Elevator Door Panel 2D Adjustability via Segmented Interface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional elevator door arrangements offer limited 2-dimensional adjustability, where adjusting the position of a door panel in one direction often interferes with its position in another direction, lacking independent adjustability in horizontal directions and requiring interdependent adjustments, which complicates gap management between door panels and adjacent structures.
Innovation Solution
The proposed elevator door arrangement incorporates a door panel, a door mechanism, and an interface member with specific fixation and interconnection plate sections, allowing for 2-dimensional or 3-dimensional adjustability through oblong through-holes and fixation members, enabling independent adjustments in horizontal and vertical directions, and an optional lever mechanism for precise vertical adjustment without manual lifting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If door panels are mounted with fixed positioning, then installation is simple, but adjustability in multiple directions is limited
Solution Approach 1:
The mounting structure is segmented into separate components: a door mechanism with first fixation plate sections, door panels with second fixation plate sections, and interface members with oblong through-holes. This segmentation allows independent adjustment in multiple directions while maintaining a relatively simple overall structure.
Solution Approach 2:
The mounting structure transitions from fixed positioning to dynamic adjustability through the oblong through-holes that allow movement in multiple directions. The interface member enables the door panel to be repositioned independently in horizontal and vertical directions during installation.
2Manufacturing precision
If door panel position is adjusted in one direction, then gap dimensioning in that direction is optimized, but position in another direction becomes constrained
Solution Approach 1:
The oblong through-holes are oriented in different directions (first direction parallel to door panel extension plane, second direction perpendicular to it), enabling independent adjustment in multiple dimensions. This allows optimization of gap dimensions in each direction without constraining adjustment in other directions.
3Ease of operation
If multiple adjustment directions are enabled, then installation flexibility is improved, but adjustment procedure complexity increases
Solution Approach 1:
The interface member acts as an intermediary component between the door mechanism and door panel, providing a unified adjustment mechanism. The oblong through-holes in the interface member simplify the adjustment procedure by allowing movement in multiple directions through a single component rather than requiring multiple separate adjustment mechanisms.

AI summary
An elevator door arrangement (1) with at least 2-dimensional door panel adjustability is described. The elevator door arrangement (1) comprises at least one door panel (3), an interface member (25),and a door mechanism (5). The door panel (3) is fixedly connected to the door mechanism (5) via the interface member (25). The door panel (3) comprises a first fixation plate section (29) extending in a horizontal plane. The door mechanism (5) comprises a second fixation plate section (37) extending in a vertical plane. The interface member (25) comprises a first interconnection plate section (43) and a second interconnection plate section (45), the first interconnection plate section (43) extending parallel to the horizontal plane and the second interconnection plate section (45) extending parallel to the vertical plane. Furthermore, the first fixation plate section (29) comprises a third oblong through-hole (31) extending in a second horizontal direction (35). The first interconnection plate section (43) comprises a first oblong through-hole (47) extending in a first horizontal direction (49) being transverse to the second horizontal direction (35). The second fixation plate section (37) comprises a second oblong through-hole (39) extending in the vertical direction (41). The door panel (3) is fixed to the interface member (25) via a first fixation member (53) vertically extending through the first and optionally the third oblong through-holes (47, 31) and the interface member (25) is fixed to the door mechanism (5) via a second fixation member (61) horizontally extending through the second oblong through-hole (39), thereby advantageously establishing the 2-dimensional or even 3-dimensional door panel adjustability.
