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
