Craft and DesignSupport Materials: Factors that Influence Design

Introduction

This resource covers the factors that influence the design of products.

esthetics and Ergonomics have each been covered in separate boo!lets as they re"uire more

detailed consideration.

#hen designing products the designer has to $%uggle& 'ith a large number of factors and attempt

to organise them in the design solution in a 'ay that satisfies the design brief and specification.

professional designer 'ith many years of e(perience 'ill be able to balance the factors

intuitively. Students of design must ta!e more care to consider all the relevant factors ) perhaps

by using a chec!list.

n e(cellent illustration of ho' the designer handles these factors is given by Dic! *o'ell in the

E"uino( T+ programme ,$Designing Dream -achines&. ere the process is described as /ane(plosion in reverse0.

#hen considering fitness for purpose the designer should begin by establishing a chec!list of

features that are essential and desirable. On completion the design must be able to achieve allessential features. ny desirable features the product has 'ill be a bonus and may assist in

placing the product above its competitors in the mar!et place.

Question

Choose a simple household product and describe in what way it is and is not suited to itspurpose. A sketch of the product should accompany your answer to illustrate the points made.

Choice of Materials

#hen choosing the materials for a product the designer must consider a number of factors

use of product

"uantity to be manufactured

mar!et niche 6cost7

Use of the product

The choice of material has to ta!e into account ho' the product2component 'ill be used and

'hat environment6s7 it 'ill be used in. Ta!e for e(ample a plastic 'ing mirror body for a car.

The plastic chosen 'ill have to 'ithstand 'ear and tear from stone chips etc. 'ashing 'ithdetergents1 sharp !noc!s from passing vehicles and at the same time tolerate temperatures from

sub)5ero to over 899: C. On some vehicles this component is painted to match body colour

therefore material 'ill also have to accept paint.

Quantity to be manufactured

Some products could be manufactured in more than one 'ay. Often the decision depends on the

"uantity to be manufactured. -etal castings for e(ample can be made one at a time by sand

casting or produced in high volume by die)casting. lthough sand casting is labour intensivetooling costs are relatively lo' and so this process is ideal 'hen small numbers are to be

produced1 say less than 899. s soon as volume increases into hundreds or thousands a more

mechanised process becomes more appropriate 6die)casting7. ere tooling costs are very high )but as long as volume is high enough the cost of producing a single item becomes very lo'.


6/27

Market Niche

nother factor in choice of materials can be the end cost of the product. If the product being

designed is at the bottom end of the mar!et 'here cost is very important then the material has tobe as cheap as possible. s long as the material is able to carry out its function for a reasonable

period them it 'ill be deemed satisfactory. o'ever 'ith an up)mar!et product cost becomes

less of an issue. -aterials chosen should perform 'ell1 should be long lasting and reflect the"uality image of the product.

Question

When choosing materials for a product the designer has to consider

use of product

quantity to be manufactured

market niche

Choose one household product and discuss how these three factors will have affected the choice

of materials.

Finish

The choice of finish of a product is influenced by similar factors to those affecting the choice ofmaterials1 i.e.

use of product

"uantity to be manufactured

mar!et niche

Question

A designer has designed a gardening trowel. The trowel is designed for the cheaper end of themarket but is to be sold in superstores that have a reputation for selling inexpensive products

that are of good quality. Discuss the factors the designer will have to consider when selecting a

finish for this product.


7/27

urability

Durability of a product or component depends on a number of factors;

planned obsolescence

use of product mar!et niche.

The durability of a product2component depends directly on the materials chosen1 the

manufacturing process used and fi(ing methods employed 6see section on selection of materials7.

In a sense it is planned obsolescence 'hich is the !ey factor as it is this that dictates the

performance of the product2component 6see section on obsolescence7.

aving decided on the intended life span of the product1 the designer must define the mar!et

niche and the use of the product 6see materials section7.

This should lead to a definition of the properties re"uired of the product1 and hence the choice ofmaterial.

!ase of Maintenance

-aintenance of a product is a factor that can easily be overloo!ed. t the forefront of thedesigner&s mind 'ill be function and aesthetics. #hilst maintenance is an aspect of function1 it

is secondary to function in use.

Consideration of maintenance depends to a large e(tent on the life e(pectancy of the product. cheap do'n)mar!et product 'ill often sacrifice maintenance to cost. In this instance thedesigner intends that the product 'ill be thro'n a'ay 'hen it ends its useful life.

In contrast1 more e(pensive up)mar!et products 'ill generally have much longer life e(pectancy

and therefore may re"uire periodic maintenance to maintain optimum efficiency of the product.

