Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single antenna is used to monitor electromagnetic signals, then the device complexity is reduced, but the measurement precision deteriorates due to antenna orientation sensitivity
Solution Approach 1:
The system divides the single antenna function into multiple antennas with different orientations. Each antenna captures electromagnetic signals from different polarization angles, and the processor combines these segmented measurements to achieve orientation-independent characterization of computer system parameters.
Solution Approach 2:
The system transitions from a single-antenna (one-dimensional) measurement approach to a multi-antenna array (multi-dimensional) configuration. By adding spatial and orientational dimensions, the system captures signals from multiple polarization states, eliminating the limitation of orientation sensitivity.
2Measurement precision
If multiple antennas with non-parallel orientations are used, then the measurement precision improves by mitigating orientation sensitivity, but the device complexity increases
Solution Approach 1:
The multi-antenna system is designed to perform multiple functions: each antenna monitors electromagnetic signals from different orientations, and collectively they provide orientation-independent measurement capability. The processor integrates signals from all antennas to characterize computer system parameters regardless of antenna orientation relative to signal polarization.
3Ease of operation
If electromagnetic signals are analyzed using a single antenna, then the ease of operation is improved, but the reliability deteriorates due to signal loss from orientation mismatch
Solution Approach 1:
The processor analyzes electromagnetic signals from multiple antennas and uses this feedback to compensate for orientation effects. By comparing and combining signals from antennas with different orientations, the system reliably characterizes computer system parameters even when the optimal antenna orientation is unknown or changes.
