Solution Overview

Problem

Existing methods for judging whether a component will incline and rise during laser processing have low accuracy, particularly when using a rotation axis aligned with multiple supports in a straight line.

Innovation Solution

An information processing device is provided with a support extraction unit that identifies the outermost supports for an object corresponding to a cutout region and a judgment unit that determines if the object will rise based on the number of supports at these outermost positions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a plurality of supports aligned in a straight line are set as the rotation axis for rising judgment, then the judgment can be made based on this setting, but the accuracy of the rising judgment becomes low

Engineering Contradiction:
Improveease of judgmentVSAvoidaccuracy of rising judgment
Core Design Contradiction:
Ease of operationVSMeasurement precision

Solution Approach 1:

The patent divides the supports into two categories: supports aligned in a straight line (first supports) and supports not aligned in a straight line (second supports). The judgment unit performs rising judgment separately for each category, applying different judgment logic to each segment. This segmentation allows the system to maintain ease of operation for aligned supports while improving accuracy by identifying cases where non-aligned supports indicate potential rising issues.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent applies different judgment criteria to different locations or configurations of supports. Specifically, when supports are aligned in a straight line, a simpler judgment method is used, whereas when supports are not aligned in a straight line, a more stringent judgment criterion is applied. This local differentiation of judgment quality improves overall accuracy while maintaining operational simplicity for standard cases.

Inventive Principle:
Principle #3Local quality

2Reliability

If all supports are considered for rising judgment, then comprehensive judgment can be made, but the processing load increases

Engineering Contradiction:
Improvecomprehensiveness of judgmentVSAvoidprocessing load
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts and identifies only the outermost supports (supports at the outer edge of the cutout region) as the critical supports for rising judgment. By taking out these specific supports from the complete set of all supports, the system reduces the number of supports that need to be processed while still maintaining comprehensive judgment reliability, as the outermost supports are the most critical for detecting component rising.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

Instead of performing exhaustive analysis on all supports, the patent applies partial action by focusing judgment only on the outermost supports. This selective approach performs sufficient analysis on the critical subset of supports that matter most for rising detection, thereby reducing processing load while maintaining adequate judgment reliability.

Inventive Principle:
Principle #16Partial or excessive action

AI summary

An information processing device includes a support extraction unit that extracts a support supporting an object corresponding to a cutout region at an outermost position among one or more supports supporting the object based on cutout region information indicating the cutout region as a region to be cut out by a laser processing machine and support information indicating the one or more supports supporting the object corresponding to the cutout region and a judgment unit that judges whether the object will incline and rise by being supported by the one or more supports or not based on a support count as the number of supports supporting the object at outermost positions.
