Slide 1:

- We designed the Donut; an outdoor seat for both dogs and humans.

Slide 2:

- This image captures the bond between human and dog

Slide 3:

- Our project is a piece of outdoor furniture that allows dogs and humans to interact comfortably.

- Humans can sit on the seat part of the structure while dogs have the option to either sit in the center, or crawl through the hollow insides of the structure to lay down and get shade

Slide 4:

- Here is a bench that was cut with a CNC machine and is installed at Harvard.

-  There is usually a design technique associated with making structures using a CNC Machine

- This technique usually involves stacking shaped layers that morph so that when all the layers are put together, the structure looks like one solid structure.

Slide 5:

-This is another bench made with a CNC machine, however to connect all of the layers, they used dowels.

Slide 6:

- Here is a rocking chair that captures the same aspect of human and dog interaction as ours.  

- This chair also seems to aim for comfort with both the human and the dog

Slide 7:

- Here was one of the early sketches that we had

- We thought that this looked too worm-like, however is did capture the idea of both nature, a tunnel, and the piece of human and dog interaction.

Slide 8:

-  Our coach recommended a smaller size donut shaped structure

- We started taking measurements and dimensioning,

-This was made by using the sweep2 command in Rhino and sweeping an arch along 2 curves.

- The only problem with this was that there was no seat for the human to sit on.

-This also was too closed in

Slide 9:

- After making many iterations using a loft command, while changing one element of the structure each time (i.e.. ellipse diameter, height, etc.), we decided on the fourth iteration because it was rather short, so it seemed to make nice open space to sit in.

- The opening to the center of the structure was also wide so that the structure could feel less closed

Slide 10:

- This is one of he ways we tried to make the seat for the project.

- We tried to loft the seat so that we could use the booleanDifference command to cut the seat out of the rest of the structure

- Using the loft command proved to create imperfections in the seat object that we would use to subtract from the larger structure

- We needed the structure and the lofted seat to line up perfectly.

Slide 11:

- This was how we thought we would make the structure stable

- We thought that we would have horizontal arches that notched into the vertical arches

Slide 12:

- This is the final iteration called "The Donut"

- Here, we made the seat by making the its curves part of the arches that became lofted to make the structure.  This way both the seat and the rest of the structure were made at the same time.

- One can also tell that we decided to cut the object into layers from bottom to top instead of having morphing arches around an ellipse.  The reason we did this was because the original method, when imported into the cutting software 123D Make, created too many errors, making it the original assembly method unachievable.

-There is also spacing between the layers below the seat so that the tunnel is less daunting and scary for the dog to go through or into.  The reason this helps is because it lets light into the space.

Slide 13:

- Here one can see that the components of the Donut are: humans sitting, gardens and nature, and human and dg interaction.

Slide 14:

- These are the uses of the Donut.

- As you can see there are many uses for the Donut some of which include plain sitting and resting, and some of which include a dog going into the tunnel of the Donut for shade.

Slide 15:

- Here is an assembly diagram showing how the pieces stack together

Slide 16:

- Here is a GIF, animating how the pieces stack together
