    Hockey puck and a method for manufacturing the same - Jääkiekko ja sen valmistusmenetelmä
    TECHNICAL FIELD
    The invention concerns in general the technical field of sport goods. More particularly, the invention concerns a solution for hockey pucks.
    BACKGROUND
    Ice hockey is a team sport usually played on ice in which players of two teams use their sticks to take a hockey puck to opponent’s goal. The ice hockey is 10 known to be contact sport which is fast and physical game. The hockey puck is cylinder-shaped and nowadays made of a vulcanized rubber. A standardized ice hockey puck is black, 25 mm thick and 76 mm in diameter with a weight between 156 g and 170 g.
    As mentioned the ice hockey is a fast game and it is challenging to follow by 15 audience, but also by team officials, such as coaches. In order to gather more detailed information on the game there are developed solutions in which at least the hockey puck is equipped with an applicable radio transmitter and a motion of the ice puck is followed on the field with a measurement system. For example, the measurement system may refer to some indoor positioning system, which 20 may determine a position of the hockey puck on a basis of radio signal obtained from the hockey puck by a plurality of sensors. In some sophisticated solutions the players may also carry the radio transmitter and thus it is possible to monitor players’ positions on the field. By analyzing the obtained position information on the different parties, it is possible to generate enriched information on the game 25 to parties willing to receive it.
    During the use of the hockey puck it receives a lot of shocks from multiple sources. When the puck is shot it receives a huge force from a hockey stick and the shot may end up to goal frames, which are made of metal, or to a hockey
    20176139 prh 20 -12- 2017 rink structure. As is clear, the hockey puck receives a high shock when the puck hits the goal frame or rink structure. Moreover, the puck gets impact from other sources, such as from skates of the players and so on.
    In the existing solutions the radio transmitter is mounted to the hockey puck by drilling an opening to a flat surface (i.e. a top or a bottom) of the puck and by positioning the radio transmitter therein, and applying applicable material to the opening into which the radio transmitter is positioned so that a shape of the puck may be recovered. However, the puck manufactured in the described manner has turned out to be fragile and it does not stand the shocks during the game.
    Moreover, a reconstruction of the hockey puck in the described manner has effect on characteristics of the puck in use. For example, the puck does not slide on ice in a similar manner as it used to and a balance of the puck structure may be affected.
    Hence, there is need to develop the hockey pucks and the manufacturing meth15 ods further in order to introduce hockey pucks applicable to the game, which pucks at least in part mitigate the drawbacks of the existing solutions.

    DESCRIPTION OF THE EXEMPLIFYING EMBODIMENTS
    The specific examples provided in the description given below should not be construed as limiting the scope and/or the applicability of the appended claims.
    20176139 prh 20 -12- 2017
    Lists and groups of examples provided in the description given below are not exhaustive unless otherwise explicitly stated.
    Figure 1 schematically illustrates a hockey puck 110 according to an embodiment of the invention. The hockey puck structure has a cylindrical body having 5 a flat upper surface 112 and a flat lower surface 114 and a cylindrical surface 116. A radio transmitter 130 is arranged inside the hockey puck 110 through a cavity 120 machined to the hockey puck 110 so that a mouth of the cavity 122 is arranged on the cylindrical surface 116 of the body.
    Figures 2A and 2B schematically illustrate the hockey puck 110 according to an 10 embodiment of the invention from other perspectives. Figure 2A illustrates a cross-sectional view of the hockey puck 110 according to an embodiment of the present invention. Figure 2B illustrates an elevational cut-away view of the hockey puck 110 according to an embodiment of the present invention.
    According to an embodiment of the invention the radio transmitter 130 consisting 15 of electrical components, such as a radio module with an antenna, processor, a memory, a battery, may be treated with an applicable compound for generating a protective layer for the radio transmitter, and especially for the electrical components therein. The treating with the applicable material may advantageously be made prior to positioning the radio transmitter in the cavity of the body. The 20 applicable material for generating the protective layer may e.g. epoxy based compound. For example, epoxy resin may be used for overcasting the radio transmitter chip. The generation of the protective layer on at least portion of the radio transmitter improves a mounting of the electrical components on the printed circuit board and, thus, an endurance of the radio chip to external shocks 25 may be improved.
