A multispectral blood metrics measurement system comprising an energy transmitter, energy receiver, and analyzer that projects energy at specific wavelengths associated with nutrients in the blood, detects the reflected energy, and determines nutrient concentrations, enabling the measurement of various blood metrics like glucose, hemoglobin, and cholesterol, with a user interface for displaying results and generating alerts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If non-invasive blood metric measurement is implemented, then health monitoring capability is improved, but measurement precision deteriorates
Solution Approach 1:
The measurement system segments the blood metric measurement into multiple wavelength components (first wavelength, second wavelength, and third wavelength) to measure different blood metrics simultaneously. This allows non-invasive monitoring of multiple parameters including blood glucose, oxygen saturation, and other hemodynamic parameters, improving health monitoring capability while maintaining measurement precision through multi-parameter analysis
Solution Approach 2:
The system transitions from single-wavelength measurement to multi-wavelength spectral measurement, adding the spectral dimension to the measurement process. By measuring at multiple wavelengths (first, second, and third wavelengths), the system extracts additional information about blood composition and hemodynamics, enabling non-invasive measurement of multiple blood metrics simultaneously
2Adaptability or versatility
If multispectral measurement system is implemented, then blood metric measurement capability is improved, but device complexity increases
Solution Approach 1:
The system merges multiple measurement functions into a single integrated device that can measure multiple blood metrics simultaneously. The energy transmitter combines multiple wavelength sources, the energy receiver captures signals at all wavelengths, and the analyzer processes all signals to determine multiple blood metrics including glucose, oxygen saturation, and other parameters, reducing the need for multiple separate devices
Solution Approach 2:
The measurement system is designed with universal functionality to measure multiple blood metrics using the same hardware platform. The energy transmitter, energy receiver, and analyzer are configured to handle multiple wavelengths and multiple measurement types, making the device versatile for monitoring various blood parameters without requiring separate specialized equipment for each metric
