Spray ejection device and digital art system including the same

[0001] The present invention relates to a spray ejection device and a digital art system including the same.

[0002] Painting on canvas or painting on a wall, such as graffiti, is a one-time thing, so it has limited reproducibility and thus its value cannot be sustained, and there is a limitation in that the original cannot be shared with others.

[0003] Advances in IT technology are increasing the need to digitalize and own graffiti and painting works. As part of this trend, interest is growing in systems that can repeatedly reproduce and share one-time artistic value online through digital technology.

[0004] The purpose of the present invention is to provide a digital art system that not only digitizes and stores the final results of a user's work (painting, drawing, sketching, graffiti, etc.), but also identifies and stores the user's characteristics during the work process.

[0005] The technical problems to be solved by the present invention are not limited to the technical problems mentioned above, and other technical problems not mentioned can be clearly understood by a person having ordinary skill in the technical field to which the present invention belongs from the detailed description of the invention below.

[0007] The digital art system according to an embodiment of the present invention may further include an image sensor that senses information including an image of a work projected on the preset target in real time or at a preset cycle. The control unit may match an image on the target acquired through the image sensor at a preset time with first information acquired at a preset time, determine which image is implemented according to the level of the corresponding pressure, and store the result; match an image on the target acquired through the image sensor at a preset time with second information acquired at a preset time, determine which image is implemented at a corresponding position and distance, and store the result; match an image on the target acquired through the image sensor at a preset time with third information acquired at a preset time, and determine which image is implemented according to a corresponding posture.

[0008] The digital art system according to an embodiment of the present invention may further include a biometric information acquisition sensor that senses fourth information, including the user's biometric information, in real time or at preset intervals. The control unit may match an image of a target acquired through the image sensor at a preset time with the fourth information acquired at a preset time, and determine and store which image is implemented based on the user's biometric changes.

[0009] The sensing cycles of the pressure sensor, the distance sensor, the posture tracking sensor, the biometric information acquisition sensor, and the image sensor can be synchronized.

[0010] The spray ejection device may include a housing having an internal receiving space; and a handle rotatably connected to a rotating shaft fixed to the housing and elastically deformed by a user's pressing action to provide a predetermined pressure to a press button of the spray container.

The stopper portion may be elastically deformed or restored to its original state by contacting the partition plate in response to an operating operation of the handle.

[0012] The pressure sensor may be located at least one of the contact portion, the grip portion, and between the stopper portion and the partition plate. The posture tracking sensor may be located at the container fastening portion.

[0013] The digital art system according to an embodiment of the present invention not only stores the final result of a user's work, but also identifies and stores the user's characteristics during the work process, and thus has the advantage of easily creating, storing, and managing works that record the unique characteristics of each user.

[0014] In addition, according to an embodiment of the present invention, since a work recording unique characteristics of each user is stored, specific users who view it can compare and analyze the final result and the work progress in a time series manner, thereby having the advantage of utilizing it in various ways, such as for strengthening their own capabilities and for educational purposes.

[0024] FIG. 1 is a block diagram schematically illustrating a spray injection device and a digital art system including the same according to an embodiment of the present invention. FIG. 2 is a perspective view schematically illustrating a spray injection device according to an embodiment of the present invention. FIG. 3 is a cross-sectional view schematically illustrating a spray injection device according to an embodiment of the present invention.

[0025] Referring to FIGS. 1 to 3, a digital art system (10) according to an embodiment of the present invention may include a spray ejection device (100), a control unit (200), and a sensing unit (210).

[0026] A spray ejection device (100) may include a housing (110) to which a spray container (not shown) is detachably attached, and a handle (150) at least partially accommodated within the housing (110) and elastically deformed by a user's pressing action to provide a predetermined pressure to a pressurizing button of the spray container.

