Single-Use Lowering Line for Drone Package Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current aerial vehicle package delivery systems face challenges in efficiently coupling and releasing lines after package delivery, as they often require spooling back the cable, which is inefficient and lacks a mechanism for detaching the line from the vehicle at the delivery location.
Innovation Solution
A package deployment system featuring a spool, a lowering line with a cutting device, and a monitoring system that allows for precise severing of the line based on predetermined parameters, enabling the line to be detached from the aerial vehicle and left with the package, with options for spooling the line back or using a parachute for controlled descent.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the cable is spooled back after package delivery, then the aerial vehicle can reuse the cable for subsequent deliveries, but the operational complexity increases and time is lost during the spooling process
Solution Approach 1:
The lowering line is divided into two separate portions: a first portion that remains on the spool at the aerial vehicle and a second portion that is detached and left with the package. This segmentation eliminates the need to spool back the entire line, reducing operational complexity while maintaining productivity.
Solution Approach 2:
The cutting device severs the lowering line to extract and remove the second portion from the system at the delivery location. This extraction allows the aerial vehicle to retain only the necessary first portion on the spool, eliminating unnecessary spooling operations and reducing operational complexity.
2Ease of operation
If the lowering line is detached from the aerial vehicle at the delivery location, then delivery precision is improved and operational complexity is reduced, but the line cannot be reused for subsequent deliveries
Solution Approach 1:
The lowering line is segmented into a reusable first portion that remains on the aerial vehicle and a disposable second portion that is detached with the package. This segmentation enables both operational simplicity and cable reuse capability to coexist.
Solution Approach 2:
The system discards the second portion of the lowering line with the package while recovering and retaining the first portion on the spool for future use. This selective discarding and recovering approach optimizes both operational simplicity and resource utilization.
3Manufacturing precision
If a cutting device is added to sever the lowering line, then the line can be detached cleanly at the delivery location, but the device complexity increases
Solution Approach 1:
The cutting device is integrated into the package deployment system to extract and sever the lowering line at a precise location. This extraction of the cutting function enables clean detachment at the delivery location, improving delivery precision despite the added component.
Solution Approach 2:
The cutting device acts as an intermediary mechanism between the spool and the package, enabling precise separation of the lowering line portions. This intermediary component facilitates clean detachment while maintaining overall system manageability.
