Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If traditional methods are used to identify no-coverage areas, then the process is simple, but the identification accuracy and efficiency are insufficient

Engineering Contradiction:

Improveno-coverage area identification accuracyVSAvoiddata processing system complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The patent segments the identification process into multiple data sources (drive test data, geographic data, network data) and processes them separately before integration. This segmentation allows each data type to be optimized independently, improving overall identification accuracy without overwhelming system complexity

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent merges multiple data sources (drive test data, geographic data, network data) into a unified analysis framework. This combination enables cross-validation and comprehensive coverage analysis, significantly improving identification accuracy while the modular architecture manages the complexity of integrating diverse data types

Inventive Principle:

Principle #5Merging (Combining)

2Reliability

If comprehensive data analysis is performed to identify no-coverage areas, then the coverage optimization is improved, but the processing time and computational resources increase

Engineering Contradiction:

Improvecoverage optimization qualityVSAvoidarea identification processing time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent performs preliminary data validation, cleaning, and preprocessing before the main analysis. Drive test data, geographic data, and network data are prepared in advance with quality checks, reducing the computational burden during the actual no-coverage area identification and accelerating the overall process

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent replaces traditional mechanical/sequential data processing methods with automated computational algorithms. The system uses algorithmic approaches to analyze multiple data sources simultaneously, reducing manual intervention and processing time while maintaining high reliability in coverage optimization identification

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
