Project Background

1. Project Background • B9 Plastic’s Better Water Maker strives to provide clean, disinfected water to over 800 million people worldwide. • The current system treats ½ gallon of water per minute by the use of a manual hand crank to provide power to the pump and UV light. • The water passes by the UV light where it is sanitized. • Previous Projects • One design utilized a hand crank flywheel as a method of power generation. • Second design improved upon the first and used a recumbent foot petal instead of the hand crank. • Third design focused on removing the turbidity of the water by the use of a French press style of filter. • Previous iterations of the projected were regarded as good ideas but were not executed.

2. Problem Statement • The goal of this project is to create a cheaper system that requires less effort to operate and is fun for women and children to use. • Cost of the system must be reduced to $100/unit for 1000 units. • The components of the UV system must not altered. • Lamp must be powered on for 10 seconds • Gap between UV light and water • Type of bulb • The complete system should be mobile and lightweight to allow for easy storage. • Fully functioning prototype must be completed by the end of MSD II.

3. Project Objectives • Run “some amount” of <5 turbidity water through the UV system to sanitize it to “certain level”. • Redesigned mechanical power generation system. • Reduced cost from $200/unit to $100/unit. • System is easy and fun to use.

4. Deliverables • Completed BWM that meets the needs of the users and B9 Plastics • Bill of materials • Design drawings for manufacturing or modifying by users • Assembly plan • User manual for low literacy users • Test plan and documented results

5. Expected Project Benefits • Allow users in developing countries access to disease-free water. • Improve RIT’s reputation in environmental sustainability.

6. Team • Anna Sementilli (Industrial Engineer, Team Leader) • Maxamillion McMahon (Mechanical Engineer) • Tyler Schmidt (Mechanical Engineer) • Tyler Burns (Mechanical Engineer) • Nicolas Reginelli (Electrical Engineer) • Jason Andrews (Electrical Engineer)

7. Assumptions & Constraints • UV disinfection system treats ½ gallon of water per minute • Manual power generation must generate at least 17 watts of power • Total system cost must be less than or equal to $100/unit for 1000 units • UV lamp needs 10 second lead time • Must use off the shelf parts • Cannot alter UV disinfection system

8. Issues & Risks • Project Risks • Keeping unit cost under $100 • Not finishing before ImagineRIT or at all • New topics that team is not familiar with • Technical Risks • Product is not safe to use • Failure modes not accounted for before production • Users have no interest in product (not fun to use) • Lifetime of product not to desired length

22. Team Norms • Meetings • Everybody contributes • 12 hour advance notice of missing meeting makes it ‘excused’ • Re-evaluate meeting time after 2 ‘unexcused’ misses • Let the team know if you can’t make a deadline before its too late • Work/Responsibilities • Common work to be divided • Specialized work distributed by expertise and strengths • Somebody will check work • Communication • GroupmeText Messaging • Email • Meeting

23. Team Roles and Responsibilities • Anna – Team Leader • Jason – Communications • Roles determined by expertise as needed Problem Resolution • Discuss face to face to determine why the expectation is not being met • Team Leader will facilitate the conversation • Consult with Gary if it becomes a regular issue
