This design is the original home product of our team. The starting point of the design is to place cleaning tools such as scouring pads and steel balls on the side of the sink. The space beside the sink is too precious. It must be compact, efficient and valuable. There are many products of the same type on the market, but the storage efficiency is not high, and the storage pertinence is not clear (too much function integration). Then under the general trend of garbage classification, we feel the rigid demand of filtering kitchen waste, so the functions of the two are appropriately superimposed. Fixing is a big problem. We chose suction cups and used two. The reason is very simple, in case one suction cup breaks down, there is no problem for only one suction cup to work.
