Problem Statement
Background Roadrunner Trucking → a lot of aluminum cans Aluminum cans must be reduced by 70% $0.05 fine per can
Customers Mr. Pritchard -ITC instructor Roadrunner Trucking -company we give product to
Scope Outputs Can Crusher Tech Report Power Point Resources Internet Mr. Pritchard- Tech Miss Hernacki- Math Calculations Mr. Hund- CAD Drawings
Scope Potential Materials Wood PVC Metal brackets Metal hinges Nails and screws
Scope Key Constraints Max space of 18”×24”×30” One simple machine One unit Manually operated Bin must hold 20 uncrushed cans
Deliverables Can Crusher Tech Report Power Point presentation
Brainstorming Materials Size Type of can crusher
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
Criteria Self-loading Inexpensive Simple Not time consuming Reliable
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
Explore Possibilities – Designs 1. Kartikey’s Design Pros(+)Cons(-) SimpleUsed incline plain wrong Dimensioned wellNo thickness Self-loading Requires a lot of input force
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
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
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

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

Refine Re-made lever pieces due to hex bolts Took out handle Made outside bin hole bigger Changed CAD drawings
Lessons Learned Complete tasks without re-doing them Assign work evenly Use hand and power tools
Summary Learned a lot about can crushers Procrastination Work as a team Stay positive Make decisions together
