The invention generally relates to systems and methods for fitting golf clubs.
Golfers face an overwhelming array of club choices. However, according to Rule 4-4 of The United States Golf Association (Far Hills, N.J.), a player may use no more than 14 clubs in a round of golf. Most golfers understand that a putter is good for short shots on the green and a driver is good for long-distance drives on the order of 200 yards. Between those extremes, golfers would like to find 12 clubs that are each good for shots of a certain distance range and in which those ranges cover all possible shots the golfer may have to make.
Unfortunately, the hundreds of clubs available in a typical shop do not make choosing a set very easy. A golfer must rely on their understanding of how all of those clubs work as well as their estimation of their own abilities to winnow all of the offerings down to the 14 clubs that he will use.
The invention provides systems and methods for selecting a customized golf club set from among many golf clubs. A golfer can give some information about his abilities or existing club set. Systems of the invention work with that information to identify a yardage gap to be covered by clubs and a number of clubs to span that yardage gap. The system can determine one or more yardage for each club and then propose a specific club for each yardage. The system can make use of communication networks to receive new information about clubs that are available, to store or transfer a golfer's personal information (e.g., average driver distance), or to allow a golfer to shop for clubs. Since the system can calculate yardages by which a number of clubs are spread across a yardage gap, the golfer is provided with a proposed set of clubs that is truly personalized and the golfer does not need to settle for one pre-selected set of clubs from a table of only a limited number of sets. Additionally, a golfer can manipulate variables that affect the performance or price of the set and see proposed sets, try new variable values, and compare newly-proposed sets to the first-proposed set. For example, a golfer could toggle a button that allows mixing of clubs from different product lines. Further, systems and methods of the invention allow for functionality not otherwise provided. For example, a golfer can input his real-world playing information and arrive at an optimized set. The golfer could optionally also find a second-best set and, using a device of the invention, could see a price for each set. The golfer could use the device of the invention to purchase one of the sets, to save one of the sets into a wish-list, or both. More exemplary functionality is discussed herein.
In certain aspects, the invention provides a device for fitting golf clubs. The device includes a memory coupled to a processor operable to cause the device to receive a range of distances, obtain a number N of clubs to be suggested, determine a set of distances distributed across the range, and suggest a club for each target distance. In some embodiments, the device determines a set of N distances. The device may determine a set of (N+1) distances, and the device may be further operable to identify an adjustable club that is suited for two of the distances within the set and suggest the adjustable club for the two of the distances. The range of distances may be received as a longest playable iron distance and a driver distance. The longest playable iron distance and the driver distance may be input by a user or received via an interaction between the device and RFID tags on the driver and the longest playable iron. In some embodiments, the device is further operable to obtain the number N based on a user's input of a longest playable iron NL and a number of wedges NW.
The device may be operable to calculate N as 12−NW−(10−NL) and calculate a gap by G=(DD−DI)/(N+1) such that each distance in the set of distances is separated by the gap. In certain embodiments, the set comprises N distances, and the device is further operable to determine an alternative set of (N+1) distances distributed across the range and identify an adjustable club that is suited for two of the distances within the alternative set. The device may be operable to identify an adjustable club that is suited for two of the distances within the set and suggest the adjustable club for the two of the distances. Additionally or alternatively, the device may send an identity of each suggested club to a server computer device, display an offer of at least one of the suggested clubs for a user to purchase, or both.
In certain aspects, the invention provides a method of fitting golf clubs. The method includes receiving—in an electronic device comprising a memory coupled to a processor—a range of distances, obtaining a number N of clubs to be suggested, determining a set of distances distributed across the range, and suggesting a club for each target distance. Preferably, the set comprises N distances. In certain embodiments, the set comprises (N+1) distances, and the method further includes identifying an adjustable club that is suited for two of the distances within the set and suggesting the adjustable club for the two of the distances.
In certain aspects, the invention provides a process for fitting golf clubs. The process includes downloading, using a device comprising a memory coupled to a processor, a set of computer program instructions. The instructions are executable by the processor to cause the device to receive a range of distances, obtain a number N of clubs to be suggested, determine a set of distances distributed across the range, and suggest a club for each target distance. The process further includes storing the set of instructions in the memory and executing the instructions to aid in fitting golf clubs. The instructions may be offered in the form of a mobile app (i.e., that can be downloaded from an app store and executed on an operating system such as Windows 8, Android, or mac OS).

