Composite Grommet Sleeve Layout for Dense Pipe Sealing

Solution Overview

Problem

Existing sleeve designs for sealing line arrangements against jackets require larger jackets to accommodate multiple lines due to the radial space needs of individual grommets, limiting the number of grommets and the diameters they can accommodate.

Innovation Solution

The sleeve features composite grommets that are molded onto each other, allowing for a continuous outer contour merge and increased packing density, enabling more grommets to be arranged or larger diameters to be accommodated without increasing the jacket diameter, with axial spacing and elastic design for flexibility.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If individual cylindrical or conical grommets are used and spaced apart on the sleeve, then each grommet can accommodate lines, but the radial space required limits the number of grommets and their size relative to the sleeve diameter

Engineering Contradiction:

Improvenumber of grommetsVSAvoidsleeve diameter

Core Design Contradiction:

Quantity of substanceVSArea of stationary object

Solution Approach 1:

Multiple grommets are merged into a single composite grommet structure where individual grommet cavities are integrated into one unified component. This eliminates the radial spacing requirements between separate grommets, allowing more grommet cavities to be arranged within the same sleeve diameter.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

Multiple grommet cavities are nested within the composite grommet structure, with each cavity designed to receive a line. The nested arrangement allows efficient use of internal space while maintaining the external contour required for sealing against the jacket.

Inventive Principle:

Principle #7Nested doll (Nesting)

2Quantity of substance

If individual grommets are spaced apart on the sleeve, then each grommet can seal against lines, but the radial space required reduces the number of grommets that can fit on the sleeve

Engineering Contradiction:

Improvenumber of grommetsVSAvoidgrommet arrangement

Core Design Contradiction:

Quantity of substanceVSDevice complexity

Solution Approach 1:

Multiple grommets are merged into a single composite grommet structure where individual grommet cavities are integrated into one unified component. This eliminates the radial spacing requirements between separate grommets, allowing more grommet cavities to be arranged within the same sleeve diameter.

Inventive Principle:

Principle #5Merging (Combining)

3Quantity of substance

If larger jackets are used to accommodate more lines with individual grommets, then more lines can be sealed, but the jacket diameter increases

Engineering Contradiction:

Improvenumber of linesVSAvoidjacket diameter

Core Design Contradiction:

Quantity of substanceVSLength of stationary object

Solution Approach 1:

Multiple grommets are merged into a single composite grommet structure where individual grommet cavities are integrated into one unified component. This eliminates the radial spacing requirements between separate grommets, allowing more grommet cavities to be arranged within the same sleeve diameter.

AI summary

The invention relates to a sleeve (1, 1') for sealing a pipe assembly against a jacket (101) through which the pipe assembly passes, wherein the sleeve (1) has a first sealing section (5) configured for fluid-tight, end-end contact with the jacket (101), and several nozzles (7a, b; 7a, b, c), each of which has a second sealing section (12) configured for fluid-tight contact with a pipe of the pipe assembly. It is proposed that some or all of the nozzles (7a, b; 7a, b, c) are formed as a composite (7), wherein the nozzles (7a, b; 7a, b, c) are integrally formed together in a composite (7).
