Solution Overview
Problem
Existing converters for converting fibers into staple fibers lack flexibility and precision in adjusting cutting gaps, leading to inefficiencies and increased costs due to complex configurations and assembly requirements.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple cutting gaps are adjusted independently using separate setting units, then adjustment flexibility and precision are improved, but device complexity and assembly effort increase
Solution Approach 1:
The adjustment mechanism is divided into two independent levels: a central setting unit that adjusts all cutting gaps simultaneously, and individual setting units that can adjust specific cutting gaps independently. This segmentation allows the system to achieve both precise individual adjustments and coordinated global adjustments without requiring separate adjustment mechanisms for each cutting gap, thereby reducing overall complexity.
Solution Approach 2:
The central setting unit serves multiple functions by simultaneously adjusting all cutting gaps associated with different fiber exit units. This multi-functional design eliminates the need for separate adjustment mechanisms for each cutting gap, reducing the total number of components while maintaining the ability to precisely control each individual cutting gap through the combination of central and individual setting units.
2Manufacturing precision
If a complex configuration with multiple separate setting units is used, then adjustment precision is improved, but assembly effort and costs increase
Solution Approach 1:
The central setting unit combines multiple adjustment functions into a single integrated mechanism that can simultaneously control all cutting gaps. By merging the adjustment capabilities for multiple cutting gaps into one unified structure, the patent reduces the total number of separate components that need to be assembled, thereby reducing assembly effort and manufacturing costs while maintaining precise control over each cutting gap through the combination of central and individual setting units.
3Measurement precision
If thermal setting units are added to control temperature, then setting precision is maintained during operation, but device complexity increases
Solution Approach 1:
The thermal setting unit automatically detects and compensates for temperature-induced changes in the cutting gap by using thermal expansion principles. The unit self-regulates by expanding or contracting to maintain the correct cutting gap dimension despite temperature variations, eliminating the need for complex active control systems while maintaining setting stability during operation.
Solution Approach 2:
The thermal setting unit utilizes changes in thermal expansion parameters to automatically adjust the cutting gap. By designing the unit to expand or contract with temperature changes, the system maintains constant cutting gap dimensions without requiring complex active control mechanisms, thereby adding thermal compensation capability while minimizing increased device complexity.
