Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If digital twin services are supported in the communication network, then service flexibility and network intelligence are improved, but system complexity and difficulty of implementation increase due to lack of clear building methods

Engineering Contradiction:

Improvedigital twin service supportVSAvoidsystem implementation complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments the digital twin subsystem into distinct functional components: DT-UE for terminal functions, DT-AF for data network services, DT-CN for core network services, and DT-RAN for radio access network services. This segmentation provides a clear architectural framework that reduces implementation complexity while maintaining service flexibility.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces a network function as an intermediary that manages the interaction between the digital twin subsystem and the physical communication network. This intermediary handles the complexity of synchronization and isolation mechanisms, allowing digital twin services to be supported without directly complicating the core network infrastructure.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Quantity of substance

If air interface and terminal reuse are implemented in digital twin network, then resource efficiency is improved, but interference and service isolation difficulties increase

Engineering Contradiction:

Improveresource reuse efficiencyVSAvoidinterference between digital and physical networks

Core Design Contradiction:

Quantity of substanceVSObject-affected harmful factors

Solution Approach 1:

The patent employs the network function as an intermediary that manages resource allocation and isolation between digital twin and physical network entities. This intermediary ensures that reused air interfaces and terminals operate without harmful interference by coordinating their usage and maintaining proper service isolation.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent applies different quality characteristics to different parts of the system: the digital twin subsystem operates with virtualized resources while the physical network maintains its native characteristics. This local differentiation allows resource reuse at the interface level while maintaining isolation at the service level, preventing interference.

Inventive Principle:

Principle #3Local quality

3Extent of automation

If digital twin subsystem is integrated into existing network architecture, then network intelligence is improved, but synchronization and isolation control difficulty increase

Engineering Contradiction:

Improvenetwork intelligence levelVSAvoidsynchronization and isolation control

Core Design Contradiction:

Extent of automationVSDevice complexity

Solution Approach 1:

The network function serves as a mediator that handles the complex tasks of synchronization and isolation control between the digital twin subsystem and the physical network. By offloading these control functions to the intermediary, the patent maintains network intelligence while reducing the direct complexity of synchronization and isolation management.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent implements feedback mechanisms where the network function continuously monitors the state of both digital twin and physical network entities, adjusting resource allocation and isolation parameters in real-time. This feedback control enables automatic synchronization and isolation management, reducing manual control complexity while maintaining high network intelligence.

Inventive Principle:
