Abstract

A smart ring and a method for manufacturing a smart ring are disclosed. The smart ring of the present invention comprises an outer cover portion (100) having a ring shape and accommodating a sensor/communication module, a sensor/communication module (200) including a sensor module accommodating the outer cover portion (100) and detecting a biosignal of a smart ring user, and an inner surface molding portion (300) having a pre-set shape hole into which a smart ring user's finger is inserted. The outer cover portion (100) and the sensor/communication module (200) are combined to form a ring-shaped outer cover portion and sensor/communication module assembly. The inner surface molding portion (300) is formed by filling the entire inner region of the ring-shaped assembly with a molding member, and then cutting and processing a pre-set shape hole in the center of the filled molding member.

Description

Smart Ring and Manufacturing Method for Smart Ring The present invention relates to a smart ring, and more specifically, to a smart ring that measures various activities or conditions of the body using a sensor module, and a method for manufacturing the smart ring. With the increase in average life expectancy, people in modern society are more interested in their health than ever before. This interest is breaking the stereotype that one should only see a doctor when sick, leading to the invention of devices that enable continuous health management on a daily basis. The aforementioned devices, commonly referred to as wearable devices, are devices that emphasize portability and can be freely worn on the body like clothes, watches, or glasses; such wearable devices include smart glasses, smart watches, and ring-type wearable devices. Among these, regarding ring-type wearable devices, the prior art, U.S. registered patent US9861314B2, discloses "wearable electronic device and method of manufacturing the same." This prior art discloses a moldable ceramic body comprising an inner surface, an outer surface, and at least one cavity having a depth disposed on the inner surface, an electronic component disposed within the cavity and having a thickness smaller than the depth of the cavity, and a method for manufacturing a smart ring by forming a coating of 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 molding device and molding method of the prior art. A smart ring produced according to the manufacturing method of the prior art using the aforementioned conventional molding system realizes 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. Accordingly, when using the structure of a smart ring and the manufacturing method of a smart ring according to the prior art, including the manufacturing method of the prior art, if it is necessary to change or move the position of circuit components, form protrusions such as sensors on the inner surface of the smart ring or change their position, or change the shape and size of the inner side of the smart ring according to other design intentions, it is necessary to prepare multiple molding parts, such as molds for molding devices required for this purpose, and their settings according to different inner shapes and sizes in order to newly mold and manufacture a body having a different inner shape and size. Accordingly, the structure of a smart ring and the manufacturing method of a smart ring according to the prior art, including the manufacturing method of the prior art, have a problem in that it is difficult to meet various requirements regarding the inner shape and size of the smart ring. Furthermore, in order to realize smart rings having inner surfaces of various shapes and sizes using the structure of a smart ring and a smart ring manufacturing method of the prior art, the number of equipment such as molds and coating devices increases proportionally, and additional time is required for their individual configuration, resulting in a problem where the development and production time and costs for smart rings of various shapes and sizes increase. Furthermore, when forming an epoxy mold along the inner surface of a smart ring using a conventional smart ring manufacturing method including the manufacturing method of the prior art 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 portion of the molding device, which limits the control of transparency, and a separate polishing process is required to make the surface of the product aesthetic. Consequently, there are issues such as reduced product quality, a complex production process, and inefficiency. Furthermore, when an epoxy mold is formed along the inner surface of a smart ring using a conventional molding device and molding method as shown in Fig. 11, the area of the epoxy injection part, which typically serves as a discharge port for bubbles generated in the injected epoxy, is small, so it takes a long time to remove the bubbles or it is impossible to remove them sufficiently, resulting in a problem of reduced product quality. FIG. 1 is a perspective view illustrating a smart ring of one embodiment of the present invention. FIG. 2 is a perspective view illustrating a smart ring of another embodiment of the present invention. FIG. 3 is an exploded view of a smart ring of an embodiment of the present invention. FIG. 4 is a flowchart of a method for manufacturing a smart ring according to an embodiment of the present invention. FIG. 5 is a drawing for explaining an embodiment of the inner molding part processing process (S300) of the present invention. FIG. 7 is a drawing for explaining one embodiment of the clear coating proc
