Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If real-time analysis of large volumes of network diagnostic data is performed to identify coverage holes and capacity issues, then network coverage and capacity optimization is improved, but system complexity and processing requirements increase

Engineering Contradiction:
Improvenetwork coverage and capacity optimizationVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system segments the network analysis function into distributed network functions that can independently collect and analyze data from specific network domains. Each network function processes data locally before aggregating results, dividing the complex analysis task into manageable segments that reduce overall system complexity while maintaining comprehensive coverage analysis.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces an intermediary data collection and management layer that sits between raw network data sources and the analysis engine. This intermediary layer pre-processes, filters, and organizes diagnostic data before it reaches the coverage hole analysis functions, reducing the computational burden and simplifying the overall system architecture.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Measurement precision

If network functions collect and analyze capacity and coverage hole information continuously, then coverage hole detection accuracy is improved, but data processing load and resource consumption increase

Engineering Contradiction:
Improvecoverage hole detection accuracyVSAvoiddata processing load
Core Design Contradiction:
Measurement precisionVSUse of energy by moving object

Solution Approach 1:

The system implements periodic data collection and analysis cycles rather than continuous processing. Network functions collect diagnostic data at defined intervals and perform coverage hole analysis periodically, maintaining detection accuracy while significantly reducing continuous data processing load and resource consumption during idle periods.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The patent applies preliminary filtering and pre-processing of network diagnostic data before full analysis. Network functions identify and flag potential coverage holes based on threshold criteria during data collection, then perform detailed analysis only on flagged cases, reducing overall processing load while maintaining detection accuracy for actual coverage holes.

Inventive Principle:
Principle #10Preliminary action

3Reliability

If network functions implement policy-based modifications to address coverage holes, then network service quality is improved, but control complexity and policy management overhead increase

Engineering Contradiction:
Improvenetwork service qualityVSAvoidpolicy management overhead
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system addresses coverage holes by modifying network parameters through policies, such as adjusting transmission power levels, antenna tilt angles, or resource allocation parameters. These parameter changes are managed through standardized policy templates that simplify complexity while achieving service quality improvements in affected areas.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent implements feedback mechanisms where network functions continuously monitor the effects of policy modifications on coverage and capacity. This feedback loop enables automatic adjustment and optimization of policies, reducing manual management overhead while maintaining high service quality through data-driven decision making.

Inventive Principle:
Principle #23Feedback
