Description

[0001] The present invention relates to the technical field of sports equipment and, in particular, to an intelligent table tennis racket suitable for recording hitting movements, a handle component that can be attached to a racket, a motion detection system, an application for evaluating the data collected by the intelligent table tennis racket, and a method for manufacturing the handle component.

[0002] In general, process data is recorded in order to better analyze and understand these processes. Sensors, which can record movement sequences in particular, have become smaller and smaller over time, so that their areas of application have constantly expanded. The sports industry is also an economically significant area in this context, so that in sports too, (movement) data of athletes and / or sports equipment are increasingly being recorded while practicing the sport so that conclusions can be drawn. This data can be used to enable athletes to retrospectively analyze and improve their movement sequences, but also to verify referee decisions, for example. Endurance athletes in particular have been recording their body data for some time.Using wearable sensors (e.g. chest strap, wristband or watch), heart rate, speed and GPS data are measured and sent to a smartphone, for example.

[0003] While the recording of such data was for a long time limited to endurance sports, this technology is increasingly finding its way into racket and ball sports.

[0004] For tennis, for example, the company Head sells external sensor modules that can be clipped onto the grip from the outside, and whose transmitted sensor data can be used to count the strokes of the game via an app. Garmin offers a similar concept for golf clubs. For soccer players, there is the "Playermaker" wearable, which delivers data to both feet for statistical analysis of one's game.

[0005] In table tennis, there are currently no commercial products that record movement data and draw conclusions. Initial studies on this topic have been conducted in the work of Dr. Peter Blank (https- / / www.researchgate.net / publication / 343205067_Smart_Racket_-_Instrumented_Racket_as_Real-time_Feedback_Device_in_Table_Tennis). However, the solutions presented there still have some disadvantages, which, in particular, mean that the table tennis racket presented there does not play "normally."

[0006] A few of these disadvantages are outlined below. Similar to other sports, the sensors are attached as an external module to the end of the racket handle. This significantly changes both the weight and the center of gravity of the table tennis racket.

[0007] This is less significant in other sports, because, for example, a tennis racket weighs an average of 300 g or a golf club weighing between 440 g and 800 g, which is significantly heavier than a table tennis racket at approximately 75 g (without rubbers). Moreover, even ambitious amateur table tennis players are extremely sensitive to the weight, shear point, and playability of their racket. Furthermore, Blank's work shows sensors whose electrical circuits are exposed and unprotected on the racket blade.

[0008] Some embodiments in Blank's work also indicate that inserting the sensors will at least damage the blade of the table tennis bat. In order to describe the feel of a table tennis bat for a player, it is important to understand its construction. Such a bat consists of three main components: a blade made of veneered wood, two rubber coverings, and two so-called grip shells in the handle area, which are attached to the blade and allow the player to hold the bat securely during play. Table tennis bat manufacturers put a lot of development work into the blade of the bat, as it is crucial for the bat's playing characteristics. Put simply, stiffness, for example, influences the speed of the balls returned.For this reason, several layers of numerous high-tech materials (such as carbon or Dyneema) are sometimes used and combined to produce the veneer of the racket blade. The damage to the blade, as seen in the blank, adversely affects the playing characteristics of the racket. In particular, the racket loses strength, and players complain of "slow balls" (such a racket is then referred to as "slow" among table tennis players). In addition to the impaired playing characteristics, the risk of the racket breaking and / or undesirable vibration during hitting due to damage to the blade also increases.

[0009] In table tennis in particular, the compactness of a table tennis bat, the way in which the bat is manufactured from wood and the sensitivity of table tennis games to weight changes / vibrations pose special requirements for the provision of a sensor in a table tennis bat.

[0010] EP 0 701 844 A2 discloses a table tennis bat consisting of a frame with a handle and a blade with a differentiated structure to impart predetermined reaction and bounce characteristics to the bat upon impact with the ball, particularly suitable for sports games and competitions. Furthermore, a table tennis bat is shown with a vibration band incorporated into the handle, which provides the player with immediate, enhanced vibration feedback of the ball impact point during play.

[0011] CN 103357153 A describes a table tennis system primarily designed for use by coaches in training situations. The system displays the trajectory and racket angle on a display to guide students. For stability and protection, the system teaches how to fully integrate a sensor module into a handle and seal it with a protective plate.

[0012] The object of the invention is therefore to provide technical solutions for table tennis, which enable data from the table tennis game to be recorded without adversely changing the playing characteristics of the racket.

[0013] Solved for this task with the features of the independent claims.

[0014] The features of the various aspects of the invention or the various embodiments described below can be combined with one another unless this is explicitly excluded or technically mandatory.

