Solution Overview

Problem

Existing systems fail to clearly indicate the position of paint defects on actual objects, making defect identification and repair inefficient.

Innovation Solution

An output apparatus that determines the center point of a defect and outputs image data to this point or adjacent areas, using sensors and control units to enhance defect visibility and repair efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If the system displays the paint defect on an image indicating the surface of the object, then the defect information is provided, but the position of the defect is not clear in the actual object

Engineering Contradiction:
Improvedefect position informationVSAvoiddefect identification ease
Core Design Contradiction:
Loss of informationVSEase of operation

Solution Approach 1:

The patent projects an image copy of the defect directly onto the actual object surface, creating a visual replica that shows the exact position, shape, and appearance of the defect. This allows operators to see the defect both in the captured image and projected on the object, eliminating position ambiguity and making defect identification immediate and accurate.

Inventive Principle:
Principle #26Copying

2Productivity

If the system stops displaying the paint defect when measures have been taken, then the display is updated, but the position clarity is not improved

Engineering Contradiction:
Improverepair process efficiencyVSAvoiddefect position precision
Core Design Contradiction:
ProductivityVSMeasurement precision

Solution Approach 1:

By projecting the defect image directly onto the object surface, the system maintains precise position information throughout the repair process. The projected image serves as a persistent visual reference that remains aligned with the actual defect location, allowing operators to verify their work against the projected overlay without losing position accuracy.

Inventive Principle:
Principle #26Copying

AI summary

An output apparatus (1) includes a control unit (17) to acquire a defect on an object from an inspection device, determine a center point (C) of the defect on the object (2), and output image data to the center point of the defect on the object or to a portion adjacent to the center point (C) of the defect on the object.
