Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If a reconfigurable reflector is used for beam forming at high carrier frequencies, then transmission capacity is improved, but transmission loss increases
Solution Approach 1:
The patent combines a reconfigurable reflector with an amplifier to create an integrated system. The amplifier compensates for the transmission loss inherent in high carrier frequency operations, allowing the system to maintain both high transmission capacity and acceptable signal strength. This merging of components resolves the contradiction by adding functionality that directly addresses the loss problem while preserving the beam forming capability.
2Productivity
If the beam area coverage is limited, then the incident beam can be concentrated, but the utilization of unit reflectors is reduced
Solution Approach 1:
The patent employs dynamic control of the reconfigurable reflector to adapt the beam area coverage to match the incident beam characteristics. By dynamically adjusting which unit reflectors are active and how they are configured, the system can expand or contract the effective reflector area as needed. This dynamic adaptation allows full utilization of available unit reflectors when incident beam coverage is limited, while maintaining control efficiency through optimized activation patterns.
3Measurement precision
If a separate algorithm is used to detect incident beam distribution, then phase change control is achieved, but system complexity and cost increase
Solution Approach 1:
The patent implements a self-service mechanism where the reconfigurable reflector system automatically detects and adapts to incident beam distribution without requiring external detection algorithms. The amplifier and controller work together to sense the incident beam characteristics and automatically adjust the phase change of each unit reflector accordingly. This self-service approach eliminates the need for separate complex detection algorithms while maintaining precise phase change control, thereby reducing system complexity and cost.
