Description

AN ENERGY STORAGE SYSTEM AND A PORTABLE DEVICE TO STORE ENERGY USING AN ELASTIC MEMBERTECHNICAL FIELD

[0001] The embodiments of the present disclosure generally relate to the field of power storage systems. More particularly, the present disclosure relates to the system and device implemented for storing potential energy using a plurality of elastic members (hereinafter ‘elastic members’).BACKGROUND

[0002] Background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.

[0003] The growing need for sustainable energy sources is driven by concerns about dwindling fossil fuels and environmental protection. Existing renewable energy options like solar, wind, and traditional hydropower have limitations. Large-scale hydropower projects can be expensive, technically challenging, and disrupt water ecosystems. Nuclear power poses safety risks, while wind and solar have limitations related to space constraints and weather dependence.

[0004] Further, several problems are associated with the old technologies, including fuel, pollution, site conditions, efficiency, electric power storage, complicated systems, and prohibitively expensive construction. The present breakthrough generates clean, safe, and economical power using the potential energy of the elastic member. The invention provides a technique for offsetting or decreasing carbon dioxide emissions from conventional carbon- containing fuel burning or use in industrial settings. Hence, the present invention introduces a technique for generating and storing the potential energy by using an elastic member.

[0005] Furthermore, due to increasing pollution and smoke on the earth, we need a system that causes less damage to the environment. That is why the technology used in the present invention is implemented. The system can be charged in several ways. For example, by rivers flowing water, by ocean waves, or by the movement of animals like horses, elephants can regenerate the system by human power hence reducing the pollution in the environment.

[0006] The elastic or spring energy is the potential mechanical energy stored in the configuration of a material or physical system as work is performed to distort its volume or shape. The elastic potential energy equation is used in calculations of positions of mechanical equilibrium. The energy is potential as it will be converted into another form of energy, such as kinetic energy. The continuous vibrations or movement of the elastic members such as spring or rubber results in the conversion of energy i.e. potential energy to kinetic energy. During the process, a certain amount of energy is released as a part of the work done which is harnessed as a power source.

[0007] The system may be used in goods and public transport. All ships running on water will run on the proposed system. The ship's system will be charged by the hull of the seawater. The same could apply to ships on land and water. The system may also generate electricity, and may also charge the electricity system. One of the features of the proposed system is nothing fires anywhere in the system.

[0008] There is a lot of energy in different forms, but it is difficult to store the energy and use that energy at the time when it is needed. At critical times there is an inverter battery that stores electric energy. Then we can use the energy according to our needs. However, it takes a long time to charge. Today people need a system that can be charged in multiple ways and recharge in a short duration of time so that we can use energy according to our requirements. Also, in recent times, secondary batteries like lithium-ion batteries, which are exemplary energy storage devices known for their impressive energy density, have gained significant prominence. They are now crucial components in a variety of applications, serving as essential energy storage solutions.

[0009] Further, there is a growing need for reliable and efficient energy storage solutions. Traditional methods for storing energy, such as batteries, can be bulky, expensive, and have limited lifespans. Renewable energy sources, such as solar and wind power, are becoming increasingly popular, but they often require energy storage solutions to address their intermittent nature.

[0010] A prior-art reference “IN’ 202,447,013,066” titled “Electric power storage module” provides a system that discloses an electric power storage module comprises an electric power storage device and a holder holding the electric power storage device. The electric power storage device comprises- a plurality of cylindrical electrodes; a plurality of containers individually containing the plurality of electrodes; and a film exterior having a sealing part sealing each container and interconnecting the plurality of containers. The holder is adhered to the sealing part. The holder has a plate shape extending in the first direction,comprises a plurality of recesses of trapezoidal prism shape that are arranged in the first direction and into which housing parts are respectively fitted, and also comprises a plurality of flat parts that connect the recesses adjacent to each other and that are bonded to a sealing part, and wherein the electricity storage module has a honeycomb structure in which a plurality of hexagonal prism-shaped spaces respectively surrounding the housing parts are arranged.

