LEFT VIEW
The stool was physically measured by using scale rule and protractor. The top and two sides of the stool are traced on paper to draw the basic outline following the drawing of the croissants from Miralles & Pinos(1994). These measurements later are used to model the stool in Rhino by using InterpCrv, PlanarCrv, ExtrudeCrv command. Some parts such as side panels are mirrored by using Mirror command to boost the process. The plastic joints are modeled separately before being placed in the panels.
1.2 SYSTEM ANALYSIS
The convex surface on one panel fits perfectly with the concave surface on the other panel
The most interesting mechanism of the stool is its folding transformation , which is based on the simultaneous horizontal and vertical movements of all 8 panels.
Semi-circular plastic joint create a flexible pin joints that allow rotational movement between panels
When a vertical force (Fv) or horizontal force (Fh) is applied onto the stool, panels 1 move horizontally in opposite directions, followed by the rotational movements of other panels.
The stool gradually transforms into its open condition with the side panels forming a strong scaffold that supports the surface above.

INSPIRATION: My sketch model is primarily inspired by the image of butterfly’s wings. These wings are flat and twodimensional but under different sources of light, it can create beautiful three-dimensional effects and the effects would change in different viewports and environment. With its flexibility in shape, the sketch model has the potential to be developed into various dynamic structure by combining them together in many different orientations.
1.4 SKETCH DESIGN
DESIGN 1 This design aims at creating protection around the right arm and chest area which is usually vulnerable to external attack
DESIGN 2 Butterfly shapes in different scale combined together create an extended structure that provide protective shield around sensitive neck area and back, allowing user to lean on and have comfortable sleep.
DESIGN 3 Spiky chain of butterfly shapes wrapping around user’s head and upper shoulder to prevent attack and minimize interference from surrounding environment to the eyes, enabling a quality sleep
13
Reflection from Module 1 The sketch model has great potential to develop into more dynamic and complex shapes. However, the three sketch designs appear to look similar to each other and do not have much distinctive features that create complexity and sophistication. Also, folding mechanism needs to be analyzed and utilized more efficiently in the butterfly shapes as well as how they would be joined together. Different materials will further be tested to find the most suitable material for the structure as paper tends to dangle under self-weight, which is aesthetically unacceptable and hinders further development.

2.1 Desgin Development Intro Considering feedback from Module 1, we decided to further develop the butterfly shapes from Trinh and the leaf shape from Nik. Our initial design is a double-layer structure, in which the interior layer provides comfort for users while the exterior layer acts as a protection, preventing interference from surrounding environment.
Module 1 Sketch Model
With its sharp and angled geometry, the butterfly shapes are suitable to form the exterior layer. Besides, the profiling surface of the leaf shapes provides perfect comfort for user. We also worked on new sketch model to refine the current sketch model from M1. Protective exterior layer

GAIA focuses on the concept of isolation and transformability by creating collapsible and portable device.
Translucent polycarbonate sheets can absorb and diffuse light, and they are connected by zip ties.
APPLIED TO DESIGN
The collapsible mechanism can be applied to our sleeping pod to enhance its portability and flexibility
APPLIED TO DESIGN
Polycarbonate sheets are potentially suitable for the panels in our design. Also, zip ties can also be solution for joining the panels together

From precedent research, we examined the collapsible function of GAIA’s backpack to enhance the portability of current sleeping pod design. We also decided to use polypropylene as main material for the panels due to its translucency and flexibility. The timber frame has been profiled to fit perfectly to user’s neck and back area , providing comfort and protection from behind.

2.6 Design Proposal V.4 JOINTS
We tested out different joints including connecting the panels by using thread but it was too thin to resist the force.
We also tried zip ties but the ties were too big, making the system looks unaesthetic.
We finally came up with the pin joints between panels by creating holes on one panel and arrow shape on another panels. This allows panels to join together without any additional joints
PANELS
Different shapes were tested to improve the current panels
Curved system required many joints, which reduce the flexibility of the structure
This structure has too much space and gap in between, which weeken the idea of privacy

REFLECTION FROM MODULE 2 Module 2 marks the innovative combination between two different material systems, which are Panel & Fold and Section & Profile. Taking ideas from precedent research , we created a foldable and portable system made out of polypropylene panels with arrow-hole joints that allow panels to be connected to each other without any additional joints. This system is sufficiently supported by 3mm MDF frame that is based on Section & Profile system to provide rigid protection and comfort. Also, the design process is greatly aided by the use of Rhino through Paneling tools, ExtrudedCrv, PlanarCrv, etc commands. Rhino plays a key role in providing a 3-dimensional representation of our ideas and efficient platform to test new design.
MOVING FORWARD MODULE 3 Prototype V,1 has series of problems that need to be further improved in next modules: - The prototype appears to be two systems joining together rather than one performing system. - Elastic characteristic of polypropylene make the panels dangle under self-weight and gravity force, which distorts the overall structure. - Considerable amount of force is required to compress and keep all panels in their folded position - It is difficult to compress and keep all panels in their folded position with current fastening details

