Solution Overview

Problem

Existing elevator shaft mounting systems risk damage due to the carrier component not being consistently supported by the upper support roller during displacement, leading to potential swinging and collision with the shaft walls.

Innovation Solution

A mounting system with a diagonal pull support means and a compensating element to ensure the carrier component remains in contact with the support wall, preventing tilting and collision by introducing a horizontal component to the retaining force and adjusting distances to maintain equilibrium.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the support means extends vertically downward, then the mounting device can be displaced in the elevator shaft, but the carrier component is not consistently supported by the upper support roller, leading to swinging and potential collision with shaft walls

Engineering Contradiction:

Improveconsistent support of carrier componentVSAvoidswinging and collision risk

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The support means is designed with an asymmetric diagonal configuration rather than a symmetric vertical arrangement. The support means extends from the displacement component at an angle of 10-45 degrees relative to the vertical, creating an asymmetric force distribution that generates a horizontal retaining force component. This asymmetric geometry ensures the carrier component is consistently retained against the support wall during displacement, preventing swinging and collision while maintaining reliable support throughout the operation.

Inventive Principle:

Principle #4Asymmetry

2Reliability

If the support means has a diagonal pull in the direction of the support wall, then the carrier component is reliably retained against the support wall, but the support means extends at an angle rather than vertically

Engineering Contradiction:

Improveretention of carrier component on support wallVSAvoidvertical alignment of support means

Core Design Contradiction:

ReliabilityVSShape

Solution Approach 1:

The support means deliberately adopts an asymmetric diagonal shape instead of a vertical configuration. By extending at an angle of 10-45 degrees from the vertical, the support means creates a geometric asymmetry that generates the necessary horizontal force component for reliable retention while accepting the compromised vertical alignment as a necessary design trade-off.

Inventive Principle:

Principle #4Asymmetry

3Productivity

If the mounting device is displaced in the elevator shaft, then installation operations can be performed, but the carrier component may tilt about the upper support roller, causing the lower support rollers to lift off and potentially strike shaft walls

Engineering Contradiction:

Improvedisplacement capabilityVSAvoidtilting of carrier component

Core Design Contradiction:

ProductivityVSStability of the object's composition

Solution Approach 1:

The diagonal configuration of the support means creates an asymmetric force distribution that produces a horizontal retaining force component. This asymmetric force application point and direction counteracts the tilting moment that occurs during displacement, preventing the carrier component from rotating about the upper support roller and ensuring lower support rollers remain in contact with the support wall throughout the displacement operation.

Inventive Principle:

Principle #4Asymmetry

AI summary

A mounting system has a mounting device with a carrier component and a mechatronic installation component, a displacement component arranged above the mounting device in an elevator shaft and a support member connected between the carrier component and the displacement component. The displacement component displaces the mounting device in the shaft using the support member, wherein the carrier component is supported by an upper support roller on a support wall of the shaft during the displacement in the shaft. The support member generates a diagonal pull perpendicular to the support wall surface. The mounting system also has a compensating element that counteracts a tilting of the carrier component about the upper supporting roller perpendicular to the support wall during the displacement in the shaft.
