What does CAD stand for
Computer aided design
What is crowdfunding
crowdfunding is where people can back a project up by funding money
Ways of virtual marketing
Instagram, google etc
what is cooperatives
Cooperatives are organisations with lots of people working together towards common goals
what is fairtrade
Fair trade is a trading partnership that ensures workers in developing countries are given suitable working conditions and are paid a fair wage.
what are the 5 finite resources
Fossil, crude oil, gas, coal, nuclear fuel
what are the 6 non-finite resources
hydro-electric, tidal energy, solar energy, wind energy, biomass, geothermal
What is kaizen
continually making small adjustments to production techniques to improve speed and quality and save resources.
What is market pull
Market pull is when product ideas are produced in response to market forces or customer needs.
What is tech push
Research and development in science and industry can lead to new discoveries, which can be used to improve existing products or develop new ones.
what is FMS
Flexible manufacturing systems (FMS) are a series of different machines producing different parts for a product. The system is flexible because, at any time, machines in the process can be reprogrammed to change their task and production can be changed to produce more or fewer parts without stopping the other areas of the process.
What is just in time
Just in time (JIT) manufacturing is triggered by a customer order. The correct amounts of materials are ordered in to cover the order, and these arrive just as they are needed by production. This saves money on storage, reduces waste and ensures there is no money wasted producing stock that will remain unsold. There are disadvantages to the system in that, if any part of the product cannot be sourced, clients have to wait for their order to be produced.
What is lean manufacturing
Lean manufacturing is a Japanese concept, based on minimising costs and maximising efficiency by cutting down on waste and the amount of materials and energy used in production. This is done by adapting designs and making changes to the production process. For example, to reduce waste, a packaging net could be redesigned to include a tessellating pattern or, to improve efficiency, changeover times between production runs could be reduced.
What is planned obsolescence
a product is designed in way that it is meant to break after a time span
state 3 examples of modern materials
Concrete, aluminium and steel
What is a nanomaterial
Nanomaterials are tiny particles of 1 to 100 nanometres (nm)
What is LCD
Liquid crystal displays (LCDs) use the light-modulating properties of liquid crystals to display an image.
why is oled expensive
which allows devices to be thinner and lighter. OLEDs are more expensive as each pixel is its own light, but they allow for thinner panels and better colour and contrast.
how do you class a material in smart material
they need to exhibit a physical change in response to some external stimuli.
What is SMA
Shape-memory alloys (SMA) are metal alloys that can remember their shape when heated.
Example of SMA
nickel titanium
What is thermochromic pigments
Thermochromic pigments change colour when their temperature changes.
What is photochromic pigments
changes colour when exposed to light
What is QTC
Quantum-tunnelling composite (QTC) is an insulating rubber containing tiny particles of metal. When squashed, the metal particles meet and allow the flow of electrical current.
