1Reliability

If transmission power is increased to overcome interference, then signal quality improves, but transmission power regulations are violated

Engineering Contradiction:

Solution Approach 1:

The system performs preliminary detection of interference sources and their trajectories before transmission occurs. By predicting future interference positions, the system can pre-adjust resource allocation and transmission parameters to maintain signal quality without exceeding power limits.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system dynamically adapts transmission parameters based on real-time interference detection and prediction. Transmission power, frequency resources, and time slots are continuously adjusted according to predicted interference trajectories, allowing optimal signal quality within regulatory power constraints.

Inventive Principle:

2Power

If transmission power is reduced to comply with regulations, then power consumption decreases, but signal-to-noise ratio deteriorates due to interference

Engineering Contradiction:

Improvetransmission powerVSAvoidsignal-to-noise ratio

Core Design Contradiction:

PowerVSReliability

Solution Approach 1:

The system converts the harmful effect of interference into useful information by detecting and tracking interferer trajectories. This interference intelligence is then used to predict future interference positions and proactively allocate resources, turning the presence of interferers into an opportunity for optimized resource management that maintains SNR despite low transmission power.

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

Solution Approach 2:

The system implements continuous feedback loops where interference detection results feed into trajectory prediction, which then feeds into resource allocation decisions. This closed-loop control allows the system to maintain optimal SNR by dynamically adjusting transmission parameters based on actual interference conditions while staying within power regulations.

Inventive Principle:

Principle #23Feedback

3Reliability

Core Design Contradiction:

Solution Approach 1:

The interference detector is designed to perform multiple functions: detecting current interference, tracking interferer trajectories, predicting future interference positions, and providing information for resource allocation. This multi-functional approach consolidates what could be separate complex systems into a single integrated component, reducing overall system complexity while maintaining comprehensive interference mitigation.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Core Design Contradiction:

Measurement precisionVSQuantity of substance

Solution Approach 1:

The system implements partial interference tracking by focusing computational resources on detecting and predicting only the most significant interferers whose trajectories will impact communication resources. Rather than tracking all possible interferers equally, the system identifies and prioritizes critical interferers, achieving sufficient prediction accuracy with reduced resource consumption for detection and tracking.
