Pros(+) Cons(-)Simple Used incline plain wrong
Dimensioned well No thicknessSelf-loading Requires a lot of input force
![Page 18: Agenda Group Developments Timeline Problem Statement Background Costumer Scope Deliverables Brainstorming Research & Generate Ideas Criteria Constraints](https://reader037.vdocuments.us/reader037/viewer/2022103122/56649ce05503460f949aa492/html5/thumbnails/18.jpg)
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
![Page 19: Agenda Group Developments Timeline Problem Statement Background Costumer Scope Deliverables Brainstorming Research & Generate Ideas Criteria Constraints](https://reader037.vdocuments.us/reader037/viewer/2022103122/56649ce05503460f949aa492/html5/thumbnails/19.jpg)
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
![Page 20: Agenda Group Developments Timeline Problem Statement Background Costumer Scope Deliverables Brainstorming Research & Generate Ideas Criteria Constraints](https://reader037.vdocuments.us/reader037/viewer/2022103122/56649ce05503460f949aa492/html5/thumbnails/20.jpg)
Explore Possibilities - Designs
4. Jon Ko’s DesignPros(+) 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 – 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
