Automated Fault Reporting for Passenger Transport Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for reporting fault states in passenger transport systems, such as elevators and escalators, are inefficient and often result in incomplete or poorly formatted reports, making it difficult for manufacturers to identify and address recurring issues, as technicians face significant time and language barriers in documenting and evaluating component malfunctions.
Innovation Solution
A machine-supported method and device for reporting fault states, involving a reporting device that acquires and transmits identity and fault information to an analysis device, which selects possible causes of faults and informs a monitoring device when frequency thresholds are exceeded, enabling standardized reporting and analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If technicians manually document fault states using traditional reporting methods, then they can identify component malfunctions, but the reporting process consumes significant time and produces inconsistent, difficult-to-evaluate reports
Solution Approach 1:
The patent replaces manual mechanical documentation processes with automated electronic data acquisition and transmission systems. Reporting devices automatically capture fault information from components and transmit it to analysis devices, eliminating the need for technicians to manually write and format reports, thus reducing reporting time while improving documentation consistency and quality
Solution Approach 2:
The patent introduces intermediate reporting devices and analysis devices that act as mediators between the faulty components and the technicians. These devices automatically acquire fault information, process it through standardized formats, and present it in an easily evaluable form, reducing both the time required and improving the quality of fault documentation
2Reliability
If technicians independently determine component properties based on operating instructions, then they can ensure component compliance, but the process becomes arduous and time-consuming
Solution Approach 1:
The patent enables components to self-report their status and properties through integrated sensors and communication interfaces. Components automatically provide data about their operational state, eliminating the need for technicians to manually verify each property against operating instructions, thus maintaining reliability while significantly improving ease of operation
Solution Approach 2:
The patent replaces manual verification processes with automated electronic data exchange between components, reporting devices, and analysis devices. The system automatically compares component properties against required specifications, ensuring compliance without requiring technicians to arduously determine each property manually
3Loss of information
If technicians generate detailed reports on fault states, then manufacturers can identify system-related issues, but the reports are frequently difficult to evaluate and generate
Solution Approach 1:
The patent transforms unstructured fault descriptions into standardized structured data with defined parameters and formats. The analysis device automatically processes raw fault information and presents it in a standardized format that is easy to evaluate, maintaining complete fault information while reducing the complexity of report generation and analysis
Solution Approach 2:
The patent divides the reporting system into distinct functional modules: reporting devices for data acquisition, communication interfaces for data transmission, and analysis devices for data processing. This segmentation allows each component to focus on a specific task, reducing overall system complexity while ensuring complete and evaluable fault information
4Adaptability or versatility
If multiple different reporting formats are used by technicians, then various fault conditions can be documented, but the diversity makes evaluation extremely difficult
Solution Approach 1:
The patent implements a universal standardized reporting format that can accommodate various types of fault conditions while maintaining consistency. The analysis device is designed to process multiple types of fault information through a single standardized interface, preserving the versatility needed to document different faults while eliminating the evaluability problems caused by format diversity
Data Source
AI summary
A method for reporting component fault states of a passenger transport system includes the steps: detecting identity information and/or fault state information of a component being examined using a reporting device; automatically transmitting the detected information to an analysis device; automatically selecting a selection of possible causes of the fault from a list based on the identity information and/or the fault information and transmitting corresponding selection information to the reporting device; automatically outputting the selection information from the reporting device and receiving sub-selection information describing a sub-selection selected by a reporter from the selection of possible causes of the fault; and automatically transmitting the sub-selection information to the analysis device. Possible causes of the fault states are reported and collected in a simple and standardized manner. A monitoring device is informed of possible causes of faults that arise frequently so that components can be further developed in a targeted manner.
