Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple antennas are provided for each communication service, then communication reliability and service coverage are improved, but production costs, vehicle weight, and installation space increase
Solution Approach 1:
The patent implements a shared antenna pool where a limited set of antennas serves multiple communication services through dynamic allocation. The base station controller assigns antennas to different users and services based on current communication needs, allowing the same physical antenna to be reused across multiple services and users, thereby reducing the total number of antennas required while maintaining service reliability
Solution Approach 2:
The system dynamically allocates antennas to communication services based on real-time operating parameters such as signal quality, user location, and service requirements. The base station controller continuously monitors communication conditions and reassigns antennas as needed, enabling flexible adaptation without requiring dedicated antennas for each service
2Adaptability or versatility
If dedicated antennas are assigned to each communication service, then service independence and performance are improved, but device complexity and cabling requirements increase
Solution Approach 1:
The patent merges multiple service-specific antenna connections into a single shared antenna pool connected to the base station. Instead of having separate cabling for each service-antenna pair, all communication services share common cabling infrastructure to access the shared antenna pool, significantly reducing cabling complexity while the base station controller maintains service independence through software-based resource allocation
3Productivity
If more antennas are installed to handle increasing communication services, then service capacity is improved, but production costs and installation space increase
Solution Approach 1:
The system enables a fixed number of antennas to serve an increasing number of communication services through dynamic allocation and multiplexing. The base station controller manages the shared antenna pool to accommodate multiple services and users simultaneously, allowing service capacity to scale without proportionally increasing the number of physical antennas, thereby reducing production costs
Solution Approach 2:
The system changes operational parameters such as frequency allocation, time slots, and antenna assignment to increase service capacity from a fixed antenna infrastructure. By dynamically adjusting these parameters, the system can accommodate more communication services without adding physical hardware, reducing manufacturing and installation costs
