement and may suffer from reduced security due to low detection accuracy when relying on a single sensor for target recognition.
Innovation Solution
A monitoring system utilizing at least one sensor, a monitoring camera with a microphone and image capturing unit, a master device connected to a fixed telephone network, and a mobile phone terminal for wireless communication, which records or outputs warnings based on detections from multiple sensors and cameras, improving security and reducing costs by leveraging existing infrastructure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single sensor is used for target recognition, then device complexity and cost are reduced, but monitoring accuracy and security deteriorate
Solution Approach 1:
The patent combines multiple sensors (human sensor, motion sensor, temperature sensor) and monitoring cameras to detect events. The master device integrates signals from these multiple sensors to determine whether an event has occurred, thereby improving monitoring accuracy while maintaining reasonable system complexity through centralized control.
Solution Approach 2:
The master device serves multiple functions: it receives detection signals from various sensors, determines event occurrence, controls monitoring cameras, and communicates with both fixed telephone networks and mobile phone terminals. This multi-functionality reduces the need for separate dedicated devices for each function.
2Reliability
If a dedicated monitoring system is introduced, then monitoring functionality is provided, but labor and implementation cost increase
Solution Approach 1:
The system utilizes existing infrastructure including fixed telephone networks and mobile phone terminals for communication purposes. The master device can communicate through both fixed telephone lines and mobile networks, allowing the system to leverage already-deployed communication infrastructure rather than requiring dedicated monitoring communication systems.
Solution Approach 2:
The system automatically determines event occurrence based on sensor signals and automatically controls monitoring cameras and notifications. The master device autonomously processes sensor data, decides when events have occurred, and triggers appropriate responses without requiring manual intervention or dedicated monitoring personnel.
3Measurement precision
If multiple sensors are used for event detection, then monitoring accuracy is improved, but device complexity increases
Solution Approach 1:
Multiple sensors detecting different parameters (human presence, motion, temperature) are combined in the master device. The master device integrates these diverse sensor signals to comprehensively determine event occurrence, improving detection accuracy by considering multiple indicators simultaneously rather than relying on a single sensor type.
Solution Approach 2:
The master device acts as an intermediary that receives and processes signals from multiple sensors. It centralizes the processing of detection signals, determines event occurrence based on combined sensor input, and controls the monitoring cameras. This intermediary role simplifies the overall system architecture by providing a single point of decision-making rather than requiring complex direct interactions between multiple sensors.

AI summary
A monitoring system includes at least one sensor, at least one monitoring camera, a master device that is connected to a fixed telephone network so as to perform calls to other fixed telephones, and a mobile phone terminal that is connected to other mobile phones via a mobile phone network. The master device records an image captured by the monitoring camera or outputs warning information depending on whether or not an event is detected by at least two of the sensors and the monitoring cameras.
