Description

Technical Field

[0001] This invention belongs to the field of golf club head customization technology, specifically referring to a method for obtaining customized products by memorizing golf club head parameters. Background Technology

[0002] With the current technological advancements, the design and manufacturing processes of golf clubs are becoming increasingly complex. At the same time, players' demands for accuracy, distance, and feel are constantly rising. Traditional golf clubs often use fixed specifications, and their weight distribution, center of gravity, and clubface elasticity parameters are usually not adjustable, making it difficult to adapt to the swing habits and technical preferences of different athletes. Although products that can change club properties by changing weights or adjusting the shaft have appeared on the market, players often need to try them out multiple times or change equipment repeatedly, making it difficult to achieve a clubhead setting that perfectly matches their own swing habits. This results in low customization efficiency and a lack of consistency in the player's user experience.

[0003] From the perspective of current technology, the main challenges are that existing data collection methods lack multi-dimensional real-time monitoring capabilities, making it difficult to effectively quantify the relationship between user hitting characteristics and clubhead response; customized design relies heavily on human experience, making it difficult to establish a mathematical model between the individual and the clubhead; and products manufactured using traditional processes lack optimization space, as adjustments cannot be made after product molding. These challenges result in insufficient user hitting performance and sports experience, thus necessitating the use of innovative technologies to overcome current technological bottlenecks. Summary of the Invention

[0004] In response to the above situation and to overcome the shortcomings of the existing technology, this invention provides a method for obtaining customized products by memorizing golf club head parameters, which effectively solves the problems of traditional golf club head customization products on the market relying on manual experience and lacking adaptability.

[0005] The technical solution adopted by this invention is as follows: This invention proposes a method for obtaining customized products by memorizing golf club head parameters, including the following:

[0006] (a) Data collection phase: Provide adjustable parameter test rod head assembly for users to test, and collect user usage data for different parameter combinations in real time;

[0007] (b) Analysis phase: The collected usage data is transmitted to the data processing system, and the user's personalized parameter preferences are extracted through the big data analysis engine;

[0008] (c) Generation phase: Based on the analyzed parameter preferences, automatically generate a customized 3D design model of the club head that matches the user's biomechanical characteristics.

[0009] Furthermore, the test rod head assembly includes a replaceable screw counterweight module, which dynamically adjusts the position of the rod head's center of gravity by adjusting the weight distribution of the screws.

[0010] Furthermore, the test clubhead assembly includes a multi-specification accessory A, which has variable base angle, loft angle, and base thickness parameters.

[0011] Furthermore, the test clubhead assembly includes a multi-material component B, which achieves gradient adjustment of the overall weight of the clubhead through a combination of materials with different densities.

[0012] Furthermore, the big data analysis in (b) includes:

[0013] Establish a correlation matrix between clubhead center of gravity position, loft parameters, and overall weight; identify user parameter selection patterns through cluster analysis; and extract the parameter threshold combinations corresponding to the optimal shot performance.

[0014] Furthermore, step (c) is implemented using computer-aided design software, which receives parameter instructions from the analysis system, automatically calculates the spatial coordinates of the clubhead's center of gravity, and generates a clubhead structural model that conforms to the USGA standard.

[0015] Furthermore, the computer-aided design software automatically associates the following relationships when performing parametric modeling:

[0016] The geometric correspondence between the position of the counterweight screw and the projection of the center of gravity; the functional relationship between the inclination angle of the rod surface and the height of the center of gravity; the matching relationship between the material density distribution and the moment of inertia.

[0017] Furthermore, after step (c) is completed, a 3D printing data package for the club head and a CNC machining path file are generated to drive additive manufacturing equipment or a five-axis machining center to produce a solid club head.

[0018] Furthermore, the acquisition phase continuously acquires long-term user data to form a dynamic parameter memory library, which triggers iterative updates to the design model when the user's ball-hitting characteristics change.

[0019] Furthermore, the personalized parameter preferences include the following associated parameter groups:

[0020] The mapping relationship between swing speed and optimal clubhead weight; the correction relationship between impact angle deviation and center of gravity shift; and the matching parameters between clubhead moment of inertia and the user's swing plane.

[0021] The beneficial effects achieved by the present invention using the above structure are as follows:

[0022] This solution proposes a method for obtaining customized products by memorizing golf clubhead parameters. This method uses a multi-dimensional parameter acquisition mechanism of adjustable test clubheads to transform the user's hitting experience into objective quantitative data. By utilizing a replaceable weight system, multi-specification structural components, and differentiated materials, it can capture the user's biomechanical feedback on different center of gravity distributions, loft combinations, and weight configurations in a timely manner, and construct core parameters that match the user's swing habits. This process can reduce the deviation of traditional customization that relies on experience estimation and ensure that the design parameters correspond to the user's actual hitting needs.

