Modular UAV Cargo Compartments for Multi-Payload Aerial Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current unmanned aerial vehicles (UAVs) for cargo delivery are limited to single cargo per trip, require tethered tow lines, and have cargo systems inseparably integrated, necessitating different UAVs for different types of cargo.
Innovation Solution
A modular UAV design with a compartmentalized airframe featuring an integrated ring structure, detachable compartments, and a smart lock system, allowing multiple cargo types to be transported in a single trip.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a modular compartmentalized design is used, then the adaptability and productivity are improved by enabling multiple cargo types per trip, but the device complexity increases due to multiple detachable compartments and smart lock systems
Solution Approach 1:
The cargo delivery system is divided into multiple detachable compartments that can be independently configured and removed. Each compartment can be customized for specific cargo types, allowing the UAV to adapt to different delivery requirements without redesigning the entire system. The compartments feature standardized interfaces for easy attachment and detachment.
Solution Approach 2:
The UAV platform is designed with a universal base structure that can accommodate various types of compartments through standardized mounting interfaces. The smart lock system provides a unified control mechanism for all compartments, enabling a single UAV to perform multiple cargo delivery functions across different scenarios and cargo types.
2Strength
If an integrated ring structure is used, then the strength and stability are improved, but the manufacturing precision requirements increase due to the continuous joint-free structure
Solution Approach 1:
Multiple structural components are merged into a single continuous integrated ring structure that forms the main airframe. This unified structure eliminates joints and connection points that would otherwise be potential weak points, creating a stronger and more stable platform while distributing mechanical loads evenly throughout the structure.
3Reliability
If tethered tow lines are used for cargo delivery, then the reliability is improved by maintaining physical connection, but the productivity decreases by limiting to single cargo per trip
Solution Approach 1:
The cargo delivery system is divided into multiple detachable compartments that can be independently configured and removed. Each compartment can be customized for specific cargo types, allowing the UAV to adapt to different delivery requirements without redesigning the entire system. The compartments feature standardized interfaces for easy attachment and detachment.
Solution Approach 2:
The system enables rapid detachment and recovery of cargo compartments during flight operations. After delivering cargo from one compartment, the UAV can quickly detach that compartment and attach a different one for the next delivery, maintaining continuous operational productivity while ensuring reliable delivery through controlled detachment mechanisms.

AI summary
Disclosed herein is an unmanned aerial vehicle (UAV) for facilitating aerial deliveries of cargos. The UAV includes a body, a propulsion assembly, a compartment defining element, and a lid. The body defines a receptacle having a receptacle opening. The propulsion assembly is attached to the body. The propulsion assembly is configured for aerially propelling the UAV. The compartment defining element is disposed in the receptacle for defining a compartment in the receptacle with a compartment characteristic. Further, a compartment interior space and a compartment opening of the compartment are defined based on the compartment characteristic. The cargo is removably receivable in the compartment interior space through the compartment opening. The lid is coupled to the body. The lid is configured for transitioning the compartment between an opened state and a closed state.
