In this paper, a new type of positioning mechanism for superconducting levitation system is proposed. The principle of this mechanism is to use an impact driving energy against a pinning force for positioning. When a permanent magnet is levitating over a superconductor, the pinning force works between a superconductor and the levitated permanent magnet tightly. If the system has an impact driving energy against the pinning force and the impact force is larger than the pinning force, the permanent magnet will move to next pinning points. If an impact force for the superconductor works to the system, the movement of the superconductor and the magnet are different. The movement of the superconductor is larger than the movement of the magnet. This movement means that the pinning effect has been broken and the permanent magnet has been slipped. After sticking both objects by the pinning force, the superconductor returns to the original position slowly and the levitated magnet's position is slightly changed. The repetition of the impact force and its return to the original position makes the levitated magnet be positioned.
