ENGINEERING FOR A NEW ECONOMY
Product engineers develop new products and design process for how these products will be manufactured. You are a product engineer for a big, new toy company on your Star Wars planet. Your job is to develop new toys and to design a process for how these toys will be manufactured.
Your company has asked you to develop the next, “must have” electronic toy. You have noticed that kids all over the galaxy idolize the New Jedi Order.
You hear kids talking about how they want to be a Jedi one day and it gives you an idea.... Light up toy lightsabers!
The toy lightsabers you see in stores work using an electric circuit, LED light, and switch. Watch the video below to see how circuits, lights, and switches work.
You have been given a materials bag. Make sure you keep all your materials in your taped off section of the table. The bag should contain:
Keeping in mind all you learned about circuits in the previous video, you will construct the light up lightsaber prototype. Use the video tutorial below to help you if you get stuck.
All professionals reflect at the end of a project. They think about several things when they reflect. They ask themselves questions to make sure they met the requirements of their task, job, or project. Then, they identify the problems or issues, brainstorm improvements, implement those improvements, and test those improvements.
CHECK YOUR UNDERSTANDING
EVALUATE WHETHER THE PROTOTYPE MEETS THE REQUIREMENTS
- Think back to the credits and scenario. How do you know kids all over the galaxy will want your product?
- Profits are the money that is made on a product after you subtract what it cost to make the product. Why do you think this toy will have high profits? (Hint: think about the materials you used and how difficult it was to make it.)
INNOVATIONS TO BUILDING AND MANUFACTURING YOUR PROTOTYPE
- What problems or issues did you experience as you were building your prototype? How might you change the building process to solve the problem or avoid the issue?
- Does your prototype have any problems or issues? How could you fix these problems or issues?
- How could you improve your prototype? What resources would you need to make this improvement? How would it impact the profits you make?
