Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the rotor assembly is fixedly connected to the main body, then the structure is simple and stable, but the flying machine cannot change shape and has monotonous flight mode
Solution Approach 1:
The lift system is designed with rotatable connections between the main body and the rotor assembly, allowing the structure to dynamically change its configuration. The transmission member enables the lift system to rotate between a first position (first shape), a second position (second shape), and a third position (third shape), transforming a static structure into a dynamic one that can adapt its form during flight.
Solution Approach 2:
The flying machine is divided into separable functional modules: the main body, the lift system with rotor assembly, the transmission member, and the drive mechanism. This segmentation allows independent movement and positioning of the lift system relative to the main body, enabling shape transformation while maintaining structural integrity through standardized connection interfaces.
2Adaptability or versatility
If the lift system is fixed in position, then the control system is simple, but the flight mode is monotonous and lacks interest
Solution Approach 1:
The drive mechanism automatically controls the transmission member to move between different positions based on pre-set patterns or user input, enabling the lift system to autonomously transform between shapes. This self-service capability provides varied flight modes without requiring complex manual control inputs from the user.
Solution Approach 2:
The transmission member can be driven to move periodically between different positions, creating rhythmic shape transformations that enable dancing flight modes. The periodic movement between the first position, second position, and third position generates visually appealing patterns that enhance flight entertainment value.
3Adaptability or versatility
If multiple transmission positions are added for shape transformation, then the flight becomes more interesting, but the positioning precision requirement increases
Solution Approach 1:
The transmission member acts as an intermediary component that translates the rotational movement from the drive mechanism into precise positional changes of the lift system. By using a dedicated transmission member with defined engagement positions, the system achieves accurate positioning without requiring extremely tight manufacturing tolerances across all components.
Solution Approach 2:
The system incorporates positioning features and stop mechanisms that pre-establish the first position, second position, and third position for the transmission member. These pre-defined positions provide mechanical guidance and cushioning that compensate for accumulated manufacturing tolerances, ensuring reliable positioning without requiring ultra-precise manufacturing.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The transformable flying machine enhances user engagement by allowing for visually appealing and interactive flight maneuvers, including in-place dancing and aerial dancing, providing a more interesting flying experience.
Implementation Method 1
a magnetic component is arranged on the transmission member; the driving member includes two electromagnets arranged on the main body... upon one of the electromagnets being energized, the one of the electromagnets attracts the magnetic component, causing the transmission member to move
Implementation Method 2
the elastic limit member includes a first elastic arm and a second elastic arm; in the state where the transmission member moves to the first position, the first elastic arm is in an elastic deformation state

AI summary
A transformable flying machine, including: a main body, a drive mechanism, and two lift system sets. The two lift system sets are arranged on both sides of the main body, and both the two lift system sets are rotatably connected to the main body. The drive mechanism is arranged on the main body, and the drive mechanism includes a driving member and a transmission member; the transmission member is rotatably connected to the two lift system sets, and the driving member is configured to drive the transmission member to move along a direction of a connecting line of centers of the two lift system sets, so as to drive the two lift system sets to rotate, for adjusting a tilt angle of the two lift system sets relative to the main body.