3.0 FABRICATION
Trinh Pham Henrik Green Nik Lee 33
3.1 Fabrication Introduction Taking feedback from Module 2, there are several key concepts that need to be tested and developed: The panels appear to be flat that does not create much space and volume, thus resulting in two-dimensional appearance of the structure. Our solution is to further develop the panels into a three-dimensional shape but keeping the overall outline as we are happy with the arrangement of all panels.
Site is taken into consideration. We chose the long bench in the atrium in Melbourne School of Design as location for our sleeping pod.
34
The initial folding function seems to hinder further design development, so elimination will be considered. With the consideration of eliminating folding function, MDF frame will be redesigned to better support the panels and to solve the problem of having two seperate system joining together.
Frequent movements and activities including walking, eating, running are observed throughout the day. Therefore, our aim is to create a portable and flexible sleeping pod that does not take up much space or hinder movements
3.2 Design Development & Fabrication of prototype V.2
Double layers add volume and space to the structure
Outline of personal space
Top view showing internal round layer and sharp external layer
Series of shapes were tested and new panel with greater volume was created by folding different parts of panels in opposite direction
In order to increase volume, we considered having two layers: a round internal layers to create comfort and a sharp external layer to clearly define personal space and set barriers between user and surrounding environment
Folding the panels in two different directions increases internal volume
The connection points of two panels create a sharp structure that clearly define personal space

Having eliminated the folding function, a new frame was designed to provide lateral support to the panels. Unlike the rigid geometry of the panels, the frame was designed in free form to enhance its flexibility and interesting look.

Prototype V.2 solved the problem of having two separate systems joined together by placing polypropylene panels in three rolls around the new MDF frame. With its translucency, the panels soften and blur out the frame as if it has been disappeared into background. The panels also perform as semi-invisible barrier as expected. The outer profiling edge of the frame well fits with the bench. However, the lower part of inner edge curving inward creates discomfort to the back of user.

REFLECTION FROM MODULE 3 Module 3 has proposed one of the most interesting aspect of Design and Fabrication process, which is how digital and physical model and the fabrication techniques can have great impact on the design and sometimes change the initial ideas. From week 6 readings, Kolarevic (2003, p.35-39) introduces different fabrication techniques including two-dimensional fabrication , subtractive fabrication and formative fabrication. This has broaden our understanding of great availability of techniques and how our ideas would not be limited by the lack of technology.
One challenge was that bamboo plywood after laser cut would sometimes have its thickness altered by 0.5mm. This small change in fact had a huge impact on our frame model. The 5mm notches are no longer fit with each other, thus weakening the whole structure. We had to used balsa to solve the problem and extra care was taken.
To successful produce the final product, we have been greatly aided by the help of fabrication techniques, physical model, and 3D modelling tools such as Rhino.
In addition, reading from Iwamoto (2009) on folding aspect has also helped us better understand the folding techniques and how to develop complicated structure from simple and geometric shapes. We applied these ideas into creating 3D panels by folding them in opposite directions.

4.0 REFLECTION

4.0 Reflection Throughout three months of designing and fabricating a complete sleeping pod, there have been numbers of interesting concepts raised in each module and challenges that I and my team had to face in order to move forward. Module 1 guided me through the process of closely analyzing an object and designing a refined sketch model based on the physical characteristics and mechanism of the object. I was greatly amazed by the number of rules and principles I could draw from a simple stool to develop my own models. One of the very first challenges that I faced in this module was to come up with a refined design from the object. My ideas were locked into an invisible frame as I did not have a holistic approach from different angles and scale to fully explore the potential of my sketch model. Consequently, all my sketch designs bear many similarities to each other and did not really response to the concept of personal space. Moving to Module 2, with the sharing of different ideas and designs from teammates, we came up with more sophisticated design that well responses to the main themes in the module. Rhino 3D modelling became an incredibly helpful tool to visually represent our idea and explore other potentials of the design. However, sometimes the lack of software skills might hinder the design process and did not allow us to fully represent our ideas. I also found this module the most challenging of all three because we had been moving back and forth with our design ideas many times and were completely stuck at some points. From this I have learnt an important lesson that a design is only successful when it has been tested in reality. Also, critical feedback and peer review play an important role in developing and refining our model. The fabrication process in Module 3 helped me explore how physical/digital model and fabrication techniques can have significant influence on design process. Laser cut enables me to explore wider range of materials such as MDF, bamboo and polypropylene and understand their behaviors. However, at times conflicts also occurred that can dramatically change our design. We initially wanted to have a foldable sleeping pod based on folding mechanism. However, after laser cut the polypropylene panels and joined them together, we realized that due to the characteristics of the material, it is difficult to compress and keep all panels in right position without considerable amount of force. Testing our ideas on physical model has helped us quickly understand the problem and come up with better solution. Overall, we successfully produced a complete sleeping pod with through different critical process including 3D modelling, subtractive fabrication, prototype and peer-reviewed feedback. Considering the concepts of democratization of energy and technology raised in the reading of Rifkin and Macmillan (2011) and this sleeping pod design, it is noted that we are living in the era where everyone is given enough tools and technology to make their own product and become manufacturers. With the help of 3D modelling, printing and advanced fabrication techniques, we can better visualize the world and go beyond the boundaries that old worlds have set.
