Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional interference evaluation methods are used, then calculation accuracy is maintained, but ease of operation deteriorates due to requiring expertise in radio wave propagation and apparatus specifications
Solution Approach 1:
The patent introduces an evaluation support apparatus that acts as an intermediary between the user and the complex interference calculation process. The apparatus automatically calculates interference power by retrieving station information from a database and processing it through predetermined calculation models, eliminating the need for users to manually input propagation loss values or configure complex parameters. This intermediary system handles the technical complexity while providing user-friendly operation.
Solution Approach 2:
The evaluation support apparatus performs self-service by automatically retrieving necessary station information (transmission power, frequency, location) from stored databases and independently executing the interference power calculation using predetermined propagation loss models. The system self-manages the complex calculation process without requiring user intervention in the computational details, allowing users to simply select stations and interpret results.
2Measurement precision
If detailed interference calculations are performed, then measurement precision is improved, but ease of operation worsens due to varying calculation methods for different subjects
Solution Approach 1:
The patent implements universality by creating a unified evaluation support apparatus that handles multiple types of interference calculations (ground station to ground station, satellite to ground station, ground station to satellite) using the same user interface and operation flow. The system automatically selects the appropriate calculation model based on the station types involved, providing precise measurements for different subjects through a single standardized process rather than requiring users to switch between different calculation methods.
Solution Approach 2:
The system manages parameter changes by automatically adjusting calculation parameters based on the types of stations involved. When users select different station combinations, the apparatus retrieves appropriate propagation loss models and calculation parameters from stored data without user intervention. This automatic parameter adaptation maintains measurement precision for various interference scenarios while keeping the operation simple for the user.
