Asset Administration Shell Templates for Reusable Digital Twin Models
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing asset administration shell information models are cumbersome to edit and reuse due to their window-based application nature, making it difficult to manage and connect reference models for digital twins in smart manufacturing.
Innovation Solution
A web-based service that provides sub-model and asset administration shell templates, allowing management of information models in stages based on the life cycle of an asset administration shell, with support for sharing and referencing policies, and uses user-friendly terms to minimize input items and enhance reuse.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a window-based application (APE) is used to create and manage asset administration shell information models, then the tool provides a dedicated UI for editing, but it becomes difficult to reuse sub-models and cumbersome to edit due to local environment constraints
Solution Approach 1:
The patent segments the asset administration shell information model into reusable sub-models that can be independently created, edited, and combined. This allows users to break down complex models into manageable components that can be reused across different contexts, resolving the contradiction by making editing more manageable while reducing overall complexity through modularity
Solution Approach 2:
The patent creates a web-based service that provides universal access to asset administration shell templates and sub-models through a standardized API interface. This multi-functional platform serves multiple purposes (creating, editing, reusing, and managing models) in a single accessible environment, improving ease of operation while reducing management complexity through centralized control
2Ease of operation
If the APE tool focuses on editing in the unit of asset administration shell, then it provides comprehensive editing capabilities, but it becomes very difficult to reuse sub-models
Solution Approach 1:
The patent enables segmentation of asset administration shell models into reusable sub-models that can be independently managed and combined. This segmentation allows comprehensive editing capabilities at the sub-model level while simultaneously enabling reuse across different asset administration shells, resolving the contradiction between editing capability and reusability
Solution Approach 2:
The patent provides pre-defined templates for asset administration shells and sub-models that can be reused across multiple projects. This preliminary preparation of standardized components enables both comprehensive editing when needed and efficient reuse when standard templates suffice, resolving the contradiction between editing capability and reusability
3Power
If a local environment application is used for creating asset administration shell information models, then it provides dedicated processing power, but it becomes difficult to share and reference models across different users and systems
Solution Approach 1:
The patent introduces a web-based service as an intermediary between local processing environments and shared model repositories. This intermediary provides centralized access to templates and sub-models through standardized APIs, enabling powerful local processing while simultaneously enabling widespread sharing and reference across different users and systems, resolving the contradiction between processing capability and shareability

AI summary
A method and a system for managing an asset administration shell life-cycle-based information model for a digital twin are provided. The method for managing an information model, according to an embodiment of the present invention, configures and manages (produces/modifies/deletes) an information model stepwise on the basis of an asset administration shell life cycle and supports a policy that can be shared/referenced. In addition, the present invention is a web-based service that can be used anywhere independently of a platform without installation, eliminates entry barriers of the asset administration shell through the use of user-friendly terms and standardized use patterns, and automatically produces some required attribute values according to a user and a life cycle so as to minimize input items. Therefore, businesses or operators considering digital twin application in the smart manufacturing field can conveniently create an asset administration shell information model and easily connect reference models of the digital twin.
