Transforming Chair

Process

People who live in smaller spaces can find it challenging to find room for furniture for themselves and for their pets. In addition to that, there are not many pieces of furniture that are versatile enough to be used for either people or animals. The Transforming Chair is a versatile piece of furniture that provides an elegant solution to this problem by morphing between two states: a papasan chair for humans and a dog bed for dogs.

The Transforming Chair was inspired by three primary precedents: a spiderwed, the Hoberman Sphere, and the Papasan Chair. The Hoberman sphere is a popular kids toy that expands to three times it's size and the Papasan Chair is a comfortable spherical chair. We began our process by examining different mechanisms for an expanding and contracting chair. 

 

Iteration One

Our first iteration began with an inner and outer ring that were connected with stretchy string. We've been inspired throughout this process by that design because it had an elegant look to it. However, because it was essentially just one ring suspended in air, it wasn't a plausible design. Therefore, we have used that idea and tried to create something that looked like that but actually worked. 

 

Iteration Two

Our second iteration is when we worked the design of the Hoberman Sphere into our chair. We used the ring of the Hoberman sphere as the outside of our chair and connect that to a stationary base. The initial connection pieces where two pieces of wood with a joint. These connection mechanisms didn't allow for the proper rotation of the sphere so we needed to create another kind of mechanism that accounted for that. We tried added three other joints to the connections but that still didn't account for the geometry of the ring.

 

Iteration Three

The third iteration included the rings of the Hoberman Sphere as our attachment mechanisms. We attached that all to a small stationary base. This was the closest interation we came to it acting like a chair. 

 

Iteration Four

In our fourth iteration we scaled our model up so that it came closer to the size of a chair. We also cut holes in our pieces so we could attach string throughout the model to simulate the seat of a chair. This model was pretty successful. However, we were not able to design rivets that were successful enough to create the legs of the chair.

 

Rivets

Throughout this process we went through eighteen iterations of rivets. These rivets were were we used as connecting joints for the Hoberman pieces. We encountered many issues with our rivets because they would expand when we printed out many of them at a time. Also, some were too weak. We also printed them on the Form II printer. This printer was good because it didn't allow any expansion. However, the resin material was too strong for a rivet.

Final (Brief)

People who live in smaller spaces can find it challenging to find room for furniture for themselves and for their pets. In addition to that, there are not many pieces of furniture that are versatile enough to be used for either people or animals. The Transforming Chair is a versatile piece of furniture that provides an elegant solution to this problem by morphing between two states: a papasan chair for humans and a dog bed for dogs.


The Transforming Chair was inspired by a combination of the Hoberman Sphere and the Papasan Chair. The Hoberman Sphere is a toy ball that can expand to three times it's size and the Papasan chair is a comfortable bowl shaped chair. The Transforming chair expands and contracts using the mechanism popularized in the Hoberman’s Sphere. This  allows the chair to expand, from a small chair, for the pet, into a papasan chair, for the human. This also saves space in the homes of users, as the chair can be stored in the smaller phase.

The chair will be comprised of an outer expanding ring conntected to four expanding half rings that attach to a stationary base. When completely contracted a pillow can be placed on the contracted chair for a dog to sit on. When expanded it will be a Papasan chair for people to sit on.
