Step Brocade: Rhythm Composed of Short and Long Lattices

A wooden lattice door with a 'bubujin' (step-by-step brocade) pattern. The pattern is formed by interlocking horizontal and vertical mullions of varying lengths: the central area has larger square grids, and moving outwards, shorter mullions gradually appear, subdividing the grids into smaller rectangles, thus the grid size decreases from the center to the edge, creating a clear rhythm of density. All mullions have the same cross-section, only two directions (horizontal and vertical), with no diagonal or curved lines, making the overall design extremely rational. The mullions are dark solid wood, and the grids are either left open or covered with translucent paper. Light passes through from behind, casting corresponding grid shadows on the floor. Avoid: making the grid sizes completely uniform without density variation, adding diagonal or curved lines, making the mullions of varying thickness, filling the grids with colored glass.

一扇步步錦圖案的木格門。圖案由長短不一的橫櫺與豎櫺搭接而成:中央區域是較大的方形格眼,往外圍逐漸出現較短的櫺條把格眼細分成更小的長方形,因此格眼的尺寸從中心往邊緣遞減,形成明確的疏密節奏。所有的櫺條斷面相同、方向只有橫豎兩種、沒有斜線與曲線,整體極為理性。櫺條是深色的實木,格眼內是留空或糊著半透明的紙。光從背後透過來,在地面投下對應的格影。避免:讓格眼的尺寸完全一致沒有疏密、加入斜線與曲線、把櫺條做成粗細不一、用彩色玻璃填滿格眼。
