Drone Payload Drop Mechanism for Contact-Triggered Reusable Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drone payload drop devices require user intervention for payload release and often detach parts like cords or parachutes with the payload, leading to increased costs and waste.
Innovation Solution
A payload delivery and drop device for drones that automatically releases the payload upon contact with a surface without detaching any part of the device or release mechanism, using a moveable collar and rigid bar system to retain and release the payload.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If user control mechanisms (trigger or button) are used for payload release, then the payload can be released on demand, but the device complexity and ease of operation are reduced
Solution Approach 1:
The payload release mechanism automatically activates upon surface contact without requiring user intervention. The impact force from contacting the delivery surface directly triggers the release mechanism, causing the payload to be dropped automatically. This eliminates the need for triggers, buttons, or other user control elements.
2Loss of substance
If traditional attachment mechanisms (drop cords, drop rings) are used, then the payload can be securely attached, but parts are released with the payload leading to increased costs and waste
Solution Approach 1:
The release mechanism is designed to remain attached to the drone while only the payload is released. The mechanism uses a retention structure that holds the payload during delivery, then releases it upon surface contact while the mechanism itself stays on the drone for potential reuse.
Solution Approach 2:
The release mechanism is designed to be reusable and remains attached to the drone after payload release. Only the payload is discarded, while the expensive mechanism with sensors, motors, and control systems is recovered for another delivery mission, reducing overall costs and waste.
3Productivity
If automatic release upon surface contact is implemented, then hands-free delivery is achieved, but the precision of payload release timing may be compromised
Solution Approach 1:
The system is pre-configured with a retention mechanism that holds the payload ready for release. The mechanism is designed to trigger automatically upon surface contact, with the release action built into the contact event itself. This preliminary setup ensures that when the delivery moment arrives, the release occurs precisely and automatically without timing errors.

AI summary
Embodiments of a payload delivery and drop device for an unmanned aerial vehicle, and method of its use are described. An apparatus includes a moveable collar defining a lumen having a centerline, and a rigid bar that has a first portion and a second portion. The first portion of the rigid bar has a centerline and the second portion of the rigid bar has a centerline. The second portion of the rigid bar is disposed within the lumen of the collar when the rigid bar is in a first position. The centerline of the first portion of the rigid bar is substantially non-parallel to the centerline of the lumen of the moveable collar when the rigid bar is in the first position. The centerline of the second portion of the rigid bar is substantially non-parallel to the centerline of the lumen when the rigid bar is in the second position.
