17
Q

What is one-off production?

A

A single product is manufactured for a specific client need.

18
Q

What is batch production?

A

A set number of identical products is produced over a set period of time.

19
Q

What is mass production?

A

Very high volumes produced over an extended period of time to meet the demands of mass marketing.

20
Q

What is continuous production?

A

High volume of production; manufacturing is a non stop through 24-hour period.

21
Q

What is just-in-time manufacturing?

A

It is a stock control system where components, parts or materials are ordered when needed. It is efficient and cost-effective but is highly reliant on suppliers delivering on time.

22
Q

What is lean manufacturing?

A

It focuses on minimising waste in all areas of design through to manufacture, while maximising productivity at the same time.

23
Q

What does synthetic mean?

A

Human made.

24
Q

What is nitinol?

A

Alloy of nickel and titanium

25
Q

What is an alloy?

A

A metal mixed with another metal or element to improve its properties in some way.

26
Q

market pull.

A

responding to demands from the market.

27
Q

technology push

A

A technology push is a new invention that is pushed onto the market without – sometimes without considering whether or not it satisfies a users need.

28
Q

The Product Life Cycle.

A

Introduction -paying for a new product to be advertised and launched while sales are low
growth - sales increase as it becomes popular with consumers
maturity - a competitive time-product has reached out to all customers-well known, continued competition as newer products are being released, keep sales high through marketing.
decline - product sales decrease as new competitive products come to market.

29
Q

Employment law

A

involves keeping the employees safe and ensuring that employers are fair.

30
Q

Consumer law

A

involves protecting consumers and anyone purchasing products and services.

31
Q

Intellectual property laws

A

involve protecting ideas, creations, designs, names and logos.

32
Q

Advantages and disadvantages of using computer aided design (CAD).

A

Advantages-Ideas can be drawn/developed quickly
Designs can be viewed from all angles.
Some testing and consumer feedback can be done before production.
Disad- Expensive to set up.
Needs a skilled workforce.
Difficult to keep up with constantly changing and improving technology.

33
Q

Advantages and disadvantages of the use of computer aided manufacture (CAM).

A

Advantges- Fast and accurate production.
Good for producing on a mass/flow production line.

Disadvantges-Expensive to set up.
Needs a skilled workforce of engineers.

34
Q

Renewable energy sources for products.

A

wind-up and photovoltaic cells.

35
Q

Quantum Tunnelling Composite (QTC) -

A

black rubbery material which is an electrical insulator, but when placed under compression, it becomes a conductor. It is used in clothing, smart phones etc.

36
Q

Electroluminescent film.

A

a thin copper wire that is coated in a (light-emitting) substance., which glows brightly when a current is applied to it.

37
Q

MICRO‐ENCAPSULATION

A

Tiny bubbles that contain scent or chemicals are
incorporated into materials.
activated with heat or friction.

38
Q

THERMOCHROMIC INKS

A

Clothing that change colour according to wearer/environment.
They react to changes in temperature
The inks-colourless
heat turns it into a vibrant colour once activated.
.

39
Q

PHOTOCHROMIC DYES

A

change colour when exposed to Ultraviolet
sunlight.
alter from colourless to intense colour after only 15 seconds in direct sunshine.
indication of how much UV rays the wearer/user is exposed to.

40
Q

Carbon Fibre, Kevlar and GRP.

A

Kevlar is a tightly woven fabric that has great impact resistance. It is used in racing tyres, racing sails.
Carbon fibre- high tensile strength, low weight, high temperature tolerance and resistance to corrosion.
Glass Reinforced Polymer (GRP) is also called
fibreglass.
Fibre strands are embedded into a polymer resin matrix, resulting in high compressive/tensile strengths.

41
Q

Microfibres

A

they are difficult to see with the naked eye.
they are lightweight with good draping qualities and are made into silk-like fabrics.
Eg-tactel - a nylon-based fibre, not absorbent

42
Q

Breathable materials

A

Fabrics such as Gore-Tex that have a permeable
membrane that manages the flow of moisture
appear to be breathable.

43
Q

Rhovyl

A

Rhovyl is a synthetic fibre that is antibacterial,
waterproof, crease resistant and quick drying.
* It does not retain odour.
* Ideal for use in sportswear

44
Q

cam mechanism

A

a cam - attached to a crankshaft, which rotates
a follower - touches the cam and follows the shape, moving up and down.

45
Q

Explain the term ‘interactive fabric

A

fabric that has a circuit built into it
will respond to the user by communicating the
effectiveness of physical activity.
