Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a centralized service center is used to monitor and diagnose multiple elevator systems, then comprehensive monitoring coverage is achieved, but system complexity and susceptibility to faults increase
Solution Approach 1:
The patent divides the centralized monitoring function into distributed components. Each elevator system has its own control device with memory and processing capabilities that can independently store and analyze operational data. This segmentation eliminates the single point of failure in centralized systems while maintaining comprehensive monitoring across multiple elevators.
Solution Approach 2:
The patent introduces an intermediary communication interface that enables bidirectional data exchange between elevator control devices and external service centers via standard communication protocols. This intermediary layer allows remote access to stored diagnostic data without requiring a complex centralized monitoring infrastructure, reducing system complexity while maintaining monitoring capabilities.
2Reliability
If a centralized service center with multiple redundancies is implemented, then fault avoidance is improved, but system complexity and cost increase
Solution Approach 1:
The patent implements beforehand cushioning by equipping each elevator control device with local memory capacity to store operational and diagnostic data. This local data buffering capability ensures that monitoring and diagnosis can continue even if communication with external systems fails, providing fault resistance without requiring complex redundant centralized infrastructure.
Solution Approach 2:
The control device is designed with integrated signal processing capabilities that enable it to autonomously analyze stored data and generate diagnostic information. This self-service approach eliminates the need for complex centralized processing systems while maintaining reliable fault detection and diagnosis across multiple elevator installations.
3Measurement precision
If extensive data collection and analysis is performed at a service center, then comprehensive diagnostic capability is achieved, but effort and time requirements increase
Solution Approach 1:
The patent implements preliminary action by continuously storing operational data, fault information, and event logs in the control device's memory during normal elevator operation. This pre-collected data is readily available for immediate analysis when diagnostic needs arise, eliminating the time required for data collection during fault conditions while maintaining comprehensive diagnostic capability.
Solution Approach 2:
The patent replaces manual data collection and analysis processes with automated signal processing capabilities integrated into the control device. The system automatically stores, organizes, and makes accessible diagnostic data through standardized communication interfaces, substituting manual effort with automated electronic data management to reduce diagnosis time while maintaining precision.
4Ease of operation
If remote communication capabilities are added to elevator control devices, then remote diagnosis capability is improved, but device complexity increases
Solution Approach 1:
The patent implements universality by designing the communication interface to support multiple communication protocols and data exchange formats. This multi-functional interface can communicate with various types of external devices (service centers, portable diagnostic tools, mobile devices) using standard protocols, providing broad remote access capability without requiring separate specialized interfaces for each communication scenario.

AI summary
The invention relates to a method for remote diagnostics of an elevator system (10) comprising at least one car (16) which can be moved in a shaft (12) by means of a drive unit (22, 24), and an elevator control device (30) comprising at least one signal processing unit (60) and at least one storage element (62), wherein the elevator control device (30) controls the operation of the elevator system (10).To further develop the method in such a way that it is more cost-effective and less susceptible to interference, it is proposed that availability, fault, and/or event data of the elevator system (10) be recorded, stored in the memory element (62), and analyzed using the signal processing unit (60); that the location of the elevator system (10), together with status information dependent on the result of the analysis of the stored data, be transmitted via the internet (78) to at least one data receiving device (81, 82, 83) and displayed on its monitor (85) on a map that can be updated via the internet (78); and that the stored data be made accessible to specific target groups via the internet (78). Furthermore, an elevator system (10) for carrying out the method is proposed.
