Solution Overview

Problem

Existing methods for checking design errors or bugs in production devices are inefficient, as they require processing all combinations of trajectory models, leading to increased information processing and operational inefficiency during virtual device operation checks.

Innovation Solution

An information processing device and method that selectively extracts and displays apparatuses for virtual movement based on their movement ranges, allowing for efficient checking of device operations by identifying potential interference areas and simulating movements in a virtual space.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If all combinations of trajectory models are checked for interference, then the completeness of interference detection is improved, but the amount of information processing increases significantly

Engineering Contradiction:

Improvecompleteness of interference detectionVSAvoidamount of information processing

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts and displays only the apparatus that is to be virtually moved on the display portion, separating it from other apparatuses. This extraction principle reduces the information processing burden by focusing only on the relevant moving apparatus while maintaining complete interference detection through background checking of all apparatus combinations.

Inventive Principle:

Principle #2Taking out (Extraction)

2Measurement precision

If all combinations of trajectory models are checked for interference, then the accuracy of interference detection is improved, but the operational efficiency decreases

Engineering Contradiction:

Improveaccuracy of interference detectionVSAvoidoperational efficiency

Core Design Contradiction:

Measurement precisionVSProductivity

Solution Approach 1:

The patent segments the interference checking process into two parts: (1) comprehensive background checking of all apparatus combinations for accurate interference detection, and (2) selective display and virtual movement of only the specific apparatus to be checked. This segmentation maintains detection accuracy while improving operational efficiency by reducing the scope of virtual movement simulations.

Inventive Principle:

Principle #1Segmentation

3Device complexity

If the number of apparatuses to be checked is reduced, then the information processing is decreased, but the ability to detect all potential interferences is worsened

Engineering Contradiction:

Improveinformation processingVSAvoidability to detect all potential interferences

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The patent uses the display portion as an intermediary that selectively presents only the apparatus to be virtually moved, while the control portion continues to perform comprehensive interference checking of all apparatus combinations in the background. This intermediary approach allows reduced visual complexity while maintaining complete interference detection capability.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

An information processing device is configured to virtually execute motion of a device including a plurality of apparatuses. The information processing device includes a display portion and a control portion. The control portion is configured to extract an apparatus to be virtually moved, from the apparatuses on a basis of movement ranges of the apparatuses and display the apparatus on the display portion, as a check object.
