4. Hierarchal Customer Needs List
1.) Durability
Replaceable Head
Electrically Rechargeable
F1. - Long Lasting Durability
2.) Affordability
C.1 - Must be reasonable price
3.) Performance
F2. – Should have 2 moving heads
F3. – Heads should move in circular and back and forth motion
3.1 – Need to have a decent charge length
3.2 – Should be quiet
4.) Aesthetics
4.1 – Must be a moderate weight
4.2 – Comfortable grip
4.3 – Eye-catching color
5.) Sustainable
5.1 – Must use less plastic
Problem Statement: We need to design a sustainable electric toothbrush with a focus on durability and affordability.

6. Morph Chart Function Means Energy Mechanism Brush Head
Body Form Design
Power 1
Motor in middle of brush vibrating metal rod moving brush head
Two moving parts of the head, one going back and forth and another going ciruclar
Recycled materials from water bottles or yogurt cups or Styrofoam cups.
Rechargeable battery with a charging dock 2
Motor oscillates metal rod connected to brush head.
-moves brush head up and down.
-top part of head moves in a circular motion back and forth
Have different options for brush heads, one going back and forth, one just a circular motion, and one of both
Make the case very fitting to the battery. Make sure there is no wasted plastic, case should be as form fitting as possible.
The toothbrush plugs in directly to the wall 3
Use an up and down motion in the motor
1 moving circular head and 2 moving linear heads
Include a grip in the handle
Rechargeable with built in battery supply. The battery powers motor. Light on brush indicates when battery is running low and needs recharged. 4
Connect the motor and rod to a wheel so as the wheel moves the head moves.
1 moving circular head and 1 moving linear head. The circular on top and the linear on the bottom.
Plastic should be thick so it is durable
Solar powered
-have mini solar panals attached to the back of the toothbrush body 5
Circular motion of motor that vibrates the head directly.
Recycle the heads and use the plastic from the the recycled heads to make the new toothbrush heads
Plastic should only be used from recycled materials
Small calculator sized solar panel to assist in recharging

7. Generated Concepts Energy Mechanism Brush Head Body Design Power
-Motor oscillates causing a metal rod to move up and down
-Rod moves a brush head up and down
Brush Head
-Three moving parts
-One circular oscillating and two parallel linear up and down
Body Design
-Straight with finger grips on front and back for comfort
Power
-Rechargeable high power battery included with charging dock

-Complete Electric Toothbrush Design
-Charging Station

10. How It Works Power Generation
-A motor powered by a rechargeable battery oscillates.
-A metal rod connected to motor moves up and down
-This causes the three moving parts of the brush head to move in their respective ways. (Circular oscillations, and two opposite linear motions)

11. Conclusion The design meets all customer needs
-Durability – Long lasting, and replaceable brush head
-Sustainability – Recycled Materials
-Grip – Comfortable finger grip included
-Brush Head – Three moving parts on head
