Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing separators with single-use components face issues during transportation due to the rotor being free-floating and undefined in the housing, leading to potential damage to the drum and its internals without additional transport securing means.

Innovation Solution

A magnetic transport securing means, such as ferromagnetic elements, are attached to the outside of the housing to immobilize the rotor during transport, ensuring it is fixed in a defined position using circular ring sector-shaped elements that interact with rotor magnets.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If magnetic bearings are used to hold the rotor in suspension during operation, then the separator insert can be easily replaced and mechanical components are eliminated, but the rotor becomes free-floating and undefined during transportation without additional securing means

Engineering Contradiction:

Improveease of replacementVSAvoidrotor stability during transport

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent replaces mechanical bearing structures with magnetic bearing systems that use magnetic fields to suspend the rotor. During operation, the rotor is held in suspension by magnetic bearings of the frame. During transportation, magnetic transport securing means are used to immobilize the rotor, eliminating the need for complex mechanical transport securing structures while maintaining rotor stability.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces magnetic transport securing means as an intermediary element between the rotor and the housing during transportation. These securing means interact with the rotor magnets to provide stabilization without permanent mechanical contact, allowing the rotor to be securely held during transport while maintaining ease of replacement during operation.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If mechanical transport securing means such as internal tongues or grooves are used, then rotor stability during transport is improved, but the design complexity increases and the inner drum must be rotated for assembly

Engineering Contradiction:

Improverotor stability during transportVSAvoidassembly complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces complex mechanical transport securing means (such as internal tongues, grooves, or clamping rings that require rotation or lifting) with magnetic transport securing means. These magnetic elements are attached to the outside of the housing and interact with rotor magnets to provide stabilization, eliminating the need for complex mechanical assembly operations while maintaining rotor stability during transport.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Reliability

If external clamping rings are used to secure the rotor, then transport stability is improved, but the housing-forming components deform and assembly becomes difficult

Engineering Contradiction:

Improvetransport stabilityVSAvoidassembly ease

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The patent replaces external clamping rings that exert mechanical pressure on housing-forming components with magnetic transport securing means. These magnetic elements interact with rotor magnets to provide transport stability without deforming housing components or requiring difficult assembly operations, as they can be simply attached to the outside of the housing.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

An exchangeable separator insert is designed for insertion into stator magnets of the frame of the separator and includes a housing, which is stationary during operation and which is designed in the manner of a container that is closed except for one or more openings. A rotor is disposed within the housing and is rotatable about an axis of rotation, the rotor having a drum which has one or more openings. At least two rotor magnets are at two axially spaced points of the rotor to keep floating and rotatably support the drum within the housing during operation. For transport or installation, the separator insert is provided with one or more transport securing elements, which operate according to a magnetic principle of action, so that the drum, which freely floats during operation of the separator, is immovable or substantially immovable in the housing during transport or installation.
