Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If a fixed-wing structure is adopted, then the structure is simple and stable, but the navigation or flight speed is low and maneuverability is poor
Solution Approach 1:
The patent applies the dynamics principle by transforming the fixed wing structure into a morphing wing structure that can dynamically change its airfoil profile, pitch angle, and other geometric parameters. The multi-connecting-rod mechanism with motors enables real-time adjustment of the wing's shape and configuration to adapt to varying flight conditions, thereby improving navigation speed and maneuverability while maintaining structural integrity.
2Adaptability or versatility
If a limited morphing wing structure is adopted, then the structure can adjust to some extent, but it cannot adapt to complex flow fields or environments, resulting in low efficiency and poor stability
Solution Approach 1:
The patent applies segmentation by dividing the wing structure into multiple independent controllable segments through the multi-connecting-rod mechanism. Each segment can be adjusted independently to optimize performance in specific flight conditions. The segmentation allows the wing to adapt to complex flow fields by adjusting individual sections while maintaining overall structural stability through the coordinated action of multiple rods and motors.
Solution Approach 2:
The patent applies parameter changes by enabling continuous adjustment of critical geometric parameters including airfoil profile, pitch angle, and wing shape. The multi-connecting-rod mechanism with motors facilitates real-time modification of these parameters to match varying flight environments, improving both adaptability and stability by optimizing the wing's interaction with complex flow fields.
3Ease of operation
If a fixed or limited morphing wing structure is used, then the device is simpler, but high maneuverability cannot be achieved
Solution Approach 1:
The patent applies dynamics by implementing a fully movable morphing wing structure that can rapidly change its configuration in response to control inputs. The multi-connecting-rod mechanism with motors enables dynamic adjustment of the wing's airfoil profile, pitch angle, and other parameters, allowing the vehicle to achieve high maneuverability by adapting the wing shape to various flight phases and maneuver requirements.
