Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If machine learning models are used to predict weather conditions based on channel state information, then network adaptability to weather changes is improved, but the complexity of the system increases due to the need for large datasets and processing capabilities

Engineering Contradiction:
Improvenetwork adaptabilityVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system performs preliminary weather prediction using machine learning models based on historical and current channel state information before actual weather conditions affect communication. This advance prediction allows the network to proactively adjust configurations (such as beamforming parameters, frequency selection, and power allocation) in anticipation of weather changes, thereby improving adaptability without requiring complex real-time adjustments when weather conditions actually change

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent introduces sensor fusion as an intermediary layer between the physical weather environment and the communication system. Sensors (such as temperature, humidity, and pressure sensors) act as mediators that convert complex weather conditions into simplified channel state information that can be processed by machine learning models. This intermediary approach simplifies the overall system complexity by providing structured, processable data while maintaining high adaptability to weather changes

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If network configurations are adjusted in real-time based on weather predictions, then communication reliability is improved, but the time and computational resources required for processing increase

Engineering Contradiction:
Improvecommunication reliabilityVSAvoidprocessing time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system implements periodic weather prediction and network configuration adjustment cycles rather than continuous real-time processing. The machine learning model predicts weather conditions at predetermined intervals, and network configurations are adjusted periodically based on these predictions. This periodic approach maintains communication reliability by ensuring regular updates while reducing computational burden and processing time compared to continuous real-time adjustment

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The system performs preliminary weather prediction and configuration preparation in advance of actual weather events. By analyzing historical channel state information and sensor data beforehand, the machine learning model prepares prediction results that can be quickly applied when weather changes occur. This preliminary action reduces the critical processing time needed during actual weather events while maintaining high communication reliability

Inventive Principle:
Principle #10Preliminary action

3Measurement precision

If sensor fusion is implemented to collect data from multiple sources, then measurement precision of weather conditions is improved, but the device complexity and power consumption increase

Engineering Contradiction:
Improveweather prediction accuracyVSAvoidpower consumption
Core Design Contradiction:
Measurement precisionVSUse of energy by stationary object

Solution Approach 1:

The system implements partial sensor fusion by selectively activating and using only the most relevant sensors based on current conditions and prediction needs. Rather than continuously operating all sensors at full capacity, the system activates specific sensors (such as temperature, humidity, or pressure sensors) only when their data is most valuable for weather prediction. This partial action approach maintains high measurement precision while significantly reducing overall power consumption compared to full-time operation of all sensors

Inventive Principle:
Principle #16Partial or excessive action

Solution Approach 2:

The machine learning model performs self-optimization of sensor data collection by automatically determining which sensors to activate and how frequently to sample based on historical patterns and current channel state information. The system learns to allocate sensor resources efficiently without external intervention, activating only the necessary sensors for accurate weather prediction while minimizing power consumption. This self-service capability maintains high measurement precision while reducing the energy overhead of sensor fusion

Inventive Principle:
Principle #25Self-service
