Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of energy

If beam configuration is adjusted to match user distribution and service demand, then energy consumption is reduced, but system complexity increases

Engineering Contradiction:
Improvebase station energy consumptionVSAvoidbeam configuration complexity
Core Design Contradiction:
Loss of energyVSDevice complexity

Solution Approach 1:

The patent segments the beam configuration management into multiple independent components: beam clustering modules that group beams by spatial characteristics, traffic prediction modules that forecast user demand, and configuration adjustment modules that optimize parameters. This segmentation allows each component to handle specific tasks independently, reducing overall system complexity while achieving energy savings through coordinated operation of these modular elements.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent implements dynamic beam configuration where clustering patterns, traffic predictions, and configuration parameters are continuously adjusted based on real-time user distribution and service demand. This dynamic approach allows the system to adapt to changing conditions automatically, reducing the need for complex manual configuration management while optimizing energy consumption through time-varying parameter adjustment.

Inventive Principle:
Principle #15Dynamics

2Reliability

If beam configuration is optimized for specific user distributions and service types, then service quality is improved, but adaptability to varying conditions deteriorates

Engineering Contradiction:
Improveservice qualityVSAvoidadaptability to user distribution variations
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent employs traffic prediction functionality that forecasts future user distribution and service demand patterns before they fully materialize. By performing preliminary action based on predicted conditions, the system pre-adjusts beam configurations to anticipate changes in user distribution, thereby maintaining high service quality while being proactively adaptive to varying conditions rather than reactively responding to them.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent implements feedback mechanisms where the system continuously monitors actual user distribution and service quality metrics, compares them against predicted values, and uses this feedback to refine both traffic predictions and beam configuration decisions. This closed-loop feedback ensures the system adapts to varying conditions while maintaining optimized service quality through data-driven adjustments.

Inventive Principle:
Principle #23Feedback
