Measured Drawings
1.1 Object: Measured drawing set of selected object.
1.1 Process Description: Text and Images describing how object was physically measured + photo of object
As the teeth are extruding from the base I has difficulty measuring it using ruler as the scale does not start at the end of the ruler. Hence, I decided to mark the height on a strong strip of paper then measure it using ruler. I used the same strategy while measuring the gap between the teeth and the side of the base
Analysis
1.2 Object + System Analysis: Analytical sketches/drawings abstracting the rule/material logic in the object
45 degrees
This 45 degrees angle increases stability while plates are stacking on top o each other as it encourages more friction to form between each the top and the bottom of the plate, hence prevents sliding motion
This drawing displays the vertical stacking motion of the egg cutter when slicing eggs.
I decided use a string to allocate each piece to be on top of each other with uniform vertical spacing between each of three plate and the base. This helps be to draw up this elevation
Bottom
Top
The bars in side the hollow plates are thicker at the top that aid cutting
Digital Model
1.7 Digital modelling process: Description of how object was modelled using text/diagrams/screencaptures
Pattern on the base
The base of the egg cutter was made by tracing the plan of the top view then extruded it to for solids. Then extruded the polygons that formed by the 6 groups of teeth. Using the boolean command to create the cavity between the teeth and the base of the egg cutter. Similarly, the curvy hollows on the base of the object is punctured by extruding the curve and boolean the base. (Refer to Appendix)
Curve on the teeth
The curve on the teeth is formed by placing a three 3D drawn egg and place it one third down the teeth then boolean it.
Each of the cutting plates are formed by offsetting the curve traced on the plan of the base by 5mm smaller in radius. Then extrude it
Each small slicing bar on the plates are created by extrude curve tapered as the bar is thinner at the bottom for slicing. (Refer to Appendix)

This expresses the potential effect
This model is constructed using paper and glue. Each strip of paper is rolled to form a relatively rigid bar, combining to configure into triangles. Essentially, the model is a repetitive pattern of combining four triangle vertically, horizontally and diagonally in a consecutive manner. Ultimately, this pattern circles around to from a hoop. This design is a combination of the three sketch design

How does this respond to your personal space?
Elevation 2
An alternate effect of this design is to isolate the person who is sleeping from other people. As the cover not only blurs what the user can see, but also obligate people from seeing who they are.

Elevation
How does this respond to your personal space?
The cavity behind the frames moulds to the shape of the and and shoulder for support. This induce a sense of security.

Sketch Design #3 [Cuts__ cross] rope Transparen t inflatable polyether
Elevation How does this respond to your personal space?
Allow a sense of freedom while sleeping as the transparency still allow user to see their surrounding while sleeping.
