Solution Overview

Problem

Existing molding machine management systems struggle to effectively manage production across multiple machines, as they cannot distinguish between abnormalities occurring in one machine versus multiple machines, making it difficult to take appropriate actions.

Innovation Solution

A molding machine management system that displays production performance and planned status on a time axis for each machine, along with icons representing abnormalities, allowing operators to easily identify the affected machine and time of occurrence, and differentiate severity and progress status of abnormalities.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the system displays abnormality information for multiple molding machines together, then the overall production management is improved, but the ability to distinguish and manage each individual machine's abnormalities deteriorates

Engineering Contradiction:
Improveoverall production management efficiencyVSAvoidindividual machine abnormality distinction
Core Design Contradiction:
ProductivityVSLoss of information

Solution Approach 1:

The system segments abnormality information by dividing it into individual machine-level data units. Each molding machine's abnormalities are separately identified and displayed with unique identifiers, allowing operators to distinguish between different machines while maintaining overall production management. This segmentation enables both aggregate viewing and individual machine analysis simultaneously.

Inventive Principle:
Principle #1Segmentation

2Device complexity

If the system displays only abnormality occurrence time and duration, then the information processing is simplified, but the ability to identify specific affected machines and take targeted actions deteriorates

Engineering Contradiction:
Improveinformation processing complexityVSAvoidtargeted abnormality response
Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

The system applies local quality by providing different levels of information detail in different display contexts. In the overall production management view, abnormality information is displayed concisely with time and duration. When operators select or focus on a specific machine, the system provides detailed abnormality information for that particular machine, enabling targeted responses without overwhelming the overall interface.

Inventive Principle:
Principle #3Local quality

AI summary

Provided is a molding machine management system that manages production of a plurality of molding machines, including: a display unit configured to display a production performance and a planned production status in association with a time axis for each molding machine, and, when the molding machine management system receives an abnormality of a molding machine, to display the abnormality of the molding machine in association with the time axis for each molding machine. The molding machine management system configured as described above can appropriately manage each molding machine.
