Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing elevator systems face issues with passenger-operated control panels malfunctioning or being operated incorrectly, leading to compromised user experiences and inefficient transport requests.
Innovation Solution
A monitoring system using cameras and an interaction analyzer to capture passenger interactions with control panels, analyze their behavior, detect failures, and invoke predefined actions to address these issues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If passenger-operated control panels are used for placing transport requests, then ease of operation is improved, but reliability deteriorates due to malfunction or damage of the apparatus
Solution Approach 1:
The patent introduces an interaction analyzer as an intermediary component that monitors passenger interactions with the control panel through camera images. This mediator detects whether the control panel is functioning correctly by analyzing passenger behavior patterns, thereby monitoring reliability without interfering with the ease of operation of the control panel itself.
2Ease of operation
If control panel apparatuses are installed in landings for placing transport calls, then ease of operation is improved, but device complexity increases due to need for monitoring systems
Solution Approach 1:
The interaction analyzer serves multiple functions: it monitors passenger interactions with control panels, detects failures in control panel operation, and can identify when transport requests are not properly placed. This multi-functionality reduces the need for separate monitoring systems, thereby limiting the increase in device complexity while maintaining ease of operation.
3Reliability
If interaction analysis is performed using camera images, then reliability of failure detection is improved, but loss of time increases due to image processing requirements
Solution Approach 1:
The system continuously captures and pre-processes camera images in real-time as passengers interact with control panels. By performing preliminary analysis on the captured images, the system prepares detection data in advance, enabling rapid failure detection without significant time loss when actual failures occur.
