design and innovation Flashcards
maintenance
can the product be maintained, can you replace certain parts
e.g dyson allows you to buy parts and replace them
disposal
designers have to consider what materials would be good for disposal and recycling environmental wise as customers are more aware of these issues
why are most products manufactured in third world countries
cheaper labour costs, less legislation as far as regulation, health and safety laws. employee rights and working conditions
what do you have to consider about the costs when designing
how much it will cost to manufacture: components, materials, labour and manufacturing process as it will have a knock on effect to how much it will cost to the customers
above the line features
visible attributes of the product- shape, colour, finish, user interference, feel and texture
below the line features
consumer would have no knowledge of- how the electronics work, type of material, how the components were manufactured, which country it was made in, how it was assembled etc
things to consider when setting the price of the product
is it reasonable? will the consumer buy it? is it competitive compared to others on the market?
what are the four distinct phases of the iterative design cycle
discover, define, develop, deliver
discover
designers look at world in fresh way and gather insight into the problem
define
make sense of possibilities- what matters most? what is feasible? develop clear brief that frames the design challenge
develop
solutions or concepts created, prototyped, tested and iterated
trial and error helps designs improve and refine their ideas, potential solutions produced
delivery
resulting product is finalised, produced and launched
primary specification
essential features a product must have in order to function
secondary specification
desirable things - not essential for function e.g looking nice to attract customers
quantitative specification
specification points that can be measured
qualitative specification
specification points that are difficult to measure and are mostly personal opinion
why is it good to have a specification
-helps designer keep focused on requirements
-refer back- on going evaluation
-final evaluation at end
CAD modelling
drawings created on computer to show clients exactly what it would look like from different angles, finishes and materials- high quality
advantages of 3D modelling
-ideas shown effectively in 3D
-tested in actual situation
-simple models made quick
limitations of 3D modelling
-high quality models can take time, skill and money
primary research
research you directly do yourself
primary research examples
-telephone
-visit people
-test material yourself
-create own questionnaire
secondary research
research that has been done
secondary research examples
-search internet
-look in books
morphological analysis
identifying key features of a product then considering different ways of achieving these features
lateral thinking
thinking of the problem from another angle
qualitative testing
-test finishes shapes and aesthetics
-personal taste (can be difficult to measure)
quantitative testing
-how strong is the material
-test the material underwater to see how long it would last outside
-compare cost of materials
feasibility study
-ensure design worthwhile- reduce development time and costs
-must be commercially viable
-identify suitable materials and technology
