Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If optical antenna elements are arranged in arrays with phase adjusters and combiners to achieve beamforming and beamsteering, then beam control capability and coherence are improved, but device complexity increases
Solution Approach 1:
The optical antenna system is divided into multiple individual optical antenna elements, each capable of independent phase adjustment. These segmented elements work together in arrays to achieve beamforming and beamsteering capabilities while maintaining manageable complexity through modular design
Solution Approach 2:
The system incorporates dynamic phase adjusters that can modify the phase of individual optical antenna elements in real-time. This dynamic control enables adaptive beamforming and beamsteering, allowing the system to adjust beam direction and focus without physical reconfiguration
2Manufacturing precision
If phase adjusters and combiners are used to control relative phases of optical antenna elements, then coherence and beamforming efficiency are improved, but manufacturing complexity increases
Solution Approach 1:
The system controls phase relationships by adjusting the optical path length parameter for each antenna element. By changing this physical parameter through adjustable path lengths, the system achieves precise phase control without requiring complex manufacturing tolerances on the antenna elements themselves
3Reliability
If optical antenna assemblies are designed for precise beam control and coherent light generation, then beamforming performance is improved, but the system becomes more complex and difficult to operate
Solution Approach 1:
The system incorporates feedback mechanisms that monitor the output of the optical antenna array and adjust the phase of individual elements accordingly. This feedback control maintains coherent beamforming performance automatically, reducing the operational complexity for users
