Drone Load Attachment Member for Posture-Stable Suspended Loads
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aerial vehicles struggle to efficiently suspend a load from an aerial vehicle while also stabilizing the posture of the load.
Innovation Solution
The aerial vehicle is configured to have a body portion with a plurality of rotors and a load attachment member configured to be connected to the body portion, support the load, and adjust the posture of the load.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the load is suspended from the aerial vehicle, then the process of attaching and detaching the load becomes efficient, but the load and wires swing like a pendulum due to downwash, decreasing stability
Solution Approach 1:
A stabilizing member is introduced as an intermediary component between the load and the aerial vehicle. This stabilizing member includes a load receiving portion that supports the load and a posture adjusting portion that actively adjusts the load's posture to counteract swinging caused by downwash, thereby maintaining system stability while keeping the load suspended
Solution Approach 2:
The stabilizing member incorporates dynamic adjustment capabilities through the posture adjusting portion, which can actively change the orientation and position of the load receiving portion in response to downwash forces. This dynamic adjustment prevents the load from swinging like a pendulum while maintaining efficient suspension
2Stability of the object's composition
If the load is fixed to the aerial vehicle, then the stability and control of the aerial vehicle is maintained, but the process of attaching and detaching the load becomes complicated and requires landing
Solution Approach 1:
The load support system is segmented into three functional components: the load itself, the stabilizing member with distinct load receiving portion and posture adjusting portion, and the aerial vehicle. This segmentation allows the load to be independently attached and detached from the stabilizing member while the stabilizing member remains connected to the aerial vehicle, enabling efficient load changes without landing
Solution Approach 2:
The stabilizing member serves as an intermediary that decouples the load attachment/detachment operation from the aerial vehicle connection. The load can be quickly attached or detached from the stabilizing member's load receiving portion while the stabilizing member maintains its connection to the aerial vehicle, thus simplifying the process and improving productivity
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
The load is stabilized by adjusting the posture of the load using the load attachment member, allowing efficient attachment and detachment without landing the vehicle.
Implementation Method 1
the load attachment member adjusts the posture of the load by adjusting a length of at least one of the support members from the body portion to the load attachment member
Implementation Method 2
airflow (downwash) generated by the rotors flows along the inclined portion to the region outward of the load. This suppresses the influence of downwash on the load, and suppresses swinging of the load
Implementation Method 3
the aerial vehicle further includes a posture sensor configured to detect the posture of the load, and the load attachment member adjusts the posture of the load based on a detection result of the posture sensor
