Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If automated-driving vehicles equipped with wireless communication devices are deployed to reinforce wireless communication networks, then user convenience of wireless communication is enhanced, but system complexity and deployment cost increase
Solution Approach 1:
The automated-driving vehicle is designed to perform multiple functions: automated driving service and mobile wireless communication relay. The wireless communication device mounted on the vehicle enables it to function as both a transportation tool and a communication infrastructure element, allowing one system to serve multiple purposes and reducing the need for separate dedicated communication vehicles.
Solution Approach 2:
The vehicle autonomously navigates to locations with low radio wave intensity based on information from the server, and automatically provides wireless communication relay services without requiring manual intervention. The system self-organizes by having the server allocate vehicles based on real-time communication needs, reducing operational complexity.
2Reliability
If vehicles are dispatched to areas with low radio wave intensity, then wireless communication coverage is improved, but vehicle utilization efficiency decreases
Solution Approach 1:
The vehicle dispatch system dynamically adjusts vehicle allocation based on real-time wireless communication needs. The server receives information about areas with low radio wave intensity and automatically dispatches vehicles to those locations, creating a flexible system that adapts to changing communication demands rather than using fixed routing patterns.
Solution Approach 2:
The system implements a feedback mechanism where the server receives information about radio wave intensity levels from various locations and uses this information to make intelligent dispatch decisions. This feedback loop ensures vehicles are sent only where needed, optimizing both communication coverage and vehicle utilization by avoiding unnecessary deployments.
