[0031] The disclosure relates to a cosmetic deposition device 100 used to imprint 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 a right angle to the handle 135. In one embodiment, the housing 102 is a shaped housing cylindrical having a display 140 at one end of the housing and an applicator face 104 at the opposite end of the display 140.
[0032] 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.
[0033] 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.
[0034] The print head 145 is visible through an opening in the applicator face 104. In particular, 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.
[0035] With reference to Figures 4A and 4B, the cosmetic deposition assembly 110 includes the applicator face 104 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.
[0036] In one embodiment, the print head 145 includes three rows 106A, 106B, and 106C of nozzles ([Fig. 3]). Each row 106A, 106B, and 106C of nozzles 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 106A, 106B, and 106C of nozzles is configured to dispense a single formulation from the corresponding cartridge 119A, 119B, and 119C.
[0037] 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 fixed to the underside of the housing 102. When the cosmetic deposition 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 distribute the formulation onto the surface. To avoid smearing, it is desirable that the cosmetic deposition device 100 be moved in a direction so that the roller 115 follows behind the rows 106A, 106B, and 106C of nozzles.
[0038] In one embodiment, the applicator face 104 includes a rotation mechanism for the applicator face 104, independent of the entire cosmetic deposition device 100. This allows makeup to be applied in any direction without changing the orientation of the entire cosmetic deposition device 100.
[0039] As illustrated in Figures 4B and 5B, the underside 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 another embodiment, the print head 145 does not rotate with the applicator face 104.
[0040] 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.
[0041] In one embodiment, the ratchets 160 include a collar 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 collar portion 116 at a right angle, so that the flange 118 extends radially outwards, but not inwards.
[0042] 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.
[0043] 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.
[0044] As illustrated in [Fig. 4B], the underside 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.
[0045] 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 in order to exert attractive forces between the magnets 121A, 121B and the magnets 123A-H. Consequently, the applicator face 104 is not only able to rotate relative to the housing 102 and the cosmetic deposition device 100, but the applicator face 104 can also be held in rotational alignment by the attraction of the pair of magnets 121A, 121B. towards any pair of magnets 123A-H. A resistance to rotation of the applicator face 104 is present when the pair of magnets 121 A, 121B is aligned with any pair of magnets 123A-H.
[0046] 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.
[0047] In one embodiment, the magnets 123A-H can be used to capture the rotation position of the applicator face 104. The cosmetic deposition device 100 uses the rotation position of the applicator face 104 to determine whether the roller 115 follows behind the rows 106A, 106B, 106C of printing nozzles.
[0048] 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 one or more springs. The springs 127A and 127B may be shaped to have a peak in the center with inclined sides leading to the peak. In one embodiment, the peak is directed outward in the radial direction.
[0049] As illustrated in [Fig. 5B], the inner periphery of the underside edge of the housing 102 has slots 125. Slots 125 are present around the entire 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 during rotation of the applicator face 104.
[0050] The applicator face 104 is not only capable of rotating relative to the housing 102 and the cosmetic deposition device 100, but the applicator face 104 can also be held in rotational alignment by the springs 127A and 127B engaging with the corresponding slots 125 on the housing 102. A resistance to rotation of the applicator face 104 is present while the springs 127A and 127B are engaging with the slots 125. The springs 127A and 127B can produce a clicking noise as they are rotated until they reach the desired rotational alignment.
[0051] The slots 125 can be magnetized to capture the rotational position of the applicator face 104 relative to the cosmetic deposition device 100. The cosmetic deposition device 100 uses the rotational position of the applicator face 104. to determine if roller 115 follows behind rows 106A, 106B, 106C of print nozzles.
[0052] The mechanisms for maintaining rotational alignment illustrated in FIGURES 4A, 4B, 5A, and 5B improve the ease of use of the Cosmetic Deposition Device 100 for applying cosmetics. The Cosmetic Deposition Device 100 instantly and visibly enhances cosmetic styles through the use of a rotary diagnostic and application system.
[0053] When the applicator face 104 is capable of rotating, the applicator face 104 can be rotated without having to rotate the entire cosmetic deposition device 100. The applicator face 104 is rotated so that the cosmetic deposition device 100 can be moved and the roller 115 follows behind the rows 106A, 106B, 106C of nozzles to avoid smears.
[0054] The applicator face 104 rotates freely and can be fixed 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.
[0055] Applicator alignment can be achieved in several ways:
[0056] The applicator face 104 is magnetically attached to the housing 102.
[0057] The applicator face 104 is locked onto the housing 102 and unlocked from it- here.
[0058] The applicator face 104 is held by a spring tension and immobilized by slots on the housing 102.
[0059] The applicator face 104 snaps into place by means of a tightening adjustment on the housing 102.
[0060] The direction of movement and the orientation of the applicator face 104 are known to the cosmetic deposition 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 cosmetic deposition 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.
