DT in our world Flashcards
What is Technology Push?
development of new or improved products which come from advances in materials, components or manufacturing methods
eg tablets and smart phones, development of graphene as a material
What is Market Pull?
development of new products in response to user demand
eg the mobile phone
Consumer choice - What is the difference between Customer Needs and Wants?
Needs - cannot do without or essential safety features
Wants - something we would like - make customers feel wanted or gives them status eg designer labels
What is Market Research?
asking the target audience about their needs and wants. A successful product listens and provides for these needs and wants
What are Market Trends?
eg fashion, eco, lifestyle, technological trends.
What is a Mass Market and a Niche Market?
mass market - lots of people will buy
niche market - specific group of people interested int he product. eg gardeners for new gardening tool
What is a unique selling point?
makes a product different from similar ones
eg the original iMac stood out due to its shape and style
Dyson vacuum cleaner - no bag for dust
What are the 4 stages of a Product Life Cycle?
Introduction - launch product
Growth - sales grow as people become aware
Maturity - sales reach peak
Decline - sales fall as people have already bought it
Name some products which have been re-designed because of environmental issues?
wind up radios
electric cars
solar panels on calculators and garden lamps
What is Global Warming and Climate Change?
Global warming is caused by the greenhouse effect (caused by greenhouse gases like CO2)
Contributed to by burning fossil fuels, deforestation,
Give some examples of effects of government policies and legislation?
Eco labels Low Sulphur Fuel Unleaded petrol CFC free aerosols 5p charge of plastic carrier bags 2040 ban on petrol and diesel cars
If products don’t conform then companies will be fined
What are the standards associated with Design and Manufacture?
ISO international standards. eg threads on screws, sizes of batteries
BSI - British Standards Institution - technical standards
Kite Mark - comply with safety regulations
CE marking - conforms to European standards
What is Quality Control?
carried out through the manufacturing process to test to see if it works, is within tolerances for size or assembled correctly.
eg some products tested at random, (for matches)
for electrical items every product is tested for safety
What is Quality Assurance?
Involves the whole company not just the finished product.
Companies would consider:
happy work force paid fairly and developed
Safe working environment
Uses recycled materials
No harm to environment
Customer satisfaction
Factors to consider when thinking about Build Quality?
price competition reliability meets consumer expectation brand loyalty how long will it last
What is Planned Obsolescence? also called built in obsolescence
built in a limited useful life
eg mobile phones and light bulbs
Encourages demand but what about the environment?
What is the definition of sustainability?
Meeting today’s needs without compromising the needs of future generations.
Avoidance of the depletion of natural resources in order to maintain an ecological balance.
Renewable vs non renewable resources?
List some facts.
non renewable are finite and include fossil fuels (coal oil gas). Cannot be manmade . We are using them faster than they are naturally produced.
List some factors to consider for Responsible Design?
using renewable energy sources no toxic by-products low CO2 emission of the product transportation distances repair costs welfare of workers in material supply chain recyclable at end of product life
What is CAD?
computer aided design
using software to accurately draw products
advantages:
edit drawings,
3D views,
Aesthetic visual tests - change finishes to see how it looks,
Performance Tests - test virtual models for strength etc, walk through/tour
send to CAM machines
Name the types of Industrial Process?
Mass Production - hundreds of identical products made on a production line. eg cars
Continuous Production - 24/7 eg oil refinery, drink cans, used when demand is high and not many components
Batch Production - eg batch of 100 bricks
Unit or one-off - made one at a time eg bridge, cruise ship
What is CAM?
Computer Aided Manufacture eg CNC (computer numerical control) machines CNC router CNC lathe CNC miller 3D printers laser cutter
Name 4 cutting systems.
Laser cutting - uses high intensity light beam, burns through or engraves
Plasma cutting - uses an electric arc and air jet blows away molten metal
Water jet cutting - high pressure water mixed with abrasive
Milling cutter - rotating cutter
What is a 3D prototype ?
model which can get answers on: feedback from clients functionality aesthetics will it work tested
