Abstract

In one aspect, a component for an elastically averaged alignment system is provided. The component includes a body, an inner wall formed in the body and defining an alignment aperture, and an alignment member. The alignment member includes a pair of tabs extending from the body, and the alignment member is an elastically deformable material such that when the alignment member is inserted into another alignment aperture of another component, the alignment member elastically deforms to an elastically averaged configuration to facilitate aligning the component relative to the another component of the elastically averaged alignment system. The alignment aperture is configured to receive another alignment member of another component of the elastically averaged alignment system.

First claim

What is claimed is:

1. An elastically averaged alignment system comprising:
a first component and a second component, each of the first and second components having substantially a same construction and comprising:
a body;
an inner wall formed in the body and defining an alignment aperture; and
an alignment member comprising a pair of tabs extending from the body, wherein the alignment member is an elastically deformable material such that when the first component alignment member is inserted into the second component alignment aperture, the first component alignment member elastically deforms to an elastically averaged configuration to facilitate aligning and stacking the first component relative to the second component;
wherein the system further comprises:
a third component absent the pair of tabs of the alignment member, the third component comprising a body and an inner wall defining an alignment aperture, wherein when the second component alignment member is inserted into the third component alignment aperture, wherein the second component alignment member elastically deforms to an elastically averaged final configuration to facilitate aligning and stacking the second and third components in a defined orientation.

2. The system of claim 1 , wherein the second component alignment member comprises an outer wall having a retention feature configured to engage the third component inner wall and facilitate preventing the second component alignment member from being removed from the third component alignment aperture after insertion therein, wherein the retention feature comprises at least one of a rib extending from the outer wall and a notch formed in the outer wall.

3. The system of claim 1 , further comprising a battery carried by at least one of the first and second components.

4. The system of claim 1 , wherein the first component comprises more than one of the elastically deformable alignment member and the second component comprises more than one of the alignment aperture, the more than one elastically deformable alignment member being geometrically distributed with respect to respective ones of the more than one alignment apertures, such that portions of the elastically deformable alignment member of respective ones of the more than one elastically deformable alignment members, elastically deform to an elastically averaged final configuration that further aligns the first component and the second component in at least two of four planar orthogonal directions.

5. A method of manufacturing an elastically averaged alignment system, the method comprising:
forming a first and a second component each having substantially a same construction and comprising a body, an inner wall formed in the body and defining an alignment aperture, and an alignment member having a pair of tabs extending from the body;
forming the alignment members from an elastically deformable material such that when the first component alignment member is inserted into the second component alignment aperture, the first component alignment aperture elastically deforms to an elastically averaged configuration to facilitate aligning and stacking the first component relative to the second component; and
forming a third component absent the pair of tabs of the alignment member, the third component comprising an inner wall defining an alignment aperture, wherein when the second component alignment member is inserted into the third component alignment aperture, the second component alignment aperture elastically deforms to an elastically averaged configuration to facilitate aligning and stacking the second component and the third component.

6. The method of claim 5 , further comprising coupling a battery to at least one of the first component and the second component.

7. The method of claim 5 , further comprising forming the pair of tabs on opposed edges of the alignment aperture such that the pair of tabs are angled inward toward each other and extend at least partially over the alignment aperture.
