Mobile Data Relay for Isolated Laser and Machine Tools
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Laser and machine tool devices often lack network connectivity, limiting data exchange and requiring manual updates for location and time data, which complicates maintenance and operation, especially when direct network connections are not available.
Innovation Solution
A system using a mobile terminal device to establish point-to-point wireless connections with these devices for data synchronization, enabling automated data exchange without internet access, using Bluetooth LE or WLAN for communication, and allowing location and time data to be updated automatically.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If laser or machine tool devices are not connected to any external network or only connected to a network that does not allow connections to other devices or external networks, then device security and network isolation are maintained, but data exchange between devices is hindered and manual updates are required
Solution Approach 1:
A mobile device (smartphone, tablet, or laptop) serves as an intermediary between isolated laser/machine tool devices, enabling data exchange without requiring the devices to be directly connected to external networks. The mobile device temporarily connects to each device via Bluetooth or WLAN, downloads data, stores it locally, and later uploads it to other devices, thus mediating communication while preserving network isolation and security
2Object-affected harmful factors
If devices are isolated from external networks, then security policies and network restrictions are maintained, but automated data synchronization and location determination are prevented
Solution Approach 1:
The system enables devices to perform self-service data synchronization through the mobile device intermediary. When the mobile device connects to a device, it automatically downloads available data, compares it with previously stored data, identifies new information, and later automatically uploads relevant data to other devices without requiring manual intervention or network connectivity for the isolated devices
Solution Approach 2:
The mobile device acts as a mediator that performs automated data synchronization operations between isolated devices. It retrieves location and time data from external sources, manages data storage and comparison, and handles the transfer of condition monitoring data, error messages, and status information between devices without requiring them to breach security policies
3Device complexity
If manual updates of location and time data are performed, then network connectivity requirements are reduced, but time consumption and operational efficiency decrease
Solution Approach 1:
The mobile device serves as an intermediary that automatically retrieves current location data (via GPS) and time data (via internet connection or time servers) and transfers this information to the isolated devices during Bluetooth or WLAN connections, eliminating the need for manual updates while maintaining minimal network connectivity requirements

AI summary
The invention relates to a system (1) for transmitting data, comprising at least one laser device or machine tool device (2) which has a communication device (5) for establishing a local wireless point-to-point connection, at least one external data interface (15), and at least one mobile terminal (3) which can be connected to the external data interface (16) and which has a data storage device (12) and a communication device (6) for establishing a local wireless point-to-point connection and is connected either to the at least one device (2) or to the external data interface (16). The system (1) is designed to transmit data of the at least one device (2) to the mobile terminal (3) via a local wireless point-to-point connection (4a), to buffer the data in the data storage device (12) at the mobile terminal, and to transmit said buffered data from the mobile terminal (3) to the external data interface (16) after the point-to-point connection (4a) has been concluded or vice versa. The system also comprises at least one additional laser device or machine tool device (2a, 2b) which has at least one external data interface (14) and a communication device (5) for establishing a local wireless point-to-point connection. The system (1) is designed to transmit data of one device (2a) to the mobile terminal (3) via a first local wireless point-to-point connection (4a), to buffer the data in the data storage device (12) at the mobile terminal, and to transmit said buffered data from the mobile terminal (3) to the other device (2b) via a second local point-to-point connection (4b) after the first point-to-point connection (4a) has been concluded.
