Optical Mold Defect Marker Display Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mold inspection techniques fail to clearly indicate the location of defects within molds, making it difficult for operators to quickly identify where failures have occurred.
Innovation Solution
A display control device that optically displays a marker indicating mold defects on the mold itself, using a projector or laser beam, allowing operators to easily locate defects by visually inspecting the mold.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If mold inspection is performed using conventional image display methods, then defect detection capability is provided, but the operator cannot easily grasp the location of defects when the detected defect is small
Solution Approach 1:
The patent introduces a marker as an intermediary element that is optically displayed on the mold at the detected defect location. This marker serves as a mediator between the inspection system and the operator, making the defect location immediately visible and easy to identify without requiring the operator to analyze small defect images
Solution Approach 2:
The patent uses optical display of markers (which may involve color or light intensity changes) to indicate defect locations on the mold. This visual enhancement allows operators to quickly identify defect positions through color or brightness contrasts, resolving the issue of small defects being difficult to locate in conventional grayscale images
2Loss of information
If detailed defect images are displayed, then defect information is provided, but the operator cannot quickly identify the defect location
Solution Approach 1:
The patent separates the defect information display into two components: the detailed defect image (for information completeness) and the optically displayed marker (for quick location identification). The marker is projected directly onto the mold at the defect location, allowing operators to immediately identify where the defect is while maintaining access to detailed images when needed
Solution Approach 2:
The patent adds a spatial dimension to defect information display by projecting markers directly onto the three-dimensional mold surface at the exact defect location. This transforms the two-dimensional image analysis problem into a three-dimensional visual indication system, allowing operators to locate defects instantly by looking at the mold rather than searching through images
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables operators to quickly and accurately identify defect locations without needing to separately check inspection results, improving efficiency and reducing the risk of defective castings.
Implementation Method 1
a display process in which a marker indicating a defect of a mold determined by an inspection result is optically displayed on the mold
Implementation Method 2
In the display process, the controller may control a laser light source to illuminate a laser beam on the mold so that a marker is displayed on the mold
Data Source
AI summary
Provided is the technique that allows an operator or the like to easily grasp in which part of a mold a defect has been detected. A display control device is configured to carry out a display process in which a marker indicating a defect of a mold determined by an inspection result, which is obtained by an inspection of molds, is optically displayed on the mold.
