Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If users physically visit testing facilities to configure and execute tests, then tests can be performed with available test components, but the process becomes time-consuming and geographically restricted
Solution Approach 1:
The patent creates virtual copies of test environments and test components that can be accessed remotely over a network. Users can configure and execute tests on virtual test benches without physically visiting the facility, thereby reducing time loss while maintaining test reliability through accurate virtual representations of the physical test environment.
Solution Approach 2:
The patent introduces a network communication system as an intermediary between users and test facilities. This intermediary enables remote access to test components and environments, eliminating the need for physical presence while ensuring reliable test execution through standardized communication protocols and interface abstractions.
2Adaptability or versatility
If generic test components are provided at testing facilities, then the facility can serve multiple users, but the test components cannot fulfill complex or new test requirements
Solution Approach 1:
The patent implements dynamic test environment configuration where test packages and test bench settings can be adjusted and customized based on specific test requirements. Users can modify test parameters, select different test components, and adapt the test environment dynamically without requiring physical reconfiguration, thereby enhancing versatility while managing complexity through software-based control.
Solution Approach 2:
The patent divides the test system into modular, independently configurable components that can be selectively assembled into different test packages. This segmentation allows users to combine specific test components and configurations to meet complex or new test requirements while maintaining overall system manageability through standardized interfaces and modular architecture.
3Ease of operation
If test configuration is performed manually by users, then users can customize tests, but errors are easily introduced and corrections are difficult
Solution Approach 1:
The patent implements automated validation mechanisms that provide immediate feedback on test configuration errors. The system checks configuration files, validates test package parameters, and notifies users of any issues before test execution, thereby maintaining ease of manual configuration while significantly improving configuration accuracy through automated error detection and correction guidance.
4Productivity
If end-to-end test processes are managed manually by different users on different systems, then each user can control their portion, but the process becomes inefficient and error-prone
Solution Approach 1:
The patent merges multiple manual test management processes into a single integrated automated system that handles the entire end-to-end test workflow. The system consolidates test package generation, environment configuration, test execution, and result collection into one unified process, thereby improving productivity by eliminating manual handoffs and reducing errors, while managing complexity through centralized automated control and standardized interfaces.
