The development of James
Dyson’s world-beating Dual
Cyclone vacuum cleaner is a
British success story. It unites
design, innovation, technology
and entrepreneurship around a
single personality in a way
which is perhaps unique.

James Dyson’s company has
emerged to establish itself as
the premier league of British
manufacturers. The company
has designed, produced and
marketed Britain’s top-selling
upright and cylinder vacuum
cleaners. In the process it has
become a £100 million
company, the UK’s fastest
growing manufacturer.

Its products are not sold on
price, indeed they are more
expensive than their rivals.
What makes Dyson Dual
Cyclone so distinctive is its
adoption of an entirely new
technology and its commitment
to design as a way to gain
competitive advantage.

People argued that if his
idea really worked, the big
manufacturers would
already have developed it.
Others said that, as a
designer he knew nothing
about business and
marketing. No development
agency would touch the
Dual Cyclone. James Dyson
was prepared to prove
them all wrong.

Such determination was evident
from very early in his career.
While studying at the Royal
College of Art in the late 1960’s
he began working with the
engineer and inventor Jeremy
Fry on the development of a
Seatruck

sector within three years. The
Waterolla plastic garden roller
and the trolleyball boat laucher
followed.

This is the only boat trolley
capable of floating. The design
doesn’t disappear beneath the
water or sink in the sand, it is
much easier to slide into
position under the boat. The
webbing fits any shape of hull
without any risk of damage.

PROBLEMS WITH TRADITIONAL
VACUUM CLEANERS
School Improvement Service
A GTCW project
dyson
JAMES
In 1978 James Dyson first
realised the problem with
bag vacuum cleaners: they
clog and loose suction. He
had the idea for a vacuum
cleaner that used a cyclone
instead of a bag and did not
loose suction. 15 years and
5127 prototypes later,
having been turned down
by all the big appliance
manufacturers, he
launched the Dyson DC01.
THE PROBLEM WITH TRADITIONAL VACUUM CLEANERS
School Improvement Service
A GTCW project
dyson
JAMES
Over a year, the average
home accumulates enough
dust to fill a bathtub. This
dust contains among other
things, decaying human
skin, dust mites, pet hairs
and allergenic particles.
Vacuuming with a
conventional vacuum
cleaner fails to remove all
this detritus.
THE PROBLEM WITH TRADITIONAL VACUUM CLEANERS
School Improvement Service
A GTCW project
dyson
JAMES
Every design project starts
with dissatisfaction with
what already exists. James
Dyson’s mission was to
improve on the clogged bag
of the domestic vacuum
cleaner, whose basic design
principles had been
unchanged for nearly a
century.
THE PROBLEM WITH TRADITIONAL VACUUM CLEANERS
School Improvement Service
A GTCW project
dyson
JAMES
Dyson was frustrated because
his own experiences told him
that conventional bag vacuum
cleaners failed to produce
enough suction to remove dust
properly. Dust is a big problem,
it is full of allergenic particles
which are harmful to children
and people with respiratory
problems
THE PROBLEM WITH TRADITIONAL VACUUM CLEANERS
School Improvement Service
A GTCW project
dyson
JAMES
Dyson recognised that the
reduction in a vacuum
cleaners suction wasn’t due
to the volume of dust in the
bag, but to the fact that fine
dust particles quickly clog
the pores of the bag and
blocks the airflow.
THE PROBLEM WITH TRADITIONAL VACUUM CLEANERS
School Improvement Service
A GTCW project
dyson
JAMES
After cleaning with a
conventional vacuum
cleaner, all of the air in the
room has been filtered
through pet hairs and dead
human skin to produce a
recognisably unpleasant
aroma. The bags
themselves can be a
problem both to fit and to
obtain. They can also
dislodge and tear in the
machine.
THE PROBLEM WITH TRADITIONAL VACUUM CLEANERS
School Improvement Service
A GTCW project
dyson
JAMES
Most of us have complained
about these problems for
years but have simply
regarded them as problems
inherent to vacuum
cleaning. Dyson however
actually decided to do
something about it. He
began to develop a radical
alternative – the world’s
first bagless vacuum
cleaner.

