Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for managing elevator data are inaccurate, leading to unnoticed deviations from planned structures during installation, causing issues such as misaligned components and potential safety hazards, particularly in new or modernized elevators where incomplete data about the elevator hoistway or building structures can result in delays and modifications.
Innovation Solution
A method involving the use of scanning apparatuses to collect and compare data on elevator structures, forming a three-dimensional model to accurately determine the shape and position of elevator components, linking this data to a database for reliable identification and management, allowing for real-time detection and rectification of deviations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual measuring and spot checks are used to verify elevator structures, then the installation process is simple and quick, but measurement precision and reliability are insufficient, allowing deviations to go unnoticed
Solution Approach 1:
The patent replaces manual mechanical measuring methods with automated scanning apparatus that uses optical or laser-based technologies to collect three-dimensional data about elevator structures. This substitution dramatically improves measurement precision and reliability while reducing human error and the need for complex manual verification procedures.
Solution Approach 2:
The patent creates digital copies (three-dimensional models) of the actual elevator structures by scanning them. These digital models serve as accurate representations that can be stored, analyzed, and compared without requiring physical re-measurement, thereby improving data accuracy while simplifying the verification process.
2Reliability
If comprehensive verifying measurements are performed to detect all deviations from plan, then data accuracy improves, but the installation process becomes more time-consuming and complex
Solution Approach 1:
The patent performs scanning and data collection activities during the installation process itself, rather than as separate preliminary or follow-up steps. By integrating measurement into the installation workflow, the system achieves comprehensive verification without adding significant time to the overall process.
Solution Approach 2:
The scanning apparatus continuously collects data about elevator structures as installation progresses, maintaining an up-to-date digital model throughout the process. This continuous data collection ensures reliability without requiring multiple discrete measurement campaigns that would consume time.
3Loss of information
If data about elevator structures is collected and stored for future reference, then information availability improves, but data accuracy and reliability remain insufficient due to manual collection methods
Solution Approach 1:
The patent replaces inaccurate manual measurement and data recording methods with automated scanning apparatus that captures precise three-dimensional coordinates and geometric information. This substitution ensures both completeness and high accuracy of the stored data, eliminating the trade-off between information availability and precision.
