Abstract

A process of overmolding a frame of a portable eyewear electronic device and a frame produced by the process is presented. A frame that includes a first material and includes a releasably mountable feature is attached to the mold in a desired position and does not contact other areas of the mold. The mold is filled with a second material to at least partially encase the frame insert.

First claim

What is claimed is:

1. A process comprising:
providing an electronic eyewear device frame insert composed of a first material;
providing a mold for the electronic eyewear device frame insert, wherein the electronic eyewear device frame insert comprises a camera mount opening configured for releasable attachment to the mold which does not interfere with overmolding of areas of the electronic eyewear device frame insert not comprising the camera mount opening to allow overmolding of other areas of the electronic eyewear device frame insert;
inserting the electronic eyewear device frame insert into the mold and releasably attaching the camera mount opening of the electronic eyewear device frame insert to the mold and not contacting other areas of the mold;
filling the mold with a second material to cover the electronic eyewear device frame insert with a desired coating thickness, wherein the releasable attachment of the camera mount opening to the mold prevents overmolding of the camera mount opening; and
removing from the mold an electronic eyewear device having the electronic eyewear device frame insert partially encased by the second material to form an overmolded electronic eyewear device.

2. The process of claim 1 , further comprising assembling one or more parts to the electronic eyewear device frame insert prior to inserting the electronic eyewear device frame insert into the mold.

3. The process of claim 2 , wherein the one or more parts include a flexible printed circuit board (PCB) or antenna.

4. The process of claim 2 , wherein the one or more parts includes a decorative feature.

5. The process of claim 1 , wherein the first material has a Shore Hardness that is substantially identical to the second material.

6. The process of claim 1 , wherein the second material is different from the first material.

7. The process of claim 6 , wherein the second material has a lower Shore Hardness than the first material.

8. A process according to claim 7 , wherein the first material has a Shore D Hardness of between about 80 to about 85 and the second material has a Shore A hardness of between about 60 to about 70.

9. The process of claim 7 , wherein the second material is a rubber material.

10. The process of claim 1 , wherein the first material comprises a thermoplastic.

11. The process of claim 1 , wherein the first material is transparent.

12. The process of claim 1 , wherein the first material is a metal or metal composite.

13. The process of claim 1 , wherein the electronic eyewear device frame insert further comprises an eye lens rim configured for releasable attachment to the mold.

14. The process of claim 13 , wherein the eye lens rim comprises a groove.

15. The process of claim 1 , wherein the second material is opaque or translucent.

16. The process of claim 1 , wherein the mold is a horizontal injection molding machine.

17. An overmolded electronic eyewear device produced by the process of claim 1 .

18. The overmolded electronic eyewear device of claim 17 , wherein the overmolded electronic eyewear device comprises one or more parts at least partially encased by the second material.

19. The overmolded electronic eyewear device of claim 17 , wherein the second material has a lower Shore Hardness than the first material.

20. The overmolded electronic eyewear device of claim 19 , wherein the first material has a Shore D Hardness of between about 80 to about 85 and the second material has a Shore A hardness of between about 60 to about 70.
