  8. Problem statement • The group must fabricate a can crusher for Roadrunner Trucking that will reduce the volume of each aluminum can by 70% using at least one simple machine.

  9. Background • Soda cans too large to dispose • Reduce can size by 70% • Use at least 1 simple machine • Bin to hold 20 cans • Finished by May 18th, 2012

  10. Customers • Roadrunner Trucking: • Needs to reduce cans by 70% • If not $0.05 penalty fee. • Mr. Pritchard: • ITC teacher • Collects Deliverables

  11. Scope

  12. Deliverables

  13. Brainstorm

  14. Research • 100-170 lbs. of force • Simple machines decrease effort • Attach: • Wood glue, screws, nails, dowels • Crushed Can= 1.5” x 2.5”= App. 18in^3 • Soft wood used because it’s cheaper.

  15. Criteria • Minimum of one simple machine • Must fit within 18x24x30 box • PVC, Wood, Metal Hinges, and Brackets • Can must drop into bin • Bin must hold 20 crushed cans

  16. Constraints • Must follow PLTW Design Process • No human intervention when dropping can • Bin must slide out of the crusher • All parts must be fabricated • Must be manually operated • Must be one unit • Cannot have pre-dented cans • Only one operator • Bin must hold 20 crushed cans

  21. Scale: 1-10 1 being lowest, 10 being highest Select an approach

  22. Select an approach Scale: 1-5, 1 being lowest, 5 being highest.

  23. Select an approach Scale: 1-5, 1 being lowest, 5 being highest.

  24. Bill of materials • *Group Member already had

  25. Test plan

  26. Work process • Cutting: • Lay out work on wood boards. • Cut by sections. • Cut each piece out. • Assembling: • Preassemble all pieces • Sand pieces to ensure squareness. • Screw together/ or glue together. • Check again for squareness.

  27. Let’s Go to work

  28. Prototype • Used time effectively from the start • Closely followed build process • 2 refinements to build process • Labeled parts by CAD plate • Painted the crusher • Refinements to crusher • Lever handle instead of wheel • No self loader

  29. Test and evaluate

  30. Refinements • Simple machine component • Initially wheel and axle • Now lever and wheel and axle • Spray painted crusher • Got rid of automatic loader

  31. Lessons learned • New Tools • Effective teamwork makes it easier • Don’t rush • Not procrastinating is less stressful

  32. Summary • Team development • Timeline • PLTW 12 step • Steps 1-10 • Lessons learned
