Filter cartridge comprising a plurality of filter elements
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The filtration performance of existing filter cartridges is limited by their effective filter surface, requiring multiple cartridges in parallel to increase surface area, which complicates individual insertion and replacement, leading to increased user effort and contact with contaminated components.
Innovation Solution
A filter cartridge design featuring a plurality of tube-shaped filter elements between a bottom and a cover with corresponding openings, allowing for increased filtration surface area without altering structural space or efficiency, with options for cylindrical, conical, or pleated filter elements arranged symmetrically to optimize space utilization and facilitate easy exchange.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If multiple filter cartridges are arranged in parallel to increase filter surface area, then filtration performance is improved, but device complexity and ease of operation deteriorate due to individual insertion and replacement requirements
Solution Approach 1:
Multiple filter elements that were previously separate cartridges are merged into a single integrated filter cartridge. The filter elements are arranged side-by-side within one housing structure, allowing them to function as a unified replaceable unit while maintaining their individual filtration surfaces.
Solution Approach 2:
The filter cartridge is segmented into multiple filter elements arranged in parallel within the same housing. Each filter element maintains its own filtration surface while being structurally integrated into a single replaceable cartridge, enabling increased surface area without increasing assembly complexity.
2Area of moving object
If multiple filter cartridges are arranged in parallel to increase filter surface area, then filtration performance is improved, but ease of operation worsens due to increased user effort for individual replacement
Solution Approach 1:
Multiple filter elements are combined into a single replaceable cartridge unit. Users replace one integrated cartridge instead of multiple separate cartridges, significantly reducing the physical effort and time required for maintenance while maintaining the total filtration surface area.
3Area of moving object
If multiple filter cartridges are arranged in parallel to increase filter surface area, then filtration performance is improved, but ease of operation worsens due to increased contact with contaminated components
Solution Approach 1:
Multiple filter elements are integrated into a single cartridge with a common housing and sealing structure. Users handle and replace one unified component rather than multiple separate contaminated cartridges, minimizing exposure to contaminated surfaces and improving operational safety.
