Description

[Technical field]

[0001] The present invention relates to a smart ring, and more particularly to a manufacturing method for a smart ring that uses a sensor module to measure various body activities and conditions, and a smart ring manufactured thereby. [Background technology]

[0002] As the average life expectancy of modern people increases, they are more interested in their health than ever before. This interest has led to the invention of devices that can continuously manage your health on a daily basis, breaking the stereotype that you should only see a doctor when you are sick.

[0003] Many of the above-mentioned devices, called wearable devices, emphasize portability and can be worn and carried around freely like clothing, watches, or glasses. Examples of such wearable devices include smart glasses, smart watches, and ring-shaped wearable devices.

[0004] Among these, US Patent US9861314B2, which is prior art regarding a ring-shaped wearable device, discloses a wearable electronic device and a manufacturing method thereof.

[0005] This prior art discloses a molded body of a moldable ceramic material including an inner surface, an outer surface, and at least one cavity disposed on the inner surface and having a depth, an electronic component disposed in the cavity and having a thickness smaller than the depth of the cavity, and a method of manufacturing a smart ring, which includes forming a coating of an epoxy material along the inner surface of the smart ring to cover the electronic component and the cavity on the inner surface of the body molded using a prior art molding device and molding method.

[0006] A smart ring manufactured according to the prior art manufacturing method using the above-mentioned prior art molding system embodies a predetermined inner shape and size of the smart ring according to the fixed shape and size of the inner surface of the already molded body.

[0007] As a result, according to the conventional smart ring manufacturing methods, including the conventional manufacturing methods, when it is necessary to change or move the circuit components, form or change the position of a protrusion such as a sensor on the inner surface of the smart ring, or change the shape and size of the inside of the smart ring according to a design intent other than the above, in order to newly mold and produce a body having a different inner shape and size, it is necessary to prepare multiple molding parts such as the mold of the molding device and their settings according to the different inner shape and size. Therefore, the conventional smart ring manufacturing methods, including the conventional manufacturing methods, have a problem of being difficult to meet various requirements regarding the inner shape and size of the smart ring.

[0008] In addition, in order to realize smart rings with inner surfaces of various shapes and sizes using conventional smart ring manufacturing methods, including prior art manufacturing methods, the number of pieces of equipment such as molds and coating devices increases proportionately, and individual setting up of these equipment requires additional time, resulting in the problem of increased time and cost for developing and manufacturing smart rings of various shapes and sizes.

[0009] Furthermore, when molding an epoxy material along the inner surface of a smart ring using a conventional smart ring manufacturing method including a prior art manufacturing method and a molding device used therein, the transparency of the inner surface of the smart ring is determined by the surface condition of the inner surface molding part of the molding device, and there is a limit to how much transparency can be adjusted, so a separate polishing process is required to make the surface of the product beautiful, which leads to problems such as reduced product quality and complicated manufacturing processes, resulting in inefficiencies.

[0010] Furthermore, when molding an epoxy material along the inner surface of a smart ring using the conventional molding device and molding method shown in Figure 11, the area of ​​the epoxy injection part, which acts as an outlet for air bubbles that occur in the injected epoxy, is small, so it takes a long time to remove the air bubbles or they cannot be removed sufficiently, resulting in a decrease in product quality.

Therefore, even without changing the molding equipment, it is possible to realize various inner shapes and sizes of smart rings through the inner molding part processing process, which includes a simple cutting process.

[0037] In addition, the new smart ring manufacturing method of the present invention and the smart ring manufactured thereby make it easy to adjust the transparency of the entire inner surface of the smart ring or only a portion of the inner surface, thereby improving product quality related to transparency and streamlining the production process.

[0038] In some embodiments, by improving the transparency of all or part of the inner surface of the smart ring through surface treatment of the inner surface, such as clear coating, it is possible to precisely process the portions that allow the signals or light necessary for the sensor module to sense the smart user's biosignals to pass through, thereby improving the accuracy of the sensor module's biosignal sensing and streamlining related production processes.

[0067] In this embodiment, the overall outer wall shape of the bracket portion 230 may have a semicircular shape, as shown in FIG.

[0068] The outer cover part and sensor / communication module combination manufacturing process (S200) involves accommodating the sensor / communication module 200 inside the ring shape of the processed outer cover part 100 to form a ring-shaped combination, and in this embodiment, the accommodated sensor / communication module 200 is attached and fixed to the inner wall of the outer cover body 110 via the second mounting member 223 of the mounting part 220 of the sensor / communication module 200.

