Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If current radio network planning techniques are used for UAV traffic management, then device complexity is reduced, but measurement precision and reliability of 3D coverage data are insufficient

Engineering Contradiction:

Solution Approach 1:

The patent transitions from traditional 2D radio network planning to 3D coverage analysis by incorporating altitude information and vertical dimension parameters. This enables accurate representation of UAV connectivity in three-dimensional space, resolving the insufficiency of conventional 2D techniques for 3D flight environments.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The system integrates multiple data sources including stored network data, current connectivity data, and 3D coverage data into a unified framework. This multi-functional approach allows the same system to handle both traditional 2D ground network planning and 3D aerial UAV traffic management, reducing overall system complexity while improving measurement precision.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Reliability

If real-time 3D network coverage data is computed and reported, then reliability and safety of UAV operation are improved, but loss of time and productivity increase due to data processing

Engineering Contradiction:
ImproveUAV operation safetyVSAvoiddata processing time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system pre-computes and stores network coverage data in three dimensions before UAV operations begin. This preliminary action allows real-time queries during flight to simply retrieve pre-calculated coverage information rather than performing complex computations, thereby maintaining high reliability while minimizing time loss.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent replaces traditional mechanical real-time computation with an information-based retrieval system. By pre-calculating and storing 3D coverage data, the system substitutes complex real-time mathematical computations with faster data lookup and correlation operations, reducing processing time while maintaining safety and reliability.

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

3Reliability

Engineering Contradiction:

Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system calculates handover probability and interference data specifically for relevant 3D locations and scenarios rather than uniformly across all possible configurations. This localized approach focuses computational resources on critical areas where connection stability is most challenging, improving reliability without proportionally increasing overall system complexity.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent introduces an intermediary processing layer that correlates stored network data with current connectivity data to derive handover probability and interference metrics. This intermediary layer abstracts the complexity of calculating these parameters, presenting simplified reliable data to the UAV guidance system while handling the complex computations internally.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Productivity

If prompt adaptation of flight paths to changing network conditions is enabled, then productivity and efficiency of UAV operation are improved, but measurement precision requirements and device complexity increase

Engineering Contradiction:

Core Design Contradiction:

Solution Approach 1:

The system implements continuous feedback loops where current connectivity data is constantly monitored and correlated with stored 3D coverage data. This feedback mechanism enables real-time detection of network condition changes and automatic flight path adjustments, improving productivity while maintaining manageable measurement precision requirements through iterative refinement.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent enables dynamic flight path adaptation by making the UAV guidance system responsive to changing network conditions. Rather than static pre-planned paths, the system continuously adjusts flight parameters based on real-time 3D coverage data, handover probabilities, and interference levels, thereby improving operational efficiency without requiring excessive measurement precision at any single moment.

Inventive Principle:

AI summary

The present disclosure provides an apparatus and a method for computing data for guiding unmanned aerial vehicles (UAVs) in a three-dimensional (3D) air space. Stored network data including location data of network nodes as well as current network data including current connectivity data of the network nodes are acquired. By correlating the stored and current network data, current 3D coverage data indicating current network coverage along three dimensions in the 3D flight area (e.g. a handover probability or an interference caused by a UAV) are determined. The techniques of the present disclosure enable modeling and predicting a current coverage and connectivity state of 3D air space and facilitates control and operation of UAV air traffic.
