How the measurements were taken Basically, I draw this measured drawing by taking photos.

And in order to take an accurate scaled photo, I set the camera lens to be further than 28mm to avoid deformation.

And for the part I couldn’t trace directly from the photo, I use ruler to measure them, like the height of the inner surface and the width of the stainless steel handle.

However, when I was drawing the section, the curve hollowed depression is hard to measure and not able to be taken photo. Therefore, I borrow the idea of the vase in the reading 300 years of industrial design(Jensen), by inserting a piece of cardboard paper into the hollow and trace along the curve by using skinny pencil lead.

Analysis

The average distance between the eight steel wire is 6.5mm. Although the wire is not very hard, the thickness of its diameter help it cuts the egg sharply enough.

The aviliavle switch angle of the cutter is between 180 degree to 0 degree, which provides the biggest flexiablity and space to put different eggs in different sizes.

The depth of this depression is 14mm which is generally half of the diameter of general size eggs.

It designed efficiently to prevent the egg from slip away.

The egg cutter are in simple construction and consists 3 parts wich are a plastic hollowed holder, a stainless steel handle and 8 stings of wire cutter. The size of the egg cutter is 83.5mm x 113mm, which is easy to carry. The material are light and easy to be clean as well.

The distance between every plastic strip is 3mm to make sure the tinny smashed pieces fallen from egg would not stuck into the gap and easy to be cleaned.

The material is plastic and stainless steel, which are both light, easy to be cleaned and durable.

The section in the middle of the cutter is made up by the insertion of two pependicular eggs. And we get a series of seven sections which are arranged in a particular order.

The width of the section is increasing while the height of the hollow becomes deeper. section D is the center section, and the sides of it are symmetrical.

The seven sections lies as the diagram aboved shows.

The main idea to model this egg cutter is to input a plan drawing first, and scale it into 1:1 by drawing an actual scaled line. And then, use wireframe to tracing the outline of the surface and all the edges.(figure6) Therefore, I am able to extrude surface, panel and solid to connect and boolean.(figure7)

figure 6

The middle section was extruded as a solid rectangle, then I draw 8 solid rectangle to make Boolean from the big rectangle. And the negative space in the middle was boolean by creating two perpendicular solid egg. The slope at the top was achieve by boolean difference with inserting an angled slope panel.(figure7)

figure 9

The curve edge was achieved by the command of “fillet edge”. figure 7

The curve handle was simply made by command of “pipe”. (figure8)

figure 10

The joints were created by pipe a curve line and Boolean difference with the handle.(figure9) Then I have copy and rotated the handle to show the movement of it to present how the egg cutter works. Then stainless wire line have to be in the right position between the hollow gaps. (figure11) figure 8

Sketch Model

Reconfiguration by using the object itself

I cut off the seven sections in the egg holder, and dried to cre ate a volume by using the negative space in the section.

The photography consists of two models arrange in differ ent connection. The two images on the left shows the volume made by the height difference and thickness difference of the sec tion. The sections are connected at one side of their lone edg es.

The two images on the right shows the volume made by the negative curving space of the sections. The rotation of the set ting creates an egg shape volume.

I simply use blue track to stick the bottom and top point of these pieces together, and set them in two rotating pattern.

I also utilized and explored the flexibility of the plastic material itself to magnified the volume we trying to create. That was reached by fold the weak middle point of the piece.
