Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If metallic separators are used to separate transmitter and receiver antenna arrays, then interference effects are limited or avoided, but device complexity increases
Solution Approach 1:
The antenna array is divided into separate transmitter and receiver segments with metallic separators between them. This segmentation physically isolates the transmit and receive functions, reducing mutual interference while maintaining operational effectiveness of each segment.
Solution Approach 2:
Metallic separators are introduced as intermediary elements between transmitter and receiver antenna arrays. These separators act as electromagnetic shields that block or attenuate interference signals without significantly affecting the desired communication signals, thus mediating the interaction between transmit and receive functions.
2Productivity
If beamforming techniques are employed to improve communication efficiency, then productivity increases, but device complexity increases
Solution Approach 1:
Multiple antenna elements are merged into unified transmitter and receiver arrays with coordinated beamforming capabilities. By combining the arrays under a shared control architecture, the system achieves enhanced communication efficiency through spatial processing while avoiding the complexity of completely independent array controls.
Solution Approach 2:
The antenna arrays are designed to serve multiple functions: they perform both transmission and reception operations, support beamforming for directional communication, and enable interference cancellation. This multi-functionality increases productivity while managing complexity through unified array structures.
3Reliability
If interference cancellation techniques are applied, then reliability improves, but device complexity increases
Solution Approach 1:
The system employs feedback mechanisms where received signals are processed to identify interference components, which are then subtracted from the original received signals. This feedback loop continuously adjusts to maintain reliable communication by canceling out interfering signals in real-time.
Solution Approach 2:
The interference cancellation approach combines multiple processing techniques including beamforming, signal filtering, and adaptive interference subtraction. This composite processing strategy enhances reliability by addressing interference from multiple angles simultaneously, managing complexity through integrated processing.

Implementation Method 1
a separation by a metallic separator blocks line-of-sight transmission of radio signalling between the separated antenna arrays
Implementation Method 2
the antenna arrays have multiple antenna elements, and/or are adapted for beamforming
