Drone Parachute Deployment Using Thrust and Open-Assist Member
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional parachute devices for drones are limited in reducing the lower critical parachute-opening altitude, making low-altitude cargo delivery unfeasible and restricting the versatility of drone applications due to slow parachute deployment times.
Innovation Solution
The parachute device incorporates an open-assist member that pushes the parachute body at its center, combined with protective shells coated with auxiliary materials to reduce friction, allowing the parachute to deploy quickly and efficiently, with a power source generating thrust to expel the parachute from its container.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If conventional parachute devices are used, then the parachute can be deployed, but the parachute-opening time is too long, making low-altitude cargo delivery unfeasible
Solution Approach 1:
The parachute body is divided into multiple segments or sections that can be deployed in sequence. The container is divided into multiple compartments that can open independently, allowing the parachute to deploy in stages rather than all at once, significantly reducing the overall deployment time while maintaining safety
Solution Approach 2:
The parachute body is pre-positioned and pre-configured within the container in an optimized folded state before deployment. The container is designed with pre-arranged opening mechanisms and the parachute is pre-tensioned, so that when deployment is initiated, the parachute expands rapidly without requiring complex real-time adjustments during the deployment process
2Productivity
If the parachute-opening time is reduced, then low-altitude cargo delivery becomes feasible, but the lower critical parachute-opening altitude must be reduced
Solution Approach 1:
The parachute body is nested within a compact container that is integrated into the drone structure. The container itself is designed to be part of the drone's body or cargo compartment, allowing the parachute to be stored in a space-efficient manner. When deployed, the parachute expands outward from the container, maximizing the use of available space while minimizing the initial deployment altitude required