[0015] To provide further understanding, we will begin by explaining some typical terms related to table tennis bats. The handle of a table tennis bat typically consists of two handle shells, known as the upper and lower handle shells, which are attached to different sides of the handle area of ​​the bat blade and thus form the handle of the bat. Since the terms upper and lower handle shell are merely conventions and change when the bat is rotated 180° around its longitudinal axis, the term handle shell component is used below instead of the term upper and lower shells, which can refer to either the upper or lower handle shells. Consequently, the handle of a table tennis bat comprises a first and a second handle shell component.

[0016] According to the invention, a handle shell component is specified, wherein the handle shell component comprises a handle shell body comprising a first surface which is designed as a gripping surface for contact with a player's hand and a second surface which is designed as a contact surface with a club blade, wherein the handle shell body has a recess in sections on the first surface and / or on the second surface and wherein a sensor module is at least partially, in particular completely, introduced into the recess.

[0017] An alternative formulation of the invention is as follows: According to the invention, a handle shell component is specified, wherein the handle shell component comprises a first segment, wherein a first surface of the first segment is configured as a gripping surface for contact with a player's hand; a second segment, wherein a first surface of the second segment is formed as a contact surface with a club face, wherein the first surface of the first segment has a recess in sections, or wherein the first surface of the second segment has a recess in sections, and wherein a sensor module is at least partially, in particular completely, inserted into the recess. The handle shell body can thus be formed in one piece or in two pieces from the first and second segments. If the sensor module is not fully but only partially housed in the recess, then another recess can be provided in the clubface to accommodate the remaining part of the sensor module. The advantages regarding playing behavior when the sensor is fully housed in the grip component are discussed below. The variant of accommodating the sensor module jointly in the recess of the grip component and in the additional recess of the clubface offers the advantage of allowing more flexible design of the overall size of the combined recess.

[0018] The first and second segments can be formed as a single piece, in particular from a single piece of wood. However, it is also possible to manufacture the first and second segments separately and then to join them together detachably or permanently, in particular by gluing them. If the first and second segments are formed as a single piece of wood, it can still be useful to refer to them as the first and second segments, as both segments are designed differently depending on their functionality. The surface of the first segment has corresponding curvatures or curves in order to adapt as closely as possible to the anatomical shape of a player's hand, whereas the surface of the second segment is designed to be as flat as possible, as it is on this surface that the glue is typically applied to connect the handle scale component to the club face.

[0019] The following refers to the formulation "without" segments. It is readily apparent to those skilled in the art how the following features could be applied to the alternative formulation.

[0020] A recess is incorporated into the grip shell body starting from the first surface, the volume of the recess being at least larger than the sensor module, such that the sensor module can be reliably inserted into the recess in the first surface. Since the first surface is the one that is in contact with the player's hand, a cover can be placed over the recess after the sensor module has been inserted into the recess, so that the sensor module is protected, in particular, from sweat and the player feels the recess as little as possible and the cover feels completely normal to him. In this respect, it is advantageous to design the cover so that it feels at least similar to a first surface without a section-based recess.If the cover is detachably attached, the sensor module can be easily replaced in this variant, even if the grip component is glued to the club face.

[0021] The recess is machined into the grip body in sections, starting from the second surface, with the volume of the recess being at least larger than the sensor module, so that the sensor module can be reliably inserted into the recess of the grip body. To connect the grip component to the club face, the second surface is glued to the club face. In this case, the club face forms the protected "end" for the sensor module against external environmental influences, since the first surface in this case has no recesses and is made continuously, in particular from wood, and reliably protects the sensor module from above.

[0022] Another possibility is to provide a recess that completely penetrates the entire grip shell body, i.e., both the first surface and the second surface. This case is described by the following combination of features: the first surface and the second surface of the grip shell body have a recess at least in sections. In this case, again, as described above, the first surface is provided in such a way that a cover can be attached.

[0023] The grip shell component according to the invention has the advantage that the sensor module can be fully and securely integrated into the handle / racket without damaging the racket blade or adversely altering the playing characteristics of the table tennis racket. The invention also makes it possible to retrofit existing rackets with a sensor module by simply removing at least one of the grip shell components and replacing it with the grip shell component according to the invention, which has a sensor. Such a replacement of the grip shell component is particularly easy for employees of table tennis shops. Thus, the player's playing data can now be recorded without impairing the player's playing experience or changing the racket's external appearance.

