INFLATION SYSTEM: DESIGN DETAILS

PHYSICAL SIGNS OF ANXIETY�� Increased heart beat/palpitations�� Sweating�� Breathlessness�� Muscle tension�� FearAnxiety occurs when personal space is violated. Discomfort from the invasion can quickly turn to anxiety depending on the proximity and extent of the violation, as well as the context of the occurence. The inflation system in our project will come to represent the fear associated with anxiety, by morphing the exterior form.

Koryo Miura, an astrophysicist, was responsible for the creation of the ‘miura fold’, which demonstrates an important example in the field of rigid RULJDPL��5LJLG�RULJDPL�LV�WKH�VWXG\�RI�IROGLQJ�HOHPHQWV�ZKLFK�XVH�ÁDW�ULJLG�VKHHWV�MRLQHG�E\�KLQJHV��7KH�0LXUD�IROG�KDV�EHHQ�XVHG�WR�SDFN�VRODU�SDQHOV�LQ�preparation for space missions, and this aspect of origami study has been responsible for solving everyday issues, such as folding airbags into steering wheels.

The Miura allows possibilities for a high ratio of folded to unfolded space, as the fold occurs in two directions. In other words, the Miura allows a paper surface to be packed into a very compact or minimal space, and by pulling two opposite corners, will easily unfold and transform. Likewise, it can be replaced into its folded form by simply pushing two corners towards each other.

INITIAL DESIGN DEVELOPMENT

Our design process has begun by attempting to LQWHJUDWH� LQÁDWLRQ�DQG�SDQHO�DQG� IROG� V\VWHPV� LQWR�RQH�design.

INTEGRATING SYSTEMS

design

Developing our idea, we decided to create a system which was far more flexible and integrate the transformability of folding systems with the more obvious transformability of inflation.

Therefore our object consists of 3 layers: a top ‘sk in’ of t ransformable folds, the interior inflation system which would lay dormant until inflated, and an underneath rigid layer which allows the piece to sit firmly against the body. Also, the ‘scar f’ became far more of a ‘cape’ concept, covering more of the body, though also maintain�ing the asymmetry as can be seen on the next page. The asymmetry responds directly to our pa�rameters which we then set for our design, also discussed on the following page.

CONCLUSION: At this stage, the fan system allow us to experiment to a greater extent, and though it is trickier to integrate into the whole, will provide a more prolonged experience of the object in action.

TECHNIQUE RESEARCH

design

Researching different fold techniques, we have created several miura fold prototypes, including this curved form above. We see huge potential for this fold and have proceeded to create a version of the pattern in Rhino with which to experiment and see how much we can change the pattern and still create a successful transformable fold.

The standard flat Miura fold above (centre) illustrates another principle discovered with protoyping: the Miura requires two points of push or pull to expand or retract the surface. 7KH�WZR�SRLQWV�FDQ�DOVR�EH�ZDUSHG�RU�SLQQHG�WR�FUHDWH�VKDSHV�ZKLFK�DGG�GHÁHFWLRQ�LQ�WKH�expansion trajectory.

We have to work out a way to create a closing geometry made of folds. Also, our original idea to create a slit or panel to encourage the inflation out of the folding system may in fact not work, as the inflation is more likely to push open at the weak connecting points, as was the case in this test. Therefore a closed geometry may solve both problems In our next test, we must try several types of openings and a proper inflation system.

TOP LEFT + RIGHTThese illustrate the potential for transformation, possible with additional folds being containt�ed in the space. This will add to the overall weight of the object and therefore require more air to push out the folds. However it also allows us the opportunity to create something as dramatic as our design concept requires.
