Dynamic Reference Temperature for Body Abnormality Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing techniques for detecting body temperature abnormalities in individuals fail to consider the natural variation of body temperature based on a person's state, leading to inaccurate detection.
Innovation Solution
A communication device equipped with a first sensor to measure a person's state and a second sensor to measure body temperature, which compares reference body temperatures stored for specific states with actual body temperatures to determine abnormalities, generating alerting information when deviations are detected.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If body temperature is detected using fixed reference values, then the detection process is simple, but detection accuracy deteriorates due to ignoring natural temperature variation
Solution Approach 1:
The patent applies dynamics by transitioning from a static reference temperature value to a dynamic reference temperature that varies based on the person's state (e.g., waking, sleeping, eating). The system determines the appropriate reference temperature dynamically according to the detected state, allowing accurate abnormality detection across different physiological conditions without requiring multiple fixed reference values.
Solution Approach 2:
The patent changes the parameter of reference temperature based on the person's state. Instead of using a single fixed reference temperature, the system selects different reference temperatures corresponding to different states (waking, sleeping, eating, etc.). This parameter change enables accurate detection while managing complexity by organizing reference values in a structured manner.
2Measurement precision
If multiple reference body temperatures for different states are stored and used, then detection accuracy improves, but system complexity increases
Solution Approach 1:
The patent segments the body temperature detection system into distinct functional components: a sensor for detecting body temperature, a sensor for detecting person state, a determination unit for identifying the appropriate reference temperature based on state, and an abnormality determination unit. This segmentation organizes the multiple reference temperatures and their corresponding states in a manageable structure, reducing operational complexity while maintaining high detection accuracy.
