DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] [Embodiment] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described with reference to the drawings. Various characteristic features shown in the following embodiments can be combined with each other.

[0010] Incidentally, a program for realizing the software appearing in one embodiment may be provided as a non-transitory computer-readable recording medium, or may be provided so as to be downloadable from an external server, or may be provided so that the program is launched on an external computer and its functions are realized on a client terminal (so-called cloud computing).

[0011] In addition, in various information processing according to an embodiment, an input and an output according to the input can be realized. Here, as long as an output is obtained as a result of the input, the form of information referenced in such information processing (hereinafter referred to as reference information) is not limited. The reference information may be, for example, rule-based information such as a database, a lookup table, or a predetermined function (including a judgment formula such as a regression formula constructed by a statistical method), or may be a trained model that has previously trained the correlation between the input and the output, or may be a large-scale language model that can output a desired result by inputting a prompt.

[0012] In one embodiment, the term "unit" may include, for example, a combination of hardware resources implemented by a circuit in the broad sense and software information processing that can be specifically realized by these hardware resources. In one embodiment, various information is handled, and this information is represented by, for example, physical values ​​of signal values ​​representing voltage and current, high and low signal values ​​as a binary bit collection consisting of 0 or 1, or quantum superposition (so-called quantum bits), and communication and calculation can be performed on the circuit in the broad sense.

[0013] Furthermore, a circuit in the broad sense is a circuit realized by at least appropriately combining a circuit, circuitry, a processor, and a memory. The processor may be a general-purpose processor or a dedicated circuit. In other words, it includes an application specific integrated circuit (ASIC), a programmable logic device (e.g., a simple programmable logic device (SPLD), a complex programmable logic device (CPLD), and a field programmable gate array (FPGA)), etc.

[0014] 1. Overview First, an overview of the beauty device 1 according to an embodiment will be described. The beauty device 1 includes an action unit and a light source (for example, a uniform light source 32 described later). The action unit includes a light irradiation surface (for example, a resin film 22 described later) on at least a part thereof. The action unit is configured to act on the skin of a user when the beauty device 1 is used at room temperature (hereinafter referred to as normal use). The light source is configured to emit light so that light is irradiated from the light irradiation surface. In this beauty device 1, the predetermined time from the start of normal use until the average temperature of the light irradiation surface reaches an effective state where it is substantially stable is 120 seconds or less, and the average temperature in the effective state is 30 degrees Celsius or more. According to this aspect, compared to the conventional case where it took a certain amount of time until the effective state where a beauty effect appears, it is possible to quickly realize the effective state, thereby reducing wasted time for the user and improving usability.

[0015] Also, a manufacturing method for manufacturing such a beauty device 1 may be provided. This manufacturing method includes a step of preparing a uniform light source 32 for the beauty device 1 and attaching it to the main body of the beauty device 1 (e.g., embedding it in the resin film 22). According to this embodiment, compared to the conventional method in which it took a certain amount of time until an effective state in which a beauty effect appears was achieved, it is possible to quickly achieve an effective state, thereby reducing wasted time for the user, and it is possible to manufacture a beauty device that can improve usability.

[0016] 2. Specific configuration A specific configuration of the beauty device 1 according to one embodiment will be described below. It should be noted that the specific configuration described below is an example that can be included in the overview of the beauty device 1 described above.

[0017] Fig. 1 is a schematic diagram showing the appearance of a beauty device 1, with Fig. 1A showing the front side of the beauty device 1 and Fig. 1B showing the back side of the wearing unit 2. Fig. 2 shows an example of an aspect in which a user wears the beauty device 1. Fig. 3 is a schematic diagram showing a hardware configuration of a light source unit 3 in the beauty device 1. As shown in Fig. 1, the beauty device 1 includes a wearing unit 2 and a light source unit 3.

[0018] The wearing unit 2 is a part that comes into contact with the user when the user wears the cosmetic device 1. The back side shown in FIG. 1B comes into contact with the user. That is, in one embodiment, the cosmetic device 1 is configured as a wearable device that can be worn on the user's body. According to this aspect, particularly due to the configuration of the action part, it is possible to provide a product that the user can easily use as a wearable device at home or the like. Specifically, the wearing unit 2 includes an adhesive sheet 21 and a resin film 22. Note that the use is not limited to home use, and the device may also be used as a treatment device in a medical clinic.

