Solution Overview

Problem

Conventional detectors and sensors in public facilities and buildings are not cost-effective and fail to provide detailed data for high-level analysis or detection of multiple events, leading to insufficient surveillance and control, especially in emergency situations like smoke or carbon monoxide incidents, and they consume excessive power and violate personal privacy.

Innovation Solution

A device integrating a CO gas sensor, smoke sensor, and thermal imaging sensor that activates only upon detecting anomalies, capturing thermal images and creating a thermal map to identify persons and emergency sources, which is then transmitted to a server for geolocation and real-time communication to rescue personnel, using a rechargeable battery for independent power and a robust shell for 'black box' functionality.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If conventional detectors and sensors are installed in public facilities and buildings, then safety monitoring is provided, but detailed data for high-level analysis and multiple event detection cannot be obtained

Engineering Contradiction:
Improvedetection detailVSAvoidnumber of devices
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent combines multiple detection functions (thermal imaging, smoke detection, CO detection, motion detection) into a single integrated device. The thermal imaging sensor captures detailed thermal data, while smoke and CO sensors detect hazardous gases. This merging allows the system to obtain detailed data for high-level analysis and detect multiple event types simultaneously without requiring multiple separate devices, thus improving measurement precision while managing device complexity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The integrated detection device performs multiple functions: thermal imaging for person detection and localization, smoke detection for fire hazards, CO detection for carbon monoxide hazards, and motion detection for occupancy monitoring. This multi-functionality enables a single device to provide comprehensive safety monitoring and detailed data analysis across various emergency scenarios, replacing the need for multiple specialized devices.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Reliability

If multiple conventional detectors and sensors are installed to provide integral monitoring, then coverage is improved, but cost increases exponentially

Engineering Contradiction:
Improvemonitoring coverageVSAvoidinstallation cost
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

By merging multiple detection functions into a single integrated device, the patent reduces the total number of devices required for comprehensive monitoring. Instead of installing separate thermal cameras, smoke detectors, CO detectors, and motion sensors throughout a facility, a single multi-functional device provides equivalent or superior coverage, significantly reducing installation costs while maintaining or improving reliability.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The universal detection device performs multiple safety functions simultaneously, allowing one device to replace several specialized devices. This multi-functionality reduces the overall system cost while maintaining comprehensive monitoring coverage, as the integrated device eliminates the need for multiple device installations, wiring, and maintenance.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Loss of information

If conventional passive infrared motion detectors are used, then presence detection is provided, but detailed information about persons in emergency situations cannot be obtained

Engineering Contradiction:
Improveperson detection detailVSAvoidthermal detection capability
Core Design Contradiction:
Loss of informationVSMeasurement precision

Solution Approach 1:

The patent replaces conventional passive infrared (PIR) motion detectors with thermal imaging sensors. PIR detectors use pyroelectric cells to detect thermal changes in specific areas, providing only presence/absence information. Thermal imaging sensors capture detailed thermal images, enabling visualization of persons, identification of their locations, and assessment of their states (e.g., unconscious, moving). This substitution transforms limited mechanical detection into comprehensive thermal imaging, eliminating information loss while maintaining detection precision.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
