Slidable Revolving Door Wings for Dynamic Passage and Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional revolving doors lack versatility and flexibility in use, failing to adapt to varying needs and conditions, such as high-security demands, quick passage of large numbers of people, and resistance against draughts and breaking attempts.
Innovation Solution
The revolving door features slidable door wing parts that can be positioned in multiple configurations relative to the central axis and walls, allowing for radial movement and retraction to enhance usability, security, and draught resistance, with sensor-activated functions for dynamic operation and obstruction avoidance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional revolving doors are used, then the structure is simple and easy to manufacture, but the versatility and flexibility in use are limited
Solution Approach 1:
The door wing parts are made dynamically adjustable through sliding mechanisms, allowing them to change position between extended and retracted states. This enables the revolving door to adapt to different operational modes (security mode, high-traffic mode, panic mode) without requiring multiple different door structures, thus improving versatility while managing complexity through a single adjustable system
Solution Approach 2:
The revolving door is designed with door wing parts that can perform multiple functions: they can extend to provide security and draught resistance, retract to allow rapid passage of people, and be positioned in intermediate states for controlled access. This multi-functionality is achieved through the sliding mechanism that allows the same structural elements to serve different purposes based on operational requirements
2Reliability
If door wings are extended for security, then resistance against breaking and entry is improved, but passage speed decreases
Solution Approach 1:
The door wing parts can dynamically change their position from extended (providing security) to retracted (enabling fast passage). The sliding mechanism allows rapid transition between these states, so the door can provide maximum security when needed and then quickly open for rapid evacuation or high-traffic periods, resolving the contradiction between security and passage speed
3Object-affected harmful factors
If door wings are extended for draught resistance, then wind resistance is improved, but flexibility in use is reduced
Solution Approach 1:
The door wing parts can dynamically adjust their position to extend during windy conditions to block draughts and gaps, then retract when flexibility is needed for various operational modes. This dynamic adjustment capability allows the same structure to provide both excellent draught resistance and operational flexibility, eliminating the need to choose one fixed configuration over the other
4Productivity
If slidable door wing parts are retracted for quick passage, then passage efficiency is improved, but security and draught control are reduced
Solution Approach 1:
The door system can dynamically retract door wing parts to maximize passage efficiency during high-traffic periods, then extend them to restore security and draught control. The sliding mechanism enables rapid transition between these states, allowing the door to optimize for passage speed when needed while maintaining the capability to provide full security and environmental control when required

AI summary
Revolving door comprising a wall or walls in which openings for inlet and outlet of persons and/or objects are provided, and rotatable door wings that during use are rotatable around an imaginary central vertical axis in a passage area surrounded by the wall or walls, wherein each of said door wings is provided with a slidable door wing part for extending and/or retracting the door wing of which it forms a part, wherein each of said door wings substantially comprises slidable door wing parts only so as to provide that the slidable door wing parts of any single door wing are selectable to be placed in at least two positions, a first position wherein said door wing parts are entirely adjacent or next to each other and wherein edges of said door wing parts are adjacent to the wall or walls, and wherein said door wing parts extend radially away from said wall or walls towards the imaginary central vertical axis, and a second position wherein said door wing parts are entirely adjacent or next open opening or to each other and wherein edges of said door wing parts are adjacent to the central vertical axis, and wherein said door wing parts extend radially away from the central vertical axis towards the wall or walls.
