# PARAMETRIC STRUCTURES

### WHAT IS PARAMETRIC DESIGN?

Parametric design is a process based on algorithmic thinking that enables the expression of parameters and rules that, together, define, encode and clarify the relationship between design intent and design response.

### EXISTING STRUCTURES STUDY-

### 1.APPROXIMATE CHAIR EZCT

pdf of detailed study

### 2. CELLULAR AUTOMATON

each of a set of units in a mathematical model which have simple rules governing their replication and destruction, used to model complex systems composed of simple units such as living things or parallel processors.

64 elementary bidimensional binary cellular automata with 1 white starting central point

### 3.VOXEL CHAIR

Robot-made chair designed by Bartlett researchers

the original chair is solid plastic, DCL’s is a complex web of hollows created by a robot extruding plastic in one continuous 2.36-kilometre line.

### 4.KERFING & DOUBLE KERFING

Kerfing (or lining) provides a gluing surface for the joining of the backs, tops, and sides. Some builders use it with the kerf facing out, so the kerfs are visible, and others glue the kerfed face to the inside hiding the kerfs.

KERFING

DOUBLE KERFING

the increase in stiffness and load capacity as the surface is bent in one and two directions.

### 8. READ MORPHO ECOLOGY – BY MICHAEL HENSEL

‘Morpho‐Ecology’ is a concept and design approach that combines the notion of ‘morphology’, and thus intrinsically ‘morphogenesis’, with the notion of ‘ecology’. In the early 19th century, in the context of his studies in botany, the poet and writer Goethe defined morphology as the study of forms; he combined the study of ‘Gestalt’, or structured form, with the process of ‘Bildung’, or formation, which acts continuously upon form.1 Later on in the century, the term ‘ecology’ was coined by the German physician and zoologist Ernst Haeckel, who defined it as the science of relationships between organisms and their environment.

### PROCESS

choose one

1.Create small components and play with them- like tessellate them in space 2d of 3d

2.Explore the properties of different materials and try to change them through Enovation.

### AIM-

1. Motion in parametric structure

2.Tessellation of one unit

### IDEATION-

EXPLORATIONS OF UNITS WITH USE OF EARBUDS

EXPLORATIONS FOR INTERLOCKING

EXPLORATIONS OF JOINERY BETWEEN TWO UNITS TO MAKE IT TESSELLATE IN XY PLANE AND XYZ PLANE-

### Final unit 1-

### final unit 2-

in this exploration units are tessellating in same way but here coefficient of z is not 1, in this structure interlocking is such that every second square is moving in z direction also. here

coefficient of x= coefficient of y

and coefficient of z =aR

where a is number of square from center square and R is radius of the cylinder (here of earbud)

2.observation-

when its hanging from center square its shape is like dome because of change in z value.

due to locking system structure, you can totally collapse the structure and by pulling edges of outermost squares, you can regain the initial structure.

the structure can be changed by changing positions of outermost square units vertices, it works like a concertina.

### Applications-

1.Hammok

3.Ceiling light fixtures [convertable]

4.convertible shelters
