Augmented Joint Inspection for Reliable Vehicle Assembly Checks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for inspecting manufactured components do not effectively address the need for a simple, fast, and reliable inspection of joints formed by two components in motor vehicle assemblies, particularly those with complex connections like welding or bonding.
Innovation Solution
A method involving an inspection device that captures and displays a real image of the joint on a display device, allowing for comparison with target joint information, including geometric, temperature, and tolerance data, using augmented reality and computer-based measurements to assess the quality of the joint.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional inspection methods are used for manufactured components, then component manufacturing can be inspected, but joint inspection of assembled components cannot be effectively performed
Solution Approach 1:
The patent uses image capture devices to create visual copies of the joint area, allowing inspection of the actual joint through captured images rather than direct physical measurement. This enables inspection of assembled joints by reproducing their visual appearance on display devices, making the inspection method adaptable to finished assemblies while maintaining reliable detection capabilities.
2Reliability
If detailed joint information is displayed during inspection, then assessment reliability improves, but inspector attention may be diverted from the joint
Solution Approach 1:
The patent merges the captured joint image with target joint information (such as tolerance zones, weld seam paths, or inspection criteria) into a single composite display. This allows the inspector to view both the actual joint appearance and the reference criteria simultaneously in one view, maintaining assessment reliability while eliminating the need to switch between multiple displays or documents, thus preserving ease of operation.
3Productivity
If manual inspection methods are used, then flexibility is maintained, but inspection speed and consistency deteriorate
Solution Approach 1:
The patent implements automated feedback mechanisms where captured joint images are automatically compared against target joint information using image processing algorithms. The system provides immediate visual feedback by highlighting deviations, such as displaying actual weld seam positions against target positions or showing tolerance zone violations. This automated feedback ensures consistent measurement precision across all inspections while dramatically increasing inspection speed through rapid image capture and processing.

AI summary
A method for inspecting a joint of an assembly, in particular an assembly of a motor vehicle, consisting of two components joined together by a joining process, includes the method steps of: orienting an inspection device with respect to at least one region of the joint to be tested, imaging an actual image of the joint to be tested on a display device; and displaying joint information relating to the joint to be tested of the assembly via the display device.
