Elevator Device Placement Guidance Using Camera and Laser Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for arranging elevator devices, such as those involving a reference wire material, are limited to devices in a pit and cannot be applied to devices not provided in a pit.
Innovation Solution
An assistance system that includes an image capturing apparatus to capture images of device positions and a guidance system to provide guidance for arrangement based on these images, allowing for the arrangement of various elevator devices regardless of their location.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a reference wire material lowered vertically downward in a hoistway is used for positioning, then the positioning method is simple and can be implemented, but the method cannot be applied to arrangement of devices not provided in a pit
Solution Approach 1:
The patent replaces the mechanical reference wire positioning system with an optical system using a visible laser apparatus. The laser beam provides visual guidance for positioning devices in various locations (pit, machine room, etc.) without requiring physical wire installation, thereby expanding applicability while maintaining implementation simplicity
Solution Approach 2:
The visible laser apparatus serves multiple positioning functions across different device locations (buffer footing in pit, traction machine in machine room, etc.). A single laser system can guide positioning for various devices throughout the elevator shaft and associated spaces, eliminating the need for location-specific positioning methods
2Ease of operation
If visual guidance and audio notifications are provided for arrangement work, then workability and accuracy are improved, but the system complexity increases
Solution Approach 1:
The patent introduces a camera and display unit as intermediary components between the laser positioning system and the worker. The camera captures real-time images of the device position relative to the laser guide, and the display unit presents this visual feedback to the worker, simplifying the positioning operation while adding minimal system complexity
Solution Approach 2:
The system implements visual feedback by capturing images with a camera and displaying them on a display unit. This allows workers to see their positioning progress in real-time and make adjustments accordingly, improving ease of operation through immediate visual confirmation of device placement accuracy

AI summary
To provide an assistance system that can be applied to arrangement work on a wide variety of devices of an elevator. An assistance system includes an image capturing apparatus and a guidance system. The image capturing apparatus captures, in arrangement work, an image of an area including a position of a target arrangement corresponding to each of one or more devices of an elevator. The arrangement work is work involving arranging each of the devices in a corresponding target arrangement. The guidance system guides arrangement of each of the devices in the corresponding target arrangement based on the image captured by the image capturing apparatus.
