Physical Modelling
Essential Idea: A physical model is a three-dimensional, tangible representation of a design or system
Designers use physical models to visualize information about the context that the model represents. It is very common for physical models of large objects to be scaled down and smaller objects scaled up for ease of visualization.
- can be used to obtain important data such as test and simulation measurements
- allows the user to better understand the problem
- allows for manipulation and changes to design
- observations with the internal structure or external structure
Scale Models :
a model that is either a smaller or larger physical copy of an object
- accurate physical representations of objects or features of objects
- able to allow the design team, client, or manufacturer visualize and/or manipulate the object
- scaled down or up; keeping all sizes of the features in relation to each other
- visualize the structure and form of an object
- unforeseen factors are highlighted
Aesthetic Models :
a model developed to look and feel like the final product
- An aesthetic/appearance prototype
- Not functioning
- Concerned with form, color, style, texture, and how the product fits in its visual environment
- Can be used for ergonomic testing, evaluating visual appeal and matching manufacturing systems
- Can be more complicated and stimulate weight
Mock-ups:
a scale or full-size representation of a product used to gain feedback from users
- used to test ideas and gather feedback
- can be full-scale or scaled models
- can have some level of functionality, can also be considered a prototype
- a good example of how design begins and gets to the mock up stage
- saves costs by avoiding going into production with a design which needs improvement
- used to determine proportions / fitting into spaces
- can be used for promotion
