Haptic switches / Valves- electrical schema




My intent is to build a mock up of the wall, with flex sensors embedded into the skin membrane. The investigation hopes to explore the haptic relationship or the possibility of a tactile interface that encloses our dwelling. The muscles would be connected within the membrane , in tension due to the interior compressive pressure forces on the pod. The mutations of the 'wall, roof, floor' perhaps starts to explore this relationship. The intent would be to have solenoid switches attached to the air line to the muscle bladders, and through a relay system, create a condition of air release when power off, air contained when power on.

Wall section



The current drawing is an investigation in to how the skin wall integrates heat, plumbing, pressure, and structure into its material. Some issues are the end connections of the pneumatic muscles matrices ( in specified locations to come); retaining wall details for excavated wall, retaining pressure in pods through pressure lock detailing. I figure the drawing has a lot of work to be done but gives some intent. The retaining wall will act as my foundation and the skin, muscles structure will build from that. Tie rod to skin connection will also need to be worked out. More drawings to follow.

Studio drawings- Context/ extent of device




The following drawings are just a glimpse of some of the scale that i will be working at. The intent is to have underground pods within a womb like membrane. These pod dwelling incorporate the structure with the pneumatic muscle. The goal is to have flex sensors within the wall skin that foster a tactile relationship between the inhabitant and the skin. The skins connection to the muscles, and its integration within the wall assembly of pneumatic muscles is my next step.

Pneumatic muscle connection




Here is a sketch and a prototype of a possible connection piece for the muscles. I am starting to investigate how a matrix of these muscles can be connected, with the wall membrane assembly.

Solenoid valves





Working with Patrick on some electronically activated valves for the pressure system intend to create. Here are some preliminary ideas: either the solenoid is within the pressurized system or the solenoid pinches a latex bridge between hoses of the system. The investigation looks at how to transfer the mechanical movement of the solenoid into a pinch action onto the tube? Here is a prototype:

Pneumatic muscle






I am currently building my own pneumatic muscles, exploring the braided sleeve pattern, and the implication of the weave in the contraction of the bladder. Is there a potential in a secondary skin to dictate a certain type of contraction. And more importantly what role do the valves play in that system.

Pneumatic / Hydraulic principles






I have been studying old pneumatic sewers from Europe in the 19th century. The one piece that was interesting was the sewage ejector. The ejector consists of a sealed chamber that fills with sewage from a one way valve and a float sensor activates a pressure valve when the tank fills to a certain point. A sparate compression chamber pressurizes the tank and cuase the sewage to be ejected through an outlet pipe, at a higher elevation then its entry into the tank. My interest lies in the compatementilization of the sytem and the use of valves to move a fluid from one place to another: in concept the basis for hydraulics and pneumatics.

Valves



I cam across this blog regarding a homemade solenoid valve. I am currently working on my own valves, trying to sort out the mechanics of switching within a pressurized environment( prototype photos to follow). The issue is creating a movable plunger or rotating switch that retains a seal yet has minimal friction against its axial enclosure.

Expansion of boundary

Some of my exploration of domain has been with latex bladders, as a poetic investigation into exploration of the unknown. The grotesque becomes another element of investigating the resulting outside and interior environment of a possible skin enclosure. Do pneumatic muscles provide an opportunity for supporting an experience or retain the posture of an inhabitants program?

Terra Incognita





My current work is looking at how a colony environment is networked within the shared livelihood of a butcher house. The transition between the known and unknown world allows the potential for a hermetic environment, a escape into fantasy. This exploration of the unknown known and the unknown unknown is manifested and informed via a skin. The inhabitation is a dynamic pressurized environment, responsive through a skin . Does a muscle, pneumatic or hydraulic motivated, allow for a play with this cognitive/ real dualism within that environment.

Program strategy from last semester


Is there a potential for a thick, integrated skin that adapts and interact with our bodies? The potential might allow for a contemporary interface between our subconscious, our body and our enclosure. Can architecture become more intimate for people whom view/inhabit it, and for the city in which it is located: something that is missing in the generic buildings of today. Everyday living allows an investigation into a dualism between my needs for simplicity and complexity, the infinite and the finite, the known and the unknown: are these mirrored by the ebb and flow of my anxiety and comfort? Is the bond between the user and his/or her everyday realm exhibited through personal fears and pleasures: through thresholds of our daily ritual? My interest lies within the discrepancy between our cognitive world and the real world: suggesting a stronger boundary that extends beyond or recedes within our physical boundaries.

