Overall
What is physical modeling? - the essentiall idea
A physical model is a 3D, tangible representation of a design or system.
What is a scale model?
A model that as been shrunk or enlarged at a specific scale.
Meaning?
A model made to look (and sometimes feel) like the final product
Meaning
Full-scale representation of an IDEA of a product.
Meaning
Models used to extract performance data across a range of criteria for verification and validation of a product.
What does physical mean?
Having a material existence. Can be identified using the senses (e.g. Touch, Sight, etc.)
What are the qualities of an aesthetic model?
Does not function
Only concerned with form, style, texture and color (object is TO SCALE)
Primarily used for ergonomic testing
Aesthetic models are usually formed with clay, foam, rubber, plastic, or wood.
Qualities
Used as teaching, demonstration, design evaluation, and marketing
Used for user feedback
Intention is to make a full-sized replica using inexpensive materials to verify a design.
Used for?
Feedback that provides data on both loading and grounding reaction forces.
Critical design decisions & alternatives- the models help the developer to be able to make decisions and seek alternatives based on their prototype.
Continuous assessment of the multi-planar forces.
Product development and reverse engineering.
What is the main difference between the prototype and a mock-up?
Can only be considered a prototype if FUNCTIONABLE
What are the advantages and disadvantages?
✅ADVANTAGES✅
Makes the object easier to view, especially if the real object is very large or small
Engaging presentation
❌DISADVANTAGE❌
Sometimes hard to manipulate to show how it works.
What do they do?
They are used to observe, explain & predict patterns or behaviors.
PREDICTION: Since models may be physical, mathematical, graphs or computer simulations, as the model parameters are changed, the results may change too.
define fidelity WITHOUT USING NOTES
Fidelity refers to the level of detail and functionality included in a prototype, which depends on the stage of progress you are in.
Advantages and disadvantages?
✅ADVANTAGES✅
Gives the client an idea of how the product would look like in a real environment.
Gives product engineers an idea of how feasibility of producing a product.
❌DISADVANTAGE❌
Expensive.
Needs to be handled carefully as they are only “for show” and are not working models, mock-ups, or prototypes.
