5. Timeline Kept us on task

6. Problem Statement

7. Background Roadrunner Trucking → a lot of aluminum cans Aluminum cans must be reduced by 70% $0.05 fine per can

8. Customers Mr. Pritchard -ITC instructor Roadrunner Trucking -company we give product to

9. Scope Outputs Can Crusher Tech Report Power Point Resources Internet Mr. Pritchard- Tech Miss Hernacki- Math Calculations Mr. Hund- CAD Drawings

10. Scope Potential Materials Wood PVC Metal brackets Metal hinges Nails and screws

11. Scope Key Constraints Max space of 18”×24”×30” One simple machine One unit Manually operated Bin must hold 20 uncrushed cans

12. Deliverables Can Crusher Tech Report Power Point presentation

13. Brainstorming Materials Size Type of can crusher

14. Research and Generate Ideas Materials  Wood, metal hinges, screws and nails Size of wood  ½”-2” thick Type of can crusher  Self-loading with lever

15. Criteria Self-loading Inexpensive Simple Not time consuming Reliable

16. Constraints Max of 18” x 24” x 30” Materials: wood, PVC, metal brackets, metal hinges, screw & nails One simple machine Crushed can falls into aluminum can bin Bin slides in and out of crusher Bin holds 20 uncrushed cans

17. Explore Possibilities – Designs 1. Kartikey’s Design Pros(+)Cons(-) SimpleUsed incline plain wrong Dimensioned wellNo thickness Self-loading Requires a lot of input force

18. Explore Possibilities – Designs 2. Courtney’s Design Pros(+)Cons(-) Multi-view and isometric drawings not dimensioned well Follows all size constraintsNo bin Very neatLever too complicated and would not work

19. Explore Possibilities - Designs 3. Sarah’s Design Pros(+)Cons(-) Aluminum can bin is really tall (all space will be taken up Bin may tip over when crushing a can Follows all constraintscomplex Very neatNot self-loading Uses a lot of material

20. Explore Possibilities - Designs 4. Jon Ko’s Design Pros(+)Cons(-) DetailedConfusing Good dimensionsMaterials used are expensive Followed most constraintsAluminum can bin does not slide in and out

27. Develop a Design Proposal Build Process  Obtain material  Trace outline of piece  Cut the material  Sand it  Glue, nail, or screw pieces  Assemble

28. Develop a Design Proposal – Test Plan Test CriteriaHow TestedExpected resultsActual Results Reliability Crush a can, measuring size before and after crushed The can will be crushed to 70% of its original height Durability Crush a can, open and close the drawer of the bin that stores aluminum cans The aluminum can bin will slide in and out with ease Bin Must Hold 20 Crushed Cans Put 20 cans crushed in the bin All 20 cans will be crushed Self- Loading Put 3 cans into the self- loading mechanism and crush all three cans The crusher will be able to self- load appropriately without any complications Can Must End-up In Bin After Being Crushed Crush a can and see if it falls through the appropriate hole into the bin The can will fall through the hole into the bin

29. Prototype

30. Test and Monitor Test Plan Test CriteriaHow TestedExpected resultsActual Results Reliability Crush a can, measuring size before and after crushed The can will be crushed to 70% of its original height The can was crushed to 1.5” Durability Crush a can, open and close the drawer of the bin that stores aluminum cans The aluminum can bin will slide in and out with ease The aluminum can bin slid in and out with ease Bin Must Hold 20 Crushed Cans Put 20 cans crushed in the bin All 20 cans will be crushed Bin could hold 20 cans Self- Loading Put 3 cans into the self- loading mechanism and crush all three cans The crusher will be able to self- load appropriately without any complications The self- loading mechanism held 3 cans Can Must End-up In Bin After Being Crushed Crush a can and see if it falls through the appropriate hole into the bin The can will fall through the hole into the bin The can fell into the bin with ease

31. Refine Re-made lever pieces due to hex bolts Took out handle Made outside bin hole bigger Changed CAD drawings

32. Lessons Learned Complete tasks without re-doing them Assign work evenly Use hand and power tools

33. Summary Learned a lot about can crushers Procrastination Work as a team Stay positive Make decisions together