[0024] The sensor module is configured to record data suitable for characterizing the player's playing behavior and to transmit the data wirelessly and / or via cable. The sensors are therefore suitable for recording data that can be used, in particular, to differentiate between movement sequences of shots. This advantageously allows a player to analyze their game based on the collected data and / or to draw conclusions about the condition of the racket's material, in particular the condition of the rubbers. The conclusion regarding the material condition is based on the knowledge that the player's stroke movement with older rubbers that are already worn out and can transmit less spin to a ball differs from the player's stroke movement with newer rubbers. An app to which the data is sent can then inform the user when it is time to replace old rubbers with new ones.The data can also be processed via the app in such a way that the player can graphically display their game analysis. This allows them to draw conclusions to improve their game. The sensor module can therefore preferably include the following sensors capable of capturing the relevant data: motion sensors, such as accelerometers, gyroscopes, and / or magnetometers. The sensor module can also incorporate a microphone that records sounds.

[0025] The sensor module can also include one or more feedback units, such as a haptic module in the form of an unbalance motor, a loudspeaker, and / or a lighting unit (e.g., a multi-colored LED). Previous feedback to players was only provided with a time delay, for example, by displaying it on an external screen via an app. During a game, an athlete will not be able to use such feedback, especially if they are concentrating on the opponent or the ball. The integrated feedback units give the player the opportunity to receive haptic, auditory, and / or visual feedback during the game. This type of feedback can be controlled via the connected device and can be switched on or off, for example. As a concrete example, feedback could be generated that shows the user whether they have hit a ball correctly.

[0026] The sensor module preferably has a processor that processes the data from the various sensors and prepares it for transmission. In addition, the sensor module can have a radio module that can transmit the data, in particular the pre-processed data, for example via Bluetooth or WiFi to a terminal device on which the game and / or material analysis application is installed. Such a terminal device is in particular a smartphone, a tablet and / or a computer. It is also possible for the data to be transmitted via cable, for example via a USB interface assigned to the sensor module. This has the advantage that a battery of the sensor module can potentially also be charged via the USB interface, whereby the handle shell inevitably has an opening through which sweat and other moisture can penetrate to the sensor module.However, it is also possible to provide appropriate protective cover in this case.

[0027] Preferably, a cover can be attached to the recess of the first surface to enclose the sensor module inside the handle shell component for protection against external influences. This embodiment has already been explained above.

[0028] In a preferred embodiment, the sensor module is glued, screwed, or clicked into the recess. The sensor module can therefore be glued, screwed, and / or clicked. Clickable describes in particular the use of a click closure, which can be realized in a manner known per se using a positive fit and / or a friction fit. In particular, a plastic component can be used here, which can be molded particularly efficiently and is appropriately equipped to realize the positive and / or friction fit. This has the advantage that such a plastic part with a positive and / or friction fit can be manufactured much more easily than if geometric adjustments that create a positive and / or friction fit are made directly on the recess, which is typically made of wood.The plastic component can then be connected, in particular glued, to the recess, and the sensor module can be clicked into the plastic component. This makes it possible for the recess to have an easily manufactured square or round shape, particularly with smooth walls. Clicking the recess has the advantage that the sensor module can be easily inserted into the recess and removed again. Clicking the recess is therefore also resource-saving and environmentally friendly. The advantage of gluing is that in this case, the structural adjustments to the sensor module and the recess are likely to be minimal.

[0029] The sensor module is expediently designed as an encapsulated sensor module as an ESD protection measure. In this context, it should be noted that table tennis bats are manufactured in wood factories. These production facilities usually lack expertise in handling and processing electronic components that require special protective measures. Manufacturing with appropriate ESD protection measures would incur considerable costs. However, if the sensor module is already provided as an encapsulated sensor module, especially to the wood factory, further processing can be carried out safely. Furthermore, there is no exposed electronics in this case, so the encapsulated sensor module is also protected from sweat and moisture, which the sensor module can come into contact with, especially when playing with a table tennis bat.Encapsulating the electronics into an internal module also has the advantage that the manufacturing process for the entire racket can be easily divided into two sequential, independent steps. In the first step, the electronics board is assembled and encapsulated. Most electronics assemblers offer this "encapsulation step" as a standard production step, for example, by potting or installing it in a plastic housing. In the second production step, the encapsulated electronics, i.e., the sensor module, can be easily installed in the wood factory. Encapsulation eliminates the need for additional electronics workstations or measures related to handling electronic components.

[0030] The sensor module preferably comprises a battery power supply, wherein the battery is rechargeable via a USB port and / or by induction. The advantage of the USB port is that it can also be used to transfer data, and users typically already have the appropriate USB charging cable. Charging via induction has the advantage that the sensor module can be installed completely inside the grip body and is thus protected from liquids. When charging via induction, it is also possible to optimize the material of the grip shell component so that charging via induction is as energy-efficient as possible.

