Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing installation devices for elevator shafts are complex to construct and position, requiring multiple carriers and deflection mechanisms, which increases weight and complicates the installation process, especially in deep shafts where the inclination of the carriers becomes less effective.
Innovation Solution
A simplified installation device with a single carrier that is adjustable, allowing the support plane of the receiving device to be aligned horizontally independently of the carrier's inclination, eliminating the need for deflection mechanisms and using a multi-part arm for easy angle adjustment, enabling straightforward positioning and reduced weight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple carriers and deflection mechanisms are used to support installation material in deep elevator shafts, then the installation device can maintain support functionality, but the device complexity and weight increase significantly
Solution Approach 1:
The patent removes the deflection roller and its associated mounting structure from the system. By directly supporting the suspension means at the first carrier end, the complex deflection mechanism is extracted and eliminated, reducing device complexity while maintaining the essential support function through the simplified direct connection approach
Solution Approach 2:
The patent divides the support function into two independent elements: the carrier providing structural support and the support element providing adjustable positioning. This segmentation allows each component to be optimized independently, reducing overall complexity while maintaining reliability through functional specialization
2Reliability
If multiple carriers and deflection mechanisms are used to support installation material in deep elevator shafts, then the installation device can maintain support functionality, but the weight of the installation device increases
Solution Approach 1:
The patent extracts and removes the deflection roller and its mounting structure from the system. This elimination of unnecessary components directly reduces the weight of the installation device while the essential support functionality is maintained through the simplified direct support configuration at the carrier end
Solution Approach 2:
The patent merges the support function into the carrier structure itself by providing a support element directly at the first carrier end. This consolidation eliminates separate deflection mechanisms and reduces overall device weight while maintaining the necessary support capability through integrated design
3Length of stationary object
If the carrier is inclined upward relative to the horizontal to reach deep shafts, then the carrier can span the distance, but the support plane for the displacement device becomes misaligned and requires deflection mechanisms
Solution Approach 1:
The patent introduces an adjustable support element that can be positioned at different locations along the carrier. This dynamic adjustment capability allows the support plane to be optimized for horizontal alignment regardless of the carrier's inclination angle, eliminating the need for fixed deflection mechanisms and improving ease of operation
Solution Approach 2:
The patent separates the carrier's structural support function from the displacement device support function by providing a dedicated support element. This segmentation allows the carrier to maintain its inclined configuration for spanning deep shafts while the support element independently provides the necessary horizontal alignment for the displacement device

Function Achieved in This Case
The solution allows for easy and cost-effective installation in deep elevator shafts by reducing the complexity of the device, minimizing weight, and facilitating the displacement of installation materials without the need for deflection, thus simplifying the construction and positioning process.
Implementation Method 1
The support element is pivotably arranged on the first carrier end and is designed and arranged such that, in an installation position of the installation device, the carrier can be supported via the support element in the region of a door opening

AI summary
An installation device for use in an elevator shaft includes a carrier that extends in a carrier direction, the carrier having a first carrier end and a second carrier end, a support element that is pivotably arranged on the first carrier end and a receiving device for receiving a displacement device by which installation material can be displaced in the elevator shaft. The receiving device is supported on the carrier via an adjustable support device such that an angle between a support plane, in which plane a support surface of the receiving device extends, and the carrier direction of the carrier can be changed.
