Description

BACKGROUND

Centrifugal force is the apparent force that draws a rotating body away from the center of rotation. “Centrifugal force” is caused by the inertia of the body moving in an arc or circle. In Newtonian mechanics, the term centrifugal force is used to refer to the inertial force (also called a “fictitious” force) observed in a non-inertial reference frame. The concept of centrifugal force is applied in rotating devices such as centrifuges, centrifugal pumps, centrifugal governors, centrifugal clutches, etc., as well as in centrifugal railways, planetary orbits, banked curves, etc.

DETAILED DESCRIPTION

Stated broadly various aspects and embodiments are directed to lift assist systems and methods that employ the angular momentum generated by drive bodies travelling along curvilinear guide tracks to provide lifting force. The guide tracks and drive bodies can be positioned on heavy objects to provide lift reducing an overall energy requirement associated with moving such heavy objects.

According to one embodiment, the system uses a plurality of connected curved guide portions positioned to maximize lift generated by the track. In various embodiments, one or more drive bodies are moveably connected to the guide track. The drive bodies are configured to accelerate along the guide track increasing the lift generated as the drive bodies traverse the guide track. In some embodiments, the guide track includes a plurality of magnetic sections that operate on magnetic sections of the drive bodies. In further embodiments, either of the guide track and drive body can include fixed and/or electromagnets that can be configured to force the drive bodies along the guide track. For example, the drive bodies can be constructed of fixed magnets that provide at least two polarity sections of the drive body. The polarity associated with the guide track can be manipulated by application of electricity to cause the drive bodies to move along the guide track.

In some embodiments, a lift system can include tilt sensors and/or accelerometers to evaluate positioning and/or orientation of the lift system. In one example, the system can include a control unit configured to manipulate the speed and/or spacing of the drive bodies (e.g., magnetic cars) to compensate for any tilt or lateral forces.

References to “or” may also be construed as inclusive so that any terms described using “or” may indicate any of a single, more than one, combinations of selective ones, and all of the described terms.

FIG. 1 is a view 100 of the circular rotation of a ball 102 (e.g., at positions A-H) with mass M around a center 104 at a speed S, which creates angled speed (e.g., shown by arrows M-T) and centrifugal force=M×S in all directions (e.g., at I-L). As shown, the circle of ball trajectory remains static due to force equalization.

FIG. 2 is a view 200 of a rotation of a ball 202 with mass and speed S (e.g., along line 206) in a circle cut out section of 60°, from −30° to +30° around a centre 204, creates centrifugal force=M×S in the direction of the O degree axis (e.g., at 208) for a short period provided that no other opposing centrifugal force exists.

FIG. 3 is a view 300 of rotation of a ball 302 with mass M and speed S in a circle cut out section of 60° degrees around a center 304 (0°), which creates directional centrifugal force M×S in the direction of 0° axis (e.g., 308) for a short period. Repetition of such movement in a pendular fashion (e.g., shown by arrows 310 and 312) creates bursts of mechanical centrifugal force in the same direction.

FIG. 4 is a view 400 of rotation of 2 balls (e.g., 402 and 404) on 2 pendulums, where each ball (402 and 404) travel along paths 406 and 408 in reverse directions so that if one pendulum is at 0° degrees the other is at 30°. If speed is at a maximum at 0°, the apparent centrifugal force is at a minimum where the pendulum is at either +30 or −30.

FIG. 5 is a graphical view 500 of centrifugal force generated by the pendular movement of one pendulum between +30° and −30° around an origin at 0°. The force is at a minimum when the ball is either at the +30 or −30 angles. FIG. 6 is a graphical view 600 of centrifugal force created by 2 pendulums (e.g., FIG. 4) moving in opposite directions around an origin at 0° axis in a range of +30 to −30 in a way that when the first pendulum is at min force (+30°) the other pendulum is at max force (+ or −0°) to offset the drop in force. In other embodiments, multiple pairs of drive bodies, and the motion of individual elements can be synchronized to achieve maximum lift between a first pair of individual elements. The motion of a second pair of drive bodies can be offset so that when the first pair of drive bodies reach a minimum lift, the second pair of drive bodies is at a maximal lift position. In other embodiments, the system can control any number of drive bodies individually.

