Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If manual connection of control logic and simulation logic is performed, then flexibility in test setup is maintained, but time consumption and error rate increase significantly
Solution Approach 1:
The system performs preliminary actions by automatically specifying and connecting simulation logic to control logic before test execution begins. The logic connecting unit establishes these connections in advance based on logic connection information, eliminating the need for manual setup during the testing phase and significantly reducing test environment preparation time.
Solution Approach 2:
The system enables self-service by allowing the test device to automatically connect control logic and simulation logic without human intervention. The logic connecting unit autonomously performs the connection based on predefined logic connection information, making the system self-sufficient in setting up test environments and reducing dependency on manual operations.
2Reliability
If manual specification of simulation logic is performed, then connection accuracy can be verified, but human error in connecting wrong logic increases
Solution Approach 1:
The logic connecting unit acts as an intermediary between control logic and simulation logic, automatically establishing connections based on logic connection information. This intermediary component eliminates direct manual interaction, thereby preventing human errors in specifying and connecting the wrong logic while maintaining high connection accuracy.
Solution Approach 2:
The system incorporates feedback mechanisms where the logic connecting unit uses logic connection information to verify and establish correct connections between control logic and simulation logic. This feedback loop ensures that connections are made accurately according to predefined specifications, preventing erroneous connections.
3Reliability
If comprehensive testing of all control logic is performed, then test coverage is improved, but test complexity and resource requirements increase
Solution Approach 1:
The system segments the testing process by dividing control logic and simulation logic into distinct, manageable units that can be connected and tested individually. The logic connecting unit establishes connections between specific segments based on logic connection information, allowing comprehensive testing of all control logic while maintaining manageable system complexity through modular organization.
