Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If XR data is transmitted in real-time at high speed, then user experience is improved, but objective measurement of transmission impact becomes difficult
Solution Approach 1:
The patent introduces an intermediary measurement mechanism that uses packet delay budget (PDB) information and transmission error information as mediators to objectively assess XR data transmission quality. These intermediaries bridge the gap between high-speed transmission and measurable impact by providing quantifiable metrics that reflect user experience without requiring direct subjective measurement during real-time transmission.
2Reliability
If transmission quality is evaluated subjectively through user experience, then user perspective is captured, but systematic network optimization cannot be achieved
Solution Approach 1:
The patent implements a feedback mechanism where transmission quality indicators (XQI) are calculated based on PDB information and transmission error information, then fed back to guide network optimization. This feedback loop transforms subjective user experience into objective, actionable metrics that systematically inform network adjustments and improvements.
Solution Approach 2:
The patent changes the parameters used for quality evaluation from subjective user experience reports to objective transmission parameters including PDB information, transmission error information, and XQI metrics. This parameter transformation enables systematic measurement and optimization while maintaining correlation with user experience quality.
3Measurement precision
If multiple delay information types are used (PDB, delay variation, average delay, delay variance), then delay impact evaluation becomes comprehensive, but system complexity increases
Solution Approach 1:
The patent segments delay evaluation into multiple independent information types (PDB information, delay variation information, average delay information, delay variance information), each measuring a specific aspect of delay impact. This segmentation allows comprehensive evaluation while managing complexity by treating each delay metric as a separate, manageable component that contributes to the overall XQI calculation.
