Filter Element Drain Channels for Moisture Damage Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing filter devices face issues with inefficient liquid drainage, leading to moisture damage and reduced lifespan due to uncontrolled leakage and insufficient draining capabilities.
Innovation Solution
The filter element and device incorporate a frame with integrated drain channels or grooves for efficient liquid drainage, and a central main structure with interconnected side parts forming drain tubes to facilitate controlled liquid outflow, eliminating the need for additional components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If filter elements are used to clean gaseous fluids containing liquid particles, then filtering performance is improved, but liquid accumulation causes moisture damage and reduces device lifespan
Solution Approach 1:
The patent extracts the liquid drainage function from the filter element structure by integrating drain channels directly into the frame. This allows liquid to be separated and removed from the filtering system, preventing moisture accumulation and damage while maintaining continuous filtering operation.
Solution Approach 2:
The drain channels act as an intermediary structure between the filter medium and the external environment. They provide a controlled pathway for liquid to exit the filter element, mediating between the filtering process that produces liquid and the need to prevent moisture damage.
2Device complexity
If traditional filter devices without integrated drainage are used, then device structure is simpler, but liquid leakage is uncontrolled and maintenance frequency increases
Solution Approach 1:
The patent merges the drainage function with the existing frame structure of the filter element. By integrating drain channels into the frame rather than adding separate drainage components, the device structure remains simple while achieving controlled liquid drainage and reduced maintenance needs.
3Productivity
If filter medium surface area is increased to improve filter performance, then filtering efficiency is enhanced, but liquid accumulation and drainage requirements increase
Solution Approach 1:
The patent segments the frame structure into multiple parts, each containing drain channels. This segmentation allows liquid to be drained from different regions of the filter element simultaneously, effectively handling the increased liquid accumulation that results from larger filter medium surface area.

Implementation Method 1
a filter medium for cleaning a fluid stream guided through the filter medium, whereby a liquid is separated from the fluid stream
Implementation Method 2
the at least one drain channel provided in the frame, which is usually located on a lower frame part, ensures that liquid collected in the filter element drains off