THE DESIGN AND DEVELOPING
PROCESS
School Improvement Service
A GTCW project
dyson
JAMES
When designing a new
vacuum cleaner, engineers
began by writing a brief,
based on their own ideas
and suggestions from users
of previous vacuum
cleaners. When they began
work on the cylinder
vacuum cleaner (DC02)
they wanted to develop a
smaller, lighter, quieter and
more powerful vacuum
cleaner.
THE DESIGN AND DEVELOPMENT PROCESS
School Improvement Service
A GTCW project
dyson
JAMES
This was partly a response
to the need to develop a
cylinder cleaner for new
international markets such
as Japan, as well as existing
markets in Europe. Dyson
also felt that such a
machine would be very well
received by older people
who wanted a powerful and
lighter machine, or people
who had limited storage
space.
THE DESIGN AND DEVELOPMENT PROCESS
School Improvement Service
A GTCW project
dyson
JAMES
Engineers at Dyson started
generating concepts by
quickly producing a large
number of sketches in
response to the brief. This
produces a wide range of
ideas; for example the stair
hugging shape of the DC02
and DC05. A detailed
specification was written
which set out all the key
design features.
THE DESIGN AND DEVELOPMENT PROCESS
School Improvement Service
A GTCW project
dyson
JAMES
Balancing ideas about
function, safety, reliability,
aesthetics and cost is a
complex process. Should
any of these aspects change
for any reason the whole
design could be affected.
During the design process,
engineers make hundreds
of different prototypes.
THE DESIGN AND DEVELOPMENT PROCESS

Models and prototypes are
an excellent way of testing
ideas and getting a good
impression of how the
product might work and
look. Using a variety of
types of prototypes such as
CARDBOARD
( to help break the product
down into components )

INJECTION MOULDING
Polymer ( a type of plastic )
is added to the hopper
(A) The hopper continually
feeds a rotating screw
which is contained within a
heated barrel. The screw
injects the heat melted
polymer into a mould
cavity ( B ) After it has
cooled and set to the shape
it is then ejected ( C )
THE DESIGN AND DEVELOPMENT PROCESS
School Improvement Service

JAMES
Injection moulding is the most
common moulding process used
by the plastics industry. The
process is extensively used for
thermoplastics. They soften on
heating, harden on cooling and
so can be repeatedly processed.
This process is used for mass
production and is capable of
producing very large numbers
of identical complex mouldings.

QUALITY CONTROL
When a component has
been manufactured you
should look to see that
there is as little evidence as
possible of the
manufacturing process.
Visible imperfections
detract from the quality of
the product.
THE DESIGN AND DEVELOPMENT PROCESS
School Improvement Service

dyson
JAMES
The following are all
imperfections sometimes
found on injection moulded
parts:
FLASH – wafer thin material where
the two halves of the mould join
SPLIT LINE – a fine line where the
two halves of the mould join
FEED POINT – this mark is where
the material flowed into the mould
SINKAGE – uneven surfaces usually
found above a rib
DISTORTION – a large area of the
part is twisted or bowed.

Anyone who has seen a
picture of a tornado can
imagine its astonishing
power. Everything in the
path of the twisting air is
sucked up. The Dual
Cyclone follows the same
principle but on a smaller
scale, and with the help of a
1300 watt electrical motor
Dirt-laden air is sucked up
into the vacuum cleaner
THE dyson DUAL CYCLONE
School Improvement Service

dyson
JAMES
The air enters the outer
cyclone chamber at a
tangent. The air spirals
downwards, accelerating to
200mph, creating sufficient
centrifugal force to throw
the larger debris against
the walls of the bin.
THE dyson DUAL CYCLONE
School Improvement Service
A GTCW project
THE dyson DUAL CYCLONE

JAMES
Within the outer cyclone
lies the inner chamber. The
air enters via the shroud at
the top, which only allows
the finer particles of dust to
pass through. This air spins
faster as it twists down the
inner cyclone funnel. The
air reaches a speed of
924mph.
That’s faster than the speed
of sound !!
School Improvement Service
A GTCW project
dyson
JAMES
The centrifugal force
created within the inner
cyclone forces even the
tiniest particles of dust to
spin out. Not even cigarette
smoke can escape.
THE dyson DUAL CYCLONE
When the air leaves the
vacuum cleaner, it is
cleaner than the existing air
within the room and
odourless.

