Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing passenger transport installations, such as elevators, escalators, and moving walkways, face challenges in configuring security-related parameters individually while minimizing the risk of incorrect or unintended configuration, which can lead to safety hazards and non-compliance with local regulations.
Innovation Solution
A method that utilizes sensors already present in the passenger transport installations to detect a unique key signal pattern, temporarily switching the control into a configuration mode, allowing for the reconfiguration of security-related parameters without the need for additional hardware interfaces, using either statically premagnetized test pieces or dynamically generated magnetic or optical patterns to ensure secure and accurate parameter setting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If additional hardware interfaces are added for configuration, then configuration capability is improved, but device complexity increases
Solution Approach 1:
The patent makes existing sensors serve a dual function: their primary function for detecting operating parameters during normal operation, and a secondary function for detecting configuration signals during configuration mode. This eliminates the need for separate configuration hardware interfaces while maintaining configuration capability.
Solution Approach 2:
The control unit operates in multiple modes (normal operation mode and configuration mode) using the same hardware components. The same sensors and communication interfaces are utilized for both operational monitoring and configuration tasks, thereby avoiding additional hardware complexity.
2Ease of operation
If configuration is made easier through accessible interfaces, then ease of operation is improved, but security against incorrect configuration deteriorates
Solution Approach 1:
The system requires preliminary authentication before allowing configuration. A specific configuration signal with a predefined pattern must be detected by the sensors before the control unit enters configuration mode, preventing unauthorized or accidental configuration attempts.
Solution Approach 2:
The control unit provides feedback by monitoring whether detected sensor signals match the expected configuration signal pattern. Only when the pattern is correctly recognized does the system transition to configuration mode, ensuring secure access while maintaining ease of legitimate configuration.
3Adaptability or versatility
If region-specific configuration is enabled, then adaptability to local regulations is improved, but risk of incorrect parameter entry increases
Solution Approach 1:
The patent employs a predefined configuration signal pattern that must be detected before configuration parameters can be entered. This preliminary authentication step ensures that only authorized configuration activities can modify security-related parameters, reducing the risk of incorrect entry while enabling region-specific adaptations.

AI summary
A method for configuring security related configuration parameters is used in a passenger transport installation that includes at least one sensor exchanging sensor signals with a control. The sensor detects operating parameters within the passenger transport installation and emits corresponding sensor signals. The control controls security related functions of the passenger transport installation taking into account the sensor signals and the configuration parameters. The method includes: comparing the sensor signals with a predefined key signal pattern; operating the control temporarily in a configuration mode exclusively if the compared sensor signals correspond to the key signal pattern; and configuring the security related configuration parameters during the configuration mode. An installation-specific sensor (e.g. optical sensor or magnetic field sensor) functions as an interface to put the control into configuration mode in a targeted manner, e.g. by a test piece with a barcode maintained in the field of view of the optical sensor.
