Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a fixed unit time is set for extracting frame feature values, then the analysis process becomes simple and systematic, but the analysis accuracy deteriorates when the actual transmission packet unit time is unknown or mismatched

Engineering Contradiction:

Improveanalysis process simplicityVSAvoidframe feature value extraction accuracy

Core Design Contradiction:

Ease of operationVSMeasurement precision

Solution Approach 1:

The patent applies dynamics by making the acquisition period variable rather than fixed. The system dynamically adjusts the acquisition period based on detected transmission patterns, allowing the analysis window to adapt to actual network conditions. This resolves the contradiction by enabling both operational simplicity (through automated adaptation) and extraction accuracy (through pattern-matched timing).

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system changes the time parameter (acquisition period) based on detected transmission characteristics. By monitoring transmission patterns and adjusting the acquisition period accordingly, the system optimizes the extraction of frame feature values without requiring manual configuration, thus maintaining simplicity while improving accuracy.

Inventive Principle:

Principle #35Parameter changes

2Measurement precision

If the acquisition period is extended to ensure capturing complete transmission cycles, then the analysis accuracy improves, but the analysis time increases

Engineering Contradiction:

Improveframe feature value extraction accuracyVSAvoidanalysis time

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The system uses feedback from detected transmission patterns to optimize the acquisition period. By continuously monitoring transmission characteristics and adjusting the acquisition period based on this feedback, the system achieves accurate frame feature extraction in the minimum necessary time, avoiding both premature termination and excessive waiting.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The system performs preliminary detection of transmission patterns before conducting the full analysis. This preliminary action allows the system to pre-determine the optimal acquisition period based on observed patterns, ensuring that the subsequent analysis captures complete transmission cycles without unnecessary delays.

Inventive Principle:

Principle #10Preliminary action

Core Design Contradiction:

Solution Approach 1:

The system dynamically determines the acquisition period based on real-time detection of transmission patterns. This allows the acquisition period to be as short as necessary to capture complete transmission cycles, optimizing both analysis speed and accuracy by avoiding both premature termination and excessive waiting.

Inventive Principle:

Core Design Contradiction:

Solution Approach 1:

The system performs self-configuration by automatically detecting transmission patterns and determining the optimal acquisition period without manual intervention. This self-service capability maintains high extraction accuracy while eliminating the complexity of manual configuration, allowing the system to adapt to different network conditions autonomously.

AI summary

An appropriate time is set as an acquisition period during which a reception data sequence for extracting a frame feature value is acquired. A radio frame analysis system includes a transmission node number count unit that counts the number of transmission nodes from a reception data sequence, an acquisition period calculation unit that calculates an acquisition period based on a result of the counting by the transmission node number count unit, and a frame feature value extraction unit that extracts a frame feature value of each of the transmission nodes from the reception data sequence received in the acquisition period.