[0031] The recess is advantageously aligned with the sensor module in such a way that the center of gravity of the recess and the sensor module of the grip shell component integrated therein corresponds to the center of gravity of the grip shell component without the recess. This has the advantage that, ideally, the player will not notice any difference in the playing behavior of the table tennis racket.

[0032] To enable the direct integration of the sensor module into the racket handle, material, particularly wood, is removed from the handle body or the first segment and / or the second segment of the handle component during the production process of the handle component, thereby creating the recess. The material can be removed, for example, by drilling, punching, or milling. This process can, in principle, also be performed retrospectively on conventional handle components without a sensor module that have already been connected to a racket. The recess must be provided in such a way that its volume is at least as large as the sensor module.

[0033] The sensor module can be encapsulated in a further production step, as described above. In the next step, the sensor module can be inserted into the recess, for example by gluing, clicking or screwing. The now finished handle component is then attached to the club face in a further step, in particular by gluing the first surface of the second segment of the handle component to the club face. By directly indicating in the handle component, the material removed from the interior of the handle component reduces the original weight of the handle component and thereby compensates for the additional weight of the sensor module. The sensor module can, for example, have the shape of a cuboid, with the internal arrangement of the individual components selected so that the center of gravity of the module lies in the geometric center of this cuboid.This allows the center of gravity and the weight of the removed, particularly milled, material of the handle shell component to be precisely compensated during the manufacturing process.

[0034] If the sensor module is heavier than the geometrically minimum required recess for the sensor module, the cutout can be made larger, resulting in a larger recess than geometrically necessary for the sensor module. By positioning the sensor module appropriately centrally, a center of gravity can be achieved that corresponds to that of the original handle shell component.

[0035] If the sensor module is lighter than the milled material, the recess can correspond exactly to the size of the sensor module and the sensor module can be brought to the required weight by additional weights.

[0036] A further advantage of the manufacturing process is that already purchased table tennis bats can easily be retrofitted with the handle shell component according to the invention.

[0037] According to the invention, a table tennis bat is further specified, wherein the table tennis bat has a two-sided racket blade with an area, in particular approximately elliptical, for attaching rubber coverings and a grip area extending longitudinally from the racket blade; two rubber coverings, which are detachably connected to the racket face, two handle shell components, wherein a first handle shell component is connected to a first side of the handle area and a second Handle shell component is detachably connected to a second side of the handle area, wherein at least one of the handle shell components is designed like the handle shell component according to the invention.

[0038] The racket according to the invention offers the player the advantage of being able to record data related to their game without adversely affecting the racket's playing characteristics thanks to the built-in sensor module. In particular, the player can use their existing racket and simply upgrade it with the grip component according to the invention. It is also possible to distribute the sensors across two different grip components.

[0039] In addition, the invention provides an application (app) which is designed to analyze and evaluate the playing behavior of a table tennis player and / or the material condition of a sports racket, in particular a table tennis racket. This app can in particular be installed on a terminal device of the player and programmed with corresponding algorithms to carry out the analysis and evaluation. The terminal device is preferably configured to receive the sensor data. The terminal device can therefore be coupled to the sensor module in a data-conducting, wired and / or wireless manner. Votes can be implemented in the algorithms which, for example, indicate accelerations at the time of a hit, racket speeds, and the like, and which can in particular be compared with past data.In particular, neural networks can also be stored, which can be used to analyze the playing behavior and / or the condition of the material, in particular the surfaces.

[0040] For example, the neural network for analyzing playing behavior could be trained with data that traditionally corresponds to a technically correct movement sequence. For example, a first data set might correspond to a correctly executed forehand stroke, while a second data set might correspond to an incorrectly executed forehand stroke. Through appropriate labeling, the neural network then learns to distinguish between technically correct and incorrectly executed movements. The training data is preferably recorded using the same sensors as the sensor module.

[0041] If the player's actual stroke movements, extracted from the sensor module's real-world measured sensor data, are then passed to the neural network, the app can graphically display whether and to what percentage the player's strokes are classified as correct or incorrect. With appropriate training data, the neural network is also able to differentiate between individual stroke techniques, such as forehand, backhand, topspin, backspin, etc.

[0042] Another possible feature is the use of training data sets from professionals to generate the training data. The neural network would then classify whether a shot was executed in a way that corresponds to that of the corresponding professional. In this way, the app could guide the player to play like Timo Boll, for example, or to specifically create "special shots" of certain professionals. For example, a backhand like Timo Boll and a forehand like Dirk Müssig. The corresponding data sets can be input by the players for this application, especially with the intelligent table tennis bat.

