Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing Halbach arrays of electromagnets fail to achieve significant magnetic field enhancement on one side and proportional reduction on the opposite side due to lack of physical contiguity between adjacent cores, resulting in impaired interactions and a severely disabled or negated Halbach effect.

Innovation Solution

Configuring horizontal electromagnetic cores with magnetic flux conduits, such as fork-like protrusions, to establish substantial contiguity with vertical cores, allowing direct magnetic flux delivery and forming flux apertures that enhance and cancel magnetic fields, similar to permanent magnet arrays.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Force

If ordinary electromagnets are arranged in Halbach array sequence, then the array structure is formed, but the magnetic field enhancement and reduction effects are severely disabled or non-existent due to lack of physical contiguity between cores

Engineering Contradiction:

Improvemagnetic field enhancementVSAvoidphysical contiguity requirement

Core Design Contradiction:

ForceVSDevice complexity

Solution Approach 1:

Magnetic flux conduits are introduced as intermediary elements between adjacent electromagnetic cores. These conduits physically connect the cores and guide magnetic flux between them, enabling the Halbach array effect in electromagnets. The conduits act as mediators that transfer magnetic flux from one core to adjacent cores, creating the necessary magnetic field enhancement on one side and reduction on the other side of the array.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The invention merges the functions of separate electromagnetic cores by establishing physical contiguity through magnetic flux conduits. Adjacent cores are connected to form an integrated magnetic circuit where flux from multiple cores combines constructively on one side of the array and cancels destructively on the opposite side, achieving the Halbach array effect.

Inventive Principle:

Principle #5Merging (Combining)

2Reliability

If magnetic windings around vertical electromagnetic cores are present, then the electromagnets function as intended, but they act as a dual barrier (physical and energized) that negates the Halbach effect

Engineering Contradiction:

Improveelectromagnet functionVSAvoidHalbach effect

Core Design Contradiction:

ReliabilityVSForce

Solution Approach 1:

Magnetic flux conduits serve as intermediaries that bypass the barrier effect of magnetic windings. The conduits provide a dedicated path for magnetic flux that is not blocked by the windings, allowing flux to pass through and interact with adjacent cores despite the presence of energized windings.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The invention extracts the magnetic flux path from the conventional electromagnet structure by introducing separate magnetic flux conduits. These conduits carry the flux that would otherwise be blocked by the windings, separating the flux transmission function from the winding structure.

Inventive Principle:

Principle #2Taking out (Extraction)

3Force

If physical contiguity between adjacent electromagnetic cores is established, then the Halbach effect is enabled, but the device complexity increases due to additional magnetic flux conduits

Engineering Contradiction:

Improvemagnetic field enhancementVSAvoidmagnetic flux conduit structure

Core Design Contradiction:

ForceVSDevice complexity

Solution Approach 1:

The magnetic flux conduits serve multiple functions: they provide physical contiguity between cores, guide magnetic flux between adjacent cores, and enable the Halbach array effect. This multi-functionality reduces the need for separate components and justifies the added structural elements as necessary for achieving the desired magnetic field enhancement.

Inventive Principle:

Principle #6Universality (Multi-functionality)
