Exploring Filtering
A Short Project on the Filtering Process
In the week-long short project »Exploring Filtering«, Cluster member and interaction designer Thomas Ness, and textile designer Veronika Aumann dealt with the topic of Filtering with an open-ended mindset. The goal of this creative exploration of filtering processes was to gauge and express them in a practical and tangible way, respectively.
The point of departure for this was not a particular substance to be filtered or a specific substrate to be attained. Rather, the interest lay much more on the actual processes of filtering in and of themselves and the filter as an object. In the »Design Lab«, different kinds and methods of filtering processes were tested hands-on with familiar prototyping materials and techniques and transformed into six narratively and visually impressive representations.
The short project functions as a playful starting point for further discussion on the topic of filtering. The experimental installations illustrate different filtering processes, while also outlining each material activity.
A simple and open definition that served as a common foundation for the practical exploration was formulated in the project: Here, the crystallization of single aspects from a whole is meant by filtering. Thereby at least two distinguishable parts, states, or forms of a substance, separated from one another, are depicted.
One approach consisted of using substances that are often filtered, as filters (such as air or water), and to filter materials that are often used as filters (such as textiles or sponges). A further approach was to observe, as far as possible, the filtering processes as detached from certain outcomes, as well as to highlight a broad range of principles and effects. Through this, a unique attention to the filter and its transformation during the filtering process was developed.
Filters can be described by that which they filter, by that which they filter out, or else by the way in which they filter. All three methods of description provide access points to the topics addressed in this short project.
The six experiments (Color vacuum, Attraction, Color fan, Air bubbles, Liquification and Color filter) are attached to the Cluster’s three filtering methods (selecting, extracting, modifying) and emerge from mechanical or chemical processes.
Color fans
The orange-red liquid separates into different colors on a cotton material.
Duration: approx. 17 seconds
Structure: Cotton material, water, salt, lemon, soda solution, color indicator
Air bubbles
A stream of air from a mechanical fan maneuvers the equally-sized balls of different materials with varying force and lets them fall, sorted in space.
Duration: approx. 3-4 seconds per ball
Structure: Acrylic glas tube, directed fan, balls (paper, wood, metal), container
Color vaccum
The yellow portion of a red liquid is sucked out.
Duration: approx. 4 hours
Structure: Pigment, water/Oil dispersion, felt strips, container
Attraction
The smaller balls get pulled up through a foam material. The larger balls remain on the bottom.
Duration: approx. 3 minutes
Structure: Small & large metal balls, foam material, magnets, servo motors, container
Liquification
The thick gel liquifies upon contact with the foam material and consequently seeps through it.
Duration: approx. 3 minutes
Structure: Water, super absorber, salt, foam material, color indicator, container
Color filter
The double-layered cotton material changes the water seeping through it as well as itself. It removes the color from the blue-green water and itself changes color from black to orange.
Duration: approx 1 minute
Structure: Water, cotton material, chlorine, color indicator
What was noticeable during the entire design process was how fluid the transitions were into the filtering process of the three described approaches (what is filtered, what is filtered out, and how it is filtered) and how strongly this intersecting affected the creative experimentation.
