Thrust Inverter Boom Connecting Cup Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing thrust reverser structures require time-consuming assembly/disassembly operations and are heavy due to the large number of fasteners needed, which is undesirable in the aeronautical field where weight adds significant cost.
Innovation Solution
The integration of a connecting cup into each beam of the thrust reverser structure allows direct fitting and fixing with the front half-frame, eliminating the need for spacers and fastening elements, thereby reducing the number of components, assembly time, and weight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If spacers and fasteners are used to connect beams to front half-frame, then the structural connection is achieved, but the assembly/disassembly time increases and the mass increases
Solution Approach 1:
The patent merges the spacer and fastener functions into a single integrated connecting element that is fixed to the beam. This combining of components eliminates the need for separate spacers and multiple fasteners, thereby reducing assembly/disassembly operations and time while maintaining structural connection reliability.
Solution Approach 2:
The connecting element is designed as a segmented structure with specific portions fixed to the beam and other portions engaging with the front half-frame. This segmentation allows the single element to perform multiple functions (positioning, spacing, and fastening) that previously required separate components.
2Reliability
If spacers and fasteners are used to connect beams to front half-frame, then the structural connection is achieved, but the number of components increases and manufacturing cost increases
Solution Approach 1:
The patent combines multiple discrete components (spacers and fasteners) into a single integrated connecting element. This reduction in component count simplifies the device structure, reduces manufacturing complexity, and lowers production costs while maintaining the necessary structural connection.
3Reliability
If spacers and fasteners are used to connect beams to front half-frame, then the structural connection is achieved, but the mass of the assembly increases
Solution Approach 1:
By merging the spacer and fastener functions into a single connecting element, the total mass of fastening components is reduced. The integrated design eliminates redundant material from multiple separate parts while maintaining the structural strength and connection reliability required for the thrust reverser assembly.
