Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If existing communication systems for UAVs are used, then basic connectivity is provided, but efficient mechanisms for immediate or deferred network actions based on UAV operations and operator-defined policies are lacking

Engineering Contradiction:
Improvepolicy control exposure serviceVSAvoidnetwork action mechanism
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent introduces a network entity that acts as an intermediary between the UAV and the core network functions. This intermediary receives monitoring requests from UAV control entities, subscribes to relevant events through existing network functions, and distributes event reports to appropriate subscribers. This mediator approach enables policy control exposure services without requiring direct modifications to existing network architecture, thus improving adaptability while managing complexity.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The network entity performs multiple functions: receiving monitoring requests, subscribing to events, distributing event reports, and supporting both immediate and deferred network actions. By consolidating these diverse functions into a single multi-functional entity, the system achieves high versatility for different policy control scenarios without proportionally increasing overall system complexity.

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

2Speed

If immediate network actions are enabled for UAV operations, then response time is improved, but control and coordination complexity increases

Engineering Contradiction:
Improvenetwork response timeVSAvoidcontrol coordination mechanism
Core Design Contradiction:
SpeedVSDevice complexity

Solution Approach 1:

The system enables deferred network actions where the network entity can prepare and stage network actions in advance based on monitored events, then execute them at predetermined times or conditions. This preliminary action capability allows the system to improve response time for critical events while maintaining the option to delay non-critical actions, thereby managing control coordination complexity through time-based differentiation.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The network entity dynamically adjusts its behavior based on event type and subscriber preferences, selecting between immediate and deferred action modes. This dynamic approach allows the system to optimize response time for urgent matters while reducing control complexity for routine operations, achieving speed improvement without uniform complexity increase across all operations.

Inventive Principle:
Principle #15Dynamics

3Reliability

If comprehensive event monitoring and policy control exposure services are implemented, then UAS operation management effectiveness is improved, but system complexity increases

Engineering Contradiction:
ImproveUAS operation managementVSAvoidevent monitoring system
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent segments the event monitoring and policy control functions into distinct modular components: event subscription modules, event report distribution modules, and policy execution modules. Each module handles specific aspects of UAS operation management independently. This segmentation improves reliability by isolating failures to specific modules while maintaining overall system functionality, and manages complexity through clear module boundaries and specialized responsibilities.

Inventive Principle:
Principle #1Segmentation

AI summary

Methods, apparatus and systems are disclosed. In one embodiment, a method, implemented by a UAS control entity includes the UAS control entity: receiving, from a USS/UTM, a monitoring request including information indicating a uncrewed/unmanned aerial vehicle (UAV) identifier to be monitored and one or more types of events the USS/UTM is subscribing to; subscribing with a network entity serving a UAV associated with the UAV identifier to be monitored based on the information indicating a type of event; receiving a published event report from the network entity, the publish event report including information indicating the UAV identifier, the event type and meta information related to an event; and sending the published event report received to the USS/UTM.
