Solution Overview
Problem
Biometric sensors in electronic devices can only provide limited information such as heartbeat or oxygen saturation, and are unable to measure or analyze other important metrics like glucose, water, or fat levels, lacking the capability for comprehensive biometric data comparison and analysis.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a biometric sensor is used to obtain basic biometric information, then heartbeat and oxygen saturation can be measured, but the device cannot measure or analyze other important metrics like glucose, water, or fat levels
Solution Approach 1:
The patent implements a multi-functional sensor system that can measure multiple types of biometric information (heartbeat, oxygen saturation, glucose, water, fat levels) using a single integrated device. The sensor module is designed to detect various wavelengths of light and process them to extract different biometric parameters, making the device universal rather than limited to specific measurements
2Ease of operation
If a biometric sensor delivers basic biometric information to the user, then simple data transmission is achieved, but the device cannot compare or analyze the pieces of biometric information obtained
Solution Approach 1:
The patent introduces an intermediary processing system that bridges the gap between simple data delivery and complex analysis. The sensor module collects raw biometric data, which is then processed by analysis circuits that compare and interpret the information. This intermediary layer enables sophisticated analysis (comparing multiple biometric parameters) without requiring the entire system to be overly complex, as the analysis function is separated into dedicated processing components
