4. Project Background ●2012 - 261 diagnosed concussions ●2013 - 228 diagnosed concussions ●With 256 regular season games ●On august 29th, 2013 a lawsuit was taken against the NFL for a total of 765 million dollars. ●Manufacturers Include: Riddell, Schutt, Adams, and Xenith ●http://www.cnn.com/2013/08/30/us/nfl-concussions-fast-facts/http://www.cnn.com/2013/08/30/us/nfl-concussions-fast-facts/

5. Problem Statement Current State: ●Limited to manufactured helmets in contact sports Desired State: ●Custom Fit helmets using 3D printed Thermoplastic Urethane (TPU) as the padding to absorb energy from the impact Project Constraints: ●Overall helmet weight benchmarked against competitors ●Durability ●Manufacturability ●Biocompatability ●$1000 budget Key Goals and Deliverables...

12. House of Quality Key: ⊝ - strong correlation o- moderate correlation ▲- weak correlation

13. Benchmarking

14. Risks and Concerns ●Will TPU really be the best “foam” option for preventing concussions impacts? ●Cell wall stiffness will affect density calculations and segment size. ●Time requirement to scan, import, and print must be short to make idea practical. ●Will the testing and design phase require more material than expected? ●How will 3-D printed foam help reduce concussions from rotational impacts?
