Description of Design

This design was original from the mill wheel. I use it to train kids to use the urinal correctly. And I also add a musicbox to it for calling the attention of the kids. The reason why I used the wheel in this way is that I find if I play some music to the kids when they are doing something, they may behave more excited and doing things more quickly and correctly. The set could be separated into 3 parts, the wheel, the gearing and the musicbox. You can see it clearly in the 3 pictures attached. If the wheel is running, the gearing system will pass the power to the musicbox and make the musicbox playing the music. The musicbox is the mechanical one which is running without electric power. The gearing transmission system contains a worm and a wormgear. It is simple but useful. The wheel, that I have designed several styles, was the main part of the design. I use the color of red to make it more clearly.
