Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If preterminated cables with RFID tags are used, then installation time and cost are reduced, but the complexity of the system increases due to automated detection and tracking requirements
Solution Approach 1:
Cables are preterminated with connectors and RFID tags attached before installation. The RFID tags are pre-programmed with identification information, allowing cables to be quickly connected without field assembly, thus reducing installation time while the automated detection system manages the complexity
Solution Approach 2:
RFID tags serve as intermediaries between the physical cable and the management system. They carry identification information that enables automated detection and tracking without requiring complex manual tracking processes, bridging the gap between simple cable installation and sophisticated network management
2Ease of manufacture
If lower-skill installation crews are used, then installation cost is reduced, but the risk of improper interconnection increases
Solution Approach 1:
The cable connector and patch panel work together to automatically perform identification and verification functions. The RFID tag on the cable self-identifies to the patch panel reader, and the system automatically logs the interconnection, eliminating the need for skilled manual tracking and verification while ensuring proper connections
Solution Approach 2:
The automated detection system provides immediate feedback when a cable is connected or disconnected by reading the RFID tag and updating the database. This real-time feedback ensures that interconnections are properly recorded and tracked, maintaining reliability even with lower-skill installation crews
3Device complexity
If manual tracking of cable interconnections is used, then system complexity is reduced, but time consumption for management increases
Solution Approach 1:
Manual mechanical tracking processes are replaced with an automated electronic detection system using RFID tags and readers. The system automatically reads tag information and logs interconnections in a database, eliminating time-consuming manual record-keeping while managing complexity through software automation
Solution Approach 2:
The automated detection system performs multiple functions: identifying cables, tracking interconnections, logging data, and providing real-time network status information. This multi-functional system consolidates what would otherwise require separate manual processes, reducing management time while the software manages the complexity
