A three-dimensional (3D) vacuum insulation panel (VIP) and a folding approach to create the 3D VIP from a two-dimensional (2D) VIP of non-uniform thickness for a refrigerator, a refrigerator freezer or a non-appliance, are disclosed. The folding approach includes placing a VIP main panel and a plurality of VIP wall panels on an outer film, where one or more panels are of a greater thickness than other VIP panels; placing an inner film on top of the VIP main and wall panels and sealing the films together. The inner film is longer than the outer film and this allows the films and the VIP wall panels to be folded into a finished panel, wherein the longer inner film allows for fording without causing tears or micro-cracks in the film that would adversely affect the insulation properties of the three-dimensional (3D) VIP.

1. A three-dimensional vacuum insulated panel manufactured from a two-dimensional flat panel of non-uniform thickness, the three-dimensional vacuum insulated panel comprising: an outer film;a flat vacuum insulated panel main wall on the outer film;a vacuum insulated panel top wall on the outer film
1. A three-dimensional vacuum insulated panel manufactured from a two-dimensional flat panel of non-uniform thickness, the three-dimensional vacuum insulated panel comprising: an outer film;a flat vacuum insulated panel main wall on the outer film;a vacuum insulated panel top wall on the outer film adjacent to and at an edge of the main wall;a vacuum insulated panel bottom wall on the outer film adjacent to the main wall and opposite to the top wall;a vacuum insulated panel left wall on the outer film and adjacent to and at an edge of the main wall;a vacuum insulated panel right wall on the outer film and adjacent to the main wall and opposite to the left wall, wherein one or more of the vacuum insulated panel top wall, the vacuum insulated panel bottom wall, the vacuum insulated panel left wall and the vacuum insulated panel right wall have a different thickness than the main wall;an inner film on top of the main wall and each of the vacuum insulated panel top wall, vacuum insulated panel bottom wall, vacuum insulated panel left wall and vacuum insulated panel right wall; wherein the inner film is longer than the outer film,wherein the inner and outer films are sealed, andthe inner film is configured to be of a length wherein folding the vacuum insulated panel top wall, vacuum insulated panel bottom wall, vacuum insulated panel left wall and vacuum insulated panel right wall onto the main wall produces a three-dimensional vacuum insulated panel of non-uniform thickness. 2. The three-dimensional vacuum insulated panel of claim 1, wherein the folded vacuum insulated panel top wall, vacuum insulated panel bottom wall, vacuum insulated panel left wall and the vacuum insulated panel right wall onto the main wall produce a three-dimensional vacuum insulated panel insulation panel free from tears or micro cracks in a film structure, due to the inner film being longer than the outer film. 3. The three-dimensional vacuum insulated panel of claim 1, wherein the inner film being longer than the outer film results in the inner film being folded without tearing or creating micro cracks in the sealed inner and outer films in response to the vacuum insulated panel top wall, vacuum insulated panel bottom wall, vacuum insulated panel left wall and vacuum insulated panel right wall being folded. 4. The three-dimensional vacuum insulated panel of claim 1, wherein the three-dimensional vacuum insulated panel is configured to fill a door dyke of a refrigerator or freezer. 5. The three-dimensional vacuum insulated panel of claim 1, wherein the top wall has a stepped portion of greater thickness than a remainder of the top wall to fill a door dyke of a refrigerator freezer. 6. The three-dimensional vacuum insulated panel of claim 5, wherein the stepped portion prevents air infiltration to a door gasket. 7. The three-dimensional vacuum insulated panel of claim 1, wherein the vacuum insulated panel right wall has two additional vacuum insulated panel walls adjacent thereto that, in response to being folded, are at right angles with one another and are of greater thickness than the remaining vacuum insulated panel walls. 8. The three-dimensional vacuum insulated panel of claim 7 wherein the two additional vacuum insulated panel walls of greater thickness than the remaining walls are configured to provide extra insulation to a compressor. 9. A method of manufacturing a three-dimensional vacuum insulated panel from a two-dimensional flat panel of non-uniform thickness for a refrigerator, a refrigerator freezer or a non-appliance, the method comprising the steps of: providing an outer film;providing a flat vacuum insulated panel main wall on the outer film;providing a vacuum insulated panel top wall on the outer film adjacent to and at an edge of the main wall;providing a vacuum insulated panel bottom wall on the outer film adjacent to the main wall and opposite to the top wall;providing a vacuum insulated panel left wall on the outer film and adjacent to and at an edge of the main wall;providing a vacuum insulated panel right wall on the outer film and adjacent to the main wall and opposite to the left wall, wherein one or more of the vacuum insulated panel top wall, the vacuum insulated panel bottom wall, the vacuum insulated panel left wall and the vacuum insulated panel right wall are thicker than the main wall;providing an inner film on top of the main wall and each of the vacuum insulated panel top wall, vacuum insulated panel bottom wall, vacuum insulated panel left wall and vacuum insulated panel right wall; wherein the inner film is longer than the outer film,sealing the inner and outer films, andproviding the inner film in a length wherein folding the vacuum insulated panel top wall, vacuum insulated panel bottom wall, vacuum insulated panel left wall and vacuum insulated panel right wall onto the main wall produces a three-dimensional vacuum insulated panel of non-uniform thickness. 10. The method of claim 9, wherein the step of folding the vacuum insulated panel top wall, vacuum insulated panel bottom wall, vacuum insulated panel left wall and the vacuum insulated panel right wall onto the main wall to produce a three-dimensional vacuum insulated panel includes preventing tears or micro cracks in a film structure, due to the inner film being longer than the outer film. 11. The method of claim 9, wherein the inner film being longer than the outer film provides stretching of the inner film in response to the vacuum insulated panel top wall, vacuum insulated panel bottom wall, vacuum insulated panel left wall and vacuum insulated panel right wall being folded without tearing or creating micro cracks in the sealed inner and outer films. 12. The method of claim 9, further including the step of providing two additional vacuum insulated panel walls, of greater thickness than the remaining walls, adjacent to the vacuum insulated panel right wall in a manner wherein in response to being folded, the two additional vacuum insulated panel walls are at right angles with one another. 13. The method of claim 12, wherein the two additional vacuum insulated panel walls of greater thickness than the remaining walls are configured to provide extra insulation to a compressor. 14. The method of claim 9, wherein the three-dimensional vacuum insulated panel provides the insulation for a refrigerator or freezer cabinet or a non-appliance. 15. The method of claim 9, wherein the three-dimensional vacuum insulated panel provides the insulation for a refrigerator or freezer door. 16. The method of claim 9, wherein the three-dimensional vacuum insulated panel provides more useable space within a refrigerator freezer.
