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 a corner portion of an interspatial area, the interspatial area between the perimeter of the inner frame and the perimeter of the outer frame; and

a skin covering the interspatial area and coupling the inner frame with the outer frame;

wherein the first plurality of braces allows the inner frame to move relative to the outer frame in an x-axis direction and in a y-axis direction; and

wherein the skin isolates the inner frame and the outer frame in a z-axis direction.

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, further comprising a second plurality of braces located in a side portion of the interspatial area.

5. The system of claim 4, 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.

6. The system of claim 1, wherein the first plurality of braces are shaped as trapezoids.

7. The system of claim 1, wherein the first plurality of braces are shaped as I-beams.

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

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

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

11. 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 component of the information handling system assembled in the inner frame; and

a skin covering the interspatial area and coupling the inner frame with the outer frame;

wherein the first plurality of braces allows the inner frame to move relative to the outer frame in an x-axis direction and in a y-axis direction; and

wherein the skin isolates the inner frame and the outer frame in a z-axis direction.

12. The system of claim 11, wherein the first plurality of braces includes a separation space between adjacent braces.

13. The system of claim 12, wherein the separation space between each adjacent brace is approximately equal.

14. The system of claim 11, further comprising 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.

15. The system of claim 14, 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.

16. The system of claim 11, wherein the first plurality of braces are shaped as trapezoids.

17. The system of claim 11, wherein the first plurality of braces are shaped as I-beams.

18. The system of claim 11, wherein the first plurality of braces are constructed of thermoplastic elastomer material.

19. The system of claim 11, wherein the configuration of the first plurality of braces is based on a dynamic modulus.

20. The system of claim 11, wherein the interspatial area has a consistent thickness.
