Device cover assemblies for portable device protection inside receptacles
The disclosure describes a system or an apparatus for providing protection for a device. In one aspect, the system or the apparatus includes an outer cover and an inner cover. The inner cover fits inside the outer cover, and the device may be inserted inside the inner cover. A closed end of the inner cover sits higher than a closed end of the outer cover, creating an air gap between the closed ends of the inner and outer covers. The air gap may provide shock absorption for the device. The inner cover may also include one or more perforations of the composite material of the inner cover. The one or more perforations may provide a slinging motion of the device, which help increase shock absorption, provide shock dampening from the motions of the device, and/or increase elastoplasticity of the composite material of the inner cover.
1 . A system for providing protection for a device, the system comprising:
an outer cover having a first outer length, a first inner width, a first depth, and one or more tabs; and
an inner cover having a second outer length, a second inner width less than the first inner width, a second depth, and one or more cutouts having a size corresponding to a size of the one or more tabs, the inner cover configured to store the device,
wherein the inner cover is configured to fit inside the outer cover,
wherein the outer cover comprises a first closed end and the inner cover comprises a second closed end sitting higher than the first closed end, and
wherein the one or more cutouts are configured to receive the one or more tabs to attach the inner cover to the outer cover.
2 . The system of claim 1 , wherein the inner cover comprises a first side wall and a second side wall at a first end and a second end of the second outer length, respectively, and
wherein the first and the second side walls are configured to prevent the device from sliding off the inner cover when the device moves along the second outer length.
3 . The system of claim 1 , wherein the device comprises a laptop computer.
4 . The system of claim 1 , wherein the first depth and the second depth less than the first depth are configured to provide a gap between the first closed end and the second closed end, the gap configured to provide shock absorption for the device.
5 . The system of claim 4 , wherein the inner cover comprises a first lip and a second lip along a first open end and a second open end, respectively,
wherein the outer cover comprises a first open end and a second open end,
wherein the first lip and the second lip are configured to be in contact with the first open end and the second open end of the outer cover respectively, and
wherein the contacts between the first and second lips of the inner cover and the first and second open ends of the outer cover are configured to stabilize the air gap to prevent shrinking, collapsing, or a combination thereof due to motions of the device.
6 . The system of claim 1 , wherein the outer cover comprises a first composite material, and the inner cover comprises a second composite material, and
wherein the second composite material has greater elastoplasticity than the first composite material.
7 . The system of claim 6 , wherein the first composite material comprises a polyethylene (PE) material, and the second composite material comprises a thermoplastic polyurethane (TPU) material.
8 . The system of claim 6 , wherein the outer cover comprises a plurality of molded rib-like structures of the first composite material to increase a rigidity of the first composite material, a structural strength of the outer cover, or a combination thereof.
9 . The system of claim 6 , wherein the inner cover comprises a plurality of perforations of the second composite material configured to increase a slinging motion of the device, to increase shock absorption from the motions of the device, to dampen shock from the motions of the device, to increase elastoplasticity of the second composite material, or a combination thereof.
10 . The system of claim 1 , wherein the inner cover comprises one or more extruded geometric shapes at a bottom of the closed end of the inner cover, and
wherein the one or more extruded geometric shapes are configured to provide further shock absorption from the motion of the device.
11 . The system of claim 10 , wherein the one or more extruded geometric shapes comprise one or more hexagonal extruded shapes.
12 . The system of claim 10 , wherein each of the one or more extruded geometric shapes comprises a three-dimensional (3D) volumetric region, wherein the 3D volumetric region is defined by a cuboid, a polyhedron, a cylinder, a sphere, a cone, a pyramid, a prism, a torus, or a combination thereof.
13 . The system of claim 1 , wherein the outer cover is configured to fit inside a bag.
14 . The system of claim 13 , wherein the bag comprises a laptop bag or carrier, a backpack, a suitcase, a handbag, a messenger bag, or a briefcase.
