Golf ball marking system and method
A system and method for analyzing impact of a golf club with a golf ball to assess a golfer's golf club swing, equipment and/or alignment. A pattern is marked on an impact side of a golf ball with transferable ink. A face of a golf club is then aligned with the impact side of the golf ball wherein the pattern is square with the face of the golf club. Subsequently, the golf club is swung, impacting the impact side of the golf ball with the face of the golf club. Upon impact, the pattern marked on the impact side of the golf ball is transferred to the face of the golf club. The transferred pattern on the face of the golf club is then analyzed to assess the golfer's golf club swing, equipment and/or alignment.

BACKGROUND OF THE INVENTIONThe present invention relates to a golf ball marking system and method of use thereof. In particular, the invention relates to a system and method for analyzing the impact between a golf ball and a golf club to assess a user's golf club swing, equipment and/or alignment.
Golf is a unique sport that requires both power and precision, and includes many levels of instruction with strict attention to detail. Indeed, no other recreational sport is dominated by professional teachers and instructors the way that golf is. Golf requires accurate feedback to assess a player's game, and while it is possible to practice various techniques, it is impossible to see if those techniques are being performed properly. Thus, the majority of golfers tend to practice their mistakes. Many training aids and swing aids have been introduced to reinforce golf fundamentals and refinements that will hopefully lead to better play.
A major breakthrough for all golfers is achieving consistent center-face contact between the club head and the ball. A club struck solidly near its center of gravity (CG) generally results in longer and straighter hits. The ball goes farther because the club's moment of inertia (MI), or resistance to twisting, is greatest and delivers more energy to the ball. In addition, a center-struck club generally hits the ball straighter because the middle of the face is more square at impact than the toe or heel area of the club face. Enterprising golfers have long known this and have used different methods and impact marking devices for determining the ideal contact point on the golf club's face.
The ability to determine impact location between the golf ball and the golf club as precisely as possible is becoming more important as the average head size of golf clubs increases. Improved driver technology has allowed designers to create larger models with larger hitting surfaces and “hot spots”. For example, in the 1970s, drivers were constructed out of laminated wood or persimmon, and head size was approximately 150 cubic centimeters (cc). However, today's drivers have become increasingly larger and have an average head size beginning at approximately 300 cc and increasing up to a maximum of 460 cc. Further, today's drivers are constructed of metal such as titanium rather than wood. In general, a driver having a larger face results in a more “forgiving” club, particularly with off-center hits.
With the increased head size of drivers, it has been determined that the geographic center of the driver face may not be the most desirable place to make contact with the golf ball. The center of gravity for large model drivers varies from model to model thereby resulting in different “hot spot” locations for the driver depending upon the model. The “hot spot” location of a driver is the area of impact on the driver face providing maximum driving distance, which may be the geographic center of the face, high and toward the heel of the face, high and toward the toe of the face, high and midway up, at the extreme toe of the face, midway up and toward the toe of the face, high and toward the heel, or toeward. Thus, the location of the center of gravity for drivers has a wide distribution between models. Therefore, the larger the club face, the more critical it is to know the location of its center gravity and “hot spot,” and the more beneficial it is to know where a golfer's impact tendency is in relation to these areas.
Further, modern shafts for golf clubs are made from graphite, which is lighter than steel, and helps the player to generate more club head speed. However, graphite shafts tend to posses a spine where a portion of the shaft, longitudinally, is stiffer along one plane, which results in inconsistencies from shaft to shaft. One concern with shaft inconsistencies is “droop,” which is the amount the shaft flexes at impact along a vertical plane measured in degrees. A player should be fitted to a shaft flex that matches his or her swing speed and tempo, but droop must also be considered. Too much (or not enough) droop at impact effects a golfer's ability to make center-face contact. Thus, the ability to measure and quantify club shaft droop benefits golfers seeking more consistent solid contact with the golf ball.
There is a need for golfers to have the ability to determine precise ball to club face contact such that they may determine the “hot spot” of various driver makes and models, but also determine the ideal shaft combination that consistently squares up their club face impact with the golf ball. However, current impact measuring devices are inaccurate and do not have versatile applicability.
Examples of impact marking devices currently used include masking tape applied to the club face to compare the impact contact with the center of the club, whereby the masking tape records a dimple that approximates where contact has been made. Another example includes a crack-and-peal label that attaches to the club face to record an impact mark that changes in intensity. Other impact marking devices include a removable form of stretched leather, and a reusable liquid crystal pad, that darkens for a few seconds after impact. Both of these tools include pads or patches affixed to the club face to record contact point between the club and the golf ball. Finally, spray powders and paints are used as impact marking devices that spray onto the club face and dry, whereby contact with a golf ball during a swing reveal the contact point between the golf ball and golf club.
All of the current impact marking devices are tools that are applied to the club face to determine the impact location and only give a general idea of impact location. Further, there are several disadvantages to the current impact marking devices that are applied to the club face. First, the existing products are not legal for play in sanctioned events according to the United States Golf Association (USGA). Second, current impact marking devices are messy, for example, tapes will stick to the club face and spray paints and powders will splatter on hands, fingers, and other immediate surroundings. Third, current products are bulky and inconvenient to store because weight and space preclude toting them in a golf bag. Fourth, current products are imprecise because the impact marks are roughly the size of a compressed golf ball which exceeds the center of gravity for most golf clubs. Fifth, the impact marking devices are expensive and often fail to last an extended period of time beyond a practice round. Sixth, the current impact marking devices lack versatility and are typically designed for a specific type of club such as a driver, iron, or putter. Seventh, the current products must be applied to the club face instead of the ball, which can adversely affect the ball flight by imparting inconstant ball spin at impact.
BRIEF SUMMARY OF THE INVENTIONThe present invention is a system and method for analyzing impact of a golf club with a golf ball to assess a golfer's golf club swing, equipment and/or alignment. A pattern is marked on an impact side of a golf ball with transferable ink. Then a face of a golf club is aligned with the impact side of the golf ball wherein the pattern is square with the face of the golf club. Subsequently, the golf club is swung, impacting the impact side of the golf ball with the face of the golf club. Upon impact, the pattern marked on the impact side of the golf ball is transferred to the face of the golf club. The transferred pattern on the face of the golf club is then analyzed to assess the golfer's golf club swing, equipment and/or alignment.