The work of Frederick Kiesler’s discusses this potential for a contemporary relationship to our domain. Kiesler correalism investigates the body’s role in architecture: the dynamics of continual interaction between a person and his/her daily realm. Keisler’s believes that continuity, in relation to the human body, is vital to creating space that interacts more deeply with ourselves. Freud’s discourse on the uncanny is linked to this idea of discrepancy: a difference between our repressed experiences and our present ones. Freud’s work contributes to an understanding of the relationship between our fears and anxieties of the real world. Inflatable artist Hans Hemmert’s exploration of everyday living situations comment on the continuity of surface, where the traces of objects become more intuitive and the familiarity begins to vanish (Appendix A1). Interior surfaces have no visual pauses. These spaces he creates are hermetic. The unification of the contours of the environment suspends space, reducing our gravitational cues. Like sensory deprivation chambers, the boundary between the real and the unreal become ambiguous. The space formed imposes feelings of insecurity: producing an image of void or nothingness. “The familiar de-familiarized, the Freudian “Un-heimlich” in which the Sinister that which we were once entrusted with knowing and is later stamped out in a subconscious act of elimination.” (Anna Cestelli Guidi) The long-term objective of this research is to develop an understanding of designing architecture that responds better to the particulars of its context, operation, and its occupants: developing the relationship between our psyche and the individual elements that make up architecture as a whole.





SITE:

During a weeklong emersion of MontrĂ©al’s urban life, I discovered an ‘abandoned’ street that induced feelings of isolation. I felt as if indeterminate groups of people were gazing upon me, dead and alive. A fear of this unknown started to activate my curiosity for what lies behind these situational thresholds. My site is situated within the Mile-End industrial area, a neighborhood in existence since the 1870’s (Appendix A2, A3, A4, A5, A6, A7). The Mile-End area of the city is characteristically a multicultural artistic neighborhood, with large warehouses and factories that had been built adjacent to the Canadian Pacific Railway tracks at the turn of the century. During the 1950’s/ 1960’s the downtown located Garment district, was relocated just south of the center of the industrial area. Change had been contributed to the movement of immigrant garment workers to new residential suburbs along Mile-End. Navigation to the site is limited, by foot and/or vehicular, due to the isolation of the street within the Montreal street grid. My area of study incorporates the partially abandoned 1960’s concrete structures along Gaspe Street between St Viateur Street and Macguire Street. For decades, GaspĂ© Street was a hub of textile manufacturing. However, in the past years the number of companies involved in the garment trade has declined. Officially the garment district has since relocated a couple miles northwest to Chabanel Street. Currently the area is becoming inundated with artists, musicians, artist related businesses, with a mixture of residential and commercial use. The buildings within the site vary from 9 to 12 storeys of concrete columns and beam/slab construction, with loading and pedestrian access from Gaspe Street. My interest lies within the factories and the abandoned spaces between and below these solid structures (Appendix A8).



CONTEXT:

During the 60’s in the mile end district of Montreal, the old garment District encouraged the use of child labor in a sweatshop environment. My narrative continues 30 years later, when previous child workers have been brought back to the spaces of their demise. Through a failed attempt to collect monetary awards to victims of the child exposure to asbestos use in textile production, the now adult plaintiffs have decided, due to financial circumstances, to recover their losses through acquisition of factory property of the textile owner. Current asbestos levels are high within certain above grade levels, but they insist on claiming their rightful property underground. The narrative becomes a journey through a group of people’s lives as they navigate and inhabit unknown space, connected to repressed memories that form a network to their haunting past.


The textile-building site explores the potential for an outside source of influence onto people’s domain. Infrastructure speculation becomes a catalyst for integration and responsiveness within a bigger system (Appendix A9). The exploration of individuals as they deal with issues of threshold and boundary, creates a network within themselves and within another system of the city. Does a driving force of the city affect the behavior of the people in how they relate to their own domains. Is this force related to a city’s obsession for cleanliness, perhaps expressed through a sanitary infrastructure?
The compartmentalization of people’s lives, their space, affects how a ‘pressure’ may become a malleable and responsive element within that context.




PROGRAM STRATEGY:

I want to look at how our boundaries may lie beyond the physical ones we have built. Early exploration looked at the affect of everyday objects towards our behavior with a “skin”. The skin is a metaphor for the implied boundary created by the placement of objects and furniture due to our cognitive world (Appendix A10). I see the cognitive world as a dualism between what we perceive and what we don’t perceive. Sensory deprivation illustrated a contrast between one perception and another perception. I have actively searched for spaces that are more proximate to the body; there is a level of comfort with a space that is more finite in my perception. The creations of cells that inflate and deflate explore this perception difference: how does that affect the space in the street? There is also something valuable about the space between my boundary and my body, and the potential between that.

These skin moments, casts of repressed and present events, start to populate a study model. Characters navigate the other world of the sweatshop factory, confronted by thresholds and boundaries that are implicated by the site. The characters imagination and their behavior within and towards objects in a space affect the boundary they enclose themselves in. The world that starts to form becomes a direction or catalogue of relationships to a ‘skin’ (Appendix A11).

The intent is to explore the spatial and boundary implications of my experiences (through the characters) of fear and anxiety related to perceptional changes. How does a relationship to the ‘skin’ implicate a cognitive and real world?
