Augmented Printed Board Inspection via Design Data Superimposition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The miniaturization of electronic parts on printed boards makes it difficult for operators to track wires and components, as conventional circuit symbols are often not printed, leading to increased workload and identification challenges during development and evaluation.
Innovation Solution
An information processing system that captures images of the printed board, extracts design information, and superimposes relevant data onto the image, allowing for enhanced visualization and identification of components and wires through a terminal device and information processing device communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If electronic parts are miniaturized and mounted densely, then the functionality and integration of the printed board are improved, but the difficulty of tracking wires and components increases
Solution Approach 1:
The patent introduces an intermediary system consisting of image capture devices, processing units, and display devices that mediate between the operator and the densely mounted electronic parts. This intermediary system captures images of the printed board, processes them to identify components and wires, and displays enhanced images that make tracking easier without changing the physical density of the circuit board.
2Device complexity
If conventional inspection methods are used, then the process is simple, but the ability to identify individual wires and components is insufficient
Solution Approach 1:
The patent creates a visual copy or representation of the printed board through image capture and processing. Instead of directly manipulating the physical board, the system creates a digital copy that can be enhanced, processed, and displayed to identify individual wires and components with higher accuracy while maintaining operational simplicity.
Solution Approach 2:
The patent transitions from two-dimensional visual inspection to a multi-dimensional approach by capturing images, processing them through computational algorithms, and displaying enhanced versions. This adds temporal and computational dimensions to the inspection process, enabling precise identification of individual components and wires without complicating the physical inspection process.
3Device complexity
If design information is not superimposed on captured images, then the system remains simple, but the operator's workload increases
Solution Approach 1:
The patent merges multiple functions into a single integrated system: image capture, design information retrieval, image processing, and display. By combining these functions, the system provides comprehensive assistance to reduce operator workload while maintaining relative simplicity through integration rather than separate complex subsystems.

AI summary
An information processing system includes a terminal device and an information processing device. The terminal device captures an image of at least a portion of a printed board and transmits the captured image of the at least a portion of the printed board to the information processing device. Based on the captured image and design information items about a plurality of elements included in the printed board, the information processing device extracts design information items about one or more elements constituting the at least a portion of the printed board, and generates an image in which images based on the design information items about the one or more elements are superimposed on the captured image. The information processing device transmits the generated image to the terminal device. The terminal device displays the generated image, received from the information processing device, on a display of the terminal device.
