Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If network functions are dynamically managed in highly heterogeneous environments to support diverse applications, then adaptability and resource efficiency improve, but network stability and reliability deteriorate due to potential instabilities from third-party code and diverse requirements

Engineering Contradiction:
ImproveadaptabilityVSAvoidnetwork stability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The network is segmented into multiple sub-networks (network slices) that are logically separated but physically coexist on shared infrastructure. Each slice can be independently managed, configured, and isolated, allowing diverse applications to run in separate environments with different requirements while preventing failures in one slice from affecting others. This segmentation enables both high adaptability for diverse applications and maintained stability through isolation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent implements nested virtualization where virtual network functions are embedded within sub-networks, which themselves are embedded within the broader 5G network infrastructure. This nested structure allows multiple levels of abstraction and isolation, enabling third-party code and diverse applications to operate in innermost layers while outer layers maintain overall network stability and control.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Productivity

If network resources are dynamically allocated to meet diverse application requirements, then resource efficiency improves, but network complexity increases due to heterogeneous environments and multiple sub-networks

Engineering Contradiction:
Improveresource efficiencyVSAvoidnetwork complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent creates universal network functions and management mechanisms that can operate across all sub-networks and heterogeneous environments. The network slice management apparatus and resource allocation mechanisms are designed to be platform-agnostic and application-agnostic, providing unified control planes that simplify complexity while enabling efficient resource allocation across diverse technologies and applications.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The network implements dynamic resource allocation where network functions and resources can be flexibly assigned, scaled, and reconfigured based on real-time requirements. Virtual network functions can be dynamically instantiated, migrated, and terminated across different sub-networks, allowing efficient resource utilization while the underlying infrastructure maintains standardized interfaces that prevent complexity from proliferating.

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If third-party code and external applications are integrated into the network, then adaptability and functionality improve, but security and reliability worsen due to potential instabilities and lack of control

Engineering Contradiction:
ImprovefunctionalityVSAvoidnetwork reliability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent extracts third-party code and external applications into isolated sub-networks or network slices that are separated from the core network infrastructure. These external elements are 'taken out' of the main network control plane and placed in dedicated containers or virtualized environments where they can operate with limited privileges and restricted access, maintaining functionality while preventing instabilities from propagating to the core network.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent introduces intermediary management layers and abstraction interfaces between third-party code and the core network. These intermediaries act as mediators that translate external application requirements into standardized network operations, enforce security policies, and provide controlled access to network resources, thereby maintaining reliability while enabling diverse functionality.

Inventive Principle:
Principle #24Intermediary (Mediator)
