Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The manual inspection and logging of elevator components in elevator shafts is labor-intensive and risky, especially with increasing complexity and safety standards, and the need to access components in difficult locations.
Innovation Solution
Implementing machine-readable markers on elevator components, such as RFID tags or barcodes, that can be read by a marker reading device attached to a movable elevator element, allowing for automated collection and comparison of component-specific information with nominal specifications, and generating reports on conformity and differences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual inspection and logging of elevator components is performed, then component information can be recorded, but the process requires considerable time and labor
Solution Approach 1:
The patent replaces the manual mechanical inspection process with an automated optical scanning system. A marker reading device mounted on the elevator car automatically reads machine-readable markers (barcodes, RFID tags) on components as the car moves through the shaft, eliminating manual data collection while maintaining accurate component information recording
Solution Approach 2:
The patent creates digital copies of component information through machine-readable markers that contain encoded data about each component. Instead of manually transcribing component details, the system reads and stores digital replicas of component identifiers and specifications, significantly reducing inspection time while preserving data accuracy
2Loss of information
If manual inspection of all elevator components is performed, then complete component documentation is achieved, but the work requires considerable effort and resources
Solution Approach 1:
The system replaces labor-intensive manual inspection with automated optical scanning and data processing. The marker reading device continuously scans markers on components while the elevator car moves, automatically capturing complete component documentation without requiring inspector effort for each individual component
Solution Approach 2:
The inspection process operates continuously as the elevator car moves through the shaft, with the marker reading device constantly scanning components in its path. This eliminates the stop-start nature of manual inspection and maintains continuous data collection, improving overall inspection efficiency while ensuring complete documentation
3Measurement precision
If inspectors access components in difficult-to-reach areas of the elevator shaft, then complete inspection coverage is achieved, but safety risks increase
Solution Approach 1:
The patent introduces the marker reading device as an intermediary between the inspector and hard-to-reach components. The device is mounted on the elevator car and automatically reads markers on components in difficult locations without requiring the inspector to physically access those areas, maintaining complete inspection coverage while eliminating safety risks
Solution Approach 2:
The inspection system performs self-service by automatically scanning and recording component information without human intervention in dangerous areas. The elevator car itself serves as the mounting platform for the scanning device, enabling the system to inspect components in hard-to-reach locations independently without exposing personnel to safety risks

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This method enables rapid, safe, and efficient inspection and logging of elevator components, reducing human error and improving safety by automating the process, even for components in hard-to-reach areas, and ensuring compliance with safety standards.
Implementation Method 1
machine-readable markers on which or by means of which component-specific information is stored, which can be read out by means of a marker reading device
Data Source
AI summary
A method determines information relating to elevator components received in an elevator shaft, the elevator components each being provided with a machine-readable marker on which component-specific information is stored, which information is read out by a marker reading device. In the method, a movable elevator element on which the marker reading device is arranged is moved through the elevator shaft and the component-specific information is read out from the markers. The markers can be, for example, markers that can be read out electromagnetically and in a contactless manner, such as RFID tags. The method also includes a comparison of the read-out component-specific information with nominal specifications, and the compiling of a report indicating instances of conformity and/or differences between the read-out component-specific information and the nominal specifications.
