Elevator Access System Dynamic Mode Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current elevator access systems are inflexible, as they either require identification for secure access or operate in anonymous mode, failing to seamlessly integrate both modes, which can be inadequate in various scenarios.
Innovation Solution
An elevator system with an access control method that identifies individuals using sensor data from various devices, switching between personal and anonymous modes based on identification, allowing flexible access control and prioritization of elevator services, even when a remote identification system is unavailable.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the elevator system requires identification for secure access, then security is improved, but flexibility and ease of use deteriorate
Solution Approach 1:
The elevator access system dynamically switches between personal mode (requiring identification) and anonymous mode (no identification required) based on real-time sensor data and user presence detection. This dynamic adaptability resolves the contradiction by allowing the system to be secure when needed and flexible when appropriate, rather than being locked into a fixed access mode.
Solution Approach 2:
The system integrates multiple identification methods (biometric sensors, RFID readers, facial recognition cameras) and multiple access modes (personal and anonymous) into a single universal access control system. This multi-functionality allows the elevator to serve both security-conscious scenarios and convenience-oriented scenarios without requiring separate systems.
2Ease of operation
If the elevator system operates in anonymous mode, then ease of use is improved, but security deteriorates
Solution Approach 1:
The system dynamically adjusts its security level based on the operational context. When operating in anonymous mode for ease of use, it can switch to personal mode when security requirements arise, such as during emergencies or when unauthorized access is detected. This dynamic adjustment resolves the contradiction between ease of use and security.
Solution Approach 2:
The system continuously monitors sensor data, access patterns, and system state to provide feedback that triggers mode switching. When feedback indicates a security concern (e.g., suspicious behavior, emergency situation), the system transitions from anonymous mode to personal mode, thereby maintaining security while preserving ease of use during normal operation.
3Adaptability or versatility
If the system switches between personal and anonymous modes, then flexibility is improved, but system complexity increases
Solution Approach 1:
The patent combines multiple identification technologies (biometric sensors, RFID readers, facial recognition cameras) and control functions into a single integrated access control system. This merging reduces the overall system complexity compared to having separate systems for each identification method, while still providing the flexibility to switch between personal and anonymous modes.
Solution Approach 2:
The system employs an intermediary control unit that manages the switching between personal and anonymous modes based on sensor data and system state. This intermediary layer simplifies the complexity by centralizing the decision-making logic for mode switching, rather than requiring complex coordination between multiple independent subsystems.
4Reliability
If identification is required for floor access, then security is improved, but productivity and access speed deteriorate
Solution Approach 1:
The system performs preliminary identification actions before the user actually needs to access the elevator. Sensors detect user presence and pre-process identification data (such as facial recognition or RFID reading) while the user is still approaching, so that when the user reaches the elevator, access can be granted immediately without delay. This preliminary action maintains security while preserving access speed.
Solution Approach 2:
The system replaces traditional mechanical key-based access systems with automated sensor-based identification (biometric sensors, RFID readers, facial recognition cameras). This substitution eliminates the need for physical key exchange and manual verification, thereby maintaining security through automated identification while significantly improving access speed and user productivity.

AI summary
A method for identifying a person by an elevator system (10, 10', 10") comprises: acquiring identification data (48) of the person with an identification device (46); matching the identification data (48) with user profiles (52) of a plurality of persons, which user profiles (52) are stored in an identification database (34); when a user profile (52) is found based on the identification data (48): switching in a personal mode, which is associated with the user profile (52) and interacting with the person in the personal mode; and when no user profile (52) is found: switching in an anonymous mode, and interacting with the person in the anonymous mode.
