Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual configuration of test infrastructures with varying emulation fidelity levels is used, then testing can be performed with different fidelity requirements, but the process becomes time-consuming and inefficient
Solution Approach 1:
The system dynamically adjusts emulation fidelity levels during test execution based on real-time requirements. The test controller automatically selects between high-fidelity and low-fidelity TBEs depending on the specific test objectives, transforming the static manual configuration process into a dynamic adaptive system that optimizes testing efficiency while maintaining necessary accuracy.
Solution Approach 2:
The test system performs self-configuration by automatically selecting and configuring appropriate test bed elements based on test objectives without requiring manual intervention. The intelligent controller autonomously determines the required emulation fidelity levels and configures the test infrastructure accordingly, eliminating the time-consuming manual configuration process.
2Measurement precision
If high-fidelity test bed elements are used throughout the test infrastructure, then testing accuracy is improved, but resource allocation becomes inefficient and costs increase
Solution Approach 1:
The system applies different emulation fidelity levels to different parts of the test infrastructure based on local requirements. High-fidelity test bed elements are deployed only where testing accuracy is critical, while low-fidelity elements are used in areas where approximate behavior is sufficient. This localized quality approach optimizes resource allocation and reduces overall system costs while maintaining necessary testing accuracy.
Solution Approach 2:
The system changes the fidelity parameter of test bed elements dynamically based on test requirements. Instead of using a fixed high-fidelity configuration throughout, the intelligent controller adjusts the fidelity parameter of individual TBEs according to the specific test objectives, achieving optimal balance between accuracy and resource efficiency.
3Adaptability or versatility
If manual configuration processes are used, then flexibility in selecting test bed elements is maintained, but human error increases and configuration becomes complex
Solution Approach 1:
The test system performs self-configuration by automatically selecting appropriate test bed elements based on test objectives without requiring manual intervention. The intelligent controller autonomously determines the required emulation fidelity levels and configures the test infrastructure accordingly, eliminating human error while maintaining flexibility through programmatic decision-making.
Solution Approach 2:
The system incorporates feedback mechanisms where the test controller continuously monitors test requirements and adjusts the configuration of test bed elements accordingly. This closed-loop control ensures that the correct fidelity levels are applied to the appropriate test scenarios, maintaining both flexibility and reliability through automated feedback-driven configuration.
