Revolving Door Drum Structure With Nested Roof Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing revolving doors have complex ceiling assemblies that require external support beams or columns, leading to a tall structure and on-site assembly challenges, affecting appearance and structural integrity.
Innovation Solution
The drum elements are constructed with inner and outer glass elements having lateral offsets, allowing seamless integration of support profiles and a modular ceiling assembly that can be pre-assembled, reducing the need for external support and simplifying installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the ceiling assembly is supported by external beams or columns, then the structural stability is improved, but the appearance is degraded and the structure becomes taller
Solution Approach 1:
The support profiles are nested within the lateral offset between the inner and outer glass elements of the drum elements. The ceiling assembly is supported by these nested support profiles, eliminating the need for external beams or columns. This nesting approach maintains structural stability while preserving a clean, modern appearance without protruding support structures.
Solution Approach 2:
The invention utilizes the lateral dimension (radial offset) between the inner and outer glass elements to accommodate support profiles, rather than using vertical or horizontal extensions. This dimensional approach allows support structures to be hidden within the existing radial space, maintaining aesthetic appearance while providing necessary structural support.
2Stability of the object's composition
If the ceiling assembly is constructed as a structural unit with drum elements requiring on-site assembly, then the structural integrity is improved, but the assembly time and complexity increase
Solution Approach 1:
The ceiling assembly is segmented into modular components that can be pre-assembled and pre-tested in a controlled environment before installation. These modular segments are then easily installed on-site by simply connecting them to the drum elements, reducing on-site assembly time and complexity while maintaining structural integrity through standardized connection interfaces.
Solution Approach 2:
The support profiles and ceiling assembly components are pre-assembled and prepared in advance in a manufacturing setting. This preliminary action allows for quality control, precise alignment, and proper fastening before the components are transported to the installation site, significantly reducing on-site assembly time and ensuring structural integrity.
3Ease of manufacture
If the drum elements use a conventional single-layer construction, then the manufacturing is simpler, but the ability to integrate support profiles is reduced
Solution Approach 1:
The drum elements are constructed as composite structures with inner and outer glass elements separated by a lateral offset. This composite construction maintains the aesthetic and structural benefits of glass while creating an integrated support system within the radial offset. The support profiles are embedded within this composite structure, providing both manufacturing feasibility and enhanced adaptability for integrating ceiling support functionality.
