About Eng. Design Teams

• Consist of Members with a Mix of Backgrounds and
  Training
• Scientists Have strong training in math and
  science which emphasizes the theoretical.
  Scientists ask "Why?" questions.

About Eng. Design Teams

• Engineers Attempt to do something useful with
  scientific theories and principles, called
  design, i.e., a creative process that produces in
  a new device, system, structure, or process that
  satisfies a specific need.
• Technologists Do much of the actual
  implementation of the engineering designs, like
  CAD drawings, testing, data taking and reduction,
  and directing craftspeople during fabrication.
• Craftspeople Are the practical or implementation
  end of the spectrum. They primarily manufacture
  or assemble the products designed by the rest of
  the team, e.g., welders, machinists, etc.

Developing Models and Prototypes

• All modeling can be broken down into one of two
  categories
• Descriptive Models Depict ideas, products, and
  processes in a way that is recognizable. The
  goal is to show what a design would look like if
  it were created.
• Examples Engineering drawings, 3D computer
  models, or scale models
• Predictive Models Used to test and understand
  how designs ideas, products, and processes will
  perform. May bear little or no resemblance to
  the overall design.
• Examples Mathematical equations or graphs
  showing a relationship between design requirements

23
Developing Models and Prototypes

• Scale models are one of the most basic and
  generally useful because they are very much
  hands-on and provide a good feel for a design and
  its features
• Computer simulation and animation are two other
  common model types
