Double-Deck Elevator Pantographic Mechanism Side Relocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing double-deck elevator with a pantographic mechanism between the cars has a limited story height adjustment range, making it unsuitable for buildings with relatively small story heights, restricting building design flexibility.
Innovation Solution
A double-deck elevator design where the linking mechanism, such as a pantographic mechanism, is positioned along the sides of the cars instead of between them, allowing for a greater range of story height adjustment by eliminating the need for a supporting frame and enabling cars to move closer together.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the pantographic mechanism is arranged between the two cars, then the structure is stable, but the story height adjustment range is limited
Solution Approach 1:
The pantographic mechanism is relocated from the vertical space between cars to the horizontal side spaces of the cars. This dimensional shift allows the mechanism to operate in a different spatial plane, eliminating the need for a supporting frame while maintaining structural stability and enabling greater story height adjustment range.
Solution Approach 2:
The supporting frame that previously connected the pantographic mechanism between the cars is completely removed. The mechanism is extracted from its traditional position and reconfigured to attach directly to the side surfaces of the cars, simplifying the overall structure while achieving the desired functionality.
2Adaptability or versatility
If the pantographic mechanism is arranged between the two cars, then the mechanism is stable, but the building design freedom is restricted
Solution Approach 1:
By moving the pantographic mechanism to the side spaces and operating it in a horizontal plane rather than vertical space, the invention enables buildings with smaller story heights to accommodate the double-deck elevator, thereby increasing building design freedom without compromising operational stability.
3Adaptability or versatility
If the linking mechanism is arranged between the two cars, then the structure is compact, but the story height adjustment range is limited
Solution Approach 1:
The linking mechanism is repositioned to utilize the horizontal side spaces of the cars rather than the vertical space between them. This allows the mechanism to extend outward horizontally while enabling the cars to approach each other more closely vertically, thereby expanding the story height adjustment range without increasing the volume between the cars.

AI summary
To provide a double-deck elevator characterized by the fact that by increasing the story height adjustment range in the direction in which the two cars approach each other, it is possible to increase the degree of building design freedom. Two up/down cars (6), (7) arranged in outer frame (5) are connected with each other by means of pantographic mechanisms (11) that can effect an expansion and contraction operation, and the two cars (6), (7) are driven to move towards each other or away from each other by means of pantographic mechanisms (11). The pantographic mechanisms (11) are arranged in the spaces between vertical beams (5a) and the two cars (6), (7) and each has a pivot point at the longitudinal central portion of vertical beams (5a) extending vertically in outer frame (5). Due to the pantographic mechanisms (11), the story height adjustment range in the direction in which the two cars (6), (7) approach each other is not restricted.
