Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If data is transmitted through narrowband connections (dial-up telephone lines), then remote gas turbines can be monitored, but data transmission speed and reliability deteriorate due to limited bandwidth
Solution Approach 1:
A gateway device acts as an intermediary between narrowband and broadband networks. The gateway receives data packets from the narrowband dial-up connection, buffers them, and then transmits them through a broadband connection to the remote monitoring system, thereby overcoming the bandwidth limitations of the narrowband connection while maintaining remote monitoring capability
Solution Approach 2:
The data transmission path is segmented into two independent connections: a narrowband dial-up connection for data collection at the gas turbine site, and a broadband connection for high-speed data transmission to the monitoring system. This segmentation allows each connection to operate at its optimal speed without being constrained by the other
2Adaptability or versatility
If data is transmitted through narrowband connections, then remote monitoring is enabled, but data loss increases due to bandwidth limitations
Solution Approach 1:
The gateway device buffers incoming data packets from the narrowband connection before transmission through the broadband connection. This preliminary buffering action ensures that data is ready for immediate transmission when the broadband connection is available, preventing data loss due to narrowband bandwidth limitations
Solution Approach 2:
The gateway serves as a mediator that manages the data flow between the narrowband and broadband networks, ensuring reliable data transmission by handling packet buffering, error checking, and retransmission if necessary
3Productivity
If UDP protocol is used for data transmission, then transmission speed is improved, but data loss increases due to lack of error handling
Solution Approach 1:
The gateway device acts as a reliable intermediary that implements error handling and data integrity checks. It receives UDP packets from the narrowband connection, verifies their integrity, and ensures reliable delivery through the broadband connection, thereby maintaining both the speed benefits of UDP and the reliability needed for critical data
