• Market pull


  When users want a product to be improved or redeveloped to meet their needs
• technology push is where new technology or materials are developed and the designers take this as an opportunity to design a new product
• an example of technology push is electric cars
• an example of market pull is whatsapp users wanting new emojis and getting them
• culture is the values, beliefs and customs used by groups and societies to interact with one another
• an example of a cultural group could be an ethnic group, political group or religious group
• the 4 stages of product lifestyle are: introduction, growth, maturity and decline
• automation control is often used in production lines, communication networks and guidance systems
• CAM stands for computer-aided manufacture
• CAD stands for computer-aided design
• examples of CAM are: laser cutters, 3D printers and CNC routers
• examples of CAD are 2D design, SketchUp, fusion and solid models
• how is windpower generated?

  windpower is generated by wind turbines
• where are wind turbines most likely to be found?

  in areas that are open plains with high wind pressure
• what are the types of renewable energy?

  wind power, hydroelectricity, solar, geothermal
• solar energy is generated using solar panels in open plains and areas of high sunlight
• geothermal energy is made using fluids drawn from the earths crust through wells
• hydroelectricity is generated through the use of water to turn a turbine which produces electricity
• bioenergy is created by burning biomass, such as wood, to produce electricity or heat
• what are the stages to using a wind turbine?

  wind pushes the turbines round, forming kinetic energy which then gives the storage electrical energy
• the types of energy storage are: thermal energy storage, pumped hydroelectric and batteries
• what are the types of energy?

  Kinetic, potential, thermal, light, sound, electrical and chemical energy
• define planned obsolescence?


  deliberately designing the lifecycle of a product to be short, forcing the user to update their products
• planned obsolescence is when a product is designed to be short-lasting, forcing the owner to buy another
• examples of planned obsolescence are vapes, phones and cars
• product analysis means to study how well a product does its job, how sufficient it is
• what does product analysis identify?

  it helps to identify flaws and useful features
• product analysis is used by designers to see how different products work
• designer responsibility is how products have to accommodate many cultures
• CAD stands for computer aided design
• cad is used to create precision with technical drawings and models
• cad is used often by architects, designers and design professionals
• what are 3 main advantages of cad?

  it doesn't waste any paper, it achieves precision and mistakes can be undone
• what are the main 3 disadvantages of using CAD?

  they have security issues as they are online, very expensive and they require training
• What is this cycle is this ?
