Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If dynamic beamforming utilizing active antenna system is introduced to enhance spectrum use efficiency, then spectrum use efficiency is improved, but protection of protection targets from radio wave interference becomes insufficient
Solution Approach 1:
The patent applies dynamic beamforming technology where the antenna pattern is changed over time based on detected communication devices. The control device determines beam patterns dynamically in response to detected devices, allowing the system to adapt to changing spectral conditions while maintaining interference protection. This dynamic adjustment enables efficient spectrum utilization without compromising protection targets.
Solution Approach 2:
The patent changes antenna pattern parameters (beam direction, width, shape) based on the detected communication devices and their transmission capabilities. By adjusting these parameters dynamically, the system optimizes spectrum access while ensuring that protection targets are not interfered with, thus resolving the contradiction between efficiency and protection.
2Object-affected harmful factors
If static antenna pattern is used in protection process, then protection of protection targets is maintained, but spectrum use efficiency is insufficient
Solution Approach 1:
The patent transitions from static to dynamic antenna patterns by detecting communication devices and adjusting beam patterns in real-time. This dynamic approach allows the system to maintain protection effectiveness while significantly improving spectrum use efficiency through adaptive beamforming that responds to actual spectral conditions.
Solution Approach 2:
The control device detects communication devices and uses this information as feedback to determine appropriate beam patterns. This feedback mechanism ensures that protection targets are protected while maximizing spectrum utilization, resolving the contradiction between protection and efficiency.
3Device complexity
If beam pattern is determined without detecting communication devices, then system complexity is reduced, but interference to protection targets cannot be controlled
Solution Approach 1:
The control device performs self-detection of communication devices and autonomously determines beam patterns based on the detected information. This self-service approach manages interference control without requiring complex external systems, maintaining simplicity while effectively protecting targets from interference.
