Engineering Contradiction Analysis
1Measurement precision
If a rotating antenna array system is implemented to determine device location with high accuracy, then measurement precision and reliability are improved, but device complexity increases
Solution Approach 1:
The system divides the location determination task into multiple measurement phases, with each antenna taking measurements at different stopping points around a circular path. By segmenting the measurement process across multiple antennas and positions, the system achieves high precision through cumulative averaging while keeping individual antenna designs relatively simple.
Solution Approach 2:
The antenna array rotates periodically around a circular path, stopping at predetermined points to collect location information. This periodic rotation and stopping pattern allows the system to gather comprehensive spatial data from multiple angles, improving measurement precision through repeated measurements that are then averaged to reduce error.
2Measurement precision
If multiple stopping points are used to calculate cumulative average of center points, then measurement precision is improved, but loss of time increases
Solution Approach 1:
The system pre-determines the circular rotation path and stopping points before actual measurement begins. By establishing the measurement geometry in advance, the system optimizes the measurement process to achieve high precision without unnecessary time consumption, as the stopping points are strategically positioned to maximize information gain.
Solution Approach 2:
The antenna array maintains continuous rotation through the predetermined circular path, collecting location information continuously at multiple stopping points. This continuous measurement approach, combined with real-time processing of the cumulative average, ensures high precision location determination while minimizing idle time between measurements.
