Robot-Assisted Airlifting for Direct Cargo Unloading and Ground Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional commodities airlifting systems are inefficient at airports with few arrival-and-departure flights, leading to idle time during operations like unloading and ground transport, and require additional equipment for cargo handling, especially in disaster scenarios where rapid operations are necessary.
Innovation Solution
A commodities airlifting system utilizing a self-propellable robot with a robotic arm, an aircraft, and a drone, equipped with a lowering/loading apparatus, enabling direct unloading and loading of commodities at the destination location, allowing for autonomous or remote-controlled operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional cargo aircraft and cargo vehicles are used for airlifting, then cargos can be transported from departure to destination, but idle time occurs during unloading and ground transport operations at airports with few flights
Solution Approach 1:
The patent combines the cargo transport function and ground transport function into a single integrated system. The robot performs both aerial transport (as cargo) and ground transport (as a functional unit), eliminating the idle time between unloading and ground transport operations. This merging of functions resolves the contradiction by making the system continuously productive throughout the entire logistics chain.
Solution Approach 2:
The robot is designed as a multi-functional unit that can serve both as cargo (being transported by aircraft) and as a functional device (performing unloading and ground transport operations). This universality allows the same physical entity to fulfill multiple roles, eliminating idle time and improving overall operational efficiency at airports with limited flight schedules.
2Ease of operation
If additional material handling equipment such as forklifts and K-loaders are used for cargo operations, then cargos can be handled at destination, but device complexity and operational requirements increase
Solution Approach 1:
The patent extracts the cargo handling functions from separate external equipment (forklifts, K-loaders) and integrates them directly into the robot itself. The robot is equipped with its own cargo handling capabilities, eliminating the need for additional material handling equipment at the destination. This extraction principle resolves the contradiction by simplifying the overall system while maintaining full cargo handling capability.
Solution Approach 2:
The robot performs cargo handling operations autonomously without requiring external assistance from forklifts or K-loaders. The system is self-sufficient, with the robot capable of unloading cargo and performing ground transport operations independently. This self-service capability reduces device complexity while maintaining ease of operation.
3Productivity
If conventional cargo systems are used for disaster relief supply airlifting, then supplies can be transported to disaster areas, but additional equipment and operations are needed for unloading and ground transport to disaster sites
Solution Approach 1:
The patent merges multiple operational functions (aerial transport, unloading, and ground transport to disaster sites) into a single integrated robot system. This eliminates the need for multiple separate operations and equipment, enabling rapid response to disaster areas while reducing operational complexity. The robot can directly deliver supplies from the aircraft to the final destination without requiring additional equipment at the disaster site.

AI summary
A commodities airlifting system includes a self-propellable robot 1, an aircraft 2 which carries commodities 21 and the robot 1, and a lowering/loading apparatus 3 which at least enables the robot 1 to get off on the ground from the aircraft 2 and to get on the aircraft 2 from the ground, in a state where the aircraft 2 is landed or a state where the aircraft 2 is hovering. The robot 1 which got off on the ground from the aircraft 2 again gets on an aircraft 2.
