Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual methods are used to read identification data and contact the manufacturer for activation codes, then the functionality can be expanded, but the process becomes complex and error-prone
Solution Approach 1:
The configuration device serves as an intermediary between the field device and the central station. It automatically reads identification data from the field device, transmits it to the central station, receives activation codes, and writes them back to the field device. This automated intermediary process eliminates the need for manual data reading, manufacturer contact, and code entry, thereby reducing process complexity while maintaining functionality expansion capability.
2Adaptability or versatility
If manual methods are used for functionality expansion, then activation codes can be obtained, but traceability is lost and errors increase
Solution Approach 1:
The system implements automated feedback loops where the configuration device reads identification data from the field device, transmits it to the central station, receives activation codes, and writes them back. This closed-loop automated process ensures traceability by automatically recording and transmitting all relevant data, eliminating manual transcription errors and providing a complete audit trail from field device to central station and back.
3Adaptability or versatility
If manual processes are used to order and receive activation codes, then functionality can be upgraded, but the process requires extensive manual intervention
Solution Approach 1:
The configuration device performs self-service by automatically reading identification data from the field device, formulating the request, transmitting it to the central station, receiving the activation code, and writing it back to the field device without requiring user intervention for each step. The user simply initiates the process and the system handles all subsequent manual tasks automatically, significantly reducing user effort while enabling functionality upgrades.
