Solution Overview

Problem

Existing flow elements for separating devices, such as those used to separate oil from gas flows, lack a simple and stable connection mechanism, leading to unreliable stacking and alignment of multiple elements.

Innovation Solution

A flow element with a disc-shaped base body featuring projections and receiving sections on both sides, allowing for a tongue and groove connection that enables secure, torsion-proof stacking and alignment of multiple elements, with channels designed to guide fluid along a curved path for efficient separation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If flow elements are designed without specific connection features, then the construction remains simple, but the stacking and connection stability between multiple flow elements deteriorates

Engineering Contradiction:
Improveconstruction simplicityVSAvoidconnection stability
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The flow element is segmented into modular components with standardized connection features (projections and receiving sections) that enable reliable stacking while maintaining individual element simplicity. Each flow element is an independent unit that can be reliably connected to others through the tongue and groove connection system.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Projections and receiving sections serve as intermediary connection features between flow elements. These features mediate the connection process, providing a simple yet reliable interface that enables stable stacking without complex fastening mechanisms.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of manufacture

If flow elements are designed with basic connection features, then manufacturing remains simple, but the precision of alignment and concentricity between stacked elements deteriorates

Engineering Contradiction:
Improvemanufacturing simplicityVSAvoidalignment precision
Core Design Contradiction:
Ease of manufactureVSManufacturing precision

Solution Approach 1:

The connection features utilize asymmetric tongue and groove geometry where projections on one flow element fit into corresponding receiving sections on the adjacent element. This asymmetric design provides inherent alignment guidance that ensures precise concentricity and rotational alignment during stacking, while the features remain simple to manufacture.

Inventive Principle:
Principle #4Asymmetry

Solution Approach 2:

The projections and receiving sections are designed to self-align during the stacking process. The geometric configuration of these features automatically guides the flow elements into correct alignment and concentric positions without requiring additional alignment tools or complex manufacturing processes.

Inventive Principle:
Principle #25Self-service

3Device complexity

If flow elements lack torsion-proof connection features, then the structure remains simple, but the resistance to rotational displacement between stacked elements deteriorates

Engineering Contradiction:
Improvestructural simplicityVSAvoidtorsion resistance
Core Design Contradiction:
Device complexityVSStrength

Solution Approach 1:

The connection features extend in the radial dimension perpendicular to the central axis of the flow element. Projections and receiving sections are arranged to provide form-fitting connections that resist rotational displacement through their radial geometry, adding torsional strength without increasing axial structural complexity.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The channels and connection features incorporate curved geometries that follow the radial flow path. The projections and receiving sections are shaped to provide smooth, curved interfaces that resist torsional forces while maintaining fluid flow continuity and structural simplicity.

Inventive Principle:
Principle #14Spheroidality (Curvature)

AI summary

To provide a flow element (112) for a separation device, which flow element is of simple construction and can be connected in a stable manner to further structurally identical flow elements, it is proposed that the flow element comprise a disk-shaped main body (146) which comprises a first side (150) and a second side (152) situated opposite the first side, wherein the first side and/or the second side comprises multiple ducts (154) through which, when the flow element is in the installed state in the separation device, a fluid can be conducted outward from a central opening of the main body arranged centrally in the disk-shaped main body or can be conducted from the outside to the centrally arranged central opening, wherein the main body (146) comprises multiple receiving sections (168) at least on the first side and multiple projections (160) at least on the second side, wherein, when the flow element is in the installed state, the projections can be placed in engagement with the receiving sections of a substantially structurally identical further flow element mounted on the flow element.
