Elevator Control Component ID Verification System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Elevator manufacturers face the issue of pirate products being used in elevator controls, which affects business turnover, reliability, and safety, as well as the image of the manufacturer, due to the introduction of low-quality components.
Innovation Solution
A system that includes an authorization section in the elevator control to verify the IDs of essential electronic components against a reference list, preventing operation if mismatched or unauthorized components are detected, and an updating mechanism to ensure only approved parts are used by connecting to a service tool or central database for ID management and updates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If pirate products are used to replace essential components in elevator control, then cost is reduced, but reliability and safety deteriorate
Solution Approach 1:
The patent applies preliminary action by equipping essential electronic components with unique identification means (ID tags, authorization chips, or memory storage) before they are installed in the elevator control system. The control unit is pre-programmed with reference identification data for authorized components. This preliminary identification setup enables the system to automatically verify component authenticity during operation, preventing the use of pirate products while maintaining reliability without requiring costly manual verification processes.
2Reliability
If authorization verification system is implemented, then reliability is improved, but device complexity increases
Solution Approach 1:
The patent implements self-service by designing an authorization system where the elevator control unit automatically performs verification of component authenticity without requiring external intervention. The control unit reads identification data from components, compares it against stored reference data, and autonomously determines whether to permit operation. This self-verification mechanism enhances safety while minimizing added complexity, as the system handles the entire authorization process internally without requiring additional manual checking procedures or complex external verification infrastructure.

AI summary
The invention refers to a system (10) and to a method to prevent the use of pirate products in an elevator control, the system comprising at least one elevator control (12), an updating means (17, 18) and a connection (14, 16, 17) between the elevator control and said updating means, the elevator control comprises essential electronic components (20, 22, 24, 26, 28) provided with their own ID means (30, 32, 34, 36), and an authorization section, which is configured to read the IDs of the essential electronic components, comprises a reference list with allowed IDs, a comparator and a switching logic configured to issue an authorization signal for the elevator control to start or prevent operation of the elevator control depending on the comparison result of the comparator, whereby the connection between the elevator control and said updating means is configured to initiate the elevator control to update the IDs of the essential electronic components in the elevator control.