[0011] Whereas, the present invention provides an energy storage system and a portable device to store the energy using the elastic members. The system comprises a housing, a plurality of holders coupled to the housing, a movable shaft, and an input energy source to apply the force on the plurality of elastic members. The input energy source applies the force such that it compresses the elastic members, thereby storing energy in their compressed or twisted state. The stored energy can then be released through the opening of one or more locks and used for one or more end applications, such as power source, power buffer, recoil mechanism, kinetic energy application, or any other application capable of using the potential energy.

[0012] Another prior art reference “5680 / CHE / 2013” titled “Spring based electrical power generator" provides a similar system to generate power through a spring assembly wherein the system converts vibrational energy into electrical energy. The system comprises a self-starter, a flywheel, an alternator, an electrical motor, a spring assembly, an oil mechanism, a primary transmission gear, a secondary transmission gear, a power supply, a control panel, and a base frame. The oil assembly comprises an oil sump to store lubricating oil for input and output spring assembly and rotating parts. Further, the oil assembly includes an oil pipe to act as an inlet for fresh oil into the oil sump and the oil drain acts as an output for used oil from the oil sump.

[0013] Whereas, the present invention provides an energy storage system and a portable device to store the energy using the elastic members. The system comprises a housing, a plurality of holders coupled to the housing, a movable shaft, and an input energy source to apply the force on the plurality of elastic members. The input energy source applies the force such that it compresses the elastic members, thereby storing energy in their compressed or twisted state. The stored energy can then be released through the opening of one or more locks and used for one or more end applications, such as power source, power buffer, recoil mechanism, kinetic energy application, or any other application capable of using the potential energy.

[0014] In view of the above prior arts, there is a need for an energy storage system based on elastic members with a long-time running mechanism to produce large amounts of electrical energy continuously. Thus, there exists a dire need in the art, to provide a system and device for storing the potential energy using the elastic member and use the energy as and when required.OBJECTS OF INVENTION

[0036] Hereinafter, exemplary embodiments of the present disclosure will be described with reference to the accompanying drawings.

[0037] FIG. 1 illustrates the block diagram of the energy storage system (100) (hereinafter ‘system’) that uses an elastic member to store the energy, in accordance with an exemplary embodiment of the present disclosure.

[0038] The present disclosure describes an energy storage system (100) utilizing a plurality of elastic members (101) for efficient storage of potential energy. The system (100) offers a reliable and versatile solution for capturing and storing energy from various sources.

[0039] Referring to FIG. 1, the energy storage system (100) comprises the following key components housed within a housing (102).• Housing (102): The housing (102) is used to protect the internal components of the system (100). It can be manufactured from a rigid material such as metal or high- strength plastic, ensuring structural integrity and secure containment of the elastic members (101).• Elastic Members (101): The multiple, individual elastic members (101) capable of storing potential energy when compressed or twisted. Examples of suitable elastic members (101) include springs, rubber bands, or compressed gas canisters. The specific type of elastic member chosen will depend on factors like desired energy storage capacity and force requirements.• Holders (102-1, 102-2): At least two holders (102-1, 102-2) are positioned within the housing (102). Each holder has a first side and a second side. The holders (102-1, 102-2) serve as fastening points for the elastic members (101). each elastic member (101) is directly connected between the first sides of both holders (102-1, 102-2). The first sides in this context refer to the inner faces of the holders (102-1, 102-2) positioned towards each other within the housing (102).• Movable Shaft (103): Each elastic member (101) is positioned around a corresponding movable shaft (103) The endpoints of each elastic member are then connected to the respective movable shafts (103). Furthermore, the movable shafts (103) themselves are connected between the first and second holders (102-1, 102-2). The rotational force applied to the movable shafts (103) compresses the elastic members (101) and stores potential energy.• Movable Connectors (106): The movable connectors (106) for connecting each elastic member (101) to both holders (102-1, 102-2). The movable connectors (106) are designed to move or rotate, applying force on the associated elastic member to compress ortwistthe elastic members (101), and store potential energy.• Control unit (109): The system (100) includes the control unit (109) comprising one or more microcontrollers or one or more actuators. The control unit (109) is used to control and perform one or more operations in the system. The control unit (109)manages the operation of the system. The control unit (109) is coupled to the housing (102).

