UAV Parcel Delivery Rail System for Load-Balance Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current UAV parcel delivery systems struggle to adjust for changes in load conditions, such as changes in center-of-gravity, due to the pickup or delivery of parcels, which can affect the stability and efficiency of the UAV.
Innovation Solution
A parcel delivery system for UAVs that includes a rail system coupled with a drive system, allowing parcel carriers to be translated relative to the UAV, adjusting their position to maintain stability and efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If parcels are picked up or delivered by the UAV, then the cargo location needs to be adjusted to maintain stability, but the device complexity increases due to the rail system and drive system
Solution Approach 1:
The parcel carrier is made movable along the rail system, allowing dynamic adjustment of cargo position relative to the UAV body. The drive system enables the parcel carrier to translate to different locations based on load conditions, transforming a static cargo mounting system into a dynamic one that can adapt to changing center of gravity requirements.
Solution Approach 2:
The cargo transport system is segmented into modular components: the rail system attached to the UAV body, the movable parcel carrier, and the drive system. This segmentation allows independent optimization of each component and enables flexible reconfiguration of cargo position without redesigning the entire UAV structure.
2Reliability
If the UAV remains at a safe distance above the surface, then safety is improved and more locations are accessible, but the precision of parcel delivery is reduced
Solution Approach 1:
The system uses dynamic position adjustment of the parcel carrier along the rail to compensate for the increased delivery distance. By moving the cargo to optimized positions on the rail system, the UAV can maintain safe altitudes while improving delivery precision through mechanical positioning rather than relying solely on aerial proximity.
Solution Approach 2:
The rail system acts as an intermediary mechanism between the UAV body and the parcel carrier. It provides a controlled interface for adjusting cargo position, enabling precise parcel placement even when the UAV maintains a safe distance from the delivery location.

AI summary
A multiple hoist system is used with an unmanned aerial vehicle (UAV) for delivering parcels. An example of the multiple hoist system comprises two or more hoists that are independently operable, meaning that a first hoist can lower or raise a first line independently of using a second hoist to raise or lower a second line. The hoists can independently raise and lower their associated lines to allow the UAV to deliver multiple parcels to multiple delivery locations, or the hoists can synchronously raise and lower the associated lines together so that larger parcels can be delivered using the UAV. The hoists can be comprised within a body of the multiple hoist system. The body can further include a securing device for releasably securing the multiple hoist system to the UAV.
