Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a vehicle connects to another vehicle using a different communication method to offload data, then wireless resource utilization is improved, but the area where connection is possible becomes extremely limited
Solution Approach 1:
The patent introduces a base station as an intermediary that provides condition information about relay vehicles. This mediator enables vehicles to identify suitable relay partners by receiving pre-evaluated condition information (communication capability, location, load status) from the base station, thereby expanding the effective connection area while maintaining efficient resource utilization through informed partner selection
2Ease of operation
If a vehicle selects a relay vehicle based on proximity, then connection establishment is simplified, but the relay vehicle may not be capable of communicating with the predetermined device
Solution Approach 1:
The base station performs preliminary evaluation and publishes condition information about relay vehicles before actual connection establishment. This preliminary action includes assessing communication capabilities, location, and load status, allowing vehicles to make informed selection decisions that ensure both ease of connection and reliability of the relay path
3Speed
If a communication device connects to another device without recognizing its connectability to the predetermined device, then connection speed is improved, but communication quality may be degraded due to unreliable relay devices
Solution Approach 1:
The system implements feedback through the base station that continuously monitors and publishes condition information about relay vehicles. This feedback mechanism provides real-time information about communication capability, location, and load status, enabling vehicles to quickly identify reliable partners while maintaining high connection speed through pre-evaluated information

AI summary
A communication device that performs communication wirelessly receives by using a first communication method, from a first another device, information regarding a condition for communication in a second communication method within a geographical range where communication with the first another device is possible, the second communication method being different from the first communication method, and selects a second another device that performs the communication in the second communication method, based on the information regarding the condition.
