Aircraft Component Assembly Gap Adjustment Without Shims
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for assembling aircraft components, such as the fuselage and wings, are complicated due to the need for measuring gaps, manufacturing shims, and inserting them, which increases the complexity of the assembly operation.
Innovation Solution
An assembling device comprising a holding member and a processing device that adjusts excess thickness portions on the assembly components to align and integrate them precisely, eliminating the need for shim insertion by performing non-contact processing to match ideal assembly shapes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If shims are manufactured and inserted to fill gaps between assembly components, then the gap filling is achieved, but the assembly operation complexity increases
Solution Approach 1:
The invention extracts and removes the excess thickness portions from assembly components using a processing device, eliminating the need for separate shim manufacturing and insertion operations. The processing device directly removes material to achieve the desired gap, simplifying the assembly process while maintaining precision.
Solution Approach 2:
The assembly components themselves serve the function of gap adjustment through their excess thickness portions. By processing these portions directly on the components, the system eliminates the need for separate shim components, making the components self-sufficient for gap management.
2Manufacturing precision
If multiple steps (measurement, manufacturing, insertion) are used to fill gaps, then the gap is filled, but the assembly time increases
Solution Approach 1:
The invention merges the gap measurement, material removal, and gap filling functions into a single integrated processing operation. The processing device performs all necessary operations in one step, eliminating the sequential steps of measurement, separate manufacturing, and insertion, thereby reducing assembly time while maintaining precision.
Solution Approach 2:
The processing device performs preliminary removal of excess thickness portions before final assembly, preparing the components in advance for precise fitting. This preliminary action eliminates the need for subsequent adjustment operations during assembly, reducing overall assembly time.

AI summary
An assembling device includes a holding member and a processing device. The holding member is configured to hold a first assembly component and a second assembly component. The processing device is configured to process a first excess thickness portion and a second excess thickness portion. The first excess thickness portion is provided at the first assembly component and is configured to adjust a gap between the first assembly component and the second assembly component. The second excess thickness portion is provided at the second assembly component and is configured to adjust the gap.