[0027] The housing (110) can determine the outer shape of the spray ejector (100). The housing (110) can provide an internal receiving space. The housing (110) can include an internal receiving space. The internal receiving space of the housing (110) can accommodate a sensor constituting a sensing unit (210) to be described later and a control circuit for controlling the operation of the sensor. The housing (110) can have a gun-shaped outer shape as illustrated, but is not limited thereto. The housing (110) can include a container fastening portion (111) to which a spray container is fastened and a grip portion (115) that a user grips to use the spray ejector (100).

[0028] The container fastening portion (111) provides an internal space that is open toward one side (e.g., downward) to allow the introduction and withdrawal of the spray container, and may include a fixing means for maintaining the fixed state of the introduced spray container. The container fastening portion (111) may be located at the front of the housing (110). Accordingly, the contents discharged from the discharge portion of the spray container fastened to the container fastening portion (111) can be sprayed at a desired location without being affected by other parts of the housing (110). The front may be defined as the direction in which the contents of the spray are sprayed.

[0029] The container fastening portion (111) may further include a container retaining portion (112) and a spray port (113). The container retaining portion (112) may be a fixing means for fixing the introduced spray container in place. The container retaining portion (112) may be formed on the inner circumferential surface of the container fastening portion (111). The spray container may be fastened to the container fastening portion (111) through the container retaining portion (112) in a screw-joint manner, but is not limited thereto. The spray port (113) is a portion that communicates with the discharge portion of the spray container fastened to the container fastening portion (111), and may be a portion through which the contents sprayed through the discharge portion of the spray container pass.

[0030] The handle (150) is rotatably connected to a rotation shaft (120) fixed to the housing (110) and can perform a rotational motion within a preset range around the rotation shaft (120). The handle (150) may include a first body (151) and a second body (155) extending from the first body (151). The first body (151) and the second body (155) may be formed as a single body, but are not limited thereto.

[0031] The first body (151) can be accommodated inside the housing (110), and the second body (155) can extend from the first body (151) so that at least a portion thereof is exposed outside the housing (110).

[0032] The first body (151) can perform a rotational motion within a preset range around a rotational axis (120) fixed to the housing (110). The first body (151) can include a pressure part (151a) formed at one end and a stopper part (151b) formed at the other end around the rotational axis (120).

[0033] One end of the first body (151) can be extended toward the container fastening portion (111) and perform a function of pressing a pressure button of a spray container inserted into the container fastening portion (111) in conjunction with a rotational motion. One end of the first body (151) that presses the pressure button of the spray container can be referred to as a pressure portion (151a).

[0034] The other end of the first body (151) may extend toward the inner surface of the housing (110) to perform a function of limiting the rotational range of the rotational motion to a preset range. Preferably, the housing (110) may include a partition plate (117) that partitions the inner space, and the other end of the first body (151) may be arranged to contact or be spaced apart from the partition plate (117) in response to the rotational motion. The other end of the first body (151) may be referred to as a stopper portion (151b).

[0035] The second body (155) may extend from the first body (151) toward the grip portion (115), and at least a portion thereof may be exposed to the outside of the grip portion (115). A portion of the second body (155) exposed to the outside of the grip portion (115) may be referred to as a contact portion (155a). The contact portion (155a) may be a portion that provides an external force to control the pressurization button of the spray container while the user grips the grip portion (115) when using the spray ejection device (100).

[0036] When an external force is applied by the user to the contact portion (155a), the handle (150) performs a rotational motion in one direction (for example, clockwise with respect to the rotational axis in FIG. 3) within a preset range based on the rotational axis (120). The pressurizing portion (151a) can press the pressurizing button of the spray container in response to the provided external force, and in conjunction therewith, the contents inside the spray container can be sprayed in the form of an aerosol through the injection port (113) from the discharge portion. The stopper portion (151b) can be elastically deformed by contacting the partition plate (117) during the rotational motion of the handle (150), and can limit the rotational motion to a preset range.

