Solution Overview

Problem

Conventional maglev power generators experience power loss and reduced rotational stability due to friction and vibration in the transmission mechanism, which existing maglev transmission mechanisms fail to adequately address.

Innovation Solution

The maglev power generator incorporates a frame with a transmitting shaft suspended within it, connected to axial and radial vibration-proof sets and maglev assemblies, providing magnetic forces to prevent deviation and rotationally stabilize the shaft, minimizing power loss through magnetic repulsion and attraction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of energy

If a conventional transmission mechanism with a rotatable shaft is used, then mechanical energy can be transmitted, but friction causes power loss and reduces rotational stability

Engineering Contradiction:

Improvepower lossVSAvoidrotational stability

Core Design Contradiction:

Loss of energyVSReliability

Solution Approach 1:

The patent replaces the conventional mechanical transmission mechanism with a magnetic field-based transmission system. The magnetic driving assembly generates a magnetic field that directly drives the magnetic driving disc attached to the transmitting shaft, eliminating the need for mechanical contact and friction-based transmission. This substitution resolves the contradiction by removing the source of friction-induced power loss while maintaining transmission functionality through magnetic coupling.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces magnetic fields as an intermediary between the power source and the transmitting shaft. The magnetic driving assembly creates a magnetic field that acts as a mediator to transmit rotational force without direct mechanical contact. This intermediary magnetic field enables power transmission while avoiding the friction and wear associated with traditional mechanical shafts and bearings.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Loss of energy

If a maglev transmission mechanism is used to reduce friction, then power loss is reduced, but vibration in axial and radial directions reduces rotational stability

Engineering Contradiction:

Improvepower lossVSAvoidrotational stability

Core Design Contradiction:

Loss of energyVSReliability

Solution Approach 1:

The patent employs magnetic suspension assemblies that generate opposing magnetic forces to counterbalance the weight and vibration forces acting on the transmitting shaft. These assemblies create upward magnetic lift forces that counteract gravitational force and downward vibration forces, while radial magnetic forces counteract radial vibrations. This counterbalancing approach stabilizes the shaft rotation while maintaining the frictionless maglev transmission benefits.

Inventive Principle:

Principle #8Anti-weight (Counterweight)

Solution Approach 2:

The patent actively manages vibration through magnetic suspension assemblies that detect and counteract vibrational forces. The assemblies generate controlled magnetic forces that oppose unwanted axial and radial vibrations of the transmitting shaft, converting vibrational energy into stabilizing magnetic forces. This approach maintains rotational stability while preserving the low-friction maglev transmission characteristics.

Inventive Principle:

Principle #18Mechanical vibration

AI summary

A maglev power generator has a frame, a transmitting shaft, two electricity generating sets, two axial vibration-proof sets, two maglev assemblies, and two radial vibration-proof sets. The transmitting shaft longitudinally extends within the frame. The two electricity generating sets, the two maglev assemblies, and the two radial vibration-proof sets are connected to the transmitting shaft. Each axial vibration-proof set contacts a respective end of the transmitting shaft. The transmitting shaft suspends within the frame and is able to rotate without contact with the frame. The axial vibration-proof sets, the maglev assemblies, and the radial vibration-proof sets provide the transmitting shaft with magnetic forces radially and axially to prevent the rotating transmitting shaft from deviation. Therefore, the transmitting shaft is able to rotate with minimum power loss. The axial vibration-proof sets and the radial vibration-proof sets effectively offer a good vibration-proof function to let the transmitting shaft rotate stably.
