Abstract

A node may be additively manufactured. The node may include a first surface and a second surface, and the second surface may bound a recess of the node. A structure may be inserted into the recess. A sealing member extend away from the second surface and contact the structure, such that a sealed space may be created between the node and the structure. An adhesive may be applied in the sealed space to at least partially attach the structure to the node.

First claim

What is claimed is:

1. An apparatus comprising:
an additively manufactured node including:
a first surface;
a second surface opposite the first surface;
a third surface non-parallel to the second surface, wherein the second surface and the third surface bound a recess in the node;
a body separating the first surface from the second surface; and
a channel formed within the body separating the first surface from the second surface, wherein the channel extends through the body from the first surface to the second surface, and wherein the channel is configured to carry an injected substance from the first surface to the second surface; and

a seal member including:
a first flap with a first proximal end and a first distal end, the first proximal end attached to the second surface at a first attachment point, wherein the first flap is configured to shift about the first attachment point in response to pressure applied by the injected substance; and
a second flap defined by a second proximal end and a second distal end, the second proximal end attached to the second surface at a second attachment point, the second flap being arranged opposing the first flap with the second distal end of the second flap overlapping the first distal end of the first flap, such that the second flap shifts about the second attachment point in response to contact made by the first distal end with the second distal end, wherein the contact made by the first distal end is made in response to the pressure applied by a structure inserted in the recess.

2. The apparatus of claim 1 , wherein the channel comprises a first channel portion and a second channel portion, the first channel portion extending into the body of the additively manufactured node from the first surface, the second channel portion extending into the body from the second surface, wherein the first channel portion meets the second channel portion in the body, and wherein the second channel portion is greater in size than the first channel portion in at least one dimension.

3. An apparatus comprising:
an additively manufactured node including:
a first surface;
a second surface opposite the first surface;
a third surface non-parallel to the second surface, wherein the second surface and the third surface bound a recess in the node;
a body separating the first surface from the second surface; and
a channel formed within the body separating the first surface from the second surface, wherein the channel extends through the body from the first surface to the second surface, and wherein the channel is configured to carry an injected substance from the first surface to the second surface; and

a seal member including:
a first flap with a first proximal end and a first distal end, the first proximal end attached to the second surface at a first attachment point, wherein the first flap is configured to shift about the first attachment point in response to pressure applied by the injected substance, and wherein the first flap includes an outer surface that faces away from the second surface; and
a sealant bead arranged on the outer surface of the first flap.

4. The apparatus of claim 3 , wherein the channel comprises a first channel portion and a second channel portion, the first channel portion extending into the body of the additively manufactured node from the first surface, the second channel portion extending into the body from the second surface, wherein the first channel portion meets the second channel portion in the body, and wherein the second channel portion is greater in size than the first channel portion in at least one dimension.

5. An apparatus comprising:
an injected substance;
an additively manufactured node including:
a first surface;
a second surface opposite the first surface;
a third surface non-parallel to the second surface, wherein the second surface and the third surface bound a recess in the node;
a body separating the first surface from the second surface; and
a channel formed within the body separating the first surface from the second surface, wherein the channel extends through the body from the first surface to the second surface, wherein the channel is configured to carry the injected substance from the first surface to the second surface, and wherein the injected substance includes an adhesive that adheres the second surface to the portion of the structure;

a seal member including a first flap with a first proximal end and a first distal end, the first proximal end attached to the second surface at a first attachment point, wherein the first flap comprises an outer surface that faces away from the second surface, and wherein the seal member further including a sealant bead arranged on the outer surface of the flap;
a structure inserted in the recess, such that a portion of the structure is seated within the recess, and the second surface and the third surface surround the portion of the structure, wherein the seal member is arranged between the second surface and the portion of the structure such that the seal member provides a seal between the second surface and the portion of the structure.

6. The apparatus of claim 5 , wherein the structure includes one or more tubes.

7. The apparatus of claim 5 , wherein the seal member creates an enclosed, sealed space between the node and the portion of the structure, and wherein the second surface is configured to be adhered to the portion of the structure by an adhesive in the enclosed, sealed space.

8. The apparatus of claim 5 , wherein the channel comprises a first channel portion and a second channel portion, the first channel portion extending into the body of the additively manufactured node from the first surface, the second channel portion extending into the body from the second surface, wherein the first channel portion meets the second channel portion in the body, and wherein the second channel portion is greater in size than the first channel portion in at least one dimension.

9. An apparatus comprising:
an injected substance;
an additively manufactured node including:
a first surface;
a second surface opposite the first surface;
a third surface non-parallel to the second surface, wherein the second surface and the third surface bound a recess in the node;
a body separating the first surface from the second surface; and
a channel formed within the body separating the first surface from the second surface, wherein the channel extends through the body from the first surface to the second surface, and wherein the channel is configured to carry an injected substance from the first surface to the second surface; and

a structure inserted in the recess, such that a portion of the structure is seated within the recess, and the second surface and the third surface surround the portion of the structure, wherein the structure is defined by a third proximal end and a third distal end, wherein the portion of the structure comprises the third distal end, and wherein the third distal end of the structure is seated against the third surface of the node;
a seal member including a first flap with a first proximal end and a first distal end, the first proximal end attached to the second surface at a first attachment point, wherein the seal member is arranged between the second surface and the portion of the structure such that the seal member provides a seal between the second surface and the portion of the structure.

10. The apparatus of claim 7 , wherein the structure includes one or more tubes.

11. The apparatus of claim 7 , wherein the seal member creates an enclosed, sealed space between the node and the portion of the structure, and wherein the second surfac
