Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a weight control system in which weight energy of an object is partially converted into compression energy by using a spring while the weight energy is absorbed to be converted into other form of energy including, for example, electrical energy or mechanical energy depending on usage for recycling purposes.

2. Description of the Related Art

Generally, in order to reduce the weight of an object, various techniques can be used such as separating an unnecessary part to be removed (e.g., separation of moist from dried sludge) evaporating a part or all of the object to render the weight light (e.g., conveying water in the form of steam), using light material to create buoyancy (e.g., aeroscraft, a balloon, etc.), or using buoyancy assisted lift (e.g., ships, airplanes, etc.). In this manner, weight reduction effect can be achieved although the volume of the object can be increased when the object is vaporized under a high temperature. However, vaporization is advantageous in that it is easy to convey the vaporized object, e.g., water vapor.

However, it is impossible to reduce mass itself because the mass, unlike weight, is invariable. Meanwhile, weight is expressed as W=(mass)×(acceleration of gravity), wherein the acceleration of gravity is 9.8 m/sec². Therefore, it is necessary to reduce the acceleration of gravity to reduce the weight. However, the gravitational acceleration cannot be reduced unless the mass of the earth is reduced or the object moves to a high altitude, i.e., a far distance away from the center of the earth. Therefore, the gravitational acceleration cannot be reduced itself. Instead, a gravity force can be offset by using other source of force such as magnetic or electromagnetic field.

In other words, it is possible to control the weight of the object by partially converting weight energy thereof into other type of energy.

Namely, in order to offset the gravity force, a different source of force such as, for example, magnet, electromagnet, a hydraulic cylinder, a vacuum cylinder, lift, or buoyancy can be used. Herein, the present invention employs a method of using a magnet and an electromagnet, which shows excellent efficiency in offsetting the gravity force.

According to the present invention, a current logistics system can be radically improved as well as enormous future demands can be created from private, public and military sectors.

SUMMARY OF THE INVENTION

DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS

Exemplary embodiments of the present invention are described with reference to the accompanying drawings in detail. The same reference numbers are used throughout the drawings to refer to the same or like parts. Detailed descriptions of well-known functions and structures incorporated herein may be omitted to avoid obscuring the subject matter of the present invention.

In a magnetic circuit including a permanent magnet, the permanent magnet has a permeance coefficient in a range from zero to infinity and its operating point is located on a demagnetization curve in a second quadrant, as shown in FIG. 11. When the magnetic circuit including the permanent magnet has the configuration shown in FIG. 12, the permeance coefficient for predicting and calculating the operating point of the permanent magnet is obtained by a method described below.

The term “magnet/electromagnet,” used herein, refers to at least one of magnet or electromagnet that creates a magnetic or electromagnetic field.

For illustrative purposes, it is assumed that, in the magnetic circuit in FIG. 12, a magnetic flux density and a magnetic field are uniform, a cross sectional area and a length are constant, and a magnetic characteristic of a magnet, i.e., magnetic permeability, is constant. According to Ampere's circuital law, a magnetomotive force of the magnetic circuit is expressed as the following Equation 1 and can be rewritten as the following Equation 3 by using a magnetomotive force loss coefficient f, which is expressed as the following Equation 2.

H _m I _m +H _c I _c +H _g I _g+0  [Equation 1]

H _m I _m /H _g I _g =f  [Equation 2]

H _m =−f(I_g/I_m)H_g  [Equation 3]

Meanwhile, Equation 4 in the below can be deduced from magnetic flux continuity condition of the magnetic circuit including the permanent magnet and Equation 6 can be deduced by using a magnetic flux leakage coefficient expressed in Equation 5.

B _m A _m =B _g A _g +Φ ₁  [Equation 4]

σ₁=B_mA_m/B_gA_g  [Equation 5]

B _m =σ ₁(A_g/A_m)B_g  [Equation 6]

Based on the Equations 3 and 6 in the above, the permeance coefficient for determining the operating point of the permanent magnet can be obtained as the following Equation 7.

B _m /H _m=−(σ₁/f)(A_g/A_m)(l_m/l_g)=p_c  [Equation 7]

Thus, the permeance coefficient is inverse proportionate to the magnetomotive force loss coefficient f and is proportionate to the magnetic flux leakage coefficient σ₁, and is expressed with a function of the cross sectional area and the length of the permanent magnet and a pore. As shown in Figure a, the operating point of the permanent magnet in the magnet circuit is determined as a crossing point of a straight line of the permeance coefficient, p_c, and the demagnetization characteristic curve of the permanent magnet. When the magnetic flux density at the operating point is determined, a void magnetic flux density can be calculated by using Equation 6.

However, in reality, it is difficult to calculate the magnetomotive force loss coefficient for the magnetic flux leakage coefficient σ₁ of an electronic appliance in consideration of magnetic saturation. Therefore, a numerical analysis such as a finite element method can be used. The operating point of the permanent magnet can be varied depending on the existence of a reaction magnetic field externally applied or operating temperature, even if the permeance coefficient is constant.

