Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If sensor placement is constrained by restricted domain or accessibility, then sensor mounting options are limited, but sensor data quality deteriorates
Solution Approach 1:
The patent applies preliminary action by creating a virtual sensor model and performing simulations before actual sensor installation. The optimization algorithm determines the optimal sensor position in advance using the physical simulation model, allowing planners to identify the best mounting location without being constrained by accessibility issues during actual installation. This pre-planning approach enables selection of theoretically optimal positions that may be harder to access but provide superior measurement quality.
2Measurement precision
If sensor position is not optimized, then installation is simpler, but monitoring accuracy deteriorates
Solution Approach 1:
The patent applies copying by creating a virtual copy of the sensor (virtual sensor model) and the technical system (physical simulation model). This virtual copy allows optimization of sensor position through simulation without affecting the actual physical installation process. The optimization algorithm operates on the virtual model to determine optimal positioning, which then guides the actual sensor placement. This copying approach adds computational complexity but keeps the physical installation process simple.
3Reliability
If virtual sensor optimization is performed, then response signal intensity is improved, but computational requirements increase
Solution Approach 1:
The patent applies parameter changes by optimizing the sensor position parameters (coordinates, orientation) to maximize response signal intensity. The optimization algorithm adjusts these positional parameters within the virtual simulation environment to find configurations that yield the strongest and most informative sensor responses. This parameter optimization improves signal quality while the computational energy is consumed only in the virtual simulation phase, not during actual sensor operation.