FIG. 7 is a view 700 of opposing pendulums moving back (e.g., traveling on paths 702A-702B and 704A-704B respectively) and forth at high frequency around the 0° axis (e.g., wherein the operation of the pendulums are staged to be perpendicular to ground) creates continuous centrifugal force both at the direction of 0° upward (e.g., shown by arrows 706 and 708) with minimum loss of force. FIG. 8 is a view 800 of magnetic rail 802 which can drive a car 804 along a path defined by the rail 802. In some embodiments, the rail is configured in a circle and by changing the polarity of the rail 802 magnets 806A-I or the car magnets 808A-B the car is driven around the circumference of the rail 802. According to some embodiments, the speed of the car can be increased by increasing the rate of polarity change of the magnets 806A-I and/or 808A-B. Further, the direction of movement of the car can also change by changing polarity of the magnets.

FIG. 9 is a view 900 of magnetic rail 902 in a curved configuration with a magnetic car 904 moveable around the circumference of the rail 902. The magnetic car 904 is configured to travel back and forth in a circular cut out portion shown (e.g., approximately 60° of movement between +30, −30 degrees of freedom. The angular speed of the car 904 creates centrifugal force in the direction of 0° and perpendicular to the movement along the rail. According to various embodiments, either one or both of the rail and magnetic car can include a plurality of electromagnetic elements configured to provide electromagnetic fields and respective polar magnetic fields (e.g., illustrated by N and S for North and South polar fields). The fields provided by the plurality of electromagnetic elements can be manipulated to control the movement of the car 904 along the rail 902 (e.g., speed, direction, etc.).

FIG. 10 is a view 1000 of the movement of two magnetic cars 1002 and 1006 on two rails 1004 and 1008 having the same curvature and dimensions (e.g., from −30 to +30). Assuming the cars 1002 and 1006 had the same mass and speed, their respective motion in opposite directions over the curved rails in (e.g., through 60° degree of freedom+30 to −30 around 0° axis) generates centrifugal force in the 0° axis direction. According to some embodiments, by synchronizing the movements of the two cars 1002 and 1006 so that they move along opposite portions of their respective curved rails (e.g., lower left portion of curved rail and lower right portions of curved rail) and in opposite direction the combined forces are directed along arrow 1010. According to various embodiments, a plurality of curved rail portions can be constructed or the same dimensions and oriented such that cars travelling along the rails generate a uniform force.

FIG. 11 is a view 1100 of a car 1102 travelling in a circle along path 1104 and the centrifugal force generated at 1106A-D, which is equal in all directions. FIG. 12 is a view 1200 of the lower half of the circle of FIG. 11, if it is flipped up. As ball 1202 travels along rail 1204 the continuous movement of the ball 1202 generates, in aggregate, unidirectional centrifugal force (e.g., 1206A-B). As shown in FIG. 12, the ball 1202 travels along the curvature of each section. The modification of the circle of FIG. 11 to obtain the configuration of FIG. 12, can be analogized to the curvature made by the outer circumference of a taco shell, where two opposed curved portions are joined together.

FIG. 13A is a view 1300 showing a first cut-out portion 1302 and a second cut-out portion 1304 of a curvature track 1312. 1302 and 1304 illustrate portions of the complete track 1312 which provides opposed curved portions along which a plurality of magnetic cars and/or bodies 1314 can travel in a complete loop. According to one embodiment, the track 1312 and/or respective ones of the plurality magnetic cars (e.g., 1314) include a plurality of electromagnetic portions. The electromagnetic portions can be controlled by a control unit 1310. The control unit can be configured to manipulate the magnetic fields generated at the plurality of electromagnetic portions. In one example, the control unit 1310 manipulates the polarity (e.g., N, S, off) of the electromagnetic portions to force the magnetic cars (e.g., 1314) along the track 1312. In some examples, the control unit can selectively apply power to the electromagnetic portion (e.g., from power supply 1308). The control unit 1310 can be configured to turn on or off the electromagnetic portions and/or reverse the polarity of the magnetic fields produced. According to one embodiment, the track 1312, magnetic cars (e.g., 1314) control unit 1310 and power supply 1308 can be fabricated together to form a lift assist device 1306. In one example, as the magnetic cars travel along the track 1312 the lift assist device creates and upwardly directed force. In further examples, as the velocity of the magnetic cars is increased the lifting force generated overcomes the weight of the lift assist device 1306, and the lift assist device can be used to affect a lifting force required to move heavy objects. FIG. 13B is a view 1350 of another embodiment of a magnetic track 1352 and an exploded view of a portion of the track at 1354.

