Portable Elevator Inspection Control Station
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing elevator control systems require multiple inspection control stations, leading to inefficiencies and increased time and effort for technicians performing maintenance and inspection tasks, as they need to navigate multiple locations within the elevator system.
Innovation Solution
A centralized inspection control station that can be accessed and used remotely via wireless communication with the elevator control device, allowing a single technician to perform inspections and maintenance efficiently by moving the control station within the system, while ensuring compliance with safety standards like EN 81-20(2014).
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple inspection control stations are installed at different locations (pit, car roof, inside car), then safety requirements are met and inspection coverage is improved, but device complexity and time/effort for technicians increase
Solution Approach 1:
A single inspection control station is designed to perform multiple functions and be used at multiple locations. The control station can be temporarily connected to different safety points (pit, car roof, inside car) sequentially, eliminating the need for permanently installing multiple control stations while maintaining comprehensive inspection coverage.
Solution Approach 2:
The inspection control station is designed to be dynamically relocatable rather than statically fixed. The control station can be moved and reconnected to different positions within the elevator system, allowing a single dynamic control station to replace multiple static control stations.
2Reliability
If multiple inspection control stations are installed at different locations, then inspection coverage is improved, but time and effort for technicians performing maintenance increases
Solution Approach 1:
The single control station can serve multiple inspection locations sequentially. The technician moves the same control station from one location to another, reducing the time and effort associated with switching between multiple fixed control stations and minimizing travel time between inspection points.
3Reliability
If inspection control stations are permanently installed at multiple locations, then safety monitoring is improved, but wiring complexity and installation effort increase
Solution Approach 1:
The control station is extracted from the fixed installation and made portable. Instead of permanently installing control stations at multiple locations with complex wiring, a single control station is removed from fixed mounting and can be temporarily connected to different positions, significantly reducing wiring complexity.
Solution Approach 2:
The control station transitions from a static permanently installed configuration to a dynamic portable configuration. This allows the control station to be relocated and reconnected as needed, eliminating the need for complex permanent wiring infrastructure at multiple locations.