    The positioning of the radio transmitter in the cavity may be implemented so that the radio transmitter is taken in the cavity into which an applicable casting material is input (the casting material is schematically illustrated in Figure 2A). The radio transmitter is positioned in the casting material and the cavity is filled with 30 the casting material so that the radio transmitter gets covered with the casting
    20176139 prh 20 -12- 2017 material. Naturally, the casting material may be manipulated on the cylindrical surface 116 so that the shape of the hockey puck 110 may also be recovered.
    The size of the cavity is advantageously selected so that it enables a durability of the hockey puck 110 according to the present invention. In an advantageous embodiment the size of the cavity is such that a width of the opening is 35 mm (i.e. in a direction perpendicular to a direction of a normal of the flat upper or flat lower surface (marked as X axis in Figure 1)) and a height is 12 mm (i.e. a direction parallel to a direction of a normal of the flat upper or flat lower surface (marked as Y axis in Figure 1)), whereas a depth of the cavity is preferably 45 10 mm. Further, the machining of the cavity to the mentioned size has an advantage that a weight of the hockey puck 110 may be returned as standardized weight with the manufacturing process as described. Still further, the cavity size as described is optimal for a radio communication i.e. an absorption of the radio signal originating from the radio transmitting may be optimized.
    The radio transmitter 130 arranged inside the hockey puck 100 in the manner as described above may be configured to implement any radio communication technology which is detectable by a measurement system by means of which at least a position information on the hockey puck 100 may be generated. In other words, the radio transmitter may transmit a signal in any frequency, preferably at radio frequency (RF). According to an embodiment of the invention the radio transmitter implements a short-range radio communication, such as Bluetooth® communication.
    Next, a method for manufacturing a hockey puck 110 according to an embodiment of the present invention is described by referring to Figure 3. The manu25 facturing method as depicted in Figure 3 is a non-limiting example for describing at least some steps of the method.
    Regarding step 310:
    First, a hockey puck 110 made e.g. of a vulcanized rubber may be machined with an applicable machining method for generating a cavity 120 in the hockey 30 puck 110. According to the present invention the cavity 120 is generated so that
    20176139 prh 20 -12- 2017 the cavity 120 opens, i.e. a mouth of the cavity 122, on the cylindrical surface 116 of the body. A preferred machining method is milling with a milling tool, i.e. a milling cutter, which is configured to mill the cavity 120 with predefined dimensions to the hockey puck 110. For example, the milling tool may be programma5 ble to perform a milling operation when the dimensions of the cavity 120 is provided as an input. Naturally, the hockey puck 110 to be milled is positioned so that the machining operation may be performed to it.
    In some embodiment of the manufacturing method the machining is performed to a plurality of hockey pucks 110 simultaneously. The hockey pucks 110 may 10 be positioned in a bench which is served e.g. to a milling tool, which comprises a plurality of milling knifes advantageously for machining the hockey pucks 110.
    Regarding step 320:
    In response to the generation of the cavity 120 in the hockey puck 110 a first portion of a casting material may be applied in the generated cavity 120. The 15 first portion of the casting material is applied in the cavity 120 for receiving and positioning a radio transmitter 110 thereto.
    Regarding step 330:
    The radio transmitter may be positioned in the cavity 120 wherein the first portion of the casting material is applied for forming a bed for the radio transmitter 110.
    Advantageously the casting material is such that the radio transmitter chip is engaged in a fixed manner thereto at least when the casting material gets cured. The radio transmitter 110 may advantageously be supported with necessary supporting means, such as with an applicable support arm, in order to position the radio transmitter 110 accurately in the cavity 120.
