Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single sensor is used for measurement, then the device complexity is reduced, but the reliability of sensor data cannot be determined
Solution Approach 1:
The patent combines multiple sensors into a sensor array to determine the confidence level of measurements. By merging multiple sensing elements, the system achieves reliable data assessment through comparison of readings across sensors, resolving the contradiction between reliability and complexity.
Solution Approach 2:
The system implements feedback by continuously comparing measurements from multiple sensors and using this comparison to determine confidence levels. This feedback mechanism enables the system to self-assess data reliability without external intervention, addressing the reliability determination problem.
2Reliability
If multiple sensors are used to determine confidence level, then the reliability of sensor data is improved, but the device complexity increases
Solution Approach 1:
The patent segments the sensing function into multiple independent sensors within an array, allowing individual sensor performance to be evaluated separately. This segmentation enables reliability determination through comparison while maintaining manageable system complexity through modular architecture.
Solution Approach 2:
The sensor array system performs self-diagnosis by comparing its own sensor readings against each other to determine confidence levels. This self-service capability allows the system to assess its own reliability without requiring external monitoring equipment, thus improving reliability while controlling complexity.
3Measurement precision
If sensor measurements are used without confidence level determination, then the ease of operation is maintained, but the accuracy and safety of operations cannot be ensured
Solution Approach 1:
The patent introduces a confidence level determination mechanism as an intermediary between raw sensor measurements and operational decisions. This intermediary layer processes sensor data to assess accuracy without requiring operators to directly analyze multiple sensor readings, thus improving measurement precision while maintaining ease of operation.
