Measured Drawings

In order to measure my object, a slinky, I utilised a variety of measuring techniques.

Due to the simple geometry of the object, a tape measure allowed for the dimensions to be anal-ysed.

While a slinky is at rest, it is a hollow cylinder, however a tape measure would be insufficient in creating a measured drawing of its dynamic state. Therefore, techniques using imagery were required to allow for tracing. Scans and photo-graphs were used to capture the elasticity of the slinky from different perspectives.

Analysis

In its initial state, a slinky is in compression. It is acted upon by gravity which pulls the ob-ject into the hollow, cylindrical shape.

When a horizontal force is applied to the top of the slinky, the cylindrical shape deforms due to the flexibility of the structure. If the force is strong enough to make the object ‘top heavy’, gravity will pull overhanging coils towards the ground.

As the initial coils of the slinky topple and fall to the ground, a ripple effect occurs, as the remaining coils follow suit. During this falling motion the elasticity of the slinky is witnessed as it stretches and forms an arch. The exten-sion from one loop to the other varies as the dynamic nature of the object creates con-stant change and adaption.

The slinky analysed for this module is made by coil-ing a long, rather thin piece of plastic. The circu-lar shape has an even distribution of mass, which when disrupted creates the typical falling pattern already described. The material used is not flat; rather, it is slightly concaved in the centre repeat-edly to allow for the slinky to stack neatly in its rest position.

Digital Model

The following digital models are made through Rhino. In order to produce these models, the slinky needed to be broken down into its baisc geometries. A helix and a distorted ellipse (for the cross section) formed the slinky.

Step 2: Create the cross sec-tional area of the slinky

Step 3: Utilise the ‘Sweep 1 Rail’ command to repeat the cross section in step 2 along the helix

Step 1: Create a helix wire-frame to create the base of the slinky

Sketch Model

PLAN VIEW

ELEVATION VIEW

This sketch model abstracted the object: the slinky. By simplifying the object by thinking of it as multiple circles stacked on top of one another, an exploration of the dynamic form is possible.

The sketch model explored how simple ge-ometry can be manipulated as well as how differnt planes can unite and connect.

Exploration of the variations that this form can create reveals how what seems like such a simple structure is quite complex.

Angluar changes, repition of rings and dis-tortion of shape are key contributors to this inticate structure.

SIDE VIEW PERSPECTIVE

To make this Sketch Model the use of thick card created a depth to the material which was not overwhelming to the overall struc-ture.

The placement of each ring / cirlce is aimed to represent the natu-ral falling pattern which would occur if permanently combined.

RESPONDING TO PERSONAL SPACE

EXTENSION / JOURNEY / DEVELOPMENT / CONNECTION / FLUCTUATION

Sketch Design #1

One’s personal space varies depending on who or what is around them. These differences are represented in this de-sign through fluctuations of circular panels encasing the body. The set of panels, each variance of form represent-ing a ‘gorup’ (i.e partner/family, acquaintance, stranger), will show the journey of personal space and how the con-nections one has with others can develop this concept.

Section of circular panels connected to a thin mem-brane. This takes on an ab-stracted form of a slinky.

Analysis of how there is a variance in exten-sion. This aspect took in-spiration from the slinky.

Different panels allows more than one type of relationship to personal space to be explored.

Sketch Design #2

RESPONDING TO PERSONAL SPACE

The wrapping of a thin material, in a helix format, around one’s body can interpret the variances of personal space. By enclosing the system, it creates a barrier from the ‘out-side’ world. This design looks at how one personally feels about space as it responds to their sensitivities. The dis-tance from the body and regularity of loops varies depend-ing on whether its a point of stress that needs protecting.

Personal space barriers are able to be differed depending on where on the body it is represent-ing. This section shows how the material can be manipulated to different lengths and intervals.

Plan view of this design allows the element of a helix to be ex-plored. The formation is deformed from a regular helix in order to incorporate the need for dif-ferent levels of personal space.

Sketch Design #3

ENCLOSURE / GROWTH / ADAPTION / EMOTION / TRANS-

RESPONDING TO PERSONAL SPACE

This design explores how personal space can be adapted. The emotional state of a person and their environment can trigger varied needs for personal space. These different levels can sometimes be difficult to accomplish; this neck design the aim was to be able to transform and extend the object to de-fine one’s need for space, for example, if the need for person-al space increases, enclosure is available through extension.

Plan view show the cir-cular form inspired by the slinky. The hollow, cylindrical shape cre-ates an enclosed, pri-vate space for a person.

Elevation reveals how one can use the nexk piece when not in need of private personal space. This concept is free and adaptable.

Side view shows the dy-namic nature of the design as it is able to transform and twist to a persons desire to achieve personal space.
