Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If thermography is used to measure nose temperature without contact, then measurement non-intrusiveness is improved, but measurement continuity and ease of use deteriorate
Solution Approach 1:
The patent replaces contact-based mechanical temperature measurement with non-contact infrared temperature sensors that detect thermal radiation from the skin surface. This allows continuous temperature monitoring without physical contact, maintaining non-intrusiveness while enabling continuous measurement through automated sensor activation and data logging capabilities.
Solution Approach 2:
The temperature measurement system is designed to operate automatically without requiring user intervention. The sensors continuously monitor temperature, the microcontroller processes the data autonomously, and results are displayed or transmitted automatically. This self-service operation enables continuous measurement while maintaining non-intrusiveness as the system functions independently once activated.
2Measurement precision
If multiple temperature sensors are deployed on the face, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent divides the face into multiple measurement zones (nose, forehead, cheek, ear) and places temperature sensors at each zone. This segmentation allows simultaneous monitoring of different facial regions, improving overall measurement precision by capturing temperature variations across the face while managing complexity through modular sensor placement and independent measurement channels.
Solution Approach 2:
The patent employs a universal microcontroller unit that handles data acquisition, processing, and control for all temperature sensors. This single multi-functional component manages multiple sensors, reducing overall system complexity compared to having separate processing units for each sensor. The universal controller integrates multiple functions (sensing, processing, display, transmission) into one device.
