Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple antennas are configured for MIMO communication, then transmission efficiency and spectral efficiency are improved, but power consumption increases
Solution Approach 1:
The patent implements dynamic antenna selection where the system continuously monitors RF environment conditions and adaptively selects the optimal subset of antennas for transmission and reception. This dynamic adjustment allows the system to maintain high transmission efficiency when multiple antennas are beneficial while reducing power consumption by activating only the necessary number of antennas under varying environmental conditions
Solution Approach 2:
The system changes operational parameters by adjusting the number and configuration of active antennas based on RF environment assessments. By evaluating signal quality, interference levels, and channel conditions, the system dynamically modifies which antennas are activated, thereby optimizing the balance between transmission efficiency and power consumption
2Reliability
If more antennas are used to maximize bandwidth, then communication quality improves, but device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the antenna system into multiple independent antenna elements that can be individually selected and configured. This allows the system to use only the necessary number of antennas for a given communication task, reducing the effective complexity while maintaining the capability to achieve high communication quality when full MIMO configuration is beneficial
Solution Approach 2:
The system dynamically adjusts the antenna configuration based on RF environment conditions, selecting the optimal subset of antennas for each transmission or reception operation. This dynamic approach maintains communication quality by activating sufficient antennas while reducing device complexity by keeping other antennas in a low-power or inactive state
3Measurement precision
If representative antennas are used to determine RF environment, then antenna selection accuracy improves, but measurement precision requirements increase
Solution Approach 1:
The patent implements partial action by using only a representative subset of antennas to perform RF environment measurements and assessments. Instead of requiring all antennas to participate in environmental sensing, the system selects specific representative antennas that provide sufficient information for accurate antenna selection, thereby reducing the measurement burden while maintaining selection accuracy
