Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current manufacturing systems lack comprehensive and intuitive methods for tracking the progress of complex products, such as aircraft, during assembly, making it difficult to quickly identify and resolve assembly issues.
Innovation Solution
The use of three-dimensional (3D) progress information from machine tools to create dynamic 3D scenes that depict the ongoing assembly of products, allowing operators to visualize the assembly status and location of manufacturing errors in real-time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If traditional 2D charts and tables are used to track manufacturing progress, then the system is simple to implement, but assembly issues cannot be identified and resolved quickly
Solution Approach 1:
The patent transitions from traditional 2D charts and tables to a 3D virtual scene that spatially represents the physical assembly environment. This dimensional change allows operators to visually perceive assembly status and identify issues instantly, resolving the contradiction between quick issue identification and system complexity by providing intuitive spatial context that 2D representations cannot convey.
Solution Approach 2:
The system creates a virtual copy of the physical assembly scene using 3D models that mirror the actual product and components. This virtual replica enables operators to monitor assembly progress and detect errors by comparing the virtual scene with the physical reality, achieving rapid issue identification without requiring complex physical monitoring equipment.
2Reliability
If comprehensive tracking of all assembly progress is implemented, then manufacturing quality improves, but the complexity of the monitoring system increases
Solution Approach 1:
By creating a virtual copy of the assembly scene using 3D models, the system comprehensively tracks all assembly progress without requiring complex physical monitoring equipment. The virtual scene serves as a digital twin that captures complete assembly information, improving manufacturing quality while avoiding the complexity of extensive physical sensors and monitoring devices.
Solution Approach 2:
The 3D virtual scene serves multiple functions simultaneously: it displays assembly progress, identifies errors, provides spatial context, and enables quality verification. This multi-functionality achieves comprehensive tracking and improved manufacturing quality through a single integrated system rather than multiple separate complex monitoring systems.
3Difficulty of detecting and measuring
If detailed 3D visualizations are created to show assembly status, then operators can quickly identify errors, but more data processing and computational resources are required
Solution Approach 1:
The patent uses 3D visualization to represent assembly status, making error detection intuitive through spatial representation. This approach improves ease of detecting manufacturing errors by providing visual and spatial context, while the computational requirements are managed by efficiently rendering only the necessary 3D elements based on assembly progress data from machine tools.
Data Source
AI summary
Systems and methods are provided for creating three dimensional (3D) visualizations of in-process products. One embodiment is an apparatus that includes a controller and an interface. The controller is able to generate a 3D scene depicting ongoing assembly of a product by a machine tool. The scene includes a 3D model of the product and a 3D model of the machine tool, and the 3D models are placed within the scene based on a location of the product and a location of the machine tool. The interface is able to receive an update from the machine tool indicating a 3D placement of a part that has been attached by the machine tool to the product. The controller is also able to acquire a 3D model of the part, to insert the 3D model of the part within the scene based on the 3D placement, and to provide the scene for display to a user.
