problem statement
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

pugh chart final concept selection
Pugh ChartFinal Concept Selection
  • Criteria based on: Customer Needs Assessment, Sustainability Objective, and External Research
  • All parts: Recycled Material
  • Energy mechanism – Vibration reduction and hybrid
  • Vibration reduction ring on motor extended part (vibration rod)
  • Brush Head - Rotational/Arched Head with Gum on Head’s back:
  • Required for basic cleaning function plus gum and soft parts cleaning feature
  • Power Generation – AA-Battery + Solar Panel:
  • Reduced energy used by battery by collaborate solar power technology
  • Body Design - Thinner body/Comfortable handle:
  • Required for Customer Needs Assessment
