Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single type of burst wave is used for measurement, then the device complexity is reduced, but the measurement precision deteriorates because the burst wave is only sensitive in a specific range of physical property values
Solution Approach 1:
The patent applies parameter changes by switching between different burst wave types (first burst wave for first predetermined range, second burst wave for second predetermined range) to adapt to different physical property value ranges. This allows the measurement device to maintain high precision across a broader range of values by changing the wave parameters rather than using a single fixed configuration
Solution Approach 2:
The measurement device implements dynamics by dynamically selecting and switching between different measurement modes based on the measured physical property values. The control unit determines which burst wave type to use based on the current measurement context, making the system adaptive rather than static
2Measurement precision
If multiple burst wave types are used to cover different ranges, then the measurement precision across various ranges is improved, but the device complexity increases due to multiple measurement modes and control requirements
Solution Approach 1:
The measurement device achieves universality by designing a single device that can perform multiple measurement functions using different burst wave types. The control unit coordinates the switching between first and second measurement modes, allowing one device to handle multiple measurement scenarios that would otherwise require separate specialized devices
Solution Approach 2:
The system applies preliminary action by first measuring using one burst wave type and then determining whether to switch to another type based on the initial measurement results. This sequential approach with preliminary measurement helps manage complexity by making switching decisions based on actual measurement needs rather than requiring all modes to be simultaneously active

AI summary
A measurement device includes a measurement unit that measures a physical property of a measurement target by causing the measurement target to vibrate through an application of an ultrasonic wave, the measurement unit including a first mode that measures the physical property using a first burst wave sensitive in a first predetermined range of physical property values and a second mode that measures the physical property using a second burst wave sensitive in a second range of physical property values different from the first range, and a control unit that controls the measurement unit to execute at least one of the first mode and the second mode.
