Elevator Content Personalization and Passenger Pairing Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Elevator systems lack passenger control over multimedia content and passenger pairing, leading to negative ride experiences due to mismatched interests and content preferences.
Innovation Solution
An intelligent building system uses passenger identification to select and provide multimedia content and group passengers based on their social network data, allowing for personalized content and compatible passenger pairing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If destination dispatching systems optimize service speed by assigning passengers to elevators using algorithms, then service efficiency is improved, but passenger choice over content and companion pairing is lost
Solution Approach 1:
The system dynamically adjusts elevator assignment by integrating real-time passenger preferences (content interests, companion choices) with service efficiency algorithms. The dispatching system transitions from static algorithmic assignment to dynamic decision-making that adapts to passenger preferences while maintaining service optimization.
Solution Approach 2:
The system collects and stores passenger preference data (content interests, companion preferences) in advance before elevator assignment. This preliminary data collection enables the dispatching system to make informed decisions that satisfy both service efficiency and passenger preferences without compromising either objective.
2Device complexity
If pre-selected content is provided in elevators without regard to passenger identity, then system complexity is reduced, but passenger satisfaction deteriorates
Solution Approach 1:
The system implements feedback loops where passenger responses to content preferences are collected and used to refine future content selections. This feedback mechanism enables personalized content delivery without requiring complex real-time analysis, as the system learns from passenger responses over time.
Solution Approach 2:
Passengers actively participate in selecting their preferred content and companions through the system interface. This self-service approach reduces system complexity by shifting some decision-making responsibility to passengers while improving satisfaction through personalized selections.
3Adaptability or versatility
If passenger identification and social network data are integrated into the elevator system, then personalized content delivery and passenger pairing are improved, but system complexity increases
Solution Approach 1:
The system integrates multiple functions (passenger identification, content selection, companion pairing, service optimization) into a unified elevator control platform. This multi-functionality approach consolidates complexity into a single system rather than adding separate systems, making the complexity more manageable while delivering personalized services.
4Speed
If passengers are assigned elevators based solely on service optimization algorithms, then service speed is improved, but negative ride experiences increase due to mismatched interests
Solution Approach 1:
The system changes the parameters of elevator assignment from purely time-based optimization to include preference-based matching dimensions. By adding content interest compatibility and companion preference as additional parameters, the system maintains service speed while eliminating negative experiences caused by mismatched passenger groupings.

AI summary
The disclosure herein includes a method (200) for controlling elevators by an intelligent building system. The method (200) includes receiving, by the intelligent building system, elevator calls initiated by passengers (210). Each elevator call can include a passenger identification corresponding to a passenger initiating the elevator call. The method further includes procuring passenger preference information based on the passenger identifications in response to the elevator calls (220) and procuring content with respect to the passenger preference information. The method further includes controlling output devices to provide said content to the passengers.
