Magnetic Levitation Vehicle Sequential Magnet Activation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Magnetic levitation vehicles require high power for lifting and lowering processes due to the need for simultaneous activation of all supporting magnet units, leading to increased weight and costs, as well as additional charging cycles for on-board batteries.
Innovation Solution
Sequential activation and deactivation of individual support magnet units, reducing the power requirement by distributing the load across multiple steps, with each step requiring only a fraction of the total power needed for simultaneous activation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If all supporting magnet units are activated simultaneously for lifting and lowering, then the lifting and lowering processes can be completed, but the power requirement increases significantly
Solution Approach 1:
The patent divides the supporting magnet units into multiple groups that are activated or deactivated sequentially rather than simultaneously. This segmentation allows the total power requirement to be distributed across time, reducing the peak power demand while maintaining the overall lifting and lowering functionality.
Solution Approach 2:
The patent implements periodic activation and deactivation of magnet unit groups during the lifting and lowering processes. By using multiple phases or steps with time offsets, the system achieves the required mechanical work through periodic power application rather than continuous full-power operation.
2Weight of moving object
If all supporting magnet units are activated simultaneously, then lifting and lowering can be achieved, but on-board power supplies must be dimensioned larger increasing vehicle weight and costs
Solution Approach 1:
By segmenting the magnet unit activation into sequential groups, the patent reduces the peak power demand, allowing on-board power supplies to be smaller and lighter while still providing sufficient power for the lifting and lowering operations.
Solution Approach 2:
The patent activates magnet units in a predetermined sequence before the actual lifting or lowering begins. This preliminary staged activation allows the system to prepare gradually, reducing the instantaneous power requirement and enabling smaller power supply components.
3Duration of action of moving object
If all supporting magnet units are activated simultaneously, then lifting and lowering processes can be completed, but additional charging cycles are required for on-board batteries
Solution Approach 1:
The periodic, multi-phase activation pattern reduces peak power consumption, allowing battery-powered systems to operate within available energy reserves for longer periods, thereby extending operational duration between charging cycles.
Solution Approach 2:
The patent dynamically adjusts the power consumption profile by varying the activation sequence and timing of magnet units. This dynamic power management optimizes energy usage during lifting and lowering operations, extending battery life and reducing charging frequency.
