Solution Overview

Problem

Existing digital twin systems face challenges in efficiently searching through large numbers of digital twins, leading to increased search times due to the complexity of relationships between digital twins.

Innovation Solution

The method involves generating an aggregated digital twin, referred to as a cototwin, by integrating multiple digital twins that satisfy specific conditions. This cototwin reduces the number of digital twins and relationships to be searched, thereby shortening search times.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If multiple digital twins are stored individually in the database, then the information completeness is improved, but the search time increases due to the large number of digital twins and complex relationships

Engineering Contradiction:

Improveinformation completenessVSAvoidsearch time

Core Design Contradiction:

Loss of informationVSLoss of time

Solution Approach 1:

The patent applies merging by combining multiple individual digital twins into a single aggregated digital twin (cototwin) that represents a group of digital twins sharing common characteristics. This aggregation reduces the total number of digital twin entities in the database while preserving the essential information of the constituent digital twins through grouped representation, thereby maintaining information completeness while significantly reducing search time.

Inventive Principle:

Principle #5Merging (Combining)

2Loss of time

If digital twins are aggregated into a single cototwin, then the search time is reduced, but the detail information of individual digital twins may be lost

Engineering Contradiction:

Improvesearch timeVSAvoiddetail information

Core Design Contradiction:

Loss of timeVSLoss of information

Solution Approach 1:

The patent applies segmentation by organizing digital twins into hierarchical groups where a cototwin represents an aggregated view of multiple individual digital twins. The system maintains the ability to segment and access individual digital twins within the aggregated group when detailed information is needed, thus balancing the reduction of search time through aggregation with the preservation of access to detailed information when required.

Inventive Principle:

Principle #1Segmentation

3Adaptability or versatility

If the number of digital twins is increased to cover more scenarios, then the system coverage is improved, but the device complexity increases

Engineering Contradiction:

Improvesystem coverageVSAvoidsystem complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies universality by creating cototwins that can represent multiple individual digital twins with similar characteristics. This aggregated representation serves multiple functions: it reduces system complexity by decreasing the number of entities to manage, while simultaneously maintaining system coverage by preserving the ability to represent various scenarios through different cototwin groupings. The cototwin structure enables one aggregated entity to fulfill the role of multiple individual digital twins.

Inventive Principle:

Principle #6Universality (Multi-functionality)
