Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing textile machines, particularly spinning machines, face challenges in producing consistent yarn quality due to series-specific differences, aging phenomena, and manufacturing tolerances, making it difficult to apply the same recipes across machines of different series and operators.
Innovation Solution
An article management system provides article-specific operating parameters, combined with machine-specific correction factors to adapt settings to individual machine conditions, ensuring consistent quality across machines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the same recipe (operating parameter set) is applied to multiple textile machines of different series and ages, then the device complexity is reduced and ease of operation is improved, but the manufacturing precision and reliability of yarn quality deteriorate due to series-specific differences, aging phenomena, and manufacturing tolerances
Solution Approach 1:
The patent applies local quality by introducing machine-specific correction factors that adjust the general recipe to account for individual machine characteristics. Each machine receives a customized parameter set based on its series, age, and performance data, allowing the same base recipe to be adapted locally to each machine's specific conditions while maintaining overall system standardization
Solution Approach 2:
The system dynamically changes operating parameters by applying correction factors to the base recipe values. These correction factors modify speed ratios, tensions, and other critical parameters based on machine-specific data, enabling the system to adapt to aging and manufacturing variations without requiring complete recipe redesign for each machine
2Manufacturing precision
If machine-specific correction factors are introduced to adapt recipes to individual machine conditions, then the manufacturing precision and reliability of yarn quality are improved, but the device complexity increases due to additional correction factors and calculation requirements
Solution Approach 1:
The correction factor system serves multiple functions simultaneously: it compensates for aging effects, adjusts for manufacturing tolerances, adapts to different machine series, and maintains recipe consistency across the fleet. This universal approach handles diverse machine variations through a single unified mechanism rather than requiring separate adjustment systems for each issue
Solution Approach 2:
The system creates a standardized correction factor model that can be copied and applied across multiple machines. Once correction factors are determined for a particular machine series or type, they can be replicated to similar machines, reducing the overall complexity by avoiding the need to manually tune each individual machine from scratch
3Manufacturing precision
If numerous tests are conducted to determine suitable operating parameters for each machine, then the manufacturing precision is improved, but the loss of time and productivity deteriorate due to the extensive testing required
Solution Approach 1:
The system performs preliminary action by pre-determining correction factors based on machine series, age, and historical performance data before actual production begins. This allows the machine to start production with pre-optimized parameters rather than requiring extensive on-site testing, significantly reducing setup time while maintaining precision
Solution Approach 2:
The system uses feedback from yarn quality measurements and machine performance data to continuously refine correction factors. Rather than requiring extensive initial testing, the system quickly adapts by learning from actual production data, reducing the time needed to achieve optimal parameters while maintaining high manufacturing precision
