Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a common synchronization configuration is used for all operation modes, then device complexity is reduced, but service reliability and latency requirements cannot be met for diverse services

Engineering Contradiction:
Improveservice reliabilityVSAvoidsynchronization configuration complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent segments the synchronization configuration into multiple operation modes (first operation mode and second operation mode), each with dedicated synchronization signal transmission configurations. This allows different services to be assigned to different operation modes with optimized parameters, achieving high reliability for diverse services without requiring a single complex universal configuration.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent implements dynamic switching between different operation modes based on service requirements. The base station can dynamically adjust the synchronization signal transmission configuration by switching operation modes, enabling the system to adapt to varying latency and reliability requirements of different services while maintaining manageable complexity through standardized mode definitions.

Inventive Principle:
Principle #15Dynamics

2Productivity

If synchronization configurations are optimized for specific services, then service performance is improved, but resource allocation efficiency decreases

Engineering Contradiction:
Improvecommunication efficiencyVSAvoidresource allocation efficiency
Core Design Contradiction:
ProductivityVSLoss of energy

Solution Approach 1:

The patent creates a universal operation mode framework where each operation mode can serve multiple services with similar requirements. By defining standardized operation modes that can be reused across different service types, the system achieves service-specific optimization without sacrificing overall resource allocation efficiency, as the same operation mode configuration can be applied to multiple services.

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

Solution Approach 2:

The patent optimizes communication efficiency by changing synchronization signal transmission parameters (such as transmission periodicity, time-frequency resources) based on operation modes. This allows the system to adjust parameters to match service requirements while maintaining efficient resource utilization through systematic parameter management rather than ad-hoc optimization.

Inventive Principle:
Principle #35Parameter changes

3Object-affected harmful factors

If different synchronization configurations are used for different operation modes, then interference management is improved, but device complexity increases

Engineering Contradiction:

Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The patent segments interference management into different operation modes, where each mode has dedicated synchronization signal transmission configurations designed to minimize interference for that specific mode. By confining interference management strategies to specific operation modes rather than attempting a universal approach, the system reduces overall complexity while effectively managing interference for each service type.

Inventive Principle:
Principle #1Segmentation
