ELASTICALLY AVERAGED ALIGNMENT SYSTEMS AND METHODS
In one aspect an elastically averaged alignment system is provided. The alignment system includes a first component comprising an inner wall defining an alignment aperture, a second component including a receiving aperture, and a fastener configured for insertion into the alignment aperture and the receiving aperture to couple the first and second components. The system further includes an elastically deformable collar inserted onto the fastener. The collar is configured to elastically deform against the inner wall to an elastically averaged final configuration upon insertion into the alignment aperture, thereby coupling the first and second components to facilitate aligning the first component and the second component in a desired orientation.
1 . An elastically averaged alignment system comprising:
a first component comprising an inner wall defining an alignment aperture;
a second component comprising a receiving aperture;
a fastener configured for insertion into said alignment aperture and said receiving aperture to couple said first and second components; and
an elastically deformable collar inserted onto said fastener, said collar configured to elastically deform against said inner wall to an elastically averaged final configuration upon insertion into said alignment aperture, thereby coupling said first and second components to facilitate aligning said first component and said second component in a desired orientation.
2 . The system of claim 1 , wherein said elastically deformable collar is tapered.
3 . The system of claim 1 , wherein said elastically deformable collar is substantially conical or substantially pyramidal.
4 . The system of claim 1 , wherein said fastener comprises a head portion and a shank portion, said shank portion having a cross-section smaller than a cross-section of said alignment aperture.
5 . The system of claim 4 , wherein said fastener further comprises a first centerline and said alignment aperture comprises a second centerline, wherein when said fastener couples said first and second components, said elastically deformable collar elastically deforms against said alignment aperture inner wall to substantially align said first centerline and said second centerline.
6 . The system of claim 1 , wherein said receiving aperture is threaded, said fastener configured with complementary threads to couple said first and second components by threading into said threaded receiving aperture.
7 . The system of claim 1 , wherein said collar comprises a collar portion, a plurality of arms extending from said collar portion, and a biasing arm extending from each of said arms, wherein said biasing arms are configured to elastically deform against said alignment aperture inner wall when said fastener couples said first and second components.
8 . The system of claim 7 , wherein at least a portion of said collar portion includes a lock washer structure to facilitate engagement between said fastener and said first component.
9 . A vehicle comprising:
a body; and
an elastically averaged alignment system integrally arranged within said body, said elastically averaged alignment system comprising:
a first component comprising an inner wall defining an alignment aperture;
a second component comprising a receiving aperture;
a fastener configured for insertion into said alignment aperture and said receiving aperture to couple said first and second components; and
an elastically deformable collar inserted onto said fastener, said collar configured to elastically deform against said inner wall to an elastically averaged final configuration upon insertion into said alignment aperture, thereby coupling said first and second components to facilitate aligning said first component and said second component in a desired orientation.
10 . The vehicle of claim 9 , wherein said elastically deformable collar is substantially conical or substantially pyramidal.
11 . The vehicle of claim 9 , wherein said fastener comprises a head portion and a shank portion, said shank portion having a cross-section smaller than a cross-section of said alignment aperture.
12 . The vehicle of claim 11 , wherein said fastener further comprises a first centerline and said alignment aperture comprises a second centerline, wherein when said fastener couples said first and second components, said elastically deformable collar elastically deforms against said alignment aperture inner wall to substantially align said first centerline and said second centerline.
13 . The vehicle of claim 9 , wherein said collar comprises a collar portion, a plurality of arms extending from said collar portion, and a biasing arm extending from each of said arms, wherein said biasing arms are configured to elastically deform when said fastener couples said first and second components.
14 . The vehicle of claim 9 , wherein said first component is a side mirror and said body comprises said second component.
