Reliable
• 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
1. Kartikey’s Design
Pros(+)
Cons(-)
Simple
Dimensioned well
Used incline plain wrong
No thickness
Requires a lot of input force
Self-loading
2. Courtney’s Design
Pros(+)
Cons(-)
Multi-view and isometric
not dimensioned well
drawings
Follows all size constraints
No bin
Very neat
Lever too complicated and
would not work
3. Sarah’s Design
Pros(+)
Cons(-)
Aluminum can bin is really
tall (all space will be taken
up
Follows all constraints
Very neat
Bin may tip over when
crushing a can
complex
Not self-loading
Uses a lot of material
4. 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
