An automated coupling mechanism for sliding doors that are movably mounted upon a storage unit. The coupling mechanism may comprise a rotating mechanism comprising a rotating member, and connecting unit. The storage unit may comprise at least one outer sliding door and at least one inner sliding door comprising an upper track, where the connecting unit connect the rotating mechanism to the outer sliding door. The rotating member and the track may be made from material of substantially high friction coefficient to enable the rotating member to move the inner sliding door along the track when rotated. The connecting unit, which are connect the rotating mechanism to the outer sliding door, may enable the outer sliding door to move in the opposite direction of the inner sliding door, whereby the inner sliding door is moved by the rotating mechanism as a physical counteraction.
