Shared Display Control for Multi-Workstation Spinning Machines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Textile spinning machines with multiple workstations require independent maintenance and control, leading to high costs and inefficiencies due to the need for individual displays at each workstation, while existing solutions either provide incomplete information or require significant production effort.
Innovation Solution
A method where one display is assigned to multiple workstations, with information displayed in subareas that can be dynamically resized and reconfigured based on workstation states, using icons and touch-sensitive interfaces to ensure quick access to essential information without reducing overall information content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If each individual workstation is equipped with its own display device, then complete information availability for each workstation is achieved, but production costs and device complexity increase significantly
Solution Approach 1:
Multiple display devices that were previously assigned to individual workstations are merged into a single shared display device. The display is divided into multiple subareas, with each subarea assigned to a specific workstation, allowing one display to serve multiple workstations simultaneously while maintaining complete information availability for each.
Solution Approach 2:
The display device is segmented into multiple subareas, where each subarea can independently display information for a specific workstation. This segmentation allows the single display to present multiple streams of information simultaneously without confusion, resolving the contradiction between reducing display quantity and maintaining information completeness.
2Device complexity
If one display is shared among multiple workstations, then device complexity and costs are reduced, but the display area available for each workstation is reduced
Solution Approach 1:
The subareas of the display are designed to be dynamic in size rather than fixed. When a workstation requires attention (e.g., malfunction, maintenance needed), its corresponding subarea automatically enlarges to provide more display space for relevant information. During normal operation, subareas maintain smaller sizes to accommodate more workstations. This dynamic adjustment resolves the contradiction between shared display reduction and sufficient display area per workstation.
3Device complexity
If display subareas have fixed sizes, then device complexity is reduced, but adaptability to different operational states is limited
Solution Approach 1:
The display subareas transition from fixed to dynamic sizing based on workstation operational states. When workstations are in normal operation, subareas maintain standard sizes. When a workstation enters a state requiring attention (malfunction, maintenance, operator intervention needed), its subarea automatically enlarges to provide enhanced information display. This dynamic behavior provides high adaptability while maintaining relatively simple control through automated state detection.

AI summary
A method for controlling a display on a spinning machine or winder having a plurality of same-kind workstations and a plurality of displays includes assigning one of the displays to at least two of the workstations, wherein each display includes a display area. During normal operation of the workstations, information regarding the individual workstations assigned to the particular display is simultaneously displayed in respective subareas of the display area. When required by changed operating states at the work stations, a surface area of the subareas is changed to display information regarding at least one of the workstations on a larger subarea. An associated spinning machine or winder is also provided.
