Transcript of Soap Dispenser Presentation

With consumers all around the country spending 2.32 billion dollars on soap every year (Daily Finance), it is important that consumers are getting their money’s worth. Modern soap dispensers are incapable of extracting all of the soap in the container, making 2 million pounds of soap wasted each year (CNN).
Final Design
When choosing a problem we looked at a series of different topics and decided there were multiple problems with soap dispensers.
Brainstorming and Preliminary Sketches
Justification
Testing and Results
Problem Statement
Selecting a Design
Re-Designed Soap Dispenser
Almost everyone uses soap and so there is a very big market for a improved dispenser.
Millions of pounds of soap are being wasted which translates into much money lost
Off the shelf soap dispensers waste 10-20 milliliters of soap on average.
Selecting a Problem
Statement of Purpose
Develop a solution to the design failure of pump soap dispensers so that they are not wasteful of the product.

Preliminary Design
Prototyping
Conclusion
The redesigned soap dispenser saved an average of 36.6 mL of soap.

Annually, 220.4 million dollars worth of soap would be saved with the redesigned soap dispenser.
Previous Designs
Testing Protocol
The soap dispenser was originally filled with 30 mL of soap. A graduated cylinder was then positioned at the tip of the common soap dispenser to collect the soap. All of the soap would be pumped out until none more could be extracted. The amount of soap collected is then subtracted from the original 30 mL. The process is repeated three times for each soap dispenser.
Acknowledgments
We would like to thank our instructor Mr. Howardell for his guidance through the whole project, and our project mentor Mr. Tamooka for his suggestions and helpful advice. We would also like to thank Paradise Valley High School, and CREST for their support of the project.
