Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple sensors are used to monitor various biometric information types, then measurement capability is improved, but device size increases
Solution Approach 1:
The patent combines multiple sensor functions into a single sensor unit that can detect various biometric information types (heart rate, blood sugar, calories, vein images) simultaneously. This is achieved by integrating multiple wavelength detection capabilities and filter systems within one sensor module, thereby maintaining measurement versatility while reducing overall device size.
Solution Approach 2:
The sensor unit is designed with multi-functional capability to perform multiple measurement tasks using a single device. By incorporating filters for different wavelength ranges and using a unified sensor structure, the system can monitor various biometric parameters without requiring separate dedicated sensors for each function.
2Volume of moving object
If a single sensor is used to monitor multiple biometric information types, then device size is reduced, but measurement precision deteriorates
Solution Approach 1:
The sensor unit is divided into multiple regions, each equipped with specific filters for detecting different wavelength ranges. This segmentation allows the single sensor to simultaneously perform specialized measurements for different biometric parameters, maintaining high measurement precision for each function while using a compact unified structure.
Solution Approach 2:
Different regions within the sensor unit are configured with specific optical filters tailored to detect particular wavelength ranges corresponding to different biometric measurements. This local specialization ensures that each measurement function maintains high precision while being integrated within the compact sensor unit.
