Elevator Selection via Destination Call Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing elevator allocation methods do not allow users to interactively select the most suitable elevator car based on their individual needs, relying solely on logistical and economic algorithms that do not consider user preferences or specific requirements.
Innovation Solution
A method that enables users to lodge a destination call, determine and select a preferred elevator car from a group identified by the destination call control unit, and receive guidance to the selected elevator car through a communications unit, allowing for personalized elevator selection based on individual needs, such as accessibility or convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the destination call control unit automatically determines the elevator car using a program-based allocation algorithm, then the allocation efficiency and productivity are improved, but the user loses influence and cannot select based on individual needs
Solution Approach 1:
The system dynamically adjusts the allocation process by allowing users to intervene and select from a group of pre-determined elevator cars. The control unit first automatically determines a group of suitable cars based on efficiency criteria, then enables user selection from this group, combining automated efficiency with user flexibility.
Solution Approach 2:
The allocation process is segmented into two stages: first, the control unit automatically determines a group of suitable elevator cars based on efficiency algorithms; second, the user selects from this pre-filtered group. This segmentation maintains efficiency while enabling user choice.
2Loss of information
If the system displays all status data and requires user agreement through floor call control, then the user information awareness is improved, but the operation complexity and time consumption increase
Solution Approach 1:
The system extracts and displays only the essential information needed for user decision-making (group of suitable elevator cars) rather than all possible status data. This reduces information overload while maintaining user awareness sufficient for informed selection.
Solution Approach 2:
The control unit performs preliminary analysis and pre-determines a group of suitable elevator cars before presenting options to the user. This preliminary action filters the choices and simplifies the user's decision-making process.
3Speed
If the destination call control unit determines the elevator car without user input, then the allocation speed is improved, but the user experience and personalized service deteriorate
Solution Approach 1:
The system dynamically balances speed and user experience by first quickly determining a group of suitable elevator cars through automated algorithms, then allowing brief user selection from this group. This maintains high allocation speed while enabling personalized user choice.
Solution Approach 2:
The system performs partial automation by determining only a group of suitable cars rather than automatically selecting one, leaving the final choice to the user. This partial action maintains speed while improving user experience.
Data Source
AI summary
A method, an elevator system control unit, computer-readable media and an elevator installation for allocation of a user to the elevator installation, which is provided with a plurality of elevator cars and with a destination call control unit, wherein the user lodges a destination call at the destination control unit using a communications unit. The destination call control unit determines a group of elevator cars for serving the destination call and makes the group known to the user by the communications unit. The user selects an elevator car from the group by the communications unit. In addition, information for guiding the user to the selected elevator car is communicated to the user by the communications unit.
