Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual configuration methods are used to connect models in testing devices, then connection accuracy can be ensured, but configuration time and complexity increase significantly
Solution Approach 1:
The patent applies preliminary action by pre-defining compatibility rules and hierarchy structures for model connections. The system automatically determines compatible connections based on pre-established criteria, eliminating the need for manual configuration while ensuring accuracy. This is achieved through the automatic determination of compatible connections between hierarchy elements of source and destination models.
Solution Approach 2:
The system implements self-service by enabling automatic self-configuration of model connections. The testing device autonomously identifies compatible connections between models based on their hierarchy structures and compatibility rules, without requiring external manual intervention. This self-configuration capability resolves the contradiction by maintaining connection accuracy through automated rule-based determination.
2Measurement precision
If comprehensive model connections are established for complex simulation scenarios, then simulation accuracy improves, but device complexity and configuration effort increase
Solution Approach 1:
The patent applies segmentation by dividing models into hierarchy structures with multiple levels of abstraction. This hierarchical segmentation allows the system to manage complex simulation scenarios by breaking down large models into manageable sub-components, reducing configuration complexity while maintaining simulation accuracy through selective connection of hierarchy elements.
Solution Approach 2:
The system utilizes parameter changes by allowing flexible selection and configuration of hierarchy elements at different levels. Users can adjust the granularity and scope of model connections by selecting specific hierarchy elements, enabling the system to adapt to different simulation complexity requirements while maintaining accuracy through parameter-based control.
3Adaptability or versatility
If flexible selection of hierarchy elements is allowed, then adaptability to different simulation cases improves, but determination of compatible connections becomes more complex
Solution Approach 1:
The patent implements universality by creating a unified compatibility determination mechanism that works across all hierarchy elements and simulation cases. The system uses universal compatibility rules that can be applied regardless of the specific hierarchy elements selected, enabling flexible adaptation to different simulation scenarios while maintaining consistent and manageable connection determination processes.

AI summary
A method for connecting models of technical systems in a testing device equipped for control unit development having a connection of a first model of a first technical system to a second model of a second technical system. The first model and the second model include a model of a control unit, a model of a technical system to be controlled, or a model of an environment interacting with the control unit or with the technical system to be controlled. The first model has a first data interface and the second model has a second data interface. The method has the provision of a first model hierarchy structure and the provision of a second model hierarchy structure. The method has an automatic configuration of compatible connections so that the first model present in the testing device exchanges data with the second model present in the testing device through compatible connections.
