Solution Overview

Problem

Unmanned aerial vehicles (UAVs) pose safety challenges due to unrestricted flight, potential loss of control, unauthorized operation, hijacking, and hacking, lacking effective safety mechanisms for flight regulation and user authentication.

Innovation Solution

A system and method for controlling UAVs that includes a communication module and processors to receive user and UAV identifiers, generate and transmit flight regulations, and implement authentication processes to ensure only authorized parties can operate the UAV, using geo-fencing devices to enforce flight restrictions and override manual controls.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If flight of UAVs is unrestricted to maintain ease of operation, then ease of operation is improved, but safety and security deteriorate due to potential loss of control, unauthorized operation, hijacking, and hacking

Engineering Contradiction:
Improveease of operationVSAvoidsafety and security
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent introduces an authentication center as an intermediary between the UAV and users. This center performs mutual authentication with the UAV before allowing operation, and also authenticates remote controllers. This intermediary mechanism enables restricted flight operations while maintaining ease of use for authorized users, resolving the contradiction between unrestricted operation and safety/security.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If authentication mechanisms are implemented to improve safety and security, then reliability is improved, but device complexity increases due to authentication center and mutual authentication protocols

Engineering Contradiction:
Improvesafety and securityVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The authentication center performs mutual authentication with the UAV autonomously without requiring manual intervention from users. The UAV and authentication center automatically verify each other's identities through cryptographic protocols, and the system automatically manages authentication states. This self-service approach improves safety and security while minimizing the complexity burden on users and operators.

Inventive Principle:
Principle #25Self-service

3Reliability

If geo-fencing devices are used to enforce flight regulations, then safety is improved by preventing unauthorized flight areas, but ease of operation deteriorates due to restricted flight zones and overridden manual controls

Engineering Contradiction:
ImprovesafetyVSAvoidease of operation
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The system pre-establishes geo-fence boundaries and flight regulation zones before UAV operation. The authentication center stores geographic boundary data and automatically enforces these pre-defined restrictions during flight. By performing the boundary definition and restriction setup in advance, the system ensures safety through enforced flight regulations while maintaining ease of operation during actual flight, as users do not need to manually manage restrictions during operation.

Inventive Principle:
Principle #10Preliminary action
