Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a new function unit is added to the vehicle network, then the network functionality and versatility are improved, but the network configuration complexity and potential for communication delays increase
Solution Approach 1:
The management device automatically detects the addition of new function units, acquires their network configuration information, and generates updated configuration information without manual intervention. The system serves itself by autonomously adapting to network changes, eliminating the need for complex manual reconfiguration processes.
Solution Approach 2:
The management device proactively detects new function units as soon as they are added to the network and immediately initiates the configuration update process. By performing the detection and configuration generation in advance, before communication delays can occur, the system maintains optimal network performance.
2Manufacturing precision
If manual network reconfiguration is performed when adding new function units, then configuration accuracy can be maintained, but time loss and operational efficiency decrease
Solution Approach 1:
The patent replaces the manual mechanical process of network reconfiguration with an automated information processing system. The management device uses detection units to automatically identify new function units and generation units to automatically create configuration information, substituting human operators with an automated computational system that maintains accuracy while eliminating time loss.
Solution Approach 2:
The management device acts as an intermediary between new function units and the existing network infrastructure. It automatically acquires network configuration information from the lower layers and generates appropriate configuration data, mediating the integration process without requiring manual intervention while ensuring configuration accuracy.
3Ease of operation
If network configuration below application layer is not considered, then reconfiguration process is simplified, but communication delays occur in high-importance data
Solution Approach 1:
The patent segments the network configuration into multiple layers, specifically considering the application layer and the lower layers (data link layer and physical layer). By dividing the configuration process into distinct segments, the system can automatically handle each layer's specific requirements, ensuring that communication reliability is maintained while keeping the overall process manageable.
Solution Approach 2:
The patent adds the dimension of lower-layer network configuration to the reconfiguration process. Instead of only considering application-layer settings, the system now operates in an expanded configuration space that includes data link layer and physical layer parameters, ensuring comprehensive network optimization without sacrificing communication reliability.

AI summary
A network of a new configuration is flexibly constructed while maintaining a stable operation in the network. A management device includes: a detection unit that detects addition of a function unit to a network including one or a plurality of on-vehicle function units; an acquisition unit that acquires function unit information of a new function unit that is the function unit the addition of which has been detected by the detection unit and function unit information of each on-vehicle function unit, each piece of function unit information including information regarding network configuration of a layer lower than an application layer; and a generation unit that, based on the pieces of function unit information acquired by the acquisition unit, generates configuration information of a new network that is the network further including the new function unit.
