Component assembly cushioning device for mobile devices
View Patent ↗A spacer for use in a mobile device fills the space between a component assembly and a housing. The spacer includes a layer of compressible material for insertion between the component assembly and the housing. A plurality of compressible features are provided on a face of the layer. Upon insertion of the component assembly and assembly of the housing, the compressible features are compressed to fill a gap between the component assembly and the housing without over-compressing the main body of the spacer, allowing the body of the spacer to cushion any subsequent impact to the mobile device.
1. A spacer for use in a mobile device, the spacer for filling a space between a component assembly and a housing, the component assembly including a display component, the spacer comprising:
a layer of compressible material for insertion between the component assembly and the housing; and
a plurality of compressible features integrally formed on a face of the layer, the compressible features being compressible, via volumetric pressure difference, upon assembly of the mobile device and extending between the component assembly and the housing to space the component assembly inside the housing when the mobile device is assembled, and the depth of the layer and uncompressed compressible features exceeding the depth of the space between the component assembly and the housing, and the depth of the compressed layer and the compressed compressible features exceeding a predetermined critical depth;
wherein the compressible material is a compressible foam.
2. The spacer of claim 1 , wherein the compressible features are domed, cylindrical, polygonal prism, conical, frusto-conical, pyramidal or frusto-pyramidal in shape.
3. The spacer of claim 1 , wherein the compressible features are uniform in depth.
4. The spacer of claim 1 , wherein the compressible features are clustered in spaced apart groupings.
5. The spacer of claim 1 , wherein the layer is provided with an aperture to expose the display component.
6. The spacer of claim 5 , wherein the display component is one of: a liquid crystal display, a plasma display, a light emitting diode display and an organic display.
7. The spacer of claim 1 , wherein the compressible features form a grid pattern.
