Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If additional temperature sensors are installed in the Coriolis measuring device, then temperature measurement capability is improved, but device complexity and susceptibility to errors increase
Solution Approach 1:
The patent combines the temperature measuring device with either the sensor or exciter into an integrated unit. The temperature measuring device shares the same housing and electrical connections as the sensor/exciter, eliminating the need for separate temperature sensor installations. This merging reduces the number of separate components while maintaining temperature measurement functionality.
Solution Approach 2:
The sensor or exciter is designed to perform multiple functions: both Coriolis measurement and temperature measurement. By integrating the temperature measuring device into the existing sensor/exciter structure, a single component serves dual purposes, reducing overall device complexity while providing comprehensive measurement capabilities.
2Measurement precision
If additional temperature sensors are installed in the Coriolis measuring device, then temperature measurement capability is improved, but manufacturing complexity increases
Solution Approach 1:
The temperature measuring device is manufactured as an integrated unit with the sensor or exciter. They share common housing structures, mounting arrangements, and electrical connection pathways. This combined manufacturing approach reduces the number of separate assembly operations and simplifies the manufacturing process compared to installing separate temperature sensors.
3Measurement precision
If additional cables are used for temperature sensors, then temperature measurement is enabled, but susceptibility to errors and complexity increase
Solution Approach 1:
The temperature measuring device shares the same electrical connections and cable pathways as the sensor or exciter. The housing provides a common sealed environment for both the Coriolis measurement electronics and temperature measurement electronics, reducing exposure to environmental errors and simplifying cable management.
