METHOD OF MEASURING Folding stool is a regular shape object, which can be measured directly by ruler according to its prolife.

R=35

Putting the ruler vertically can measure the height of stool. After get the dimensions of the top and bottom rectangles, four ridges from two sides can be drawn just by easily connecting the points of each rectangle.

Analysis

The hinge structure enables the folding function of stool.

There are two types of elements combining to the hinge, one has a notch on the two sides and another gets two raised parts.

Where they are connected is on the rotational axis which allows the panels to rotate in opposite direction.

HINGE DETAIL

The folding logic of this stool can be simplified to two separated plane with one intersection line as the second picture shown and this line is exact the rotating axis.

When the two sides fold in, they move horizontally and the top panels rise up vertically.

When the stool is folding to flat, the two panels from side fold in while the top ridge pops up.

This folding structure can be total simplified to a panel or paper folding form which may utilize the later research.

MODELING LOGIC

When creating these digital models, commands like mirror, fillet and trim are frequently used in rhino refer to its symmetrical shape with series of hollows and notches. I made this model by following its actual folding mechanic and composite. Each part of this model is grouped as a component which can be rotated along its axis. An explosion model is shown by deconstructing each folding panel from the model.

Sketch Model SKETCH MODEL 1

Using flat piece of paper to create 3d object and volume.

The volume and height can change according to the folding situation.

SKETCH MODEL 2

Combing triangular shapes to form a changeable and expandable paper complex.

SKETCH MODEL 3

Simplify the folding stool to paper folding system to further research its folding logic. Normally, the reducing from horizontal distance will cause the adding of structure’s height so by multiplying the numbers this shape in the same direction, it will still follow this rule.

Then by combing two sets of them, the central volume is created.

Sketch Design #1 Kinetic Expandable Centralized Foldable

An umbrella-like shoulder cover can expand according to body’s ac-tion. When panels expand, the volume is created to enlarge the per-sonal boundary, inversely, when planes are folding up, the personal space shrink.

Sketch Design #2 Module Translucent Foldable Regular

By following the folding logic of stepping stool, a single piece of paper module was created. Then copy the module by multiple times to create a complex which produces the inner volume for human body. Usually, people need more space in their front area so the system only stretch in in the front-back direction.

Sketch Design #3 Kinetic Extendable Triangular Responsive Enhance

When the body is relaxed, those triangular shapes are folding together thus sprawling around the body.

But if user stretch out their arms, the folding panels suffering the tension to extend so the personal boundary is expanded as well, which can enhance the effect of body’s action.