[0019] The adhesive sheet 21 is a part that can be attached to and detached from the resin film 22, and is preferably implemented so as to be disposable after about several uses. That is, the adhesive sheet 21 is preferably formed so as to conform to the shape of the resin film 22 described later. In one example, the adhesive sheet 21 is configured so as to be separable into an adhesive sheet 21 on the right side in the figure and an adhesive sheet 21 on the left side in the figure. Each adhesive sheet 21 has a crescent shape, a C-shape, or a U-shape, and a ring is formed by combining two adhesive sheets 21. At this time, a space S is formed in the center of the ring, so that at least a part of the resin film 22 described later is exposed. Of course, this is not limited to the example, and the adhesive sheet 21 may be configured as one part. In addition, the material of the adhesive sheet 21 is not particularly limited, and for example, an acrylic adhesive, a silicone adhesive, a polyisobutylene adhesive, a gel adhesive, or the like can be adopted. The adhesive sheet 21 is a sheet-like member having flexibility or flexibility. The adhesive sheet 21 comes into contact with the user, allowing the user to use the cosmetic device 1. In other words, the action part may include an abutment part configured to come into contact with the user's skin, and the light irradiation surface is formed to conform to the shape of the action part. The adhesive sheet 21, which is an example of the abutment part, is configured to come into contact with the user's skin when the cosmetic device 1 is used at room temperature (normal use).

[0020] The resin film 22 is long in the left-right direction of the drawing and has a rounded shape, and is formed in a thin film shape. As described above, the adhesive sheet 21 formed to conform to the shape of the resin film 22 is attached to the resin film 22. Therefore, the resin film 22 has flexibility or flexibility like the adhesive sheet 21, and is configured so that the adhesive sheet 21 can be in contact with the user's skin. A uniform light source 32 described later is embedded inside the resin film 22. The resin film 22 is a transparent member so as to transmit light from the uniform light source 32. For example, silicone elastomer, polyurethane (PU) film, polyvinyl alcohol (PVA), ethylene-vinyl acetate (EVA), cellulose acetate, polyethylene (PE) film, etc. may be used. The shape and aspect are not limited to these, and various shapes are possible according to the wearing site. The adhesive layer 21 may be provided on the entire surface of the resin film 22, or the adhesive layer may be configured to transmit light.

[0021] The light source unit 3 is provided on the front side of the cosmetic device 1, adjacent to the wearing unit 2. The light source unit 3 has a housing 31 and a uniform light source 32. The housing 31 has a substantially rectangular parallelepiped shape and has a power source 4 and a control device 5 therein. The power source 4 is configured to be able to supply power for operating the control device 5. In one embodiment, the cosmetic device 1 is a small, cordless device, and the power source 4 may be configured as a storage battery such as a commercially available dry cell or lithium ion battery. The control device 5 may be a computer including the circuit in the broad sense described above.

[0022] Fig. 4 is a schematic diagram showing an example of a hardware configuration of the control device 5. As shown in Fig. 4, the control device 5 includes a communication unit 51, a storage unit 52, and a processor 53, and these components are connected via a communication bus 50.

[0023] The communication unit 51 may include a high-current interface and a low-current interface. Specifically, the control device 5 is supplied with power from the power source 4 via the communication unit 51. The beauty device 1 operates when power is supplied to the control device 5. The communication unit 51 can execute information communication between the beauty device 1 and an external device. This allows the version of the firmware of the beauty device 1 to be updated and functional cooperation with a user's smartphone or the like to be performed. The storage unit 52 also stores various information defined by the above description. This may be implemented, for example, as a volatile or non-volatile memory that stores various programs related to the beauty device 1 executed by the processor 53 or temporarily required information (arguments, arrays, etc.) related to the program calculation. It may also be a combination of these. The processor 53 processes and controls the overall operation related to the beauty device 1. The processor 53 is, for example, a microcomputer or a CPU (not shown). The processor 53 realizes various functions provided in the beauty device 1 by reading out a predetermined program stored in the storage unit 52.

