Solution Overview
Problem
Existing digital twin methods require significant system resources and increase operating load, making them unsuitable for industrial applications due to high production costs.
Innovation Solution

Engineering Contradiction Analysis
1Adaptability or versatility
If multiple separate models and scenarios are built for different physical entities, then the digital twin can comprehensively represent various objects, but the system resource occupation and operating load increase significantly
Solution Approach 1:
The patent merges multiple separate models for different physical entities into a single unified model. The unified model contains multiple entity models that represent different physical entities (target object and sub-target objects), allowing comprehensive representation while reducing system resource occupation by eliminating the need for separate model files and reducing memory overhead.
Solution Approach 2:
The unified model serves multiple functions simultaneously - it can represent the target object, its sub-target objects, and their spatial relationships all within a single model structure. This multi-functionality allows the system to handle various digital twin scenarios without requiring separate specialized models for each entity type.
2Measurement precision
If detailed spatial attributes and coordinate systems are established for each entity, then the positional relationships between physical entities can be accurately described, but the model complexity and data processing requirements increase
Solution Approach 1:
The patent segments the spatial description into hierarchical levels - the unified model contains a first coordinate system for the target object, while sub-target objects have their own second coordinate systems. This segmentation allows precise local measurements for each entity while maintaining overall spatial coherence through the hierarchical structure, reducing the complexity of managing all coordinate transformations at once.
Solution Approach 2:
The patent implements a nested coordinate system structure where the second coordinate system of sub-target objects is nested within the first coordinate system of the target object. This nesting allows accurate representation of positional relationships at multiple scales - sub-target objects can be precisely positioned relative to the target object while the target object itself can be positioned in the broader environment.
3Adaptability or versatility
If a parent-child relationship structure is implemented between entity models, then the hierarchical structure of physical entities is better represented, but the association management complexity increases
Solution Approach 1:
The patent implements dynamic parent-child relationships where sub-target objects can be flexibly associated with or disassociated from the target object based on their spatial positions. When a sub-target object moves outside the spatial range of the target object, the system automatically adjusts the association status. This dynamic management reduces the complexity of manual association management while maintaining accurate hierarchical representation.

AI summary
The present disclosure relates to the technical field of digital twinning, and discloses a twinning method for a current state of a target object, a subscription method and a system. The twinning method comprises: for a currently existing target object, and at least one sub-target object forming the target object, respectively establishing a target object model and at least one sub-target object model; and establishing an association relationship between the target object model and the at least one sub-target object model. Thus, the effect of simplifying existing twinning methods for target objects can be achieved.
