Elevator Destination Floor Filtering for Mobile Service Requests
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing elevator systems require passengers to make service requests at the landing, which can be cumbersome and inefficient, especially when using mobile devices, as they often present a full listing of destination floors, which can be overwhelming and cumbersome to navigate and display a subset of destination floors based on access control permissions, physical constraints, and prior knowledge of accessed floors.
Innovation Solution
A method and user device that filters the listing of destination floors based on access control permissions, physical constraints, and prior knowledge of accessed floors, allowing users to select a departure floor and destination floor through intuitive gestures or automatic determination, reducing the list of available destination floors to a manageable subset.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a full listing of all destination floors is displayed to users, then complete information is provided, but the interface becomes overwhelming and cumbersome to navigate
Solution Approach 1:
The patent extracts and displays only the relevant subset of destination floors based on access control permissions, physical constraints, and prior travel history, rather than showing all floors. This removes unnecessary information from the interface while maintaining complete relevant information, resolving the contradiction between information completeness and interface simplicity.
Solution Approach 2:
The patent applies local quality by customizing the destination floor list for each user based on their specific access permissions, building constraints, and travel patterns. Each user receives a tailored view of destination floors relevant to them, rather than a uniform complete list, improving ease of operation while preserving necessary information.
2Ease of operation
If remote elevator service requests are enabled using mobile devices, then user convenience is improved, but the system complexity increases
Solution Approach 1:
The patent implements a universal elevator management system that handles multiple functions: traditional landing-based requests, remote mobile device requests, access control verification, destination floor filtering, and elevator dispatching. By creating a multi-functional system, the patent manages complexity through consolidation rather than adding separate systems for each function.
Solution Approach 2:
The patent introduces an intermediary server that mediates between mobile devices and the elevator control system. The server handles complex tasks like verifying access permissions, filtering destination floors, and managing communication protocols, thereby shielding the elevator control system from direct complex interactions while enabling convenient remote requests.
3Adaptability or versatility
If destination floor selection requires manual input, then user autonomy is maintained, but the time required to make a request increases
Solution Approach 1:
The patent performs preliminary actions by automatically determining the user's current floor using location services and pre-filtering the destination floor list based on access permissions and prior travel history before the user makes a selection. This preliminary preparation reduces the time needed for the actual selection process while maintaining user autonomy in choosing the final destination.
Solution Approach 2:
The patent implements feedback mechanisms that learn from user travel patterns and automatically adjust the presentation of destination floors, potentially pre-selecting likely destinations based on historical data. This feedback loop maintains user choice while progressively reducing the time required for destination selection through intelligent predictions.

AI summary
Methods and systems for making elevator service requests in a building having an elevator system, the method including, determining a departure floor (504), populating, by a computing device comprising a processor, a destination floor list with at least one destination floor (506) and displaying the destination floor list on a user device (531), the destination floor list limited to a subset of all possible destination floors, and receiving at least one user input indicating a selection of a destination floor by a user and indicating a new elevator service request based on the determination of a departure floor (504) and the selection of a destination floor (506). The method also includes generating an elevator service request packet based on the new elevator service request and transmitting the elevator service request packet to an elevator controller to make an elevator service request.
