Description
- The present disclosure is related to an automated machine that is able to paint a human nail.
- The desire to paint one's nails has been popular for centuries, dating back to 3000 B.C. After the tech boom of the 1980's, the integration of electronics as a matter of convenience and efficiency became increasingly popular, including machines that are capable of performing nail art. In 1999, Japanese company Atlus launched a nail art machine labeled “NailMore.” Subsequently, other companies launched similar nail art printing machines, for example, Plenty Inc. launched their “Nail Art Club Machine” in 2003, and Mattel launched their “Barbie Dolled Up Nail Printer” in 2009. Each one of the above mentioned machines uses a method of printing an inkjet pattern on a human nail that has been previously treated with an ink receptive nail polish. The major drawbacks for these machines it that they can be complicated, expensive, time consuming, and bulky.
- The present inventor has recognized is that it is desirable to provide a machine that is less expensive, less time consuming, compact, and further has the capability to treat the nail with nail polish rather than have the user paint the nail prior to using the device. Additionally, the inventor has recognized the need for the device to receive consumable cartridges that can contain various types and colors of nail painting liquid.

-
FIG. 1 shows an isometric view of an exemplarynail painting machine 1. Thenail painting machine 1 has abase 10. The base may include a run-offchannel 12 and ahand receiving portion 14. As can be seen inFIG. 1 , thehand receiving portion 14 may be a protuberance, having a bulbous shape. However, thehand receiving portion 14 of thenail painting machine 1 is not limited to a bulbous shape, and may be any other suitable shape. Thehand receiving portion 14 may define at least onefinger receiving area 14 a. - As shown in
FIG. 1 , thehand receiving portion 14 may define a plurality of circular shaped depressions, which is thefinger receiving area 14 a. However, it is contemplated that thefinger receiving area 14 a may be a channel or any other suitable shape. Thehand receiving portion 14 may be composed of a durable and non-slip surface, for example, rubber. The surface may be textured. The base 10 may be composed of one type of material or may be composed of different materials. For example, thehand receiving portion 14 may be a rubber sheet, the run-off channel 12 may be a metal plate, and the remainder of the base 10 may be a polymer. - The
nail painting machine 1 further includes acasing 20, which may include at least onesensor 30, anindicator 22, and alever 24. The at least onesensor 30, which may be a camera, may be positioned facing thehand receiving portion 14 such that it can adequately sense the position and dimensions on the finger nails of the user. For example, thesensor 30 may be positioned in front of the hand and adapted to detect the thickness and the curvature of the finger, or thesensor 30 may be positioned over the hand and is adapted to detect the boundaries of the nail. It is also envisioned that thenail painting machine 1 may further include a second sensor (not shown). For example, thefirst sensor 30 may be positioned in front of the hand and adapted to detect the thickness and the curvature of the finger and the second sensor may be positioned over the hand and is adapted to detect the boundaries of the nail. However, these are merely examples and the at least one sensor can be located in any suitable place on thenail painting machine 1. - The
indicator 22 may be disposed in a cut-out in thecasing 20. Theindicator 22 may be an LED and is configured to indicate to a user of thenail painting machine 1 what actions to take. For example, if the indicator shows a green light, it is ready to commence or has finished operation. When the indicator shows a red light, there is an error in the system. - The
casing 20 may be hollow and may contain acartridge receiving portion 300 and aposition assembly 400 therein (shown inFIG. 5 ). In operation, thelever 24 may be locked when in a flat or first position. The lever may form alip 25 that is at the distal end thereof. Thelip 25 may be disposed such that when the lever is in the first position, thelip 25 is easily accessible to a user of thenail painting machine 1. Additionally, when the lever is in an upright, or second position, thecasing 20 may be opened, exposing thecartridge receiving portion 300. In this second position, a user of thenail painting machine 1 is able to insert acartridge cartridge receiving portion 300. - The
base 10 andcasing 20 may be a monolithic structure, however it is also contemplated that the base 10 may be removably attached to thecasing 20. - Turning to
FIGS. 2A and 2B which show anexemplary cartridge 100. Thecartridge 100 may include acontainer 110 which has an openfirst end 112 and an opensecond end 116. The cartridge may be substantially cylindrical in shape, however, it is also contemplated that the cartridge can be another other suitable shape, for example, a pyramid. In this embodiment, thecartridge 100 may further include aplunger 130, theplunger 130 having agasket 132 circumscribing the outer surface thereof. Theplunger 130 may be adapted to slide from a first position near thesecond end 116 of thecontainer 110 to a second position near thefirst end 112 of thecontainer 110. - Additionally, the
cartridge 100 may include anapplicator 120 liquidtightly connected to afirst end 112 of thecontainer 110. Theapplicator 120 may have adischarge vent 122, amount 124, and apad 125. It is contemplated that the pad may be a brush or a fin or any other suitable means for applying the contents of thecartridge 100. - The
container 110 of thecartridge 100 may be hollow and may be adapted to contain a nail polishing liquid therein. The liquid may be any one of a suitable nail polishing liquid, including but not limited to, shellac, gel, or varnish. - The