    Regarding step 340:
    Finally, a second portion of the casting material is applied in the cavity 120 for filling the cavity in full with the casting material. According to an embodiment prior to application of the second portion of the casting material in the cavity 120
    20176139 prh 20 -12- 2017 the hockey puck 110 may be positioned in a mold housing, which forms a structure around at least portion of the hockey puck 110 in order to maintain a shape of the hockey puck 110 when the second portion of the casting material is applied in the cavity. For example, the mold housing may consist of two parts form5 ing a mold for the hockey puck 110 under manipulation when the two parts are coupled, such as locked, against each other. According to an embodiment a through hole is arranged in the housing in order to apply the second portion of the casting material in the cavity 120 of the hockey puck 110 when the mouth of the cavity 122 is aligned with the through hole.
    The cylindrical surface of a hockey puck 110 is typically patterned with grooves or similar. The patterns may also be generated to the casting material input to the cavity by patterning an inner surface of the mold housing facing the input casting material with the desired pattern, and in response to positioning the hockey puck 110 under manufacturing in the mold housing the desired pattern 15 is generated to the casting material.
    In the above described method applying of the casting material at the steps 320 and 340 may be performed by injecting the casting material in the cavity 120. According to an embodiment of the present invention the casting material may be cast resin based compound. For example, cast resin dedicated for electronics 20 may be used. An example of the cast resin may e.g. be a compound known as electrical polyurethane resin consisting of polyol and isocyanate. A ratio of the materials when used may e.g. be 4:1, correspondingly. Generally speaking, the casting material has advantageously a hardness close to a hardness of the material of the hockey puck 110, i.e. typically vulcanized rubber. Preferably the 25 hardness is a bit lower than the hardness of the hockey puck 110 in order to enable shock absorption at least in part. For example, the hardness of the standardized material of the hockey puck is 85 (Shore value) whereas the hardness of the electrical polyurethane resin consisting of polyol and isocyanate applied as the casting material in an embodiment of the present invention is 80 (Shore 30 value).
    20176139 prh 20 -12- 2017
    In some other embodiment the radio transmitter 130 may be treated separately prior to positioning it in the cavity 330. The treating may refer to a generation of a protective layer to at least portion of the radio transmitter chip. For example, only one side of the chip may be treated with the material forming the protective layer or only portion of that. In some embodiment the radio transmitter 130 is fully covered with the protective layer. As mentioned, the protective layer may be formed e.g. with a epoxy based material, for example.
    The use of the mentioned compounds for manufacturing the hockey puck 110 transmitting radio signals may require drying of the compound before proceed10 ing to the next step in the method. Hence, for example after applying the first portion of the casting material 320 and positioning the radio transmitter thereto
    330 it may be necessary to let the casting material to dry before proceeding with the step 340. The same applies after the step 340 before the hockey puck may be taken into use. As is clear the duration of the drying period is at least in part 15 dependent on the compound in use, but typically it is from several days to several weeks. The same applies with the form of the protective layer for the radio transmitter 130.
    As the radio transmitter 130 requires electrical energy for use it may comprise a battery configured to provide the energy for generating the radio signal for the 20 measurement system.
    The method for manufacturing the hockey puck 130 configured to transmit radio signals, and the hockey puck 130 itself, has an advantage that a friction surface does not change due to the manufacturing process in which the mouth of the cavity 122 is machined on the cylindrical surface 116 of the hockey puck 110. 25 As well, a surface tension may be maintained the same as with a traditional hockey puck 110 not having the radio transmitter inside. The material selections as described, as well as the optimal selection of the size of the cavity 120, improves the endurance of the hockey puck 110 in order to tolerate hard external shocks as well as deceleration of the puck when used in hockey game. Addi30 tionally, the radio signal originating from the radio transmitter 130 is only absorbed in an acceptable amount thus enabling a detection of the hockey puck
    110 with a measurement system implemented in the environment in which the hockey puck 110 is used to, such as around the hockey rink.
