Elevator Evacuation Mode Request Switch
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing elevator systems are inefficient when evacuating a large number of users from a rescue floor during emergencies, as they require specific user input for evacuation operations.
Innovation Solution
An elevator device with an evacuation operation mode request switch on the rescue floor allows continuous operation between the rescue floor and the evacuation floor, enabling efficient evacuation of people left in a building by automatically moving the car to the evacuation floor upon activation of the switch.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a call input device for specific persons is used for evacuation, then priority evacuation for individuals who operated the device is achieved, but evacuation efficiency for large numbers of users deteriorates
Solution Approach 1:
Instead of requiring users to actively operate a call input device to initiate evacuation, the system inverts the approach by automatically detecting emergency conditions and initiating evacuation mode. The evacuation operation mode request switch is automatically activated when emergency conditions are detected, eliminating the need for individual user actions while enabling mass evacuation.
Solution Approach 2:
The elevator system performs self-service by automatically detecting emergency conditions and initiating evacuation operations without requiring manual input from users. The operation control device monitors system status and automatically activates the evacuation operation mode when necessary, allowing the system to serve itself during emergency situations.
2Reliability
If manual operation of call input device is required for each evacuation, then individual evacuation control is achieved, but overall evacuation time increases
Solution Approach 1:
The system performs preliminary action by pre-configuring the evacuation operation mode and having the operation control device ready to automatically initiate evacuation when emergency conditions are detected. The evacuation routes, car assignments, and control logic are all prepared in advance, allowing immediate activation without manual intervention during the critical emergency response phase.

AI summary
An elevator device enabling efficient evacuation of people left in a building is provided. The elevator device includes: an evacuation operation mode request switch provided in a hall of an elevator on a rescue floor; a car that if the evacuation operation mode request switch is kept in an operated state, keeps operating in an evacuation operation mode in which the car moves between the rescue floor and an evacuation floor; and an operation control device that is provided in the hall of the elevator on the rescue floor, and if the operation control device is operated when the car is stopped at the rescue floor, moves the car to the evacuation floor.
