Elevator Car Device Mounting With Through-Wall Power Sleeve
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Installing digital or electric devices in existing elevators is challenging due to the difficulty in providing electrification from outside to inside the elevator car without requiring multiple assemblers.
Innovation Solution
An installation tool comprising a tube, a plate, a detachable sleeve, and a counter plate is used to facilitate easy installation by extending electrification from outside to inside the elevator car, allowing a single assembler to attach the device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional installation methods are used for existing elevators, then electrification can be provided, but multiple assemblers are required and installation is difficult
Solution Approach 1:
The installation tool is divided into separate components: a plate for external mounting, a detachable sleeve for passing through the wall, and a counter plate for internal mounting. This segmentation allows each component to be installed independently through separate access points, eliminating the need for multiple assemblers to work simultaneously through one hole.
Solution Approach 2:
The detachable sleeve acts as an intermediary element that connects the external plate to the internal counter plate through the elevator wall. It carries the electrification conduit through the wall thickness, enabling electrical connection while simplifying the installation process to require only single-sided access.
2Productivity
If electrification is provided through the wall, then electric devices can be installed, but the process requires multiple assemblers and is time-consuming
Solution Approach 1:
The plate is pre-mounted on the external side of the elevator wall before the through-wall operation. This preliminary action prepares the entry point for the detachable sleeve, allowing the electrification conduit to be threaded through efficiently without requiring coordinated multi-assembler work, thereby reducing installation time.

AI summary
There is provided a method for installing an electric device to an elevator car. An installation tool includes a tube configured to carry electrification for the electric device; a plate attached at an end part of the tube, the plate having a hole; a detachable sleeve configured to carry the electrification through the hole of the plate, and a counter plate having a hole and configured to receive the electric device. The method comprises placing the installation tool outside of a wall of the elevator car such that the plate is configured to be placed next to outside wall of the elevator car, the tube is configured to extend along the outside wall of the elevator car; and the detachable sleeve is configured to pass through a hole on the wall of the elevator car; attaching the counter plate inside the elevator car to the wall of the elevator car and to the plate outside of the elevator car such that the detachable sleeve is configured to pass the hole of the plate, the hole of the wall and the hole of the counter plate. The method may comprise detaching the sleeve; and connecting the electric device inside the elevator car to the electrification and attaching the electric device to the counter plate.
