Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the rotary wing is designed with a fixed configuration, then the drone can maintain stable flight performance, but the drone occupies significant space and is inconvenient for carrying and storage
Solution Approach 1:
The patent applies the dynamics principle by making the rotary wing module movable rather than fixed. The rotary wing module can rotate between a horizontal flight position and a vertical storage position around an articulating shaft. This dynamic configuration allows the drone to maintain stable flight when the wings are horizontal and reduces storage space when folded vertical, resolving the contradiction between flight stability and storage compactness.
2Volume of moving object
If the rotary wing module is made foldable to improve portability, then the storage space is reduced, but the structural complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the drone into distinct functional modules: the drone body and the rotary wing module. The rotary wing module is further segmented into left and right wings that can independently rotate. This modular segmentation simplifies the overall structure by allowing each module to be optimized independently, reducing the complexity burden despite the added articulation mechanism.
Solution Approach 2:
The patent applies the nesting principle by positioning the articulating shaft and control mechanisms within the drone body, and nesting the left and right rotary wings within the rotary wing module. When folded, the wings nest vertically alongside the drone body, creating a compact integrated structure that minimizes external complexity while maintaining internal functionality.
3Ease of operation
If the rotary wing module is articulated to allow folding, then the portability is improved, but the control system complexity increases
Solution Approach 1:
The patent applies self-service by implementing an automatic control system that autonomously manages the articulation of the rotary wing module. The control system automatically transitions the wings between horizontal and vertical positions based on flight state detection, eliminating the need for manual operation. This automation improves portability through easy folding while managing control complexity through intelligent autonomous control rather than complex mechanical linkages.

AI summary
A foldable unmanned aerial vehicle for improving the portability of unmanned aerial vehicles comprises an unmanned aerial vehicle body (1) and a rotor portion connected to the unmanned aerial vehicle body (1). The rotor portion comprises a first rotor module (2) and a second rotor module (3) each having at least one rotor. The first rotor module and the second rotor module can be folded or unfolded by rotation around their own hinge shafts (4). According to the unmanned aerial vehicle, the rotor is designed in a modular manner: first, two rotor modules that can be folded or unfolded relatively are formed, and the folding and unfolding are implemented by the rotation of the rotor modules, so that the state of the unmanned aerial vehicle is changed, the folding and flying demands for the unmanned aerial vehicle are satisfied, and the portability of the unmanned aerial vehicle is improved; a flight path and a control module that the unmanned aerial vehicle needs can be arranged in the unmanned aerial vehicle body and do not need to be separately arranged in the rotor modules, so that the control reliability is improved.
