Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If multiple components are used in the leading edge movable device, then structural integrity can be maintained, but airflow turbulence increases and aerodynamic performance deteriorates
Solution Approach 1:
The patent merges multiple components into a single integrated trailing edge component that connects the top skin and back skin. This one-piece construction eliminates the need for separate fasteners and connecting elements, thereby reducing airflow disturbances while maintaining structural integrity through the unified design.
2Reliability
If multiple fasteners are used near the leading edge, then component connection is secured, but aerodynamic efficiency decreases
Solution Approach 1:
The patent integrates the connection function into a single trailing edge component that spans from the leading edge to the trailing edge of the movable device. This eliminates the need for multiple fasteners near the leading edge, reducing aerodynamic interference while maintaining reliable component connection through the integrated structure.
Solution Approach 2:
The patent extracts and eliminates the fasteners from the leading edge region by incorporating their connection function into the trailing edge component. This removal of disturbing elements (fasteners) from the critical airflow region improves aerodynamic efficiency while the connection function is preserved through the integrated design.
3Stability of the object's composition
If multiple parts are joined together, then structural completeness is achieved, but manufacturing complexity increases
Solution Approach 1:
The patent combines multiple parts into a single trailing edge component that integrates the connection between top skin and back skin. This merging reduces the number of assembly steps and fastening operations required, thereby simplifying manufacturing while achieving structural completeness through the unified component design.
