Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If temperature sensing and hand sanitization features are integrated into the access control system, then user safety and sanitation are improved, but device complexity increases
Solution Approach 1:
The patent combines temperature sensing (IR transmitter and receiver), hand sanitization (UV-C LEDs), and access control functionalities into a single integrated device. This merging approach improves user safety by addressing multiple concerns (health screening and sanitation) while managing system complexity through unified design rather than separate standalone units.
Solution Approach 2:
The access control system is designed to perform multiple functions: temperature measurement, hand sanitization, and access control. This multi-functionality allows a single device to address various user safety and security needs, improving overall reliability without requiring multiple separate systems.
2Reliability
If multiple safety features (temperature sensing, hand sanitization) are added to the access control system, then the comprehensiveness of safety coverage is improved, but manufacturing cost increases
Solution Approach 1:
By integrating temperature sensing, hand sanitization, and access control into one device, the patent reduces the need for multiple separate systems, thereby managing manufacturing costs while providing comprehensive safety coverage.
Solution Approach 2:
The hand sanitization feature uses UV-C LEDs that automatically sanitize hands when placed in the palm area, providing self-service sanitation without requiring additional manual intervention or complex dispensing mechanisms, thus controlling manufacturing costs.
3Adaptability or versatility
If the system integrates multiple functions (access control, temperature sensing, hand sanitization), then the versatility of the system is improved, but device complexity increases
Solution Approach 1:
The system is designed to perform access control, temperature sensing, and hand sanitization functions within a single device, enhancing versatility by addressing multiple user needs simultaneously while managing complexity through integrated design.
Solution Approach 2:
The device is divided into distinct functional modules (IR transmitter, IR receiver, UV-C LEDs, access control components) that can be independently designed and maintained, allowing high versatility while managing complexity through modular architecture.

Data Source
AI summary
An access control system includes an identification unit having an infrared (IR) transmitter, an IR detector that receives reflected IR radiation from one or more body parts of the user, one or more signal processing components to determine a temperature of the user, a hand sanitization unit that sanitizes hands of the user when the hands are placed in a palm placement area, and an identification device to receive identification information of the user. The access control system also includes a processor that receives the reading of the user, instructs a door lock controller to unlock a door when the temperature is below the threshold temperature or the temperature is within the temperature range. The processor sends an alert when the temperature is above the threshold temperature or the temperature is outside the temperature range, and sends identification information of the user to one or more network devices.