The invention provides systems and methods by which a golfer may select an optimum club set for their playing style. In particular, systems and methods of the invention aid a golfer in selecting clubs to fill the distance gap between their longest iron and driver. Systems and methods of the invention may be used to calculate yardages to fill the gap between a golfer's longest playable iron distance and driver distance and also to make club and adjustment setting recommendation that will enable the golfer to hit those calculated yardages.
Where a golfer desires a club selection optimized for a range of distances, systems and methods of the invention are operable to receive input and aid in composing a proposed set of clubs.
Device 105 is operable to receive input from a user. The input may include information about golf clubs or a golfer's ability or preferences with clubs. As shown in
In certain embodiments, devices and methods of the invention include additional functionality to complement the function of fitting and recommending golf club sets. For example, one or more golfers can collect information about their game as they play, and can compare shots, clubs, results, times, etc., to one another using one or more of device 105. In some embodiments, two (or more) golfers who are playing each use of one device 105 and each input information about clubs that they are using (see
One step of the method is to obtain 205 a number N of clubs to be suggested. In some embodiments, the number N is obtained based on the received a user's input of a longest playable iron and a number of wedges. As shown in
Device 105, by receiving DI—the distance the golfer hits the longest playable iron and DD—the distance the golfer hits his driver—thus receives 201 a range of distances.
The number N of clubs to be suggested can be obtained 205 by performing calculations using the input. In some embodiments, N is calculated by Equation 1.
N=12−NW−(10−NL) Equation 1
Once the golfer has entered this information, a method can proceed by calculating how many clubs can be “fit” in between the golfer's longest playable iron and driver with Equation 1
For example, where a golfer inputs that his longest iron is a 4 iron and he plays 3 wedges:
N=12−3−(10−4)
N=9−6
N=3
In some embodiments, as illustrated by Equation 1, methods of the invention operate with the assumptions that the golfer is playing with 14 clubs; the golfer is playing with 1 putter; and the golfer does not skip an iron throughout his set (e.g. 4, 5, 7, 8, 9, PW).
Once N has been obtained 205, the next step is to determine 207 a set of distances for which the golfer needs clubs. In some embodiments, this set is based on the received range and the obtained N. That is, using N (i.e., how many clubs can be “fit” in between the golfer's longest playable iron and driver), a yardage range can be calculated. The set of distances that is determined 207 can each be separated by this yardage range. This will help ensure equal gaps. The consistent yardage gap may be calculated using Equation 2.
Gap=(DD−DI)/(N+1) Equation 2
where Gap=the gap that each “fit” club must span; DD=Driver distance; DI=Longest Playable Iron distance; and N=number of “fit” long game clubs. Thus, the method involves determining a set of distances that span the range. Moreover, calculation can proceed such that each distance in the set of distances is separated by the Gap. For example, a golfer may input: longest iron is a 4 iron; plays 3 wedges; hits driver 265 yards; and hits 4 iron 195 yards. From this information, a Gap can be calculated.
Gap=(265−195)/(3+1)
Gap=70/4
Gap=17.5 yards
These calculations determine an equivalent gap to be spanned by each of the N “fit” clubs.
Then, a set of distances Di is determined 207. In some embodiments, the set is determined as a set of yardage gap increments above the longest playable iron distance DI. That is, the yardage for the ith “fit” club (for each i={1 . . . N}) may be calculated by Equation 3.
D
i
=D
I
+i×Gap Equation 3
where Di=distance of the ith “fitted” clubs. For example, a golfer inputs that his longest iron is a 4 iron and he plays 3 wedges. The golfer hits his driver 265 yards and he hits his 4 iron 195 yards. As the exemplary calculations above show, this golfer has an N of 3. As the following calculations show, this golfer has a Gap of 17.5.
Gap=(265−195)/(3+1)=17.5
D
1=195+1×17.5
D
2=195+2×17.5
D
3=195+3×17.5
Accordingly, the method determines 207 a set of distances distributed across this golfer's range. Here, the three distances are D1=212.5; D2=230; and D3=247.5. Thus, proceeding by the method, it has been calculated that the golfer needs 3 clubs to be “fit” in between his longest playable iron and driver. The method has also been used to calculate a distance for each of the “fit” clubs such that the golfer will experience equal yardage gaps between all of his long game clubs.
For each determined distance, a club can then be suggested 209. That is, the method includes making a club recommendation, as well as optionally a setting recommendation, for each of the calculated distances above (e.g., D1, D2, . . . , DN).
