The traditional devices that are in existence are limited in that they utilize and focus upon a connection between the bat and the ball or the bat and another similar object.
These devices are further limited in that they require a striking component, such as a
baseball bat, as known in the art, a
tennis racket, as known in the art, or similar component.
While the traditional related art is effective when focusing on the contact or when using the restraint, it is limited in that there must be some type of contact in the former and a constant restraint in the latter.
Hence there is an embedded requirement of numerous components which are not a worthwhile improvement in simplicity from the usual
baseball bat, as known in the art, coupled with a baseball, as known in the art, that is used in traditional batting practices.
The numerous components in some situations require analysis of the many parts which may not be feasible for young athletes trying to
train with the devices.
This traditional connection between the components is limited based on the contact between the bat and the ball and the ball's interaction with the stop.
These devices are limited in that they require a constant restraint on the athlete or batter and can lead to a dependency upon the device for the proper swing rather than the development of sufficient
muscle memory.
This type of traditional restraint may cause reliance of the batter upon the restraint rather than developing
muscle memory independent of force.
Both features run the risk of the user becoming reliant upon the restraint and audible indicator instead of developing independent
muscle memory.
This
vest and harness comprise complex parts that may lead to reliance upon devices and restraints that will not be available to the batter during the actual competition.
Smull not only requires a restraint to
restrict the top hand from dominating the batting swing, but it also does not provide for any adjustments for the various
age groups that participate in the sports.
While fairly effective in training, the related art is deficient not only in the complexity of the necessary components but also in the lack of versatility in use among the various ages and body types.
This creates a problem since both children and adults have different size necessities.
The safety of the related art is also problematic.
The multitude of various components of hard or resistant material increases the risk of a user being injured by stray parts coming loose during a practice swing.
The complexity and numerousity of the apparatus make it difficult for use by an athlete of any age.
The suspended weight may be unsafe for athletes of young age wishing to improve their swing
mechanics.
Such a device would not be appropriate or safe for persons or athletes of any age.
Not only does Andrews illustrate the problem with the related art of focusing mainly on the contact between the ball and bat, but it also contains various
moving parts which could easily compromise the safety of a swing training device.
The multiplicity of parts increases the chances of unsafe conditions and the inability to adjust the height of the post and swing guide connectors makes use of each apparatus restricted to one size and shape athlete.
As with Laseke, Hardison is not readily adjustable to different sized athletes.
As evidenced above, related art has attempted to create training devices that solidify an athlete's swing, such as in golf, tennis or baseball, but have failed to deal with the problems of complexity, adjustability and safety.
