Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If infrared temperature screening is used for fever detection, then temperature measurement can be obtained, but the measurement consistency deteriorates and requires verification
Solution Approach 1:
The patent introduces an intermediary verification process where a second infrared camera or temperature measurement device is used to verify initial temperature readings. This intermediary step resolves the contradiction by providing a mechanism to confirm inconsistent measurements without requiring direct physical contact, thereby maintaining measurement consistency while improving screening reliability.
Solution Approach 2:
The patent replaces the mechanical contact-based verification method with a non-contact infrared verification system. Instead of physically contacting the individual for verification (which would require mechanical interaction), a second infrared camera performs contactless verification, substituting the mechanical verification system with an optical/infrared-based system that maintains measurement consistency while improving reliability.
2Object-affected harmful factors
If contactless temperature screening is implemented, then viral spread is prevented, but measurement verification becomes more difficult
Solution Approach 1:
The patent introduces a multi-camera infrared system as an intermediary verification mechanism. Instead of requiring physical contact for verification, a second infrared camera acts as an intermediary device to independently measure and verify temperature readings, maintaining contactless operation while reducing verification difficulty through redundant non-contact measurement.
Solution Approach 2:
The patent implements a feedback mechanism where temperature measurements from multiple infrared cameras are compared and cross-validated. The system provides real-time feedback by analyzing discrepancies between measurements and automatically triggering re-measurement or alert protocols, making verification easier while maintaining contactless operation and preventing viral spread.
3Measurement precision
If multiple temperature sensors are deployed for verification, then measurement accuracy improves, but device complexity increases
Solution Approach 1:
The patent combines multiple infrared temperature sensors and cameras into an integrated sensor assembly with shared processing electronics and unified control logic. This merging approach maintains measurement accuracy through multi-sensor verification while reducing overall device complexity by consolidating power management, data processing, and communication interfaces into a single coordinated system rather than separate independent devices.
