Abstract

A surface treatment support structure assembly for treating a contoured surface includes a support structure array formed from a plurality of base structures, each base structure being operably coupled with respect to one another and configured to slide along a longitudinal axis and rotate about a laterally translating axis which is perpendicular to the longitudinal axis. The support structure array further includes at least one applicator head coupled to each base structure of the support structure array, each of the at least one applicator head being configured to treat the contoured surface. Additionally, a base structure actuator is operatively coupled to and configured to manipulate each base structure along the longitudinal axis and the laterally translating axis such that the support structure array is adjusted relative to the contoured surface.

First claim

What is claimed is:

1. A surface treatment support structure assembly for treating a contoured surface, the surface treatment support structure assembly comprising:
a support structure array formed from a plurality of base structures with respective base structure actuators partially disposed within each respective base structure, a first base structure in the plurality of base structures being coupled via a first base structure actuator to a second base structure in the plurality of base structures and configured to slide along a longitudinal axis formed along a portion of the first base structure and rotate about a laterally translating axis perpendicular to the longitudinal axis responsive to actuation from the first base structure actuator, the first base structure is individually adjustable from the second base structure;
at least one applicator head coupled to each base structure of the support structure array, each of the at least one applicator head being configured to treat the contoured surface; and
the plurality of base structure actuators, with at least one base structure actuator in the plurality of base structure actuators operatively coupled to and configured to manipulate a respective base structure in the plurality of base structures along the longitudinal axis and the laterally translating axis such that the base structures forming the support structure array are individually adjusted relative to the contoured surface.

2. The surface treatment support structure assembly of claim 1 , wherein the support structure array is operatively coupled to a first attachment arm and a second attachment arm, and the first and second attachment arms further include an attachment arm actuator that is manipulated to adjust the support structure array between a first contoured shape and a second contoured shape.

3. The surface treatment support structure assembly of claim 2 , wherein the first contoured shape comprises a first radius and the second contoured shape comprises a second radius.

4. The surface treatment support structure assembly of claim 2 , wherein the first attachment arm comprises a first base structure joint and the second attachment arm comprises a second base structure joint, and each of the first and second base structure joints being rotatably coupled to the support structure array and configured to respectively rotate about a first attachment arm axis, a first base structure joint axis, a second attachment arm axis, and a second base structure joint axis.

5. The surface treatment support structure assembly of claim 4 , wherein the first attachment arm further comprises a first attachment pillar joint and the second attachment arm further comprises a second attachment pillar joint, and each of the first and second pillar joints is rotatably attached to a support pillar and configured to rotate about the respective first and second attachment arm axes.

6. The surface treatment support structure assembly of claim 2 , further comprising a sensor coupled to each base structure configured to detect an existing shape of the contoured surface and generate a contoured data set.

7. The surface treatment support structure assembly of claim 6 , further comprising a controller communicably coupled to the sensor, the base structure actuator and the attachment arm actuator, wherein the controller is programmed to receive a signal from the sensor and control the base structure actuator and the attachment arm actuator to manipulate the support structure array based on the contoured data set.

8. The surface treatment support structure assembly of claim 1 , wherein the at least one applicator head comprises one of an abrasion head, an inspection head, a heater, an UV emitter, a spray nozzle, and an inkjet printing head configured to apply a surface treatment to the contoured surface.

9. A method of treating a contoured surface with a surface treatment support structure assembly, the method comprising:
forming a support structure array from a plurality of base structures with respective base structure actuators partially disposed within each respective base structure, a first base structure in the plurality of base structures being coupled via a first base structure actuator to a second base structure in the plurality of base structures and configured to slide along a longitudinal axis formed along a portion of the first base structure and rotate about a laterally translating axis which is perpendicular to the longitudinal axis responsive to actuation from the first base structure actuator, the first base structure individually adjustable from the second base structure;
coupling at least one applicator head to each base structure of the support structure array, each of the at least one applicator head configured to treat the contoured surface; and
coupling the plurality of base structure actuators to the plurality of base structures, with at least one base structure actuator in the plurality of base structure actuators operatively coupled and configured to manipulate a respective base structure along the longitudinal axis and the laterally translating axis such that the base structures forming the support structure array are individually adjusted relative to the contoured surface.

10. The method of claim 9 , wherein the support structure array is operatively coupled to a first attachment arm and a second attachment arm, and adjusting the support structure array comprises activating an attachment arm actuator to adjust the support structure array between a first contoured shape and a second contoured shape.

11. The method of claim 10 , wherein adjusting the support, structure array between the first contoured shape and the second contoured shape comprises adjusting between a first radius and a second radius.

12. The method of claim 10 , wherein the first attachment arm comprises a first base structure joint and the second attachment arm comprises a second base structure joint and each of the first and second base structure joints are rotatably coupled to the support structure array, and adjusting the support structure array comprises respectively rotating the first and second attachment arms about a first attachment arm axis, a first base structure joint axis, a second attachment arm axis, and a second base structure joint axis.

13. The method of claim 12 , wherein the first attachment arm further comprises a first attachment pillar joint rotatably attached to a support pillar and the second attachment arm further comprises a second attachment pillar joint rotatably attached to the support pillar, and adjusting the support structure array further comprises rotating the first and second attachment pillar joints about the respective first and second attachment arm axes.

14. The method of claim 10 , further comprising a sensor coupled to each base structure and manipulating each base structure includes the sensor detecting an existing shape of the contoured surface and generating a contoured data set.

15. The method of claim 14 , further comprising a controller communicably coupled to the sensor, the base structure actuator, and the attachment arm actuator, and manipulating the support structure array comprises programming the controller to receive a signal from the sensor and controlling the base structure actuator and the attachment arm actuator to manipulate the support structure array based on the contoured data set.

16. The method of claim 9 , wherein coupling the at least, one applicator head to the base structure comprises one of an abrasion head, an inspection head, a heater, an UV emitter, a spray nozzle,
