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

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

Ethical Issues

• Socially Responsible

• Promote Recycling

• Safe

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.
