Engineering Contradiction Analysis
1Productivity
If existing antenna design computer programs calculate structural parameters independently without considering correlations, then each parameter can be calculated separately, but calculation time increases and efficiency decreases
Solution Approach 1:
The patent transforms the calculation approach by changing from independent parameter calculation to correlated parameter calculation. It identifies correlations between structural parameters (e.g., antenna element dimensions, spacing, feed point positions) and calculates them together using relational expressions, thereby improving calculation efficiency and reducing time loss.
2Productivity
If the antenna design program calculates all structural parameters independently, then the calculation process is simple, but it fails to utilize parameter correlations leading to increased calculation time
Solution Approach 1:
The patent introduces relational expressions that define correlations between structural parameters. Instead of calculating each parameter independently, the system establishes mathematical relationships between correlated parameters (e.g., relating antenna element length to width, or spacing between elements), thereby accelerating calculation while managing complexity through structured relationships.
Solution Approach 2:
The patent uses a reference antenna model with known optimal parameters and correlations. It copies the correlation structure from the reference model and applies it to the target antenna design, allowing the system to leverage pre-established parameter relationships rather than recalculating all correlations from scratch.
3Loss of time
If the program does not consider correlated parameters, then the calculation method is straightforward, but it results in inefficient use of computational resources and increased calculation time
Solution Approach 1:
The patent systematically identifies and quantifies correlations between structural parameters by analyzing their interdependencies. It transforms the calculation process from treating parameters as independent variables to treating them as correlated variables with defined relationships, thereby reducing computational time while incorporating the necessary complexity of parameter interactions.
