Press Machine State Display Using Color Bands for Failure Prediction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing failure prediction systems for industrial machines, such as press machines, rely solely on numerical evaluation values from AI, making it difficult for operators to determine the urgency of failures and set appropriate thresholds, hindering easy visual determination of machine abnormalities.
Innovation Solution
A press machine with a display that visually represents the operating state over time using a band-shaped image with color variations, incorporating multiple evaluation values like degree of abnormality, production stability, and manual operation frequency, allowing easy recognition of operational trends and potential failures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If numerical evaluation values from AI are used to indicate operating state, then failure prediction capability is improved, but ease of visual determination by operator deteriorates
Solution Approach 1:
The patent applies color changes to represent different operating states and abnormality levels. The display shows a band-shaped image where color variations indicate the degree of abnormality and time-series changes in operating state, allowing operators to visually determine machine health without interpreting numerical AI evaluation values.
Solution Approach 2:
The patent transforms one-dimensional numerical evaluation values into a two-dimensional band-shaped visual display with time-series information. The band shape extends in the time direction, adding a temporal dimension to the data representation, making it easier for operators to understand operating state trends over time.
2Loss of information
If multiple evaluation values are displayed numerically, then information completeness is improved, but ease of understanding by operator deteriorates
Solution Approach 1:
Multiple evaluation values are encoded into color variations within the band-shaped display. Different colors represent different abnormality levels and types, allowing multiple pieces of information to be conveyed simultaneously through visual color cues rather than requiring operators to read and interpret multiple numerical values.
Solution Approach 2:
The patent merges multiple evaluation values (degree of abnormality, production stability, manual operation frequency) into a unified band-shaped visual representation. This consolidation integrates multiple data streams into a single coherent display that maintains information completeness while improving ease of understanding.
Data Source
AI summary
A press machine is a press machine configured to press a workpiece. The press machine includes a display that displays a state display image which extends in a band shape and indicates an operating state of the press machine during a predetermined period of time up to date. The display displays time series variation in the operating state during the predetermined period of time by variation in a color of the state display image in the band shape in an extending direction.
