Research

Interaction between the Designer, his tools

and the design

Develop tools to help the designer in the act of

exploring alternatives

What is the emerging relationship between the designer

and the tool with Design Space Exploration?

This research is done from two different points of view. The first being

the use of digital tools to create a novel approach to a number of

design task situated in the design of a building. The second that of

the development of new tools and techniques and the conditions in

which they should function within the design project.

5

Design Space Exploration

Design Space Exploration embraces a number of design

methods which all focus on the use of alternatives as act

of designing. The computer’s role is to help the designer to

explore the alternatives.

6

Explorating alternatives

Although the term Design Space Exploration sounds very

contemporary the idea is actually quite old. Design Space

Exploration is basically the exploration of alternatives in a

design process. And that is exactly what architects and other

designers have been doing for over centuries.

Designer & Process

Design Project

Designer wants to design

For a successful integration of design space exploration it is important to consider the designer and his act of designing. What the tools should do is support the designer in his act of designing instead of replacing him.

Building Tools

General

Useful

A tool designed to perform multiple tasks and fit multiple

processes or designers can be considered general and more

likely less useful in a specific design problem. Whereas a more

specific tool can be much more useful but less general.

Using scripting the designer (or the toolbuilder) can close the

gap between the more general software available and the

specific tools needed without writing new software.

General tool + Scripting = Specific tool

Design as a rational problem solving process Reflection in action

The act of designing can be considered working with various

design problems related to the design task. Most of the design

problems reveal themselves during the act of designing.

Design Concept

Digital design and manufacturing is becoming more and

more important in the design process. The integration of

digital design tools is not bound to one specific practice,

it can be found in various design fields amongst which

automotive, aerospace, product and building design. An

improvement in one field can influence the other fields.

Experiment 01

“The diagram is no longer an auditory or

visual archive but a map, a cartography that is

coextensive with the whole social field. It is an

abstract machine. It is defined by its informal

functions and matter and in terms of form makes

no distinction between content and expression. It

is a machine that is almost blind and mute, even

though it makes others see and speak. […] It never

functions in order to represent a persisting world

but produces a new kind of reality, a new model

of truth.”

Gilles Deleuze

Interest in Voronoi Diagrams

Dealing with complexity

Using the internal relations as a design driver

17

Physical Models

An important step in the understanding of Voronoi diagrams

is the creation of a 3-dimensional diagram and explore

what happens on the common planes between the various

volumes.

18

Network-ed Building

The school for digital design requires a different type of

networked structure; the interaction between the different

disciplines and functions needs a distributed network to allow

allogamy and exchange of information and experience.

Decision Making

The alternatives are generated by the computer and presented to the designer. He has to choose the alternative to continue with.

The decision made by the designer is based on “soft” criteria like intuition and experience rather than on hard facts like numerical criteria.

Interest in Voronoi

De�ning Potential

Voronoi for modelling spatial relations

3D spatial de�nition of the program

De�ne Program

De�ne Relations

De�ne Network Relation ModelTool

This experiment rises from the interest to use Voronoi

diagrams as the start for the creative process. The first stage

is to able to generate three dimensional Voronoi Graphs

using the Autodesk Maya software package. The second

stage is determining the potential of the Voronoi Graph in

architectural design and determining the direction for the

explorations of the third stage.

23

From relations to Voronoi

+

By taking the centerpoints from each of the spheres the input for the Voronoi is created. The result of the Vroronoi is a 3Dimentional representation of the relations shown in the common surfaces between the individual volumes.

24

Evaluating Experiment 01

Grain of the Model

For the modelling the relations it is important to define the initial grain of the model: divide the model into individual rooms, clusters of rooms, clusters of functions etc.The choice affects the final outcome of the tool.

What to Model?

There are numerous functions that can be added when modelling the relations. The challenge is to properly define the program on forehand.

37

Concept

There is a difference in cuts. A smooth one where the volume

is completely removed and a rough cut where the volume is

split.

38

Unpredictability of Nature

39

Alternatives

Complete control over the position of each of the individual points. Results look structured.

Much control over the position of each of the individual points by the placement of the attractors. Results look structured.

No control over the position of each of the individual points. Results look random but are not consistent.

42

Details

The complexity of the design implies that there are a large number of totally unique connections. The variation in surface angles and different materials meeting suggest a lot of unique details. By introducing “empty” space in the otherwise hard to connect area’s these connections can be generalized. Rather than creating a new detail for each connection, a modified version is defined.

Final Words

45

What If?

46

Generating alternatives

Important DilemmaThe alternatives are generated using the computer, the decisions are made by the designer. These decisions are often objective and therefor not (yet) to be made by a computer.

47

Evaluating the design methods

Designing Using Design Space Exploration

- it can direct the designer in a direction- the importance of decisions and decision making is more apparent- the alternatives “not chosen” have influenced the final choice

48

Evaluating Voronoi

Voronoi creates an interesting relation to nature which expresses itself in the whole building.

It creates the important atmosphere the designer was looking for in this building.

It is difficult to use any other formal language in relation to the Voronoi. It is a dominant formal language.

Working with Tools

The apparent advantages of digital tools deal with the issues of speed, complexity and visualization.

When working with the tool the designer must be aware of who is in control. The tool should support the designer, if not, the designer should consider leaving the tool.

In the early stages of the design project developing tools can help the designer externalizing his ideas.

51

Who builds the tool?

Designer as Tool-builder- Closest link between knowledge of the design and the tool to build- Lot of knowledge of building tools needed

Developer as Tool-builder- Specialized in building tools; lots of knowledge- No knowledge of architectural design

New Profession- Specialized in tool building- Knowledge of designing- Close link between designer and tool-builder- Designer needs basic knowledge of tool building

Future research areas

Support with complexity

The ability to help the designer deal with complex problems is an useful area of interest for future research. How can a tool support the designer with complex models while focussing on the design project?

Stimulating creativity

The ability to stimulate the designer in his creative process proved to be a powerful application. How can digital tools support the designer in the early stages of the design project?

Sketching using Code

To be able to have a designer who is also a toolbuilder, the designer needs to have a better understanding of toolbuilding. How can we achieve this and can toolbuilding be made more accessible for a designer?
