In the past, the coaster was always plagued by small water droplets due to physical effects. The new structure consisted of a cup groove with a circular groove and a small potted component, which concentrated the water droplets on the circular grooved cup. At the bottom of the pad, and using water to flow down to another small potted component, you can use a small potted plant to absorb the water source, so you can make good use of the multi-purpose coaster that collects the water bead function.以往的杯墊因物理作用總是會有小水珠而弄濕辦公桌的困擾,本新型結構包含有一圓形凹槽的杯墊及一小盆栽元件,將水珠集中在圓形凹槽杯墊底部,並利用水往低處流,再流向另一小盆栽元件,可做小盆栽中植物吸收水份來源,如此,即可善用集水珠功能的多用途杯墊。
