Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single sensor is used for measurement, then the device complexity is reduced, but the measurement precision and reliability deteriorate due to position and size influences
Solution Approach 1:
The patent divides a single sensor into multiple sensors arranged in an array configuration. Each sensor measures biological information from a specific location, and the measurements are combined to achieve comprehensive and accurate measurement across the entire measurement area, resolving the contradiction between device simplicity and measurement precision.
Solution Approach 2:
The patent combines measurements from multiple sensors to achieve comprehensive biological information measurement. By merging data from multiple sensor elements, the system overcomes the limitations of single-sensor measurements and achieves both simplicity and precision.
2Device complexity
If a single sensor covers a large area, then the device complexity is reduced, but the measurement precision deteriorates due to position dependence
Solution Approach 1:
The patent segments the measurement area into multiple zones, each monitored by a dedicated sensor. This segmentation eliminates position dependence because each sensor is optimized for its specific location, and the collective data achieves high precision across the entire area.
Solution Approach 2:
The patent applies local quality by having each sensor in the array optimized for its specific measurement location. Each sensor element provides high-quality local measurements, and the aggregation of these localized measurements achieves comprehensive precision across the entire measurement area.
3Measurement precision
If multiple sensors are used to improve measurement accuracy, then the measurement precision improves, but the device complexity increases
Solution Approach 1:
The patent makes each sensor element multi-functional, capable of measuring multiple biological parameters (temperature, oxygen saturation, heart rate) simultaneously. This universality reduces device complexity because a single sensor array structure serves multiple measurement functions, eliminating the need for separate sensor systems for each parameter.
Solution Approach 2:
The patent merges multiple measurement functions into a unified sensor array system. By combining temperature, oxygen saturation, and heart rate measurements in a single integrated array, the system achieves high precision for multiple parameters without proportionally increasing device complexity.
4Adaptability or versatility
If conventional multi-measurement sensors are used, then various biological information can be acquired, but the reliability deteriorates due to single-sensor limitations
Solution Approach 1:
The patent segments the measurement function across multiple sensor elements, each contributing to the overall measurement of temperature, oxygen saturation, and heart rate. This segmentation improves reliability because the system can aggregate data from multiple locations, reducing the impact of any single sensor's limitations or positioning errors.
Solution Approach 2:
The patent combines measurements from multiple sensor elements to achieve reliable multi-parameter monitoring. By merging data from multiple locations simultaneously, the system achieves both versatility in measuring multiple biological parameters and reliability through redundant measurement paths.