[0061] The cosmetic deposition device 100 enhances eye makeup by using a rotating diagnostic and application system.
[0062] The cosmetic deposition device 100 is configured for the 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 to perform all or part of an operation or method of disclosure.
[0063] The position sensor 122 can detect a position of the rows 106A-C of nozzles relative to the portion of the biological surface.
[0064] The circuit set of the cosmetic deposition device 100, which includes but is not limited to a processor, a microprocessor, a processor circuit set, and / or a dedicated hardware circuit set, operationally connects the cosmetic deposition assembly 110, the print head 145, the applicator face 104, the position sensor 122, the camera 124, and, when present in one embodiment, the display 140. The circuit set is configured to instruct the cosmetic deposition assembly 110 to print the cosmetic style with the print head 145, calculate the position of the cosmetic deposition device 100 relative to the portion of the biosurface based on the position sensor 122, and calculate the selective activation of one or more nozzles in rows 106A-C based on the position of the cosmetic deposition device 100 relative to the portion of the biological surface.In some embodiments, the circuit set of the cosmetic deposition device 100 is configurable with a processor and instructions executable by the processor stored on a machine-readable non-transient medium of the cosmetic deposition device 100, by way of non-limiting example.
[0065] Sensors for determining position, direction and alignment of rotation may include magnetic field sensors, Hall effect sensors, accelerometers, resistive sensors, inductive sensors, and the like.
[0066] In some embodiments, the cosmetic deposition device 100 includes a processor 120 for executing instructions stored on a non-transient, computer-readable medium, enabling the processor to perform all or part of a disclosure method or process. In some embodiments, the processor 120 is configured to receive a makeup image file, detect the position and curvature of a portion of a subject's surface based on the position sensor 122, and instruct the print head 145 to print a cosmetic style based on the makeup image file at a location on the skin surface. A plurality of facial features of the subject's image are recognized, for example, by a software application on a computer device 1000 analyzing the image.In some embodiments, the plurality of facial features are recognized by the cosmetic deposition device 100, via one or more cameras 124 on the cosmetic deposition device 100. In some embodiments, the depth and / or curvature of the plurality of facial features are recognized by the position sensor 122.
[0067] In some embodiments, the location is determined by a cosmetic style. For example, a cosmetic lipstick style can be printed on the subject's lips, an eyebrow cosmetic style can be printed on the subject's eyebrow, a Cosmetic style eyeshadow can be printed on the subject's eyelid, and similar.
[0068] In some embodiments, a position sensor is located inside the roller 115. In some embodiments, the camera 124 is configured to capture a plurality of images as the cosmetic deposition device 100 moves over a portion of skin, such as a facial feature of a subject.
[0069] In some embodiments, the applicator face 104 is configured to articulate via flexible ratchets 160. The articulation of the applicator face 104 allows for more precise scanning of a surface. In such embodiments, during operation, a position sensor inside the roller 115 comes into contact with the surface and rolls as the cosmetic deposition device 100 scans the surface. In such embodiments, the cosmetic deposition device 100 is capable of compensating for the curvature of the surface.
[0070] The display 140 is configured for use as a user interface. Although the display 140 is shown on the rear side of the cosmetic deposition device 100, in some embodiments, the display 140 is a separate component, such as a smartphone or tablet. In some embodiments, the display 140 includes one or more actuators, such as buttons or keys. In some embodiments, the display 140 includes a capacitive touch button. In some embodiments, the display 140 is a touchscreen.
[0071] A position sensor can be configured to roll over the facial feature as the cosmetic deposition device 100 is moved over the facial feature. In this way, the position sensor detects the position of the facial feature as the cosmetic deposition device 100 moves over it. In some embodiments, the position sensor in the roller 115 is further configured to detect the curvature of the facial feature or the subject's face, i.e., the portion of the subject's biological surface.
[0072] Formulation cartridges 119A, 119B, and 119C are configured to contain one or more cosmetic inks or dyes, or other compositions for cosmetic styling. Formulation cartridges 119A, 119B, and 119C can contain any number of colors, compositions, finishes, or formulations of cosmetic inks or dyes.
[0073] In embodiments, the processor 120 of the cosmetic deposition device 100 is configured to generate instructions based on one or more inputs associated with the cosmetic style which cause the print head 145 to distribute and deposit a cosmetic formulation according to the cosmetic style chosen and modified by a subject.
[0074] Fig. 6 is an illustration of a cosmetic style printing system 2000 which can be implemented with the cosmetic deposition device 100 and a computer device 1000, such as a smartphone which includes a set of circuits configured to select the cosmetic style from a plurality of cosmetic styles, display the cosmetic style on an image of the portion of the subject's biological surface, and transmit the cosmetic style as a makeup image file to the cosmetic deposition device 100.The circuit set of the cosmetic deposition device 100 is operationally connected (or is operationally connectable) to the circuit set of the computer device 1000 and is further configured to receive the makeup image file from the computer device 1000 and instruct the print head 145 to print the cosmetic style with the formulations from the formulation cartridges by actuation of the nozzles in rows 106A-C on the basis of the makeup image file.
