Problem StatementRoadrunner Trucking wants

us to build a can crusher

that will reduce the volume

of their aluminum cans.

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

ScopeOutputs• Can Crusher• Tech Report• Power PointResources• Internet • Mr. Pritchard- Tech• Miss Hernacki- Math Calculations• Mr. Hund- CAD Drawings

ScopePotential Materials• Wood • PVC• Metal brackets• Metal hinges• Nails and screws

ScopeKey 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 • MaterialsWood, metal hinges, screws and nails

• Size of wood½”-2” thick

• Type of can crusherSelf-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(-)Simple Used incline plain wrong

Dimensioned well No thicknessSelf-loading Requires a lot of input force

Explore Possibilities – Designs 2. Courtney’s Design

Pros(+) Cons(-)Multi-view and isometric

drawingsnot dimensioned well

Follows all size constraints No binVery neat Lever too complicated and

would not work

Explore Possibilities - Designs3. 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 constraints complexVery neat Not self-loading

Uses a lot of material

Explore Possibilities - Designs4. Jon Ko’s Design

Pros(+) Cons(-)Detailed Confusing

Good dimensions Materials used are expensive

Followed most constraints Aluminum can bin does not slide in and out

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

Develop a Design Proposal – Test PlanTest Criteria How Tested Expected results Actual 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

• Test Plan

Test Criteria How Tested Expected results Actual 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

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
