EXPLORE CONTINUED These cases were too soft Didn’t protect the headphone jack Charging slot was open Couldn’t be taken off easily Isn’t “cool” or has unique colors Too bulky Easily attracts dust and particles

Costs too much $$$

IDEATE

IDEATE CONTINUED First design ideas

Those cases would end up being too bulky and too complex

Couldn’t be painted or able to change colorsWeren’t easy to take on and offMaterials and manufacturing costs would be

too highDidn’t fully fit what Nick wanted

PROTOTYPE/ REFINE

SOLUTION My final design ended up being at a cost

of ~$10.00 It covered the headphone jack, charging

port, buttons and camera I choose TPU as a material for the case

Thermoplastic polyurethane has extremely good characteristics for a case (high elasticity, oil and grease resistance, shear strength and abrasion resistance)

It is also very affordable It is made in molds so manufacturing costs

are very low
