Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the wing and fuselage are integrally designed and manufactured, then the structural stability and center of gravity control are improved, but the development cost and design flexibility deteriorate
Solution Approach 1:
The aircraft is divided into separate functional modules: a fuselage module and a wing module, which can be independently designed, manufactured, and assembled. This segmentation allows different teams to work on different modules simultaneously, reducing overall development time and cost while maintaining structural integrity through standardized connection interfaces.
Solution Approach 2:
The fuselage module is designed as a universal platform that can accommodate multiple different wing configurations. The standardized connection interface between fuselage and wing allows for easy reconfiguration and swapping of wing modules, enabling a single fuselage design to support multiple aircraft variants without requiring complete redesign.
2Reliability
If the wing and fuselage are integrally designed and manufactured, then the connection boundary hydrodynamics are optimized, but the manufacturing flexibility and component reusability deteriorate
Solution Approach 1:
The connection boundary between fuselage and wing is designed with dynamic adjustment capabilities, allowing for optimized aerodynamic performance during flight while maintaining mechanical flexibility for assembly and disassembly. The connection interface incorporates adjustable elements that can be tuned for different flight conditions while preserving manufacturing flexibility.
3Stability of the object's composition
If traditional aircraft structures are used for aerial takeoff and landing, then the stabilization is achieved, but the shock absorption capability deteriorates
Solution Approach 1:
The connection structure between fuselage and wing incorporates built-in shock absorption mechanisms that are activated before impact occurs during aerial takeoff and landing. Energy-absorbing elements such as springs, dampers, or deformable structures are pre-positioned in the connection interface to cushion external shocks before they can damage critical components.
4Stability of the object's composition
If additional stabilization structures such as tail wings are added, then the flight stability is improved, but the device complexity and development cost deteriorate
Solution Approach 1:
The stabilization function is merged into the main wing structure itself, eliminating the need for separate tail wing components. The wing design incorporates inherent stability characteristics through its geometry, mass distribution, and connection to the fuselage, allowing a single integrated structure to perform both lift generation and flight stabilization functions.

AI summary
The flight machinery includes a structure in which a main body and a lightweight wing having an unvalued weight compared with the main body are connected by use of a power joint on a line joining the center of a lift force and the center of gravity of the wing in the manner that the main body is positioned under the wing. Accordingly, it is possible to exhibit a function of the flight machinery by adjusting the power joint connecting the upper part and the lower part or the wing to the main body even if the wing and the main body have different characteristics. Additionally, it is possible to stabilize a posture by positioning the total center of gravity at the main body at the lower part. At the same time, it is possible to stabilize the posture just by controlling the position of the servomotor of the power joint.
