Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional aircraft attachment structures, such as pylons, increase aircraft mass and manufacturing complexity when multiple systems are attached, and do not efficiently accommodate adjustability and integration of various components.
Innovation Solution
A multi-purpose aircraft attachment structure that integrates a structural member, pylon, and landing gear system, allowing for adjustable mounting of flight control systems and landing gear, with a design that reduces overall design complexity and mass by using a pivotally attached boom and wing connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional pylons are used to attach multiple systems, then the aircraft can support various components, but the aircraft mass increases and manufacturing complexity increases
Solution Approach 1:
The patent combines multiple attachment functions into a single integrated pylon structure. The pylon integrates engine mounting, landing gear attachment, and flight control surface connections into one consolidated structure, eliminating the need for separate attachment structures for each system and thereby reducing overall aircraft mass.
Solution Approach 2:
The pylon is designed as a multi-functional attachment structure that can simultaneously support engine components, landing gear, and flight control surfaces. This universal design allows a single structure to perform multiple attachment functions that would traditionally require separate structures, reducing the overall mass and complexity of the aircraft.
2Adaptability or versatility
If traditional pylons are used to attach multiple systems, then the aircraft can support various components, but the manufacturing complexity increases
Solution Approach 1:
The patent consolidates multiple attachment functions into a single integrated pylon structure. By merging engine mounting, landing gear attachment, and flight control surface connections into one structure, the design reduces the number of separate components that need to be manufactured and assembled, thereby reducing manufacturing complexity.
3Strength
If the attachment structure is rigidly secured, then the structural strength is high, but the adjustability and accommodation of manufacturing deviations are reduced
Solution Approach 1:
The patent incorporates adjustable mounting mechanisms within the pylon structure that allow for position adjustments to accommodate manufacturing deviations. These mechanisms maintain structural integrity while providing the flexibility to adjust component positions, thereby balancing strength requirements with adaptability needs.
4Reliability
If multiple separate attachment structures are used, then each component can be optimized independently, but the overall aircraft mass and design complexity increase
Solution Approach 1:
The patent merges multiple attachment functions into a single integrated pylon structure that maintains the ability to optimize each component independently through modular design elements within the unified structure, thereby achieving reliability without the penalty of increased mass from multiple separate structures.