[0040] In an embodiment, the energy storage system (100) utilizes a gear arrangement (104) as the input energy source (105) housed within the first holder (102-1). The gear arrangement (104) is operatively connected to a movable shaft (103) also located within the first holder. Each elastic member (101) is then connected to the movable shaft (103). When one or more gears in the gear arrangement (104) rotate, it transmits force through the movable shaft (103), compressing or twisting the connected elastic members (101).

[0041] The energy storage system (100) revolves around compressing or twisting the elastic members (101) to store potential energy. Regardless of the specific embodiment used for connection, an input energy source (105) applies force to the elastic members (101) through the first holder (102-1) or other components gear arrangement (104), movable connectors (106), or movable shafts (103). The compression of the elastic member converts the input energy into potential energy stored within the compressed or twisted state of the elastic members.

[0042] In another embodiment, the specific design and configuration of the system (100) will determine the type of input energy source (105) (e.g., electric motor, human crank) and the means of applying force for compression (e.g., gear rotation, connector movement, shaft rotation).

[0043] In a nutshell, the energy storage system (100) offers a versatile and efficient solution for capturing and storing energy using elastic members. The various embodiments for connecting the elastic members provide flexibility in design and functionality and allow to adapt to different application requirements.

[0044] In these embodiments, the system (100) includes the plurality of the elastic members (101) which are selected from a group of springs, cantilever beams, rubber bands, compressed gas springs, leaf springs, or any other elastic member capable of storing the energy. The system (100) may use the below material as the elastic member.• Springs (e.g., coil springs, helical springs, leaf springs) - Springs are the most common type of elastic member used for energy storage due to their high energy density and well-defined compression characteristics.• Cantilever beams - Cantilever beams may be used as the elastic member which are beams fixed at one end and free at the other. When a force is applied to the free end, the beam bends, storing elastic energy.• Rubber bands - Rubber bands are simple and inexpensive elastic members (101), but they may have lower energy density and fatigue over time compared to other options.• Compressed gas springs - The compressed gas springs use compressed gas to provide a restoring force. They can offer high energy density but require careful design and safety considerations.The selection of the specific type of elastic member in the system (100) may depend on factors such as the desired energy storage capacity, weight limitations, and cost considerations.

[0047] In an embodiment, the system (100) includes one or more locks (107-2) connected to the second holder (102-2) and coupled to each of the plurality of elastic members (101), such that opening of the lock enables the release of the at least one compressed or twisted elastic member to reach to an uncompressed or untwisted position and to thereby release the stored energy while the at least one compressed or twisted elastic member reaches to the uncompressed or untwisted position.

[0048] In an embodiment, the first and second end of each of the holders (102-1, 102-2) enclosed inside the housing (102) can be integrable based on the requirements of the user and the type of application for which the system (100) is used.

[0049] In an embodiment, the plurality of the elastic members (101) is compressed or twisted in an inward direction or an outward direction based on the selected direction by a user to compress or twist the plurality of the elastic members (101).

[0051] In another embodiment, the present invention includes the round circle spring device, wherein the spring is used as the elastic member. In the round circle, there may be multiple elastic members (101) on top of others, which gives the output energy in the form of power to use in one or more end applications.

[0052] In an embodiment, the system (100) may be in the form of a mechanical device that can be used to store the power. Further, the system (100) can be a standalone device or integrated into a larger system. The primary function of the system (100) is to accumulate and store energy for later use in one or more end applications.

Similar to wind turbines, the rotational force is harnessed to compress or twist the energy storage elements. iii. Ocean wave energy: Wave energy converters can capture the kinetic energy of waves and convert it into rotational motion. The rotation can then be used to compress or twist the system's energy storage elements. iv. Non-renewable energy sources: The system can be charged from the existing electrical grid using a suitable charging mechanism that converts AC grid power into a form compatible with the energy storage elements (e.g., DC for batteries).

[0054] In an embodiment, one or more end applications in which system (100) may use is selected from a group of power sources, power buffers, recoil mechanism, kinetic energy application, or any other application capable of using the stored potential energy.
