Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If devices for identifying beam characteristics are provided in locations corresponding to all possible directions, then measurement precision is improved, but device complexity and cost increase
Solution Approach 1:
The patent segments the beam characteristic measurement process into multiple time slots, where a single signal detector sequentially measures different beam directions at different times. This temporal segmentation replaces the need for spatial segmentation (multiple detectors for multiple directions simultaneously), thereby reducing device complexity while maintaining measurement precision
Solution Approach 2:
The patent implements periodic beam sweeping where the beam direction is changed in a systematic periodic manner across different time slots. The signal detector periodically measures beam characteristics at different directions following a predetermined sequence, enabling complete directional coverage with a single detector through time-based periodic measurement cycles
2Measurement precision
If inspection is performed on each antenna individually, then measurement precision is improved, but time consumption increases
Solution Approach 1:
The patent merges multiple antenna measurements into a single unified beam sweeping process. By measuring the composite beam characteristics formed by multiple antennas working together, the system can identify antenna faults through pattern recognition in the beam measurements, rather than requiring separate individual antenna inspections. This combining approach maintains detection accuracy while significantly reducing total measurement time
