VSEngineering Contradiction Analysis

1Measurement precision

If analytical functions are used to evaluate sector complexity, then measurement precision is improved, but calculation time increases significantly

Engineering Contradiction:
Improvecomplexity evaluation precisionVSAvoidcalculation time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent segments the complexity evaluation into two distinct phases: an offline training phase where the neural network is trained using comprehensive analytical functions to learn complex patterns, and an online evaluation phase where the trained network provides rapid predictions. This segmentation allows the system to benefit from both the precision of complex analytical methods and the speed of simplified calculations at runtime.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system performs preliminary action by training the neural network offline using extensive analytical complexity evaluations before actual sector management operations. This pre-computation stores the learned patterns in the network weights, enabling fast online evaluations without repeating the computationally intensive analytical calculations during time-critical operations.

Inventive Principle:
Principle #10Preliminary action

2Adaptability or versatility

If manual assignment of controllers to sectors is used, then adaptability is improved, but productivity decreases

Engineering Contradiction:
Improvecontroller allocation adaptabilityVSAvoidsector management efficiency
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The patent implements dynamic sector management where sector definitions and controller allocations are continuously adjusted based on real-time complexity evaluations. The system can dynamically create, merge, or split sectors and reassign controllers automatically according to current traffic conditions, replacing static manual assignments with adaptive automated decisions that respond to changing operational requirements.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system incorporates feedback loops where complexity evaluation results are continuously fed back to the sector management module, which then adjusts sector configurations and controller assignments accordingly. This closed-loop control enables automatic adaptation to changing traffic patterns without manual intervention, improving both productivity and adaptability simultaneously.

Inventive Principle:
Principle #23Feedback

3Reliability

If complex analytical functions are used for sector complexity evaluation, then reliability is improved, but device complexity increases

Engineering Contradiction:
Improvecomplexity evaluation reliabilityVSAvoidcalculation system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces the mechanical execution of complex analytical functions during online operations with a neural network-based computational model. The neural network, once trained, performs evaluations through simple forward propagation calculations rather than executing complex analytical algorithms, significantly reducing computational complexity while preserving the reliability gained from training on comprehensive data.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system creates a simplified copy of the complex analytical evaluation capability through the neural network model. The network learns and replicates the decision-making patterns of the analytical functions during training, then uses this learned representation to perform evaluations efficiently during operation, maintaining reliability while reducing computational burden.

Inventive Principle:
Principle #26Copying

AI summary

In the field of air traffic control, a method is provided to determine a processing complexity of an ATC situation. For this purpose, the method includes grouping parameters of the paths by pairs of paths in a matrix, applying to this matrix a transformation aiming to concentrate the energy, then calculating the complexity index of the ATC situation as a function of the concentration level of the energy per component.
