Priority-Based Multi-Display Elevator Content Control During Failures
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing elevator systems lack efficient control mechanisms to manage and prioritize application content across multiple displays in response to system status changes or display failures, potentially disrupting critical functionalities.
Innovation Solution
A control system comprising a processor and memory configured to control application content on multiple displays associated with an elevator system, prioritizing content based on predefined priorities and responding to triggering events such as system status changes or display failures by reallocating content across displays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple displays are used to provide diverse application content (ads, videos, information), then the versatility and passenger experience are improved, but the complexity of managing and prioritizing content during system disruptions increases
Solution Approach 1:
The system pre-establishes priority levels for different application contents (e.g., emergency information > advertisements > entertainment) before disruptions occur. When a disruption is detected, the controller immediately reconfigures displays based on pre-defined priorities without needing to analyze or decide in real-time, thus managing complexity while maintaining versatility.
Solution Approach 2:
The display configuration dynamically adapts based on system status. The controller monitors elevator system conditions and automatically adjusts which applications are displayed on which displays according to current priorities, allowing the system to transition between normal versatile operation and disrupted priority-based operation seamlessly.
2Productivity
If the system maintains all application contents on all displays during normal operation, then content availability is maximized, but critical functionalities may be disrupted during system failures
Solution Approach 1:
The system pre-configures priority hierarchies for application contents, ensuring that critical functions (such as emergency alerts, floor information, and operational status) are always designated as higher priority than non-critical content (ads, videos). This preliminary arrangement ensures that during failures, critical content is automatically preserved while non-critical content is displaced.
Solution Approach 2:
The system prepares for potential disruptions by establishing redundant content allocation paths and priority buffers. When a failure occurs, the pre-established priority structure acts as a cushion, protecting critical functionalities from disruption while allowing non-critical content to be temporarily displaced without affecting system safety or essential operations.
3Reliability
If the controller reallocates content across displays in response to disruptions, then critical functionalities are maintained, but the responsiveness and speed of content switching must be extremely fast
Solution Approach 1:
The controller pre-maps priority levels to specific application contents and maintains ready-to-deploy content configurations in memory. When a disruption is detected, the system retrieves pre-prepared content allocations rather than generating new ones, enabling extremely fast switching (within milliseconds) while maintaining functional reliability.
Solution Approach 2:
The system uses replicated content configurations stored in memory, where multiple versions of application contents are pre-loaded with associated priority metadata. During disruptions, the controller copies and deploys the appropriate pre-configured content combinations to affected displays, avoiding the need for complex real-time content generation or negotiation, thus achieving both speed and reliability.

AI summary
A control system includes at least one processor and at least one memory including computer program code. The at least one memory and the computer program code is configured to, with the at least one processor, cause the control system to at least perform: controlling application contents displayed by a plurality of displays associated with an elevator system, each application content having an associated respective priority; obtaining a triggering event associated with the elevator system; and changing application content of at least one of the plurality of displays based on the triggering event and the priority associated with each of the application contents.
