Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If each aircraft arm is folded individually to reduce storage space, then the storage compactness is improved, but the operation complexity increases
Solution Approach 1:
The patent combines multiple independent folding operations into a single unified operation through the linkage mechanism. When one aircraft arm is folded, the linkage mechanism automatically drives all other aircraft arms to fold simultaneously, transforming the need for multiple separate operations into a single operation that achieves the same storage compactness.
Solution Approach 2:
The linkage mechanism acts as an intermediary between the operated aircraft arm and the other aircraft arms. By engaging the linkage mechanism's positioning structure with the fuselage body's fixed structure, the system transmits the folding motion from one arm to all other arms through the gear engagement mechanism, eliminating the need to manually operate each arm separately.
2Ease of operation
If multiple aircraft arms are connected through a linkage mechanism, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The linkage mechanism is segmented into modular components: positioning structures on each aircraft arm, gear mechanisms for transmission, and a fixed structure on the fuselage body. This segmentation allows the complex folding function to be achieved through simple, standardized components that can be independently manufactured and assembled, reducing the overall system complexity despite the coordinated motion of multiple arms.
3Ease of operation
If a fixed structure with positioning structure is added to enable linkage folding, then the ease of operation is improved, but the manufacturing complexity increases
Solution Approach 1:
The positioning structure and fixed structure serve multiple functions: they provide the mechanical linkage for coordinated folding, serve as mounting points for the gear mechanisms, and act as structural reinforcement elements. This multi-functionality reduces the need for additional dedicated components, simplifying the manufacturing process while achieving the desired ease of operation.

AI summary
The present invention relates to the technical field of UAV (unmanned aerial vehicle), and more particularly to a UAV with linkage foldable arms, which includes a linkage mechanism, a fuselage body and multiple aircraft arms. The multiple aircraft arms are connected with each other through the linkage mechanism and are connected with the fuselage body; a locating part is located in a middle of the fuselage body; the locating part comprises a positioning structure, a fixed structure which plays a limit role is located on one of the multiple aircraft arms, the fixed structure is buckled with the positioning structure. When the aircraft arms are unfolded or folded, only one aircraft arm needs to be operated to drive other aircraft arms to move under the action of the linkage mechanism, so that multiple folding steps are simplified into a folding process, which is convenient in operation and strong in practicability.
