1. Engineering Design Process Brookville Intermediate School 7 th Grade

3. Step 1: Identify the Problem Specify and prioritize requirements and limitations to better define the need or problem. Design requirements state the important characteristics that your solution must meet to be successful. The requirements or criteria are often given to the engineers by the client and often include limitations.

4. Step 2: Research the Need or Problem Identify questions to ask about your target user or customer. Identify questions to ask about the products that already exist to solve the problem you defined or a problem that is very similar.

5. Step 3: Develop Possible Solutions DON'T SETTLE FOR YOUR FIRST IDEA! Try to generate as many possible solutions as you can before choosing one that you feel is the best. This creative process of developing ideas is called ideation. Methods of ideation include: – Examining existing solutions – Conducting brainstorming sessions – Sketching and doodling

6. Step 4: Select a Solution Look at whether each possible solution meets your design requirements. Consider solutions that did a much better job than others, and reject those that did not meet the requirements.

7. Step 5: Construct a Prototype A prototype is a working model of a solution. It is often made with different materials (cheaper and easier to work with) than the final version. Prototypes allow you to test how your solution will work and even show the solution to users for feedback. Prototypes help you to create your solution quickly and with little cost. Keep in mind that these are mockups of your final solution, not the real thing!

8. Step 6: Test & Evaluate Your Prototype Test your final design with your users. Does it meet the original requirements and limitations?

9. Step 7: Communicate Results To complete your project, communicate your results to others in a final report and/or a display board. Professional engineers always do the same, thoroughly documenting their solutions so that they can be manufactured and supported.

10. Step 8: Redesign Based on your test results and user feedback, redesign your solution to make it better. Repeat this process of testing, determining issues, fixing the issues, and then retesting multiple times until your solution is as successful as possible. Make sure to document all your testing and redesign. Record your data from your test results and your sketches or schematics of each redesign.

12. Your company, Lockheed Martin, has just been awarded a contract to build a HIGH speed propeller aircraft. Before you can design what the aircraft looks like you must first figure how to create a propeller aircraft that is the quickest with the materials provided. Lockheed Martin is willing to award the winning engineering team who stays within the time deadline a bonus.
