UAV Package Loading Using Center-of-Gravity Characterization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The proliferation of Unmanned Aerial Vehicles (UAVs) for various applications, particularly package delivery, poses challenges in air traffic control due to their large numbers and the impracticality of using existing air traffic control networks, with issues such as imbalance leading to operational hazards and the need for efficient load balancing and communication systems.
Innovation Solution
A method for loading UAVs with items involves obtaining the Center of Gravity (COG) and physical characteristics of each item, categorizing them, and selecting appropriate UAVs based on these criteria, with the option of using different UAVs for balanced loading and adding counterbalances as needed, while leveraging wireless networks for communication and control.

Engineering Contradiction Analysis
1Quantity of substance
If UAVs carry heavy or imbalanced loads, then delivery capacity increases, but operational safety deteriorates (UAVs cannot lift off, drift, or spin)
Solution Approach 1:
The system performs preliminary characterization of packages (weight, dimensions, COG) before loading, and pre-calculates the optimal loading configuration to ensure balanced loads. This advance planning prevents operational safety issues during flight by ensuring UAVs are properly loaded before takeoff.
Solution Approach 2:
The system changes the parameters of package loading by transitioning from arbitrary loading to optimized loading configurations. By adjusting package positions and orientations based on COG calculations, the system maintains UAV balance while maximizing delivery capacity.
2Productivity
If the number of UAVs increases for package delivery, then delivery efficiency improves, but air traffic control complexity increases (impractical to use existing networks)
Solution Approach 1:
UAVs are equipped with autonomous navigation and communication capabilities, allowing them to self-manage their flight operations. This reduces the burden on external air traffic control systems and enables scalable deployment without proportionally increasing control complexity.
Solution Approach 2:
The patent replaces traditional mechanical air traffic control infrastructure with wireless communication networks. This substitution allows for more flexible and scalable management of UAV traffic without the constraints of dedicated control networks.
3Loss of time
If packages are loaded without characterization, then loading speed increases, but load balance deteriorates (causing operational hazards)
Solution Approach 1:
The system performs preliminary characterization of packages (weight, dimensions, center of gravity) before loading operations. This advance information allows for rapid determination of optimal loading configurations, maintaining fast loading speeds while ensuring proper load balance.
Solution Approach 2:
By pre-characterizing packages and having ready-to-use loading algorithms, the system skips time-consuming manual calculations and adjustments during the actual loading process. The characterization data enables rapid deployment of optimized loading configurations.
