Objetives
• Students will learn to build appearance models using different materials: foam, plastic filler, plaster, resin, silicone, and so on.
• Students will learn the function of ergonomic, appearance and functional models, and the difference between them and their importance in the design process.
• Students will learn to use machines to build prototypes in wood.
What is an appearancemodel?• An appearance model is the one that shows the
physical, volumetric and ergonomic characteristics of a product.
• It is as similar as possible to the design proposal.• It can show some function.• It is used to evaluate characteristics of
ergonomics, customer perception and appreciation, study of color and form, conceptualization (focus group).
3D Sketching and conceptual model3D Sketching: Materialization of ideas through the quick manipulation of materials such as plasticine and cardboard.
Conceptual model: They represent the first design proposals
Ergonomic models
Models made with rigid materialsto assess ergonomic aspects: handgrip, visual weight, locations, textures, etc.
Ergonomic model evaluation
Handgrip, shape, inclinations, weight, balance, positions, reach, textures, etc..
Focus group
Conceptual model Ergonomic model Appearance model
Appearance model processes
Molds and casting
Sanding and polishing resin
Cutting and grindinghigh density foam
Assembly and adjust resin in foam
Appareance models
Appareance models
Thermoforming
• Thermoforming plastic is used to generate covers commonly used in packaging (blisters).
• Plastic take the form of an external volume and gives value to generate models of products and parts for models.
Thermoforming examples
Thermoforming process in PETG: cutting, taping and painting.
Prototypes
A prototype is:
- Functional.- Use equal materials of original proposal.- It looks like the original product.
- Allows us to check performance, aesthetics, dimensions, ergonomics, production feasibility, market acceptance (focus group).
- You can work on it to generate modifications.
Picture frames
of wood
Prototype built in wood project, where you learn to use basic cutting machines to produce more complex prototypes.
