Huang Ju-wei, a student of the National Chiao Tung University Institute of Applied Arts, designed a "U-shaped scouring pad" which has a one-centimeter-wide groove down the middle of it and can be slotted over the side of a pot-this way you don't have to turn the plates around to wash the back of them, and the sponge itself can stand up and dry on an ordinary kitchen rack.
交通大學應用藝術研究所學生黃如薇設計的「Ｕ型菜瓜布」，將菜瓜布裁空出約一公分寬的凹槽，可以套在碗盤邊緣，洗盤子背面時不用費力將盤子翻過來，甚至還能站立或晾在廚房架子上。