In some embodiments, the method includes using the availability of a dual-distance club to suggest a set of N clubs for a set of (N+1) distances. A dual-distance club may be taken to refer to a club that is suited to hit to at least two distances. For example, an adjustable-loft club may be useful by a golfer to hit to a number (e.g., two, three, four, five, etc.) of different distances when set in different effective settings. Device 105 may have stored therein information about a club that is suited for hitting to two or more different distances. Recommending clubs can include recognizing the availability of dual-distance clubs and including such a club in the suggested set as being suited for two or more of the distances.
Additionally, methods of the invention may include recommending a first set and an alternative set. For example, the alternative set may include a dual-distance club and may be presented as suited for a greater number of distances than the first set. The invention creates the ability to recognize that the availability of a multi-distance club creates options for a golfer in the form of various club sets. Some golfers may be at a stage in their learning for which a first set of clubs is most beneficially suited to their playing style while other golfers may be best-served by an alternative set. Thus where modern club technology makes available a great variety of potential sets, a golfer may use methods and devices of the invention to select the set best-suited to his or her playing style. Additionally, methods of the invention can employ further information about a golfer to recommend a set. For example, a golfer may provide information that he or she prefers to include or not to include a multi-distance club in the sets that are suggested 209 (e.g., based on personal experience of what works best for that golfer).
Additionally, systems and methods of the invention provide the ability to store 155 information about a golfer or to offer suggested sets to a golfer. For example, as diagrammed in
Use of a system of the invention including, for example, server 133 may provide additional value and benefit due to the ongoing development of technology for golf clubs. A golfer may use device 105. Later, a new golf club could be introduced. Information about the new golf club could be made available through server 133 and that new club could be included in suggestions considered by device 105. Even where a new golf club is a multi-distance or adjustable club, the full potential utility of that adjustable club may be represented within the system and included in the determinations and suggestions of methods of the invention.
Here, adjustable club head 111 is well suited to cover two or more distances in a golfer's yardage range due to the inclusion of a sole-stabilizing element 115. Inclusion of a sole-stabilizing element 115 of a limited width (W) tends to confine the point at which the club head 111 makes contact with the ground to within the limited width. The ground contact point is substantially beneath the club head center of gravity. Since club head 111 rests on a point substantially beneath its center of gravity, it does not tend to rock into a tilted position. Where club head 111 includes a mechanism 121 for adjusting loft, sole stabilizing element 115 can prevent loft adjustments from interfering with face angle. A club head with a sole stabilizing element is described in U.S. Pub. 2013/0225317 to Clausen, et al., the contents of which are incorporated by reference in their entirety for all purposes.
A given adjustment mechanism 121 may be variously mated with different club heads or shafts. For example, if the loft setting shown in window 119 in
For example, a golfer faced with a six-setting adjustable loft mechanism 121 capable of being mated with a mainline men's club head, a mainline women's club head, a Pro men's, and a Pro women's, could potentially be faced with 24 different actual effective loft settings. Additionally, many of these 24 settings may be un-knowable to a golfer. A golfer on the course may not be able to surmise what loft will be provided if they mate an adjustable hosel sleeve to a women's Pro model, for example, nor what distance that club will be best-suited to shoot. Accordingly, device of the invention provide the ability to recommend clubs, combinations of club parts, settings for adjustment mechanisms, or combinations thereof where adjustable or multi-distance clubs are involved. In some embodiments, information about an adjustable club is stored with a device 105, server 133, or both in the form of a look-up table.
One consequence of the availability of a multi-setting club is that it decreases the amount of distance that must be covered by each club. That is, since most golfers will want a total of 14 clubs, having a club that can cover two distances will allow those 14 clubs to cover a total of 15 distances. Thus, the average yardage of the driver, which defines the full range that must be covered, can be divided into 15 gap distances.
Whether or not any number of multi-distance clubs are available, device 105 can be used to make a club and a setting recommendation for each of the calculated distances above (e.g., D1, D2, . . . , DN).
Note that in
Device 105 may perform additional functions as well as fitting sets of golf clubs. For example, device 105 may recommend individual or fit individual clubs. A player may give input identifying a particular make, model, style or type of club. Device 105 can work with information about the player (e.g., driver distance, average ball speed) and recommend fitting settings for the particular club. For example, a player may input that they have a certain hybrid with a 41 inch shaft. The player may input their driver distance, and device 105 may recommend that the player use a 39 inch shaft with their hybrid. Device 105 may include functionality for prompting for, and receiving, information about a player such as: height, gender, handed-ness, geographical location, preferred make or models, type of golf bag, or any other information. Fitting of golf clubs is discussed in U.S. Pat. No. 6,719,648 to Smith; U.S. Pat. No. 6,083,123 to Wood; U.S. Pat. No. 5,441,256 to Smith; U.S. Pat. No. 5,351,952 to Hackman; U.S. Pub. 2011/0207560 to Wright; U.S. Pub. 2004/0087384 to Sosin; and U.S. Pub. 2003/0008731 to Anderson, the contents of each of which are incorporated by reference.
