Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If repeated calculation and testing is performed to determine load coil value and location, then the accuracy of signal reception is improved, but the time and cost required increases significantly
Solution Approach 1:
The patent applies preliminary action by pre-calculating theoretical load coil values using measurement data obtained from the antenna system before actual installation and testing. This allows the testing process to start with pre-determined candidate values rather than requiring exhaustive repeated calculations and measurements, significantly reducing the time and resources needed while maintaining accuracy.
2Manufacturing precision
If multiple load coil values are tested at various locations, then the optimal load coil configuration is identified, but the process becomes tedious and costly
Solution Approach 1:
The patent applies segmentation by dividing the load coil selection process into distinct stages: obtaining measurement data from the antenna system, calculating theoretical load coil values based on that data, and then testing only those calculated values at predetermined locations. This segmented approach replaces the need for exhaustive testing of multiple random configurations, making the process less tedious and costly while achieving precise load coil configuration.
3Measurement precision
If conventional measuring equipment is used for parameter measurement, then the measurement capability is sufficient, but the overall process efficiency decreases
Solution Approach 1:
The patent applies mechanics substitution by replacing the conventional mechanical/manual process of repeated measurement and calculation with an automated computational approach. The system uses obtained measurement data to automatically calculate theoretical load coil values, eliminating the need for manual repeated measurements and calculations, thereby significantly improving process efficiency while maintaining measurement precision.
