Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual pairing and verification procedures are used, then verification accuracy can be ensured through user confirmation, but verification time and operational costs increase significantly
Solution Approach 1:
The system performs preliminary actions by automatically detecting the field device when the terminal enters the reception area and proactively initiating the coupling process without waiting for user input. The verification information is transmitted automatically once coupling is established, eliminating the need for manual initiation and significantly reducing verification time while maintaining reliability through automated confirmation protocols
Solution Approach 2:
The system enables self-service verification where the terminal device automatically performs the entire verification process independently. The terminal detects field devices, establishes coupling, transmits verification information, and completes the verification cycle without requiring user intervention, allowing the system to serve itself and eliminate manual operational overhead
2Ease of operation
If manual user guidance is required for verification, then user control over the verification process is maintained, but human resource requirements and operational complexity increase
Solution Approach 1:
The verification system performs self-service by automatically detecting field devices within reception area, initiating coupling processes, transmitting verification information, and completing verification cycles without requiring user control or intervention. This eliminates manual operational complexity while maintaining system reliability through automated protocols
3Reliability
If frequent verification is performed manually, then operational reliability improves, but personnel resource requirements and verification costs increase
Solution Approach 1:
The terminal device performs self-service verification by automatically detecting field devices when entering reception areas and completing verification processes without personnel intervention. This enables frequent verification across multiple field devices using existing terminal traffic patterns, significantly improving operational reliability while eliminating additional personnel resource requirements
Solution Approach 2:
The system enables continuous verification by leveraging the ongoing movement of terminal devices through the facility. As terminals naturally move through reception areas of various field devices, verification occurs continuously without interruption or additional resource allocation, maintaining high operational reliability
