Modular Aerostatic Lift for Extended-Range Package Delivery Drones
Solution Overview
Problem
Current drone-based systems for transporting and delivering packages suffer from limited autonomy and range due to their reliance on motorized propulsion alone, which restricts their operational capabilities.
Innovation Solution
An unmanned aerial system combining motorized aircraft with non-motorized aerostatic devices, such as helium-filled balloons, providing aerostatic lift that exceeds the weight of the package and the device, allowing for modular expansion of lift capacity through on-demand module distribution and coupling, enabling extended range and payload without speed limitations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple smaller UAVs are coupled together to form a collective drone, then the payload capacity is improved, but the device complexity increases
Solution Approach 1:
The system divides the lifting function into separate aerostatic modules that can be independently deployed and coupled to the UAV, allowing payload capacity to be segmented and scaled without increasing the complexity of the core UAV system
Solution Approach 2:
Aerostatic modules providing buoyant lift counterbalance the weight of packages and the UAV system, reducing the propulsion energy required and enabling heavier payload capacity without proportionally increasing device complexity
2Device complexity
If a single large UAV is used to carry a larger or heavier item, then the device complexity is reduced, but the payload capacity is limited by the UAV's weight and energy constraints
Solution Approach 1:
Aerostatic modules provide buoyant counterweight to offset package weight, enabling the UAV to carry heavier payloads without requiring a proportionally larger and more complex UAV structure
Solution Approach 2:
The system transitions from relying solely on aerodynamic lift (three-dimensional wing structure) to incorporating aerostatic buoyancy (vertical dimension), enabling payload capacity scaling without increasing UAV structural complexity
3Quantity of substance
If the aerostatic device uses a large volume to provide sufficient lift, then the payload capacity is improved, but the device complexity and storage requirements increase
Solution Approach 1:
The aerostatic lifting capacity is divided into multiple modular units that can be stored in compact forms and assembled on-demand, allowing large total lift capacity without requiring large individual storage volumes
Solution Approach 2:
Aerostatic modules are designed to be nested or collapsed into compact storage configurations when not in use, enabling large-volume lift-generating structures to be stored in small spaces and deployed only when needed

AI summary
An unmanned aerial system for transporting and delivering packages, comprises an unmanned motorized aircraft and a non-motorized aerostatic device having aerostatic lift and being able to be coupled to the motorized aircraft, for transporting at least one package from a take-off site to a delivery site. This aerial system cooperates with a site for storing and distributing aerostatic modules each having a predetermined modular aerostatic lift, the storage and distribution site being located in the vicinity of the take-off site and being configured to deliver a set of j aerostatic modules on demand, which modules are secured by coupling means, so as to supply an aerostatic device with static lift that is substantially greater than or equal to the overall weight of the package to be transported and of the aerostatic device.