3uilding in maintenance obviously adds to the cost of the product but can be %ustified in highercost products.


8/27

Question

n the design of a family saloon car the design of the clutch can be such that replacement can be

done quickly and easily but this adds cost to the vehicle. Assuming typical clutch replacementafter ! years use" discuss the factors the designer will have to consider.

!fficiency

The efficiency of a product in use depends directly on the "uality of the product. One 'oulde(pect that a cheap do'n)mar!et product 'ould serve its purpose1 but only %ust. In contrast1 one

'ould e(pect a high "uality product to fulfill its function 'ith ease giving the user pleasure in itsuse 6see section on fitness for purpose7.

cheap !ettle 'ill boil 'ater. more e(pensive model 'ill boil 'ater "uic!ly1 use less energy1be aesthetically pleasing and so on.

The designed efficiency of the product 'ill depend upon its intended mar!et niche.

Question

A man buys a disposable ra#or. $e finds the ra#or unpleasant to use and the quality of the shave

isn%t good. Discuss in terms of efficiency whether or not this product can be considered gooddesign or not.

"unning Costs

To the consumer1 the running costs of a product may or may not be an issue. o'ever the

designer must consider this factor balancing it 'ith all other factors in relation to the intended

mar!et niche.

In general1 'ealthy individuals buy products 'ithout considering secondary factors such as

running costs. Their primary concern 'ill be factors such as efficiency and aesthetics.


9/27

The less 'ealthy individual 'ill be much more concerned about running costs. Running costs

are generally made up of energy2fuel use and maintenance. To reduce running costs it is not

uncommon for less 'ealthy individuals to carry out their o'n maintenance.

Question

When buying a cycle lamp a teenager can choose between a cheaper model with disposable

batteries and a more expensive version that has rechargeable cells but is more expensive.

Discuss the issues the teenager will have to consider in making a choice.

Fashion

*roduct Design li!e all other areas of creativity follo's patterns or trends in style. These trends

are closely lin!ed to fashion.

Throughout design history there have been very distinctive styles that can be lin!ed to a period in

time.

Each one of these styles 'as fashionable during the periods indicated and has features that ma!eeach one easily recognisable1 as can be seen in the e(amples belo'.

11/27

Today products are available in many different styles. Designers are able to emulate styles of the

past and manufacturers produce these products using modern materials and manufacturing

processes e.g. Retro Car 6only available in apan7 produced by ?issan 'hich is in the style of a8>@9&s model. This approach to design actually produces a ne' style 'hich could be considered

the style of the 8>>9&s. In addition designers are also able to utilise modern technology to

produce totally ne' styles that 'ould not have been possible in the past.

The trend in the 8>>9&s then seems to be to mi( styles1 often to render these styles in ne'

materials in a functional manner. Colour and decoration tend to be subdued 'ith combinations of

igh Tech and Traditional materials being used together e.g. *astel coloured in%ection mouldedplastic 'ith galvanised steel or brushed aluminium creating a very subtle contrast as used in the

Dr Globb chair designed by *hilippe Star!.

n increased concern over the environment has also influenced today&s products. -any ne'

products are designed to be easily recycled e.g. -!. III +ol!s'agen Golf. Often products aremade from recycled materials. This has in itself become fashionable.

Designers can ta!e advantages of fashion trends to design products that fit into a particular

mar!et $niche& 'hich has been identified by mar!et research. lso since trends tend to change"uite rapidly it is possible for designers2manufacturers to cash in on these changes by updating

products in !eeping 'ith the latest fashion. -otor car manufacturers do this by producing limited

edition models in special colours and styling details. Clothing manufacturers use the changingseasons 6spring1 summer1 autumn and 'inter7 to encourage people to buy ne' clothes. Each ne'season creates the opportunity for designers to introduce a ne' style or colour. Designers also

use trends set by pop groups or cult figures to create ne' fashions.

#afety

-any products have to be designed to comply 'ith regulations laid do'n by la' or by

recommendations made by organisations such as 3SI 63ritish Standards Institution7 and ISO

6International Standards Organisation7. Often ISO1 3SI and the Government 'or! together to set

standards. The government 'ill for e(ample state that car seat belts must be fitted to all cars andthat the belt design should be to 3SI2ISO standards. #hen a product is manufactured to these

standards it 'ill be clearly indicated that this is the case some'here on the product 'ith anumber and the 3SI2ISO logo.


