[0018] The disclosure relates to a cosmetic deposition device 100 used to print cosmetic styles onto a surface, such as the skin or face. As shown in FIGURES 1 and 2, the cosmetic deposition device 100 includes a handle 135, a housing 102 connected to the handle 135, which can be connected at right angles to the handle 135. In one embodiment, the housing 102 is a cylindrical-shaped housing having a display 140 at one end of the housing and an applicator face 104 at the opposite end of the display 140.

[0019] The display 140 of the cosmetic deposition device 100 may represent a user interface for a subject to control operations, features, and options of the cosmetic deposition device 100.

[0020] Referring to [Fig. 2], the applicator face 104 is part of a cosmetic deposition assembly 110 that also includes a print head 145. The applicator face 104 includes an elongated roller 115 that is positioned between two spacers 114A and 114B. The spacers 114A, 114B and the roller 115 extend under a flat surface of the applicator face 104 to keep the underside of the device separate from the surface.

[0021] The printhead 145 is visible through an opening in the applicator face 104. In particular, the rows 106A, 106B, 106C of nozzles of the printhead 145 are visible through the opening in the applicator face 104. The opening in the applicator face 104 allows the rows 106A, 106B, 106C of nozzles to deposit the formulation through the opening.

[0022] Referring to FIGURES 4A and 4B, the cosmetic deposition assembly 110 includes the applicator face 110 and the print head 145. The print head 145 includes a printing technology and formulation cartridges 119A, 119B and 119C. In one embodiment, the printing technology employed is generally referred to as “inkjet” printing. For example, US 2020 / 0171831 to Prinker Korea Inc. discloses a printing technology.

[0023] In one embodiment, the printhead 145 includes three rows 106A, 106B, and 106C of nozzles ([Fig. 3]). Each row 106A, 106B, and 106C may include up to hundreds of nozzles that may be expressed in "dots per inch" (dpi), for example, 150 dpi, 300 dpi, and 600 dpi. A piezoelectric element is paired with each nozzle, and each of the piezoelectric elements is controlled by one or more processors 120. In one embodiment, each row of nozzles 106A, 106B, and 106C is configured to dispense a single formulation from the corresponding cartridge 119A, 119B, and 119C.

[0024] One side of the applicator face 104 is on the outside and on one end of the housing 102 and a second, opposite side of the applicator face 104 is attached to the underside of the housing 102. When the cosmetic dispensing device 100 is in use, the applicator face 104 maintains contact with a surface via the roller 115 to ensure proper spacing from the surface and smooth translation across the surface. The applicator face 104 includes an opening allowing the nozzle rows 106A, 106B, and 106C to dispense the formulation onto the surface. To avoid smearing, it is desirable that the device 100 be moved in a direction such that the roller 115 follows behind the nozzle rows 106A, 106B, and 106C.

[0025] In one embodiment, the applicator face 104 includes a mechanism for rotating the applicator face 104, independent of the entire device 100. This allows makeup to be applied in any direction without changing the orientation of the entire device 100.

[0026] As illustrated in FIGURES 4B and 5B, the lower side of the housing 102 includes a flat annular disc 112 at the inner periphery of the housing 102. The flat annular disc 112 includes a circular opening for the printhead 145. In one embodiment, the printhead 145 may be attached to the applicator face 104 and rotate in conjunction with the applicator face 104. In a embodiment, the print head 145 does not rotate with the applicator face 104.

[0027] The flat annular disc 112 includes one or more pawls 160 that support the applicator face 104 while allowing rotation of the applicator face 104 relative to the housing 102.

[0028] In one embodiment, the pawls 160 include a neck portion 116 extending axially downward and being secured along a section of the circular opening in the disc 112. A flange 118 is secured to the neck portion 118 at a right angle, such that the flange 118 extends radially outward, but not inward.

[0029] The applicator face 104 includes a rim 108 on the inner upper side of the applicator face 104. The flanges 118 may fit under the rim 108 such that the applicator face 104 is supported by the flanges 118 while also allowing rotation of the applicator face 104.

