VSEngineering Contradiction Analysis

1Adaptability or versatility

If mobile base stations are deployed to provide cellular coverage in dynamic environments, then network coverage and mobility support are improved, but interference between base stations increases due to unpredictable trajectories

Engineering Contradiction:

Improvenetwork coverageVSAvoidinterference

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The patent implements dynamic reconfiguration of base station parameters (frequency, power, antenna orientation) based on real-time operating indicators and predicted trajectories. This allows the network to adapt to changing spatial relationships between mobile base stations and maintain coverage while minimizing interference through continuous adjustment of operational parameters.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system collects operating indicators from base stations and uses this feedback to determine and execute reconfiguration actions. The feedback loop enables the network to detect interference conditions and respond by adjusting base station parameters, thereby reducing harmful interference while maintaining network coverage.

Inventive Principle:

Principle #23Feedback

2Object-affected harmful factors

If base station reconfiguration actions are implemented to reduce interference, then interference levels are reduced, but network operation stability may be affected due to frequent adjustments

Engineering Contradiction:

Core Design Contradiction:

Object-affected harmful factorsVSStability of the object's composition

Solution Approach 1:

The system determines reconfiguration actions based on collected operating indicators before interference fully develops. By taking preliminary action to adjust base station parameters based on predicted trajectories and current operating conditions, the system prevents interference rather than reacting to it, thereby maintaining network stability while reducing harmful effects.
