Abstract

An automated system for automatically mixing and verifying paint is described. The system may include a kiosk configured to automatically add a paint of a second color to a paint container holding a first color of paint so as to produce a requested third color of paint. The system may further verify that the mixed paint color is the requested paint color using a laser to perform verification.

Claims

1. A paint color mixing system, the system comprising:

a processing device equipped with a processor;

a paint container including an aperture, the paint container containing a paint of a first color;

a self-service kiosk in communication with the processing device and including an interactive display, a nozzle and a laser, the kiosk configured to;

support the paint container by inserting the nozzle into the aperture of the paint container;

inject a paint of a second color into the paint container through the nozzle so as to attempt to produce a paint of a third color, the third color requested by a user via the interactive display;

mix the paint of the second color with the paint of the first color in the paint container;

project a transmission from the laser through the aperture into the paint container to determine a color of the mixed paint inside the paint container, the paint container remaining in a sealed condition during the transmission,

wherein the processing device is configured to;

verify programmatically whether the determined color of the mixed paint in the paint container is the same as the paint of the third color and,

transmit a result of the verifying to the interactive display.

2. The system of claim 1, wherein the aperture is located in a lid on the top of the paint container.

3. The system of claim 1, wherein the aperture is on at least a first side of the paint container.

4. The system of claim 1, wherein the laser is used to perform Near-Infrared Spectroscopy (NIRS) to determine the color of the mixed paint.

5. The system of claim 1, wherein the paint container is a spray paint can.

6. The system of claim 1, wherein the kiosk is further configured to:

receive a request for a paint additive via the interactive display.

7. The system of claim 6, wherein the kiosk is further configured to:

select the paint of the second color based on requested paint of the third color and the requested paint additive.

8. The system of claim 1, wherein the processing device determines that at least one of more paint and a different color of paint is needed to produce the paint of the third color.

9. The system of claim 1, wherein the kiosk is further configured to:

remove automatically the paint container from a housing in the kiosk in response to the processing device verifying that the determined color of the mixed paint in the paint container is the same as the paint of the third color requested by the user.

10. A paint color mixing method performed in a self-service paint mixing kiosk equipped with an interactive display, a nozzle and a laser, the method comprising:

providing a paint container that includes an aperture and contains a paint of a first color;

inserting the nozzle into the aperture of the paint container, the nozzle providing support for the paint container in the kiosk;

injecting a paint of a second color into the paint container through the nozzle so as to attempt to produce a paint of a third color, the third color requested by a user via the interactive display;

mixing the paint of the second color with the paint of the first color in the paint container;

projecting a transmission from the laser through the aperture into the paint container to determine a color of the mixed paint inside the paint container, the paint container remaining in a sealed condition during the transmission;

verifying, via a processing device in communication with the kiosk whether the determined color of the mixed paint in the paint container is the same as the paint of the third color; and

transmitting a result of the verifying to the interactive display.

11. The method of claim 10, wherein the aperture is located in a lid on the top of the paint container.

12. The method of claim 10, wherein the aperture is located on at least a first side of the paint container.

13. The method of claim 10, wherein laser is used to perform Near-Infrared Spectroscopy (NIRS) to determine the color of the mixed paint.

14. The method of claim 10, wherein the paint container is a spray paint can.

15. The method of claim 10, further comprising:

receiving a request on the interactive display of the kiosk for a paint additive.

16. The method of claim 15, further comprising:

selecting programmatically, at the kiosk, the paint of the second color based on the requested third color and the requested paint additive.

17. The method of claim 10, further comprising:

determining, with the processing device, that at least one of more paint and a different color of paint is needed to produce the paint of the third color.

18. The method of claim 10, further comprising:

removing automatically the paint container from a housing in the self-service kiosk in response to the processing device verifying that the determined color of the mixed paint in the paint container is the same as the paint of the third color requested by the user.

19. A paint color verification system, the system comprising:

a processing device equipped with a processor;

a paint container including an aperture, the paint container containing a paint;

a structural device in communication with the processing device and including an interactive display, a nozzle and a laser, the structural device configured to;

support the paint container by inserting the nozzle into the aperture of the paint container; and

project a transmission from the laser through the aperture into the paint container to determine a color of the paint inside the paint container, the paint container remaining in a sealed condition during the transmission,

wherein the processing device is configured to;

receive a request to determine whether the color of the paint in the paint container is a first color;

verify programmatically whether the determined color of the paint in the paint container is the same as the second color; and

transmit the verification.

20. A paint color verification system of claim 19, wherein the laser is used to perform Near-Infrared Spectroscopy (NIRS) to determine the color of the paint in the paint container.
