Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The filter screen in the filter device for cutting fluid circulation systems in wire cutting machines becomes blocked easily, leading to reduced flow and poor filtration efficiency, necessitating manual cleaning or replacement, which is inefficient and unreliable, affecting machining quality and efficiency.
Innovation Solution
A filter device with an integrated ultrasonic cleaning assembly that automatically cleans the filter screen, maintaining filtration efficiency without disassembly, combined with a filter circulation system including a spraying, collecting, and heat exchange system to enhance cleaning efficiency and reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual cleaning or replacement of the filter screen is used, then the filter screen can be cleaned, but cleaning efficiency is low and it influences machining efficiency
Solution Approach 1:
The filter screen performs self-cleaning through an integrated ultrasonic cleaning assembly that automatically removes blockages without requiring manual disassembly or intervention, thereby maintaining high cleaning efficiency while avoiding disruption to machining operations
Solution Approach 2:
The patent replaces manual mechanical cleaning with an ultrasonic cleaning system that uses high-frequency vibrations to remove debris from the filter screen, significantly improving cleaning efficiency and eliminating the need for manual disassembly that would interrupt machining
2Reliability
If manual cleaning of the filter screen is performed, then the filter screen can be cleaned, but the effect is uncertain leading to low reliability
Solution Approach 1:
The patent replaces unreliable manual cleaning operations with an automated ultrasonic cleaning system that provides consistent and reliable cleaning results through controlled high-frequency vibrations, eliminating human variability in cleaning effectiveness
Solution Approach 2:
The filter screen automatically cleans itself through the ultrasonic cleaning assembly, ensuring consistent and reliable cleaning performance without depending on manual operations, thereby improving cleaning reliability
3Productivity
If the filter screen is not cleaned regularly, then machining efficiency is maintained, but the filter screen becomes blocked resulting in poorer filter effect and smaller flow amount
Solution Approach 1:
The ultrasonic cleaning assembly operates continuously or periodically to maintain the filter screen in a clean state, ensuring continuous effective filtration without interrupting machining operations, thereby maintaining both productivity and filtration reliability
Solution Approach 2:
The ultrasonic cleaning assembly performs preliminary cleaning actions on the filter screen before significant blockages occur, preventing filtration efficiency degradation while maintaining uninterrupted machining operations