[0024] The functions executed by the cosmetic device 1 may be automatically selected by the processor 53, or may be turned on / off or selected by the user using a switch (not shown) or the like. The functions executed by the cosmetic device 1 include a function of causing the uniform light source 32 to emit light. In addition, if the cosmetic device 1 further includes a stimulating unit that outputs some kind of stimulus other than the uniform light source 32, the functions may include a function of controlling such a stimulus. In other words, the cosmetic device 1 may further include at least one stimulating unit (not shown). The stimulating unit is configured to provide the user with a stimulus other than light. According to this embodiment, it is possible to provide the user with a cosmetic effect due to a different stimulus in addition to the cosmetic effect due to the irradiation of light, as well as other healthy effects.

[0025] The uniform light source 32 will be described in detail later, and the following will supplement the stimulation by a stimulation unit different from the uniform light source 32. Preferably, the stimulation is physical vibration. Preferably, the stimulation unit includes a heater, and the stimulation is temperature stimulation. Preferably, the stimulation unit includes an electromagnet or a magnet, and the stimulation is magnetic stimulation. Preferably, the stimulation unit includes an ultrasound generating unit, and the stimulation is ultrasonic stimulation. Preferably, the ultrasound generating unit is provided so as to surround the light source. Preferably, the ultrasound generating unit is provided in a rectangular or circular shape so as to surround the light source. Preferably, the stimulation provides the user with at least one beauty effect of whitening, improving skin firmness, penetrating beauty ingredients, promoting blood flow, reducing wrinkles, and improving redness.

[0026] In particular, the stimulation unit may include a conductive portion. That is, the stimulation is a stimulation by passing electricity. According to such an embodiment, it is possible to provide the user with a beauty effect by different stimulation and other healthy effects in addition to the beauty effect by light irradiation. In such a case, the conductive portion may be provided so as to overlap with the uniform light source 32. According to such an embodiment, it is possible to realize both the beauty effect by light irradiation and the beauty effect by passing electricity with a compact configuration. Preferably, the conductive portion is an electrode. Preferably, the conductive portions are provided at positions facing each other with the light source as the center. Preferably, the stimulation is an AC stimulation. Preferably, the AC related to the AC stimulation may be 10 kHz or more and 200 kHz or less, or may be 10 kHz or less. In the case of AC stimulation, it is preferable that the stimulation target site by passing electricity between the pair of electrodes and the light irradiation target site are configured to overlap at least partially. The conductive portions (electrodes) may be configured to be provided at positions facing each other with the light source as the center, and the stimulation target site and the light irradiation target site do not necessarily have to overlap.

[0027] The uniform light source 32 is configured to emit uniform light so that the surface of the resin film 22 functions as a light irradiation surface. In the beauty device 1, the uniform light source 32 is configured to emit light to the user's skin during normal use. The uniform light source 32 may be, for example, an LED array in which light-emitting diodes are arranged in a lattice pattern. The uniform light source 32 may also have a configuration in which light-emitting diodes are arranged on the sides and combined with microlenses to achieve surface emission. It is particularly preferable that the uniform light source 32 is configured of an organic electroluminescence (EL). Furthermore, as an example of an organic electroluminescence (EL), an LED may be adopted for the uniform light source 32.

[0028] For example, uniformity is measured as U={M(E)-m(E)} / Av(E), where M(E) is the maximum value of light irradiance E, m(E) is the minimum value of E, and Av(E) is the average value of E. Preferably, U≦0.2. More preferably, U≦0.1. Even more preferably, U≦0.08. Highly preferably, U≦0.05.

[0029] The irradiation intensity of the light from the uniform light source 32 may be sufficient as long as it is strong enough to obtain a cosmetic effect. For example, the irradiation intensity of the light from the uniform light source 32 is 0.5 to 62 mW / cm 2 More preferably, the irradiation intensity is 11.5 to 62 mW / cm. 2Specifically, for example, the irradiation intensity is 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5, 5.5, 6, 6.5, 7, 7.5, 8, 8.5, 9, 9.5, 10, 10.5, 11, 11.5, 12, 12.5, 13, 13.5, 14, 14.5, 15, 15.5, 16, 16.5, 17, 17.5, 18, 18.5, 19, 19.5, 20, 20.5, 21, 21.5, 22, 22.5, 23, 23.5, 24, 24.5, 25, 25.5, 26, 26.5, 27, 27.5, 28, 28.5, 29, 29.5, 30, 30.5, 31, 31.5 ,32,32.5,33,33.5,34,34.5,35,35.5,36,36.5,37,37.5,38,38.5,39,39.5,40,40.5,41,41.5,42,42.5,43,43.5,44,44.5,45,45.5,46,46.5,47, 47.5,48,48.5,49,49.5,50,50.5,51,51.5,52,52.5,53,53.5,54,54.5,5 5,55.5,56,56.5,57,57.5,58,58.5,59,59.5,60,60.5,61,61.5,62mW / cm 2 and may be within a range between any two of the numerical values ​​exemplified here. According to this embodiment, a preferable cosmetic effect can be achieved.

