Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple RF integrated circuits are used to control RF front end circuits, then control capability is improved, but device complexity increases
Solution Approach 1:
The patent divides the control function into multiple RF integrated circuits, each with dedicated control ports for specific RF front end circuits. This segmentation allows independent control of different components (e.g., first RF front end circuit controlled by first RF IC, second RF front end circuit controlled by second RF IC), improving control capability while managing complexity through functional separation.
2Adaptability or versatility
If all components are kept active for potential processing, then adaptability is improved, but power consumption increases
Solution Approach 1:
The patent implements dynamic control of RF front end circuits through separate control ports on RF integrated circuits. The processor can dynamically activate or deactivate specific RF front end circuits based on real-time processing needs. For example, when only first RF signal processing is required, the second RF front end circuit can be deactivated, reducing power consumption while maintaining the capability to activate it when needed.
3Measurement precision
If separate control ports are provided for each RF integrated circuit, then control precision is improved, but device complexity increases
Solution Approach 1:
The patent assigns dedicated control ports to specific RF integrated circuits and their corresponding RF front end circuits. The first control port on the first RF IC provides precise control for the first RF front end circuit, while the second control port on the second RF IC provides precise control for the second RF front end circuit. This localized control approach improves control precision by eliminating cross-interference while managing complexity through clear functional assignment.