[0037] When the external force to the contact portion (155a) is released, the handle (150) performs a rotational motion in the opposite direction (e.g., counterclockwise) within a preset range with respect to the rotation axis (120). That is, when the external force is released, the handle (150) can return to the reference position. The return force for returning to the reference position may be the elastic force of the handle (150). For example, when the stopper portion (151b) is in contact with the partition plate (117) and is elastically deformed, when the external force is released, the stopper portion (151b) can push the partition plate (117) by the elastic force to return the handle (150) to the reference state. If necessary, an additional member such as an elastic member may be provided for returning to the reference position, but is not limited thereto.

[0038] The spray ejection device (100) according to an embodiment of the present invention has a shape that allows a user to easily hold it and easily aim at a spray target area, so that the convenience and ease of use can be significantly improved, and since the spray container is not directly held during operation, it has the advantage of preventing the contents of the container from getting on the hands during the operation of pressurizing the container.

[0039] A spray ejection device (100) according to an embodiment of the present invention and a digital art system (10) including the same may include a control unit (200) and a sensing unit (210).

[0040] The control unit (200) can perform at least one instruction. The control unit (200) performs functions such as calculation, analysis, and comparison, and is electrically connected to at least some of the components of the digital art system (10) to control the overall operation and function of the device. The control unit (200) can be implemented with various circuits capable of performing calculations, such as an MPU (Micro Processor Unit), an MCU (Micro Controller Unit), and an FPGA (field programmable gate array), but is not limited thereto.

[0041] The control unit (200) can store and output the user's results based on the received information such as the pressure level, position, and posture movement of the spray ejector (100) and the analysis information analyzed therefrom, based on the signal obtained from the sensing unit (210). The communication unit (220) can receive the received information and the analysis information from the control unit (200) and transmit them to at least one electronic device (not shown) and / or server using any suitable communication method. The control unit (200) can process signals, data, information, etc. input or output through the spray ejector (100) or run an application program stored in the memory (230), thereby providing or processing appropriate information or functions to the user.

[0042] A power supply unit (not shown) can receive external power or internal power under the control of a control unit (200) and supply power to at least one of the components of a digital art system (10). The power supply unit includes a battery, and the battery may include a built-in battery or a replaceable battery.

[0043] The communication unit (220) may include a short-range communication unit, a long-range communication unit, etc. The short-range communication unit may include, but is not limited to, Bluetooth, BLE (Bluetooth Low Energy), NFC (Near Field Communication unit), WLAN (Wireless Local Area Network), Zigbee, IrDA (Infrared Data Association), WFD (Wi-Fi Direct), UWB (Ultra Wideband), etc. The long-range communication unit may include the Internet, a computer network (e.g., LAN or WAN), and a mobile communication unit. The mobile communication unit may include, but is not limited to, a 3G module, a 4G module, a 5G module, an LTE module, an NB-IoT module, an LTE-M module, etc. The electronic device may include, but is not limited to, a mobile communication terminal, a smart phone, a tablet PC (personal computer), a notebook, a PDA (personal digital assistant), or a wearable device.

[0044] The memory (230) can store a program for processing and controlling the control unit (200), and can also store input / output data. The memory (230) can include at least one type of storage medium among a flash memory type, a hard disk type, a multimedia card micro type, a card type memory (e.g., SD or XD memory, etc.), a RAM (Random Access Memory), a SRAM (Static Random Access Memory), a ROM (Read-Only Memory), an EEPROM (Electrically Erasable Programmable Read-Only Memory), a PROM (Programmable Read-Only Memory), a magnetic memory, a magnetic disk, and an optical disk. In addition, the digital art system (10) can also operate a web storage or cloud server that performs a storage function on the storage Internet.

[0045] The sensing unit (210) may include one or more sensors for sensing at least one of information within the spray ejector (100), information about the surrounding environment of the spray ejector (100), and user information. If necessary, the user information may be input from the user through at least one input unit.

