Abstract

Methods and systems are disclosed for internal shock isolation in an information handling system. The method includes directing a tool to mold an outer frame of an information handling system, and directing the tool to mold an inner frame of the information handling system. The inner frame has a perimeter less than the perimeter of the outer frame. The method further includes directing the tool to construct a first plurality of braces in an interspatial area. The interspatial area is between the perimeter of the inner frame and the perimeter of the outer frame.

Claims

1. An internal isolation system comprising:

an outer frame of an information handling system;

an inner frame of the information handling system, the inner frame having a perimeter less than the perimeter of the outer frame;

a first plurality of braces in an interspatial area, the interspatial area between the perimeter of the inner frame and the perimeter of the outer frame; and

a second plurality of braces in the interspatial area, wherein the first plurality of braces are located in a corner portion of the interspatial area and the second plurality of braces are located in a side portion of the interspatial area.

2. The system of claim 1, wherein the first plurality of braces includes a separation space between adjacent braces.

3. The system of claim 2, wherein the separation space between each adjacent brace is approximately equal.

4. The system of claim 1, wherein the first plurality of braces includes a first separation space between adjacent braces;

the second plurality of braces includes a second separation space between adjacent braces, and the first separation space is less than the second separation space.

5. The system of claim 1, wherein the first plurality of braces are constructed of thermoplastic elastomer material.

6. The system of claim 1, wherein the configuration of the first plurality of braces is based on a dynamic modulus.

7. The system of claim 1, wherein the interspatial area has a consistent thickness.

8. The system of claim 1, An internal isolation system comprising:

an outer frame of an information handling system;

an inner frame of the information handling system, the inner frame having a perimeter less than the perimeter of the outer frame; and

a first plurality of braces in an interspatial area, the interspatial area between the perimeter of the inner frame and the perimeter of the outer frame, wherein the first plurality of braces are I-beams, shaped as trapezoids.

9. An internal isolation system comprising:

an outer frame of an information handling system;

an inner frame of the information handling system, the inner frame having a perimeter less than the perimeter of the outer frame;

a first plurality of braces in an interspatial area, the interspatial area between the perimeter of the inner frame and the perimeter of the outer frame; and

a plurality of components of the information handling system assembled in the inner frame.
