Solution Overview

Problem

The existing methods for installing elevator guide rails are labor-intensive and lack automation, requiring manual alignment and installation, which can be inefficient and prone to errors, especially in taller elevator shafts.

Innovation Solution

A method and arrangement that automates the installation of guide rails by using a combination of industry robots and alignment tools, allowing for the manual installation of the first section and subsequent automatic alignment and attachment of subsequent sections, utilizing a lifting frame and installation platform with hoists to position and secure guide rail elements with support brackets and bolts.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If manual installation methods are used for guide rails, then installation flexibility is maintained, but labor intensity increases and installation precision decreases

Engineering Contradiction:
Improveautomation of guide rail installationVSAvoidcomplexity of installation system
Core Design Contradiction:
Extent of automationVSDevice complexity

Solution Approach 1:

The guide rail installation system is divided into multiple independent modules: a lifting frame for vertical movement, an installation platform for positioning, alignment tools for precision alignment, and attachment mechanisms for securing rails. Each module can be independently controlled and positioned, enabling automated installation while maintaining manageable system complexity through modular architecture.

Inventive Principle:
Principle #1Segmentation

2Manufacturing precision

If automated installation systems are introduced, then installation precision and efficiency improve, but system complexity and initial cost increase

Engineering Contradiction:
Improvealignment precision of guide railsVSAvoidcomplexity of automated installation system
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

Alignment tools serve as intermediary devices between the installation platform and the guide rails, providing precise measurement and adjustment capabilities. These tools act as mediators that translate automated platform positioning into accurate rail alignment, enabling high precision installation without requiring the entire system to be overly complex.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of operation

If manual labor is used for high-height installations, then equipment requirements are minimized, but safety risks and labor intensity increase

Engineering Contradiction:
Improvesafety of installation operationVSAvoidcomplexity of lifting and positioning equipment
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The installation platform is designed to be movable to different heights along the guide rails using the lifting frame, allowing workers to operate at equipotential positions regardless of installation height. This eliminates the need for workers to manually handle heavy rails at dangerous heights, significantly improving safety while the automated positioning system manages the complexity of vertical movement.

Inventive Principle:
Principle #12Equipotentiality
