RO38 TA2: design requirements

Question 1

quantitative

Answer 1

data based on numerical facts

Question 2

qualitative criteria

Answer 2

data based on descriptions observations or opinions

Question 3

one-off production

Answer 3

manufacturing products one at a time

Question 4

batch production

Answer 4

manufacturing of products in specific amounts (a batch)

Question 5

mass production

Answer 5

rapid production of standardised products and components, often on a production line

Question 6

stock forms

Answer 6

the profiles a material is commonly available in

Question 7

metals

Answer 7

metals are processed into ingots then melted down into stock shapes a process requiring very high temperatures, metals are usually denser and more malleable than others

Question 8

metals- alloy

Answer 8

a mixture of two metals

Question 9

ferrous metals and non-ferrous

Answer 9

ferrous-metals or alloys that contain iron
non-ferrous- metals or alloys that do not contain iron

Question 10

plastics-polymers

Answer 10

available in a range of stock forms depending on whether it is a thermoplastic polymer (formed by heat and can be reformed or reused) or a thermosetting polymer (formed by permanent chemical reactions and cannot be reused)

Question 11

wood

Answer 11

wood is available in natural or man-made forms. natural wood is seasoned (carefully dried) and then shaped by wasting. width of sheets are often limited by the tree. man-made boards are produced by gluing either particles of wood or sheets of wood together.

Question 12

wasting

Answer 12

a process that removes material

Question 13

shaping

Answer 13

a process that involves a change in state of the material

Question 14

forming

Answer 14

a process that changes the shape of the material without the change of state

Question 15

joining

Answer 15

a process that is used to attach separate pieces of material together

Question 16

finishing

Answer 16

a process that changes the surface of a material in a useful way, either protective or decorative

Question 17

assembly

Answer 17

a process of fitting components together to make a whole product

Question 18

labour costs

Answer 18

costs of paying people to make the product

Question 19

capital costs

Answer 19

starting costs of setting up a facility to manufacture a product

Question 20

overheads

Answer 20

general costs of running a business, not directly attributed to a particular product or service

Question 21

market pull

Answer 21

when a need for a product arises from consumer demand which ‘pulls’ the development of a new product

Question 22

technology push

Answer 22

when new technology is created it can lead to the development of a new product that are ‘pushed’ onto the market

Question 23

British and international standards

Answer 23

standard conventions- agreed rules that set the standards used for engineering
British standards- standards that products must conform to, produced by the BSI (British standard institution)

Question 24

standard symbols

Answer 24

CE marking is used for products throughout Europe; it means the product meets EU safety, health and environmental protection requirements
UKCA designed to replace the CE in the uk, it is not recognised in the uk market
iso develop standards to make sure products are good quality, safe and efficient
lion mark symbol is for European toy safety standards
0-3 mark means the product has safety concerns for young children

Question 25

planned obsolescence

Answer 25

a policy of producing consumer goods that rapidly become obsolete, due to changes in design or stopping supply of spare parts

Question 26

contrived durability

Answer 26

this is where a product is designed to be unreliable and stop working after a period of time

Question 27

prevention of repair

Answer 27

companies may choose to market products that are intentionally difficult to take apart and repair

Question 28

software compatibility

Answer 28

due to improvements with technology programs may not be compatible therefore any product will eventually become out of date

Question 29

perceived obsolescence

Answer 29

companies highlight the advantages of new products to try to convince their customers their old products are no longer suitable

Question 30

sustainable design

Answer 30

the development of a product that uses environmentally friendly methods to not harm people or the planet

Question 31

circular economy

Answer 31

a system that reduces the impact of materials on the environment by reducing waste and pollution and maximising the reuse of materials

Question 32