FIG. 14 is a view 1400 of another embodiment of a magnetic rail having a spiral configuration where alternating curves of the magnetic rail generate a centrifugal upward force as magnetic cars travel along the rail. According to one example, the centrifugal force generated is directly proportional to speed of the magnetic cars. In another example, the force generated can be calculated from the equation force (F)=mass of car times the speed of car on the curve. In some embodiments, the directionality of the force is calculated based on curvature of the rail and the position of the magnetic car on the rails. The calculation of force can be stored on the system and the system can manipulate the drive bodies to match velocity and position to already calculated values. The system can also be configured to access stored force calculations to manage positioning and speed of the magnetic cars travelling along the rail. According to some embodiments, responsive to determined force values (e.g., dynamically calculated or stored) the system is configured to manipulate positioning and/or speed of the magnetic cars.

FIG. 15 is a view 1500 of another embodiment of a lift device and an exploded view of a cut-out portion 1508 of magnetic track 1502 of the lift device. According to one embodiment, the lift device includes magnetic cars (e.g., 1510). In some embodiments, the motion of the cars (e.g., 1510) can be controlled by a control unit 1504 that manages delivery of power (e.g., 1506 power supply) to electromagnetic portions of the track 1502. As shown, each car generates its own centrifugal force as it travels along the track 1502.

FIG. 16 is a view 1600 of another example embodiment having a circular magnetic rail 1602 carrying multiple magnetic cars (e.g., 1606 and 1608). As the cars move along the rail 1602 (e.g., along paths 1604), each car creates its own upward centrifugal force (e.g., 1610A-C).

FIG. 17 is a view 1700 of another example embodiment including a curved magnetic rail portion, including a plurality of electromagnetic elements. Magnetic cars travel along the rail under the influence of manipulated magnetic fields. According to some embodiments, either of the rail or the cars can include fixed magnets and/or fixed magnetic fields of fixed polarity, which can be influenced by manipulation of electromagnetic fields proximate to the fixed magnetic fields. According to some examples, the curved portions is a cut out of a circle approximately between eleven and one o'clock (e.g., 1702). FIG. 18 is a view 1800 of the movement of a magnetic car on section of rail whose path is a cut out (11-1 o'clock) of a circle. Traversing the section back and forth at a high speed creates upward centrifugal force.

FIG. 19 is a view 1900 of another embodiment having six magnetic cars (e.g., 1902-1912) moving on a continuous magnetic rail 1914 having a spiral configuration. The cars (e.g., 1902-1912) are configured to travel at a high speed along the rail 1914, creating a lifting/upward centrifugal force as they move along the curved portions of the rail.

FIG. 20 is a view 2000 of another embodiment having two circular sections with a reciprocal magnetic rail. The cars and rail are configured for driving multiple magnetic cars at a continuous high speed on the two rails, and with each pass over any of the curved portions an upward/lifting centrifugal force is generated. FIG. 21 is a view 2100 of another embodiment of a lift system containing an array of multiple magnetic curved spiral sections driving multiple magnetic cars at high speed which creates enough upward/lifting force that can overcome the weight of the system and/or gravitational effects on the system.

FIG. 22 is a view of another embodiment having three lift devices (e.g., 2202, 2204, and 2206) which can be attached to a heavy object to decrease the objects effective weight (e.g., reducing the weight of a car). FIG. 23 is a view 2300 of another embodiment having two lift devices operating to lift a body with a weight (w) against the operation of gravity (G) where F_g>G; C_n×C_3>G. F_g=number of magnetic cars (C_n)×speed of cars (C_s). FIG. 24 is a view 2400 of another embodiment of a lift assist system configured to generate magnetic upward centrifugal levitation, in order to reduce the effects of gravity by creating upward Force F_g.

FIG. 25 is a view 2500 of another embodiment including a fixed magnetic car sliding on a magnetic rail that contains successive electromagnets configured to drive the magnetic car over the rail by changing the polarity of the electromagnets on the rail. For example, by creating attractive force local to the car (e.g., opposing magnetic pole in front of the car and repelling force (similar magnetic poles)) behind the car, the net effect is a forward movement of the car. In some embodiments, the polarity of the magnets can be manipulated by a control unit to increase the frequency of the magnetic polarity changes and increase speed.
