Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The mechanical side guide in magnetic levitation railways experiences high material stress and potential harm to passengers or goods due to direct force transmission during engagement, which can lead to jerky movements and increased risk in the event of energy supply failure.
Innovation Solution
A levitation frame with a movable guide element connected via a joint to the levitation frame, incorporating spring and/or shock absorber elements to absorb forces and dampen vibrations, and a hinged joint allowing unidirectional movement in the transverse direction, reducing jerky engagement and distributing forces effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a mechanical side guide with direct force transmission is used, then the lateral guidance function is achieved, but high material stress and jerky movements occur
Solution Approach 1:
The patent introduces spring elements and shock absorber elements between the guide element and the levitation frame to cushion forces before they are transmitted to the structure. The spring elements absorb elastic deformation energy while shock absorber elements dampen vibrations, thereby reducing material stress during engagement while maintaining the lateral guidance function.
Solution Approach 2:
The patent uses spring elements and shock absorber elements as intermediary components between the guide element and the levitation frame. These intermediaries absorb and dampen forces, preventing direct transmission of high stresses to the structural components while still allowing the guide element to perform its lateral guidance function.
2Reliability
If a mechanical side guide with direct force transmission is used, then the lateral guidance function is achieved, but harmful effects on passengers or goods increase
Solution Approach 1:
The spring elements and shock absorber elements are positioned to cushion forces before they can be transmitted to passengers or goods. The shock absorber elements specifically dampen vibrations and reduce harmful effects on the cargo and passengers during engagement events.
Solution Approach 2:
The spring and shock absorber elements act as intermediaries that isolate the levitation frame from direct force transmission. This mediation prevents harmful vibrations and shocks from being transmitted to passengers or goods while maintaining the essential lateral guidance function.
3Ease of operation
If a movable guide element via joint is used, then jerky engagement is reduced, but device complexity increases
Solution Approach 1:
The patent makes the guide element movable relative to the levitation frame through a joint connection, allowing it to move in the transverse direction. This dynamic capability enables the guide element to engage smoothly without jerky movements, improving ease of operation while the added complexity is managed through standardized joint designs.
Solution Approach 2:
The patent divides the side guide system into separate functional components: the guide element, the joint, and the spring/shock absorber elements. This segmentation allows each component to be optimized independently and simplifies the overall system by distributing functions across separate elements rather than requiring a monolithic complex structure.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution reduces material stress and enhances safety by minimizing jerky movements and shock absorption, ensuring stable and safe vehicle operation even in emergency scenarios by distributing forces and reducing engagement stress.
Implementation Method 1
A spring element can absorb a portion of the force acting on the vehicle
Implementation Method 2
The shock absorber element can be designed as a hydraulic shock absorber or frictional damper
Implementation Method 3

Implementation Method 5
They are based on the principle of keeping a track-bound vehicle levitated by the repelling and/or attracting action of a magnetic field
Implementation Method 6
A drive of the vehicle is generally likewise designed to be non-contact. One example of such a drive is a linear motor