[0023] The collected data is analyzed using big data to perform multi-parameter modeling. A computer-aided design system is then used to perform parametric modeling. Based on the user's specific center of gravity coordinates, moment of inertia, and other key indicators, the system generates a clubhead structure model that conforms to ergonomic principles. This process transforms traditional manual drawing into an intelligent calculation process, improving design accuracy and efficiency. At the same time, it ensures that the clubhead performance parameters are deeply matched with the user's swing dynamics, solving the problem of insufficient adaptability between standardized products and individuals.

[0024] By tracking user data over a long period and establishing dynamic parameters, the system can continuously perceive the changing trends in a user's hitting ability. When changes in swing characteristics or swing fluctuations are detected, an iterative optimization mechanism for the clubhead structure is automatically triggered. This method enables customized products to have adaptive evolution capabilities, meet current user needs, respond to equipment upgrade demands brought about by technological advancements, and break through the limitations of static design in traditional customized products.

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0030] Example 1

[0031] A method for obtaining customized products by memorizing golf club head parameters

[0032] It offers an adjustable test clubhead with six M4 threaded weight holes on the bottom and five sets of 316L stainless steel weight screws with weight gradients of 1.5g, 2g, 2.5g, 3g, and 4g, for a total adjustment range of 35g. It comes with three interchangeable loft accessories: 55°, 57.5°, and 60° loft angles, with bottom thicknesses of 2mm, 2.3mm, and 2.6mm respectively. During user test shots, the clubhead's built-in triaxial accelerometer records the swing plane angle at a 2000Hz sampling rate, simultaneously triggering a 1000fps high-speed camera to capture clubface deflection data at impact. The collected data generates a parameter set including a 3.5mm center of gravity offset, a 0.8° dynamic loft deviation, and 28 effective weight combinations.

[0033] During the data analysis phase, 20 effective shot data points within the swing speed range of 42-45m / s were selected, and a regression model of the center of gravity coordinates and initial velocity of the shot was established. When the optimal shot performance was identified, corresponding to center of gravity coordinates X=31.2mm, Y=7.8mm, Z=17.5mm and a total weight of 292g, the NX1926 software was driven to perform parametric modeling: using titanium alloy TC4 as the base material, constraining the loft angle to 57.2°, and automatically optimizing the bottom thickness to 2.25mm, a model was generated.

[0034] The manufacturing stage adopts five-axis linkage machining with a spindle speed of 15,000 rpm, a feed rate of 2.8 m / min, and a milling allowance of 0.15 mm. The dynamic optimization mechanism is set to automatically shift the center of gravity towards the toe of the club after accumulating 250 hits or after more than 90 days of use. If the average swing speed is detected to increase to 46.5 m / s, the system will automatically adjust the position of the two 2g screws to adapt.

[0035] like Figure 1 , Figure 2 , Figure 3As shown, traditional mass-produced clubheads often result in a swing deviation of >10% at medium swing speeds due to their fixed center of gravity position. This solution utilizes a 2000Hz three-axis sensor and a 1000fps vision system to control the center of gravity offset within 3.5mm, significantly improving clubface accuracy at medium swing speeds. Based on a customized model with a total weight of 292g and a center of gravity coordinate of 31.2mm, combined with 0.15mm milling allowance control in five-axis machining, it reduces energy transfer loss caused by the mismatch between the clubhead's moment of inertia (MOI) and the user's swing speed. Actual measurements show a reduction in initial velocity fluctuations, effectively solving the problem of large deviations when hitting at medium swing speeds among general golf enthusiasts.

[0036] Example 2

[0037] A method for obtaining customized products by memorizing golf club head parameters

[0038] It offers an adjustable test rod head with 10 M5 threaded counterweight holes on the bottom and 8 sets of tungsten-nickel alloy counterweight screws with mass gradients of 3g, 4g, 5g, 6g, 7g, 8g, 9g, and 10g, for a total adjustment range of 108g. It comes with 5 interchangeable base angle accessories: rod face tilt angles of 53.5°, 55.5°, 57.5°, 59.5°, and 61.5°, with base thicknesses of 1.8mm, 2.1mm, 2.4mm, 2.7mm, and 3mm respectively. During user testing, the rod head's built-in nine-axis MEMS sensor captures angular velocity at a 4000Hz sampling rate, combined with a 1200fps infrared optical system to record the rod face torsional trajectory. The collected data is preprocessed by an edge computing module to generate a parameter set including a center of gravity offset of 2.8mm, a dynamic tilt angle deviation of 0.5°, and 65 effective counterweight combinations.

