  1. RHS Tech Ed The Engineering Design Process

  2. What Is Design?

  3. A design process is a systematic problem-solving strategy, with criteria and constraints, used to develop many possible solutions to solve or satisfy human needs or wants and to narrow down the possible solutions to one final choice. – ITEA Standards for Technological Literacy What Is a Design Process?

  4. Design Process used in RHS • Define the Problem • Identifying Criteria and Specifying Constraints • Researching and Generating Ideas • Exploring Possibilities & Selecting an Approach • Designing & Making a Model or Prototype 6. Testing and Evaluating the Design Using Specifications 7. Communicating Processes and Results 8. Refining the Design

  5. 1. Define the Problem • Identify a problem • Break the scenario down to its simplest ideas • Validate the problem • Who says it is a problem? • Needs and wants • Prior solutions • Justify the problem • Is the problem worth solving?

  6. 2. Identifying Criteria and Specifying Constraints • Create design requirements • What do you want to accomplish • Identify materials • Identify tools • Identify what can and cant be done

  7. 3. Researching and Generating Ideas • Research • Brainstorm possible solutions • Consider additional design goals • Apply STEM principles • Select an approach

  8. 4. Exploring Possibilities & Selecting an Approach • List all ideas gathered • Take each possibility and expand • Evaluate plausibility • Determine which idea is the best

  9. 5. Designing & Making a Model or Prototype • Create detailed design solution • Justify the solution path • Technical Drawings

  10. 6. Testing and Evaluating the Design Using Specifications • Construct a testable prototype • Plan prototype testing • Performance • Usability • Durability • Test prototype • collect test data • analyze test data

  11. 7. Communicating Processes and Results • Document the project • Project Portfolio • Communicate the project • Formal Presentation

  12. 8. Refining the Design • Evaluate solution effectiveness • Reflect on design • Recommend improvements • Optimize/Redesign the solution • [Return to prior design process steps, if necessary] • Revise design documents
