Solution Overview
Problem
Current escalator and passway systems lack efficient methods for analyzing dimensions and tolerances of components, making system analysis laborious, especially during test runs or when errors occur, as these considerations are typically independent and uncorrelated.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If dimensions and tolerances of system components are considered individually and independently, then the measurement process is simple, but system analysis becomes laborious and inefficient
Solution Approach 1:
The patent combines multiple independent measurement systems into a unified reference system that simultaneously measures dimensions and tolerances of multiple components. The reference system integrates coordinate systems, measurement devices, and evaluation units into a single coordinated structure that correlates measurements across different components, thereby improving system analysis efficiency while maintaining manageable complexity through standardized integration.
Solution Approach 2:
The reference system is designed with multi-functionality to handle various measurement tasks across different components. It provides a universal coordinate system that can reference multiple components simultaneously, and the evaluation unit can assess different types of deviations (dimensional and positional) using the same integrated system, making the measurement process more efficient without requiring separate specialized systems for each component.
2Reliability
If a reference system is implemented to correlate dimensions and tolerances of multiple components, then system analysis and fault detection are facilitated, but the complexity of the measuring system increases
Solution Approach 1:
The reference system is segmented into distinct functional modules: coordinate systems for each component, measurement devices for capturing dimensional data, and an evaluation unit for correlating and analyzing the data. This modular segmentation allows the system to achieve high reliability through comprehensive correlation while managing complexity by organizing functions into separate, standardized modules that can be independently maintained and calibrated.
Solution Approach 2:
The patent introduces a central reference system as an intermediary that mediates between multiple components and their individual measurements. This reference system acts as a mediator that correlates measurements from different components through unified coordinate systems and tolerance specifications, enabling reliable system-wide analysis while reducing the complexity that would arise from direct pairwise comparisons of all components.
3Loss of time
If individual component measurements are performed without correlation, then the measurement process is straightforward, but fault analysis during test runs becomes laborious
Solution Approach 1:
The reference system performs preliminary correlation of dimensions and tolerances for all components before actual operation or test runs. By establishing the relationships and tolerance boundaries in advance through the integrated measurement system, the system is prepared for rapid fault analysis during operation, reducing the time required to identify and diagnose issues without requiring complex real-time calculations during critical operations.
