Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wireless communication is implemented in field devices, then peer-to-peer real-time communication and diagnostics are enabled, but device complexity increases
Solution Approach 1:
The system is divided into field devices that perform sensing/control and a separate diagnostic system that performs analysis. The wireless adapter segments the communication function, allowing field devices to communicate wirelessly without embedding complex wireless capabilities in each device.
Solution Approach 2:
A wireless adapter serves as an intermediary component that enables wireless communication between field devices and the diagnostic system. This mediator handles the wireless protocol complexity externally, keeping field devices simple while enabling peer-to-peer communication.
2Reliability
If diagnostic capabilities are added to field devices, then process monitoring reliability improves, but device complexity increases
Solution Approach 1:
The diagnostic system acts as an intermediary that receives data from field devices and performs diagnostic analysis. This separates the diagnostic functionality from the field devices themselves, maintaining device simplicity while improving monitoring reliability through dedicated diagnostic capabilities.
Solution Approach 2:
The diagnostic system serves multiple functions including receiving data from multiple field devices, performing diagnostics on multiple process variables, and providing comprehensive monitoring. This universal diagnostic platform improves reliability without requiring each field device to be complex.
3Measurement precision
If information from multiple field devices is utilized, then diagnostic accuracy improves, but communication system complexity increases
Solution Approach 1:
The diagnostic system merges data from multiple field devices into a unified diagnostic analysis. By combining information from multiple sources, the system achieves higher diagnostic accuracy while the wireless adapter handles the complexity of integrating multiple communication channels.
