Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If handheld wireless devices are used to measure forehead temperature, then temperature measurement can be performed, but severe delays occur and human movement is disrupted
Solution Approach 1:
The patent replaces manual handheld device operation with an automated optical system using thermal imaging cameras and computerized microprocessors. The system automatically captures thermal data from moving individuals through a constrained pathway, eliminating the need for manual intervention and achieving measurements within 500 ms without disrupting human flow.
2Measurement precision
If high resolution thermal imaging cameras are deployed to provide accurate thermal readings, then measurement precision improves, but device cost and deployment difficulty increase significantly
Solution Approach 1:
The patent employs multiple low-resolution thermal imaging cameras positioned at specific locations along a constrained pathway rather than using a single high-resolution camera. Each camera captures thermal data from a specific zone, and the computerized microprocessor integrates these localized measurements to provide accurate overall temperature assessment, reducing individual camera requirements and total system cost.
Solution Approach 2:
The measurement system is divided into multiple segments with individual cameras positioned at different locations. Each camera handles a portion of the measurement task, and the computerized microprocessor combines these segmented measurements to achieve the desired overall measurement precision, making the system more cost-effective and easier to deploy than a single high-resolution system.
3Productivity
If multiple thermal imaging cameras are positioned to capture dynamic thermal data from moving individuals, then measurement speed and continuity improve, but device complexity and geometric arrangement requirements increase
Solution Approach 1:
The patent designs the camera system to dynamically track and capture thermal data from moving individuals. The cameras are positioned to cover the constrained pathway where people walk, and the computerized microprocessor processes thermal data in real-time as individuals move through the measurement zone, maintaining measurement continuity without requiring complex mechanical tracking mechanisms.
