Modular Revolving Door Assembly with Concealed Drive Unit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing revolving door designs face challenges with increased height due to drive unit placement, aesthetic disturbances, especially in glass-facade buildings, and require extensive installation and customization, leading to longer delivery times and installation complexities.
Innovation Solution
A modular revolving door assembly with a pre-assembled driving base unit that includes the drive unit, allowing the driven column to extend above it, facilitating easy adaptation and installation without the need for additional support or floor modifications, and enabling a compact, aesthetically appealing design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the drive unit is located above the door panels, then the drive unit is accessible for installation, but the height of the revolving door is increased and cover sheets are required which disturb the aesthetic appearance
Solution Approach 1:
The drive unit is nested within the central column of the revolving door, specifically positioned in the lower portion of the central column. This nesting approach allows the drive unit to be housed within the existing structural envelope without protruding outward, thereby maintaining the aesthetic appearance of the door while still providing accessible installation through the bottom opening of the central column.
2Shape
If the drive unit is located in a pit in the floor, then the aesthetic appearance is maintained, but extensive modification and rebuilding of the floor is required which is not always possible
Solution Approach 1:
The drive unit is extracted from the floor pit configuration and repositioned within the central column structure. This extraction eliminates the need for extensive floor modification while maintaining the aesthetic appearance, as the drive unit is now housed within the vertical profile of the central column rather than requiring horizontal floor excavation.
3Device complexity
If the drive unit is located in a central body, then the drive unit is integrated, but the construction becomes bulky requiring a large central body and large revolving door width
Solution Approach 1:
The drive unit is positioned in a specific local region of the central column (the lower portion) rather than distributing it throughout the entire central body. This localized positioning allows the drive unit to be integrated into the existing central column structure without requiring an increased overall volume, thereby maintaining a compact design while providing necessary integration.
4Device complexity
If the drive unit is located in a central body, then the drive unit is integrated, but the passage capacity is decreased when the total width is limited
Solution Approach 1:
The drive unit is positioned in the vertical dimension within the central column rather than occupying horizontal space in the central body. This dimensional relocation allows the drive unit to be integrated vertically within the existing width envelope, preserving the horizontal passage capacity while achieving the necessary integration of the drive mechanism.
5Adaptability or versatility
If the revolving door is customized for each installation, then the door fits specific requirements, but delivery times are increased
Solution Approach 1:
The revolving door is segmented into modular components including a standardized central column with integrated drive unit, separate door panels, and adaptable cover sheets. This segmentation allows the central column with drive unit to be manufactured as a standardized module that can be quickly assembled with different door panel configurations, thereby reducing delivery times while maintaining customization capabilities for specific installation requirements.
