Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If traditional beamforming techniques are used to direct radio frequency signals, then signal directionality is improved, but broad coverage and uniform signal strength across large regions deteriorate
Solution Approach 1:
The patent introduces a vertical dimension to beamforming by utilizing a reflective surface positioned above the transmitting antenna array. This creates a three-dimensional beamforming structure where signals can be reflected at different angles to cover both horizontal and vertical spatial dimensions, thereby achieving broad coverage while maintaining signal directionality through the addition of the reflective surface dimension
Solution Approach 2:
The reflective surface acts as an intermediary element between the transmitting antenna array and the target coverage area. By introducing this intermediate reflective surface, the system can achieve broad coverage and uniform signal distribution without compromising signal directionality, as the reflective surface mediates the signal propagation path to reach multiple target areas effectively
2Measurement precision
If traditional beamforming techniques are used to direct radio frequency signals, then signal focus is improved, but uniform signal strength across large regions deteriorates
Solution Approach 1:
The patent segments the beamforming function into two independent parts: the transmitting antenna array that provides signal focus and directionality, and the reflective surface that provides broad coverage and signal distribution. This segmentation allows each component to optimize its specific function without compromising the other, achieving both signal focus and uniform signal strength across large regions
Solution Approach 2:
By adding the reflective surface dimension, the system creates multiple signal paths (direct and reflected) that can be independently controlled. This dimensional addition enables the system to maintain signal focus through the antenna array while achieving uniform signal distribution across the coverage area through the reflected signal paths
