Engineering Contradiction Analysis
1Measurement precision
If multiple independent analyte sensors are used to monitor multiple analytes, then measurement precision for each analyte is improved, but device complexity and cost increase
Solution Approach 1:
The patent combines multiple analyte sensors into a single integrated sensor device that can simultaneously detect multiple analytes (glucose, ethanol, and other metabolites). This merging approach maintains the measurement precision of individual sensors while reducing the overall device complexity and eliminating the need for users to wear multiple separate sensors.
Solution Approach 2:
The integrated sensor system is designed with multi-functional capability to detect various analytes including glucose, ethanol, lactate, pyruvate, and other metabolites. This universal detection capability allows a single sensor to perform the functions of multiple specialized sensors, thereby reducing device complexity while maintaining comprehensive monitoring accuracy.
2Measurement precision
If multiple independent analyte sensors are used, then measurement precision is improved, but ease of operation deteriorates
Solution Approach 1:
By merging multiple sensor functions into a single wearable device, the patent eliminates the burden of wearing multiple separate sensors. Users experience improved ease of operation and comfort while the integrated sensor maintains high measurement precision for all monitored analytes through simultaneous detection capabilities.
3Measurement precision
If multiple independent analyte sensors are deployed, then reliability of individual sensor measurements is improved, but overall system reliability deteriorates
Solution Approach 1:
The patent integrates multiple sensing functions into a single cohesive system, thereby reducing the total number of potential failure points. While maintaining the measurement precision of individual analyte detectors, the unified architecture improves overall system reliability by eliminating the cumulative failure risk associated with multiple independent sensors.
4Adaptability or versatility
If multiple analyte sensors are used, then adaptability for monitoring different analytes is improved, but manufacturing precision requirements increase
Solution Approach 1:
The patent employs a universal sensor platform with multi-functional detection capabilities that can monitor various analytes including glucose, ethanol, lactate, and pyruvate. This approach achieves high adaptability through a standardized manufacturing process, actually reducing the precision requirements compared to producing multiple specialized sensors with different fabrication specifications.