13/27

The designer of a product is responsible for ensuring that products are safe to use. There are a

number of 'ell documented cases 'here designers have been sued for negligence1 i.e. designing

a product 'hich proves to be unsafe and causes in%ury to the user. The driver 'as badly burnt1sued the designer and 'on. s a conse"uence of such cases designers must ma!e every effort to

design products that 'ill be safe in use by carrying out stringent functional tests.

Occasionally products are found to be unsafe after they

have been put on the mar!et and have to be redesigned1

e.g. plastic pen tops such as those manufactured by 3ICcaused a number of deaths in young children 'hen

accidentally s'allo'ed. The pen top 'as modified so that

it is open at both ends so that if s'allo'ed the air'aydoes not become bloc!ed.

-bsolescence

#hen designers consider the materials and the method of construction of a product they

obviously have to ta!e into account the follo'ing.

o' long the product should last for.

o'1 and under 'hat conditions1 'ill the product be used1 i.e. function1 durability and

safety.

i!e all factors that influence design these considerations have to be ta!en along 'ith all others.

In many instances it is possible to design product that 'ill last a lifetime. Is this necessary or

even desirable4 If a manufacturer designs a product 'hich lasts forever1 say a 'ashing machine1

'hat impact 'ould this have on the manufacturer4 They 'ould not sell so many machines. The

machines 'ould probably have to cost a lot more than current models. The buyer 'ould end up'ith products 'hich are old fashioned but still functioning 'ell. The user 'ould not be in a

position to ta!e advantages in advances in technology by purchasing the latest most

economic2environmentally friendly design.

Designers and manufacturers have therefore to find a balance bet'een profit1 value for money1

durability and at the same time satisfying the customers desire to o'n the latest most fashionable

products. This is called building in obsolescence. i.e. the product is designed to last for a setperiod of time. This allo's the manufacturer to be able to be constantly selling ne' products in

the mar!et place 'hich is good for business and at the same time satisfies the mar!ets desire for

the latest ne' products.

In general 'ashing machines are designed to be replaced after about si( years. Ordinary lightbulbs are designed to last for a ma(imum of si( months of normal use. -ost products then have

a built in life e(pectancy. Often similar products are available 'ith different lengths of planned

obsolescence1 for e(ample up)mar!et cars are designed to last for as long as 89 years 'ithout theneed for ma%or repairs 6'hich is one of the reasons 'hy they are so e(pensive7 against a cheaper

models designed to last for only @ years.

ll products have an impact1 to a lesser or greater e(tent on society. This impact 'ill influence

the follo'ing areas.

Environment ) aesthetic. s a conse"uence of the visual impact of the product in

association 'ith its surroundings

Environment ) pollution. Created by the manufacture1 use and2or disposal of the product

at the end of its life

Social ) physical and social impact of the product on the user and society in general.

!n.ironment / aesthetics+

The designer has the ability to create products in any style. It is possible to design products that

merge 'ell 'ith their environment or alternatively those 'hich stand out in star! contrast to their

surroundings. *roducts 'hich harmonise 'ith their environment are pleasing to the eye but canbe considered to be boring and not stimulating.

For e(ample a designer may choose to design a bus shelter in the Georgian style to match the

surrounding architecture. This approach 'ould blend in 'ell and probably 'ould be acceptableto the ma%ority of people. o'ever this $safe& approach to design can create an environment

'hich is monotonous. lternatively the designer may choose to design the bus shelter to contrast

'ith the Georgian buildings by producing a design 'ith modern materials such as steel andplastic 'ith simple geometric forms and shapes perhaps integrating bold lighting so that the

shelter stands out day and night. This approach 'as ta!en 'hen designing the metro and

subterranean gallery entrance at e ouvre in *aris 'hich is a glass pyramid and is in star!

contrast to the decorative Renaissance sandstone architecture surrounding it. This bold approachto design can be shoc!ing and often attracts controversy particularly in relation to architecture.

Such an approach can be interesting and e(citing to some people and offensive to others. The

designer then has to ma!e a decision concerning the impact that the design 'ill have in order toascertain 'hether or not it 'ill be acceptable to society.


17/27

!n.ironment / pollution+

#hen designing products the designer must consider the effect on pollution levels that their

design 'ill have. The product and its manufacture may also be influenced by legislation 'hichcontrols pollution outputs. This is further complicated by the fact that pollution controls vary

from country to country. There has also been a ma%or shift in public interest in environmental

issues and many people 'ill ta!e this into account 'hen purchasing a product.

t all stages in the development1 manufacture and disposal of a product environmental issues

have to be considered. This also applies to the product 'hen in use. This 'ill clearly have

considerable effect on the final price of the product. et us ta!e the e(ample of the - lll

+ol!s'agen Golf 'hich is advertised as being environmentally friendly.

