Design Technology Paper 2
Stainless steel
ferrous alloy
mostly containing iron and carbon
high melting and boiling points
tough, hard, corrosion resistant
18% chrome, 8% nickel
melting temperature 1510°
uses
sinks
kitchenware
cutlery
advantages: corrosion resistance, durability and strength, low maintenance, hygienic properties, aesthetic appeal, environmental friendliness, temperature resistance
disadvantages: higher cost, weight, corrosion under certain conditions, metal leaching, poor heat conductivity, difficult to machine, visible surface blemishes, potential for low grade products
Oil based inks
a type of printing ink that uses oil as its base
known for their vibrant colour reproduction, excellent adhesion, and durability
ideal for premium packaging branding
smudge and water resistant - beneficial for packaging or envelopes that may be exposed to weather
commonly used in offset and flexography printing
often preferred in art contexts due to their vibrancy
pricier than water-based inks
slow drying process, which can make them less suitable for daily printing unless necessary
composition typically includes pigments, oil-based solvents, and resins, ensuring rich colour output and long lasting prints
drying process relies on oxidation and absorption, forming a durable, smudge-resistant layer
sustainability is a growing concern, and modern formulations increasingly use eco-friendly vegetable oils, reducing the environmental footprint of traditional inks
oil-based inks still pose environmental concerns due to their reliance on petroleum-based solvents
advantages: rich colour reproduction, durability, versatility, smoother application, environmental impact
disadvantages: clean-up, drying time, fumes and health concerns, yellowing over time, cost, environmental impact
Circular economy
an economic model aimed at minimizing waste and making the most of resources by keeping materials in use for as long as possible
the focus is on eliminating waste pollution, circulating products and materials at their highest value, and regenerating natural systems
this approach encourages practices such as main tenancy, reuse, refurbishment, remanufacturing, recycling, and composting

Marianne Brandt - modernism
was a significant figure in the Bauhaus Modernist movement of the early 20th century
She became the head of the metal workshop at the Bauhaus in Dessau in 1928, making her one of the few women to hold a prominent position in design at the time
Brandt's designs, characterized by their functional and elegant simplicity, reflect the Bauhaus ethos of "form follows function"
Her work includes iconic items like the Kandem lamp and teapots
celebrated for their aesthetic form and usability
Brandt's contributions to modern industrial design and her experimental photography have left a lasting legacy in the field of the design and art.
Recycling labelling
Recycling labels are essential symbols that guide consumers in identifying recyclable materials and ensuring proper disposal, promoting sustainability and waste management
common recycling symbols
mobius loop
most recognisable
signifies that the item can be processed and reused
commonly found on plastic bottles and containers
recycle and rinse
indicates the item is recyclable but requires rinsing or cleaning before disposal
often seen on food packaging to minimise contamination
local authority collection labels
indicate whether the packaging to collected for recycling by authorities
a label showing that 75%+ of local authorities collect the item means it is widely recycled
a label indicating <50% suggests limited recyclability
caps and lids
some labels advise putting caps back on bottles before recycling as small items can fall through sorting screens and be lost in the recycling process
material-specific codes
the number inside the mobius loop (1-7) identify the type of plastic and help recycling facilities sort materials correctly
known as Resin Identification Codes (RIC)
ensuring that different plastics are processed appropriately
importance
guide for consumers
labelling helps consumers understand how to sort and dispose
reducing contamination in recycling streams
improving overall recycling rates
promoting sustainability
providing clear information on recyclability
encourage responsible waste management and support efforts to reduce landfill waste
local variability
not all packaging will have a recycling label
recycling can vary by location
consumers must check local recycling guidelines to ensure proper disposal
Six sigma
aim: design products with quality built in from the start
Focus: Reduce variation, meet customer needs
key principles
voice of the customer (VOC) - gathering feedback and conducting market research to inform design decisions
data-driven decisions - ensuring that decisions are based on empirical evidence rather than assumptions
proactive problem prevention - helps minimize costly redesigns and recalls
methods
DMADV
Define, Measure, Analyse, Design, and Verify
used to set project goals, identify customer requirements, and develop designs that meet those needs
IDOV
Identify, Design, Optimize, and Validate
emphasizes optimizing designs and validating them against customer requirements.
benefits
reduced costs
improved customer satisfaction
faster time to market
enhanced innovation
Fairtrade
this movement seeks to address the exploitation of framers and craftworkers in developing countries
fairtrade organization negotiates with buyers to secure fair prices for products
qualifying products display a certification label called the Fairtrade mark
Traidcraft is a Fairtrade organization that sells ethically sourced products
Organizations such as schools and local authorities seek Fairtrade mark status to promote:
sustainable development
benefits for producers
active citizenships
increased demand for Fairtrade-accredited food and craft
Pushpanjali, in India, is an example of a Fairtrade organization providing sustainable work for craftsmen and women, as well as many other social benefits
