Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If different communication protocols are used for various application service nodes, then the adaptability of the system to different communication requirements is improved, but the device complexity and difficulty of configuration and debugging increase
Solution Approach 1:
The patent introduces a gateway as an intermediary component between application service nodes using different communication protocols. The gateway performs protocol conversion and data routing, allowing nodes to communicate without direct protocol compatibility. This mediator approach resolves the contradiction by maintaining protocol diversity while simplifying the configuration burden on individual nodes.
Solution Approach 2:
The gateway is designed with multi-functional capabilities to handle multiple communication protocols simultaneously. It provides universal interface adaptation, data routing, and protocol conversion functions that work across different protocol types. This universality allows the system to support diverse protocols without proportionally increasing configuration complexity.
2Adaptability or versatility
If different communication protocols are used for various application service nodes, then the flexibility of data transmission is improved, but the reliability of data transmission decreases due to increased errors
Solution Approach 1:
The gateway acts as a reliable intermediary that ensures accurate data transmission between nodes using different protocols. It performs validation, error checking, and proper protocol conversion to prevent transmission errors. This mediator approach maintains flexibility in protocol selection while ensuring reliability through centralized control and validation.
Solution Approach 2:
The system implements feedback mechanisms where the gateway monitors data transmission status and provides error reporting. When transmission errors occur, the feedback loop enables error correction and retransmission. This feedback approach maintains transmission flexibility while improving reliability through active error management.
3Adaptability or versatility
If multiple communication protocols are supported, then the extensibility of the vehicle network is improved, but the difficulty of detecting and measuring transmission errors increases
Solution Approach 1:
The gateway centralizes error detection and measurement functions, providing a single point for monitoring transmission quality across all protocol types. This intermediary approach maintains network extensibility while simplifying error detection by consolidating diagnostic capabilities in the gateway rather than requiring each node to independently detect errors across multiple protocols.
Solution Approach 2:
The gateway provides a unified interface and standardized error reporting mechanism for all communication protocols. By homogenizing the error detection and reporting format across different protocols, the system maintains extensibility while reducing the complexity of error detection and analysis.

AI summary
A method for transmitting data includes receiving a data transmission request from a target service node. The data transmission request carries a target interface descriptor. The target interface descriptor includes a target resource location address and a target communication protocol type. The target interface descriptor is a common descriptor used by a vehicle network to which the target service node belongs. The target interface descriptor further includes a communication parameter. The method also includes in response to the data transmission request, forwarding data between the target service node and a target resource location corresponding to the target resource location address using a target communication protocol corresponding to the target communication protocol type in a plurality of preset communication protocols.
