Hybrid Toothbrush
by Team 8• Taylor Beatty• Zack Miller• Cole Fenton• Hoang Dinh
Design ActivitiesPresented with a
problem statement of creating a more
sustainable toothbrush for Oral
B customers
Evaluated toothbrush and its
qualities (aesthetics, power, design)
Dissected toothbrush to determine parts
and evaluate how the brush worked
Created a customer needs assessment to reach goal of creating
a more sustainable toothbrush that
pleased the buyers
Created an AHP chart based on the
customer assessment
Concept generation for Brush Head Design, Energy
Mechanisms, Power Generation, Body
Design
Created a morph chart with ideas
that were generated
Generated Pugh charts based on
morph charts
Determined a final concept based on the rankings from the Pugh Charts

PROBLEM STATEMENT
• create a more sustainable toothbrush that is pleasing to the customers– Minimize the size of toothbrush, less material
would be used – Different shape for aesthetics and a better clean– Changing the type of batteries we can extend the
battery life of the toothbrush