gasket 132 of theplunger 130 may be adapted to sealingly engage the inner surface of thecontainer 110 of thecartridge 100. Thegasket 132 of the plunger may be composed of rubber, or any other suitable material. - In operation, when the
plunger 130 is moved from the first position to the second position, pressure is applied to any contents within thecontainer 110. The contents are then expelled out of thedischarge vent 122 and onto thepad 125 of the applicator. The discharge vent may be formed as an elongated cylindrical body that has an opening on each end. One end of the opening may be adapted to be in communication with any contents that are within thecontainer 110. The other opening may be biased to face thepad 125 such that any contents that are expelled from thecontainer 110 are directed toward thepad 125. -
FIG. 2B is a variation of the exemplary cartridge inFIG. 2A . The cartridge may have adischarge vent 126 that extends along the width of thepad 125. Thedischarge vent 126 may be formed to have an elongated opening that corresponds with the width of thepad 125 such that the contents that are expelled out of the discharge vent uniformly coats the entire width of thepad 125. - Turning to
FIGS. 3A and 3B , anotherexemplary cartridge 200 is shown.Cartridge 200 may include acontainer 210 having afirst end 212 and asecond end 214. The container may further include achannel 220 extending between the first and second ends 212, 214 andform openings channel 220 may be partially a solid continuous piece and the remainder is agrate portion 222, which definesholes 224.FIG. 3A shows thegrate portion 222 having a plurality of holes, however it is contemplated that thegrate portion 222 may have any number of holes therein. -
Container 200 may be a first, retracted position, wherein aplunger 230,spring 232, andapplicator 226 may be inside of and disposed withinchannel 220. Theplunger 230 may be sealingly engaged with thegrate portion 222 of thechannel 220 such that any liquid inside of the container is not expelled out of theopening 216. Positioned between thegrate portion 222 and theplunger 230 is thespring 232. When thespring 232 is in an uncompressed position, theplunger 230 andapplicator 226 may be retracted into thechannel 220 of thecontainer 210. Theapplicator 226 may be affixed to the end of the shaft of theplunger 230 b, on the opposite end of the head of theplunger 230 a. While in the retracted position, theapplicator 226 may be sealingly engaged withholes 224 such that the contents of thecontainer 210 do not fluidly communicate withopening 218. Thus, in operation, for example, theapplicator 226 obtains nail polish when thecartridge 200 is in the retracted position or the spring is in an uncompressed state. In the configuration inFIG. 3A , opening 218 may be obstructed by a seal or removable plug. -
FIG. 3B shows thecartridge 200 in a second, extended position. In this position, theplunger 230 is also in a second position wherespring 232 is in a compressed state. Specifically, the shaft of theplunger 230 b may be partially extending away from and out of opening 218 such that theapplicator 226 is on the exterior of thecontainer 210. - The terms uncompressed and compressed should not be restricted to meaning a fully uncompressed state or a fully compressed state. The term uncompressed means that the spring is in a more expanded state than when the spring in the compressed state. This also applies to the term compressed state.
- In operation, the
cartridge 200 may start in a retracted and sealed state. Once theplunger 230 is engaged, which may be performed by accessing the head of theplunger 230 a viaopening 216, and is moved from a first position, where thespring 232 is uncompressed, to a second position where the spring is compressed, a seal onopening 218 is ruptured and theapplicator 226 and shaft of theplunger 230 b are permitted to pass though opening 218 and extend out of and away fromcontainer 210. In this second position, any contents inside of thecontainer 210 are not able to pass throughholes 224 of thegrate 222 and be expelled from opening 218. If it is desired to apply contents onto theapplicator 226, thecartridge 200 may be returned to the retracted position. - However, it is envisioned as an alternative example that the contents inside of the container may be able to pass through
holes 224 of thegrate 222 when thecartridge 200 is in the extended position. In this configuration, the contents inside of the container can flow along theapplicator 226. In both of the aforementioned examples, it is envisioned that the contents inside of thecontainer 210 may be a nail polish liquid. -
FIG. 4 showscartridge 100 secured within thecartridge receiving portion 300 of thenail polish machine 1. Here, the receiving portion may include acollar 310 having afirst end 312 and asecond end 314. Thecollar 310 may be cylindrical in shape, however any other suitable shape may be used. Housed withincollar 310 may be aspring 330 and agrip ring 332. Thegrip ring 332 may have a plurality offlexible fingers 334, each of theflexible fingers 334 may define alip 334 a andflange 334 b. Thecollar 310 may additionally have a plurality ofwindows 336. Thewindows 336 may be positioned in a manner to correspond with the location of thefingers 334, for example, thewindows 336 may be equally spaced in three locations about the circumference of thecollar 310. - In operation, then the receiving portion is in a first state, where
spring 330 is uncompressed, thecartridge 100 may be inserted or captured into theflexible fingers 334 of thegrip ring 332. Thereafter, the receivingportion 300 may be transitioned into a second state, wherespring 330 is compressed and theflanges 334 b of thefingers 334 snap intowindows 336 of thecollar 310, thereby fixing thecartridge 100 into the receivingportion 300. To release thecartridge 100 from the receivingportion 300, theflanges 334 b may be lifted and pressed throughwindows 336, such that thefingers 334 are capable of sliding within thecollar 310. -
