Description

CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application is based on and claims the benefit of priority from Korean Patent Application No.: 10-2024-0098142, filed on Jul. 24, 2024, the entirety of which is incorporated by reference herein.TECHNICAL FIELD

[0002] The present disclosure relates to a golf ball and a system for providing ball flight information for golf swings using the smart golf ball. The present disclosure relates to a smart golf ball that not only can maximize the efficiency of putting practice, but also makes it possible to correct a golf swing form, particularly, a golf putting form of a user in more detail by obtaining putting ball flight information including the hit point, the speed, the amount of rotation, the amount of slip, the trajectory, the travel distance, and the spacing angle of a golf ball in putting and by providing the information through a user terminal, and relates to a system for providing ball flight information for golf swings using the smart golf ball.BACKGROUND ART

[0003] In general, putting in golf refers to the action of hitting a golf ball with a putter on a green to put the ball into a hole cup. A golfer, for putting, positions the head of a putter on a golf ball with the grip of the putter in his or her hands, sets the direction in which the golf ball will roll in consideration of the slope of a green, the direction of a hole cup, etc., and the hits the golf ball with the head to put the golf ball into the hole on the green.

[0004] However, most amateur golfers increase the number of strokes in putting due to their inability to putt accurately, and since it is possible to reduce the number of strokes through putting, putting is considered even more important than driving.

[0005] Due to these reasons, significant effort is being allocated to putting practice in golf training, and various aids have been suggested to support putting practice more efficiently.

[0006] For example, in Korean Patent No. 10-1644502, there has been disclosed a golf ball including: a sensor module that is composed of a gyroscope sensor, an acceleration sensor, a power, a transmission chip receiving signals received from the gyroscope sensor and the acceleration sensor and transmitting the signal to a smartphone, and an electronic circuit, and that is positioned at the center of the golf ball; a buffer that covers the sensor module and is made of silicone; a capsule that covers the buffer and is made of carbon fiber reinforced plastic; a core that covers the capsule and is made of soft carbonized cork; a mantle that covers the core and is made of a long fiber reinforced thermoplastic composite containing carbon fibers; a cover that covers the mantle and is made of soft urethane; and a wire that is connected to the transmission chip and extends outward from the center and an antenna that is installed on the bottom of the cover and connected to the wire in order to smoothly transmit a signal from the transmission chip positioned at the center of the golf ball to the smartphone positioned outside the golf ball.

[0007] However, according to the prior art document described above, since the antenna is configured to be inserted in the cover that corresponds to the outer shell of the golf ball, there was a problem in that the golf ball is unavoidably very vulnerable to external impacts.

[0008] Further, according to the prior art document described above, since the buffer and the capsule, and the capsule and the core are configured in a simple bonding method, when the ball is hit by a force over a predetermined level, gaps are formed between the components of the golf ball, whereby the hit direction of the golf ball is determined regardless of the swing posture of a golfer due to the gaps formed in the golf ball when the golf ball is hit. Accordingly, there was a problem in that it was impossible to provide reliable data on the direction and force of hitting of the golf ball.

[0009] Accordingly, the applicant(s) has filed and registered a system for providing smart golf ball trajectory information, the system can improve efficiency of putting practice by creating and providing trajectory information of a hit golf ball, as in Korean Patent No. 10-2685033. However, in this case as well, since multiple pressure sensors are formed only on a predetermined surface, there is a problem in that if impact is not accurately applied to the portion where the pressure sensors are positioned when hitting the golf ball, it is difficult to provide precise data on the trajectory information of the hit golf ball.

[0010] The background art or the related art described above is intended only to help understand the technical significance of the present disclosure and does not describe technologies generally known in the art before filing of this application.PRIOR ART DOCUMENTPatent Document
