Dyson Vacuum Cleaners

The Design Brief

In 1978 James Dyson noticed that the bags on standard vacuum cleaners quickly clog with dust reducing suction and efficiency.

He invented a bagless cleaner using cyclone technology to solve the problem.

Sketching

Sketching is a quick and cheap way

of working through ideas and

communicating those ideas to the

design team.

Design engineers create many

sketches in a short space of time.


Test Modelling

Card model Breadboard model

Blue foam model

Catch test rig Resin Cast model

Dyson design engineers move as

quickly as they can from the initial

brief to working in 3D. They make

prototypes out of many different

materials.

They often work in cardboard as this

allows them to make 3D models very

quickly, cheaply and easily.


Computer Aided Design

CAD is a useful tool at this stage as

it means you can begin to construct

an accurate model with precise data,

which can then be used for other

processes such as rapid prototyping

and, later on, tooling.


Rapid Prototyping

Dyson uses a rapid prototyping

process called fuse deposition

modelling (FDM).

It means that accurate plastic

components can be made in a very

short period of time – overnight in

most cases.

Colour

Dyson vacuum cleaners come in arange of different colours dependingon the different models. However,different coloured plastics havedifferent properties and react indifferent ways.

This means that Design engineershave to decide on colours before theprototypes are tested.


Testing

Rigs are developed to test every

aspect of the design e.g. the wheels

the catches the hinges and of course

the cyclone to make sure that the

product will be tough enough to

withstand daily use.


Tooling

When the design engineers have

tested every component and are

happy with their working prototypes,

then the CAD data is sent to the

toolmakers, in order to make the

injection moulding tools. The tool for

each component is made from a

huge block of steel, and costs

thousands of pounds to make.


Quality Control

The first parts back from theToolmakers are inspected verycarefully to check their quality. If any of the imperfections are obvious, then the tool will have to be adjusted.


Assembly

Right at the beginning of the design

process, at the cardboard modelling

stage, design engineers were

thinking about how their product

would finally be assembled. The

less parts a product has, and the

easier they fit together, the quicker

and more efficient the assembly

process.
