Abstract

A monolithic open cell structure apparatus including an open cell structure housing including a first side, a second side opposite the first side, a first opening located at the first side, and a second opening located opposite the first opening at a second side. The monolithic open cell structure apparatus also including a filtration portion extending from the first side to the second side within the open cell structure housing. The monolithic open cell structure apparatus further including a retaining partition that at least partially encloses the filtration portion within the open cell structure housing. The monolithic open cell structure apparatus is a single piece including a unitary structure.

First claim

What is claimed is:

1. A monolithic open cell structure apparatus, comprising:
an open cell structure housing comprising a first side, a second side opposite the first side, a first opening located at the first side, and a second opening located opposite the first opening at a second side;
a filtration portion extending from the first side to the second side within the open cell structure housing, the filtration portion having an open cell structural geometry that includes a plurality of cells; and
a retaining partition that at least partially encloses the filtration portion within the open cell structure housing, wherein the retaining partition includes a plurality of individual sections, each section having a plurality of pillars configured to fit within a cell of the plurality of cells,
wherein the monolithic open cell structure apparatus is a single piece comprising a unitary structure.

2. The monolithic open cell structure apparatus of claim 1 , wherein the monolithic open cell structure apparatus has no joints or seams.

3. The monolithic open cell structure apparatus of claim 1 , wherein the open cell structural geometry is configured to perform filtration.

4. The monolithic open cell structure apparatus of claim 3 , wherein the open cell structural geometry is a tetradecahedron structure.

5. The monolithic open cell structure apparatus of claim 1 , wherein the open cell structural geometry is a honeycomb open cell structure.

6. The monolithic open cell structure apparatus of claim 1 , wherein the retaining partition is integrated into each of the plurality of cells.

7. The monolithic open cell structure apparatus of claim 5 , wherein the retaining partition is integrated into each of the plurality of cells.

8. The monolithic open cell structure apparatus of claim 7 , wherein each of the plurality of cells comprises a section of the retaining partition configured to fit within the cell.

9. The monolithic open cell structure apparatus of claim 1 , wherein the plurality of pillars extend across the cell and terminate at opposing sides of the cell.

10. The monolithic open cell structure apparatus of claim 1 , wherein each of the plurality of pillars have a circular shape.

11. The monolithic open cell structure apparatus of claim 9 , wherein each of the plurality of pillars have a diamond shape.

12. The monolithic open cell structure apparatus of claim 9 , wherein each of the plurality of pillars have a teardrop shape.

13. The monolithic open cell structure apparatus of claim 9 , wherein each of the plurality of pillars have a square shape.

14. The monolithic open cell structure apparatus of claim 9 , wherein the plurality of pillars are organized in a first row and a second row in a staggered pattern.

15. The monolithic open cell structure apparatus of claim 9 , wherein the plurality of pillars are organized in a first row that is arched in shape.

16. The monolithic open cell structure apparatus of claim 1 , wherein the plurality of pillars are oriented parallel to each other.