[0075] In some exemplary embodiments, the computing device 1000 is a smartphone or other consumer computing device and the circuitry of the computing device 1000 is configurable with a processor or microprocessor programmable with processor-executable instructions stored on a machine-readable nontransient medium of the computing device 1000.
[0076] Accordingly, in embodiments, the computer device 1000 includes a software application configured to select a cosmetic style from a plurality of cosmetic styles, display the cosmetic style on an image of a portion of the subject's skin, and transmit the cosmetic style as a makeup image file via a wireless connection, such as a Bluetooth® connection, a Bluetooth® Low Energy (BLE) connection, and / or a Wi-Fi® connection and / or a wired connection.
[0077] In some embodiments, a software application for the computer device 1000 displays a plurality of cosmetic styles, such as eyebrow shapes, lip shapes, etc., on a display of the computer device 1000. A user selects a cosmetic style from among the plurality of cosmetic styles by clicking, tapping, or otherwise choosing the cosmetic style on the computer device 1000. In some embodiments, the software application displays the plurality of cosmetic styles as a list or drop-down menu.
[0078] The software application on the computer device 1000 can display an image of the subject's face configured to represent a superimposition of a cosmetic style onto a biological surface of the face, for example, an eyebrow. In some embodiments, the image is a live video stream from a camera of the computer device 1000 or from a camera 124 of the cosmetic deposition device 100.
[0079] The computer device 1000 displays an image of the subject's face and cosmetic styles. The subject selects a cosmetic style, which is then superimposed on the subject's face. The subject may make adjustments, or adjustments may be recommended by the computer device 1000, based on the subject's face shape, the shape of a facial feature, the subject's hair, skin, eye, or clothing color, or a trending adjustment, for example, an adjustment that is being applied by one or more subjects. In some embodiments, adjusting the selected cosmetic style includes changing the color, size, length, width, hair length, pattern, angle, position, location, or a combination thereof, of the selected cosmetic style.
[0080] Once the subject is satisfied with the chosen cosmetic style, the subject can transmit the cosmetic style as a makeup image file to the cosmetic deposition device 100. The subject then applies the chosen and / or adjusted cosmetic style to a surface with the cosmetic deposition device 100.
[0081] The cosmetic application device 100 receives the makeup image file of the selected cosmetic style from the computer device 1000. The subject can hold the cosmetic application device 100 by the handle and move it across a surface. As the cosmetic application device 100 is moved across the surface, it detects the position and curvature of the body based on one or more positions and instructs the printer to print the cosmetic style at a specific location.
[0082] In some embodiments, the cosmetic deposition device 100 provides instructions to rotate the applicator face 104 to a predetermined position. In some embodiments, the cosmetic deposition device 100 detects the direction of movement of the applicator face 104 and stops printing if it detects that the roller 115 is not following behind the nozzles. The cosmetic deposition device 100 provides instructions to rotate the applicator face 104 to a predetermined position. Once it detects that the applicator face 104 is in the correct orientation, the cosmetic deposition device 100 allows printing to begin or continue.
[0083] In some embodiments, the chosen cosmetic style may require that the cosmetic deposition device 100 be directed in more than one direction on the surface. For example, vertically and horizontally.
[0084] 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, and then move the cosmetic deposition device 100 in a second direction on the surface, such as vertically.
[0085] In some embodiments, the display 140 is configured to display a print guide to help a user correctly operate the cosmetic deposition device 100. The print guide may include an arrow pointing in a direction in which a user can move the cosmetic deposition 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 deposition device 100.
[0086] In some embodiments, the display 140 shows a current view from the camera 124 onto the cosmetic deposition device 100. In some embodiments, as the user moves the cosmetic deposition device 100 across the surface, an image captured by the camera 124 is displayed. In some embodiments, the printer guide further includes one or more alerts to prompt the user to move the cosmetic deposition device 100. In some embodiments, the alerts are visual, such as arrows; audible, such as a beep or alarm; or tactile, such as vibrations.
[0087] With reference to [Fig.7], a method 200 for printing a cosmetic style on a surface, such as facial features, is illustrated.
[0088] At block 202, the cosmetic deposition device 100 is moved onto the surface on which the cosmetic style is to be printed.
[0089] At block 204, the cosmetic deposition device 100 prints the cosmetic style chosen during the recognition of the location of the facial features.
[0090] At 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 effect sensor, or an accelerometer sensor, and the like.
[0091] 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.
[0092] 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.
[0093] 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.
[0094] 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.
[0095] 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.