[0030] As described above, since the uniform light source 32 is embedded in the resin film 22, it is preferable that the uniform light source 32 is formed thin. For example, the thickness of the uniform light source 32 is 1 mm or less, preferably 0.5 mm or less, and more preferably 0.1 mm or less. According to this aspect, a contact portion that contacts the user's skin can be realized with a compact configuration. The uniform light source 32 formed thin in this manner can easily achieve flexibility that easily follows the skin. In addition, since it is compact and not heavy when attached to the skin, it is also suitable for implementation in a mode in which it is worn for a certain period of time or more. Furthermore, although different from one embodiment, it is light for the user even in a configuration in which it is irradiated by hand, and usability is improved.

[0031] The illumination of light from the uniform light source 32 is controlled by the aforementioned processor 53, and may be, for example, continuous illumination, or may be based on a pulse signal having a predetermined period, or may be based on a random signal.

[0032] 3. Rise to a valid state Next, the rise of the cosmetic device 1 to the effective state will be described. FIG. 5 is a graph showing the temperature rise of the light irradiation surface (for example, the surface of the resin film 22 in which the uniform light source 32 is embedded) when the user uses the cosmetic device 1 at room temperature (normal use). The cosmetic device 1 according to one embodiment includes the uniform light source 32, and the temperature of the light irradiation surface rises in response to the irradiation of light by the uniform light source 32. The average temperature in the effective state is 30 degrees Celsius or higher. The average temperature may be 48 degrees Celsius or lower. That is, the average temperature is 30 to 48 degrees Celsius, preferably 30 to 45 degrees Celsius, and more preferably 35 to 45 degrees Celsius. As shown in FIG. 5, it can be confirmed that the cosmetic device 1 rises to the effective state more quickly than the comparative examples A and B.

[0033] The temperature of the light irradiation surface may be, for example, the temperature within a predetermined region included in the light irradiation surface. The shape of the predetermined region is not particularly limited, but may be, for example, a predetermined circle centered on the approximate center of the light irradiation surface. In addition, in a shape in which the center is not clear, such as a ring, an elongated shape, or a deformed shape, the predetermined region may be centered on the center line. The area of ​​the predetermined circle or the predetermined region is preferably 1 to 100% of the area of ​​the light irradiation surface, more preferably 5 to 90%, even more preferably 10 to 80%, and even more preferably 60 to 85%, and specifically, for example, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 4 0, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98, 99, 100%, and may be within a range between any two of the numerical values ​​exemplified here.

[0034] In one example, the uniform light source 32 of the beauty device 1 is an organic electroluminescent device, and the time required to become effective (predetermined time) is 52 seconds. That is, as described in the above overview, the predetermined time is 120 seconds or less, and more preferably, the predetermined time is 60 seconds or less. Specifically, for example, the predetermined time is 120, 115, 110, 105, 100, 95, 90, 85, 80, 75, 70, 65, 60, 55, 50, 45, 40, 35, 30, 25, 20, 15, or 10 seconds, or may be within a range between any two of the numerical values ​​exemplified here. According to such an embodiment, it is possible to further reduce the wasted time for the user, and improve usability.

[0035] On the other hand, in Comparative Example A, it took 218 seconds to reach the effective state, and an LED array having 16 LEDs was used as the light source. Furthermore, in Comparative Example B, a side LED combining an LED and a microlens was used, but it could not reach the effective state. Note that the uniform light source 32 is not limited to the iOLED, and the uniform light source 32 of the beauty device 1 can be realized depending on the number of LEDs or the configuration with the microlens.

