Solution Overview

Problem

Existing magnet arrangements for magnetic levitation vehicles face issues with mechanical loads affecting sensor reliability and complex fastening requirements, leading to potential failure and reduced fail-safety.

Innovation Solution

The sensor head is integrated into the magnet arrangement as a permanent part, eliminating the need for complex mounting and preventing detachment, with electronic modules separated and protected from mechanical shocks, allowing for increased reliability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If the sensor head is mounted next to the magnetic pole with complex fastening technology to ensure precise positioning, then the sensor can accurately monitor the gap, but the number of components increases and the fail-safety is reduced

Engineering Contradiction:
Improvegap monitoring accuracyVSAvoidfastening technology complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The sensor head is integrated directly into the magnet arrangement as a permanent part, combining the sensor functionality with the magnetic pole structure. This eliminates the need for separate fastening components and complex mounting procedures, while maintaining precise positioning for gap monitoring.

Inventive Principle:
Principle #5Merging (Combining)

2Ease of manufacture

If the sensor head is integrated into the magnet arrangement as a permanent part, then complex mounting measures are eliminated, but the sensor head may be exposed to high mechanical loads during operation

Engineering Contradiction:
Improvemounting simplicityVSAvoidsensor reliability under mechanical load
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The sensor system is divided into two separate parts: the sensor head integrated into the magnet arrangement for structural support and positioning, and the electronic module separated and protected from mechanical loads. This segmentation allows the sensor head to benefit from simple integration while the electronic components are protected from high mechanical stresses during operation.

Inventive Principle:

AI summary

A magnetic polar arrangement which is intended for magnetic levitation vehicles is described, said magnetic polar arrangement having at least one magnetic pole (22) with a core (6) which defines a magnetic pole surface (23), and with a winding (5) which is set back with respect to the magnetic pole surface (23) in order to form a free space (24). The magnetic pole (22) is provided with a sensor which contains a sensor head (9a), which is arranged at least partially in the free space (24), and an electronic module (9b). According to the invention the sensor head (9a) is physically separated from the electronic module (9b) and is combined, at least with the core (6), to form a single-piece structural unit which is surrounded by a common anti-corrosion layer (26).
