Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a new function unit is added to the vehicle network, then network functionality and adaptability are improved, but communication delays may occur and network management complexity increases
Solution Approach 1:
The relay device performs preliminary actions by detecting the addition of a new function unit before normal communication occurs. The detection unit identifies the new function unit, and the acquisition unit proactively obtains network information about it, preparing the network for seamless integration and preventing communication delays during the transition phase.
Solution Approach 2:
The relay device acts as an intermediary between the new function unit and the existing network. It detects the new function unit, acquires its network information, and relays this information to appropriate devices, facilitating smooth integration without causing communication delays between the new unit and other network participants.
2Loss of information
If network information is acquired through traditional methods, then complete network configuration data can be obtained, but communication delays occur and integration efficiency decreases
Solution Approach 1:
The acquisition unit extracts only the necessary network information from frames transmitted by or to the new function unit, rather than acquiring complete network configuration data through traditional lengthy procedures. This selective extraction obtains essential information quickly, improving integration efficiency while maintaining information completeness.
Solution Approach 2:
The system skips traditional lengthy information acquisition procedures by obtaining network information directly from frames during normal communication operations. This rushing through the information acquisition process happens concurrently with regular network traffic, eliminating separate delays and improving overall integration speed.
3Measurement precision
If the relay device monitors all frames to detect new function units, then detection accuracy is improved, but device complexity and processing load increase
Solution Approach 1:
The relay device performs multiple functions using the same frame monitoring mechanism: it relays frames for normal communication, detects new function units, and acquires network information. This multi-functionality improves detection accuracy without significantly increasing device complexity, as the same infrastructure serves multiple purposes.
Solution Approach 2:
The detection and information acquisition functions are merged with the existing frame relay operation. Instead of separate monitoring systems, the relay device combines these functions into its normal frame handling process, maintaining detection accuracy while avoiding the complexity of additional independent processing systems.

AI summary
An information of a network to which a new function unit has been added is easily acquired. A relay device installed in a vehicle includes: a detection unit configured to detect a new function unit being a function unit that is newly added to a network including an existing function unit being one or a plurality of function units; a relay unit configured to relay a frame between the function units; and an acquisition unit configured to acquire, from the frame, relayed by the relay unit, between the new function unit detected by the detection unit and the existing function unit, function unit information that includes information regarding a network configuration of a layer of a lower order than an application layer, the function unit information being of at least one of the new function unit and the existing function unit.
