Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The proliferation of Unmanned Aerial Vehicles (UAVs) for package delivery poses challenges in air traffic control, including balancing loads to prevent accidents and ensuring safe navigation, as existing air traffic control networks are overwhelmed and impractical for managing the large number of UAVs.
Innovation Solution
A method for optimizing the loading of UAVs by determining the Center of Gravity (COG) of multiple objects, including the UAV, container, and items, to ensure balanced and safe flight, using wireless networks for communication and control, and implementing systems for collision avoidance, obstruction detection, and flying lane management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the existing air traffic control network is used for UAV management, then comprehensive control and monitoring can be provided, but the system becomes overwhelmed and impractical due to the large number of UAVs
Solution Approach 1:
The patent segments the air traffic control function by introducing autonomous UAV-to-UAV communication and coordination capabilities. Each UAV becomes a node that can independently detect, communicate, and coordinate with other UAVs, distributing the control function across the network rather than relying on a centralized system that becomes overwhelmed.
Solution Approach 2:
The patent enables UAVs to perform self-service through autonomous navigation, self-detection of other UAVs, and automated coordination algorithms. Each UAV independently manages its own flight path and collision avoidance, reducing the burden on external air traffic control infrastructure.
2Quantity of substance
If UAVs carry heavy loads for package delivery, then delivery capacity increases, but the UAVs become imbalanced and unsafe for flight
Solution Approach 1:
The patent implements preliminary action by calculating and optimizing the center of gravity configuration before each flight. The system determines the optimal placement of packages and counterweights in advance, ensuring proper balance is achieved before the UAV takes off, thereby preventing flight instability and safety issues.
Solution Approach 2:
The patent applies parameter changes by dynamically adjusting the center of gravity position through strategic placement of packages and counterweights. The system modifies the weight distribution parameters to achieve optimal balance, allowing the UAV to safely carry heavy loads while maintaining flight stability.
3Productivity
If UAVs operate autonomously with increased numbers, then delivery efficiency improves, but collision risk and navigation safety deteriorate
Solution Approach 1:
The patent implements feedback mechanisms where UAVs continuously detect and communicate the positions and status of other UAVs in real-time. This feedback loop enables dynamic adjustment of flight paths and coordination to prevent collisions, allowing high-density autonomous operation to proceed safely.
Solution Approach 2:
The patent uses preliminary action by pre-calculating collision-free flight paths and coordinating UAV schedules before flights begin. The system anticipates potential conflicts and resolves them in advance through automated coordination, enabling safe high-density operations without compromising delivery efficiency.
