Oil Mist Concentration Management for Machine Tool Ventilation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In metal machining factories, oil mist concentration varies significantly across different areas due to varying coolant usage and ventilation performance, leading to potential operation failures and inefficient working environments.
Innovation Solution
An oil mist concentration management apparatus that acquires state quantities and oil mist concentrations from multiple areas, identifies abnormal areas based on these measurements, and notifies users to improve ventilation performance and working conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple machine tools perform various types of machining with varying coolant usage, then productivity and machining flexibility are improved, but oil mist concentration becomes uneven across different areas leading to poor working environment
Solution Approach 1:
The patent divides the factory space into multiple measurement areas and monitors oil mist concentration in each area separately. By segmenting the monitoring system to match the segmented machining areas, the system can identify which specific areas have high oil mist concentrations and target ventilation improvements accordingly, rather than treating the entire factory as a single zone.
Solution Approach 2:
The patent implements area-specific oil mist concentration monitoring and ventilation control. Each measurement area has its own concentration sensors and is associated with specific machine tools, allowing for localized quality assessment and targeted ventilation performance improvement in areas where it is most needed.
2Measurement precision
If oil mist concentration is monitored in the control panel of individual machine tools, then local oil mist management is improved, but overall factory-wide oil mist distribution and ventilation performance cannot be identified
Solution Approach 1:
The patent combines individual machine tool control panel monitoring with factory-wide centralized monitoring. The oil mist concentration measurement functions are merged into a unified system that collects data from multiple areas simultaneously, enabling both local precision measurement and comprehensive factory-wide distribution analysis through a single integrated platform.
Solution Approach 2:
The patent creates a universal monitoring system that serves multiple functions: it measures oil mist concentration at individual machine tools, tracks factory-wide distribution patterns, identifies ventilation performance issues, and provides comprehensive management capabilities. This multi-functional system eliminates the need for separate local and central monitoring systems.
3Device complexity
If ventilation performance is not optimized in specific areas, then device complexity is reduced, but working environment deteriorates due to high oil mist concentration in low-ventilation areas
Solution Approach 1:
The patent implements preliminary identification of areas with low ventilation performance through continuous monitoring and analysis of oil mist concentration data. By detecting problematic areas in advance through the management apparatus, the system enables proactive ventilation optimization before working conditions deteriorate, allowing for planned rather than reactive system modifications.
Solution Approach 2:
The patent establishes a feedback loop where oil mist concentration measurements from multiple areas are continuously monitored, analyzed, and used to identify ventilation performance issues. The system provides feedback information about which areas have high oil mist concentrations relative to their machine tool activity, enabling targeted ventilation improvements based on actual measured conditions rather than assumptions.

AI summary
An oil mist management system includes a machine tool, an oil mist concentration measuring apparatus for measuring concentration of oil mist, and a flow meter for detecting the flow rate of coolant, in each of a plurality of areas. A data processing apparatus determines whether distribution of the oil mist in the plurality of areas is normal or abnormal on an area-by-area basis, based on the concentration of the oil mist and the flow rate of coolant in each of the plurality of areas, and identifies an abnormal area. Further, the oil mist management system notifies a user of the abnormal area by an output device.
