Abstract

An article includes a hollow enclosure defining a void. The void has a first section and a second section separate from the first section. An electronic component is housed in the first section and the second section of the void. A low pressure mold material is molded into the first section of the void and cured around a first segment of the electronic component to encapsulate the first segment of the electronic component. A support seal is inserted into the second section of the void adjacent a second segment of the electronic component. The support seal defines a sealing barrier on one side of the low pressure mold material that limits the flow of low pressure mold material out of the first section of the void.

First claim

What is claimed:

1. An article comprising:
an eyewear frame having a hollow enclosure defining a void, the void having a first section and a second section;
an electronic component contained in the first section and the second section of the void;
a low pressure mold material molded into the first section of the void and cured around a first segment of the electronic component to encapsulate the first segment of the electronic component and secure the first segment of the electronic component to the hollow enclosure of the eyewear frame; and
an open space having no low pressure mold material located in the second section of the void, the open space at least partially surrounding a second segment of the electronic component extending from the first segment of the electronic component, wherein a lateral surface of the low pressure mold material faces and is adjacent to the open space.

2. The article of claim 1 , wherein at least a portion of the open space comprises a shape corresponding to a removable support seal.

3. The article of claim 1 , wherein the lateral surface of the low pressure mold material comprises a shape defined by a geometry of a removable support seal.

4. The article of claim 1 , wherein the open space fully surrounds the second segment of the electronic component.

5. The article of claim 1 , wherein the open space only partially surrounds the second segment of the electronic component.

6. The article of claim 1 , wherein the second section of the void comprises a bottom wall, a first sidewall extending upwards from the bottom wall, and a second sidewall extending upwards from the bottom wall, wherein the first sidewall and the second sidewall diverge away from each other such that the second section of the void comprises a hollow wedge shape that narrows towards the bottom wall.

7. The article of claim 1 , wherein the second section of the void comprises a bottom wall, a first sidewall extending upwards from the bottom wall, and a second sidewall extending upwards from the bottom wall, wherein the second segment of the electronic component is spaced from the first sidewall and the second sidewall.

8. The article of claim 1 , wherein the electronic component comprises a flexible circuit board.

9. The article of claim 1 , further comprising a housing piece secured to the article to enclose the low pressure mold material and the open space.

10. An eyewear frame comprising:
a first aperture configured to support a first lens;
a second aperture configured to support a second lens;
a first void located above the first aperture and comprising a respective first section and a respective second section;
a first electronic component contained in the respective first section and the respective second section of the first void;
a first low pressure mold material molded into the respective first section of the first void and cured around a respective first segment of the first electronic component to encapsulate the respective first segment of the first electronic component; and
a first open space having no low pressure mold material located in the respective second section of the first void and at least partially surrounding a respective second segment of the first electronic component extending from the respective first segment of the first electronic component, wherein a respective lateral surface of the first low pressure mold material faces and is adjacent to the first open space.

11. The eyewear frame of claim 10 , further comprising:
a second void located above the second aperture and comprising a respective first section and a respective second section;
a second electronic component contained in the respective first section and the respective second section of the second void;
a second low pressure mold material molded into the respective first section of the second void and cured around a respective first segment of the second electronic component to encapsulate the respective first segment of the second electronic component; and
a second open space having no low pressure mold material located in the respective second section of the second void and at least partially surrounding a respective second segment of the second electronic component extending from the respective first segment of the second electronic component, wherein a respective lateral surface of the second low pressure mold material faces and is adjacent to the second open space.

12. The eyewear frame of claim 10 , wherein at least a portion of the first open space comprises a shape corresponding to a removable support seal.

13. The eyewear frame of claim 10 , wherein the respective lateral surface of the first low pressure mold material comprises a shape defined by a geometry of a removable support seal.

14. The eyewear frame of claim 10 , wherein the first open space fully surrounds the respective second segment of the first electronic component.

15. The eyewear frame of claim 10 , wherein the first open space only partially surrounds the respective second segment of the first electronic component.

16. The eyewear frame of claim 10 , wherein the first electronic component comprises a flexible circuit board.

17. The eyewear frame of claim 10 , further comprising a housing piece secured to enclose the first low pressure mold material and the first open space.

18. A method for use in forming augmented reality eyewear, the augmented reality eyewear including a frame having an aperture configured to support a lens and a void having a first section and a second section, the method comprising:
inserting an electronic component into the void, the electronic component having a first segment placed into the first section of the void, and a second segment placed in the second section of the void;
placing a support seal in the second section of the void such that the support seal supports and maintains at least the second segment of the electronic component in a fixed position in the void;
injecting a hot melt material into the first section of the void to encapsulate the first segment of the electronic component in the first section of the void, the support seal limiting the flow of the hot melt material into the second section of the void; and
removing the support seal from the second section of the void to define an open space in the second section of the void.

19. The method of claim 18 , further comprising:
inserting the frame into a low pressure mold prior to injecting the hot melt material into the first segment of the void;
opening the low pressure mold after injecting the hot melt material into the first segment of the void; and
removing the frame from the low pressure mold.

20. The method of claim 18 , further comprising securing a housing piece to the frame to enclose the hot melt material and the open space.
