technology and cultural changes Flashcards
socio economic influences
how society and the economy is interact
recognise more effectively the opportunities that exist for the successful development and marketing of products
post WW1
the bauhaus and development of furniture for mass production
uniting art and industrial design
revolutionary approach to designing
encouraged experimentation
large scale wartime adoption of metal tubing as a replacement to wood as wood could be week
MARCEL BREUER - WASSILY CHAIR
WW2 rationing and the development of utility product
severe shortage of many goods
rationing
provide a fair distribution
GORDON RUSSELL RESOURCES USED IN AN OPTIMAL WAY
utility furniture scheme
- initially only available to married couples and those who lost homes in bombing
contemporary times, fashion and the demand for mass produced furniture and decorative products
utility lacked the excitement and design touches people crave for
designs slowly beginning to change
USA designers incorporating new ideas for example loewy
government scared britain left behind
council of industrial design set up 1944
BRITAIN CAN MAKE IT
british consumers not welcoming to streamline
wary of consumerism
desire to go back to pre war normality
created minitarised radios and record players
rapid development of polymer and relating moulding techniques
new opportunities

BILLY BOOKCASE
microelectronics
thermionic valve era of electronics
control and amplify the control of electrical current
limit to range and effectiveness due to large level of consumption and unreliabliltiy
semi conduction devices with the first transistor in 1940s was pivotal for information technology
semi conductive properties of silicon could be employed for electronic switches
opened up miniaturisation - INTERGRSTED CIRCUITS
massive reductions to size
increasing number of transistors makes devices more powerful
how powerful integrated circuits have become
small scale integration 1964 1-10
medium 1968 10-500
large 1971 500-20000
very large 1980 20k-1mil
ultra large 1984 1mil+
impact of microelectronics on designing and manufacturing practice
possible to incorporate powerful microprocessor ICs in CNC machines
computers to carry out high speed calculations
impact of use of microelectronics in products
1950s tv - bulky furniture sized small screen low quality
current tv - slim large screen ultra high definition 3d colour
1950s computer - thermionic valve cicuitry, computers room sized
current computer- very slim and pirtable with IC
impact of PD on other technological advancements and microelectronics
1954 portable radio - carbon zinc battery with four transistors
1963 compact cassette- ten transistors, electro mechanical speed control
1979 sony walkman- stereo AA batteries
1984 sony disc man- digital layer compact disc
glulam
several pieces of timber that are glued together to create strong composite components for use in buildings bridged and other structures - careful choice of laminated enmeshed natural defects in. wood to be eliminated
- better strength to weight ratio
- ease of forming and shaping with lower energy costs
- strength in multiple directions
- sustainable
kevlar
aromatic polyamide artificial fibre that has tremendous toughness and tensile strength due to density and chemical bonds present in its molecular structure
woven into a variety of materials that are strong and light and these woven materials are often combined with various resins into advanced composited materials
bullet proof vests
puncture resistant tires
precious metal clay
microscopic particles of gold silver and other metals that are bound together in a pliable medium so that they can be shaped into jewellery and other products
when shaped wintering process is carried out which means raising the temp until particles fuse and binding medium is turned off
nano materials
nanotechnology involves the precise manipulation of nano materials
created by using particle in the atomic and molecular size range 1-100 nano metres
used in the form of additives in sunscreen and cosmetics
looking into making more advanced nanoelectrionc devices smaller with greater capacity
coating materials and products
GRAPHENE two dimensional form of carbon honeycomb atomic structure
medicine
electrodydraulic forming
single stage forming of complex sheet metal parts uniting a single sided former by the action of a shockwave generated by an electrical spark in a tank of water
advanced 3D printing of metals
selective laser sintering- direct metal laser sintering
laser is used to sinter metal particles together layer by layer to build up the required form
parts that are strong and lightweight
complex internal features like undercuts and internal voids
ONE OFF PROTOYPES
