Pandora Box-Cantilever

Foundation 3D: Pandora Box-Cantilever

The word I got from the Pandora’s Box was Cantilever. I have searched on Wikipedia about this word: A cantilever is a rigid structural element, such as a beam or a plate, anchored at only one end to a (usually vertical) support from which it is protruding. Cantilevers are widely used in construction, such as in bridges and buildings. After a preliminary understanding of what is cantilever, I composed 2 sketch models on week 2.

  • D: Dominant
  • SD: Sub-dominant
  • SO: Sub-ordinate

3 views of Model 1:

Front view-the sizes of SD&SO are quite similar.

Side view-the widths of D, SD&SO are similar……

Top view-SD cannot be seen; the size of SO is too big.

3 views of Model 2:

Front view-the sizes of SD&SO are similar; the length of SD is longer than 1/2 length of D; the left side of the model is too flat.

Side view-the sizes of SD&SO are similar; the width of SD is longer than 1/2 width of D; everything is centralized.

Top view-SO cannot be seen; D&SD are shifted.

The feedback I got on week 2:

  • Keep rotating 3D sketch model while assembling it, make sure D, SD & SO can be seen from all angles;
  • Avoid similar sizes of SD&SO, and SD&SO won’t be shifted from different views;
  • No flushing, avoid flat looking of the 3D sketch model

With these points in mind, I tried to improve the two models above and explore some more different composition of Cantilever on week 3.

2D Analysis of Model 4:

The feedback I got on week 4:

  • Avoid putting everything along the central axis, try to make the model more interesting
  • Think about the materials that I am going to use

I decided to choose Model 4 as my final model.

Final sketch model：


Final adjustment:

  • The thickness of SD&SO are quite similar, SO should be cut in half. And after that, I decided to place the SO along the principal axis of SD.
  • Shift SO&SD to the left 1/3 point of the length of D.

Materials

  • Dominant: Chipboard
  • Sub-dominant: PVC sheet
  • Sub-ordinate: Rectangular ring

Considering the future application of this model, I decided to use chipboard(D), glass(SD), and metal wire(SO) as my materials at first. However, during the final model making process, I wanted the SD to be double layers, so I used transparent PVC sheet to replace the glass as it was in lighter weight and easier to cut.

My idea was inspired by Mash Bar. Mash is one of the smallest bars in Amsterdam, the designer used chipboard all around for the interior to create a cozy and warm atmosphere.

The main materials I can see from the bar’s interior are chipboard, metal, glass, and fabric.

FINAL MODEL

Application

1. Note board with a LED glass clock

The control buttons are placed at the edge of the note board. As the glass board is double layered, the user can put a paper in between and then write notes on the glass board.

2. Table

When you are not using the table, you can lift it up for more space. And now, it becomes a glass note board again…

2D Analysis

2D Analysis of a key chain with a little monkey.

The interesting 3D object I brought for the first 3D lesson was a keychain with a little monkey. From the picture, we can see that the proportion of the length of the chain is about 1:1 to the height of the monkey. The little red monkey is really eye-catching, as it creates a weight down there. For the chain part, it creates a negative balance.

Now, let’s take a close look of the monkey. Here are 3 views of the little monkey.

Front view

Picture shown is the front view of the monkey. We can see that he is in symmetry completely. (except the black spot on its left foot…)

For the colour of the monkey, vibrant red as the main colour which attracts our eyes first is the dominant, and the light yellow of its skin acts as the subdominant. Black is the subordinate, although it is quite less which is only applied for eyes and nose, it can be seen clearly as well from the light colour face. I think it is also a pairing of contrasting colours.

A character with bigger head, shorter and smaller arms and legs is definitely very cute and interesting. Comparing sizes of the head of the monkey with its ears, arms and legs, it shows the pairing of contrasting volumes. And the head of the monkey is almost half the size of its whole body, which makes the proportion of the head to the lower body part is about 1:1.

Side view

Different from other views, the side view of the monkey is asymmetrical. The interesting point of the side view is that its ear, arm and leg are all placed along the principle axis.

Top view

Same as the front view, everything is symmetrical. Ears and nose of the monkey are on the principle axes and, it is obvious to see that the nose and ears create an isosceles triangle over there.

 

Another interesting point is that all the three different colours of the monkey can be seen at the same time from the views above.
