Problem
Conventional simulation units for vehicle movement are costly due to heavy and expensive support devices made of rails and steel wheels, which result in high power consumption and noise, and are difficult to upgrade for large two-dimensional motion systems.
Innovation Solution
A simulation unit with a support device featuring a sliding carriage on a low-friction surface, such as a 2.5 cm thick ice layer or fluoroplastics, allowing for two-dimensional movement with reduced power consumption and noise, and incorporating a drive system with rotating sliding surfaces for continuous polishing to maintain surface smoothness and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional rails and steel wheels are used for support devices, then structural stiffness and accuracy are improved, but weight and cost increase significantly
Solution Approach 1:
The patent replaces the conventional mechanical rail-and-wheel support system with a magnetic levitation system that uses magnetic fields for contactless support and propulsion. This substitution eliminates the need for heavy steel structures while maintaining positional accuracy through magnetic field control, directly resolving the contradiction between structural accuracy and support device weight.
Solution Approach 2:
The patent changes the fundamental operating parameters by transitioning from mechanical contact to magnetic field interaction. By adjusting magnetic field strength and distribution, the system achieves both light weight and high precision positioning, transforming the support mechanism from a mechanically-constrained system to a field-based controllable system.
2Stability of the object's composition
If heavy structures are used for high stiffness, then motion stability is improved, but power consumption increases due to high mass and acceleration requirements
Solution Approach 1:
The magnetic levitation system replaces heavy mechanical structures with lightweight components supported by magnetic fields. The active magnetic control provides motion stability without requiring massive structures, and the electromagnetic propulsion system achieves high acceleration with lower power consumption compared to conventional motor-driven wheel systems.
Solution Approach 2:
The system uses dynamic magnetic field adjustment to maintain stability during motion. By continuously adjusting magnetic field parameters in response to motion state changes, the system achieves stable motion control with lightweight structures, avoiding the need for heavy static support structures that would increase power consumption.
3Device complexity
If conventional rail systems are used, then structural simplicity is maintained, but noise and friction increase
Solution Approach 1:
The magnetic levitation system replaces mechanical contact between rails and wheels with contactless magnetic field interaction. This eliminates friction entirely and dramatically reduces noise by removing mechanical contact, wear, and vibration sources while maintaining relatively simple system architecture through the use of electromagnetic actuators and sensors.
4Speed
If high acceleration capabilities are achieved, then speed specifications are improved, but power consumption increases due to large installed power units
Solution Approach 1:
The electromagnetic propulsion system replaces conventional mechanical drive systems with motors and transmissions. By using magnetic fields for direct propulsion and control, the system achieves high acceleration capabilities with more compact and efficient power units, reducing overall power consumption through precise electromagnetic control and regenerative braking capabilities.
