  1. Prepared by: Jeanelle Baldric Matt Borkowski Doug MacNerlandJacob Sellers Can Crusher Project

  2. AGENDA • Group development • Research and generating ideas • Developing our design • Designing our prototype • Building our prototype • Design revisions • Lessons learned

  3. THE TEAM • Leader: Doug MacNerland • Scribes: Matt Borkowski & Jacob Sellers • Timekeeper: Jeanelle Baldric

  4. CONSTITUTION • Respect each other and the project • Work hard • Listen to one another • Encourage, not discourage • Stay on track • Spend time outside of class and in study hall • Ask for help if needed • Never give up

  5. TIMELINE

  6. TIMELINE

  7. THE PROBLEM • Problem statement: We work for Alpha Engineering Company. Roadrunner Trucking, a customer of our company, has received a notice indicating that the total volume of the aluminum cans the company disposes must be crushed to a minimum of 1.5” (or 30% of its original size).

  8. BACKGROUND & JUSTIFICATION • The can needs to be crushed 30% of its original size • 18” x 24” x 30” • Usable materials: Wood, pvc, metal brackets, metal hinges, screws and nails. • 5% bonus if self-loading • Bin must hold at least20 crushed cans • Manually operated

  9. CUSTOMER • One customer • Mr. Pritchard – ITC instructor

  10. SCOPE • Task: Design a can crusher • Main source: Internet • Subject Material: • Calculations – Hernacki • Building & Testing – Pritchard • CAD Drawings – Hund

  11. DELIVERABLES • Can Crusher • Technical Report • Powerpoint Presentation

  12. BRAINSTORMING • Who came up with the can crusher? • When was the original can crusher made? • What kind of wood is best used for building? • How big is the average soda can? • How much force is needed to crush a can to 30% of its original size? • Safety hazards

  13. RESEARCH & GENERATE IDEAS • Can Crusher: device used for crushing soda cans for easy storage in recycling bins • Original can crusher made by Jesse Wright • 100-200 lbs needed to crush a can • Wood types • Wood glue and screw strength • Crushing methods

  14. CRITERIA AND CONSTRAINTS • Crushed to 30% of original size • Max dimensions of 18”x24”x30” • Minimum of one simple machine • Allowed to put can in the crusher (5% bonus for self-loading system) • Crushed can must fall in the bin automatically • Bin holds at least 20 crushed cans • The bin must come in and out of the crusher • All parts must be fabricated

  15. EXPLORE POSSIBILITIES • Four designs • Jacob’s • Jeanelle’s • Matt’s • Doug’s • Evaluated different materials

  16. JACOB’S DESIGN

  17. JACOB’S DESIGN (CONT.) • Pros • Well dimensioned • Sliding bin • Isometric sketches • Cons • No simple machine • Difficult to crush can

  18. JEANELLE’S DESIGN

  19. JEANELLE’S DESIGN (CONT.) • Pros • Semi-dimensioned • Many simple machines • Cons • Very complex • Difficult to make

  20. MATT’S DESIGN • Pros • Self-loading • Simple machine • Cons • Little dimensions • Hard to crush the can

  21. DOUG’S DESIGN

  22. DOUG’S DESIGN • Pros • Simple machine • Easily crushes • Cons • Little dimensioning • No obvious bin • Sloppy

  23. WOOD TYPE (Ranked 1-5 with 5 being the best)

  24. BUILDING WITH... (Ranked 1-5 with 5 being the best)

  25. SELECT AN DESIGN (Ranked 1-5 with 5 being the best)

  26. DESIGN PROPOSAL • CAD drawings • Bill of materials • Build process • Test plan

  27. PROTOTYPE • Large sloped bin • Crushes vertically • Little support • Self-loading

  28. BILL OF MATERIALS

  29. BUILD PROCESS • Bin • Obtain plywood • Draw out necessary parts (8 x2, 9, 10) • Cut along lines with band saw/ circular saw • Sand down parts if necessary • Assemble using screws and wood glue in appropriate places

  30. BUILD PROCESS (CONT.) • Crushing Mechanism • Draw out parts 11 x2, 12 x4, 13, 14 x2, 15 x2, 16, 17 • Cut along line with band saw/ circular saw • Drill holes with drill press in appropriate places • Sand if necessary • Assemble using screws and wood glue as according to the CAD assembly

  31. BUILD PROCESS (CONT.) • Can Crusher • Draw out parts 1-6 as according to the CAD drawings • Cut out with band saw/ circular saw • Sand if necessary • Assemble with screws and wood glue as according to the CAD assembly

  32. BUILD PROCESS (CONT.) • Can Crusher and Crusher Mechanism • As according to the CAD assembly, make sure they fit together • Sand if necessary • Attach with both screws and wood glue • Put two nails in the slits in parts 2 and 6

  33. TEST PLAN

  34. PROTOTYPE • Build process kept us organized • 2 weeks worth of build time • Many errors during building • Design was unstable • Many minor cutting errors

  35. TEST AND MONITOR • Entire design fell apart • Major issues to the design

  36. REFINING THE DESIGN • Made an entire new design • Wider than original • Bigger bin • Better crushing design • Much more stable

  37. REFINED DESIGN • Crushed easily • Large bin • Self-loading • Very stable

  38. TEST AND MONITOR #2 • Major issues fixed • Problems gone • Easy to crush

  39. LESSONS LEARNED • Jacob • Trust in group members/self • Keep it simple • Time management • Jeanelle

  40. LESSONS LEARNED (CONT.) • Matt • Doug

  41. SUMMARY • Worked well as a group • Worked well under stress • Overall enjoyable experience
