Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Unmanned aerial vehicles (UAVs) can be compromised by unauthorized disassembly, which removes safety limitations on flight height and area, potentially causing damage and security breaches.

Innovation Solution

Incorporating a detection device to identify unauthorized disassembly operations and a controller to prohibit UAV movement if such operations are detected, ensuring safety measures remain intact by only allowing authorized disassembly and operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the UAV allows disassembly for maintenance or modification, then ease of operation is improved, but reliability deteriorates due to potential unauthorized modifications

Engineering Contradiction:

Improveease of disassemblyVSAvoidsafety of flight parameters

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent applies preliminary action by pre-configuring detection devices that monitor disassembly operations before they can compromise safety. The system proactively detects unauthorized disassembly and prevents flight parameter modifications before they occur, rather than reacting after damage happens.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent implements feedback through detection devices that continuously monitor the UAV's assembly state and provide real-time information to the control system. When unauthorized disassembly is detected, the system immediately responds by preventing flight operations, creating a closed-loop safety mechanism.

Inventive Principle:

Principle #23Feedback

2Reliability

If the UAV implements strict safety measures through component limitations, then reliability is improved, but adaptability deteriorates due to inability to modify

Engineering Contradiction:

Improvesafety of flight parametersVSAvoidability to modify components

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent applies dynamics by making the safety restrictions conditional rather than fixed. The system dynamically adjusts its response based on whether disassembly is authorized: authorized disassembly allows component replacement while maintaining safety, whereas unauthorized disassembly triggers flight prevention. This dynamic approach resolves the contradiction between strict safety and modification flexibility.

Inventive Principle:

Principle #15Dynamics

3Reliability

If the UAV prevents any disassembly to maintain safety, then reliability is improved, but ease of operation deteriorates due to inability to perform maintenance

Engineering Contradiction:

Improvesafety of flight parametersVSAvoidability to perform maintenance

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent applies segmentation by dividing disassembly operations into authorized and unauthorized categories. The detection system segments monitoring based on authorization status, allowing legitimate maintenance disassembly while blocking unauthorized modifications. This segmentation resolves the contradiction by permitting necessary maintenance while preventing harmful actions.

Inventive Principle:

Principle #1Segmentation

AI summary

An unmanned aerial vehicle (UAV) including a detection device configured to detect that a disassembly operation has been performed on the UAV and a controller configured to determine whether the disassembly operation is an unauthorized disassembly operation, and prohibit the UAV from moving in response to the disassembly operation being the unauthorized disassembly operation, where the detection device is communicatively connected to the controller.
