Textile Machine Service Unit Priority Control for Faster Manual Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing textile machine service units face inefficiencies due to long waiting times for manually requested service activities and movement orders, which hinder quick adjustment and maintenance work, leading to decreased productivity and reliability.
Innovation Solution
The method prioritizes evasive trips and parking orders with the highest priority, and manually set service activities and movement orders with high priority, ensuring immediate execution of essential tasks by the service employee, while automatically generated orders are processed subsequently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If manually set service activities and movement orders are processed after automatically generated orders, then automatic operation smoothness is maintained, but waiting time for service employees increases significantly
Solution Approach 1:
The control device dynamically adjusts the priority of service orders based on their type and origin. Manually set service activities and movement orders are assigned high priority to enable service employees to perform adjustment and maintenance work immediately, while automatically generated orders are processed subsequently. This dynamic prioritization resolves the contradiction by making the system adaptable to different operational contexts.
Solution Approach 2:
The control device receives feedback from service employees through manual input of service activities and movement orders. This feedback mechanism allows the system to respond to actual operational needs and prioritize tasks accordingly, reducing waiting time and improving service employee productivity while maintaining smooth automatic operation.
2Productivity
If service employees perform adjustment work immediately upon request, then productivity increases, but conflicts between multiple service units may occur
Solution Approach 1:
The control device dynamically determines the execution sequence of service orders by considering their priority level and current machine state. This dynamic scheduling ensures that service employees can perform adjustment work efficiently while the system maintains operational reliability by coordinating multiple service units to avoid conflicts.
Solution Approach 2:
The control device processes evasive trips and parking orders with the highest priority before executing manually set service activities. This preliminary action ensures that potential conflicts between service units are resolved in advance, maintaining operational reliability while enabling efficient service employee work.
3Reliability
If all service orders are processed in strict priority sequence, then operational conflicts are avoided, but adjustment and maintenance work experience delays
Solution Approach 1:
The control device uses dynamic priority assignment where manually set service activities and movement orders receive high priority, while automatically generated orders are processed subsequently. This dynamic approach ensures that adjustment and maintenance work experiences minimal delays while operational conflicts are still avoided through coordinated execution.
Solution Approach 2:
Different priority levels are assigned to different types of service orders based on their specific requirements. Manually set orders requiring service employee intervention are given high priority locally, while automatic orders are processed in the background, resolving the contradiction between reliability and waiting time.
4Productivity
If service units operate with high automation, then operational efficiency increases, but flexibility for manual adjustments decreases
Solution Approach 1:
The control device serves multiple functions by processing both automatically generated service orders and manually input service activities. This multi-functionality allows the system to maintain high automation for routine operations while providing flexibility for manual adjustments when needed, resolving the contradiction between operational efficiency and adaptability.
Solution Approach 2:
The system dynamically switches between automatic and manual operation modes based on service order type. Automatically generated orders maintain high operational efficiency, while manually set orders provide adjustment flexibility, making the system universally applicable to different operational contexts.
