Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional wearable pulse wave sensors are used, then basic pulse detection is achieved, but the ability to correlate pulse data with organ states or diseases is limited
Solution Approach 1:
The sensor is divided into multiple independent sensor units arranged in a row, with each unit capable of detecting pulse waves at different locations. This segmentation allows the system to capture spatial variations in pulse characteristics, enabling correlation with specific organ states and improving diagnostic capability by providing location-specific pulse data that can be analyzed individually.
Solution Approach 2:
The patent transitions from single-point pulse detection to multi-point spatial detection by arranging multiple sensor units in a row along the body surface. This adds a spatial dimension to pulse wave measurement, enabling the system to capture pulse characteristics at multiple locations simultaneously, which can then be correlated with organ health status and disease conditions.
2Measurement precision
If multiple sensor units are placed in a row to capture pulse waves at different locations, then diagnostic capability is improved, but device complexity increases
Solution Approach 1:
Multiple sensor units are integrated into a single unified sensor structure that can be applied as one device to the body surface. The sensor units share common components such as the substrate, encapsulation layers, and signal processing circuitry, reducing overall device complexity while maintaining the ability to detect pulse waves at multiple locations simultaneously.
Solution Approach 2:
Each sensor unit is designed with universal functionality to detect pulse waves, and the entire sensor array can be applied to different body locations depending on the diagnostic requirement. This multi-functional design allows the same basic sensor structure to serve multiple diagnostic purposes without requiring separate specialized devices for each function.
3Measurement precision
If dielectric pyramids and microhairs are incorporated into the sensor units, then sensitivity to pulse pressure is enhanced, but manufacturing precision requirements increase
Solution Approach 1:
The sensor units utilize dielectric pyramids and microhairs as structural elements that change their geometric parameters (such as surface area, height, or spacing) in response to pulse pressure. These parameter changes induce corresponding capacitance changes that can be measured, enhancing sensitivity to pulse pressure while using manufacturable geometric modifications rather than requiring complex material properties.
