Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If digital twins are developed and used in different domains independently, then each domain can optimize its specific functions, but interoperability and federation between domains become difficult
Solution Approach 1:
The patent implements a universal metadata schema that can represent digital twins across multiple domains (manufacturing, healthcare, energy, etc.). This schema includes domain-agnostic elements such as identification, state, behavior, and relationship metadata, allowing digital twins from different domains to be federated and interoperated while maintaining their domain-specific characteristics through optional domain extensions.
Solution Approach 2:
The patent introduces a metadata repository and federation management system as an intermediary layer between domain-specific digital twins. This intermediary standardizes the representation and interaction protocols, enabling seamless federation across domains without requiring changes to the domain-specific digital twin implementations themselves.
2Adaptability or versatility
If multiple single digital twins are federated to solve complex multi-domain problems, then new services and capabilities are enabled, but system complexity increases
Solution Approach 1:
The patent segments the federation system into distinct functional modules: metadata repository for standardized data storage, federation management for orchestration, synchronization modules for data consistency, and simulation engines for analysis. This modular architecture reduces overall system complexity by allowing each component to be developed, maintained, and scaled independently.
Solution Approach 2:
The patent employs standardized metadata parameters and schemas that transform heterogeneous domain-specific data into a unified representation. By changing the parameter structure to a standardized format, the system can federate digital twins across domains without being overwhelmed by data heterogeneity, thus managing complexity while enabling new services.
3Adaptability or versatility
If digital twins from different domains are federated, then complex multi-domain problems can be solved, but data synchronization and consistency become challenging
Solution Approach 1:
The patent implements bidirectional synchronization mechanisms with feedback loops that continuously monitor and adjust data consistency across federated digital twins. When changes occur in one domain, the system detects these changes and propagates them to related digital twins in other domains, maintaining temporal and spatial consistency through automated feedback-driven updates.
Solution Approach 2:
The patent establishes preliminary synchronization protocols and metadata schemas before federating digital twins from different domains. By pre-defining data representation standards, relationship models, and synchronization rules in advance, the system prevents data inconsistency issues rather than having to resolve them after federation occurs, thus maintaining data integrity across domains.

AI summary
A digital twin federation system for interoperability and federation between digital twins and an operating method thereof are provided. The digital twin federation system includes single digital twins to be federated, a metadata repository that stores metadata on the single digital twins and a federated digital twin, a federated digital twin generated by federating the single digital twins, and a management device that searches for a single digital twin providing a specific service among the single digital twins from the metadata repository through a search function to determine the single digital twin to be a digital twin for the federated digital twin, generates the federated digital twin where the single digital twins are federated, and generates a tool for providing a service of the federated digital twin, thereby expanding existing services and provide new services by federating digital twins, and easily solving problems involving domains through simulation and visualization.