[0036] As can be seen from the graph shown in FIG. 5, the average rate of temperature rise of the contact portion from the start of normal use until the effective state is 3 degrees or more per minute. According to such an embodiment, the temperature rise of the contact portion is more specifically defined, which can reduce wasted time for the user and improve usability. The average rate of temperature rise is preferably 4 degrees or more per minute, more preferably 5 degrees or more, and even more preferably 10 degrees or more. The average rate of temperature rise per minute is, for example, 3, 3.2, 3.4, 3.6, 3.8, 4, 4.2, 4.4, 4.6, 4.8, 5, 5.2, 5.4, 5.6, 5.8, 6, 6.2, 6.4, 6.6, 6.8, 7, 7.2, 7.4, 7.6, 7.8, 8, 8.2, 8.4, 8.6, 8.8, 9, 9.2, 9.4, 9.6, 9.8, 1 0, 10.2, 10.4, 10.6, 10.8, 11, 11.2, 11.4, 11.6, 11.8, 12, 12.2, 12.4, 12.6, 12.8, 13, 13.2, 13.4, 13.6, 13.8, 14, 14.2, 14.4, 14.6, 14.8, 15 degrees, and may be within a range between any two of the values ​​exemplified here.

[0037] 4. Temperature variation in the effective state Next, the temperature unevenness in the effective state of the beauty device 1 will be described. Fig. 6 is a thermograph comparing the temperature distribution of the beauty device 1 (Fig. 6A) with that of comparative examples A and B (Figs. 6B and 6C). The beauty device 1 according to one embodiment includes a uniform light source 32, and the temperature of the light irradiation surface increases in response to irradiation of light by the uniform light source 32. The average temperature in the effective state is 30 degrees Celsius or higher. The average temperature may be 48 degrees Celsius or lower. That is, the average temperature is 30 to 48 degrees Celsius, preferably 30 to 45 degrees Celsius, and more preferably 35 to 45 degrees Celsius.

[0038] In one example, an organic electroluminescence (EL) light source 32 of the beauty device 1 is used, and the temperature distribution of the light irradiation surface (for example, the surface of the resin film 22 in which the uniform light source 32 is embedded) inside the circle marked A in the figure for the beauty device 1 is 29.2 to 30.4 degrees Celsius, and the temperature difference is 1.2 degrees. In comparative example A, an LED array having 16 LEDs is used as the light source, and the temperature distribution of the same range for comparative example A is 29.1 to 31.1 degrees Celsius, and the temperature difference is 2 degrees. Furthermore, in comparative example B, a side LED combining an LED and a microlens is used, but it does not reach 30 degrees Celsius in the first place and does not reach an effective state. In comparative example B, the temperature distribution of the same range at the steady state, although not yet reaching an effective state, is 28.0 to 29.3 degrees Celsius, and the temperature difference is 1.3 degrees.

[0039] That is, as explained in the overview, in the beauty device 1, the temperature difference between the maximum temperature and the minimum temperature in the light irradiation surface is less than 2 degrees, and the average temperature in the effective state is 30 degrees Celsius or more. Preferably, in the beauty device 1, the temperature difference in the light irradiation surface is 1.5 degrees or less. More preferably, in the beauty device 1, the temperature difference in the light irradiation surface is 1.2 degrees or less. Specifically, for example, the temperature difference is 2.0, 1.9, 1.8, 1.7, 1.6, 1.5, 1.4, 1.3, 1.2, 1.1, 1, 0.9, 0.8, 0.7, 0.6, 0.5, 0.4, 0.3, 0.2, 0.1, or 0 degrees, and may be within a range between any two of the values ​​exemplified here. According to this embodiment, it is possible to reduce the temperature unevenness in the area of ​​the skin where the beauty device is applied, and thus reduce the unevenness of the beauty effect on the skin.

[0040] [others] The beauty device 1 according to an embodiment may be implemented in the following manner.

[0041] In the embodiment, the beauty device 1 has been described as a wearable device, but the beauty device 1 may be configured as a handheld device that can be held and used by the user. Even in this case, the light of the uniform light source 32 can be used in a manner that allows the light to be irradiated onto the skin by bringing it close to or in contact with the skin. The uniform light source 32 is not limited to being built into the resin film 22, and may be configured to be covered with glass, a diffusion plate, resin, or the like and irradiated onto the skin. The shape of the wearable device is not particularly limited, and may be configured as a band type, a mask type, a glove type, a sock type, or a hat type. Instead of the adhesive sheet 21, the action part may be configured to directly abut the skin, or may be configured to be fixed and used with a band, a mask, a glove, a sock, a hat, or the like using an elastic material such as cloth, silicon, or rubber. In this case, even when the user holds it and uses it, it is preferable that the distance to the skin is close or the action part is in contact with the skin.
