  1. Emergency Release Snowboard Bindings Presenting: Michael Allen Michael Weidner David Call University of Utah Department of Mechanical Engineering

  2. Introduction • Schedule • Budget • Team Groups • Focus Of The Different Groups • Final Design

  3. Schedule Emergency Release Snowboard Binding Year Schedule Source: ERSB Final Report Fall ‘06

  4. Budget Budget of Emergency Release Snowboard Binding Team Source: ERSB Final Report Fall ‘06

  5. Group Division • Why • Based on schedule and interest • Ensure each area is complete • Make sure everyone is busy and is communicating with others about progress

  6. Group Division • Groups • Finalizing Design • David Call, Michael Weidner • Manufacturing and Analysis • Michael Allen, Jason Wendel • Remote Control • Blake Anderson, Gavin Mehraban, Matthew Sartori

  7. Current Work • Design Team • Manufacturing and Analysis Team • Remote Team

  8. Current Work • Design Team • How to make design universal • No large forces on small parts • Strength Analysis

  9. Current Work • Manufacturing and Analysis Team • Material Selection • Manufacture of top plate • Calculate expected forces of snowboarding

  10. Current Work • Remote Team • Benchmarking remote switches • Researching design with lithium batteries

  11. Final Concept • What it is • How it works • Interface with board and binding • Attach • Emergency Release • Why we chose it

  12. Concept - Background • Concept replaces disk • Holds binding to board • Used in all setups Snowboard Setup Binding Disk Snowboard Photo: David Call

  13. Concept Current Disk ERSB Disk Concept (Exploded) Top Plate Lock Fins (4) Rotating Disk Latch Bottom Plate Snowboard Photo and sketch: David Call

  14. Securing the Binding • Rotating disk extends/ retracts fins • Fins hold down top plate • Top plate holds binding to board Top Plate Cross-Section Internal Ledge Against Binding Binding Lock Fins Disk Ledge Extended Retracted Photo and sketches: David Call

  15. Releasing the Binding Release Mechanism • Shape Memory Alloy (SMA) wire contracts at 70° C • Lithium battery provides current • Remote Control Activated Shape Memory Alloy Wire Spring Load (White) Latch Rotating Disk Image: David Call

  16. Concept Evolution Various concepts • Combined best features from 50+ concepts • Best serves customer needs Sketches: (Clockwise from top) Matthew Sartori, Michael Allen, David Call, Jason Wendel

  17. Additional Appeal • Ambitious • All moving parts contained (away from elements) • What members of group would want to buy

  18. ERSB • Schedule and budget • Split our team into groups • Current work • Final design