[0069] The inner molded part processing step (S300) creates an inner molded part 300 having a hole of a preset shape inside the ring-shaped combination body into which the finger of the smart ring user fits.

[0070] The inner molding part processing step (S300) of the present invention is performed in a novel manner in which the entire inner area of ​​the ring-shaped combination of the outer cover part and the sensor / communication module is filled with molding material, and then a hole of a preset shape is cut in the center of the filled molding material to generate the inner molding part 300.

[0071] The inner molding part 300 is manufactured by molding a molding member made of a transparent material, which can produce a coated transparent or translucent part by applying a clear coating to enhance transparency after molding.

[0072] As a transparent molding material, a transparent thermosetting plastic such as a transparent hard epoxy can be used.

[0073] FIG. 5 is a diagram for explaining an embodiment of the inner molded portion processing step (S300) of the present invention.

[0074] Referring to FIG. 5, the inner molding part processing process (S300) of this embodiment includes a molding material injection / curing process in which a molding material is injected into the entire inner area of ​​the ring-shaped combination of the outer cover part and the sensor / communication module using the molding device of the embodiment of the present invention shown in FIGS. 8 to 10, the molding material is cured, and the molding device is removed.

[0075] By carrying out the molding material injection / curing process, a ring-shaped combined sensor / communication module is obtained in which the entire inner region is filled with the hardened molding material, as shown in Figure 5(a), and then a horizontal cutting process is carried out to cut off the molding material protrusions that protrude from one or more of the upper or lower surfaces of the ring-shaped combined sensor / communication module in which the entire inner region is filled with the hardened molding material.

[0076] As a result of carrying out the above horizontal cutting process, a ring-shaped combination of sensor / communication modules is obtained in which the entire inner area free of protrusions is filled with the hardened molding material, as shown in FIG. 5(b).

[0077] A vertical cutting process is then performed to machine a hole of a preset shape in the center of the filled molding material of the ring-shaped combination of the sensor / communication module, whose entire inner area free of protrusions is filled with molding material.

[0078] As a result of carrying out the vertical cutting step, an inner molded part body 310 having an inner vertical surface is formed as shown in FIG. 5(c).

[0079] Then, a rounded portion processing step is performed in which at least one of the upper end portion and the lower end portion of the molded portion body 310 is rounded to form the rounded portion 320.

[0080] As a result of the execution of the rounded portion processing step, an inner molded portion 300 consisting of a molded portion body 310 and a rounded portion 320 as shown in FIG. 5(d) is formed.

[0081] The horizontal cutting process, vertical cutting process, and rounding process can be performed by CNC machining.

[0082] The sensing window forming process (S400) is a process of forming a sensing window, which is a portion that transmits signals or light required for the sensor module to sense the biosignals of the smart ring user, on the inner surface of the inner molding part 300. This is a process of processing all or a part of the inner surface of the inner molding part 300, i.e., the wall surface of the hole created by cutting, so that signals or light can pass through.

[0083] In this embodiment, a clear coating layer is formed on all or part of the inner surface of the inner molding part 300, which is the processed cut surface of the hardened transparent material molding member, to improve transparency, thereby forming a part optimized for the transmission of signals and light, allowing the transmission of signals and light transmitted and received by the sensor module.

[0084] In the present invention, a clear coating with adjusted transparency is applied to all or part of the inner surface of the inner molding part 300, and the position of the sensor module, i.e., if an optical blood flow measurement sensor is included, the position corresponding to the positions of the light emitting part and the light receiving part of the optical blood flow measurement sensor is clear coated, and a transparent or translucent part with high transparency is generated as a sensing window 330.

[0085] In the present invention, the areas to which the clear coating is applied can be adjusted by selectively masking the areas not to be clear coated prior to clear coating, so that the coated transparent or translucent areas can be used to create a sensing window (330) by easily applying clear coating to the desired location and range and increasing transparency.

[0086] In addition, the transparency of the clear-coated portion can be adjusted by adjusting the type and composition ratio of various known clear coating liquids, so that a transparent or translucent sensing window 330 having a transparency optimized for the characteristics of the sensor module can be produced.

[0087] The sensing window formation process (S400) includes a masking process in which a masking member is attached to the portion of the smart ring to be processed that is not to be clear coated, a primer coating process in which a primer coating liquid is applied to the inner surface of the inner molding part 300 to be clear coated to form a primer layer, a process in which a clear coating liquid having an adjusted transparency is applied to the dried primer layer to form a clear coating layer, and a drying and masking removal process in which the clear coating layer is dried and the masking member is removed. The portion to be clear coated can be adjusted by adjusting the range and shape of the masking according to each embodiment.

