Introduction
Basically, our sleeping pod focuses more on comfort and the concept of personal space by covering the important parts of the body while sleeping. Hand sewn cushions are folded by the triangular panels made of foamcore board. The scoring method gave us the ultimate effect of folding. However, the feedback that we got was the panels do not really relate to the human body and it was very random. Also, the cushions were very flimsy and could not stand. So in M3, we decided to revamp the panels so it can fold more towards the human body shape and make the cushions sturdier so it can stand by its own.

Design development
Looking back at the feedback we got from M2, we found out few issues while trying to achieve our outcomes. Our prototype was successful but somehow we did not fulfill the concept of paneling. Thus, we had to go back to the starting point to find out the root of our problem which is rethink the concept of folding and paneling. That is why we have changed the random trangulation panels into a more systematic one that relates to the human body more.

Design development + fabrication of Prototype V.2
To redesign the triangle panel on the pillow, we experimented it on a smaller scale cushion. Instead of just randomly pasting the triangle panels on the cushions, we decided to shape them according to human bodies.

INCLUDE IMAGES FROM THE TEXT
Briefly outline the various digital fabrication processes. Explain how you use digital fabrication in your design? There’s reverse engineering, which digitally represents the geometry of a physical model. “Point cloud” is a pattern of points that is created by te physical model through scanning, and a close approximation of the model’s geometry is interpreted by the conversion software. Besides that, from physical to digital, the most commonly used technique is CNC cutting (2D fabrication). With cutting technologies such as plasma-arc, laser-beam and water-jet. Under CNC cutting, there is subtractive fabrication and additive fabrication. As obvious as it is listed in the name of fabrication, subtractive fabrication is the removal of a specified volume of material from solids using various milling processes, and additive fabrication is by adding material layer by layer, which is the opposite of milling. Meanwhile, in formative fabrication, heat or steam is applied to the material to deform it until it reaches its desired shape. For us, we found the Aegis Hyposurface particularly interesting because og the highly faceted metallic surface that is deformable and flexible. That is what we are trying to achieve in out design, however, we did not really use digital fabrication because it did not give us the outcome that we wanted. By scoring our board, we managed to create a folding pattern that applies to the shape of the body and cushions inside to accomodate for comfort. The triangular panels are scored accordingly to accomodate the shape of the body and also thinking about the concept of personal space.

Reading applied to design How does the fabrication process and strategy effect your second skin project?
Although we did not use any specific fabrication, we got our inspiration from the technique of reverse engineering, with the geometry of our physical model represented in Rhino 3D. We first started with building our physical model through non-stop experimenting and then transferred it into Rhino 3D to digitalize it. Besides that, we used additive fabrication by sticking the white triangular panels onto hand sewn cushions to keep with the concept of panel and folding. The purpose of the triangular panels and its specific geometry is to make the cushions fold according to the body’s shape. The addition of the panels not only make the whole structure more aesthetically beautiful but also has a functional purpose. We made it deformable and flexible so it can be folded in any way. However, one flaw in our design is that some panels only can be folded in a certain way at a specific angle.

Describe one aspect of the recent shift in the use of digital technology from design to fabrication?
In the recent shift, digital fabrication became the main technique to produce a virtual and physical model. Different from traditional methods, digital practices is able to generate a representational drawing to final production without limitations. Three-dimensionalcomputer modeling and digital fabrication can expand our design thinking and break the restrictions of architectural form and construction. Thus, a seamless connection between design and making in design aesthetic is achievable by computerized process.

Folding Pattern of Our Design

Reading applied to design Referencing from the lectures and readings, what is the implication of digital fabrication on your design ?
The main implication from digital fabrication that affected our design is the technique of folding. Folds are able to turn planar surface into three-dimensional volume as they are materially economical, visually appealing and effect at numerous scales. A material became more flexible yet stiff at the same time. The planar surface can also be self-supporting when the volume is created.

Prototype Optimisation - Effects
Since the sleeping pod needs a user to be the spinal support, when he or she sleeps inside, the whole structure kind of falls on the user, giving them a very enclosed private area for a good rest. And especially when its black, the user can fall asleep with ease ask the environment is dark. Personal space is considered very private and excludes one from the outside world.
The internal effect from a user’s view. Black cushions are able to facilitate with personal space to users by shading them from light and provide a dark environment to sleep better

Prototype Optimisation - Fabrication
These are the triangular panels that are attached to the cushions, mostly focused on covering the head and upper chest, which is the important parts of the body and needs more protection.

To properly fit according to the human shape, the triangle planar surface is modeled on Rhino then folded according to the human shape. In this case, our folded triangle is volumised to the standardized dimension of a human’s head.

Prototype Optimisation - Material Usage
Duct tape is stuck to the line where the board was scored to strengthen the folding and bending motion.
Garbage bags are chosen to be the infill of the cushions for few reasons. Firstly, they are costeffective and light but also soft at the same time. Secondly, plastic bags are non biodegradable. Thus, reusing these garbage bags can reduce wastage to the environment.

Fabrication Sequence
Step 1: Sew DIY cushions by stitching two black cloths and flip it inside out to create a neater look.
16
Step 2: Stuff the cushion with garbage bags and stitch the opening together with tiny whip stitches.
Step 3: Twirl metal wires together to form a wire mesh. To make it stiffer, metal wire is wrapped around a intersection to fix it in place.
Step 4: Stick the wiremesh to the cushions for flexible support. Extra duct tape is adhered for extra securance.
Step 5: Triangle panels are cut according to certain patterns and foldings are secured using duct tapes.
Step 6: Triangle panels are later attached to the pillow to shape the structure according to the human body.