[0039] During the data analysis phase, 50 effective shot data points within the swing speed range of 48m-52m / s were selected to construct a correlation matrix between the moment of inertia (MOI) and backspin rate. When the optimal shot performance was determined to correspond to center of gravity coordinates X=34.8mm, Y=9.3mm, Z=19.1mm and a total weight of 308g, the NX1980 software was driven to perform parametric modeling: using Maraging 250 steel as the base material, constraining the loft angle to 55.8°, and optimizing the bottom thickness to 25mm, a model was generated.

[0040] The manufacturing stage uses a laser selective melting (SLM) device with a layer thickness of 25μm, a laser power of 400W, and a scanning speed of 7m / s. The optimization mechanism is set so that after accumulating 400 hits or using the device for more than 60 days, if the average swing speed is detected to increase to 54.2m / s, the system will automatically shift the center of gravity 2.2mm towards the heel of the club and adjust the position of the three 5g screws for adaptation.

[0041] like Figure 1 , Figure 2 , Figure 3 As shown, traditional custom clubheads cannot meet the user's requirements for a moment of inertia of 50 g·cm during high-speed swings. 2 To meet the sensitivity requirements, this solution uses a 4000Hz nine-axis sensor and a 1200fps infrared system to compress the dynamic loft deviation to 0.5°. It uses Maraging 250 steel with SLM process to form a 25μm layer thickness, so that the 308g total weight clubhead has a tolerance at the X=34.8mm center of gravity position. This solves the abnormal tailspin rate caused by clubhead deformation during high-speed swings, reduces the standard deviation of backspin, and meets the micro-parameter adjustment requirements of professional-grade equipment, thus solving the problem of abnormal tailspin during high-speed swings.

[0042] Example 3

[0043] A method for obtaining customized products by memorizing golf club head parameters

[0044] It offers an adjustable test rod head with 12 M3 threaded counterweight holes at the bottom and 10 sets of aluminum alloy-copper composite counterweight screws with mass gradients of 0.5g, 1.0g, 1.5g, 2.0g, 2.5g, 3.0g, 3.5g, 4.0g, 4.5g, and 5.0g, for a total adjustment range of 45g. It comes with four interchangeable base angle accessories: rod face tilt angles of 54.0°, 56.0°, 58.0°, and 60.0°, with base thicknesses of 1.5mm, 1.8mm, 2.1mm, and 2.4mm respectively. During user testing, the rod head is equipped with a piezoelectric dynamic force sensor that monitors stress distribution at a 10000Hz sampling rate. Combined with a 2000fps polarized light system, it analyzes rod face deformation and generates a parameter set including a center of gravity offset of 1.5mm, a dynamic tilt angle deviation of 0.3°, and 72 effective counterweight combinations.

[0045] During the data analysis phase, 60 effective shots within the swing speed range of 36-39 m / s were selected, and the sensitivity coefficients of the weight position and takeoff angle were calculated. When the optimal shot performance was determined to correspond to the center of gravity coordinates X = 29.7 mm, Y = 6.5 mm, Z = 16.3 mm and the total weight of 285 g, the NX2000 software was driven to perform parametric modeling: using β-21S titanium alloy as the base material, the loft angle was constrained to 58.5° ± 0.05°, and the bottom thickness was automatically optimized to 1.92 mm to generate the model.

[0046] The manufacturing stage uses a focused ion beam (FIB) processing system with a beam current intensity of 65 nA and an etching accuracy of ±5 nm. The optimization mechanism is set so that after accumulating 350 hits or using the ball for more than 45 days, if the average swing speed is detected to increase to 41.3 m / s, the system will automatically shift the center of gravity 0.8 mm towards the crown and adjust the position of the four 1.5 g screws for adaptation.

[0047] like Figure 1 , Figure 2 , Figure 3 As shown, traditional processes struggle to maintain launch angle stability at low swing speeds. This solution employs a 10000Hz piezoelectric sensor and a 2000fps polarized light system to achieve a center of gravity offset of ≤±1.5mm. A 285g clubhead, manufactured from β-21S titanium alloy with 5nm etching precision via FIB machining, ensures clubface deformation <3μm under a low center of gravity configuration of Z=16.3mm. This effectively solves the trajectory dispersion problem caused by aerodynamic disturbances during low-speed swings, reduces the landing point dispersion diameter, and resolves the trajectory dispersion problem that occurs during low-speed swings in golf.
