Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If scenario-based tests are configured with detailed parameter values, then test coverage and reliability are improved, but configuration complexity and resource consumption increase
Solution Approach 1:
The patent segments scenario parameters into different types (numeric values, text values, value ranges) and organizes them in a structured configuration format. This segmentation allows complex test scenarios to be broken down into manageable parameter categories, reducing configuration complexity while maintaining comprehensive test coverage through systematic parameter variation.
2Reliability
If comprehensive parameter variation is performed to cover all scenario configurations, then test thoroughness is improved, but computing time and resource consumption increase
Solution Approach 1:
The patent performs preliminary configuration of scenario parameters with predefined values, value ranges, and validation rules before test execution. By preparing the parameter structure in advance and establishing clear configuration guidelines, the system reduces redundant validation steps during actual testing, thereby decreasing computing time while ensuring thorough test coverage through systematic parameter exploration.
3Adaptability or versatility
If manual configuration of scenario parameters is performed, then flexibility and adaptability are improved, but error rate and misconfiguration risk increase
Solution Approach 1:
The patent incorporates validation mechanisms that provide immediate feedback on configuration correctness. The system validates numeric values, text values, and value ranges against predefined constraints and provides error messages when misconfigurations are detected. This feedback mechanism maintains configuration flexibility while significantly reducing errors by guiding users through the configuration process and catching mistakes before test execution.
