REPLACEMENT

1. Domain of technology considering this invention

This invention refers to technical solutions regarding battery and battery powered device (mainly cellular phones and smartphones) where battery powered device remains constantly powered during battery replacement.

Field of technology directly affected by here stated invention is classified in the International Patent Classification (IPC) as: H02J, H04B, H04M.

2. Technical problem

Technical problem solved by this invention is power discontinuity which occurs while replacing empty battery with fully charged one causing cessation of any activity performed by the device user regardless of how short mentioned period lasts.

Necessity for this solution is increased by the fact that there is considerable amount of time needed for an operating system of smartphone to boot after battery replacement, even if period of battery change is rather contracted. Furthermore, after booting operating system user is delayed even more because of additional time required for previously used programs to load. Only after all that time spent on battery replacement and booting up operating system and desired programs, one can continue using the device.

Technical problem is related to all devices which continue to operate even if not connected to the stable power source (i.e. wall socket) and have batteries to provide power autonomy and system stability.

Period of power autonomy is determined by the battery capacity which is limited (usually to a few hours) and after expiration of that time it is necessary to either connect the device to an external power source to recharge battery or replace the drained battery with new/charged one.

This is current state with cellular phones, smartphones, laptop computers, tablet computers etc. Cellular phones, especially smartphones and tablet computers, have numerous comprehensive functions and stronger processors in combination with more demanding software applications that negatively affect power autonomy and cause problems like fast battery exhaustion, i.e. short battery operating time.

Because of already stated problems this type of device must be connected to a charger after shorter and shorter operational periods. Connected to an external charger, mobile devices become impractical to use and wired thus becoming opposite of intentioned - immobile.

Batteries can be replaced but that is rather demanding task for an average user because it lasts considerably long and there are even devices where battery replacement is not possible at all because it is permanently closed in the housing of the device.

Battery replacement usually implies certain procedure that consists of removing back lid of the device creating space for removing battery from the battery compartment, removing battery from its compartment and fitting new or full battery in place of an empty one, and finalizing the procedure with closing back lid of the device.

3. Known state of the art

As known, cellular phones, smartphones, laptop and tablet computers need electricity ensured by the batteries nowadays offered in many types and designs and every one of them has certain capacity valued by the unit mAh. When the battery powered device is operational, it drains the battery, i.e. lowers its capacity where one must be careful not to reach lower threshold of battery capacity under which the usage of battery is not recommended and the battery must be recharged to its full capacity or replaced with new or recharged battery. Usually, the battery which capacity reached lower threshold of capacity is called "empty" battery even though it is technically not fully emptied since it has some amount of electricity to run the complementary device for some short period of time, while brand new or fully charged battery is called "full" battery. In accordance with previously stated, in further text term empty battery implies a battery which capacity is lowered to the lower recommended threshold of capacity, meaning it is not yet fully emptied since it can still provide the power for the complementary device, but not for long period of time; and term full battery is used for fully charged or brand new battery.

According to the currently known state of the art, both cellular phones and smartphone devices are equipped with batteries which capacity is sufficient for supplying electricity for the device during work hours keeping in mind recharging batteries during night and restoring their full capacities by the next morning.

If lower recommended threshold of capacity is reached before ending of planned working day and there is still need for smartphone use, one must either plug the device to the charger when device becomes immobile or replace the empty battery with recharged one. Charging battery while using the device has numerous disadvantages thus replacing battery makes more logical and convenient choice.

According to the currently known state of the art, in most cellular phones and smartphone devices batteries (1.1 ) are placed in the housing (1.5) of the device which has removable lid on the back side that has to be removed to access the battery (1.1 ) inserted in the battery compartment (1.2) inside the device.

Prior to battery removal, device must be turned off, stopping any kind of work done on device, and the device remains completely without power during battery replacement. Battery occupies a position (2.1 ) both during removal from and inserting into battery compartment (1.2) and moves in one of two possible directions (2.2) depending on weather it is being inserted or removed from the battery compartment (1.2).

When battery is finally inside the device, lateral side (1.6) of the battery, in which the contact pins (1.3) are located, is facing lateral side (1.7) of the battery compartment inside the device on which are located contact pins (1.4) in the device housing; all in such manner that contacts (1.3) on the battery align and connect with the contact pins (1.4) in the housing of the device which creates an electrical connection of pins (1.3) on the battery with pins (1.4) on the housing of the device meaning battery (1.1 ) supplies electricity to the belonging built-in components inside of the housing (1.5).

When battery (1.1 ) is removed from the housing (1.5) of device, contact pins ( .3) on the battery and contact pins (1.4) in the housing are separated thus electrical circuit is broken and power supply of the device is discontinued. When battery (1.1) is inserted in the battery compartment (1.2) in the device, contact pins (1.3) on battery and contact pins (1.4) on device housing are connected and the electrical circuit is active, feeding the device with electricity from the recharged/new battery. After battery replacement is done, device must be turned on and one must wait for the operating system to boot so one could resume ones work which had been stopped previously to battery replacement.

All of the solutions known according to the current state of the art, are experiencing power supply discontinuation during battery replacement causing already stated disadvantages and unwanted consequences. Some solutions reduce amount of time required for the battery replacement and so the time of energy supply interruption.

Technical solution according to the patent specification US2006/0226804 provided solution where battery has slide channels on two lateral narrow sides and in the housing of device there are compatible sliders which substantially shortens battery replacement time.

On the other hand, in the patent specification US2003/0003949 was specified solution with certain hooks on the housing of device which hold battery mechanically attached to the housing providing shorter battery change interval thanks to the technical solution where in place of lid and screws, hooks make significant time spare both in terms of attaching and detaching battery.

