Suspended-Load Aerial Vehicle Support Structure for Airframe Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aerial vehicles face challenges in controlling stability and accuracy when suspending a load due to the influence of load configuration, weight distribution, and external disturbances such as wind.
Innovation Solution
The aerial vehicle is configured with a lift-generating section, support members, and a relay section, where one of the attachment or relay sections is disposed outward in the airframe to balance weight, reducing instability and enhancing stability, while motors are housed in a central region for unitization and protection, and pulleys are used to reduce friction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple attachment sections and winding sections are provided in an outer region of the airframe to suspend a load, then the load suspension capability is improved, but the weight of the outer side of the airframe increases making the airframe unstable
Solution Approach 1:
The patent transitions from a two-dimensional planar arrangement to a three-dimensional spatial arrangement by disposing attachment sections and winding sections at different vertical levels (heights). The attachment section is positioned at a first height while the winding section is positioned at a second height different from the first, creating a vertical dimension that separates their horizontal projections. This dimensional change allows both components to coexist in the outer region without concentrating weight at the same location, thereby maintaining airframe stability while preserving load suspension capability.
2Ease of operation
If the attachment section and winding section are disposed in the outer region of the airframe, then the load can be suspended from outside the airframe, but the weight distribution becomes unbalanced reducing control accuracy
Solution Approach 1:
The patent employs vertical separation to resolve the weight distribution problem. By positioning the attachment section at a first height and the winding section at a second height, the horizontal projections of these components are separated in the plan view. This vertical arrangement allows the load to be suspended from the outer region while distributing weight vertically, preventing horizontal weight imbalance and maintaining control accuracy.
3Stability of the object's composition
If the attachment section is positioned outward of the winding section, then the weight balance of the airframe is improved, but the structural complexity increases
Solution Approach 1:
The patent resolves the contradiction by utilizing the vertical dimension to separate the attachment section and winding section. The attachment section is disposed at a first height while the winding section is disposed at a second height, causing their horizontal projections to be separated in the plan view. This vertical arrangement achieves weight balance improvement without requiring complex horizontal structural modifications, as the separation is accomplished through simple vertical positioning of existing components.

AI summary
An aerial vehicle configured to fly with a load 8 suspended therefrom includes: a lift-generating section 3 configured to generate lift for flight; a plurality of support members 5 configured to support the load 8; an attachment section 16 to which the support members 5 are attached; and a relay section 17 relaying and supporting the support members 5 between the load 8 and the attachment section 16. One of the attachment section 16 and the relay section 17 is disposed outward, in an airframe of the aerial vehicle, of another one of the attachment section 16 and the relay section 17 in a plan view.