For this to be the case the follo'ing conditions 'ould have to true.

The use of finite resources should be avoided 'henever possible.

-ost materials used should be recyclable1 say >9J or more.

The processes used to manufacture these materials should not pollute the environment

beyond legally acceptable limits.

The processes used to form the materials into car components should not pollute theenvironment beyond legally acceptable limits.

The processes used to assemble the components should not pollute the environment

beyond legally acceptable limits.

Finishing processes such as painting should not pollute the environment beyond legally

acceptable limits.

The 'aste products from manufacturing processes should not pollute the environment.

#ithin the EEC it is the responsibility of the manufacturer to dispose of all 'aste safely.

The operation and maintenance of the vehicle should not pollute the environment beyond

legally acceptable limits.

The disposal of the product at the end of its life should not pollute the environmentbeyond legally acceptable limits.

It is clear then that these limits 'ill have ma%or implications for the design.


18/27

#ociological considerations

The environment in 'hich 'e live1 'or! and play has a considerable effect on our state of mind

and general 'ell being.

Studies sho' that1 for e(ample1 to simply alter the lighting levels from day to day in a factory

'ill improve the output of the 'or! force. It is not the "uality of light that creates the

improvement but the fact that there has been a change. changing environment is more

stimulating and therefore more motivating.

This e(ample sho's that even very subtle changes to the environment can have dramatic effects

on people. Clearly then1 designers have to very careful 'hen designing the products 'hich shape

our environment. The impact that a ma%or ne'

building has on those 'ho live and 'or! in and around is obvious. *roducts such as computers or

even hair dryers all have a bearing on our general state of mind1 particularly in a society 'herepeople lead very busy lives. The feelings of frustration and even anger 'hen a product 'e are

using doesn&t function in the 'ay e(pected are common place. This contributes to the stress ofmodern day living. #ell)designed products should be pleasing to use they should be reliable and

do the %ob they 'ere designed to do. s 'ell as functioning 'ell their aesthetic 'ill also effect

us.

#hy is it that 'e have feelings of refreshment or contentment 'hen standing on top of a hill on a

glorious day 'ith a spectacular vie' before us4 It is due in part to the fresh air but also the

colours and shapes of the vie' i.e. the aesthetics of the vie' ma!es us feel good. Therefore it isclear that if 'e are surrounded by products 'hich are attractive 6in an aesthetically pleasingenvironment7 then 'e 'ill inevitably feel better 'ithin ourselves. To create this designers have

to create a fine balance bet'een pleasant harmonising products 6'hich in e(treme cases can be

boring7 and bold contrasting designs 6'hich can be irritating7.

In catering for the needs of the individual the designer must consider age1 culture and physical

ability2disability. Each of these aspects 'ill effect the userKs reaction to a particular product.

Often modern $igh Tech& products can be threatening to older people ma!ing them feelinsecure. designer must1 in such situations1 try to ma!e ne' technology as $user friendly& aspossible. Care needs to be ta!en to ensure that products do not cause offence to a particular race

or culture. Even something as simple as the name of a ne' model of car needs to be carefully

selected to ensure that in a 'orld mar!et the name 'hich may be perfectly acceptable in Europeis not totally unacceptable in another continent.


19/27

-any available products do not ta!e into account the problems of the disabled1 old or very

young. In particular handles and s'itches are often too small or too difficult to operate. #ith a

little bit of thought many of these problems could be avoided. Good design should ta!e intoaccount as many users as possible.

Technological -pportunity

*roducts 'hich appear on the mar!et sometimes do so as the result of technological innovation.This is often referred to as technological push. Scientists1 engineers and designers are al'ays

loo!ing for ne' 'ays of doing things and al'ays striving for the ultimate solution to a given

problem. Often ne' technology is stumbled upon in this search. Sometimes the ne' technology

has an obvious application and sometimes not. Sometimes technology is transferred from oneapplication to another.

In other 'ords advances in technology create ne' products and therefore ne' mar!ets.

Sometimes the products are simply better versions of e(isting products but occasionally productsthat have not e(isted before are produced creating a completely ne' mar!et niche.