FIG. 5 shows thepositioning assembly 400 of thenail painting machine 1. This positioning assembly may be housed within thecasing 20 of thenail painting machine 1. Additionally, the positioning assembly may be adapted in a manner such that the applicator of the cartridge can extend out of thecasing 20 and maneuver between thecasing 20 andbase 10. - The
positioning apparatus 400 may include afirst motor 412 affixed to afirst rack 410, the first rack being slideably attached to afirst guide 414 allowing thepositioning apparatus 400 to move in a first direction along a first axis; asecond motor 422 affixed to asecond rack 420, thesecond rack 420 being slideably attached to asecond guide 424 allowing thepositioning apparatus 400 to move in a second direction along a second axis; and athird motor 432 affixed to athird rack 430, thethird rack 430 being slideably attached to athird guide 434 allowing thepositioning apparatus 400 to move in an third direction along a third axis. The positioning assembly may further include afourth rack 440 that includes thecartridge receiving portion 300 as well as afourth motor 442, a cartridge actuator means 500, and an electronic control unit (ECU). Theracks third motors - The
fourth motor 442 is configured to allow thecartridge receiving portion 300 to rotate about at least one of a first, second or third axis. - The cartridge actuator means 500 may be any suitable means to engage the
plunger cartridge FIGS. 7 and 8 . - The ECU may have a preloaded program that executes commands to the
motors indicator 22. Each of the motors may be capable of being controlled by a GRBL controller or any equivalent control means. - Generally, the program that is loaded onto the ECU is programmed to detect if a cartridge has been loaded into the
nail painting machine 1, detect if an object has been placed in thehand receiving portion 14, and then execute a nail painting program. This detection is made by at least one sensor, which may be a camera. - The ECU can be adapted to execute a program that may detect an area of the nail. This detected area can be transformed into an ellipse to compare geometric data (for example, half-major axis, half-minor axis, foci, etc.) between different detections. Further, the characteristic points of the nail or detected zone are also acquired. Next, the program compares the orientation of the semi-major axis of the ellipse with the detected axis of the finger. Preferably, the width of the major axis of the ellipse is not greater than the width of the nail considered. The lowest point can be on the finger nail axis. The lowest point may be the most proximal portion of the nail. Performing this comparison makes it possible to reject errors.
- Further, the program may refer to a library of stored previous detections. This library may be “clustered” in a manner such that the types of detected nails are grouped together according to the geometrical data and the results of previous painting operations. The program uses a statistical distribution of the acquired geometrical data of the nails to determine how the data should be clustered. This clustering process is used primarily to determine whether the detected area is a nail, but it can also be used to assign specific painting method to a type of nail shape.
- In operation, if the ECU determines that an error has occurred and rejects the detection, the input of the detection is changed and the output (for example, the detected area) is then used in the program. This process may be repeated until the output is accepted (for example, placed in the right cluster).
- Once a nail is positively detected, a matrix of pixels is populated assigning a value of “1” if the pixel is associated with the edge of the nail and “0” otherwise. A conversion from pixels to millimeters is made using the matrix. This conversion of pixels to millimeters, or map, is preloaded in the program. Then a coordinate system is determined from the pixels to millimeter coordinates.
- The program then calculates the trajectory of the
cartridge positioning system 400 to lower thecartridge cartridge - Specifically, the positioning assembly should be compact in order to move properly within the
casing 200 of thenail painting machine 1. For example, thefirst rack 410 may be adapted to translate 50 mm on the first axis, the second rack may be adapted to translate 50 mm on the second axis, and thethird rack 430 may be adapted to translate 30 mm on the third axis. Additionally, it is preferable to rotate theapplicator 25 to 50 degrees relative to the nail. - Turning to
FIGS. 7 and 8 which show a cross section of the cartridge actuation means 500. InFIG. 7 , the cartridge actuation means 500 is in a first retracted position and inFIG. 8 , the cartridge actuation means 500 is in a second, extended position. Here, the actuation means is a linear actuator that has a 20 mm course. However, it is contemplated that any other means of transitioning theplunger cartridge - In operation, once the nail polishing program has positioned the
cartridge plunger cartridge - Throughout the description, including the claims, the term “comprising a” should be understood as being synonymous with “comprising at least one” unless otherwise stated. In addition, any range set forth in the description, including the claims should be understood as including its end value(s) unless otherwise stated. Specific values for described elements should be understood to be within accepted manufacturing or industry tolerances known to one of skill in the art, and any use of the terms “substantially” and/or “approximately” and/or “generally” should be understood to mean falling within such accepted tolerances.
- Although the present disclosure herein has been described with reference to particular embodiments, it is to be understood that these embodiments are merely illustrative of the principles and applications of the present disclosure.
- It is intended that the specification and examples be considered as exemplary only, with a true scope of the disclosure being indicated by the following claims.
