Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing visible light detectors in public places face challenges in dim conditions, fail to detect temperature, and have privacy concerns due to continuous operation, with inefficient record retrieval and high energy consumption.

A heat source detection system combining infrared and visible light detectors, where an infrared light detector identifies heat sources and activates a visible light detector only when specific conditions are met, reducing unnecessary power usage and privacy issues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If visible light detectors operate continuously for long-term monitoring, then detection coverage is improved, but energy consumption increases and privacy issues arise
Solution Approach 1:
The system uses infrared detectors for continuous periodic scanning to detect heat sources, while visible light detectors are activated only periodically when heat source anomalies are detected. This periodic activation pattern reduces energy consumption and privacy concerns while maintaining reliable detection coverage through the always-on infrared monitoring capability.
2Reliability
If visible light detectors operate continuously, then detection function is improved, but privacy issues occur
Solution Approach 1:
Visible light detectors are activated only periodically when infrared heat source detection identifies anomalies requiring visual confirmation. This periodic rather than continuous operation minimizes privacy intrusion while maintaining comprehensive detection function through the combination of always-on infrared monitoring and on-demand visible light verification.
Solution Approach 2:
The detection system is segmented into two functional layers: infrared heat source detection for continuous monitoring and visible light detection for selective detailed observation. This segmentation allows the system to maintain detection function while reducing privacy issues by limiting visible light activation to specific situations.
3Measurement precision
If visible light detectors are activated frequently, then detection accuracy is improved, but energy consumption increases
Solution Approach 1:
The system activates visible light detectors periodically only when infrared heat source detection identifies anomalies, rather than continuously or frequently. This selective periodic activation maintains detection accuracy for critical events while significantly reducing energy consumption compared to frequent or continuous visible light detection.
Solution Approach 2:
Infrared heat source detection serves as an intermediary screening mechanism that filters which situations require visible light detection. This intermediary layer ensures visible light detectors are activated only when necessary for accurate measurement, optimizing both detection accuracy and energy consumption.
