In the description of the present invention, when it is determined that specific description of related known technologies may lead to unclear gist of the present invention, detailed description thereof will be omitted.
Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
Fig. 1 is a block diagram showing a configuration of a skin management device according to an embodiment of the present invention, and fig. 2 is a schematic perspective view of the skin management device according to an embodiment of the present invention.
Referring to fig. 1 and 2, a skin management device 1 according to an embodiment of the present invention may include a main body 100, a control unit 200, and a storage unit 300.
In various embodiments of the present invention, the skin management device 1 is a current stimulator that applies current stimulation to the skin of a user to massage the skin of the user or to help absorb cosmetics. However, the skin management device 1 of the present invention is not limited to the current stimulator, and may include any device that applies stimulation to a contact object by using an output current.
The main body 100 constitutes the appearance of the skin management device 1 of the present invention, and is made of synthetic resin of various materials. In various embodiments of the present invention, the main body 100 has a gentle curved surface shape as shown in fig. 2, and the image feeling can be further improved.
The main body 100 includes a 1 st contact 110 and a 2 nd contact 120 that output current and transmit the current to a contact object under the control of the control unit 200.
The 1 st contact part 110 is formed at the upper end of the main body part 100. In the main body portion 100, a region where the 1 st contact portion 110 is formed is named a head portion. The head is configured to deliver current stimulation to a desired location by the user contacting the skin.
The 2 nd contact part 120 is formed at one side surface or a lower end of the main body part 100. In the main body 100, a region where the 2 nd contact portion 120 is formed is named as a grip portion. The grip portion may be configured to allow a user to conveniently hold the main body portion 100.
In various embodiments, a plurality of 2 nd contacts 120 may be provided.
The 1 st contact 110 and the 2 nd contact 120 may include at least one electrode 111, 121. The electrodes 111 and 121 may be made of a metal material to output a current under the control of the control unit 200.
In one embodiment, at least one electrode 111 constituting the 1 st contact 110 is formed along the circumference of the 1 st contact 110. In one embodiment, at least one electrode 121 constituting the 2 nd contact part 120 is formed along the axis of the body part 100.
The main body 100 has a ground portion, and the 1 st contact portion 110 and the 2 nd contact portion 120 form a closed circuit with the skin of the user in contact therewith. The output current of the 1 st contact 110 and the 2 nd contact 120 is transmitted to the skin of the user in contact with them in the form of cations or anions through a closed circuit.
In particular, the output current of the 1 st contact part 110 may impart various cosmetic effects to the skin of the user.
For example, the output current of the 1 st contact part 100 is transmitted to the muscle inside the skin of the user to guide the contraction and relaxation of the muscle.
Alternatively, in one embodiment, the 1 st contact 110 may output a galvanic Current (galvanic Current) as the output Current. The galvanic current, which is a direct current for maintaining the direction and magnitude of the current constant in the range of 0.5mA to 1mA, can impart a cosmetic effect of allowing the active ingredients of the cosmetics to reach the dermis layer of the user's skin or discharging waste.
In one embodiment, the 1 st contact 110 may output a micro current as an output current. The micro-current is a direct current that maintains the direction and magnitude of the current constant as a current of less than 0.5mA, and can achieve various cosmetic effects such as decomposition of fat cells in the skin of a user, synthesis of collagen, promotion of blood circulation, massage, and the like.
In one embodiment, the 1 st contact 110 may output a high frequency (tesla current) as an output current. The high frequency is a high alternating current having a frequency of 100,000Hz or more, and can achieve a cosmetic effect such as promotion of blood circulation of the skin of a user, sterilization and disinfection effects, improvement of scars, and the like.
In one embodiment, the 1 st contact 110 outputs ultrasonic waves as an output current. Ultrasonic waves are used as a very high alternating current having a frequency of 200,000Hz or more, and can achieve a cosmetic effect such as lifting and massaging of the skin of a user, improvement of blood circulation, and relaxation of muscles.
In various embodiments, the 1 st contact part 110 may output a low frequency having an effect of increasing elasticity and decomposing fat to the skin of the user, a middle frequency having a strong muscle movement and massage effect through metabolism/blood circulation, and the like.
