Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Accurately tracking occupancy limits and wait times in public spaces is challenging, leading to errors and potential safety and health risks, particularly evident during emergencies and pandemics like COVID-19.
Innovation Solution
A system comprising ultrasonic sensors, microcontrollers, and a display that calculates and transmits occupancy rates and wait times in real-time to electronic devices via a server, allowing for accurate monitoring and reporting of maximum capacity and estimated wait times for entry into a space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual tracking of occupancy limits is used, then device complexity is reduced, but measurement precision and reliability deteriorate due to multiple opportunities for error
Solution Approach 1:
The patent replaces manual mechanical counting methods with an automated sensor-based detection system. Ultrasonic sensors automatically detect and count occupants entering and exiting spaces, eliminating human error in manual tracking while providing precise, real-time occupancy data through electronic processing and display.
2Reliability
If real-time occupancy tracking is implemented, then reliability and safety are improved, but device complexity and cost increase
Solution Approach 1:
The patent divides the monitoring system into modular functional components: ultrasonic sensors for detection, microcontrollers for data processing, display units for visualization, and wireless communication modules for data transmission. This segmentation allows each component to perform its specific function independently, improving overall reliability while making the system easier to install, maintain, and scale.
3Loss of information
If wait time tracking is added to occupancy monitoring, then information completeness is improved, but device complexity increases
Solution Approach 1:
The patent designs the sensor system to perform multiple functions: the same ultrasonic sensors that detect occupancy also track wait times by monitoring the duration occupants remain in queue areas. This multi-functionality eliminates the need for separate tracking systems, reducing overall complexity while providing comprehensive information about both occupancy levels and wait times.
