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 simple and effective, but the risk of spreading infectious diseases increases
Solution Approach 1:
The patent replaces mechanical contact-based temperature measurement (thermometers requiring physical contact) with optical sensing systems that detect body temperature through emitted infrared radiation. This substitution eliminates the need for physical contact between the screening device and the person being screened, thereby maintaining screening effectiveness while removing the transmission risk associated with contact methods.
Solution Approach 2:
The patent introduces infrared radiation as an intermediary medium that carries temperature information from the human body to the sensing device without requiring direct contact. The optical sensor detects the infrared emissions naturally given off by the body, using this electromagnetic radiation as a mediator to transfer thermal information across a non-contact interface, thus breaking the chain of potential contamination.
2Object-affected harmful factors
If touchless sensors are used for temperature detection, then the spread of infectious diseases is reduced, but the device complexity increases
Solution Approach 1:
The patent designs the screening system to perform multiple functions through an integrated platform: optical temperature detection, health criteria evaluation, message delivery via output interface, and coordination through control circuitry. By combining these functions into a single multi-functional device, the system avoids the complexity that would arise from coordinating multiple separate devices, making the touchless approach practical and manageable.
Solution Approach 2:
The patent merges the temperature sensing function, health assessment logic, and communication capabilities into a unified screening system. The control circuit integrates inputs from optical sensors and processes health criteria determination, while the output interface consolidates message delivery. This merging reduces operational complexity by having a single system coordinate all touchless screening activities rather than requiring separate systems for each function.
3Device complexity
If traditional contact-based temperature screening is used, then the equipment is simple, but human contact is required which increases disease transmission risk
Solution Approach 1:
The patent replaces simple mechanical contact thermometers with optical sensing technology that detects body temperature through infrared radiation. While this increases device complexity compared to basic contact thermometers, it eliminates the harmful contact-based transmission route. The optical system uses non-contact infrared detection to measure temperature, substituting mechanical contact with electromagnetic field-based measurement.
Solution Approach 2:
The patent uses infrared radiation as an intermediary to transfer temperature information without physical contact. The optical sensor detects the natural infrared emissions from the human body, using this electromagnetic radiation as a mediator that allows temperature measurement while maintaining physical separation between the screening device and the person being screened, thereby preventing disease transmission.