Consumer emand

Consumer demand1 sometimes referred to as mar!et pull1 produces products that derive from the

demands of the mar!et. In general this demand is identified through mar!et research.-anufacturers and designers are al'ays loo!ing for ne' mar!ets in 'hich to sell their products1

or mar!ets for 'hich they can design ne' products 6mar!et niche7. Specialist mar!et researchconsultancies are constantly gathering data on the re"uirements of the mar!et place. This data is

often gathered through the use of "uestionnaires. It is "uite commonplace to see mar!etresearchers 'ith their clipboards on our high streets particularly on a Saturday. Sometimes the

mar!et research 'ill involve gathering together general information 'hich 'ill be offered $for

sale& by the mar!et research company. lternatively the mar!et researchers may be given aspecific area to research for a client. ny designer2manufacturer that does not carry out thorough

mar!et research is ta!ing a great ris!. To invest large sums of money in design1 setting up a

manufacturing facility and producing the product 'ithout chec!ing out 'hether or not that it is'hat the public 'ants is very foolish.

classic e(ample of this is the Sinclair C@ 'hich 'asdeveloped by Sir Clive Sinclair. The C@ 'as developed on thebac! of enormous success 'ith personal computers by

Sinclair Industries. The C@ 'as a small electric three 'heeled

vehicle intended to be an alternative to the bicycle. It is true tosay that the C@ 'as e(tremely innovative and technologically

a success. o'ever1 detailed mar!et research 'as not done to

establish 'hether or not people 'ould use such a vehicle. TheC@ did not sell. This error lead to the failure of Sinclair

Industries.

In contrast to this many products have been introduced or redesigned follo'ing detailed

investigation of the mar!et and have been a great success. For e(ample +ol!s'agen introducedthe +# Golf 'hich 'as the first real hatchbac! car. This design satisfied the need for a small

#ocial (eha.iour

Changes in patterns of social behaviour must be consideredby the designer 'hen 'or!ing on ne' products. Factorsthat 'ould have been considered important in the design of

products @9 years ago 'ould not be seen as important

today. Today lifestyles are such that leisure time is veryimportant. Generally both adults in the family unit 'or!.

Therefore tas!s such as coo!ing and cleaning need to made

much "uic!er and easier to do. ence the increase in theuse of products that permit this1 such as food processors

and fully automatic 'ashing machines 'ith combined

tumble dryers. The increase in the use of precoo!ed foods1

free5ers and micro'ave ovens have also contributed toincreased efficiency in carrying out domestic chores.

This has in turn lead to a situation 'here people have more spare time 'hich has increased

demand for home entertainment such as stereo systems1 video and more recently home cinema.in!ed to this desire for good use of leisure time has also seen an increase in the use of

sports2leisure e"uipment such as e(ercise bi!es and sun beds.

!conomics

The motor industry is a good e(ample of an increase in the importance of this factor. t one timethe price of petrol 'as such that the fuel consumption of a vehicle 'as not important. In the late

8>H9&s the price of oil increased sharply ma!ing large gas gu55ling vehicles impractical. This

brought about the development of lean burn engines and an increase in the use of diesel engines'hich are more economical 6diesel fuel is also less e(pensive7. The aerodynamics of cars has


25/27

also been significantly improved. Today it is not uncommon for vehicles to be able to do @9 mpg

compared to A9 mpg or less 'hich 'as the norm before the fuel crisis.

Generally products today are cheaper to buy than in the past. This is largely due to the economiesof scale. -ost products no'adays are produced in large "uantities using manufacturing

processes that are e(pensive to set up but 'hich1 once established1 can produce products "uic!ly

and very cheaply. The more products that are produced the cheaper the price of a single product.

The development of modern materials such as plastics and compositesmeans that highly comple( components1 that may have been constructed

from a number of components in the past1 can no' be made as a single

item by processes such as in%ection moulding.

Designers also ma!e use of standard components to reduce costs.

#hether the product is something as simple as a torch or as comple( as

a motor car1 standard components are available from such things assimple fi(ings 6special scre's1 bolts etc.7 to bulbs1 s'itches1 alternators

and even 'hole engines. The current +au(hall Omega Turbo Diesel is

in fact fitted 'ith a 3-# turbo diesel engine. This practice is effective


26/27

because the standard component manufacturer is able to produce the

parts in large "uantities ma!ing them cheaper.

Savings can also be made by carefully selecting the best material andmanufacturing process for the item being designed. 3ecause most

mar!ets are so competitive the price can not afford to be unnecessarily

high as this could prevent the product from selling. Often manufacturers'ill set up factories in countries 'here costs are lo'. -any products

today are manufactured in countries li!e China 'here labour costs are

very lo'1 compared to Europe1 and efficiency is high.

The price of a product depends on creating a balance bet'een;

-anufacturing costs 6materials and processes7

dvertising and distribution costs

Design and development costs

*rofit1 overheads and reinvestment

*rices set by other manufacturers.
