Customer Requirements and Product Selection ■ Target Audience: Children from ages 6-14 ■ We wanted to choose a product that involved physics, but was also intriguing to children. – Interactive and visual components – Possibly involve some humor
Conceptual Design ■ Main components: Windmill, Gears, Spinning Platform, Mass on String ■ User will blow on windmill, which will initiate spinning of gears. The gears will rotate a platform, which will cause a mass on the string to rotate around the rod.
Actual Design ■ Changes: – Replaced windmill with a four- pronged handle the user can turn – Two spinning masses instead of one – Smaller spinning platform ■ Main platform was constructed from wood and glue and then painted black ■ Gears were 3D printed in various colors

Customer Feedback and Results Customer #1 Customer #2 (6 years old) (10 years old) ■ Liked how the design was open ■ Also liked the open design – Could see how the gears were ■ Liked that the gears were different working by rotating each other colors to make the masses spin ■ Liked how the masses were stick around the pole figures
Cost and Time Estimates ■ Design Time: 17 hours ■ Material Cost for 1,000 Units: $5,500.00 ■ Prototype Cost: $5.50 ■ Retail Price for 1 Unit: $9.99 – $3.00 for wood products – $2.50 for 3D printing
Conclusions ■ The user turns a handle which initiates a series of gears to start turning. The final gear rotates with a rod attached to it. Hanging from the top of the rod are two stick figures, which rotate with the spinning gears. ■ Actual design differed slightly from the conceptual design. ■ Cost is $5.50 per unit with a retail price of $9.99 ■ Positive feedback from customers
