1Volume of moving object
If traditional filter arrangements are used, then simplicity of structure is maintained, but packaging effectiveness and space utilization are poor
Solution Approach 1:
The filter system is divided into multiple filter elements (first, second, third, and fourth filter elements) arranged in a specific configuration. Each filter element handles a portion of the fluid flow, allowing for better space utilization while maintaining manageable complexity through modular design. The segmented arrangement enables parallel and series flow paths that optimize packaging effectiveness.
Solution Approach 2:
The filter elements are arranged in a nested-like configuration where the first and second filter elements are positioned at a first level, and the third and fourth filter elements are positioned at a second level. This multi-level nesting approach maximizes space utilization by vertically stacking filter elements while maintaining accessible flow paths through the housing.
2Productivity
If filter elements are increased to improve filtration capacity, then filtration efficiency improves, but pressure drop increases
Solution Approach 1:
The fluid flow is segmented into multiple parallel paths through the first, second, third, and fourth filter elements. By distributing the total flow across multiple elements rather than forcing all fluid through a single element, the pressure drop across each individual element is reduced while maintaining high overall filtration capacity. The segmentation creates balanced flow distribution.
Solution Approach 2:
Multiple filter elements are combined in a configuration where their flow paths merge and interact. The first and second filter elements combine their filtered outputs, and the third and fourth filter elements combine their outputs, creating a merged flow that maintains high filtration capacity. This merging approach allows parallel processing of fluid while achieving comprehensive filtration.

This configuration improves filtration efficiency by optimizing fluid flow paths and reducing pressure drop, while allowing for flexible layout designs that maximize space utilization in fluid filtration systems.
Implementation Method 1
Each of the filter elements filters fluid by passing the fluid axially therethrough, namely by passing the fluid through alternately sealed upstream ends of axially extending flow channels, then laterally through a filter media wall segment
