This project is positioned as the basic parity in the customer's product line, because it is a design project that is typically cost-oriented and targeted at the largest audience base in the market. The balance of design and cost in this project is the key and difficult point.

Doing an oval soft adhesive like the kookaburra will increase the thickness and increase the possibility of retching.
We should learn from Panasonic, make the thickness of the bottom plate of the brush head 3.2mm, and then drive the magnet to rotate through a linear motor similar to DL system or a crank slider structure similar to EW-1150 like a plunger pump, or a EW-1031 rotating motor to adsorb or repel another magnet connected with the main shaft of the return spring to realize telescopic movement.
In this way, the back of the brush head will not knock teeth, at most a small circle at the top may bump teeth, and the possibility of knocking teeth can be greatly avoided by turning on the front and back of the area.
However, the crank slider structure or the rotating magnet telescopic structure does not require complicated electronic circuits such as micro-inverters, and can further reduce the cost by using the structure of a dry battery box-or make a chewing gum lithium battery similar to Nokia's old mobile phone, which has a special shape but allows replacement, and replaces wireless charging with a quick battery change design (Panasonic's long needle battery that does not weld to death can also be used).
In this way, there is no place to repair the aging of the battery. A SURI replaceable battery toothbrush in the UK can raise 2 million pounds, with repairable as its selling point. Is it not copying Panasonic's quick battery replacement design?
Not good at learning Panasonic's later models, but still jumping around in the vertical pendulum routine of Panasonic's early EW-1000 era (Optiva acquired by Philips is also a product of this routine, and at most the disc vertical pendulum motor has better noise reduction). As a result, even the Bass horizontal tremor brushing method does not conform to the direction of the Bass horizontal tremor brushing method, which is really boring.
Otherwise, the lower cost is the thing that the rotating motor drives the semicircular eccentric shaft. There are a lot of postage in 19.9 yuan on the market. The newly-opened molds are not unique and can't be sold. The small quantity and price are also expensive. I'm afraid it is difficult to recover the cost.
this is good
so strong
Black and white is the classic color forever
I feel that the ratio of brush head to brush handle is a bit strange. The brush head is a bit short.
Simple style
this one looks good
