Aircraft Inspection Support Device Using 3D Model Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aircraft inspection support devices struggle to associate inspection positions with inspection results when components, such as rivets, are not detailed in the aircraft's design data, especially after shape changes due to repairs or maintenance.
Innovation Solution
An aircraft inspection support device and method that generate a three-dimensional model of the aircraft, acquire inspection positions, and store these positions and results in association with each other using a control unit, even if components were not initially stored in the design data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If inspection position is specified using design data, then inspection results can be associated with design positions, but components not stored in design data (such as rivets or modified components) cannot be properly tracked
Solution Approach 1:
The patent creates a three-dimensional model copy of the aircraft component structure to represent actual inspection targets. This digital twin approach allows the system to track inspection positions even when components have been modified or are not present in original design data, by generating updated three-dimensional models that reflect current component states.
Solution Approach 2:
The patent transitions from two-dimensional design data to three-dimensional spatial coordinates for inspection position specification. By using three-dimensional model positions and coordinates, the system can accurately locate and track inspection targets regardless of whether they exist in original design data, enabling comprehensive tracking of all inspectable components.
2Measurement precision
If detailed component data is stored for all components, then inspection positions can be precisely identified, but the system becomes complex and difficult to maintain
Solution Approach 1:
The patent uses a universal three-dimensional model representation that serves multiple functions: it provides spatial coordinates for inspection positioning, stores component geometric information, and enables tracking of inspection history. This single data structure eliminates the need for separate detailed component databases while maintaining precise identification capabilities.
Solution Approach 2:
The system automatically generates and updates three-dimensional models based on inspection data, eliminating the need for manual data entry and maintenance. The three-dimensional model serves as a self-updating database that automatically reflects current component states, reducing operational complexity while maintaining high measurement precision.
