Augmented Reality Real-Time Quality Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional quality control methods in manufacturing are inefficient, often missing defects until the end of the process, leading to wasted time and materials, especially in complex and high-tolerance manufacturing processes like 3D printing or composite material applications.
Innovation Solution
Implementing real-time quality control using augmented reality by projecting a 3D virtual shape/model onto a work-in-progress part, calibrating a virtual world to the real world, and projecting information onto the physical product to detect defects mid-manufacturing, allowing for immediate corrections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional quality control methods are used, then inspection can be performed, but defects are detected only after complete manufacturing, resulting in wasted time and materials
Solution Approach 1:
The system performs preliminary quality control actions by projecting the virtual model onto the work-in-progress part during manufacturing, enabling defect detection before the manufacturing process is complete. This preliminary inspection allows for immediate correction rather than waiting until the end of manufacturing.
Solution Approach 2:
The system provides real-time feedback by comparing the physical work-in-progress part with the virtual model and displaying deviations through the augmented reality interface. This continuous feedback loop enables operators to make immediate adjustments during the manufacturing process.

3Loss of time
If augmented reality quality control is implemented, then real-time defect detection is enabled, but system complexity increases
Solution Approach 1:
The system uses a universal augmented reality interface that can display multiple types of information (virtual model, deviations, measurements) through a single wearable device. This multi-functional approach consolidates what would otherwise require multiple separate inspection tools and interfaces.
Solution Approach 2:
The augmented reality wearable device acts as an intermediary between the complex quality control system and the operator. It processes and presents information in an intuitive visual format, shielding the operator from system complexity while delivering real-time defect detection capabilities.

AI summary
Various techniques are described herein that provide for real-time quality control during manufacturing using augmented reality. In particular, in one embodiment, techniques herein project a three-dimensional (3D) virtual shape/model onto a work-in-progress part in the real-world in order to see defects in real-time, thus allowing for mid-manufacturing corrections. The embodiments herein generally consist of first calibrating a “virtual world” to the real world, then calibrating the physical product to the virtual world, and lastly projecting information onto the physical product, such as various design information and/or quality control information.