Although the above description has been given by taking a few examples of the output current of the 1 st contact 110, the output current of the 1 st contact 110 is not limited to the above, and the 1 st contact 110 may output various currents different according to the skin beauty effect.
The type of current output by the 1 st contact 110 is set in advance during the manufacturing process of the skin care apparatus 1 or determined by user input through operation of the button portion 130.
In various embodiments of the present invention, the control unit 200 senses whether the contact with the portion where the user wants to transmit the current stimulation is made through the 1 st contact 110, and senses whether the user holds the touch panel by the hand through the 2 nd contact 120.
For example, the control unit 200 may detect the resistance value corresponding to the output current of each of the 1 st contact unit 110 and the 2 nd contact unit 120 by a closed circuit formed by the 1 st contact unit 110 and the 2 nd contact unit 120, the skin of the user contacting them, and the ground. The control part 200 senses whether the user's skin is in contact with the 1 st contact part 110 and the 2 nd contact part 120 by the variation of the resistance value.
In the above description, the case where the 2 nd contact part 120 senses whether the user's skin is in contact or not based on the change in the electrical characteristics like the 1 st contact part 110 has been described as an example, but the technical idea of the present invention is not limited thereto, and in each of the embodiments, the 2 nd contact part 120 may sense whether the user's skin is in contact or not based on the change in the brightness, the change in the pressure, or the like. This is to control the operation of the skin management device 1 by sensing whether or not the 2 nd contact portion 120 is in contact even when the user uses the skin management device 1 in various states such as wearing gloves.
On the other hand, in various embodiments of the present invention, the 1 st contact part 110 may further include a vibration part 112 transmitting a vibration force to a contact object. The vibration part 112 may be provided at a central portion of at least one electrode 111 formed along the periphery of the 1 st contact part 110.
By transmitting the vibration force to the contact object of the 1 st contact part 110, a massage effect on the contact object can be achieved. The vibration unit 112 can transmit a beat (tap) to the contact object as an example of the vibration force.
The driving unit that generates the vibration force of the vibration unit 112 is provided inside the main body 110. In each embodiment of the present invention, the driving unit converts the rotational motion of the driving motor into a linear reciprocating motion. The vibration unit 112 transmits the linear reciprocating motion generated by the driving unit to the contact object, thereby realizing a tapping massage effect.
In various embodiments of the present invention, the main body 100 may include a button 130 for receiving an input from a user. The button portion 130 can receive an input from a user for operating a control operation of the control portion 200. For example, the button unit 130 receives an input for performing on/off control of the skin management device 1, an input for controlling the magnitude of the output current of the 1 st contact unit 110, an input for controlling the type and intensity of the vibration motion of the vibration unit 112, and the like.
In addition, a terminal portion 140 may be provided at a lower end of the main body portion 100. The main body 100 may include a rechargeable battery (not shown) therein, and the terminal portion 140 may be a portion where one end of the battery is exposed to the outside of the main body 100. Such a battery can be charged by supplying a voltage necessary for driving the control unit 200 described later and by coupling the terminal unit 140 to the charger terminal.
Here, the skin management device 1 according to one embodiment of the present invention has been described by taking as an example a case where it includes a rechargeable battery, but the present invention is not limited to this, and the terminal portion 140 may be omitted outside the main body portion 100, and power may be applied to the control portion 200 by a replacement battery.
The control unit 200 and the storage unit 300 may be provided inside the main body 100. The control unit 200 is connected to the 1 st contact 110 and the 2 nd contact 120 and controls the output current to the 1 st contact 110 and the 2 nd contact 120.
When the skin management device 1 is switched to the on state by the input of the input section 130, the control section 200 may first control the management device 1 to the standby mode.
As shown in fig. 3, the control unit 200 controls (31) the 1 st contact 110 and the 2 nd contact 120 in the standby mode so that the 1 st contact 110 and the 2 nd contact 120 output a minimum current (hereinafter, referred to as a 1 st minimum current) required for sensing whether the user's skin is in contact or not. At this time, the 1 st minimum current is a predetermined current, and may be set as a standby current of a minimum magnitude for sensing whether the skin is in contact with the 1 st contact 110 and the 2 nd contact 120. In one embodiment, the 1 st minimum current may be a micro current of 0.1mA or less. As a result, in the standby mode, the skin management effect cannot be achieved even if the skin of the user receives the output current of the 1 st contact part 110. In addition, in various embodiments of the present invention, the 1 st minimum current of the 1 st contact 110 and the 2 nd contact 120 may be set to be different from each other.
