Human body massager with magnetic field generator

What is this patent about?

’329 is related to the field of therapeutic massage devices, specifically those utilizing magnetic induction to stimulate blood circulation and relax muscle tissue. Traditional massagers often rely on rigid mechanical components that can cause discomfort or injury, or static magnets that provide limited physiological engagement. This invention seeks to bridge the gap between passive magnetic therapy and active mechanical stimulation by using dynamic, fluctuating magnetic fields to interact with the body.

The underlying idea behind ’329 is the creation of a spatially and temporally varying magnetic field generated by moving permanent magnets rather than stationary coils. By physically rotating a set of magnets with alternating polarities and varying strengths or distances relative to the user, the device creates a complex, shifting magnetic flux. This movement induces deeper stimulation in the circulatory system and can be used to drive secondary, free-floating massage elements within a liquid medium, providing a multi-sensory therapeutic effect.

The claims of ’329 focus on a specific mechanical arrangement for generating this variable field, featuring a motor-driven rotating wheel positioned beneath a body-supporting surface. The independent claims require the magnets to be arranged with alternating polarities around the wheel's center. Crucially, the claims specify that the variability is achieved either by using magnets of different magnetic strengths or by mounting the wheel in a sloping position so that the distance between the magnets and the user changes constantly during rotation.

In practice, the massager functions as a versatile platform that can be configured as a dry footrest or a liquid-filled spa basin. When configured as a spa, the rotating magnetic field acts as a non-mechanical driver for encapsulated magnetic cores dropped into the water. These elements tumble and dance in response to the shifting flux, physically striking the user's skin to provide a gentle, randomized tactile massage that is safer and more fluid than fixed mechanical rollers.

This approach differentiates itself from prior art by moving away from static magnetic pads or simple vibrating motors. By utilizing a slanted rotational axis or heterogeneous magnet strengths, the invention ensures the magnetic flux is never uniform, preventing the body from habituating to the stimulus. Furthermore, the integration of this magnetic drive system with traditional hydrotherapy features—such as bubble generators and heaters—creates a synergistic effect where the magnetic field enhances both the biological response and the physical movement of the water.
