Safety Switch Pairing Control for Secure Actuator Association
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing safety switch systems require complex procedures for initial association between the sensor body and actuator, which can lead to reliability issues and potential fraudulent use, especially during the resetting process.
Innovation Solution
A safety switch system with a setting unit, detection unit, and control unit that simplifies the initial association by allowing identification information of the actuator to be acquired and stored when the operation mode is set to a pairing mode, preventing fraudulent use and maintaining reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a complex pairing procedure is used to associate the sensor body and actuator, then the reliability of the safety switch is improved, but the ease of operation deteriorates
Solution Approach 1:
The system performs preliminary actions by automatically detecting when the actuator is held near the sensor body and proactively enters pairing mode, storing the actuator ID without requiring complex user procedures. This preliminary automatic detection and storage resolves the contradiction by maintaining reliability through secure pairing while dramatically simplifying operation.
2Ease of operation
If the sensor body stores identification information of any detected actuator, then the ease of operation is improved, but the reliability deteriorates due to potential fraudulent use
Solution Approach 1:
The system dynamically adjusts its behavior based on operational context: in pairing mode, it stores actuator IDs freely for ease of operation, while in normal operation mode, it strictly verifies stored IDs to prevent fraudulent use. This dynamic switching of operational states resolves the contradiction by providing simplicity when needed while maintaining security when required.
3Reliability
If the safety switch requires complex verification procedures, then the reliability is improved, but the productivity of the setup process deteriorates
Solution Approach 1:
The invention extracts the essential pairing function from complex verification procedures by implementing a simplified mechanism: holding the actuator near the sensor body automatically triggers ID detection and storage. This extraction maintains reliability through secure ID-based association while dramatically improving setup speed by eliminating unnecessary complex verification steps.

AI summary
A safety switch includes a sensor body. The sensor body includes: a setting unit configured to set an operation mode of the safety switch; a detection unit configured to detect an actuator; a storage unit; and a control unit configured to control storage operation of the storage unit for identification information of the actuator. In response to satisfaction of conditions where: the operation mode is set by the setting unit to a pairing mode for associating the sensor body and the actuator with each other; the identification information of the actuator is not stored in the storage unit; and a first actuator is detected by the detection unit, the control unit allows the detection unit to acquire identification information of the first actuator and the storage unit to store the identification information.