The control unit 200 can detect the resistance value of the closed circuit including the 1 st contact 110 and the 2 nd contact 120 in the standby mode. The control part 200 may sense whether the user's skin is in contact with the 1 st contact part 110 and the 2 nd contact part 120, respectively, based on the detected change in the resistance value. Specifically, in the case where the resistance value of the closed circuit increases above a preset threshold value, the control part 200 may sense that the skin of the user is in contact with the corresponding contact part.
In various embodiments of the present invention, the control unit 200 controls the skin management device 1 to the operation mode (32) when it is sensed that the skin of the user is in contact with both the 1 st contact part 110 and the 2 nd contact part 120. That is, as shown in fig. 3, when the skin of the user is in contact with only one of the 1 st contact part 110 and the 2 nd contact part 120, the control part 200 can still control the skin management device 1 to the standby mode (31).
In one embodiment, when the plurality of 2 nd contact portions 120 are provided, the control portion 200 may control the skin management device 1 to the operation mode when it is sensed that the skin of the user is in contact with both the 1 st contact portion 110 and the plurality of 2 nd contact portions 120.
As shown in fig. 3, when the operation mode is entered, the control unit 200 controls the 1 st contact unit 110 to output a current (hereinafter, referred to as a 2 nd minimum current) for applying a current stimulus of a minimum magnitude to the skin of the user in contact with the 1 st contact unit 110 to achieve a cosmetic effect such as a massage effect, a cosmetic absorption effect, and a waste discharge effect. The 2 nd minimum current is determined in advance as a value larger than the 1 st minimum current by an experiment of the cosmetic effect of the skin management device 1.
In various embodiments of the present invention, the control unit 200 controls the 1 st contact unit 110 to output various currents such as galvanic current, micro current, high frequency, intermediate frequency, low frequency, and ultrasonic wave, which provide a cosmetic effect to a contact object, in the operation mode.
The type of current output by the 1 st contact 110 may be preset during the manufacturing process of the skin management device 1 or determined by user input through operation of the button 130.
After that, the control unit 200 controls the 1 st contact 110 to gradually increase the output current until the set final output current level is reached (33).
After the skin management device 1 is switched to the open state, the control part 200 may receive a user input for controlling the final output current of the 1 st contact part 110 through the input part 130. Alternatively, the control part 200 may receive a user input for controlling the current output mode of the 1 st contact part 110 through the input part 130, and determine a final output current predetermined corresponding to the received input. Alternatively, the control part 200 may determine the predetermined final output current regardless of the user input.
The control part 200 may gradually increase the output current of the 1 st contact part 110 from the 2 nd minimum current to the final output current. At this time, the increase of the output current of the 1 st contact 110 may be controlled to increase in a linear, curved or stepped shape, and as the information for controlling the increase of the output current, an increase time (period), an increase speed, an increase size, and the like may be previously set.
Here, the increase time may represent a time required for increasing the 2 nd minimum current to the set final output current, the increase period may represent a current increase period when increasing in steps, the increase speed may represent an amount of current increase per a preset time, and the increase size may represent an amount of current increase per one increase.
For example, when the 2 nd minimum current is set to 0.5mA, the increase time of the output current is set to 2 seconds, and the final output current is set to 1mA of minute current, the control unit 200 controls the 1 st contact unit 110 to output 0.5mA of current when the operation mode of the skin management device 1 is switched, and thereafter controls the 1 st contact unit 110 to increase the output current by 0.25mA per second for 2 seconds.
As described above, the skin management device 1 according to an embodiment of the present invention does not output the set final output current immediately after entering the operation mode, but gradually increases the output current from the 2 nd minimum current to the set final output current, thereby enabling the skin management device to exhibit the effect without giving the user a feeling of discomfort due to sudden current stimulation.
In such an operation mode, the control unit 200 controls the 2 nd contact unit 120 to output the 1 st minimum current for detecting whether the user is in contact with the skin.
Thereafter, as shown in fig. 3, the control part 200 may control the output current of the 1 st contact 110 based on the resistance value detected through the closed loop of the 1 st contact 110.
