Unit 3 - Modelling Flashcards
Graphical Models
2D drawings, diagrams, and sketches.
Physical Models
3D, clay, cardboard, rapid prototype (other materials)
Advantages of concept models
Allows clients to provide input, reduction of development costs, communicate function and aesthetics
Disadvantages of concept models
Simple concepts (not detailed), materials are not accurately represented, scaled models do not communicate proportions
2D
Quick representations and communications of an idea.
Orthographic Drawing
accurate representation of form, communicates dimensions/form, shows side of a product
Isometric Drawings
no vanishing points, 30/90/60, overall form of a product
Part and Assembly drawings
Shown as an exploded isometric drawing, purpose is to communicate the sequence of assembling a project.
perspective drawings
showing an object as if viewed from a single point.
Sketching
quick to create, easy to communicate
Scale Models
model that is either a smaller or larger physical copy of an object.
Aesthetic models
developed to look and feel like the real product. Form over function
Mock-ups
scale or full-size representation of a product used to gain feedback from users. Some functionality
Prototypes
sample or model built to test a concept or process, or to act as an object to be replicated or learned from. High, mid, or low fidelity.
Low Fidelity
not tangible or durable, but they do communicate basic information about form, shape, function,
Mid fidelity
communicate more about an idea or concept. Have some function
high fidelity
represent as close as possible the functionality of the final product.Durable enough to test and gather usability data.
instrumented models
equipped with the ability to take measurements to provide accurate quantitative feedback
Surface Modelling
only communicates information about the surface of the design.Communicates aesthetics
Motion capture
recording of actual human movement using video, magnetic, or electro-mechanical devices.
Top-down strategies
New features and parts are added as the design evolves. Related parts are connected.
Bottom-up strategies
Individual parts are design separately and then assembled to final design.
Digital Humans
simulations of the biomechanics of the human body
Data models
database or data set that is used to present and or understand the performance fo a design
FEA
Finite Element Analysis: calculation of loads and stresses on a product using CAD software
Solid Modelling
accurate digital models of the whole part or object. Communicates details about dimensions, materials, function, and components.
Virtual Prototyping
allow the designer to simulate the design, communicate with clients and the design team, and explore the design
Virtual Reality
virtual environment where the user can interact with it in a realistic way
FDM
Fused deposition modelling: material is extruded through a model. (Plastics, clays, dough)
Haptic Tech
use the sense of touch to provide feedback to the user.
Animation
used to confirm the placement of equipment and determine safety, ergonomics, and efficiency of a factory layout.
SLA
Stereolithography: liquid polymerized in a liquid container. (resins)
SLS
Selective Laser Sintering: Metal powder sintered using a laser. (Metal powders, ceramic powders, polymer pwders)
