Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If edge digital twin application objects directly interact with cloud digital twin systems, then information interaction and data collection are improved, but device complexity and interface requirements increase
Solution Approach 1:
The patent introduces an edge terminal as an intermediary device between edge digital twin application objects and cloud digital twin systems. This edge terminal provides standardized information interaction interfaces and protocols, enabling state data collection and decision information execution without requiring complex direct interfaces between application objects and cloud systems. The edge terminal acts as a mediator that simplifies the interaction complexity while maintaining full information interaction capabilities.
2Adaptability or versatility
If multiple data interfaces and protocols are supported for different application objects, then adaptability is improved, but device complexity increases
Solution Approach 1:
The edge terminal is designed with multi-functional capabilities to support multiple data interfaces and protocols simultaneously. It can adapt to different application objects (single or multiple) by providing standardized interaction interfaces while maintaining compatibility with various communication protocols. This universal design enables the edge terminal to handle diverse application objects without proportionally increasing system complexity, as the terminal consolidates multiple interface functions in a single device.
3Extent of automation
If decision information is transmitted through cloud digital twin system, then centralization is improved, but response time and reliability deteriorate in offline conditions
Solution Approach 1:
The patent segments the control functionality by dividing decision-making capabilities between the cloud digital twin system and the edge terminal. The cloud system provides centralized decision information generation, while the edge terminal incorporates local control modules that can independently execute decisions even when offline. This segmentation ensures that centralized automation is maintained when connected, while reliability is preserved during offline operations through local decision execution capabilities.
4Ease of operation
If standardized information interaction interfaces are provided, then ease of operation is improved, but adaptability to different protocols may be reduced
Solution Approach 1:
The edge terminal serves as a standardized interface mediator that provides uniform interaction protocols to application objects while internally supporting multiple communication protocols. This allows application objects to interact through standardized interfaces without losing adaptability to different protocols, as the edge terminal handles protocol conversion and adaptation transparently. The standardized interface simplifies operation while the internal multi-protocol support maintains versatility.
