Engineering Innovation Examples
Above Save the Astronauts (Eggs). Device needed
to rescue without killing the astronauts. It
landed on one table astronauts were on other
table. Device could only be powered by potential
energy started with the cutting of a string.
Extra points gained from lighting LEDs using
magnetic sensors.
Right Chain Reaction Design Challenge. 4
sub-groups design a separate component which is
started by the previous one and ends by starting
the next. Must have action a common theme.

Mechanical Engineering Design Examples
Mrs. Smiths Apple Pie Helper Using an Apple
Slicer Design a machine to slice the apple,
remove the core transport apple slices 1 foot
away into a dish for apple pie. Can only use
rotary mechanical motion to power the device.
Skeeball Competition Design a machine, powered
by a cordless screwdriver to throw/launch plastic
air-filled balls at a target 6 feet away. Pts
for accuracy quantity.
