Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional temperature measurement systems are used in harsh environments, then device simplicity is maintained, but measurement precision deteriorates due to environmental interference
Solution Approach 1:
A reference device is introduced as an intermediary element between the thermal camera and the harsh environment. This reference device provides a known reference temperature that the thermal camera uses to compensate for environmental interference, thereby improving measurement precision without requiring the camera itself to be complex or protected against all environmental factors
Solution Approach 2:
The system implements feedback by continuously monitoring the reference temperature from the reference device and using this information to adjust and compensate for environmental effects on temperature measurements. This feedback mechanism enables the system to maintain high measurement precision in harsh environments through real-time calibration
2Reliability
If conventional temperature measurement systems are used outdoors, then ease of operation is maintained, but reliability deteriorates due to exposure to harsh conditions
Solution Approach 1:
The reference device serves as a mediator that absorbs the impact of harsh environmental conditions, allowing the main thermal camera system to remain simple and easy to operate while the reference device handles the complexity of environmental compensation
Solution Approach 2:
The reference device autonomously maintains its reference temperature and automatically compensates for environmental effects without requiring manual intervention or complex operational procedures, thereby maintaining ease of operation while improving reliability
3Measurement precision
If conventional temperature measurement systems are used for fever detection, then device simplicity is maintained, but measurement precision deteriorates due to limited temperature range
Solution Approach 1:
The reference device acts as a mediator that provides a stable reference point across a wide temperature range, enabling the thermal camera to accurately detect fever temperatures even when the overall environmental temperature varies significantly, thereby improving fever detection precision without expanding the camera's inherent temperature range capability
