Occupant-Aware Elevator Dispatch With Dynamic Isolation Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Elevator systems fail to account for individual occupants or potential occupants, neglecting observable or assigned attributes, importance, environmental context, and user preferences, and do not provide dynamic isolation or adjustment of elevator movement and internal car environment.
Innovation Solution
An elevator control system that prioritizes occupant delivery based on contextually classified information, including IoT observed inputs, object detection, and environmental information, enabling dynamic monitoring and adjustment of elevator settings and policies for enhanced logical delivery and isolation responses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional elevator control systems are used, then basic elevator operation is maintained, but individual occupant attributes, preferences, and contextual information are not accounted for
Solution Approach 1:
The system segments occupants into different priority categories (e.g., VIP, regular, isolated) based on their attributes and contextual information. This segmentation allows the elevator control system to apply different dispatching strategies to different groups, enhancing adaptability without requiring complete system redesign.
Solution Approach 2:
The patent introduces an intermediary layer between the traditional elevator control system and the occupants. This intermediary processes occupant attributes, preferences, and contextual information, then translates them into dispatching decisions. The intermediary absorbs the complexity while presenting a simplified interface to both occupants and the base control system.
2Productivity
If elevator systems monitor and respond to individual occupants, then passenger delivery efficiency and security are enhanced, but system complexity and resource consumption increase
Solution Approach 1:
The system enables occupants to self-identify and self-categorize through various means (e.g., RFID cards, mobile apps, biometric recognition). Occupants actively provide their own attributes and preferences, reducing the burden on the monitoring system to extract this information passively, thereby lowering complexity while maintaining high productivity.
Solution Approach 2:
The patent dynamically changes system parameters such as elevator dispatch priority, door hold duration, and car destination based on occupant attributes and real-time conditions. By adjusting these parameters rather than redesigning the entire control architecture, the system achieves high productivity with manageable complexity.
3Reliability
If dynamic isolation responses are implemented for individual subjects, then facility security is enhanced, but elevator control complexity increases
Solution Approach 1:
The system performs preliminary identification and categorization of occupants before they enter the elevator. Potential isolation candidates are identified in advance based on their attributes, and isolation protocols are pre-configured. This preliminary action simplifies the real-time control complexity by preparing isolation responses beforehand rather than making complex decisions during elevator operation.
Solution Approach 2:
The patent extracts the isolation control logic as a separate, specialized module within the overall elevator control system. This extracted module handles isolation-specific complexities independently, allowing the main elevator control system to remain relatively simple while still providing enhanced security through targeted isolation responses for specific occupants.
Data Source
AI summary
A method, system, and computer program product for occupant-based elevator actions are provided. The method identifies a set of subjects approaching a set of elevators to generate a set of identities for the set of subjects. A set of initial priority statuses are generated for the set of subjects. Based on the set of identities and the set of initial priority statuses, an elevator dispatch solution is determined. The method updates at least a portion of the initial priority statuses to generate a set of subsequent priority statuses in response to a subset of subjects entering at least one elevator. The method determines an isolation response for a first subject of the subset of subjects and modifies the elevator dispatch solution based on the isolation response to generate an isolation dispatch solution. The at least one elevator executes the isolation dispatch solution.
