Image Processing Apparatus Sound-Based Malfunction Diagnosis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Image processing apparatuses often face challenges in diagnosing malfunctions due to inability to repeat abnormal noises, which can only be heard by maintenance personnel, and recording such noises is often restricted for security reasons, leading to increased time in identifying the cause of malfunctions.
Innovation Solution
The image processing apparatus is equipped with a processor that generates screens for users to select malfunctioning parts and corresponding reference sounds, allowing the apparatus to transmit selected sound information to another device, enabling notification of a sound similar to the abnormal noise, even if the actual noise cannot be recorded.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the image processing apparatus transmits sound information to notify malfunctions, then the reliability of malfunction notification is improved, but the device complexity increases due to additional sound selection and transmission components
Solution Approach 1:
The patent creates a copy of the abnormal noise sound and stores it in the sound information storage unit. Instead of transmitting the actual abnormal noise, the system transmits this pre-stored sound copy that reproduces the malfunction sound, thereby improving notification reliability without requiring complex real-time recording and transmission capabilities
Solution Approach 2:
The system performs preliminary action by pre-storing sound information corresponding to various malfunction sounds in the sound information storage unit before malfunctions occur. This allows the system to quickly transmit appropriate sound notifications when malfunctions happen, improving reliability without adding complex real-time processing components
2Ease of operation
If the apparatus allows user selection of sound information, then the ease of operation is improved, but the time required to identify and transmit the correct sound increases
Solution Approach 1:
The system implements feedback by playing back the selected sound information through the sound output unit, allowing the operator to verify whether the transmitted sound matches the actual abnormal noise. This feedback mechanism ensures accurate malfunction identification while maintaining ease of operation through intuitive sound comparison
Solution Approach 2:
The patent stores multiple sound information samples corresponding to the same type of malfunction in the sound information storage unit. The operator can select from multiple similar sounds to find the best match, which may take slightly longer but significantly improves ease of operation by providing more selection options for accurate identification

AI summary
An image processing apparatus includes a display device and a processor. The processor is configured to generate a first screen for display on the display device and on which one of a plurality of malfunctioning part candidates of the image processing apparatus and one of a plurality of timings at which a particular sound was output by the image processing apparatus that malfunctioned, are selectable, when a first malfunctioning part candidate and a first timing are selected on the first screen, generate a second screen for display on the display device and on which one or more reference sounds corresponding to the particular sound are selectable, and when one of the reference sounds is selected on the second screen, generate error information indicating the first malfunctioning part candidate and the selected reference sound.
