1. Lesson 3-2 The 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?
