Movable Rotor Arm Layout for Unobstructed Aerial Imaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aerial vehicles face issues with the load assembly being obstructed by the power device, limiting the operational space and functionality of onboard equipment such as cameras and sensors in near-ground environments.
Innovation Solution
The aerial vehicle design includes arm assemblies that can move relative to the center body, allowing the distal parts to adjust between two height positions, altering the spacing of rotor power assemblies to create unobstructed operational space for load assemblies, enabling 360° yaw and upward photographing modes without interference from the power device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the power device is installed on the aerial vehicle, then the aerial vehicle can perform flight operations, but the load assembly is obstructed by the power device, limiting operational space
Solution Approach 1:
The arm assemblies are designed to be movable relative to the center body, allowing the distal parts to adjust between two height positions. This dynamic configuration enables the spacing between rotor power assemblies to change, creating unobstructed operational space for the load assembly during photography operations while maintaining flight capability.
2Adaptability or versatility
If the arm assemblies are designed to move between two height positions, then unobstructed operational space is created for load assemblies, but the device complexity increases
Solution Approach 1:
The aerial vehicle is divided into modular components: a center body, two movable arm assemblies with proximal and distal parts, and a driver mechanism. This segmentation allows independent movement and positioning of the arm assemblies, enabling versatile photography modes including 360° yaw and upward photography while keeping each component relatively simple in design.
3Ease of operation
If the spacing between first rotor power assemblies is increased, then operational space for load assembly is improved, but the spacing between second rotor power assemblies decreases
Solution Approach 1:
The arm assemblies are positioned asymmetrically with respect to the rotor power assemblies. The first rotor power assemblies are located closer to the installation site for the load assembly, while the second rotor power assemblies are positioned farther away. This local differentiation allows the spacing between first rotor power assemblies to be increased for better operational space without significantly affecting the spacing between second rotor power assemblies.

AI summary
An aerial vehicle includes a center body, two arm assemblies arranged at the center body, a power device, and a driver mechanism mechanically coupled to the arm assemblies. The power device includes two first and two second rotor power assemblies. Each pair of first and second rotor power assemblies are installed at two ends of an arm assembly. The driver mechanism drives the arm assemblies to move relative to the center body such that distal parts of the two arm assemblies move between first and second height positions. In a direction of a roll axis of the power device, the first rotor power assemblies are closer to an installation site on the center body than the second rotor power assemblies. When the distal parts are at the second height position, spacing between the first rotor power assemblies is larger than spacing between the second rotor power assemblies.
