Makeup Professionals Need an Effective Makeup Brush Sanitation Device 45 min wasted washing 12+ hrs wasted drying 99 gallons wasted Bacteria on brushes increases risk for skin infections Superior Solution Brand Potential Key Customer Requirements multiple brushes wash, rinse & dry low cost zero brush damage safe Competitive Landscape Competitive market landscape does not include a device that quickly and effectively washes, rinses & dries multiple brushes. Testing and Validation Future Improvement Acknowledgements Image J testing resulted in an average pixel intensity range less than 30. Testing for gage reproducibility and reliability indicates the device has consistent cleaning and drying capabilities . SolidWorks transient heat analysis proves the brushes can be dried safely with zero brush damage. E N V I E collection Research & Development Drying Conclusion: Hot air was able to remove more water mass from the brush than cool air. Design Integration: Drying cycle includes a fan and heater.

Break Even Point Projected Revenue Unit Cost Sales Price $110.87 $400 $6M 6640 devices Lid: Contains a 12V DC motor that powers a planetary gear system which controls the movement of the brushes. Clips: PLA holding device for brushes lined with foam and silicone. Uses magnets to close. Actuators: Used to lift the planetary gear system after rinse cycle to lift brushes off silicone for drying cycle. Valve: Used to control the flow of dirty water from the main cylinder. User turns it off when ready remove the water container for cleaning. Touch Screen: Provides a user interface for the device. Allows the user to track the progress of each cycle and control any individual subsystem if necessary. Final Prototype Size reduction UV sterilization Emily Eifert Dina Abdulaal Robbie Williams Heya Kaakeh Mina Mohsenian Kevin Sanabria Fan: Mounted to the back of the device and attached to the cylinder housing with a silicone tube. Fan is used for the drying cycle. Holding Mechanism vs. Axial Swirl Electronic Schematics Engineering Analysis Image J Results Device Demonstration Holding Conclusion: Axial fixture was able to clean makeup brushes more effectively than the swirl fixture. Design Integration: Clips were created to hold the brushes. Hypothesis: Axial fixture will remove more makeup than swirl. Hypothesis: Hot air will be able to remove the most mass from brushes.
