Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If manual start-stop operations are used for escalators and moving walks, then operational control can be performed, but it is time-consuming and labor-intensive
Solution Approach 1:
The control apparatus enables the escalator system to automatically determine and execute start-stop operations based on passenger detection signals. The system self-monitors passenger presence through detectors and autonomously controls motor activation without requiring manual intervention, thereby eliminating time loss associated with manual operations.
2Reliability
If remote video surveillance is used to monitor loading status, then operational decisions can be made, but installation and maintenance costs are high and reliability is poor
Solution Approach 1:
The invention extracts the essential monitoring function from complex video surveillance systems and implements a dedicated passenger detection device that directly interfaces with the control apparatus. This specialized detector is positioned to specifically detect passenger presence at the entrance, providing reliable signals for operational control without the complexity and cost of general-purpose video surveillance.
Solution Approach 2:
The control apparatus serves as an intermediary between the passenger detection device and the motor control system. It receives detection signals, processes them according to control logic, and generates appropriate control commands, thereby simplifying the overall system architecture while maintaining high reliability in operational monitoring.
3Productivity
If remote video surveillance is used for start-stop operations, then operational efficiency can be improved, but installation and maintenance costs are high
Solution Approach 1:
The invention employs a cost-effective passenger detection device instead of expensive video surveillance infrastructure. The detection device uses simpler, more economical sensors and processing components that can be easily installed and maintained, achieving the same productivity improvement in start-stop operations at a fraction of the cost.
4Reliability
If existing escalators are upgraded with video surveillance, then operational monitoring can be achieved, but reconstruction cost is high
Solution Approach 1:
The control apparatus is designed to be universally applicable to existing escalator and moving walk systems. It interfaces with standard motor control mechanisms and can work with various types of passenger detection devices, allowing existing infrastructure to be upgraded with reliable operational monitoring without expensive custom reconstruction.
