  1. Lesson 3-2The Design Process Foundations of Technology

  2. Standard 5 • Apply the Design Process

  3. Clear Target • Students will be able to understand and apply the design process to solve a problem, given available materials and constraints.

  4. Problem Solving • Engineers use the Engineering Design Process to solve problems. • There are many different variations, but this is the Design Process that you will learn: • Identify the problem • Explore possible solutions • Design your product • Create your product • Try out your product • Make your product better • Communicate your results

  5. Step 1: Identify the Problem • What is the problem? • What constraints (limits) do you have? • What are the specifications?

  6. Step 2: Explore Possible Solutions • Brainstorm! • Come up with as many solutions as possible • No idea is too crazy • No criticism • Improve on existing ideas • Research to identify and build upon existing ideas. • Quantity is important here • Evaluate each idea and choose the best one

  7. Step 3: Design Your Product • What materials will you use? • How will you manufacture it? • Create working drawings • Determine cost

  8. Step 4: Create Your Product • Build a prototype (working model)

  9. Step 5: Try Out Your Product • Test your prototype • Does it meet your specifications? • Does it do what it should?

  10. Step 6: Make it Better • Can you improve on your existing idea? • Make modifications. • If you made changes, re-test your product. • If you are finished, proceed to next step.

  11. Step 7: Communicate Your Idea • Modify working drawings to reflect the finished product.

  12. Key Points to Remember • Design problems are seldom presented in a clearly defined form. • Your design needs to be continuously checked and critiqued to see if it still suits your needs. • Risk analysis should be used to minimize unwanted side effect. • Can your invention hurt anyone or damage property?
