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 a right angle to the handle 135. In one embodiment, the housing 102 is a cylindrical housing having a display 140 at one end of the housing and an applicator face 104 at the opposite end from the display 140.

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

[0020] With reference to [Fig. 2], the applicator face 104 is part of a cosmetic deposition assembly 110 which also includes a print head 145. The applicator face 104 includes an elongated roller 115 which 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 separated from the surface.

[0021] The print head 145 is visible through an opening in the applicator face 104. In particular, the rows 106A, 106B, 106C of nozzles of the print head 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] With reference 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 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 from Prinker Korea Inc. discloses a printing technology.

[0023] In one embodiment, the print head 145 includes three rows 106A, 106B, and 106C of nozzles ([Fig. 3]). Each row 106A, 106B, and 106C can include up to hundreds of nozzles, which can 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 used, the applicator face 104 maintains contact with a surface via the roller 115 to ensure proper spacing from the surface and smooth movement across the surface. The applicator face 104 includes an opening allowing the rows 106A, 106B, and 106C of nozzles to dispense the formulation onto the surface. To avoid smearing, it is desirable that the device 100 be moved in such a direction that the roller 115 follows behind the rows 106A, 106B, and 106C of nozzles.

[0025] In one embodiment, the applicator face 104 includes a rotation mechanism for 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 print head 145. In one embodiment, the print head 145 can be fixed to the applicator face 104 and rotate together with the applicator face 104. In a In this embodiment, the print head 145 does not rotate with the applicator face 104.

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

[0028] In one embodiment, the ratchets 160 include a neck portion 116 extending axially downwards and being fixed along a section of the circular opening in the disc 112. A flange 118 is fixed to the neck portion 118 at a right angle, so that the flange 118 extends radially outwards, but not inwards.

[0029] The applicator face 104 includes a rim 108 on the inner upper side of the applicator face 104. The flanges 118 can fit under the rim 108 so 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 placed respectively on opposite sides of the applicator face 104. However, the applicator face 104 may include one or more magnets. In some 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 disk 112. The magnets 123A-H can be arranged in diametrically opposed pairs. The magnets 123A-H are positioned 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 to 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 able to rotate 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 towards any pair of 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 at once on the applicator face 104 and the underside of the housing 102 can vary to increase the holding force and / or to define more predefined rotation positions or both.

[0034] In one embodiment, the magnets 123A-H can be used to capture the rotational position of the applicator face 104. The device 100 uses the position of rotation of applicator face 104 to determine if roller 115 follows behind 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 shaped 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 dimensioned to accommodate the springs 127A and 127B; more specifically, the slots 125 are dimensioned to accommodate the peaks of the springs 127A and 127B. The slots are oriented to point radially inward. As the applicator face 104 is rotated, the springs 127A and 127B are compressed and disengage from the slots 125. When the rotation is stopped, the springs 127A and 127B re-engage in the corresponding slots 125. Therefore, the springs 127A and 127B on the applicator face 104 are configured to engage with and disengage from the slots 125 while rotating the applicator face 104.

[0037] 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 springs 127A and 127B engaging with the corresponding slots 125 on the housing 102. There is resistance to the rotation of the applicator face 104 while the springs 127A and 127B are engaged with the slots 125. The springs 127A and 127B can produce a rattling noise as they are rotated until they fall into the desired rotational alignment.

[0038] The slots 125 can be magnetized to capture the rotation position of the applicator face 104 relative to the device 100. The device 100 uses the rotation position of the applicator face 104 to determine whether the roller 115 follows behind the printing nozzles 106A, 106B, 106C.

[0039] The mechanisms for maintaining rotational alignment illustrated in FIGURES 4A, 4B, 5A, and 5B improve the ease of use of Device 100 for applying cosmetics. 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 capable of rotating, the applicator face 104 can be rotated without having to rotate the entire device 100. The face The 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 burrs.

[0041] The applicator face 104 rotates freely and can be locked in place in any suitable orientation 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 then reattach it to the housing 102.

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

[0043] The applicator face 104 is magnetically attached 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 a spring tension and secured in positioning by slots on the housing 102.

[0046] The applicator face 104 snaps into place by means of a tightening adjustment on the housing 102.

[0047] The direction of movement and the orientation of the applicator face 104 are known to the device 100 by means of feedback from a sensor in the roller 115, the position sensor 122 and the positions of the applicator face 104, so 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 rotation adjustments.

In some embodiments, the cosmetic deposition device 100 detects the direction of movement of the cosmetic deposition device 100 and stops printing if the roller 115 is detected as not following behind the nozzles. The cosmetic deposition device 100 provides instructions to rotate the applicator face 104 to a predetermined position. Once the applicator face 104 is detected as being in the correct orientation, the cosmetic deposition device 100 allows printing to start or continue.

[0074] In some embodiments, the chosen cosmetic style may require that the cosmetic application device 100 be directed in more than one direction on the surface. For example, vertically and horizontally.

[0075] In embodiments, the cosmetic deposition device 100 can provide instructions to move the cosmetic deposition device 100 in a first direction on the surface, such as horizontally, and then provide instructions to rotate the applicator face 104, for example by 90 degrees, then moving the cosmetic deposition device 100 in a second direction on the surface, such as vertically.

[0076] In some embodiments, the display 140 is configured to display a print guide to instruct a user to correctly use the cosmetic application device 100. The print guide may include an arrow pointing in a direction in which a user can move the cosmetic application device 100. In some embodiments, the print guide includes a graphic representation of the facial feature and an arrow pointing in the direction in which a user can move the cosmetic application device 100.

[0077] In some embodiments, the display 140 shows a current view from the camera 124 onto the cosmetic application device 100. In some embodiments, as the user moves the printing device 100 across the surface, an image captured by the camera 124 is displayed. In some embodiments, the printing guide further includes one or more alerts to instruct the user to move the cosmetic application device 100. In some embodiments, the alerts are visual, such as arrows; audible, such as a beep or alarm; or tactile, such as vibrations.

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

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

[0080] At block 204, the cosmetic deposition device 100 prints the cosmetic style chosen during the recognition of the location of facial features.

[0081] In block 206, the cosmetic deposition device 100 captures 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 deposition device 100 and the rotation position of the applicator face 104, to determine whether the roller 115 follows behind the newly printed cosmetic deposit or not.

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

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

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

[0086] In block 214, a determination is made, based on a sensor that detects the position of the applicator face 104, making it possible to determine whether the applicator face 104 has been rotated to the correct or predetermined position. The position of the applicator face 104 can 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 rotation position, the cosmetic deposition 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 rotation position, the cosmetic deposition device 100 can continue to provide instructions by returning to block 212.

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

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

[0091] At block 810, the cosmetic deposition device 100 detects a direction of the cosmetic deposition device 100 using a direction sensor on 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 receives the command to move the position of the applicator of the deposition device 100. In some embodiments, one or more Indicators instruct the user to move the applicator. In some embodiments, the dispensing device 100 and / or the external device 1000 are configured to instruct the user to move the applicator.

[0094] At block 825, the cosmetic deposition device 100 prints the cosmetic style chosen during the recognition of the location of facial features.
