Flight Body Frame Assembly for Curvature and Torsion Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing frame assemblies for flight bodies, such as drones and UAVs, suffer from instability due to frame curvature and torsion, which are not adequately addressed by existing technologies.
Innovation Solution
A frame assembly comprising at least two parallel first frame members, a second frame member perpendicular to the first, and fixing members secured to both, with optional reinforcing members and openings for mounting parts, enhancing rigidity and stability.

1Stability of the object's composition
If traditional frame structures are used for flight bodies, then manufacturing is simpler, but frame stability deteriorates due to curvature and torsion
Solution Approach 1:
The frame is divided into multiple straight frame members (first frame members and second frame members) that are segmented and connected through fixing members. This segmentation allows each component to maintain straight geometry while collectively forming a stable three-dimensional structure that resists curvature and torsion.
Solution Approach 2:
The fixing members are positioned within openings of the frame members, creating a nested configuration where fixing members are inserted into and constrained by the frame member openings. This nesting ensures precise alignment and rigid connection between frame members, enhancing overall frame stability.
2Stability of the object's composition
If frame members are made more rigid to reduce curvature and torsion, then frame stability improves, but weight increases
Solution Approach 1:
Instead of making individual frame members excessively rigid, the structure segments the frame into multiple straight members connected by fixing members. This distributes the structural load across multiple components, allowing each member to be lighter while maintaining overall frame stability through the collective rigid connection of segments.
Solution Approach 2:
The frame structure transitions from planar arrangements to three-dimensional configurations by vertically arranging frame members and fixing members at different heights. This spatial distribution in multiple dimensions enhances structural rigidity and stability without requiring increased material thickness or weight in individual components.

AI summary
To stabilize a frame of a flight body, a frame assembly for a flying body includes a first frame member extending in at least two parallel and first directions, a second frame member extending in a second direction perpendicular to said first direction, and a fixing member fixed to each of the first and second frame members, wherein at least one of the fixing members has an opening.