Considering the above characteristics, the system can have a detailed configuration as shown in FIG. 5 by properly arranging the displacement of the magnet and the electromagnet, and considering the strength of magnetic field. When a power is supplied in an initial state to the system configured as shown in FIG. 5, an induced current is generated in an internal core 16 and a coil 15, and a strong and centrifugal magnetic field is generated between a pillar portion of a bottom plate 1 and a second upper plate magnet/electromagnet 12 and an upper plate housing 13, wherein the magnetic field is applied in a downward direction along the pillar portion of the bottom plate 1 and in a direction perpendicular to a centrifugal force. Due to forces produced by the magnetic field applied in two directions, an upper plate 9 and a first upper plate magnet/electromagnet 10, which are positioned in a lower portion of the system, are caused to rotate in the magnetic field, similarly to an operation of an automatic transmission of an automobile. Here, a first magnet/electromagnet 2, which is a complex magnetic flux, and a second magnet/electromagnet 3, a third circular magnet/electromagnet 4 and a bottom base 6, and a spindle 7 and a spindle cover 8 are engaged with each other to rotate, thereby generating a strong centrifugal magnetic field in an opposite direction.

Any object has its own natural frequency, which is a rate at which the object resonates, and the natural frequency of the object is determined according to its stiffness and mass. Specifically, the natural frequency is expressed as ½π (stiffness/mass)½. Therefore, when the stiffness is increased four times, the natural frequency is increased twice, and when the mass is increased four times, the natural frequency is decreased twice. When the natural frequency of the object matches with an outside frequency, the object can be significantly distorted. The present invention utilizes such phenomenon in a magnetic field.

When the two magnetic fields generated in the system engage and interrupt each other, overlapping of the magnetic fields occurs such that an upper cover 17 is lifted by a repulsive force caused by the respective magnetic fields of an upper portion and a lower portion of the system. Therefore, a lifting force is applied to the assembly of an upper spring guide fixing plate 23, a compression spring 28, a compression spring washer 29, a lower spring guide fixing plate 22, a fixing bolt 21 positioned between the upper spring guide fixing plate 23 and the compression spring 28, a fixing nut 20 between the lower spring guide fixing plate 22 and the compression spring 28, and an upper damper 19. Accordingly, the spring begins to be compressed and gradually enters to an anti-gravity state.

When a compression force is applied to a part of the weight control system, the compression force is conveyed to an external through an upper portion piston 25, a piston cap 26, and an external fixing plate 27, thereby reaching a target weight of the object. By repeating the above operation, a desired weight of the object can be achieved.

Thus, according to the present invention, the compression energy of the spring is partially converted into an electrical energy to be recycled based on the weight energy contained in the object. Alternatively, the compression energy of the spring can be converted into a mechanical energy depending on usage.

A piezoelectric element is attached to the upper damper 19 to produce electrical energy based on mechanical vibration applied thereto and the compression energy of the spring. In this manner, when the upper cover 17 is lifted to apply pressure to the upper damper 19, the piezoelectric element attached to the upper damper 19 produces electricity due to stress applied thereto.

In addition, a central processing unit (CPU) that is built in a system control box 30 of FIG. 3 automatically controls an electric power level such that, when an electric power needs to be charged in the system, a red LED light is turned on, a warning sound is generated, and power begins charging. Also, a text, an e-mail or a voice message can be sent to a mobile phone designated by a user or any other reachable device to notify the user of the power charging of the system. Further, the system can be remotely controlled so that the user can operate the system at a desired time. When the power charging of the system is completed, a green LED light is turned on, a system motor stops operating, and the text, the e-mail or the voice message is sent to the mobile phone designated by the user or any other reachable device to notify the user of the completion of the power charging of the system. Therefore, the operation of the system can be monitored at any time and from any place. Further, the user has an option to choose whether to operate the system depending on necessity.

To this end, the system control box 30 includes a power plug 31, a power jack 32, a charge green light 33, a charge red light 34, a switch 35, a printed circuit board (PCB) 36 for the CPU, an antenna 37 and an external connection jack 38.

The upper spring guide fixing plate 23, the lower spring guide fixing plate 22, a housing rib 24, the upper piston 25, the piston cap 26, and an external fixing plate 27 are exposed to an external impact, and therefore, a material having higher abrasion resistance, higher hardness and higher elasticity can be used.

The assembly of a lower electric electromagnet portion is completed by assembling the upper plate internal core 16 and the coil 15 and by engaging the upper cover 17 with the upper plate housing 13 by using a fixing bolt 18 positioned therebetween.

On the top thereon, the housing rib 24, the upper portion piston 25, and the piston cap 26 are assembled in a consecutive order, and the external fixing plate 27 is mounted thereon. A housing 5 is mounted to finish the external appearance of the assembly.
