Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current operating devices for textile machines lack flexibility in user authorization and remote operation capabilities, failing to adapt to different user tasks and not enabling secure remote access.
Innovation Solution
An operating device with a switching function between basic and expert modes, along with remote transmission and receiving functions, allowing users to authorize and adapt operations based on their roles, and enabling secure remote operation of textile machines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single operating mode is provided for all users, then the device complexity is reduced, but the adaptability to different user tasks and authorization levels deteriorates
Solution Approach 1:
The operating device is segmented into multiple operating modes (basic mode and expert mode) with distinct functional interfaces. Basic mode provides simplified operation for general users, while expert mode offers comprehensive control for authorized personnel. This segmentation allows the system to adapt to different user needs without requiring a completely different device for each user type.
Solution Approach 2:
The operating device dynamically switches between different operating modes based on user authorization and task requirements. The system can transition from basic mode to expert mode when appropriate authorization is provided, and vice versa. This dynamic adaptability allows the same device to serve multiple user types and task complexities without increasing physical device complexity.
2Adaptability or versatility
If remote operation capabilities are added to the operating device, then the versatility of operation is improved, but the security risks and system complexity increase
Solution Approach 1:
A security intermediary layer is introduced between the remote user and the textile machine control system. This intermediary verifies user authorization, manages authentication credentials, and controls access to different operating modes. The intermediary ensures that remote operations are securely authorized before granting access, thereby maintaining system security while enabling remote operation versatility.
3Adaptability or versatility
If multiple operating modes with different authorization levels are implemented, then the adaptability to user roles is improved, but the ease of operation deteriorates due to additional authorization steps
Solution Approach 1:
The operating device incorporates self-service authentication mechanisms that automatically manage user authorization. When a user attempts to access expert mode, the system automatically verifies their credentials and transitions them to the appropriate operating mode without requiring manual intervention from operators. This self-service approach maintains ease of operation by automating the authorization process while still providing role-based adaptability.

AI summary
A first operating device for operation of a textile machine includes a basic mode function and an expert mode function for operation of the textile machine by a user. A switching function allows the user to switch between the basic and expert mode functions. A remote transmitting function provides for communication to a second operating device assigned to a remote textile machine so that the user at the textile machine can operate the remote textile machine in the basic or expert mode via the first and second operating devices. A remote receiving function provides for communication from the second operating device assigned to the remote textile machine so that a remote user can operate the textile machine in the basic mode or expert mode from the remote textile machine via the second and first operating devices.
