Solution Overview
Problem
The existing methods for modernizing elevator control systems require significant maintenance effort, as they necessitate physical replacement of memory cards and individual servicing of destination call terminals, leading to high personnel deployment and material costs.
Innovation Solution
A method utilizing a mobile control data storage element with a near-field radio link to wirelessly update control data packets directly to terminals, eliminating the need for physical card changes and reducing maintenance effort by enabling remote software updates via a wireless near-field radio link.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If memory cards are permanently connected to central control units for ongoing operation, then reliable access to control data is achieved, but maintenance effort increases due to physical card replacement requirements
Solution Approach 1:
The patent replaces the mechanical system of physical memory card insertion and removal with a wireless data transmission system. Control data is transferred via radio frequency communication between a portable transmitter and the control unit, eliminating the need for physical card handling while maintaining reliable data access during operation.
Solution Approach 2:
The patent uses a portable wireless transmitter that contains a copy of the control data packet. This allows the control data to be transmitted wirelessly to the control unit without requiring physical memory cards to be inserted or removed, thereby maintaining data reliability while reducing maintenance effort.
2Adaptability or versatility
If destination call terminals are serviced individually with physical card replacement, then control functions are updated, but maintenance costs increase due to high personnel deployment
Solution Approach 1:
The portable wireless transmitter serves multiple terminals sequentially without requiring physical card changes at each location. A single transmitter can update control functions across multiple destination call terminals by wirelessly transmitting the control data packet to each terminal in turn, significantly improving maintenance efficiency while maintaining adaptability for different terminals.
Solution Approach 2:
The patent replaces the mechanical process of physically replacing cards at each terminal with wireless data transmission. This eliminates the need for personnel to open terminal housings and physically swap cards, thereby updating control functions across multiple terminals efficiently without increasing maintenance costs.
3Reliability
If physical memory cards are used for control data storage, then data is reliably stored, but material costs increase due to continuous card production
Solution Approach 1:
The patent uses a portable transmitter that contains a copy of the control data packet in digital form. This eliminates the need to produce physical memory cards for each update, as the same digital data can be transmitted repeatedly without consuming additional physical materials, thereby reducing material costs while maintaining reliable data storage capability.
Solution Approach 2:
The patent eliminates the need to discard physical memory cards after use. Instead, the control data packet is stored digitally in the portable transmitter and can be transmitted indefinitely without degradation or consumption of physical materials, recovering the value of the control data for repeated use across multiple terminals and updates.

AI summary
In a method for modernizing the control system of an elevator (10) with at least one terminal (20, 25), the terminal (20, 25) is updated with a control data package stored on a mobile control data storage element (30) for the purpose of modernizing the control functions of the elevator (10). The control data package is transmitted from the mobile control data storage element (30) to the terminal (20, 25) via a near-field radio link generated within a predetermined distance (R) between the mobile control data storage element (30) and the terminal (20, 25), and the control data package is stored in a storage unit (21, 26) of the terminal (20, 25).