[0046] For example, the sensing unit (210) may include at least one of a proximity sensor, an illumination sensor, a touch sensor, an acceleration sensor, a magnetic sensor, a G-sensor, a gyroscope sensor, a motion sensor, an RGB sensor, an infrared sensor (IR sensor), a fingerprint recognition sensor, an ultrasonic sensor, an optical sensor, an environmental sensor (e.g., a barometer, a hygrometer, a thermometer, etc.), a chemical sensor (e.g., a healthcare sensor, a biometric sensor, etc.), and an image sensor, but is not limited thereto.

[0047] More specifically, when a user performs a task (painting, drawing, sketching, graffiti, etc.) on a preset target (paper, canvas, building wall, etc.) using the spray ejector (100), the sensing unit (210) may sense at least one of distance information between the spray ejector (100) and the preset target, posture information of the spray ejector (100), biometric information of the user, and image information of the task drawn on the preset target (including information on the final result during the task and after the task is completed). To this end, the sensing unit (210) may include a pressure sensor (211), a distance sensor (211), a posture tracking sensor (215), a biometric information acquisition sensor (217), and an image sensor (219).

[0048] The control unit (200) can store, based on the sensing information acquired through the sensing unit (210), at least one of the user's work result information using the spray ejection device (100), history information acquired while the work is in progress to generate the result, and the user's biometric information and surrounding environment information acquired throughout the entire work process as a single digital result by synthesizing the final result.

[0049] The control circuit implementing the control unit (200) is housed within the housing (110) and may be positioned above the partition plate (117). Accordingly, within the housing (110), the control circuit and the handle (150) may be positioned separately at the upper and lower portions with the partition plate (117) interposed therebetween. This may mean that the handle (150), which rotates in response to a provided external force, is not interfered with by the control circuit.

[0050] The pressure sensor (211) can sense first information including pressure information provided by the user to the spray ejector (100) for operation in real time or at a preset cycle. The pressure sensor (211) can be disposed on at least one of the contact portion (155a) of the handle (150) and the grip portion (115) of the housing (110) to sense the pressure level applied by the user. Alternatively, the pressure sensor (211) can be disposed under the partition plate (117) to sense pressure when the stopper portion (151b) of the handle (150) and the partition plate (117) come into contact.

[0051] The pressure applied to the pressure sensor (211) can be matched with the content information (content volume and image information (image area, thickness, shape, etc.) drawn on a preset target corresponding to the content volume) sprayed through the spray ejector (100). The content information can be acquired by the image sensor (219) which will be described later, and / or the content information corresponding to the pressure based on the spray container information can be experimentally data-ized in advance and stored in the memory (230).

[0052] The distance sensor (211) can estimate the position of a preset target that the user wants to work on, and sense second information about the distance between the preset target and the spray ejection device (100) in real time or at preset intervals. The sensing cycle of the first information and the sensing cycle of the second information can be synchronized. The distance sensor (211) may be a TOF (Time of Flight) type sensor using any one of near-infrared, ultrasonic, and laser, but is not limited thereto, and any known distance sensor (211) can be used.

[0053] The distance sensor (211) may be placed at the front of the housing (110). This may mean that the distance between the spray ejector (100) and a preset target located at the front of the spray ejector (100) can be sensed without unnecessary interference from other structures.

[0054] The posture tracking sensor (215) can sense third information about the posture and path (trajectory) corresponding to the movement of the spray ejector (100) in real time or at a preset cycle. The sensing cycle of the first information, the sensing cycle of the second information, and the sensing cycle of the third information can be synchronized. The posture tracking sensor (215) can track the posture and the posture change at a preset time based on the direction in which the contents inside the spray container are sprayed through the spray ejector (100).

[0055] The attitude tracking sensor (215) can sense at least one of the rotational states and translational states of the spray ejector (100). The rotational states may refer to yaw, pitch, and roll, and the translational states may refer to longitude, latitude, altitude, and speed.