[0030] As illustrated in [Fig.4A], in one embodiment, the upper side of the applicator face 104 includes a pair of magnets 121A, 121B respectively placed on opposite sides of the applicator face 104. However, the applicator face 104 may include from one to more than one magnet. In embodiments, the magnets may be placed on the applicator face 104 in diametrically opposed pairs.

[0031] As illustrated in [Fig.4B], the lower side of the housing 102 includes a plurality of magnets 123A-H distributed around the circumference of the annular disc 112. The magnets 123A-H may be distributed in diametrically opposed pairs. The magnets 123A-H are placed at the same radial distance from the center as the magnets 121A, 121B.

[0032] The polarity of the magnets 121A, 121B on the applicator face 104 is opposite the polarity of the magnets 123A-H on the housing 102 to provide attractive forces between the magnets 121A, 121B and the magnets 123A-H. Therefore, the applicator face 104 is not only capable of rotating relative to the housing 102 and the device 100, but also, the applicator face 104 can be held in rotational alignment by the attraction of the pair of magnets 121A, 121B to any pair of the magnets 123A-H. There is resistance to rotation of the applicator face 104 when the pair of magnets 121A, 121B is aligned with any pair of magnets 123A-H.

[0033] The number of magnets on both the applicator face 104 and the bottom of the housing 102 may vary to increase the holding force and / or to define more predefined rotational positions or both.

[0034] In one embodiment, the magnets 123A-H may be used to sense the rotational position of the applicator face 104. The device 100 uses the position of rotating the applicator face 104 to determine whether the roller 115 follows behind the print nozzles 106A, 106B, 106C.

[0035] As illustrated in [Fig.5A], in one embodiment, the applicator face 104 includes a pair of springs 127A and 127B positioned on opposite sides of the applicator face 104 in the radial direction. However, the applicator face 104 may have from one to more than one spring. The springs 127A and 127B may be formed to have a peak in the center with ramped sides leading to the peak. In one embodiment, the peak is directed outward in the radial direction.

[0036] As illustrated in [Fig.5B], the inner periphery of the lower edge of the housing 102 is provided with slots 125. Slots 125 are provided completely around the circumference of the housing 102. Each slot 125 is sized to accommodate the springs 127A and 127B, more particularly, the slots 125 are sized to accommodate the peak of the springs 127A and 127B. The slots are oriented to face radially inward. As the applicator face 104 is rotated, the springs 127A and 127B are compressed and disengage from the slots 125. When rotation is stopped, the springs 127A and 127B re-engage in the corresponding slots 125. Accordingly, the springs 127A and 127B on the applicator face 104 are configured to engage and disengage the slots 125 while rotating the applicator face 104.

[0037] The applicator face 104 is not only capable of rotation relative to the housing 102 and the device 100, but also, the applicator face 104 may be retained in rotational alignment by the springs 127A and 127B engaging the corresponding slots 125 on the housing 102. There is resistance to rotation of the applicator face 104 while the springs 127A, 127B engage the slots 125. The springs 127A and 127B may produce a clicking noise as the springs 127A and 127B are rotated until the springs 127A and 127B fall into the desired rotational alignment.

[0038] The slots 125 may be magnetized to sense the rotational position of the applicator face 104 relative to the device 100. The device 100 uses the rotational position of the applicator face 104 to determine whether the roller 115 is tracking behind the print nozzles 106A, 106B, 106C.

[0039] The mechanisms for maintaining rotational alignment illustrated in FIGURES 4A, 4B, 5A, and 5B enhance the ease of use of the device 100 for applying cosmetics. The device 100 instantly and visibly enhances cosmetic styles through the use of a rotary application and diagnostic system.

[0040] When the applicator face 104 is rotatable, the applicator face 104 can be rotated without having to rotate the entire device 100. The face applicator 104 is rotated so that the device 100 can be moved and the roller 115 follows behind the nozzles 106A, 106B, 106C to avoid smearing.

[0041] The applicator face 104 rotates freely and can be secured in place in any orientation suitable for printing. To change the direction in which the makeup will be applied, the user can rotate the applicator face 104, detach it from the housing 102, until it is in a new suitable position and reattached to the housing 102.