In some embodiments, device 105 includes functionality to allow a golfer to “live chat” with a golf pro. For example, a golfer on the course may feel very frustrated about a tendency to slice. The golfer may execute a program on device 105 and open up a chat window. A corresponding chat window can open on a PC computer at the geographical location of a golf pro consultant. The golfer and the pro can chat and the pro can give personalized recommendations for improving the golfer's game. For example, the pro can recommend, via chat, certain club fits, clubs, settings, or behavior changes that may benefit the player. Chat can be taken to mean a two-way text-based conversation accomplished by entering text into a computer via keyboard, touch-screen, number pad, or similar. Chat may be accomplished via a commercial service such as that offered under the trademark GOOGLE CHAT by Google Inc. (Menlo Park, Calif.). Chat may be accomplished by text or SMS. In a preferred embodiment, chat is provided by a module of functionality integrated into the interface of the fitting app discussed herein. Live chat consultation provides a benefit particularly well-suited to golfers in the context of a mobile app on device 105 as golf is a sport characterized by the promise of serenity but the reality of intense frustration. When frustration threatens to mount, the availability of human consultation integrated into an automatic club suggestion application provides good results for improving player mind-set and thus performance.
In some embodiments, devices and methods of the invention include the ability to assign a yardage to a given club for a particular golfer. As shown, for example, in
Extensive testing has been done to discover a distance range for each of numerous clubs and settings. At least 30 total adjustable club settings for five particular clubs (each either a fairway or hybrid) that each have a six-setting loft-adjustment mechanism have been tested. For each of those 30 total settings, a distance range was discovered for each of a plurality of speed buckets.
Any number of speed buckets may be used. If 2 speed buckets are used, 60 distance ranges are calculated (for a pool of clubs that offer 30 total club settings). If 5 speed buckets are used, 150 distance ranges are calculated. If 25 speed buckets are used, 750 distance ranges are calculated. The number of calculated distance ranges may be a product of the number of total adjustable club settings and the number of speed buckets used. The number of calculated distance ranges can be stored in, for example, a static table on a computer memory such as a hard disk. It has been determined by the inventors that speed buckets are a reliable and useful way to quantize the possible ranges of distances for each club and setting.
With the driver and longest playable iron distances that the golfer provided, device 105 can categorize the golfer into one of the speed buckets. The system can then search the table under the golfer's “speed bucket” for the best club (and effective setting) to be used by the golfer to hit each of the calculated distances from above. Once device 105 has extracted a club and effective setting for each of the calculated distances it may provide all of the results, e.g., on a simple results display. Thus, in some embodiments, methods of the invention include assign a golfer to a speed bucket based on information about the golfer. The information may include DD the distance the golfer hits his driver (DD). A speed bucket may include a set including a characteristic distance for each club, setting, or both for a set of know clubs, settings, or both. In certain embodiments, device 105 has information comprising speed buckets stored therein.
In certain embodiments, functions of the invention are performed by an app. An app can be taken to refer to a program such as one that is downloadable from an app store and executable on a mobile device or with an operating system.
In some embodiments, devices or methods of the invention obtain data about a golfer, that golfer's clubs, distances hit with those clubs, or other information. That information can be input by the golfer (e.g., from knowledge), or may be captured using an information capture mechanism, such as a golf club with data collection capabilities.
A golfer may use the depicted system for providing information. For example, a golfer may tell device 105 that “This club is my driver” (e.g., pressing a button on display 125 while device 105 is reading tag 175. Device 105 may hold information in a memory buffer that the golfer is presently using his driver. Device 105 may capture an initial position using its internal GPS mechanism. The golfer may drive the golf ball and then travel to where the ball has stopped. The golfer may then indicate to device 105 that device 105 is then at the location at which the golf ball has stopped. Device 105 may then capture a stop position using its internal GPS mechanism. Device 105 may then calculate the golfer's driver distance as the difference between the initial position and the stopped position. Additionally, by iterating these steps for different clubs, a golfer could provide information about their distance for each club.
