Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple radio frequency circuits share multiple antennas with fixed connections, then the device structure is simple, but some antennas remain unused when radio frequency circuits are idle
Solution Approach 1:
The patent implements dynamic connection configuration between radio frequency circuits and antennas using switches. The connection topology changes based on which circuits are active or idle, allowing the system to adapt its antenna allocation in real-time. This dynamic switching mechanism enables full utilization of all antennas regardless of circuit states, resolving the contradiction between adaptability and complexity.
Solution Approach 2:
The patent creates a universal connection framework where any radio frequency circuit can be connected to any antenna through the switch matrix. This multi-functional connection capability ensures that when some circuits are idle, their associated antennas can be reassigned to active circuits, maximizing overall antenna utilization while maintaining a standardized connection structure.
2Productivity
If radio frequency circuits are connected to antennas without dynamic reconfiguration, then the connection structure is simple, but signal transmission efficiency decreases when circuits are idle
Solution Approach 1:
The system dynamically reconfigures signal transmission paths based on the operational state of radio frequency circuits. When circuits transition between active and idle states, the switch matrix automatically reroutes signals to maintain optimal transmission efficiency, ensuring that no antenna remains unused while managing the complexity through automated control.
