Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If mathematical algorithms for spatial spectrum estimation are used to determine direction of arrival, then the lobe direction of the antenna can be adjusted, but the calculation process becomes complex and harsh conditions are required
Solution Approach 1:
The patent replaces complex mathematical algorithms (spatial spectrum estimation methods like MUSIC, ESPRIT) with a geometric approach using hyperbolic curves. Instead of performing complex spectral analysis calculations, the system uses the time difference of arrival to construct hyperbolic positioning curves, which simplifies the computational process while maintaining positioning accuracy. This substitution of calculation methodology directly addresses the contradiction between measurement precision and device complexity.
Solution Approach 2:
The patent introduces ultra-wide band modules as intermediary components that directly measure time difference of arrival and construct hyperbolic curves. These modules serve as intermediaries between the antenna system and the terminal, providing position information without requiring complex signal processing algorithms. The ultra-wide band modules simplify the overall system by handling the measurement and calculation tasks that would otherwise require complex mathematical algorithms.
2Reliability
If communication is established before adjusting the lobe of the antenna, then the antenna can be adjusted based on terminal position, but the adjustment process becomes time-consuming and resource-intensive
Solution Approach 1:
The patent implements preliminary action by determining terminal position information through ultra-wide band modules before establishing communication and before adjusting the antenna lobe. The system pre-acquires position data using the hyperbolic curve method, so that when communication is established, the antenna can be immediately adjusted to the optimal direction without waiting for communication setup or complex signal analysis. This preliminary positioning action eliminates the time delay between communication establishment and antenna adjustment.
Solution Approach 2:
The patent enables dynamic antenna adjustment by continuously tracking terminal position through the hyperbolic curve method and real-time ultra-wide band measurements. The system can dynamically redirect antenna lobes to follow moving terminals, optimizing resource distribution as terminals move within the coverage area. This dynamic capability allows the system to adapt quickly to changing terminal positions without being constrained by fixed communication protocols.
3Ease of manufacture
If a single adjustment method for the lobe is used, then the system is simple to implement, but the system lacks adaptability to different terminal positions and scenarios
Solution Approach 1:
The patent achieves universality by creating a positioning and adjustment system that works across multiple scenarios and terminal positions using the hyperbolic curve method. The ultra-wide band modules and hyperbolic curve construction approach provide a unified framework that adapts to different terminal locations, movement patterns, and network configurations. This universal method replaces multiple specialized adjustment algorithms with a single flexible approach that handles diverse scenarios effectively.