[0088] FIG. 6 is a diagram for explaining one embodiment of the sensing window forming step (S400) of the present invention, and FIG. 7 is a diagram for explaining another embodiment of the sensing window forming step (S400) of the present invention.

[0089] In the sensing window forming step (S400) of the embodiment of Fig. 6, a clear coating with adjusted transparency is applied to the entire inner surface of the inner molding part 300, and a sensing window 330 is formed, which is a transparent or semi-transparent part that transmits a signal or light required for sensing a biosignal at a position corresponding to the sensor module. In this embodiment, the sensing window 330 of the embodiment of Fig. 2 is formed.

[0090] Referring to FIG. 6, the sensing window formation process (S400) of this embodiment includes a masking process in which a masking member is attached to the outer cover portion, which is the portion of the smart ring to be processed in FIG. 6(a), which is not to be clear coated; a primer coating process in which a primer coating liquid is applied to the entire inner surface of the inner molded part 300 where the clear coating is to be performed, i.e., the surface of the molded part body 310 and the rounded part 320, to form a primer layer; a process in which a clear coating liquid with adjusted transparency is applied to the dried primer layer to form a clear coating layer; and a drying and masking removal process in which the clear coating layer is dried and the masking member is removed.

[0091] As a result, as shown in FIG. 6(e), of the entire inner surface of the inner molding part 300 that has been made transparent or semi-transparent by the clear coating, a portion corresponding to the position of the sensor module is formed as a sensing window 330.

[0092] 7, the sensing window forming process (S400) performs clear coating with controlled transparency only on a portion of the inner molding part 300 corresponding to the position of the sensor module, and forms the sensing window 330, which is a portion that transmits a signal or light required for sensing a biosignal, in the clear-coated portion corresponding to the sensor module. In this embodiment, the sensing window 330 of the embodiment of FIG. 3 is formed.

[0093] Referring to FIG. 7, the sensing window formation process (S400) of this embodiment includes a masking process in which a masking material is attached to the outer cover part and the part of the inner molded part 300 corresponding to the position of the sensor module, which are the parts of the smart ring to be processed in FIG. 7(a), which are not clear coated; a primer coating process in which a primer coating liquid is applied to the surface of the inner molded part 300 where the clear coating is to be performed to form a primer layer; a process in which a clear coating liquid having an adjusted transparency is applied to the dried primer layer to form a clear coating layer; and a drying and masking removal process in which the clear coating layer is dried and the masking material is removed.

[0094] As a result, as shown in FIG. 7( e ), only the portion of the inner molding part 300 that is made transparent or semi-transparent by the clear coating and corresponds to the position of the sensor module is formed as a sensing window 330 .

[0095] In this embodiment, various paints can be used as the primer coating, and in this embodiment, the product names Eureka Primer #152 or UVILUX PRIMER #100-3 (NY) can be used.

[0096] For clear coating, the mixing ratio of the luminous paint and non-luminous paint can be adjusted to adjust the transparency, so that the ratio of luminous paint to non-luminous paint can be 10:0 to make it completely transparent, or the ratio of luminous paint to non-luminous paint can be 5:5 to make it semi-transparent, allowing for the realization of the desired level of transparency.

[0097] In this embodiment, the product HNP-UTT #3003(P) CLEAR, whose main component is acrylic polyol resin, or the product HNP-UVT #6011 CLEAR, whose main component is modified acrylic oligomers, or the product Ubichem CVM890SH Top Coat Oil Light (Improved), whose main component is reactive monomers, can be selectively used as the luminous paint, and the product HNP-UTT #3003(P) MATT, whose main component is acrylic polyol resin, or the product HNP-UTT#3003(P) CLEAR, whose main component is acrylic polyol resin, can be selectively used as the non-luminous paint.

[0098] Prior to the masking process, a static elimination process can be performed to neutralize the static electricity charged on the outer cover part 100 using ions, i.e., to consume the accumulated static electricity using ions, thereby removing foreign matter such as dust from the surface of the outer cover part 100.

In this embodiment, the silicon may have a hardness of 60 to 70 degrees.

[0110] The inner upper frame 430 supports the upper region of the combination of the outer cover part 100 and the sensor / communication module 200, and allows a molding material to be injected into the inside of the outer cover part 100.
