Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing digital twin technologies are limited to single systems or processes, leading to increased complexity and management challenges when scaling to large-scale applications such as city or national levels due to the exponential rise in the number of objects and target models.
Innovation Solution
A digital twin federation apparatus and method that extracts and synchronizes data from multiple digital twin systems, aligning them in the same time slot and unit, and delivers the linked data to an application service layer, while managing and validating the systems to reduce complexity and cost.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If digital twin technology is scaled to large-scale applications at city or national levels, then the scope and impact of the digital twin increases, but the complexity of implementation and management increases exponentially
Solution Approach 1:
The patent segments the large-scale digital twin system into multiple independent digital twin systems, each managing a specific object or subsystem. These segmented systems can be developed, managed, and scaled independently, preventing exponential complexity growth while maintaining the ability to cover city or national levels through federation of multiple units.
2Quantity of substance
If the number of objects and target models in the digital twin increases for large-scale applications, then the coverage and capability of the digital twin improves, but the complexity of construction and management increases exponentially
Solution Approach 1:
The system divides the large number of objects into multiple digital twin systems, each handling a manageable subset. This segmentation allows the quantity of objects to increase linearly across systems rather than exponentially within a single system, reducing construction and management complexity.
Solution Approach 2:
The patent implements a universal data exchange standard that enables different digital twin systems to communicate and federate their data. This universal interface allows the system to handle an increasing number of objects through standardized protocols, preventing complexity from scaling exponentially with the number of objects.
3Adaptability or versatility
If multiple digital twin systems are integrated to form a large-scale digital twin, then the scope of application expands, but the data synchronization and linking complexity increases
Solution Approach 1:
The patent establishes a universal data exchange standard that enables seamless integration of multiple digital twin systems. This standardization provides common data formats, protocols, and interfaces, significantly reducing the complexity of data synchronization and linking between systems while expanding the federated digital twin's scope.
