UAV Remote Locking via Server Commands for Lease Control

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current UAV control systems do not allow owners to regain control promptly when the lease expires or when operators exhibit unreasonable behavior, leading to inconvenience and potential misuse.

Innovation Solution

A method involving a server and remote control device that receives locking instruction information from a user terminal, transmitting a locking command to the remote control device to lock the UAV, ensuring the owner can regain control and prevent unauthorized continued operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the UAV is leased to an operator, then the operator can use the UAV to perform tasks, but the owner cannot regain control promptly when the lease expires or when the operator exhibits unreasonable behavior

Engineering Contradiction:

ImproveOwner's control over UAVVSAvoidTime delay in regaining control

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The system pre-establishes a locking mechanism and authorization framework before the lease begins. The owner can pre-configure lock conditions (lease expiration, unreasonable behavior) and the system automatically executes locking actions without requiring real-time intervention, thus eliminating time delay in regaining control.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system continuously monitors lease status and operator behavior through feedback mechanisms. When predefined conditions are met (lease expiration or unreasonable behavior detected), the system automatically triggers the locking function, ensuring timely control recovery without manual intervention delays.

Inventive Principle:

Principle #23Feedback

2Reliability

If the owner authorizes a company's UAV operator to operate the UAV, then the task can be accomplished by professionals, but the owner does not have direct control of the flight

Engineering Contradiction:

ImproveTask completion qualityVSAvoidOwner's direct control

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The system introduces an intermediary authorization mechanism between the owner and professional operator. The owner retains ultimate control through the ability to lock/unlock the UAV and set operational parameters, while the professional operator gains controlled access during the lease period. This intermediary layer reconciles the need for both professional operation and owner control.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Ease of operation

If the remote control device receives operation commands from an operator, then the UAV can be controlled to fly, but the device cannot execute commands when locked

Engineering Contradiction:

ImproveUAV flight controlVSAvoidCommand execution control

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The command execution capability of the remote control device is made dynamic rather than static. The device automatically adjusts its operational state based on the locking status: when unlocked, it freely executes operator commands; when locked, it blocks command execution. This dynamic adaptation allows the same device to serve both operational and security functions without requiring separate systems.

Inventive Principle:

Principle #15Dynamics

AI summary

A method for controlling an unmanned aerial vehicle (“UAV”) includes receiving locking instruction information from a user terminal for locking the UAV. The method also includes transmitting a locking command to a remote control device of the UAV based on the locking instruction information, to instruct the remote control device to lock the UAV based on the locking command.