In the case where the cosmetic applied to the skin of the user in contact with the 1 st contact part 110 is absorbed or evaporated by the skin or as waste is secreted from the skin of the user, the resistance value detected through the closed circuit of the 1 st contact part 110 may be changed. The control part 200 increases or decreases the output current of the 1 st contact part 110 in correspondence to the change in the resistance value.
On the other hand, the control unit 200 can detect the resistance value of the closed circuit including the 1 st contact 110 and the 2 nd contact 120 in the operation mode. Similarly to the standby mode, the control unit 200 can sense whether the user's skin is in contact with the 1 st contact part 110 and the 2 nd contact part 120 respectively in the operation mode.
In the operation mode, when it is sensed that the skin of the user is not in contact with at least one of the 1 st contact part 110 and the 2 nd contact part 120, the control part 200 controls the skin management device 1 to the standby mode (34), as shown in fig. 3.
In various embodiments, in the case where the operation mode driving time of the skin management device 1 is set in advance or a user input for setting the operation mode driving time is received through the button part 130, the control part 200 controls the skin management device 1 to the standby mode or to the power-off state after the set operation mode driving time elapses. In one embodiment, the operation mode driving time may be previously set to 3 minutes.
Even when the operation mode driving time is set, the control unit 200 may control the skin management device 1 to the standby mode when it is sensed that the skin of the user is not in contact with at least one of the 1 st contact part 110 and the 2 nd contact part 120 before the operation mode driving time elapses.
As described above, the skin management device 1 according to an embodiment of the present invention automatically switches to the operation mode when the skin of the user is sensed to be in contact with both the 1 st contact part 110 and the 2 nd contact part 120 in the standby mode, thereby improving the convenience of the user's operation, and having the main body 100 with a plurality of buttons, thereby having an effect of preventing the device from being complicated.
On the other hand, in various embodiments, the control portion 200 may control the magnitude of the output current of the 1 st contact portion 110 and the 2 nd contact portion 120, and also control the vibration speed and intensity (tapping speed and intensity) of the vibration portion 112. For example, the control unit 200 may control at least one of the vibration speed and the intensity of the vibration unit 110 in a linear form, a curved form (e.g., sine wave), a stepped form (e.g., square wave), or the like, with time.
In one embodiment, the control portion 200 may sense the pressure applied to the vibration portion 112. More specifically, the control section 200 may sense pressure applied to the vibrator or moving body provided to the vibration section 112. To this end, the skin management device 1 may include at least one resistance circuit, a pressure sensor, and the like, which are connected to the vibration part 112 and the control part 200 and may sense the pressure applied to the vibration part 112.
When determining that the pressure applied to the vibration part 112 is equal to or greater than the preset threshold value, the control part 200 outputs an alarm or the like through an output part (not shown) provided in the skin management device 1 or controls the skin management device 1 to be in a standby mode or an off state. Thus, the skin management device 1 of the present invention can prevent the problem of rapid battery consumption and a reduction in product life caused by an erroneous operation that causes excessive restraint to the vibration portion 112 (motor provided in the vibration portion 112) due to the user strongly adhering the vibration portion 112 to the skin surface.
In various embodiments of the present invention, the control unit 200 may control the skin management device 1 to be turned off while the skin management device 1 is kept in the standby mode for a predetermined time or more.
The storage unit 300 stores programs, data, and the like necessary for the operation of the control unit 200. In various embodiments of the present invention, the storage unit 300 may store information for the 1 st minimum current, the 2 nd minimum current, the output current increase control, information related to the output current corresponding to the resistance value detected at the 1 st contact 110, and the like.
In addition, in various embodiments of the present invention, the storage unit 300 may store information on the operation control of the skin management device 1 corresponding to the user input received through the button unit 130.
Fig. 4 is a sequence diagram showing a control method of the skin management apparatus according to an embodiment of the present invention. The following operation is described based on the operation of controlling other components by the control unit 200 provided in the skin management device 1.
In the starting step of fig. 4, the control unit 200 may be controlled to be on according to a user input for controlling the skin management device 1 to be on through the button unit 130 and then may operate in the standby mode (410).
In the standby mode, the control unit 200 may control the 1 st contact 110 and the 2 nd contact 120 to output a preset 1 st minimum current (411).
