Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a transmission line is connected between each measuring device and the recorder, then measured values can be transmitted reliably, but wiring costs and installation complexity increase
Solution Approach 1:
Multiple measuring devices (flowmeter, temperature sensor, pressure sensor, conductivity sensor, pH sensor) are merged into a single integrated field device housing, sharing common wiring and power supply. This consolidation reduces the number of transmission lines from multiple individual connections to a single unified connection, thereby reducing wiring costs and installation complexity while maintaining reliable data transmission from all sensors.
Solution Approach 2:
The field device is designed as a multi-functional unit that performs multiple measurement functions (flow, temperature, pressure, conductivity, pH) within a single device. This universal design allows one transmission line to carry data from multiple sensor types, eliminating the need for separate wiring for each measuring device and reducing overall system complexity.
2Adaptability or versatility
If multiple types of sensors are installed, then comprehensive measurement data can be obtained, but the number of transmission lines and wiring work increase
Solution Approach 1:
The patent combines multiple sensor types (flow, temperature, pressure, conductivity, pH) into a single integrated field device. This merging approach maintains comprehensive measurement capability while reducing installation complexity, as all sensors share common mounting infrastructure and a single transmission line connection to the recorder.
Solution Approach 2:
The field device internally segments different sensor functions into separate measurement modules while maintaining a unified external interface. This segmentation allows each sensor type to operate independently with its own processing circuitry, yet all data can be transmitted through a single consolidated connection, preserving versatility while simplifying installation.
