Mirrored Aircraft Wing Panel Assembly Line
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current aircraft wing fabrication and assembly processes face inefficiencies due to uneven work density, excessive setup times, and unnecessary movement of components between cells, leading to delays and increased costs.
Innovation Solution
Implementing an assembly line system where wing panels are arranged in mirrored orientations and transported in pulses or continuously, allowing work stations to perform tasks during pauses or while moving, thereby integrating transportation and assembly processes and reducing the frequency of component movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If components are fabricated and assembled in predefined cells on a factory floor, then reliability is maintained, but productivity decreases due to delays when work density is insufficient and excessive movement between cells is required
Solution Approach 1:
The patent implements a dynamic assembly line where wing panels can be continuously moved through multiple work stations rather than being stationary in predefined cells. The assembly line adapts its pace and configuration based on work completion status, allowing components to progress through the assembly process without unnecessary stops or repositioning, thereby maintaining reliability while significantly improving productivity
Solution Approach 2:
The patent applies preliminary action by pre-positioning mirrored wing panels at the assembly line and preparing work stations in advance with required components and tooling. This ensures that when a wing panel arrives at a work station, all necessary assembly activities are ready to proceed immediately, eliminating delays associated with waiting for parts or setup time
2Productivity
If the assembly is advanced to the next cell when work is delayed, then productivity is maintained, but device complexity increases due to requirements for out of position parts, special tooling, and configuration cataloging
Solution Approach 1:
The patent implements universality by designing work stations that can handle multiple types of assembly tasks and accommodate different wing panel configurations. The standardized work stations are equipped with versatile tooling and positioning systems that can adapt to various assembly requirements, eliminating the need for special tooling and out-of-position parts when advancing assemblies through the line
Solution Approach 2:
The patent uses digital modeling and configuration data to create virtual representations of wing panels and their assembly states. This allows the system to track and manage component positions and configurations without physical cataloging, reducing complexity while maintaining productivity through accurate digital twins of the assembly process
3Productivity
If frequent moves between cells are performed, then work density is improved, but loss of time increases due to setup time required at each cell
Solution Approach 1:
The patent implements continuous action by establishing an uninterrupted assembly line where wing panels move continuously through multiple work stations performing different assembly tasks. This eliminates the start-stop nature of cell-based fabrication, maintaining high work density while avoiding repeated setup times by keeping the assembly process in continuous motion from one work station to the next

AI summary
Systems and methods are provided for assembly line processing of aircraft wing panels. The method includes inputting wing panels into an assembly line, the assembly line having a number of work stations, the wing panels oriented such that leading edges are all on a first side of the work stations, and trailing edges are all on a second side of the work stations, and advancing the wing panels in a process direction through the number of work stations, at least a first portion of the work stations dedicated to wing panel leading edge processing, and a second portion of the work stations dedicated to wing panel trailing edge processing.
