Topic 3.3: Physical modelling Flashcards
Physical modelling
the creation of a smaller or larger tangible version of an object that can be physically interacted with
Role of physical models
provide information about
- ergonomics and fit
- relationship between internal and external structure
- aesthetic considerations
Scale models
a smaller/larger physical copy of a model
adv: can be larger than actual product to convey details, can be smaller to save material and time
Aesthetic models
developed to look and feel like final product
adv: evaluates aesthetic appeal, similar to final product, can be used for client feedback
Mock ups
A scale or full sized model of an object used to gain feedback from users (2D or 3D)
may be considered a prototype if it has some functionality
adv: communicates form and proportion, if its low fidelity its quick to make
Prototype
a sample or model built to test a concept or process or to act as an object to be replicated or learned from. can be developed at a range of fidelity for different contexts
Instrumented physical model
prototypes that are equipped with the ability to take measurements to provide accurate quantitative feedback for analysis
adv: real time data, precise measurement, understand how physical forces act on a design
Fidelity range
low: conceptual representation analogous to an idea, intangible and not durable, basic info on form, shape and function
medium: communicate some but not all functions
high: attempt to represent as close as possible the functionality of the final product, durable enough to be tested by users
Adv and disadv of physical models
ADV: easily understandable, tangible (testing), clear communication between clients and designers, easier to explore and test ideas
DISADV: may not be accurate, time consuming, added cost, environmental impact, materials may not be accurate to those in final product
