Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If different sub-networks with distinct protocols are used for data network and control network, then each network can maintain its specialized characteristics and performance, but interoperation between networks becomes complex and requires multiple heterogeneous sub-networks
Solution Approach 1:
The patent introduces a gateway device as an intermediary between the data network (TCP/IP-based) and control network (LonTalk-based). The gateway performs protocol conversion, translating packets from one protocol to another, enabling interoperation without compromising the specialized characteristics of each network. This mediator approach resolves the contradiction by maintaining network reliability through protocol specialization while reducing structural complexity through centralized conversion.
2Adaptability or versatility
If protocol conversion is implemented to enable interoperation between heterogeneous networks, then network compatibility improves, but the complexity of protocol analysis and conversion increases
Solution Approach 1:
The gateway device segments the protocol conversion process into distinct functional modules: a packet reception unit that receives packets from either network, a protocol analysis unit that identifies and analyzes the source protocol, and a packet transmission unit that converts and transmits to the target network. This segmentation makes the complex conversion process manageable and maintainable while improving compatibility.
Solution Approach 2:
The protocol analysis unit changes parameters of the received packet based on the identified protocol type. It analyzes protocol-specific parameters and transforms them into the corresponding parameters of the target protocol, enabling flexible adaptation between different network protocols while managing conversion complexity through systematic parameter transformation.
3Productivity
If standardization is pursued for data representation between measuring instruments and control systems, then information exchange efficiency improves, but the diversity of existing protocols and specialized characteristics may be compromised
Solution Approach 1:
The gateway device is designed with universal functionality to handle multiple protocol types. It can receive packets from both TCP/IP-based data networks and LonTalk-based control networks, perform protocol conversion, and transmit to the appropriate network. This multi-functionality enables efficient information exchange across heterogeneous networks while preserving protocol diversity through adaptive conversion capabilities.
