Cold Syndrome Screening via Asymmetric EIFU Temperature and Pharynx Discomfort
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for determining the severity of cold syndrome infections, such as coronavirus, rely on axillary temperature measurements, which are inadequate as they do not accurately differentiate between true and pseudo-positive cases and fail to consider the balance between right and left body temperatures and subjective symptoms.
Innovation Solution
A screening apparatus that measures surface temperatures of right and left EIFU points and combines this data with subjective discomfort information from the pharynx regions to calculate temperature differences and coincidence levels, outputting severity information for medication guidance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If axillary temperature measurement is used to determine medication necessity, then the measurement method is simple and easy to implement, but the accuracy in differentiating true positive from pseudo positive cases is insufficient
Solution Approach 1:
The patent divides the temperature measurement into multiple locations (right EIFU, left EIFU, and axillary temperature) rather than relying on a single measurement point. This segmentation allows for more comprehensive evaluation of the subject's thermal state, improving the accuracy of true positive differentiation while maintaining relatively simple measurement procedures at each location.
Solution Approach 2:
The patent introduces the concept of EIFU (External Indication of Fever Unconsciousness) points located behind the ears, which are specific local regions that provide unique thermal information. By measuring temperature at these specific local quality points rather than general body areas, the system achieves better diagnostic accuracy for distinguishing true positive cases.
2Loss of information
If only axillary temperature is measured, then the measurement process is quick and simple, but the ability to evaluate disease severity and provide personalized medication guidance is insufficient
Solution Approach 1:
The patent performs preliminary temperature measurements at multiple locations (right EIFU, left EIFU, and axillary) simultaneously or in rapid succession before comprehensive evaluation. This preliminary action captures all necessary thermal data points efficiently, reducing the overall time required while ensuring complete diagnostic information is gathered for personalized medication guidance.
Solution Approach 2:
The patent merges multiple temperature measurements (right EIFU, left EIFU, axillary) and combines them with subjective discomfort information into a unified evaluation system. This integration allows comprehensive diagnostic information to be processed together, providing complete assessment without requiring separate lengthy evaluation steps for each parameter.
3Measurement precision
If multiple temperature measurement points are used, then the diagnostic accuracy is improved, but the device complexity and measurement time increase
Solution Approach 1:
The patent uses the EIFU points behind the ears as intermediary measurement locations that are easily accessible and provide valuable thermal information. These intermediary points serve as bridges between simple axillary measurement and more complex internal body temperature measurement, achieving improved diagnostic accuracy through non-invasive external measurements at strategically selected locations.

AI summary
A screening apparatus for cold syndrome-positive people includes an EIFU temperature measurer having right and left temperature measuring parts; a calculation unit of that calculates a difference value between a right and left EIFU temperatures measured with the right and left temperature measuring parts; an input unit of left/right discomfort to which right discomfort information and left discomfort information on discomfort in a right pharynx region and a left pharynx region perceived by the cold syndrome positive person are input; a calculation unit of left/right discomfort that calculates a degree of coincidence between the right discomfort information and the left discomfort information; an evaluation unit that outputs information of severity based on the calculated difference value and the degree of coincidence; and a reporting unit that notifies severity of the cold syndrome-positive person based on the information of severity.
