Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If radio wave refraction plates are installed to refract radio waves, then received power is improved, but phase interference occurs due to improper positioning
Solution Approach 1:
The patent calculates and determines the optimal installation positions of refraction plates before actual deployment. By pre-calculating positions based on Fresnel zone analysis and geometric relationships between base station and terminal, the system ensures that plates are placed where they will refract radio waves constructively without causing phase interference, thus resolving the contradiction between improving received power and avoiding reliability issues.
Solution Approach 2:
The patent applies different refraction characteristics to different regions by positioning specific refraction plates at specific locations along the propagation path. Each plate's position is optimized to address local phase and amplitude characteristics of the radio wave field, ensuring that refraction occurs at optimal points to maximize received power while maintaining phase coherence.
2Power
If multiple refraction plates are installed to enhance signal, then received power increases, but device complexity increases
Solution Approach 1:
The patent determines the minimum necessary number of refraction plates required to achieve the desired received power improvement. Rather than deploying excessive plates, the system calculates the optimal subset of plates and their positions, implementing only what is necessary to achieve constructive interference and maximize signal strength, thus balancing performance improvement with system simplicity.
3Power
If refraction plates are positioned to maximize odd-order Fresnel zone area, then received power increases, but installation precision requirements increase
Solution Approach 1:
The patent provides explicit mathematical formulas and calculation methods for determining refraction plate positions based on Fresnel zone analysis. By pre-calculating the geometric center positions and optimal installation coordinates using these formulas, the system reduces on-site measurement and positioning requirements, as the theoretical positions can be computed in advance with standard parameters.
Solution Approach 2:
The patent analyzes how received power varies with refraction plate position parameters and identifies optimal parameter ranges. By understanding the relationship between position parameters and received power, the system can tolerate certain variations in installation precision while still achieving significant power improvement, thus reducing the stringency of precision requirements.
