Hockey puck and a method for manufacturing the same
The present invention related to a hockey puck configured to transmit a radio signal, the hockey puck comprising: a cylindrical body, a radio Transmitter arranged in a cavity inside the cylindrical body, the cavity machined through a cylindrical surface of the cylindrical body, wherein the radio transmitter is positioned in the cavity with a casting material applied to the cavity. Further, the invention relates to a method for manufacturing the hockey puck.
1. A hockey puck configured to transmit a radio signal, the hockey puck
comprising:
a cylindrical body comprising a flat upper surface and a flat lower surface, and
a radio transmitter arranged in a cavity inside the cylindrical body, the cavity machined through a cylindrical surface of the cylindrical body,
wherein the radio transmitter is positioned in the cavity with a casting material applied to the cavity and wherein the radio transmitter positioned in the cavity comprises a protective layer made of epoxy based compound.
2. The hockey puck according to claim 1 , wherein the casting material is a cast resin based compound.
3. The hockey puck according to claim 1 , wherein the cavity arranged inside the cylindrical body has a width of 35 mm, height of 12 mm and depth of 45 mm.
4. A manufacturing method of a hockey puck configured to transmit a radio signal, the manufacturing method comprising:
machining a cavity in a cylindrical body of the hockey puck, the cavity machined through a cylindrical surface of the cylindrical body, and
positioning of a radio transmitter in the cavity by applying casting material to the cavity,
the manufacturing method further comprising:
treating the radio transmitter with an epoxy based compound for generating a protective layer for the radio transmitter.
5. The manufacturing method according to claim 4 , wherein the machining is performed by milling.
6. The manufacturing method according to any of claim 4 , wherein a first portion of the casting material is applied to the cavity prior to positioning the radio transmitter in the cavity.
7. The manufacturing method according to claim 6 , wherein a second portion of the casting material is applied to the cavity in response to the positioning of the radio transmitter in the cavity on the first portion of the casting material.
8. The manufacturing method according to claim 7 , wherein the second portion of the casting material is applied by injecting it in the cavity through a through hole arranged in a mold housing into which the hockey puck is positioned.
