Wing-Flapping Flying Apparatus with Torsional Rotation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wing-flapping flying apparatuses generate lift only during half of the wing-flapping movement, offsetting lift during the other half, leading to unstable flight and requiring larger, heavier designs to compensate for lift deficiencies, and are unable to perform forward, downward, and lateral flights efficiently.
Innovation Solution
A wing-flapping flying apparatus with a rotating shaft and wing parts that undergo torsional rotation, utilizing a combination of stoppers, protrusions, and pins to restrict and reverse the rotational direction of the wings, ensuring lift is generated throughout the entire wing-flapping movement, allowing for precise control of lift and enabling stable, multi-directional flight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If simple upward-and-downward wing movements are used, then the device complexity is reduced, but lift is only generated during half of the wing-flapping movement causing unstable flight
Solution Approach 1:
The patent applies dynamics by enabling the wings to perform torsional rotation in addition to reciprocating motion. The wings are connected to the rotating shaft such that they can rotate about their own longitudinal axes while the shaft rotates, creating a dynamic two-degree-of-freedom motion system that generates lift throughout the entire flapping cycle
Solution Approach 2:
The patent implements periodic action through the rotating shaft that periodically reverses its rotational direction. This periodic reversal drives the wings to perform torsional rotation in alternating directions, ensuring that lift is generated during both the forward and backward strokes of the wing-flapping movement
2Force
If larger wings are used to compensate for lift deficiency, then lift generation is improved, but the weight of the flying object increases
Solution Approach 1:
The patent achieves continuity of useful action by generating lift throughout the entire wing-flapping movement cycle. The combination of reciprocating motion and torsional rotation ensures that the wings are always positioned to generate aerodynamic lift, eliminating the periods of lift offset or loss present in simple flapping mechanisms, thereby reducing the total lift required and allowing for smaller, lighter wings
3Ease of operation
If a mechanism for converting rotatary motion to reciprocating motion is added, then wing flapping is enabled, but the device complexity and weight increase
Solution Approach 1:
The patent merges the reciprocating motion mechanism and torsional rotation mechanism into a unified system. The wings are directly connected to the rotating shaft such that the shaft's rotation simultaneously produces both the reciprocating motion and the torsional rotation, eliminating the need for separate motion conversion mechanisms and reducing overall device complexity
4Device complexity
If simple wing flapping is used, then the structure is simplified, but multi-directional flight control becomes difficult
Solution Approach 1:
The patent applies dynamics by enabling independent control of the rotating shaft's rotational speed and the wings' torsional rotation angle. This dynamic control capability allows the flying object to adjust lift generation and directional movement in real-time, achieving versatile multi-directional flight including upward, downward, forward, and lateral movements without complex control mechanisms

AI summary
The present invention provides a wing-flapping flying apparatus, which can fly by moving its wings similar to a bird hovering or flying in the air by flapping its wings. The wing-flapping flying apparatus comprises: a body; a rotating shaft rotatably joined to the body; driving means for rotating the rotating shaft; and wings reciprocated between two points and connected to the rotating shaft so as to be rotated together with the rotating shaft and to be relatively torsionally rotated with respect to the rotating shaft. The wing-flapping flying apparatus generates lift throughout an entire wing-flapping movement without generating lift only throughout the half of a wing-flapping movement or offsetting the generated lift by the other half of the wing-flapping movement. Therefore, the wing-flapping flying apparatus can provide not only a stable flight but also a softly hovering or ascending and descending flight.
