Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If traditional communication infrastructure is deployed to expand network coverage, then network coverage and communication quality are improved, but deployment cost increases significantly
Solution Approach 1:
The patent transforms stationary base stations into mobile relay stations using vehicles. The base station can dynamically move to different locations to provide communication services, converting fixed infrastructure into a flexible, mobile system that reduces deployment costs while maintaining coverage expansion capabilities
Solution Approach 2:
The communication device in the vehicle serves multiple functions: it acts as both a mobile relay station for extending network coverage and an edge computing server for providing computing resources. This multi-functionality reduces the need for separate infrastructure deployments
2Reliability
If more communication infrastructures are deployed to ensure coverage in millimeter wave band, then communication quality is improved, but investment cost increases
Solution Approach 1:
Vehicles equipped with communication devices can autonomously provide communication services in areas with poor coverage. The mobile relay station self-organizes to extend the network coverage area without requiring manual infrastructure deployment in every location, reducing investment costs while maintaining communication quality
Solution Approach 2:
The mobile relay station acts as an intermediary between the core network and user devices in coverage-limited areas. It receives signals from the base station and relays them to user devices, enabling communication in millimeter wave bands without requiring direct base station deployment in every location
3Ease of manufacture
If infrastructure sharing is implemented to reduce introduction cost, then deployment cost is reduced, but system complexity increases
Solution Approach 1:
The patent separates the communication function from the vehicle's primary function. The communication device operates as an independent module that can be activated or deactivated based on service requirements, simplifying the management of infrastructure sharing by isolating the communication subsystem from the vehicle's other systems
