Multiple Hoist UAV Delivery for Multi-Location Parcel Drops
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current UAV parcel delivery systems are limited to delivering a single parcel or group of parcels to a single location due to having only one line, requiring the UAV to return to a loading point after each delivery.
Innovation Solution
A multiple hoist system with independently operable hoists allows for multiple parcels to be loaded and delivered to multiple locations, with the option for synchronous or asynchronous line operation, and includes a securing device for easy attachment to UAVs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If only one line is used in the UAV delivery system, then the system structure is simple, but the system can only deliver a single parcel or one group of parcels to a single location, reducing productivity
Solution Approach 1:
The single line system is segmented into multiple independent lines (first line, second line, etc.), each capable of delivering parcels independently. This allows the UAV to deliver multiple parcels to different locations simultaneously, significantly improving productivity while maintaining manageable system complexity through modular design
2Productivity
If the UAV returns to a loading point after each delivery, then the system structure remains simple with one line, but time is lost during return trips, reducing productivity
Solution Approach 1:
By dividing the delivery system into multiple independent lines, the UAV can deliver parcels along different routes simultaneously without needing to return to a single loading point for each delivery. This parallel delivery capability eliminates idle return trip time and significantly improves delivery efficiency
Solution Approach 2:
The multiple line system enables continuous delivery operations where the UAV can maintain useful action throughout the flight by delivering parcels along multiple lines simultaneously, rather than having idle time during return trips to a single loading point
3Productivity
If multiple hoists are added to enable multiple parcel delivery, then productivity increases, but the weight of the moving object increases
Solution Approach 1:
The delivery system is segmented into multiple independent hoist units, each with its own line. This modular approach allows the UAV to deliver multiple parcels simultaneously, improving productivity. The segmented design also enables flexible configuration to balance payload capacity with weight constraints

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.