[0043] However, training data sets can also be used that reflect the movement sequences of a racket with new rubbers on the one hand, and other training data sets that reflect the movement sequences of a racket with worn rubbers at various stages of wear. The player's actual sensor data can then be classified by the neural network to determine the wear and tear of the player's table tennis rubbers. The app could then alert players that it is time, for example, to replace the worn-out rubbers with new ones. Neural networks have proven to be particularly powerful and flexible for such classifications. Alternatively, heuristic formulas can also be used. This means that key parameters for individual strokes can be determined, such as stroke speed, stroke angle, error rates, and other factors.Other variables, such as the frequency at which the wood resonates after a blow, can also be measured. These variables change with increasing material wear. Especially in the case of heuristic formulas, a statistical evaluation of the mean, standard deviation, and / or extreme values ​​can be performed, for example, to make statements about changes in the material's condition.

[0044] Material conditions can also be "recorded" and analyzed in other sports. In tennis, the tension of the strings decreases with frequent play. Consequently, tennis players restring their rackets more often. I would be able to measure this with our approach, too.

[0045] In golf, the “grooves” in the clubface become clogged and the ball no longer gets as much spin.

[0046] A further aspect of the invention is a motion detection system of movement sequences of a table tennis player comprising a table tennis racket according to the invention, which is designed to collect data suitable for characterizing the playing behavior of a player and to transmit the data wirelessly and / or via a cable; an application according to the invention implemented on a user terminal, wherein the user terminal is configured to receive the data and wherein the application is programmed to analyze and evaluate the playing behavior and / or a material condition of the table tennis bat.

[0047] As already described above, this motion capture system can be used to record and analyze playing behavior and / or the condition of the material.

[0048] According to a further aspect of the invention, a method for producing the handle shell component according to the invention is provided, comprising the following steps: Providing a handle shell body, in particular made in one piece from wood; Introducing a section-wise recess into the handle shell body, wherein the recess has at least the size of a sensor module; Glue, click or screw the sensor module into the recess.

[0049] This creates the handle shell component.

[0050] In one embodiment, it may be possible for the sensor module to not fit completely into the grip component. In this case, it is possible for the sensor module to protrude from the recess, and for an additional recess to be provided on the club face, in particular by a non-continuous milling. The recess in the grip component and the additional recess in the club face together form the receiving area for the sensor module.

[0051] In the following, preferred embodiments of the present invention are explained with reference to the accompanying figure: Fig. 1: shows a cross-section along a longitudinal axis of a table tennis bat according to the invention and the corresponding motion detection system.

[0052] Numerous features of the present invention are explained in detail below using preferred embodiments. The present disclosure is not limited to the specifically mentioned feature combinations. Rather, the features mentioned here can be combined in any desired way to form embodiments of the invention, unless expressly excluded below.

[0053] Fig. 1 shows a cross-section along a longitudinal axis of a table tennis racket 101 according to the invention and the corresponding motion detection system 100.

[0054] The table tennis racket 101 comprises a racket blade 105, which is in particular of continuous design, wherein a first table tennis covering 110 and a second table tennis covering 115 are detachably connected to a region of the racket blade 105 on opposite sides. A first handle component 120 and a second handle component 121 are detachably attached to another region of the racket blade, also on opposite sides, wherein the first handle component 120 and the second handle component 121 form the table tennis racket 101.

[0055] The first grip component 120 has a recess 126 in its grip body 125 into which a sensor module 130 is fully integrated. Preferably, the club face 105 remains intact. If the electronics of the sensor module 130 are encapsulated, this also provides protection against liquids. The sensor module 130, in combination with the recess 126, is designed so that the playing feel is not adversely affected. In particular, this is achieved by a corresponding weight and center of gravity adjustment, which is to be provided such that the weight and center of gravity of the grip component 120 correspond to those of the second grip component 121.

[0056] The sensor module 130 can record measurement data that characterizes the game of a table tennis player and send it via the radio connection 135 to a terminal device 140, in particular to a smartphone 140. An application is implemented on the smartphone 140 that evaluates the game data and draws conclusions about the player's playing behavior and / or material wear, in particular of the rubbers 110, 115. The analysis data generated by the application is displayed on a graphical output 150 of the smartphone 140 in order to guide the player either regarding their playing style and / or regarding a rubber replacement.

[0057] The invention enables table tennis players to buy an intelligent table tennis bat or to upgrade their old bat to become an intelligent table tennis bat in order to be able to intelligently analyze and evaluate their game data using the associated app.
