VSEngineering Contradiction Analysis

1Measurement precision

If the reception area or transmission area of the antenna is divided into a plurality of spatial sectors for detailed performance assessment, then the precision of antenna performance measurement is improved, but the device complexity increases due to the need to process multiple sector-specific parameters

Engineering Contradiction:

Solution Approach 1:

The reception area or transmission area of the antenna is divided into a plurality of spatial sectors. For each sector, performance parameters are determined and statistical values are calculated. This segmentation allows precise assessment of antenna performance in different spatial directions while managing complexity through structured processing of sector-specific data.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If statistical values are determined from performance parameters of multiple sectors to simplify antenna comparison, then the ease of operation is improved, but the measurement precision may be reduced by aggregating sector-specific data

Engineering Contradiction:

Solution Approach 1:

Statistical values are extracted from the performance parameters of multiple sectors. These statistical values represent the overall antenna performance while being derived from detailed sector-specific measurements. This extraction process simplifies antenna comparison and system assessment while preserving the essential performance characteristics captured in the original measurements.

Inventive Principle:

3Device complexity

If multiple antennas are assessed and designed individually before combining them into a system, then the device complexity is reduced, but the time required for complete system design increases

Engineering Contradiction:

Solution Approach 1:

Each antenna in the system is assessed and designed individually before being combined into the complete multiple-antenna system. This preliminary assessment of individual antennas simplifies the overall system design process by breaking it down into manageable components, while the standardized statistical value framework enables efficient integration and system-level optimization.
