Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If direct or indirect physical contact is used for health screening, then the screening process can be performed with simple equipment, but it leads to the spread of infectious diseases
Solution Approach 1:
The patent replaces mechanical contact-based temperature measurement (thermometers requiring physical contact with body) with a non-contact infrared sensing system. The sensor detects thermal radiation from the body to determine temperature, eliminating the need for physical contact while maintaining measurement functionality. This resolves the contradiction by substituting the mechanical contact system with an optical/thermal field-based system.
Solution Approach 2:
The patent introduces an infrared sensor as an intermediary between the measurement objective and the system. The sensor acts as a mediator that captures thermal information from a distance without requiring direct contact, thus preventing disease transmission while enabling temperature screening. The intermediary device bridges the gap between contactless operation and effective measurement.
2Measurement precision
If manual health screening by designated employees is performed, then health questions can be individually assessed, but it reduces screening efficiency and increases time consumption
Solution Approach 1:
The patent implements a self-service screening system where individuals independently respond to health questions and undergo temperature screening without requiring a designated employee for each interaction. The system automatically processes responses, evaluates health criteria, and provides results, enabling mass screening while maintaining assessment accuracy through standardized protocols.
Solution Approach 2:
The system performs preliminary health assessment through automated questionnaires and pre-screening protocols before final temperature measurement. This structured preliminary action ensures comprehensive health evaluation while streamlining the process, allowing efficient batch processing of multiple individuals without sacrificing assessment thoroughness.
3Reliability
If multiple sensors and processing circuits are used for touchless screening, then disease transmission is prevented, but the device complexity increases
Solution Approach 1:
The patent combines multiple sensing functions (infrared temperature detection, visible light imaging, and proximity sensing) into a single integrated sensor module. The control circuit consolidates data processing from all sensors and coordinates the display output, merging multiple discrete components into a unified system that maintains contactless operation while reducing overall complexity.
Solution Approach 2:
The sensor system is designed with multi-functionality, where a single sensor array serves multiple purposes: temperature measurement, facial recognition, and presence detection. This universal approach allows the system to perform various screening functions without requiring separate dedicated sensors for each function, thereby reducing device complexity while maintaining reliable contactless operation.
