By this Design Review Checkpoint, we hope to complete a few goals that will bring us closer to the final product. ​

• CAD model of iPhone 6 plus case

  • Design CAD model for a bumper case design that can be printed

  • Print out at least one copy of CAD model in Type A printer with a material of our choosing.

• Obtain dummy model of iPhone 6 Plus to use in testing

  • Check for fit of printed case on iPhone 6 Plus dummy model

  • Mark places of good/bad fit on case model

• Create preliminary drop test modeling

  • Calculate terminal velocity and force of impact as a function of drop height

  • Video track iPhone drop test on concrete in order to create position, velocity, acceleration, and jerk vs time graphs.

  • Use graphs to compare difference between with and without case drop tests.

• Stated goal: Materials and process selection for up to three key components of your mechanism. Carry out your material/process selection with full-scale manufacturing in mind rather than prototyping.
