Rotatable Release Mechanism for Drone Payload Transport
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for transporting and releasing objects, such as drones, are complex in construction and operation, making it difficult to attach and release objects, and lack a mechanism to safely release objects that become trapped or tangled.
Innovation Solution
A rotatable release mechanism with a wheel connected to a servo/mechanical/electrical device, featuring a slot and finger design for easy attachment and release, and a magnetic release member for fail-safe disconnection, controlled by sensors and an activation unit for automatic or manual operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a complex attachment mechanism is used to securely transport objects, then the reliability of object transport is improved, but the ease of operation deteriorates
Solution Approach 1:
The wheel is segmented with a slot that creates a finger structure, allowing the connecting device to be easily inserted and secured. The slot divides the wheel structure to create a simple yet effective retention mechanism that guides the connecting device into place while maintaining secure transport.
Solution Approach 2:
A connecting device with barrel swivel assemblies acts as an intermediary between the wheel and the object. This connecting device simplifies the attachment process by providing a standardized interface that easily engages with the wheel's slot and finger structure, reducing operational complexity.
2Reliability
If a secure release mechanism is used to prevent premature release, then the reliability is improved, but the device complexity increases
Solution Approach 1:
The release mechanism uses a dynamic rotational motion of the wheel to trigger release. As the wheel rotates, the finger moves along a predetermined path that automatically disengages the connecting device from the slot, providing a simple yet reliable release action without complex mechanisms.
Solution Approach 2:
The slot and finger structure is designed to automatically engage and disengage the connecting device based on wheel rotation. The geometry of the slot and finger creates a self-actuating mechanism that secures the object during transport and automatically releases it when the wheel rotates to a specific position, eliminating the need for additional release components.
3Device complexity
If no release mechanism is provided, then the device complexity is reduced, but the object-generated harmful factors increase due to tangling
Solution Approach 1:
The rotational movement of the wheel serves a dual function: it secures the connecting device during transport and automatically releases it when needed. The dynamic rotation causes the finger to move along the slot and disengage the connecting device, preventing tangling and damage without requiring a separate release mechanism.
Solution Approach 2:
The slot structure extracts the retention function from a complex locking mechanism and integrates it into the wheel's basic geometry. The finger extending from the slot provides the necessary retention and release capability through simple rotational movement, eliminating the need for additional release components while preventing harmful tangling effects.

AI summary
A rotatable release mechanism mounted to an output shaft of a servo/mechanical device and connected to a transport device. The mechanism has at least one wheel with at least one opening that is in communication with a slot that extends to an outer perimeter of the wheel. The opening receives and retains a connecting device during transport and releases the connecting device upon rotation of the release mechanism.
