Collin Russo David Tawadras Brian Johnson Engineering Design 100

To create a new innovative toothbrush that consumers will love because of the products durability, ease of use, aesthetics, and price. We will have to create new design concepts that focus on the design of energy storage, brush head design, and body shape that will appeal to most if not all consumers. The product will appeal to not only children 6+, but all adults will enjoy this product.

“To design an innovative electric toothbrush that is comfortable, easy to use, and cost efficient.”

Concept Generation Head Design: 1. The top component oscillates in a rotational motion about 120 degrees. The bottom bristles are stationary. 2. The sets of bristles in circular clusters that rotate. Top goes counterclockwise, middle goes clockwise, and bottom goes counterclockwise. 3. One cluster of bristles that shift up and down quickly. 4. There are two clusters of bristles in circle that rotate. Top is clockwise, bottom is counterclockwise. Around the circular clusters are bristles aligned in an ellipse. 5. There is one cluster of bristles that rotates side to side. Body Design: 1. Standard straight body. 2. Angled neck for a better reach. 3. Head and most of body is compactable into base. 4. Toothpaste dispenser in base of toothbrush. 5. Base has a sterilizing liquid to store brush head and keep it clean. Power Source: 1. Alkaline Batteries x2 2. Solar powered rechargeable batteries 3. Mechanical Manual Crank 4. Direct plug in to 110v power source 5. Rechargeable Lithium battery- Plug in to 110v power source to recharge internal battery

After receiving our Colgate Spin Brush, we found many flaws in the design that could’ve been redesigned. Although some designs are optimal since they are very cost efficient. For example, the brush head is an efficient design, since redesigning the head to clean teeth better would not only of raised the price dramatically, but also would’ve made it harder for production to occur. So, we decided to keep the brush head design in our newly designed toothbrush. But, we saw some things that needed to be changed, most important was the energy source. The price of the product would still increase to make this change but we found it to be very cost efficient in making the switch. Instead of the AAA batteries we included a rechargeable battery pack, that can easily be plugged in to the toothbrush and after being fully charged would last for 4 hours of use. We found that consumers hated when their toothbrushes lost power, because of poorly charged batteries. We also bent the head to 60 degrees since we found that most cavities were a result of toothbrushes not cleaning areas that are hard to reach.
