Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information processing devices struggle to synchronize and output audiovisual information, such as video and sound, with numerical data from machine tools, making it difficult for operators to easily identify the cause of abnormalities during machining processes.
Innovation Solution
An information processing device that includes a numerical data storage unit for storing machine tool data, an audiovisual information storage unit for storing video and audio data, and an output control unit that synchronizes and displays numerical data with audiovisual information, using a reference signal to align the timing of both, allowing for simultaneous output and easier identification of abnormality causes.

Engineering Contradiction Analysis
1Device complexity
If a common video camera is used to capture machining process, then the device complexity is reduced, but the synchronization precision between video data and numerical data deteriorates
Solution Approach 1:
The patent introduces a reference signal as an intermediary element that both the video camera and numerical control device can synchronize to. The reference signal generation unit creates a common time reference that mediates between the video capture system and the numerical data system, enabling precise synchronization without requiring complex integration between the two systems.
Solution Approach 2:
The patent replaces complex mechanical or software-based synchronization mechanisms with a simple electrical signal-based reference system. By using a reference signal that can be electronically distributed to both systems, the patent achieves synchronization with minimal device complexity while maintaining high precision.
2Device complexity
If audiovisual information and numerical data are stored separately, then the device complexity is reduced, but the ease of operation for abnormality analysis deteriorates
Solution Approach 1:
The patent merges the separate storage of audiovisual information and numerical data into a unified structured format. By combining these data types with associated metadata (timestamps, reference signal values) into an integrated data structure, the system maintains operational simplicity while enabling easy correlation and analysis of both data types during abnormality investigation.
3Manufacturing precision
If image data is generated at every predetermined sampling time, then the manufacturing precision of operation records is improved, but the productivity is reduced
Solution Approach 1:
The patent performs preliminary actions by generating and storing reference signals and metadata in advance during the machining process. This allows the system to quickly assemble operation records when needed without having to generate all image data at every sampling interval, thus maintaining record precision while improving processing efficiency through selective data assembly.
