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