4. Core of the invention

Idea of technical solution according to invention is consisted of battery and housing connection pins located and engineered in such a manner that procedure of replacing empty battery with full one is possible without breaking the electrical circuit thus power supply is constant during all stages of battery replacement. Battery compartment (1.2) inside the device is made completely open on both sides of the housing (1 .5) forming complete gap (3.6) throughout whole housing of device.

Battery contact pins, according to the current state of the art are located on the slimmer lateral (1.6) side of the battery ( .1 ), and are now, according to innovation, located on one of two wider sides (3.3) of the battery while housing contact pins according to the current state of the art are located on the narrow lateral side of the device battery compartment (1 .7), and are now, according to innovation, located at the bottom (1.2) of the battery compartment inside housing of device.

Contact pins on both battery (1 .1 ) and inside housing (1.5) can be engineered in two following ways:

Ad 1 ) Battery contact pins are engineered as slide (3.2) contact pins shaped as strips, and housing contact pins in that case are dotted (3.7) contact pins.

Ad 2) Battery contact pins are engineered as dotted (6.1 ) contact pins, and housing contact pins in that case are engineered as slide (6.2) contact pins shaped as strips.

Dotted (3.7) and (6. ) contacts, circular or square shaped, have diameter (or side length in case of square shaped dotted contacts) of matching size with slide (3.2 and 6.2) contact pins/strips width, or can be different in matching ratio of 1 :1 with appropriate slide (3.2) and (6.2) contact pins/strips width.

For continuous power support during battery replacement to be achieved, distance (R _t ) between dotted contact pins both in the housing (3.7) and on the battery (6.1 ) must be coordinated with distance (L _k ) between slide contact pins/strips both on the battery (3.2) and in the housing (6.2) of the device in such a manner that, during battery replacement in which full battery pushes empty battery towards the other side of the gap (3.6) through housing, contacts on the full battery are connected to the contacts in the housing of the device while contacts of the empty battery are still connected to the contacts in the housing creating simultaneous powering of device by both of the batteries in parallel connection and that state lasts for certain time after which empty battery, pushed out by the full battery, is disconnected from the housing contact pins. After that, device is powered only by the full battery inserted and fixed in its final position inside of the housing of device.

According to the invention, battery is inserted in the gap area (3.6) trough device housing, in such way that its side (3.3), which has slide (3.2) or dotted (6.1) contact pins, is facing lower side of the area for battery installation (1.2) inside of the device. Lower side of the area for battery installation has dotted (3.7) or slide (6.2) contact pins, thanks to which connection is established between dotted and slide contacts on the battery and on the housing, and powering the device is achieved directly from the battery. Battery itself is in the middle of the area (1.2) in the battery compartment inside of the device and fixed with elastic holders, which can be engineered in a way that elastic pin (3.9) of the elastic holder, inside of the device, enters the dent (3.8) on the battery.

Elastic holders of the battery consist of pin (7.2) with a spherical top which is located with a spring (7.3) inside of the housing (7.1). Spherical top (7.2) pushed by the spring (7.3) enters the dent (3.8) on the battery and keeps it firmly in place.

It is recommended to achieve that lateral sides of the battery, fixed in described way, align with housing and in that case there is no need for extra closing lids on the sides of the battery compartment gap (3.6) through the housing which adds extra space for other components of the device.

Act of switching batteries of the device without interrupting power supply is extremely simple, easy and fast by switching two identical batteries of which one is empty and the other one full. Full battery needs to be aligned in the same position as the empty one inside the device, parallel with it, and with its side wall leaning on the side wall of an empty battery pushing it with certain force throughout the gap (3.6), and during that procedure elastic pin (3.9) in the housing derails from its pin holder dent (3.8) on the battery allowing exit of the empty battery on the other side of the battery gap (3.6) while contact dotted pins slide on slide contact pins/strips meaning that power supply remains constant and still supplied from the empty battery until contacts of the full battery (slide 3.2 or dotted 6.1) are connected to the contacts in the housing of the device (dotted 3.7 or slide 6.2) when power is supplied by both of the batteries in parallel connection. After that, empty battery is pushed out the other side of the battery gap (3.6) causing disconnection of that battery from parallel circuit leaving only full battery connected to the contact pins which means that from that moment full battery powers the device by itself and slides behind empty battery until elastic pin (3.9) on the housing enters the pin dent (3.8) on the full battery and fixes it in place while empty battery falls out from battery gap (3.6) leaving full battery to power the device permanently until exhausted and the procedure is repeated.

Replacing the battery and placing it in the right position can be sped up by designing a battery in such way that it has slide runner (3.4) while battery gap (3.6) in the housing is designed with slide channel (3.10).

Described battery replacement procedure causes no power supply interruption. In the very beginning of the procedure, device is powered exclusively by the empty battery, and after that the device is powered by both empty and full battery at the same time in parallel connection. At the very end of the battery replacement procedure, full battery takes over the supplying of the device with power while empty battery is removed from the device.

The result of this technical continuous power supply solution is that device does not require shutting down and/or rebooting operating system. Empty battery is replaced with full one which, according to invention, lasts maximum of several seconds.

This procedure makes the device more convenient and practical to use because it is never connected to charger with a cord. Current state of technology is that mobile devices are connected with a cord to charger for a period of even several hours making that same mobile devices immobile. Furthermore, period of active usage of the device is drastically extended because empty battery is simply replaced by the full one and the device remains running and mobile for even numerous number of battery replacements. This invention can be used on all modern mobile devices. 5. Short explanation of drawing/scheme
