Elevator Destination Dispatch User Interface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Elevator users face inconvenience when assigned cars are delayed, full, or less desirable, and there is no mechanism to easily switch to alternative cars that may offer faster service.
Innovation Solution
A method and system that allow users to select between the initially assigned elevator car and alternative cars by displaying both options on a user device, with the alternative car's status and favorability indicated through graphical cues, enabling users to modify their assignment to a more favorable car if desired.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the system assigns a single optimal elevator car to each user, then the elevator system operates with high efficiency and minimal wait times, but the user cannot switch to alternative cars if the assigned car is delayed or full
Solution Approach 1:
The system dynamically updates elevator car assignments and allows users to switch between primary and secondary assignments in real-time based on current elevator status. The user interface dynamically presents alternative car options when the primary car becomes unavailable, transforming a static single-assignment system into a dynamic multi-option system that adapts to changing conditions.
2Ease of operation
If the system provides real-time information about multiple elevator car options to users, then user satisfaction improves due to increased flexibility, but the system complexity increases
Solution Approach 1:
The system automatically monitors elevator car status and generates secondary assignments without requiring user intervention. When a user's primary elevator car becomes unavailable, the system proactively identifies and presents alternative car options through the user interface, allowing the system to serve itself in managing complexity while providing enhanced user convenience.
Solution Approach 2:
The user interface acts as an intermediary that simplifies the complex backend processes. It presents elevator car options in an intuitive visual format with clear indicators of primary versus secondary assignments, masking the underlying system complexity while delivering user-friendly functionality.
3Loss of time
If the system monitors and presents alternative elevator car assignments in real-time, then wait times are reduced by enabling switches to faster alternative cars, but the loss of information about car status increases without proper display mechanisms
Solution Approach 1:
The user interface employs visual indicators such as color coding to distinguish between primary and secondary elevator car assignments. This visual differentiation helps users quickly understand the status and priority of different car options without overwhelming them with text-heavy information, enabling rapid decision-making to minimize wait times.

AI summary
Methods and systems for providing and selecting multiple elevator assignments in a destination dispatching system. The method includes obtaining and presenting a primary elevator car assignment associated with a destination request, obtaining and presenting a secondary potential elevator car assignment associated with the destination request, and receiving information associated with a user selection related to at least one of the primary elevator car assignment and secondary potential elevator car assignment. The method also includes requesting, by the user device (231, 331, 431, 531), a modification of the primary elevator car assignment if the information associated with a user selection indicates a modification is desired by the user; otherwise, continuing with the primary elevator car assignment.