The control part 200 may sense whether the skin is in contact with the 1 st contact part 110 and the 2 nd contact part 120, respectively (412).
The control unit 200 may detect a resistance value corresponding to a 1 st minimum current of a closed circuit including the 1 st contact 110 and the 2 nd contact 120, respectively, and sense whether the skin is in contact with the 1 st contact 110 and the 2 nd contact 120, respectively, based on a change in the resistance value.
When it is sensed that the skin is not in contact with at least one of the 1 st contact 110 and the 2 nd contact 120 (412), the control part 200 may continue to control the skin management device 1 to the standby mode.
In various embodiments of the present invention, the control unit 200 may control the skin management device 1 to be turned off while the skin management device 1 is kept in the standby mode for a predetermined time or more.
When the skin is sensed to be in contact with both the 1 st contact part 110 and the 2 nd contact part 120 (412), the control part 200 may control the skin management device 1 to the operation mode (420).
Specifically, the control part 200 may control the 1 st contact part 110 to output a preset 2 nd minimum current (421).
Thereafter, the control unit 200 controls the 1 st contact 110 to increase the output current until the output current of the 1 st contact 110 reaches the determined final output current (422).
The final output current may be determined by user input through the input unit 130 or may be determined according to a preset value.
The control part 200 may increase the output current of the 1 st contact 110 based on the information for the output current increase control until the output current of the 1 st contact 110 reaches the set final output current. Here, the information for the output current increase control may include at least one of an increase shape (linear, curved, or stepped), an increase time (period), an increase speed, and an increase size.
While the skin management device 1 is controlled to the operation mode thereafter, the control unit 200 may detect the resistance value of the 1 st contact unit 110, and control the 1 st contact unit 110 to output a current corresponding to the detected resistance value (423).
On the other hand, the control unit 200 may control the 2 nd contact 120 to output the 2 nd minimum current while the operation mode is being executed.
While the skin management device 1 is controlled to the operation mode, the control unit 200 may sense whether the skin is in contact with the 1 st contact unit 110 and the 2 nd contact unit 120, respectively (424).
When it is sensed that the skin is not in contact with at least one of the 1 st contact 110 and the 2 nd contact 120, the control part 200 may control the skin management device 1 to the standby mode again.
In one embodiment, in the case where the operation mode driving time is set by setting or according to the user input, the control part 200 may control the 1 st contact part 110 and the 2 nd contact part 120 according to the operation mode during the set operation mode driving time, and then control the skin management device 1 to the standby mode again or control the power of the skin management device 1 to be off.
Fig. 4 shows that the output current of the 1 st contact 110 is controlled according to the time sequence in the operation mode and whether the skin is in contact with the 1 st contact 110 and the 2 nd contact 120 is sensed, but in various embodiments of the present invention, the control unit 200 may simultaneously sense whether the skin is in contact with the 1 st contact 110 and the 2 nd contact 120 while controlling the output current of the 1 st contact 110 in the operation mode, and control the skin management device 1 to be in the standby mode and control the 1 st contact 110 and the 2 nd contact 120 to make the 1 st contact 110 and the 2 nd contact 120 output the 1 st minimum current when sensing that the skin is not in contact with at least one of the 1 st contact 110 and the 2 nd contact 120 while controlling the output current of the 1 st contact 110 and the 2 nd contact 120.
The control unit 200 repeatedly executes the above-described operations until a user input for controlling the skin management device 1 to be turned off is received via the input unit 130 (425).
On the other hand, since the user input for controlling the skin management device 1 to be turned off can be received in either one of the standby mode and the operation mode of the skin management device 1, the control unit 200 may control the skin management device 1 to be turned off when the user input for controlling the skin management device 1 to be turned off is received through the input unit 130 instead of being executed in time series with the other operations as shown in fig. 4, as to whether or not the user input for controlling the skin management device 1 to be turned off is received in the standby mode and the operation mode.
The present invention has been described in detail with reference to the specific embodiments, but the present invention is not limited thereto, and it is obvious to those skilled in the art that the present invention can be modified or improved within the technical idea of the present invention.
The present invention relates to the field of the present invention, and more particularly, to a method and apparatus for detecting and correcting the position of a substrate.
