Solution Overview

Problem

Visual inspections in automobile manufacturing often result in misjudgments, leading to products being incorrectly qualified or disqualified, which can cause inaccuracies in inspection processes.

Innovation Solution

A display system that uses an augmented reality (AR) display device capable of superimposing qualified and disqualified images onto the real-world inspection space, allowing inspectors to make more accurate judgments by comparing actual products with reference images.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If visual inspection is performed by an inspector, then the inspection process can be completed, but misjudgment occurs leading to reduced inspection accuracy

Engineering Contradiction:

Improveinspection accuracyVSAvoidjudgment reliability

Core Design Contradiction:

Measurement precisionVSReliability

Solution Approach 1:

The patent uses AR technology to display copied images of qualified and disqualified products directly in the inspector's field of view. These reference images serve as visual copies that the inspector can compare against the actual product being inspected, eliminating reliance on subjective judgment and improving inspection accuracy.

Inventive Principle:

Principle #26Copying

Solution Approach 2:

The AR display device acts as an intermediary between the inspection criteria and the inspector. Instead of the inspector directly interpreting complex criteria, the system mediates by presenting visual references of qualified and disqualified products, making the comparison objective and accurate.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If inspection criteria are updated manually, then new standards can be implemented, but time is lost and language translation barriers exist

Engineering Contradiction:

Improvecriteria update flexibilityVSAvoidupdate time

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent replaces manual mechanical processes (printing, translating, distributing physical criteria documents) with an automated digital system. Inspection criteria are stored electronically and can be updated remotely, allowing rapid adaptation to new standards without physical intervention or language translation barriers.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system uses universal visual images that transcend language barriers. The AR display can present reference images and criteria in a universally understandable format, allowing the same system to serve multiple languages and regions without requiring separate translation processes.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A display system which has: a display device configured to be able to display an image superimposed on a reality space; and a managing device configured to manage the image the display device displays, wherein the display device has a display processor configured to read at least one of a qualified image and a disqualified image for an inspection target existing in the reality space from a memory and to display the read image superimposed on the reality space seen through an optical see-through displayer, on the displayer.