[0056] The attitude tracking sensor (215) may include at least one of a three-axis gyroscope, a three-axis accelerometer, and a three-axis magnetometer to measure the rotational motion state of the spray spray device (100), and may include a GPS sensor and a barometric pressure sensor to measure the translational motion state, but is not limited thereto. The attitude tracking sensor (215) may be manufactured as a single chip called an inertial measurement unit (IMU) using a MEMS (MicroElectro-Mechanical Systems) semiconductor process technology, but is not limited thereto, and may be accommodated inside the spray spray device (100).

[0057] The posture tracking sensor (215) may be placed in the container fastening portion (111) of the housing (110). This may mean that the posture tracking sensor (215) is positioned in the container fastening portion (111) to which the spray container is fastened, thereby enabling more accurate sensing of the movement of the spray container.

[0058] The biometric information acquisition sensor (217) can sense the fourth information, including the user's biometric information, in real time or at preset cycles throughout the entire work process. The sensing cycles of the first information, the second information, the third information, and the fourth information can be synchronized. The biometric information acquisition sensor (217) can measure one or more preset biometric information. The biometric information acquired through the biometric information acquisition sensor (217) can include body temperature, blood pressure, electrocardiogram, etc.

[0059] Additionally, the fourth information may include user recognition information. The user recognition information is biometric information for authenticating a user and may include face, hand (fingerprint, etc.), eye (iris, pupil, etc.), etc. The user recognition information for user authentication may be pre-registered and stored in the memory (230). Based on the acquired user recognition information, the control unit (200) may classify and store the aforementioned pressure information, location information, posture tracking information, and biometric information for each authenticated user, and may control the spray ejection device (100) to be operated only by authenticated users.

[0060] The biometric information acquisition sensor (217) may be placed on the grip portion (115) of the housing (110). The grip portion (115) is a portion that the user directly contacts when using the spray ejector (100). This may mean that no separate action is required by the user to sense the user's biometric information. In other words, this may mean that biometric information can be sensed with only basic actions for using the spray ejector (100).

[0061] The image sensor (219) can sense fifth information, including a workpiece image projected onto a preset target, in real time or at preset cycles. The control unit (200) can match the image and video information acquired from the image sensor (219) with the first to fourth information.

[0062] For example, the control unit (200) can match an image on a target acquired at a preset time with first information, i.e., pressure information, acquired at the preset time, and determine and store which image is implemented according to the level of the corresponding pressure. In addition, the control unit (200) can match an image on a target acquired at a preset time with second information, i.e., location information, acquired at the preset time, and determine and store which image is implemented at the corresponding location and distance. In addition, the control unit (200) can match an image on a target acquired at a preset time with third information, i.e., posture information, acquired at the preset time, and determine and store which image is implemented according to the corresponding posture. In addition, the control unit (200) can match an image on a target acquired at a preset time with fourth information, i.e., biometric information, acquired at the preset time, and determine and store which image is implemented according to changes in the biometric properties of the user.

[0063] The control unit (200) can record and store the entire life cycle of a user's work by matching information acquired by various sensors with the workpiece during the user's work, showing what kind of workpiece can be created in what environment, and can also store the final result. The control unit (200) can transmit the stored user-specific data to at least one electronic device or server via the communication unit (220).

[0064] Accordingly, the digital art system (10) according to the embodiment of the present invention not only stores the final result of the user's work, but also identifies and stores the user's characteristics during the work process, so it has the advantage of being able to easily create, store, and manage works that record the unique characteristics of each user.

[0065] In addition, according to an embodiment of the present invention, since a work recording unique characteristics of each user is stored, specific users who view it can compare and analyze the final result and the work progress in a time series manner, thereby having the advantage of utilizing it in various ways, such as for strengthening their own capabilities and for educational purposes.

[0066] It will be apparent to those skilled in the art that the present invention can be embodied in other specific forms without departing from the essential characteristics thereof. Therefore, the above detailed description should not be construed as limiting in any respect, but rather as illustrative. The scope of the present invention should be determined by a reasonable interpretation of the appended claims, and all modifications within the scope of equivalents of the present invention are intended to be included within the scope of the present invention.
