  1. Design Process • The design process is a method of planning practical solutions to problems. • The design process is never final; there are always multiple solutions to a problem. • The design process is influenced by requirements called criteria and constraints.

  2. The Design Process Define the Problem Investigation Testing & Evaluating Develop Alternative Solutions Choose the Best Solution Models or Prototypes

  3. Define the Problem Defining the problem is like conducting detective work. You must examine the evidence and form some conclusions. Example: Design a vehicle that can communicate with other vehicles to prevent accidents.

  4. Investigation Researchinginformation that you need to help design your product. • Examples: • Read books and magazines • View films or videos • Search the Internet • Ask questions of the “experts”

  5. Develop Alternative Solutions Develop multiple ideas that will solve the problem and meet the requirements. • Criteria: • How will the solution actually work? • What materials should I use? • What should the product look like? • Constraints: • What size should it be?

  6. Choose the Best Solution Decide on an idea that best meets the criteria and constraints. Draft the final design plan. List the strengths and weaknesses of each alternative. Make improvements to the design idea. Trade-off – Giving up one desirable trait for another

  7. Models and Prototypes Construct the solution! • Prototypes - first version of a solution • Models- actual size or to scale Examples: Models are small, accurate representations of the final product. A prototype is a working model; it looks and functions just like the finished product 3D CAD (computer aided designs) can show objects in action.

  8. Testing and Evaluating Does it work? Does it solve the problem? Will modifications improve the solution?
