Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

The increasing popularity of UAVs leads to conflicts in flight paths, causing potential safety hazards and economic losses due to collisions and unauthorized flights into no-fly areas.

Innovation Solution

Uncrewed aerial vehicles share flight path information through sidelinks, detect collision risks, and update paths autonomously or upon instruction from UTM nodes or access network devices to avoid collisions and ensure legality.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If UAVs fly autonomously without centralized coordination, then flight flexibility and operational speed are improved, but collision risk and flight path conflicts increase

Engineering Contradiction:

Improveflight operational speedVSAvoidcollision avoidance

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The system performs preliminary actions by having UAVs report their flight path information to the network device before actual flight operations. The network device pre-calculates and determines optimal flight paths for multiple UAVs, identifying potential collision risks in advance and preparing coordinated flight routes, thereby preventing collisions before they occur while maintaining flight speed.

Inventive Principle:

Principle #10Preliminary action

2Productivity

If multiple UAVs operate in the same area without path coordination, then service coverage and operational capacity are improved, but flight path conflicts and safety hazards worsen

Engineering Contradiction:

Improveoperational capacityVSAvoidflight path conflicts

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The system implements feedback mechanisms where UAVs continuously report their flight path information to the network device. The network device receives this information, analyzes potential conflicts, and sends back coordinated flight path instructions to individual UAVs. This closed-loop feedback system enables multiple UAVs to operate simultaneously in the same area while maintaining safety through continuous monitoring and adjustment.

Inventive Principle:

Principle #23Feedback

3Adaptability or versatility

If UAVs use unauthorized flight paths, then operational flexibility is improved, but legal compliance and safety management deteriorate

Engineering Contradiction:

Improveflight path flexibilityVSAvoidlegal compliance

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The system employs dynamic flight path determination where the network device receives real-time flight path information from UAVs and dynamically adjusts recommended routes based on current operational conditions, other UAV positions, and legal requirements. This allows UAVs to maintain flexibility in adapting to changing conditions while ensuring all flight paths remain within legal boundaries through centralized oversight.

Inventive Principle:

Principle #15Dynamics
