Mock-ups, models and prototypesMock-ups, models and prototypes
What are mock-ups, models and prototypes?
These are examples of what the final product might look like. They are usually 3D, but can also be 2D drawings.
Models are used to show clients or customers elements of a design to help make it easier to understand a concept. For example a car manufacturer would produce a prototype of a new car – a life size working model that can be used for testing, development and evaluation. It can also test market interest.
MODEL: A graphic presentation of the item you are designing. It is often a scaled down (smaller) version of the design.PROTOTYPE: A life size (scale 1:1) working model of a design, used for testing, development and evaluation. MOCK-UP: A model, often full size, of a design to allow for evaluation; a working model of a product built for study, testing or display.
ScaleScale
During the design process, manufacturers will make a model, mock-up or prototype. This does not have to be actual size however.When designing a new shop for instance it would be difficult to show potential customers a life size model of the new shop, therefore the manufacturer would make a model of the shop.
It is important to make sure the scale of the model is appropriate for the design.Usually you would design spaces such as shops, cafes, buildings 100 times smaller than in reality. The scale would therefore be 1:100.
Examples of scales are below:
Scale Uses
2:1 Twice full size A small intricate item, such as an earing.
1:1 Actual size A hand held object, such as a mobile phone.
1:2 Half size A small electrical device, such as a laptop computer.
1:10 A piece of furniture
1:100 A house or garden
1:500 A very large building, such as a sports stadium.