The Dyson DC07 uses the
most advanced cyclone
technology to maintain the
highest constant suction.
The Dyson root cyclone not
only gives constant suction
but has 45% more suction
than the dual cyclone.
Engineers at Dyson
reduced the diameter of
each cyclone to help the
vacuum cleaner to pick up
more dust.
THE dyson DUAL CYCLONE
School Improvement Service

JAMES
The cone shaped cyclone
speeds up the spinning air
to create greater
centrifugal force This
throws the very fine dust
particles out of the air.
Dyson realised that by
spreading the high volume
of air simultaneously
through many cyclones
gave higher suction power
than previous models.

No aspect of a new product
is safe from copying
without a patent. Before
the first Dyson vacuum

James Dyson spent
£700,000 on worldwide
patents to protect his
invention.

Today there are more than
100 registered patents in
the name of Dyson.
Inadequate patent
protection means that
competitors are likely to
come along and take your
idea.

James Dyson found out
how important it is to have
sufficient legal protection
when his concept for an
integral telescopic hose,
which was one feature on
the DC01 was not properly
protected by his patent
attorney and is now used
on most upright vacuum
cleaners.

Dyson also fought and won
a nerve wracking five year
battle against a giant
American corporation to
bring his idea to market.
His US rival had copied his
idea and guessed wrongly,
that Dyson would have
neither the resources nor
the will to pursue the
matter through the courts.

Having won the court case
Dyson was then free to
focus on manufacturing in
the UK. He had been
careful to retain full control
of his invention this time
because he had previously
sold shares in his
ballbarrow to raise cash
and found himself a
minority shareholder.

James Dyson has also
developed a new washing
machine. He asked his
engineers to experiment
with every imaginable way
of washing: with and
without detergent; with
detergent but without
movement; without water
and even by hand to find
out what was wrong with
existing washing machines.
THE dyson CONTRAROTATOR
School Improvement Service

Dyson discovered that
washing garments by hand
produced better results
than single drum machines.
He found that the clothes
were constantly on the
move, they are manipulated
and flexed. Washing clothes
by hand opens the weave of
the fabric and agitates the
dirt more to release it easily
and quickly
THE dyson CONTRAROTATOR
School Improvement Service
A GTCW project
dyson
JAMES
The single drum can only
go round in one direction at
a time, taking the clothes
with it. On each circuit the
clothes drop and flop to the
bottom of the drum.
Without much movement
Dyson discovered that the
clothes tended to tangle or
bundle. With so little wash
action the clothes need an
extended soak in the
detergent.
THE dyson CONTRAROTATOR
School Improvement Service
A GTCW project
dyson
JAMES
To replicate the movement
by hand, Dyson engineers
designed two aligned rums
and engineered them to
rotate in opposite directions
at the same time. The
clothes are much more
active moving in an
infinitely variable dance to
flex the fabric and open the
weave to the detergent.
THE dyson CONTRAROTATOR
School Improvement Service

The larger Dyson drums
allow clothes to spread out
evenly so that the water
does not have to escape
through such a thick layer
of clothes. Therefore less
drying time is needed after
the wash.
THE dyson CONTRAROTATOR
School Improvement Service

dyson
JAMES
The Dyson has a deeper
double drum with a larger
circumference. This creates
greater centrifugal force
for less revolutions, which
means that only 1400 spin
speed is needed to get the
clothes dry.
The Dyson drums also have
more perforations to allow
the water to escape faster.

A single drum has a thick
rubber seal which holds the
drum to the cabinet. As the
drum moves while the
machine is in use, the seal
has to stretch and compress
This rubber seal found on
conventional machines
collects dirt and you have
to pull your clothes over the
seal to remove them from
the machine.

It can also be difficult
loading and unloading
clothes using conventional
machines. If the seal twists
out of shape, water can leak
from the machine.
