Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual testing methods are used for HMI applications, then testing can be performed with human expertise and consistency, but the process becomes expensive, time-consuming, and not scalable
Solution Approach 1:
The system enables self-service testing through automated test case generation and execution. The testing framework automatically generates test cases from interface definitions and executes them without requiring skilled human testers, making the testing process independent and self-sufficient while maintaining consistency and scalability
Solution Approach 2:
The patent replaces manual mechanical testing processes with an automated computer-based testing system. The testing framework uses automated scripts and algorithms to generate and execute test cases, substituting human operators with mechanical/automated systems that provide both consistency and scalability
2Ease of manufacture
If model-based testing is used for HMI applications, then testing can be structured with test-oriented models, but the process becomes time-consuming and delays deployment
Solution Approach 1:
The system performs preliminary action by pre-defining interface specifications and test criteria in a standardized format. Test cases are automatically generated from these pre-defined interface definitions, eliminating the time-consuming process of creating test models from scratch and accelerating the deployment process while maintaining structured testing
Solution Approach 2:
The patent changes parameters by transforming the testing approach from model-based (requiring complex test models) to interface-based (using standardized interface definitions). This parameter change in the testing methodology reduces complexity and time requirements while maintaining systematic testing structure
3Adaptability or versatility
If frequent updates are made to HMI applications to maintain product differentiation, then user experience improves, but test coverage becomes insufficient and validation becomes challenging
Solution Approach 1:
The system ensures continuity of useful action by implementing automated testing that can continuously validate HMI applications across frequent updates. The testing framework automatically generates and executes test cases for each update, maintaining continuous test coverage without interruption despite frequent changes in the application
Solution Approach 2:
The patent implements feedback mechanisms where test results automatically inform subsequent testing iterations. The system provides continuous feedback on test coverage and validation status, enabling rapid identification of issues in frequently updated applications and ensuring maintained test coverage through iterative improvement
