Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If relay device uses fixed network settings, then device complexity is reduced, but communication efficiency and reliability deteriorate under varying vehicle states
Solution Approach 1:
The patent implements dynamic network setting adjustment by having the control unit acquire relay-related information and vehicle state information, then obtain optimized network settings from an external server based on current operating conditions. This allows the relay device to adapt its network parameters dynamically rather than using fixed settings, resolving the contradiction between simplicity and reliability.
Solution Approach 2:
The system establishes a feedback loop where the control unit continuously monitors relay processing information and vehicle state, compares current performance with optimal settings obtained from external server, and adjusts network parameters accordingly. This feedback mechanism ensures communication reliability while maintaining manageable complexity through automated adjustment.
2Ease of operation
If network settings are manually configured, then ease of operation is improved, but adaptability to different vehicle states and communication demands deteriorates
Solution Approach 1:
The control unit automatically acquires relay-related information and vehicle state information, then autonomously obtains optimized network setting information from an external server without requiring manual intervention. The system self-adjusts network parameters based on current conditions, eliminating the need for complex manual configuration while achieving high adaptability to different vehicle states and communication demands.
3Device complexity
If relay device operates without update processing, then device complexity is reduced, but operational performance deteriorates
Solution Approach 1:
The system performs preliminary actions by continuously acquiring relay-related information and vehicle state information, then proactively obtaining optimized network setting information from an external server before performance degradation occurs. This preliminary adjustment of network parameters ensures optimal relay processing efficiency is maintained without requiring complex real-time update mechanisms during critical operations.
