Abstract

A releasable adhesive system for joining a first surface to a second surface. The system includes a primary material having a first portion including at least one first-portion molecule configured to be positioned parallel with at least one first-surface molecule of the first surface, and a second portion, opposite the first portion, including at least one second-portion molecule configured to be positioned parallel with at least second surfaced one molecule of the second surface. The first surface molecule, positioned parallel with the first-surface molecule, is configured to maintain bonds between the first portion and the first surface up to one or more pre-determined three scenarios, such as pre-determined shear, pull, and peel forces being exerted on the first surface. The second portion can function similarly with respect to the second surface.

First claim

What is claimed is:

1. A releasable adhesive system, for joining a first surface to a second surface, comprising:
a primary material having (i) a first portion including at least one first-portion molecule configured to be positioned parallel with at least one first-surface molecule of the first surface, and (ii) a second portion, opposite the first portion, including at least one second-portion molecule configured to be positioned parallel with at least one second-surface molecule of the second surface, wherein:
the primary material is shaped into a plurality of components, each component being positioned at a location and extending in a single direction outward from the location and forming a generally flat surface opposite the location, the plurality of components forming a plurality of independent bonds with the first surface at the generally flat surfaces, and
the first-portion molecule, positioned parallel with the first-surface molecule, is configured to (a) maintain a bond between the first portion and the first surface up to a pre-determined shear force being exerted on the first surface and (b) release the bond between the first portion and the first surface in response to at least a pre-determined peel force exerted on the first surface.

2. The releasable adhesive system of claim 1 , wherein the second-portion molecule, when positioned parallel with the second-surface molecule, is configured to:
maintain a bond between the second portion and the second surface up to a pre-determined shear force being exerted on the second surface; and
release the bond between the second portion and the second surface in response to a pre-determined peel force exerted on the second surface.

3. The releasable adhesive system of claim 1 , wherein the primary material includes ventilation holes allowing passage of gas and fumes through the first portion or the second portion.

4. The releasable adhesive system of claim 1 , wherein the first surface is permanently jointed to the second surfaces by fastening at least a section of the first surface to at least a section of the second surface.

5. A releasable adhesive system, for joining a first surface to a second surface, comprising:
a primary material having (i) a first portion including at least one first-portion molecule configured to be positioned parallel with at least one first-surface molecule of the first surface, and (ii) a second portion, opposite the first portion, including at least one second-portion molecule configured to be positioned parallel with at least one second-surface molecule of the second surface, wherein:
the primary material is shaped into a plurality of components, each component being positioned at a location and extending in a single direction outward from the location and forming a bonding surface generally parallel to and opposite the location, the plurality of components forming a plurality of independent bonds with the first surface at the bonding surface, and
the first-portion molecule, positioned parallel with the first-surface molecule, is configured to (a) maintain a bond between the first portion and the first surface up to a pre-determined shear force being exerted on the first surface and (b) release the bond between the first portion and the first surface in response to at least a pre-determined peel force exerted on the first surface.

6. The releasable adhesive system of claim 5 , wherein the second-portion molecule, when positioned parallel with the second-surface molecule, is configured to: maintain a bond between the second portion and the second surface up to a pre-determined shear force being exerted on the second surface; and
release the bond between the second portion and the second surface in response to a pre-determined peel force exerted on the second surface.

7. The releasable adhesive system of claim 5 , wherein the primary material includes ventilation holes allowing passage of gas and fumes through the first portion or the second portion.

8. The releasable adhesive system of claim 5 , wherein the first surface is permanently jointed to the second surfaces by fastening at least a section of the first surface to at least a section of the second surface.
