Solution Overview
Problem
Aerosol devices used in tool lubrication systems, such as minimum quantity lubrication systems, face challenges in achieving an optimized droplet size distribution and efficient aerosol composition, which affects the performance and efficiency of lubrication processes.
Innovation Solution
The aerosol device incorporates a centrifugal separator and a supply device to generate an aerosol with a specific droplet size distribution by separating larger droplets from the aerosol stream and introducing larger liquid drops, allowing for adjustable droplet size distribution and volumetric flow through the use of multiple carrier ducts and a control device, ensuring optimal aerosol composition at the delivery location.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a separating device is added to separate liquid droplets from the aerosol, then the droplet size distribution is optimized, but the device complexity increases
Solution Approach 1:
The aerosol chamber is divided into distinct functional zones: an annular flow region for aerosol generation and a central region for separated aerosol collection. This spatial segmentation allows different droplet size ranges to be produced and collected separately, optimizing the overall droplet size distribution without requiring complex external separation systems.
Solution Approach 2:
The patent introduces a vertical dimension to the aerosol generation process by creating an annular flow region surrounding a central region. This three-dimensional arrangement enables simultaneous generation of aerosols with different characteristics in different spatial zones, achieving optimized droplet size distribution through spatial differentiation rather than sequential processing.
2Adaptability or versatility
If multiple carrier ducts of different dimensions are provided, then the adaptability for different droplet size distributions is improved, but the device complexity increases
Solution Approach 1:
Multiple carrier ducts are provided, each capable of conveying aerosols with different droplet size distributions to different providing locations. This multi-functional design allows a single device to serve multiple lubrication requirements simultaneously, enhancing adaptability while maintaining a relatively simple overall structure through standardized duct connections.
