Aerial Winch Payload Delivery System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current drone package delivery methods face challenges such as low accuracy, noise, visual impact, collision risks, and privacy concerns due to hovering at low levels, and require additional delivery methods for precise location delivery.
Innovation Solution
A system utilizing a winch mechanism with a hauling means on-board a device suspended from an aerial platform, allowing controlled vertical movement and positioning of payloads via a line, enabling precise delivery and collection while minimizing noise and visual impact, and allowing the aerial platform to remain at a safe height.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the drone hovers at a low level to deliver packages using a winch, then the package delivery can be completed, but this creates local noise, visual impact, privacy concerns, and increases the risk of collisions with nearby objects
Solution Approach 1:
The patent transitions the delivery operation from the horizontal plane (low-level hovering near ground obstacles) to the vertical dimension (high-altitude positioning with line-based payload descent). The aerial platform maintains position at elevated altitudes while payloads are delivered vertically along lines, separating the delivery function from ground-level spatial constraints and harmful interactions.
Solution Approach 2:
The system separates the aerial platform from the payload delivery mechanism by using detachable lines. The platform performs high-altitude positioning while the payload is independently lowered along the line to the delivery point. This segmentation allows the platform to remain in a safe, high-position while completing precise deliveries without ground-level hazards.
2Ease of operation
If the drone lands to deliver packages, then the delivery can be completed, but this generates a lot of noise, has a high visual impact, and increases the risk of collisions with nearby objects or people
Solution Approach 1:
The patent extracts the payload delivery function from the aerial platform itself by using a line-based lowering mechanism. Instead of the platform landing to deliver, the payload is separated and lowered along the line to the delivery location. This extraction eliminates the need for ground contact, removing the associated noise, visual impact, and collision risks of landing operations.
3Productivity
If the drone uses an unguided parachute for package delivery, then the delivery can be completed, but this suffers from low accuracy and presents a high safety risk due to an inability to abort a delivery
Solution Approach 1:
The system incorporates guidance and control mechanisms that provide feedback during payload descent along the line. Unlike unguided parachutes, the line-based system allows for controlled lowering with the ability to adjust descent rate and position, enabling accurate delivery to specific locations and providing safety abort capabilities through active control.
4Productivity
If the drone uses a specially designed location, vehicle, structure and/or locker for package delivery, then the delivery can be completed, but this generates inconvenience for the customer to collect or requires an additional delivery method to take the package to the destination
Solution Approach 1:
The line acts as an intermediary mechanism that directly connects the aerial platform to the delivery location. This eliminates the need for intermediate structures, vehicles, or lockers by providing a direct delivery path from the platform to the customer's location, enabling convenient doorstep delivery without requiring customer travel to collection points.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables safe, precise, and efficient delivery and collection of packages with reduced noise and visual impact, increased safety, and extended range, allowing the aerial platform to remain at a higher altitude, reducing vulnerability to ground obstacles and improving delivery tempo.
Implementation Method 1
a winch provided on-board the device at or towards a bottom, payload end of the line
Implementation Method 2
The winch may be associated with or provided on, by or in the region of a payload/package. The winch system may include a kinetic energy recovery system operable, for example, as the winch slows down.
