Extendable Dining Table: Mechanisms Should Be Hidden and Functional

Two states of the same dining table juxtaposed: closed at 1400mm long, extended to 2100mm long. The image shows the table in the process of being extended—the tabletop separates from the center and slides outwards to both sides, revealing a small section of the aluminum slide rails and synchronous rack underneath. The central extension leaf is being flipped up from its storage compartment beneath the table. All mechanisms are completely hidden beneath the tabletop when closed, with no tracks visible from a seated eye level. The tabletop is light oak, and the seam positions are symmetrical whether closed or extended. Neutral gray background, slightly elevated perspective to show the tabletop's split line. Avoid: depicting only the closed or fully extended single state, exposed mechanisms on the side, requiring the extension leaf to be brought separately, asymmetrical seam positions.

同一張餐桌的兩種狀態並置:收合時長 1400mm,延伸後長 2100mm。畫面呈現延伸到一半的過程——桌板從中央分開向兩側滑出,底下的鋁製滑軌與同步齒條看得見一小段,中央的延伸板正從桌下的收納槽被翻起。所有機構在收合時完全藏在桌板下方,從坐著的視線高度看不到任何軌道。桌板是淺色橡木,拼縫的位置在收合與展開時都對稱。中性灰背景,略高的視角看得見桌面的分縫。避免:畫成收合或完全展開的單一狀態、機構外露在側面、延伸板需要另外搬來、拼縫位置不對稱。