[0042] Alignment of the applicator can be achieved in several ways:

[0043] The applicator face 104 is magnetically secured to the housing 102.

[0044] The applicator face 104 is locked and unlocked from the housing 102.

[0045] The applicator face 104 is held by spring tension and secured in position by slots on the housing 102.

[0046] The applicator face 104 snaps into place by means of an interference fit on the housing 102.

[0047] The direction of travel and orientation of the applicator face 104 are known to the device 100 via feedback from a sensor in the roller 115, the position sensor 122, and the positions of the applicator face 104, such that the device 100 can be programmed to apply makeup only when it is oriented in the correct direction, and the user can be prompted to make rotational adjustments.

[0048] The device 100 improves the appearance of eye makeup through the use of a rotary application and diagnostic system.

[0049] The cosmetic deposition device 100 is configured for application of a cosmetic style to a portion of a biological surface of a subject, and includes the cosmetic deposition assembly 110, at least one position sensor 122, a camera 124, a display 140, and a processor 120 for performing all or part of an operation or method of the disclosure.

In some embodiments, the printing guide further includes one or more alerts to direct the user to move the cosmetic deposition device 100. In some embodiments, the alerts are visual alerts, such as arrows, audible alerts, such as a buzzer or alarm, or tactile alerts such as vibrations.

[0078] Referring to [Fig.7], a method of printing a cosmetic style onto a surface, such as facial features, is illustrated.

[0079] In block 202, the cosmetic deposition device 100 is moved over the surface to be printed with the cosmetic style.

[0080] At block 204, the cosmetic depositing device 100 prints the chosen cosmetic style upon recognizing the location of the facial features.

[0081] At block 206, the cosmetic deposition device 100 senses a direction of the cosmetic deposition device 100 using a direction sensor on the roller 115 coupled to a magnet, or a Hall sensor, or an accelerometer sensor, and the like.

[0082] At block 208, a determination is made, based on the direction of the cosmetic depositing device 100 and the rotational position of the applicator face 104, as to whether or not the roller 115 is following behind the newly printed cosmetic deposit.

[0083] When the determination at block 208 is "yes," meaning that roller 115 follows behind the printing, cosmetic depositing device 100 continues printing and returns to block 204.

[0084] When the determination at block 208 is "no," meaning that the roller 115 is not following behind the newly printed cosmetic deposit, the cosmetic depositing device 100 stops printing at block 210.

[0085] At block 212, the cosmetic deposition device 100 may provide the subject with instructions to rotate the applicator face 104 to the correct position or to a predetermined position.

[0086] At block 214, a determination is made, based on a sensor that detects the position of the applicator face 104, as to whether or not the applicator face 104 has been rotated to the correct or predetermined position. The position of the applicator face 104 may be detected by the magnets 123A-H.

[0087] When the determination at block 214 is "yes," meaning that the applicator face 104 is in the correct rotational position, the cosmetic depositing device 100 continues printing and returns to block 204.

[0088] When the determination at block 214 is "no," meaning that the applicator face 104 is not in the correct rotational position, the cosmetic dispensing device 100 may continue to provide instructions by returning to block 212.

[0089] [Fig.8] is another flowchart of a method 800 of the deposition device cosmetic.

[0090] In block 805, the cosmetic style is moved onto the surface to be printed.

[0091] At block 810, the cosmetic deposition device 100 detects a direction of the cosmetic deposition device 100 using a direction sensor on the roller 115 coupled to a magnet, or a Hall sensor, or an accelerometer sensor, and the like.

[0092] At block 815, one or more indicators are displayed, showing the position of the applicator of the deposition device 100.

[0093] At block 820, the user is instructed to move the position of the applicator of the deposition device 100. In some embodiments, the one or more indicators instruct the user to move the applicator. In some embodiments, the deposition device 100 and / or the external device 1000 are configured to instruct the user to move the applicator.

[0094] At block 825, the cosmetic depositing device 100 prints the chosen cosmetic style upon recognizing the location of the facial features.
