Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for establishing a secure connection and activating or testing the emergency stop functionality in systems comprising a main machine tool and an auxiliary device are complex, costly, and not cost-effective.
Innovation Solution
A method that involves sending connection requests and responses between the main machine tool and the auxiliary device, with verification by a control device, and activating the emergency stop functionality using a single actuating device, allowing for a secure, simple, and cost-effective connection establishment and emergency stop testing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a secure connection is established through pairing and authentication procedure with separate input device and actuating device, then communication security is improved, but device complexity and operational complexity increase
Solution Approach 1:
The patent combines the input device and actuating device into a single integrated actuating device on the auxiliary device. This single device performs both authentication input and emergency stop activation functions, eliminating the need for separate devices while maintaining security through the control unit's verification of signals within a predetermined time period.
Solution Approach 2:
The actuating device on the auxiliary device is designed with multi-functionality, serving both as an authentication input device for establishing secure connections and as an emergency stop activation device. This universal design reduces the total number of components while preserving both security and emergency functionality.
2Reliability
If separate input device and actuating device are used for connection establishment and emergency stop activation, then functional separation is improved, but ease of operation deteriorates
Solution Approach 1:
The patent merges the input device and actuating device into a single integrated actuating device, allowing users to perform both connection establishment and emergency stop activation through one device. This integration simplifies the user interface and operational steps while the control unit maintains functional separation through signal verification protocols.
3Reliability
If multiple devices and complex procedures are used for connection and emergency stop testing, then security verification is improved, but loss of time increases
Solution Approach 1:
The control unit is pre-configured with verification logic that automatically checks signals from the integrated actuating device within a predetermined time period. This preliminary setup of verification mechanisms allows for rapid authentication and emergency stop activation without requiring multiple manual verification steps, reducing activation time while maintaining security.
