Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing security systems are inefficient in timely and effective denial of access to individuals who may pose health risks, especially in large facilities where manual health assessments are impractical during epidemics or pandemics.
Innovation Solution
A method and apparatus that utilize a thermal sensor to estimate a person's body surface temperature and prompt them with verification questions through a user interface, determining whether their responses and temperature match criteria for granting entry, thereby automating the access control process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual health assessments are implemented at checkpoints, then security and health monitoring are improved, but efficiency and speed of entry are reduced
Solution Approach 1:
The patent replaces manual health assessment with an automated system using thermal sensors to detect body temperature and a machine learning model to evaluate health status. This substitution of mechanical/manual processes with automated technological systems resolves the contradiction by maintaining reliable health monitoring while dramatically improving entry speed and efficiency.
Solution Approach 2:
The system enables self-service health assessment where individuals are automatically evaluated as they approach the checkpoint without requiring manual intervention. The thermal sensor and machine learning model work autonomously to determine health status, allowing rapid processing while maintaining assessment reliability.
2Productivity
If automated thermal sensing is implemented, then entry speed is improved, but measurement accuracy may be reduced
Solution Approach 1:
The system incorporates feedback mechanisms where the machine learning model continuously refines temperature measurements and health assessments based on thermal sensor data. The automated evaluation process uses feedback loops to improve measurement accuracy while maintaining high entry speed, resolving the contradiction between automation and precision.

AI summary
Disclosed herein are apparatuses and methods for granting entry through a checkpoint. The implementations include receiving a request for entry of a person through a checkpoint. The implementations include estimating, via a thermal sensor, a body surface temperature of the person, and generating, via a user interface, a notification that prompts the person to answer at least one verification question. The implementations include receiving, via the user interface, at least one user response to the at least one verification question. The implementations include determining whether the at least one user response and the body surface temperature match criteria for gaining entry through the checkpoint. Additionally, the implementations include granting the request for entry in response to determining that the at least one user response and the body surface temperature match the criteria.
