  1. Backpacking Pain Points ● Sore shoulders ● Unreliable energy sources

  2. 12.2 million backpackers in US

  3. Our Solution Linear Bearings “Floating” Pack Spring/Damper System Charging Battery

  4. Can we reduce peak forces felt by a backpacker?

  12. Springs Worsened Forces!

  13. Results Explained - Model is overly simplified - External damping force needed

  14. Next Steps - Reassess feasibility with different suspension models - Pulley system - Dampers - Select electricity generation method - Magnetic flux induced current - Linear to rotational motion
