Prototyping/Cochlea full scale prototype

The construction of the full scale prototype was a challenging and informative process. It was important to be created in full scale so it would be possible to deploy it and test its design and discover any practical issues.

The material that was chosen to be used was concrete. Concrete was chosen due to its characteristics of being a strong and long lasting material. Concrete is ideal as a material for outdoor furniture because it has a very low cost of maintenance. Also it one of the main materials of the urban environment. It would be a challenge to create a natural and thin form out of a material that usually used to construct buildings and other heavy structures.

The full scale prototype was made by creating a polystyrene skeleton of the indented shape and then adding cement and concrete filler to the outside surface in order to give the feeling of a concrete structure. The intention was to create a similar to the final visual result without the weight of an actual concrete structure which would made the deployment afterwards much more difficult.

In the beginning the bench consisted of two parts, the sitting part and the upper part. In order to bond these two pieces together, the inside surface was coated from top to bottom with two layers of fibreglass (300 gsm). After the process of the fibreglass, the inside surface was covered with plaster and painted white in order to create a difference with the outside colour of the concrete surface. The sitting part was added and bolted on the concrete surface and the deployment started.

Prototyping/Headphones concept

Exploring the idea of the sea shell and the sound that can be heard when you put it by your ear. I decided to  create a prototype of headphones (non working) in which the earmuffs would resemble the form and shape of a seashell. The concept behind this prototype was the idea of having the sound of the sea by your ears while you are walking within the city.

The prototype was made out of paper mache and the use of spare parts of a broken pair of headphones.

My goal with this prototype was to create a space by a visual and an acoustical way. The basic idea was to design a wearable space that would interact with the environment both visually and acoustically. The coloured glass lenses would use different colour depending on the mood of the user and the ear muffs would act as noise cancelling devices.

For the visual experience it was used coloured transparent paper and plastic and foam cups were used as ear muffs to alter the auditory experience.

Another idea that I explored was a series of headphones with different uses. One with water inside the ear muffs (bottom right), one with sliders on both sides for creating a private space (bottom left) and one with interchangeable components that would alter the surrounding sound in various ways based on user’s mood.

All of the prototypes were made by using cardboard, masking tape, spare parts of broken pair of headphones and blue foam.

Making of Cochlea

The model of Cochlea is constructed mainly by wood. First, 260 slices of 12mm MDF, taken from the 3d model, were cut using a laser cutter. Then they were glued together in order to create the outer form. The front part of the bench was created in the same way. Afterwards, the form was sanded and then painted. The final piece is intended to be made out of concrete. The purpose of the full scale model was to create a similar user experience as the concrete object. Also it is intended to be used as the master object for the creation of the one piece rubber mould.
