Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional temperature checks and clinical examinations are used for disease detection, then the method is simple to implement, but the diagnostic confidence level remains low
Solution Approach 1:
The patent combines multiple sensing modalities (thermal imaging, radar, visible light cameras) into a single integrated detection system. This merging of different measurement techniques allows the system to gather comprehensive physiological data (temperature, breathing rate, heart rate) simultaneously, thereby提高 diagnostic confidence while managing system complexity through unified processing.
Solution Approach 2:
The detection system is designed to perform multiple diagnostic functions using a single integrated platform. The same sensor array can detect fever, measure respiratory rate, monitor cardiac activity, and identify facial features for contactless interaction, eliminating the need for separate devices for each measurement and improving overall diagnostic reliability.
2Object-affected harmful factors
If contactless detection methods are used, then the risk of contamination is reduced, but the measurement precision may be affected
Solution Approach 1:
The patent replaces direct physical contact measurements with non-contact sensing technologies. Thermal cameras measure body temperature from a distance, radar sensors detect breathing and heart rates through electromagnetic waves, and visible light cameras capture facial features. This substitution eliminates contamination risk while maintaining measurement precision through advanced signal processing algorithms.
Solution Approach 2:
The system uses electromagnetic radiation (infrared for thermal imaging, microwave for radar) as an intermediary to obtain physiological measurements without direct contact. These intermediaries carry information about the patient's vital signs from a safe distance, enabling accurate measurement while preventing contamination between examiner and examinee.
3Productivity
If rapid diagnosis is implemented through automated processing, then the diagnostic speed increases, but the system complexity increases
Solution Approach 1:
The detection system incorporates automated processing algorithms that independently analyze the collected sensor data and generate diagnostic results without requiring manual interpretation. The system self-calibrates, automatically identifies vital signs from raw signals, and produces diagnostic confidence scores, thereby increasing diagnostic speed while managing complexity through automation.
Solution Approach 2:
The system implements real-time feedback loops where the processed diagnostic results are immediately displayed to guide subsequent actions. The automated processing continuously monitors incoming sensor data, adjusts analysis parameters based on detected patterns, and provides immediate diagnostic feedback, enabling rapid diagnosis while managing complexity through adaptive algorithms.
4Reliability
If multiple sensors are integrated for comprehensive measurements, then the diagnostic accuracy improves, but the device portability decreases
Solution Approach 1:
The patent employs thin-film sensor technologies and lightweight optical components to reduce the overall system weight. The thermal camera, radar sensor, and visible light camera are integrated into a compact, lightweight housing that maintains diagnostic accuracy while improving portability for mobile deployment scenarios.
