Drone Parachute Kit with Battery Detector and Pressurizer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional drones often crash when power is cut off, leading to breakage and potential human or property damage, and existing parachute systems fail to deploy properly or evenly, especially under unexpected power loss due to factors like lightning or electromagnetic pulses.
Innovation Solution
A drone system equipped with a parachute kit that includes a battery detector, controller, and pressurizer using spring elasticity or compressed air to unfold a parachute when power is exhausted, ensuring safe landing by connecting the parachute to multiple points via wires and measuring altitude and position for optimal deployment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a parachute system is equipped with complex deployment mechanisms to ensure reliable opening, then parachute deployment reliability is improved, but device complexity and weight increase
Solution Approach 1:
The parachute system is divided into multiple independent components: parachute cover, parachute body, deployment wires, spring mechanism, and compressed air chamber. Each component performs a specific function, and the segmentation allows the system to achieve reliable deployment through coordinated action of simple individual parts rather than a single complex mechanism.
Solution Approach 2:
The spring is pre-compressed and the compressed air is pre-stored in the chamber before deployment is needed. When power is lost or parachute deployment is commanded, these pre-stored energy sources immediately activate the deployment sequence without requiring real-time power or complex control, ensuring reliable operation under emergency conditions.
2Ease of operation
If a parachute is deployed using only battery power, then deployment control is simple, but the system fails when battery power is unexpectedly lost due to lightning or electromagnetic pulses
Solution Approach 1:
The system incorporates emergency energy storage mechanisms (compressed spring and compressed air chamber) that are prepared in advance specifically to cushion against the harmful effect of unexpected power loss. These mechanisms ensure that even if battery power is lost due to lightning or electromagnetic pulses, the parachute can still be deployed reliably using the pre-stored mechanical energy.
Solution Approach 2:
The spring and compressed air act as intermediary energy storage devices between the electrical control system and the parachute deployment mechanism. When power is available, the system operates normally; when power is lost, the intermediary mechanical energy sources take over to ensure deployment, bridging the gap between electrical control and mechanical action.
3Device complexity
If the parachute is connected to single point on the drone, then the connection structure is simple, but the parachute does not spread evenly causing unsafe landing
Solution Approach 1:
The parachute connection system is segmented into multiple connection points distributed across the drone body rather than a single central connection. Multiple deployment wires connect the parachute to different locations, allowing the parachute canopy to expand uniformly in all directions and achieve even spreading for safe landing.
4Reliability
If a parachute kit is permanently integrated into the drone, then deployment reliability is improved, but the drone weight increases and adaptability decreases
Solution Approach 1:
The parachute kit is designed with detachable coupling mechanisms that allow it to be dynamically attached or detached from the drone based on operational needs. This dynamic configuration enables the system to have the parachute integrated during flights where safety is prioritized, and detached when weight reduction or adaptability is needed, resolving the contradiction between reliability and weight/adaptability.
