Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional imaging technologies are used, then image reconstruction can be performed, but beam pattern variability is limited and electromagnetic wave interaction with scattering and reflector antennas is insufficient
Solution Approach 1:
The antenna system is segmented into multiple independent scattering elements and reflector elements, each capable of individual control. This segmentation enables independent adjustment of beam patterns while maintaining overall system functionality, directly addressing the need for beam pattern variability without requiring a completely new system design.
Solution Approach 2:
The scattering elements and reflector elements are configured with adjustable electromagnetic properties, allowing dynamic reconfiguration of beam patterns. This dynamic capability enables the system to adapt beam patterns to different imaging requirements while using the same physical hardware, resolving the contradiction between versatility and complexity.
2Productivity
If compressive imaging algorithms are used, then image reconstruction efficiency can be improved, but limitations remain in beam pattern variability and electromagnetic wave interaction
Solution Approach 1:
The system incorporates feedback mechanisms where the detector receives electromagnetic energy from multiple beam patterns and feeds this information back to the control system. This feedback enables iterative optimization of beam patterns to enhance image reconstruction efficiency while maintaining beam pattern variability through algorithmic control.
Solution Approach 2:
The system changes electromagnetic parameters such as frequency, amplitude, and phase of the scattered and reflected waves to create varied beam patterns. These parameter changes are controlled to work synergistically with compressive imaging algorithms, improving both reconstruction efficiency and beam pattern variability simultaneously.
3Reliability
If scattering elements and reflector elements are used, then electromagnetic wave interaction can be enhanced, but device complexity increases
Solution Approach 1:
The scattering elements and reflector elements are designed with multi-functionality, serving both as electromagnetic wave manipulators and as controllable beam pattern generators. This universal design reduces the need for separate specialized components, thereby enhancing electromagnetic wave interaction while limiting the increase in overall device complexity.
