FIELD: manufacturing technology.
SUBSTANCE: examples of implementation relate to concepts for elastically deformable object (300) of sports inventory, in particular a ball, with following features: at least one deformable structure (200) of electromagnetic coils, which is located around curved surface (202) inside object (300) of sports inventory, wherein said at least one deformable structure (200) of electromagnetic coils is wound in form of a spiral around passing in circumferential direction and curved in accordance with circular surface (202) axis (208) for creation of reserve elongation, which is matched with maximum elastic deformation of object (300) of sports inventory.
EFFECT: possibility to withstand elastic deformation of ball.
