Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a centralized core network is used, then network elements can process a large quantity of users, but the network has a single point failure risk and cannot meet personalized user requirements

Engineering Contradiction:
Improvepersonalized user requirementsVSAvoidsingle point failure risk
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent segments the centralized core network into distributed digital reflections (DRs) deployed at multiple edge locations. Each DR independently serves users in its local area, eliminating the single point of failure risk while maintaining the ability to handle large numbers of users through distributed processing capacity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces a hierarchical architecture with two dimensions: centralized policy control (for coordination) and distributed user plane functions (for data processing). This dimensional separation allows personalized services through local DRs while maintaining overall network reliability through redundancy.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Ease of operation

If a digital reflection is deployed on edge cloud for each terminal device, then user centric network architecture is achieved, but communication delay increases due to querying mapping system for addresses

Engineering Contradiction:
Improveuser centric network architectureVSAvoidcommunication delay
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The patent implements preliminary action by having the first digital reflection store the terminal device's binding information (including address mapping) in advance. When data needs to be transmitted, the first DR directly uses the pre-stored binding information to forward data to the second DR, eliminating the need for real-time mapping system queries and reducing communication delay.

Inventive Principle:
Principle #10Preliminary action

3Device complexity

If centralized core network elements are used, then network management is simplified, but packet header overheads increase and communication efficiency decreases

Engineering Contradiction:
Improvenetwork management complexityVSAvoidcommunication efficiency
Core Design Contradiction:
Device complexityVSProductivity

Solution Approach 1:

The patent extracts the data processing functions from the centralized core network and places them at the edge through distributed digital reflections. This extraction reduces the amount of data that needs to be routed through centralized elements, thereby reducing packet header overheads and improving communication efficiency while maintaining manageable network complexity through automated DR coordination.

Inventive Principle:
Principle #2Taking out (Extraction)
