Proposed Concept Description
Proposed Concept Description
Our final concept is a design that incorporates the best aspects of the Ball Bearing Flat Brush and Roller Ball Bottle Brush to create our final concept. The advantages of these top concepts were fused into our final with the size of the ball bearings from the Bottle Brush being increased and the length of the bearings/plastic casing on the Flat Brush being increased. We also creating a more secure housing for the oil/serum and changed the overall shape of the device to have a larger reservoir like the Bottle Brush but be easier for a user to grip like the Flat Brush.
The final mechanism used to disperse the oil/serum for our proposed concept can be compared to how a ballpoint pen works; gravity pulls the oil/serum down and coats one half of the bearing ball and as the ball rotates in its socket, the oil/serum is transferred to the scalp. The form/grip of this concept is designed to fit either fingers or a palm through the top opening to allow the users to control the motion of the object as much as possible. The reservoir for the oil/serum sits directly on top of the bearing balls and is filled by unscrewing a cap that holds the liquid in.
The design has 4 main components/subsystems. The top casing is the first component designed to fit the average human hand with a grip of 4 fingers and the thumb sticking out, with the divots providing a more natural, comfortable grip to the hand while holding the product. The inner container is the second component. This container acts as not only a reservoir for the oil/serum but it holds the attachment plate for the ball bearings and the bearing casing. The next part is a pair of plastic pieces, one to close the silicone reservoir and plug the gaps from the handle end, preventing any leakages, while the other is a shell to secure the top casing in place.
Apart from this, we have the plastic-cased steel ball bearings which act as our delivery mechanism and are individually removable, allowing easy replacement of the moving parts most likely to fail.

In order to clean the device, refer to the architectural drawing to see how all components of the device are attached to each other. There is one silicon piece indicated in grey while the blue pieces are a harder plastic material. The flat cap and the hollow casing both fit into the silicon piece by stretching the softer material. The ball bearings and casings are press fit into the silicon cylinder bristles but can be removed by pulling down on them with a strong force.
