Revolving Door Drive Ring Mounting Arrangement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Revolving doors require a robust and rigid ceiling construction for the drive motor, transmission, and bearing, which increases the height and weight, posing challenges during installation and risking worker injury.
Innovation Solution
A drive ring with a circular reinforcement element and hook elements that facilitate secure mounting by allowing the drive ring to be lifted over the hook elements, which pivot and return to secure the ring in place, reducing the need for heavy ceiling structures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a robust and rigid ceiling construction is used to mount the drive motor, transmission, and bearing, then the structural strength is improved, but the weight and height of the ceiling construction increase
Solution Approach 1:
The ceiling construction is segmented into a heavy load-bearing ceiling and a separate, lighter drive ring that provides localized reinforcement. The drive ring is divided into multiple sections with connecting parts that can be independently mounted to the ceiling, allowing the heavy structural load to be separated from the mounting function.
Solution Approach 2:
The drive ring acts as an intermediary element between the ceiling construction and the drive motor/transmission assembly. It provides a robust mounting surface without requiring the entire ceiling construction to be heavily reinforced, thus reducing overall weight while maintaining structural integrity.
2Strength
If a robust and rigid ceiling construction is used to mount the drive motor, transmission, and bearing, then the structural strength is improved, but the height of the ceiling construction increases
Solution Approach 1:
The mounting system is segmented into a ceiling-mounted drive ring and a separate drive motor assembly. This allows the drive motor to be positioned at optimal height for door operation while the ceiling construction maintains its original height, avoiding unnecessary increase in overall building height.
Solution Approach 2:
The drive ring serves as an intermediary mounting platform that allows the drive motor and transmission to be positioned without requiring increased ceiling height. It provides the necessary structural support at the existing ceiling level, eliminating the need to raise the ceiling construction.
3Ease of manufacture
If the drive ring is lifted by construction workers during installation, then the drive ring can be mounted to the ceiling construction, but the considerable weight poses security risks and potential injury
Solution Approach 1:
The drive ring is segmented into multiple sections with connecting parts that can be independently handled and assembled. This allows workers to install the drive ring in manageable sections rather than lifting and securing the entire heavy ring at once, significantly reducing security risks and the potential for injury.
Solution Approach 2:
The drive ring is pre-assembled with connecting parts and mounting features during manufacturing. This preliminary preparation allows for safer and more efficient on-site installation, as workers only need to secure pre-configured components rather than assembling and lifting the entire heavy structure during installation.
4Device complexity
If the drive ring is made as a single integrated piece, then the number of components is reduced, but the weight and difficulty of installation increase
Solution Approach 1:
The drive ring is divided into multiple sections with connecting parts that can be independently handled and assembled. This segmentation reduces the weight and size of individual components, making them easier to install while maintaining the functional integrity of the complete drive ring structure.
Solution Approach 2:
Multiple drive ring sections are merged through connecting parts to form the complete drive ring structure. This combining approach allows for easier installation of individual sections while achieving the functional equivalent of a single integrated piece, balancing component simplicity with installation ease.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides a stable and secure mounting system that reduces the weight and height of the ceiling construction, enhancing safety during installation and maintaining structural integrity.
