Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple sensors are placed on different body locations for comprehensive monitoring, then measurement precision and data comprehensiveness are improved, but device complexity and manufacturing difficulty increase
Solution Approach 1:
The patent combines multiple sensor types (electrochemical analyte sensor and optical sensor) into a single integrated sensor device that can be placed at one body location. The electrochemical sensor measures analyte concentration while the optical sensor measures physiological parameters such as blood oxygen saturation, heart rate, and activity levels. This merging approach achieves comprehensive monitoring data without requiring multiple separate sensors on different body locations, thereby reducing system complexity and manufacturing difficulty while maintaining measurement precision.
2Loss of information
If multiple sensors are used for comprehensive data tracking, then data comprehensiveness is improved, but ease of manufacture deteriorates
Solution Approach 1:
The sensor device is designed with multi-functionality, where a single device performs multiple measurement functions. The electrochemical sensor provides analyte concentration measurement, while the optical sensor simultaneously provides physiological parameter measurements including blood oxygen saturation, heart rate, and activity detection. This universal design allows one device to replace multiple specialized sensors, improving data comprehensiveness while simplifying manufacturing processes and reducing assembly complexity.
3Loss of information
If integrated sensor systems are implemented for comprehensive monitoring, then data tracking capability is improved, but device complexity increases
Solution Approach 1:
The patent merges the electrochemical sensing system and optical sensing system into a single integrated device with shared structural components and housing. Both sensor types are positioned to contact the same body tissue area, allowing simultaneous data collection. The integration is achieved through common mechanical support structures and unified positioning mechanisms, which reduce the overall system complexity compared to using separate devices while maintaining comprehensive continuous data tracking capability.
