The first part may be a part for use in an automobile, aircraft, watercraft, or any vehicle or application where parts need to be joined at an interface. The first part may be formed from any material appropriate for the application.
The second part may be a part for use in an automobile, aircraft, watercraft, or any vehicle or application where parts need to be joined at an interface. The second part may be formed from any material appropriate for the application.
The at least one first or second prolongations may be formed on the surface of the first part, on the surface of the second part, or on the surface of both the first and second parts. The at least one first or second prolongations may be formed on the surface of a part via etching, micro-machining, chemical vapor deposition, or electrical deposition methods. Alternatively, the prolongations may be formed at the time the part itself is manufactured, for example, by a polymeric mold process. The at least one first or second prolongations may include a stem and a bulge. The at least one first or second prolongations may be microscopic, 100 micrometers or smaller in size, or nanoscopic, 100 nanometers or smaller, in size.
The first and second stems 16 and 24 may be generally cylindrical and elongated in shape and dimension and may extend perpendicularly from a surface of the first part 12 or from a surface of the second part 20 and may connect to a bulge 18 and 26.
The stems may alternatively be generally rib shaped and may extend parallel along a surface of a part adjacent to other ribs and may extend perpendicularly from a surface of the first part 12 or from a surface of the second part 20 and may connect to a bulge 18 and 26.
The bulges 18 and 26 may protuberate from the stems 16 and 24 and may be of a general disk or orb shape, though other three dimensional variations are considered to be within the scope of the inventions. In one variation, the bulges 18 and 26 may be generally orb or disc-like in shape. The bulges 18 and 26 bulge may include a first circular side connecting to a stem and a second circular side opposite the first circular side, the first side and second side may be joined by a curved portion having a circumference larger than that of the first circular side and the second circular side such that the bulge is generally disk-like in shape.
The bulges 18 and 26 may alternatively be generally cylindrically shaped and may extend along a top edge of a rib extending parallel and adjacent to other ribs such that the longitudinal axis of the cylindrical bulge runs parallel to the rib.
The first plurality of prolongations may be mechanically bonded to the second plurality of prolongations whereby a first surface of a first part that may include a first plurality of prolongations and may be abutted, under a load, against a second surface of a second part that may include a second plurality of prolongations. The first plurality of prolongations and second plurality of prolongations may temporarily or permanently deform and be caused to mechanically bond together such that each prolongation may be mechanically bonded, but not chemically bonded, to one or more nearby prolongations.
It is understood that although multiple examples have been provided, the prolongations, stems, and bulges may be of any size, shape, or dimensions as desirable for the application and the variations disclosed herein should not be construed to be all encompassing with respect to the scope of the inventions.
According to a first variation, a method may include providing a first part and a second part.
