Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If the terminal determines support capability based on multiple AI framework types and network model types, then the support capability information becomes comprehensive and accurate, but the capability report length increases and may exceed the maximum length of the capability indicator field

Engineering Contradiction:
Improvesupport capability information accuracyVSAvoidcapability report length
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The capability report is divided into two parts: a capability indicator field for common framework types shared by multiple network model types, and a capability indicator extension field for specific framework types of specific network model types. This segmentation allows comprehensive reporting while managing field length constraints.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent adds a new dimension (extension field) to the capability report structure, transitioning from a single flat field to a two-level hierarchical structure with base indicators and extension indicators, enabling expanded information capacity without increasing the base field length.

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

2Adaptability or versatility

If the terminal reports all supportable AI frameworks and network models, then the network device can fully utilize terminal capabilities, but the reporting overhead and processing complexity increase

Engineering Contradiction:
Improveframework compatibilityVSAvoidreporting overhead
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The capability information is segmented into common frameworks applicable to multiple network model types (reported in capability indicator field) and specific frameworks for each network model type (reported in extension fields), reducing redundant reporting.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The capability indicator field serves as a universal base that covers common AI frameworks supported across multiple network model types, while extension fields provide specific details, creating a multi-functional reporting structure.

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

3Reliability

If the capability report includes detailed information for each network model type, then the network device can make precise resource allocation decisions, but the capability indicator field exceeds maximum length

Engineering Contradiction:
Improveresource allocation accuracyVSAvoidfield length
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

Detailed capability information is segmented between the capability indicator field (for common frameworks) and capability indicator extension fields (for specific frameworks of each network model type), maintaining both detail and field length constraints.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The extension field acts as an intermediary that carries detailed specific capability information without burdening the main capability indicator field, allowing precise resource allocation while maintaining field length limits.

Inventive Principle:
Principle #24Intermediary (Mediator)
