Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual configuration with cable-connected control units and mechanical buttons is used, then position data can be recorded and stored, but the configuration process becomes cumbersome, time-consuming, and requires considerable training
Solution Approach 1:
The patent replaces mechanical buttons and cable-connected control units with a touch-sensitive display interface on a mobile data processing unit. This substitution eliminates the need for physical cable connections and mechanical input devices, providing a more intuitive and easier-to-operate interface while maintaining position data recording accuracy through digital input methods.
Solution Approach 2:
The mobile data processing unit serves as an intermediary between the operator and the elevator system configuration. It wirelessly interfaces with the elevator control system, providing a portable and flexible configuration tool that simplifies operator interaction while ensuring accurate position data recording through its processing capabilities.
2Reliability
If traditional configuration tools with numerical displays are used, then position data can be entered, but the handling becomes awkward and error-prone
Solution Approach 1:
The patent replaces numerical displays with graphical user interfaces on touch-sensitive screens. This allows for more intuitive interaction through visual representations of elevator positions and floor plans, reducing handling errors while improving operational convenience through direct touch input and graphical manipulation of configuration data.
3Measurement precision
If position measuring devices are used to generate position data, then car stopping positions can be identified, but hysteresis effects and imprecise data make unambiguous position data generation difficult
Solution Approach 1:
The mobile data processing unit implements feedback mechanisms that allow operators to review, verify, and adjust position data before final storage. The system can display measured positions alongside reference floor positions, enabling operators to detect and correct hysteresis effects or imprecise measurements, thereby improving both precision and consistency of the final position data.
