Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current methods for transferring control of drones between control entities are inefficient and do not guarantee continuous, secure control, as they rely on manual triggering and may not ensure that only one control entity is in control at a given time.

Innovation Solution

A method that detects events triggering control transfers within a drone traffic management system, using a list of authorized control entities with parameters for transfer conditions, including priority levels, to establish a new control data stream, ensuring seamless and secure handover of drone control.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If control transfer is triggered manually through existing procedures, then control can be transferred between entities, but the process is slow and does not guarantee continuous control

Engineering Contradiction:

Improvecontrol transfer speedVSAvoidcontrol continuity

Core Design Contradiction:

SpeedVSReliability

Solution Approach 1:

The system pre-establishes a list of authorized control entities with their priorities before control transfer is needed. When control transfer is required, the system can immediately identify and connect to the next authorized entity without manual intervention or delays, ensuring both speed and continuity of control.

Inventive Principle:

Principle #10Preliminary action

2Adaptability or versatility

If multiple control entities are authorized to control the drone, then control transfer is possible, but it becomes unclear which entity should control the drone at any given time

Engineering Contradiction:

Improvecontrol entity flexibilityVSAvoidcontrol entity identification

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

Each control entity in the authorized list is assigned a specific priority level (first priority, second priority, etc.). This creates a clear hierarchy where the system always knows which entity should control the drone based on their position in the prioritized list, eliminating confusion while maintaining flexibility.

Inventive Principle:

Principle #3Local quality

3Reliability

If control transfer procedures involve multiple system interactions, then comprehensive control management is achieved, but the number of data exchanges increases and efficiency decreases

Engineering Contradiction:

Improvecontrol management completenessVSAvoidcontrol transfer efficiency

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The patent combines multiple control management functions into a single integrated system. The system that manages authorized control entities also handles the actual control transfer by establishing direct communication channels, eliminating the need for multiple separate data exchanges and intermediate systems.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

A method for transferring to a second control entity control of a remotely-controlled vehicle, called a drone, from a first control entity exercising control of the drone via a first control data stream transmitted through a first communication session established between the first control entity and the drone. The method includes: detecting an event triggering transfer of control of the drone; determining the second control entity by using a list of control entities possessing an authorization for control of the drone, the list including at least one parameter relating to a condition for transferring control of the drone to the second control entity; and establishing transmission of a second control data stream through a second communication session between the drone and the second control entity, the establishment of the second control data stream contributing to an end of the control exercised by the first control entity over the drone.
