Core content Flashcards
What is automated production?
A production method of using machinery controlled by computers.
What does CAM, stand for?
Computer-aided manufacture.
What is demographic movement?
When people move to different countries to find employment where there is a shortage in a particular workforce.
What is enterprise?
A privately owned business is owned by the company founders or by families or investors.
How can you get funded?
By crowdfunding, business investment, and government funding.
What is sustainability?
Meeting today’s needs without compromising the needs of the future generations.
What is finite?
Resources with a limited supply that will eventually run out.
What is non-finite?
Resource that will not run out.
What are the 6 Rs?
Rethink, Recycle, Repair, Refuse, Reduce, Reuse.
What is carbon footprint?
A measure of the greenhouse gases emitted by human activity.
What is ecological footprint?
The measure of the impact that humans have on the environment.
What is ecological deficit?
When resources are used faster than nature can replenish.
What is obsolescence?
Process of becoming no longer wanted or needed.
What is migration?
The movement of people often to find work.
What is the internet of things (IoT)?
The interconnection of everyday products to the internet.
What are finite fossil fuels?
Fuels that have a limited supply and cannot be replaced. For example oil and coal.
What does biodegradable mean?
It will decompose (rot) and break down without damaging the environment.
What does production depend on?
Type of product being made.
Quantity required.
Timescale for manufacture.
What is one-off production?
A single product is manufactured for a specific client need.
What is batch production?
A set number of identical products is produced over a set period of time.
What is mass production?
Very high volumes produced over an extended period of time to meet the demands of mass marketing.
What is continuous production?
High volume of production; manufacturing is a non stop through 24-hour period.
What is just-in-time manufacturing?
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.
What is lean manufacturing?
It focuses on minimising waste in all areas of design through to manufacture, while maximising productivity at the same time.
What does synthetic mean?
Human made.
What is nitinol?
Alloy of nickel and titanium
What is an alloy?
A metal mixed with another metal or element to improve its properties in some way.
market pull.
responding to demands from the market.
technology push
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.
The Product Life Cycle.
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.
Employment law
involves keeping the employees safe and ensuring that employers are fair.
Consumer law
involves protecting consumers and anyone purchasing products and services.
Intellectual property laws
involve protecting ideas, creations, designs, names and logos.
Advantages and disadvantages of using computer aided design (CAD).
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.
Advantages and disadvantages of the use of computer aided manufacture (CAM).
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.
Renewable energy sources for products.
wind-up and photovoltaic cells.
Quantum Tunnelling Composite (QTC) -
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.
Electroluminescent film.
a thin copper wire that is coated in a (light-emitting) substance., which glows brightly when a current is applied to it.
MICRO‐ENCAPSULATION
Tiny bubbles that contain scent or chemicals are
incorporated into materials.
activated with heat or friction.
THERMOCHROMIC INKS
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.
.
PHOTOCHROMIC DYES
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.
Carbon Fibre, Kevlar and GRP.
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.
Microfibres
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
Breathable materials
Fabrics such as Gore-Tex that have a permeable
membrane that manages the flow of moisture
appear to be breathable.
Rhovyl
Rhovyl is a synthetic fibre that is antibacterial,
waterproof, crease resistant and quick drying.
* It does not retain odour.
* Ideal for use in sportswear
cam mechanism
a cam - attached to a crankshaft, which rotates
a follower - touches the cam and follows the shape, moving up and down.
Explain the term ‘interactive fabric
fabric that has a circuit built into it
will respond to the user by communicating the
effectiveness of physical activity.
