Summary

3. Background Design a can crusher? Developed preliminary concepts
Conducted patent search and market research

4. Patent Search 166 existing patents Six benchmark designs
Mechanical crushing devices
Electro-mechanical devices
Six benchmark designs

5. Findings Several flaws in existing designs
Existing can crusher designs are not marketable
98% of household cans are 12oz. beverage cans

6. 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

Safety Precautions
Reliable

22. Ethical Issues
Socially Responsible
Promote Recycling
Safe

23. 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.
