Background
• Design a can crusher?
• Developed preliminary concepts
• Conducted patent search and market research
Patent Search
• 166 existing patents– Mechanical crushing devices– Electro-mechanical devices
• Six benchmark designs
Findings
• Several flaws in existing designs
• Existing can crusher designs are not marketable
• 98% of household cans are 12oz. beverage cans
Objectives
Develop and construct a can crusher that:
• Is low cost• Is reliable• Is compact• Is aesthetically pleasing• Crushes 12 oz. Aluminum beverage cans to 25%
of original size

Prototype Development
• Purchased Components
• Machined Components
• Designed for Manufacturability
• Designed for Assembly
Product Evaluation
• Prototype met major specifications
• Production version additions
Specification Prototype ProductionCrush 12oz. can 75% Electrically Driven Auto removal of crushed can Mounted on disposal bin Accept can w/ fluid Overload sensing Lid safety switch Aesthetically pleasing
Production Additions
• Disposal Bin• Sealed crushing chamber• Clutch or load sensing• Lid safety switch• Plastic housing• Expandable base
• One button control• V belt• Acme screw • Castings or
Stampings• Latching Lid• Wider can rest
Environmental, Health and Safety
• Minimal Negative Environmental Impact
• Ergonomic Design
• Safety Precautions
• Reliable
Social Implications
• Basis for our Product
• Everyday 120 million cans are land filled, littered or incinerated in the U.S.
• In 2000, recycling rate dropped to 55%
• Recycling cans saves up to 75% of the energy required to produce them from raw materials.
Summary
• Creative Brainstorming
• Research
• Concurrent Engineering
• Prototype Fabrication
• Testing
• Great Project
