Abstract

Disclosed is a smart ring device including: a sensor, an outer ring, an inner ring disposed inside the outer ring, a printed circuit board disposed between the outer ring and the inner ring, and a first protrusion protruding from one surface of an inner part of the inner ring in a central direction of the smart ring device, the printed circuit board may include a first light receiving element disposed in a first position of the outer ring, and a first light emitting element disposed at a second position of the outer ring, and configured to transmit a first signal of a first frequency band, wherein the first protrusion may include a first part protruding from the first light emitting element in a first direction facing the center of the smart ring device, and a second part connected to the first part, and protruding from the first light receiving element in a second direction facing the center of the smart ring device.

Claims (40)

1 . A smart ring device comprising:

an outer ring;

an inner ring disposed at least partially on an inside of the outer ring and having a center;

a printed circuit board disposed between at least the outer ring and the inner ring; and

a first protrusion protruding from one surface of an inner part of the inner ring in a central direction,

wherein the printed circuit board includes:

a first light receiving element, comprising light receiving circuitry, disposed at a first position of the outer ring, and a first light emitting element, comprising light emitting circuitry, disposed at a second position of the outer ring and configured to transmit a first signal of a first frequency band, and

wherein the first protrusion includes:

a first part protruding from the first light emitting element in a first direction facing the center;

a second part connected to the first part, and protruding from the first light receiving element in a second direction facing the center; and

a partition wall disposed between at least the first part and the second part, the partition wall extending from a bottom surface of the first protrusion to a top surface of the first protrusion that is radially inward of the bottom surface.

2 . The smart ring device of claim 1 , wherein the bottom surface the first protrusion is includes:

a semi-cylindrical bottom surface, and

wherein the semi-cylindrical bottom surface is disposed on one surface of the inner ring.

3 . The smart ring device of claim 1 , wherein at least a portion of an upper end of the first protrusion is flat.

4 . The smart ring device of claim 1 , wherein a maximum protrusion height of the first part and a maximum protrusion height of the second part are different.

5 . The smart ring device of claim 1 , wherein a size of the first part is greater than a size of the second part.

6 . The smart ring device of claim 1 , wherein the first protrusion is integral with the inner ring.

7 . The smart ring device of claim 1 , wherein at least a portion of the first protrusion is injection molded.

8 . The smart ring device of claim 1 , wherein at least a portion of the first protrusion comprises a material having a transparency of 90% or more.

9 . The smart ring device of claim 1 , wherein at least a portion of the first protrusion comprises an elastic material.

10 . The smart ring device of claim 1 , wherein at least a portion of the partition wall comprises an opaque material.

11 . The smart ring device of claim 1 , wherein at least a portion of the partition wall comprises an elastic material.

12 . The smart ring device of claim 1 , wherein the first signal of the first frequency band includes a signal of a wavelength band of a green color.

13 . The smart ring device of claim 1 , further comprising:

a second protrusion protruding from another surface of the inner part of the inner ring in a central direction of the smart ring device.

14 . The smart ring device of claim 13 , wherein the printed circuit board includes:

a second light emitting element comprising light emitting circuitry disposed at a third position of the outer ring, and configured to transmit the first signal of the first frequency band; and

a second light receiving element comprising light receiving circuitry disposed at a fourth position of the outer ring, and configured to receive a signal irradiated from the second light emitting element, and

wherein the second protrusion includes:

a third part protruding from the second light emitting element in a third direction facing the center of the smart ring device; and

a fourth part connected to the third part, and protruding from the second light receiving element in a fourth direction facing the center of the smart ring device.

15 . The smart ring device of claim 13 , further comprising:

a third protrusion protruding from another surface of the inner part of the inner ring in a central direction of the smart ring device, and disposed between the first protrusion and the second protrusion.

16 . The smart ring device of claim 15 , wherein the printed circuit board includes:

a third light emitting element comprising light emitting circuitry disposed at a fifth position of the outer ring, and configured to transmit a second signal of a second frequency band different from the first frequency band, and

wherein the third protrusion protrudes from the third light emitting element in a third direction facing a center of the smart ring device.

17 . The smart ring device of claim 16 , wherein the second signal of the second frequency band includes a signal of a wavelength and of a red color.

18 . The smart ring device of claim 15 , wherein a size of the third protrusion is smaller than a size of the first protrusion.

19 . The smart ring device of claim 15 , wherein the first protrusion and the second protrusion are disposed to be symmetrical to each other with respect to the third protrusion.
