Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional transmitter array antenna is used, then the structure is simple, but simultaneous bidirectional communication capability is lacking
Solution Approach 1:
The antenna cell is segmented into separate transmission and reception channels, each with dedicated antenna elements and phase shift and amplification circuits. This segmentation allows independent optimization of transmit and receive paths, enabling simultaneous bidirectional communication while maintaining manageable complexity through modular design
Solution Approach 2:
The invention introduces polarization diversity as an additional dimension for signal separation. By using antenna elements with different polarization orientations (e.g., horizontal and vertical), the system can simultaneously transmit and receive signals on the same frequency without interference, adding a new degree of freedom to resolve the communication direction conflict
2Adaptability or versatility
If separate transmission and reception channels are implemented, then simultaneous bidirectional communication is enabled, but device complexity increases
Solution Approach 1:
Each antenna element and associated phase shift and amplification circuit is designed to serve dual functions: transmitting signals in one direction and receiving signals in the opposite direction. This multi-functionality reduces the need for completely separate hardware paths, as each component participates in both transmission and reception operations depending on the signal direction
Solution Approach 2:
The invention merges the transmission and reception functions into a unified antenna cell structure where phase shift and amplification circuits handle both transmit and receive signals. By combining these functions in a integrated manner rather than using completely separate systems, the overall device complexity is reduced while maintaining bidirectional capability
3Object-generated harmful factors
If polarization diversity is used for signal separation, then interference cancellation improves, but manufacturing precision requirements increase
Solution Approach 1:
Different antenna elements within the same cell are assigned different polarization orientations (e.g., one element horizontal, another vertical) to create local quality differences. This local polarization differentiation enables signal separation and interference cancellation, as each element responds preferentially to signals with its matching polarization, reducing cross-interference without requiring extreme manufacturing precision
