Description

SMART CRICKET BAT AND PROCESS OF FABRICATION OF THE SAME

EARLIEST PRIORITY DATE:

This Application claims priority from a Provisional patent application filed in India having Patent Application No. 201941017797, filed on September 03, 2019, and titled “SMART CRICKET BAT”.

FIELD OF INVENTION

Embodiments of the present disclosure relate to sport accessories, and more particularly to, a smart cricket bat and a process of fabrication of the same.

BACKGROUND

Cricket is a game played with a bat and a ball between two teams. Each team includes eleven players. Cricket is viewed by millions of people around the world. Due to the worldwide popularity the game has gained over the years, many individuals aspire to represent their country and train in that direction. Training involves for instance, attending a cricket camp organized by veteran bowlers and batsmen, often referred to as coaches, having played the game of cricket in different forums and levels. The coaches train individuals to become bowlers or batsmen subsequent to testing the individual’s potential. If the coach ascertains that the individual would be a good fit as a batsman, then appropriate training would be provided in this regard.

The individual would be trained with respect to playing different types of shots, swing movement of the cricket bat, etc and relevant feedback would be provided to the individual regarding the performance. The feedback provided is mainly based on observations by the coach. Now a days, due to many individuals attending cricket camps, the coaches may have to train multiple individuals simultaneously. Therefore, there have been instances of the coach, failing to observe certain parameters which are critical for the batsman, thereby not providing proper feedback to the individual, thereby hampering the individual’s growth as a batsman. The other option would be to attend camps which provide personalized training, which of course would be expensive and not affordable by many. Moreover, even then there are possibilities of human error by the coach. Further, to overcome the aforesaid issues, various solutions have been implemented in the past by coupling sensing mechanisms to the cricket bat, which would provide performance related data with respect to batting. However, such sensing mechanisms being detached from the bat and falling on the stumps due to impact of the ball. Also, such sensing mechanism causes an increase in dimension of the bat which is not allowed as per the Marylebone Cricket Club (MCC) rules. Moreover, such sensing mechanism causes discomfort to the batsman while playing shots.

Hence, there is a need for an improved smart cricket bat and a process of fabrication of the same in order to address the aforementioned issues.
