Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional multiple mounting structures are used for various equipment, then each equipment can be securely attached, but aircraft mass increases and manufacturing complexity increases
Solution Approach 1:
The patent combines multiple separate mounting functions into a single integrated attachment structure that serves as a common support for engine components, landing gear, and flight control systems. This consolidation eliminates redundant mounting structures and reduces overall aircraft mass while maintaining secure attachment capabilities for all equipment.
Solution Approach 2:
The attachment structure is designed as a multi-functional component that can simultaneously support various equipment including engine components, landing gear, and flight control systems. This universal structure replaces multiple specialized mountings, reducing complexity and weight while providing reliable attachment points for diverse equipment.
2Reliability
If traditional multiple mounting structures are used for various equipment, then each equipment can be securely attached, but manufacturing complexity increases
Solution Approach 1:
The patent integrates multiple mounting functions into a single attachment structure, reducing the number of separate components that need to be manufactured and assembled. This consolidation simplifies the manufacturing process while ensuring reliable attachment for all equipment through a unified design approach.
Solution Approach 2:
The universal attachment structure provides a standardized platform for mounting various equipment, simplifying manufacturing by using common components and assembly procedures rather than custom solutions for each equipment type.
3Weight of moving object
If a single structural element is used to support multiple systems, then overall mass and design complexity are reduced, but the structure must accommodate various positions and adjustments
Solution Approach 1:
The attachment structure incorporates adjustable mounting positions and movable components that allow adaptation to different equipment configurations. This dynamic design enables the single structural element to accommodate various positions and adjustments while maintaining reduced mass compared to fixed multiple mountings.
Solution Approach 2:
The versatile attachment structure is designed to support multiple types of equipment at various positions through standardized adjustable mounting points, providing the necessary adaptability while maintaining a compact, low-mass design.
4Strength
If traditional attachment structures are used, then structural strength is maintained, but integration of systems like landing gear and flight control systems becomes complicated
Solution Approach 1:
The patent integrates support for landing gear, flight control systems, and engine components into a single attachment structure, simplifying system integration while maintaining structural strength through a unified load-bearing design that handles multiple forces and moments.
Solution Approach 2:
The universal attachment structure provides standardized mounting points and load paths that simplify the integration of various systems, allowing landing gear, flight control systems, and engine components to be mounted on a common structure without compromising strength or increasing complexity.
