Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The superconducting magnetic suspension train's weight is increased due to the need for low-temperature cooling liquid containers, which complicates the walking mechanism and reduces suspension efficiency, necessitating a simplified structure that integrates suspension, drive, and guidance functions while minimizing weight.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If superconducting magnets and low-temperature cooling liquid containers are mounted on the train, then magnetic suspension force is generated, but the weight of the walking mechanism increases
Solution Approach 1:
The patent combines the suspension function and steering function into a single integrated bogie structure. The upper frame and lower frame are hinged together to form a unified suspension-steering mechanism, eliminating the need for separate steering devices and reducing overall weight while maintaining suspension capability
Solution Approach 2:
The bogie structure serves multiple functions simultaneously: it provides magnetic suspension through superconducting magnets, enables steering through the hinged frame configuration, and supports the train body. This multi-functionality reduces the number of separate components needed, thereby reducing weight
2Temperature
If multiple devices for containing low-temperature cooling liquid are mounted on the train, then superconducting magnets can be powered, but the structure of the walking mechanism becomes complex
Solution Approach 1:
The patent integrates the cooling liquid containment system directly into the bogie structure. The lower frame incorporates mounting positions for cooling liquid containers, merging the thermal management system with the mechanical suspension structure, thereby simplifying overall system complexity
Solution Approach 2:
The cooling liquid containers are positioned within the bogie structure in a nested arrangement, where the containers are housed within the frame configuration. This nesting approach optimizes space utilization and reduces structural complexity by avoiding separate external mounting systems
3Ease of operation
If a separate steering mechanism is added to the bogie, then steering control is improved, but the weight and complexity of the walking mechanism increase
Solution Approach 1:
The hinged connection between the upper frame and lower frame provides both suspension and steering functions through a single structural arrangement. The hinge allows the bogie to pivot for steering while simultaneously providing the suspension mechanism, eliminating the need for separate steering components and reducing weight
Solution Approach 2:
The suspension mechanism and steering mechanism are merged into a single hinged bogie structure. The same hinge connection that enables suspension also provides steering capability, thereby achieving steering control without adding separate steering components that would increase weight

Function Achieved in This Case
The design effectively reduces the weight of the walking mechanism, enables higher speeds (above 500 km/h), and enhances suspension force by allowing more low-temperature liquid containers, thereby improving the overall efficiency and stability of the magnetic suspension train.
Implementation Method 1

Implementation Method 2
The EDS mounts superconducting magnets at a bottom of the train (placed in a liquid nitrogen or liquid helium storage container) and lays a series of aluminum ring coils at two sides of a rail. When a train runs, the coil (the superconducting magnet) on the car is powered on to generate a strong magnetic field
