Integrated fastener system
Disclosed are systems and methods for coupling a first component to a second component via an integrated fastener. The component assembly includes a first component having a first surface and a second surface. An integrated fastener extending from the second surface and configured to attach the first component adjacent to the second component. The first component and the integrated fastener are formed as a unitary structure using, for example, an additive manufacturing process. The integrated fastener can include a clip assembly with one or more retention features extending outwardly from the integrated fastener at an end opposite the first component.
1. A fastener for attaching a first component to a second component, the fastener comprising:
a body defining a central longitudinal axis; and
a clip assembly having three retention features resiliently coupled to the body and configured to retain the fastener relative to the second component via an opening in the second component,
wherein each of the three retention features is angled away from the central longitudinal axis and is configured to deflect inward toward the central longitudinal axis as the clip assembly is passed through the opening in the second component, and
wherein the three retention features are spaced about the central longitudinal axis from one another by 120 degrees.
2. The fastener of claim 1 , wherein each of the three retention features is coupled to the body at a distal end thereof.
3. The fastener of claim 1 , wherein the body and the clip assembly are fabricated as a unitary structure via an additive manufacturing technique.
4. The fastener of claim 1 , wherein each of the three retention features includes a return arm resiliently connected to the clip assembly and configured to deflect as the clip assembly is passed through an opening in the second component.
5. The fastener of claim 4 , wherein each of the three retention features comprises a concave recess formed in or on an interior surface of the return arm.
6. The fastener of claim 1 , wherein each of the three retention features is configured to engage the second component at the opening via a catch.
7. The fastener of claim 1 , wherein the body is a hollow cylinder and the three retention features extend from a sidewall thereof.
8. The fastener of claim 1 , wherein each of the three retention features comprises a plurality of fins distributed along the central longitudinal axis to define a fin tier.
9. The fastener of claim 1 , wherein each of the three retention features comprises a plurality of fins distributed along the central longitudinal axis to define a first fin tier and a second fin tier, wherein the first fin tier is offset relative to the second fin tier by a distance.
10. A fastener for attaching a first component to a second component, the fastener comprising:
a body defining a central longitudinal axis; and
a clip assembly having five retention features resiliently coupled to the body and configured to retain the fastener relative to the second component via an opening in the second component,
wherein each of the five retention features is angled away from the central longitudinal axis and is configured to deflect inward toward the central longitudinal axis as the clip assembly is passed through the opening in the second component, and
wherein the five retention features are spaced about the central longitudinal axis from one another by 72 degrees.
