Zuperzozial is a Dutch company that manufactures a range of kitchenware (plates, cups, serving utensils, and vessels) from biodegradable bioplastic that is made from renewable resources (such as, corn, sugar cane and grain), see Figure 14.
The environmentally conscious kitchenware is stylish and durable. It also has a similar weight, feel, performance and dimensions to existing ceramic products. Zuperzozial are distributing their product through specialist kitchen stores, where they are displayed alongside conventional kitchenware. Zuperzozial needs to sell the kitchenware at a slightly higher cost than conventional kitchenware to recover the cost of the new technology used to manufacture using bioplastics.
Outline one psychological factor the Zuperzozial kitchenware’s designers need to consider.
Explain one advantage of using Finite element analysis (FEA) and one advantage of using physical models for testing the Zuperzozial kitchenware.
Explain one physical property that the material used in the Zuperzozial kitchenware needs to possess.
Explain how Rogers’ characteristics of relative advantage, compatibility and observability help in the diffusion of the Zuperzozial kitchenware.
The design of a car is a process that has many stages. As a result, there can be a large number of prototypes and drawings used.
Some car designers are still using clay to make their first prototype of a new model of car, see figure below.
Explain why digital humans are used in car interior design.
Outline why isometric drawings are often used in car design.
Describe the difference between surface and solid modelling.
List one reason why clay modelling is still used to prototype models in processes such as car design.
Which of the following types of modelling involves using software to create and modify design representations?
