Automatic Passage Gate with Rotatable Base for Emergency Evacuation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automatic passage gates do not efficiently allow people to exit during emergency situations, often resulting in congested and potentially hazardous evacuation conditions.
Innovation Solution
An automatic passage gate with a sliding panel portion for normal operation and a rotatable base portion during emergencies, enabling a larger passage area for fast and secure evacuation, activated either manually or automatically through a controller system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the passage gate uses a sliding panel portion for normal operation, then space efficiency and security are improved, but the passage area is limited during emergencies
Solution Approach 1:
The gate structure transitions from a static sliding panel to a dynamic configuration where the base portion can rotate. During normal operation, the panel slides horizontally for secure closure. During emergencies, the base portion rotates 180 degrees to create a larger passage area, allowing the gate to adapt its geometry based on operational requirements.
Solution Approach 2:
The gate evolves from one-dimensional horizontal sliding motion to two-dimensional movement by adding rotational capability to the base portion. This dimensional change allows the gate to achieve a larger passage area during emergencies while maintaining its compact sliding structure for normal operations.
2Productivity
If the passage gate is kept closed during emergencies, then security is maintained, but evacuation efficiency deteriorates
Solution Approach 1:
The gate is pre-configured with a rotatable base portion that can quickly transform from a closed position to an open evacuation position. This preliminary structural preparation allows for rapid deployment during emergencies without compromising security during normal operations, as the rotation mechanism is already in place but not activated until needed.
Solution Approach 2:
The gate system changes its operational parameters from a closed state with limited passage to an open state with expanded passage area. The rotatable base portion enables this parameter change by rotating 180 degrees, transforming the gate's geometry to accommodate high-volume evacuation while maintaining secure closure during normal operations.
3Ease of operation
If the gate structure is simplified for easy operation, then ease of operation is improved, but the ability to provide larger passage area during emergencies deteriorates
Solution Approach 1:
The gate is divided into two functional segments: a sliding panel portion for normal operation and a rotatable base portion for emergency evacuation. This segmentation allows each part to perform its specific function independently - the panel provides secure sliding closure while the base portion enables rapid rotation to create a larger passage area when needed.

AI summary
A passage gate for allowing or preventing people to enter or to exit a passage area comprising a base portion (110) and a panel portion (120) is provided. The passage gate (100) is configured to be driven in a first operation mode and a second operation mode. When the passage gate (100) is driven in the first operation mode the panel portion (120) is slidable relative the base portion (110) between a first open position, allowing people to pass, and a closed position preventing people from passing through the passage gate (100). When the passage gate (100) is driven in the second operation mode the base portion (110) is rotatable between the closed position and a second open position for achieving a larger passage area.
